The Doppler Effect talks about the frequency of sound and light as the source and person move. So, When light waves are emitted by a moving source, scientists can measure = the Doppler effect.
Cosmic microwave background radiation has the word "cosmic" in it, so you can assume it has to do with space automatically. There is radiation in space too, so I'm pretty sure that The extremely low temperature of outer space can be explained as = cosmic microwave background radiation.
Particle accelerators are these big machines that usually smash protons/electrons together, so Scientists smash together tiny bits of matter using = particle accelerators.
And now, by process of elimination and because the Big Bang Theory talks about the creation of Earth, we know that Scientists extrapolate backwards in time to derive = the Big Bang Theory.

What is added to tacos, burritos, and soups that is
high in fiber?
Answer: flax seed whole wheat tortillas.
1⁄2 cup low-fat refried beans.
1⁄4 cup low-fat cheddar cheese.
leaves lettuce.
1⁄ cup salsa.
1⁄4 cup fat free sour cream.
Pinto beans are added to tacos, burritos, and soups that are high in fiber.
What are fibers and their types?The body is unable to digest fiber, which is a form of carbohydrate. While fiber cannot be converted into glucose, the sugar that results from the breakdown of most carbs, fiber travels through the body undigested.
The solubility, viscosity, and fermentability of dietary fibers, which have an impact on how they are metabolized by the body, can be used to classify them in general. Dietary fibers have a wide range of chemical compositions.
Fibre comes in two varieties: soluble and insoluble. Both are crucial for good health, digestion, and illness prevention. Thus, Pinto beans are added to tacos, burritos, and soups that are high in fiber.

A 45-year-old woman named Christine is measured as having the following skinfold thicknesses on the right side of her body: Triceps: 14mm; Thigh: 32mm; Suprailium: 28mm. Estimate her body fat percentage.
Answer:
The skinfold method, the measurement of subcutaneous fat folds, is the most widely adopted field method for the assessment of body fat, especially in children.
It is based on the principle that fat is of a known density and by “summing” measurements of subcutaneous fat thickness across the body, total and regional fat can be estimated.
Skinfold thickness measurements are typically used to rank individuals in terms of relative total “fatness”, or to assess subcutaneous fat at various regions of the body.
Population specific equations are used to derive estimates of percent body fat.
In infancy, it might be the sole tool available for assessing body composition longitudinally as other methods may not be feasible, or may only be suitable for use at body sizes e.g. PEA POD, can only measure infants up to 10kg.
The most generally used field method for determining body fat, particularly in kids, is the skinfold method, which involves measuring subcutaneous fat folds.
What is skinfold method?Skinfold method is defined as a method for determining how much body fat there is. It entails delicately pinching the skin and underlying fat in several locations using a tool called a caliper. To acquire precise findings using this quick and easy body fat estimation technique, a high level of competence is needed.
It is based on the idea that since subcutaneous fat thickness measurements may be "summed" to estimate total and regional fat because subcutaneous fat has a known density. Measures of skinfold thickness are widely used to categorize individuals based on their relative degrees of overall "fatness" or to assess subcutaneous fat in various bodily regions. Estimates of the percent body fat are derived using equations that are specific to a population.
Thus, the most generally used field method for determining body fat, particularly in kids, is the skinfold method, which involves measuring subcutaneous fat folds.

A biologist thinks the population of chipmunks will be in the range of 2900 to 3100 in the year 2000. Is that a reasonable guess? Why or why not?
Answer:
No
Why not:
The midpoint of range is 3000. Yes, in from 1950-1955 there was a massive increase of the population of chipmunks but from then on it slowly decreased until 1990. In 1995, the population doubled from 1990. If you double 1440, you will get 2880. The biologist said between 2900-3100, using the midpoint of this range (3000) it is too low therefore being a bit unreasonable.

Individuals with premutation length repeats in FMR1 may have some of the phenotypes of Fragile X but not others, which is _____________; for example, some individuals may have cognitive deficiencies, while others might have late onset ataxia. In addition, some individuals will have no phenotypes of the condition at all, due to ____________.
Answer:
variable expressivity; incomplete penetrance
Explanation:
In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.

In pea plants, flowers are either white or purple: the purple color is produced by pigments called anthocyanins. The production of anthocyanins is a two-step process: the first step is controlled by the C gene and the second by the P gene. Both genes must produce functional proteins for anthocyanin to be produced. This is an example of:
Answer:
This is an example of gene translation.
Explanation:
Gene translation refers to the genetic process where a set of genes is used to create amino acids that will be responsible for creating a protein needed to perform some function or characteristic of the organism. In the question above, we can see that anthocyanin, responsible for the pigment of flowers, is created through the work of proteins that are created from gebes C and P. This is an example of gene translation, as it presents the formation of proteins regulated by genes.

The extinction vortex represents the idea that even if an organism is extant, it may have a gene pool that will not support its long-term survival.A. TrueB. False
Answer:
True.
Explanation:
Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.
What is the biggest problem of over use of pesticides

There have been many issues that have been seen to arise due to the over use of pesticide including:
Explanation:
Overuse has been linked to cancer, Alzheimer's Disease, ADHD, and even birth defects. Along with being reporting to have the potential to harm the nervous system, the reproductive system, and the endocrine system.
Answer:
Pollution.
People applying them are exposed to toxic chemicals. People who live nearby can be exposed too with wind blowing them around.
With rain or just watering of plants, the pesticides 'run off' and end up in water supplies, rivers, lakes, and eventually oceans.
Also, organisms can mutate and make pesticides useless.
Cystic fibrosis is most common in individuals of Northern European descent, affecting 1 in 3200 newborns. Assuming that these alleles are at Hardy-Weinberg equilibrium, what is the frequency of the disease-causing CFTR alleles in this population
Answer:
0.0177
Explanation:
Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:
1/3200 = q² (have two CFTR mutant alleles) >>
q = √ (1/3200) = 1/56.57 >>
- Frequency of the CFTR allele q = 1/56.57 = 0.0177
- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823
In a test cross, a pure-breeding plant is crossed with a plant suspected to be heterozygous (Aa). What is the genotype of the pure-breeding plant?
Answer:
aa
Explanation:
In genetics, a test cross is a cross performed to determine the unknown genotype of a phenotypically dominant organism. The test cross is done by crossing the unknown genotype with a homzygous recessive organism. The result of this cross tell us whether the unknown genotype is heterozygous or homzygous dominant.
According to this question, a test cross was conducted involving a pure breeding plant with a plant suspected to be heterozygous (Aa). Based on the explanation of a test cross above, the genotype of the pure-breeding plant will be "aa". Note; it must be recessive.
II. Sequencing Directions: Arrange the procedure/steps to fold a banana table napkin by writing 1 to 8 on the blank before the number.
Repeat the last step with the left side, folding the left tip up to the far corner, creating a diamond shape with a seam running down the center.
Fold the right end up to meet the far corner, ensuring the edge of this new fold lays on the centerline as shown.
Stand it up and tug at it where needed to even it up and out. If your napkins are too limp, then think of starch as a napkin and make them good and stiff round it.
Lay the napkin face down in front of you. Curl the left and right sides of the napkin up so they meet in the middle and tuck one into the other.
Fold the bottom of the napkin up about 2/4's of the way and press this fold down well. Fold the napkin in half diagonally. Orient the napkin so the open ends point away from you.
Fold the smaller triangle down so the point rests on the near edge of the napkin. Press.

STEP 3: TURN IT
Turn the triangle so that the longest side is parallel to you and the table's edge.
STEP 4: FOLD IN
Fold the left corner in so that it sits JUST past the midway point of the long side of the triangle, like pictured.
STEP 5: FOLD IN AGAIN
Now repeat for the right hand corner.
STEP 6: FOLD OVER
Take the lower left corner and bring it in to the bottom midpoint of the now 'house' shaped napkin. Press the new left side fold down.
STEP 7: FOLD OVER AGAIN
Repeat on the right side.
STEP 8: FOLD UP
Take both bottom corners and bring them up to rest just below the top right corners. Press down the new folds.
STEP 9: CLOSE THE ENVELOPE
Take the top point of the envelope 'flap' and bring it down (or close it) to complete the envelope.
STEP 10: ADD A PERSONALIZED CARD
Use your envelope napkins to include a personalized 'letter' or card to each guest's plate. Some ideas for what this could be are:
holiday greeting card
menu
place card
family photos from past celebrations
holiday story or poem
coloring cards with pencil crayons for kids
game cards: trivia, scavenger hunt, etc
Further studies of the genes in the region around the MHC locus identified C4 as a likely causative gene. A particular allele of C4 was significantly associated with schizophrenia. In addition, it was found that individuals with high expression of this allele of C4 had elevated risk of developing schizophrenia. Which of the following variants would be most likely to increase risk of schizophrenia from this allele?
a. a variant that decreases binding of an activating transcription factor to the C4 promoter
b. a 5’ UTR variant that destabilizes the C4 mRNA
c. a duplication of the C4 gene
d. a nonsense coding variant
Answer:
c. a duplication of the C4 gene
Explanation:
Schizophrenia is a disease that affects the brain, which is characterized by an imbalance of neurotransmitters and the presence of damaged brain tissues. In humans, the Complement component 4 (C4) protein is found at the neurons (i.e., cell bodies, dendrites and axons), which are the most common brain cells, and neuronal synapses. Moreover, gene duplication can increase gene expression when repressive mechanisms (e.g., DNA methylation at promoter sites) capable of silencing the expression of the duplicated gene are lacking. Recently, it has been discovered that a chromosome rearrangement associated with a tandem duplication of a genomic region that contains a C4 gene may contribute to schizophrenia risk by increasing the expression of this gene. In this example, a, b and d options are associated with a decrease in expression of the C4 gene, either by decreasing its transcription (options a and d) or by posttranscriptional mechanisms (option c).

oxygen is carried by blood to all the cells of body in the form of ___________
Answer:
Oxygen is carried by blood to all the cells of the body in the form of haemoglobin.
Explanation:
Oxygen is carried in the blood in two forms:
(1) dissolved in plasma and red blood cells water (about 2% of the total)
(2) reversibly bound to haemoglobin (about 98% of the total).
Haemoglobin is a protein in the red blood cells and carries oxygen around our bodies. At the same time, carbon dioxide that is dissolved in the blood comes out of the capillaries back into the air sacs, ready to be breathed out.

Answer:
The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.
Explanation:
Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.

7. Shawn plotted the data in a bar graph with two bars: one representing the number of bees per colony in the control cages and the other representing the number of bees per colony in the cages exposed to the fungicide. If the results support the hypothesis that fungicides harm bee development, what would you expect this bar graph to show? Describe the expected pattern in a few sentences.
Answer:
The first bar increases in length as compared to the second bar.
Explanation:
The length of the bar of control cages in graph increases because the number of bees per colony increases while on the other hand, the length of the bar of the cage that is exposed to fungicides decreases because the bees are negatively affected from the application of fungicides. They act abnormal in behaviour and adversely affected the reproduction of bees that greatly affected its population.
