The idea that chromosomes orient themeselves randomly during metaphase I is ________________________. This leads to ___________________ combinations of genes.

Answers

Answer:

The idea that chromosomes orient themselves randomly during metaphase I is Independent Assortment. This leads to more combinations of genes.

Explanation:

During metaphase I, the pair of chromosomes align in the plate of the cell. In this step, the independent assortment takes place.

The independent assortment is the distribution of different genes into two gametes, is independent, because the distribution of the different genes, does not influence the distribution of the other genes. The independent assortment leads to new combinations of genes from the parental and maternal side, resulting in offsprings that do not look exactly like their parents.

Place the following materials in the order in which they are likely to fossilize. Begin with the material that is most likely to fossilize, and finish with the material least likely to fossilize.
1. mammal teeth
2. bones of an adult mammal quickly buried
3. bones of an adult mammal left on the surface
4. soft body parts of any animal

Answers

Answer: correct order--->

1)mammal teeth

2.)bones of an adult mammal quickly buried

3.) bones of an adult mammal left on the surface

4.)soft body parts of any animals

Explanation:

Fossilization is the ability of an organism to be preserved and remain unaltered for a very long time. Through research , it has been found out that Harder  parts of the body tend to remain preserved for a long time  because they  naturally have minerals deposited in them and may only be reduced,  but the softer part or tissues do not get preserved for a long time because being made up of polymer can be disintegrated easily by natural biological and physical processes.

The order of which material will likely fossilize is

1.)mammal teeth

2.)bones of an adult mammal quickly buried

3.) bones of an adult mammal left on the surface

4.)soft body parts of any animals

Reason,

--Teeth and bones biologically contain calcium but the teeth is more tougher and durable than the bone, Even when a  body is decomposed, the teeth most times are not  affected at all.

Bones of an adult mammal left on the surface will decompose faster than the one buried because of the biological (natural decomposing ) and physical processes(temperature, wind, sunglight, rainfall ) which will both act on it at the same time because of its exposure.

- soft body parts of any animals will decompose fastest as bacteria will feed on it immediately since it lacks minerals that can elongate preservation.

ASAP Why is ATP used as an active energy source over glucose? A. It is more abundant in food sources. B. It releases its energy quickly in a single reaction. C. It releases its energy slowly through multiple reactions, allowing it to last longer. D. It has more energy.

Answers

Answer:

B.

Explanation:

Glucose is an organic molecule that stores ATP or energy while Adenosine triphosphate (ATP) is an energy-carrying molecule.

ATP used as an active energy source over glucose because ATP is a shorter process and releases energy in a single reaction as glucose first converted into ATP and then used as energy in cellular respiration.

Hence, the correct option is "B".

How does your body know when cells are missing

Answers

Answer:

Receptors provide information to nervous system about missing cells.

Explanation:

Your body know when cells are missing due to nervous system. The network of nervous system spreads throughout human body which provide information about what is going on in the body. If the cells are missing due to injury, the nervous system gives instruction to the body to produce more cells and transported that cells to the region where these cell are required. So receptors are responsible to provide information to nervous system about missing cells.

The body knows cells are missing as a result of the receptors sending

to the central nervous system.

The human body consists of cells which have neurons. These neurons are

responsible for the passage of messages and information to other parts of

the body.

When a cell is missing from the body, signals are passed to the central

nervous system which consists of the brain and spinal cord and they then

relay impulses which helps to fix the issue so as to ensure optimal

If a cusp is lost during preparation, which matrix band would provide the best support while restoring

Answers

Answer:

I would use a specialized or preformed matrix for the posterior sector.

Explanation:

Losing a cusp is a much more critical situation, that is, there will be less tooth remnant and less resistance to functional and parafunctional forces.

The matrices that are usually used in the posterior sector are matrices that must be burnished and already come with a format to better restore the functional unit of the occlusal surface.

It is important to clarify that cusps are only in the posterior sector and not in the anterior sector.

The cusps, even if they have the most correct selection of the matrix, will fail in their restoration if they are not performed according to the patient's occlusion, under a good dental integration system such as adhesion through resins, and respecting the normal antomy of the piece to be restored.

Explanation:

In the first case is imperative to obtain more information in order to determine the causes of this contagious disease (contaminated seafood may be associated with different types of infections).

Vibrio vulnificus is a Gram-negative pathogenic bacterium associated with the consumption of contaminated oysters. V. vulnificus causes gastroenteritis, necrotizing infections and invasive sepsis.  

Jaundice is a condition caused by hepatitis A, B and E viruses, it is a disease associated with poor liver function and the destruction of red blood cells.  

Cryptosporidium parvum is a protist parasite (Phylum Apicomplexa) that causes the diarrheal disease cryptosporidiosis. C. parvum parasite is present in contaminated foods and water.

Salmonella enterica is a Gram-negative bacterium transmitted by eating contaminated foods, which causes severe diarrhea, fever and abdominal pain. Salmonella infection may also cause inflammatory diseases and dehydration.

Thichinella spiralis is a parasitic nematode that causes the trichinosis, a disease where larvae migrate to muscle, thereby producing muscle pains and serious pathologies. Trichinosis is caused by eating undercooked meat from contaminated animals.

After entering a dark room, you turn on a light switch, but the light does not come on. Please suggest three different hypothesis that might explain your observation. Please also note how you might test these hypotheses and describe what observation(s) may lead you to conclude that one of the hypothesis is correct.

Answers

Answer:

First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout  ( light bulb may not be working )

Explanation:

The three possible hypothesis for light not to turn on immediately after one on the switch are;

First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout  ( light bulb may not be working )

We test the first hypothesis, how?

We check if other electronics connected to the same sources of power supply as the bulb is working. If the electronics are not working, then the first hypothesis is correct but if they are working then the hypothesis fails and we move on to test the next hypothesis.

To test for the second hypothesis as the first hypothesis fails, we remove the bulb and fix it into another socket which has a working switch. If the bulb comes on then the second hypothesis is correct but if the bulb does not turn on then the hypothesis fails so we move on to test the third hypothesis.

As the bulb fails to turn on in our initial socket and a second bulb is fixed in that same socket and it came on, then the third hypothesis is correct.

The three hypotheses we can derive from entering a dark room, turning on a

light switch,and the light not coming on include

There may be no power source at that momentThe bulb may be faultyThe switch may be faulty

A power source helps to provide energy to power up an appliance and where it is absent, the bulb won't light up.

A defect in the switch and bulb may also hinder the light from coming on as

the switch controls electric current flow while the bulb produces the light.

You are observing a sample of cells in the lab to determine why they did not
divide properly. You notice that the chromosomes are lined up in the middle
of the cell, and the spindle fibers have extended towards them, but have not
attached. What could be damaged?

Answers

The kinetochore of the chromosomes


Explanation:
What could be damaged that is hindering the spindle fibers from attaching to the chromosomes are the kinetochores of the chromosomes.
At the metaphase stage of the cell division, the chromosomes align at the equator of the cell and the spindle fibers engage each chromosome at a region known as the kinetochore.
The kinetochore is made up of complex proteins and lies around the centromere region of the chromosome. The microtubules of the spindle fibers attach to this region during the metaphase stage.
If the kinetochore is damaged, it means the spindle fiber will not be able to attach to the chromosome.

identify a probable reason that the dark moths survived while the light moths did not during the industrial revolution

Answers

Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. Biston betularia, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

probability of such a child be determined?
You must draw a Punnett square within the space provided to receive any credit for your answer!

Answers

Answer:

Yes, a child with normal vision who does not suffer from headaches can be produced.

The probability of producing such child from this cross is 1/2 or 50%

Explanation:

This question involves two distinct genes in humans. One coding for blindness and the other for Migraine headaches. The alleles for blindness (B) and Migraine (M) are dominant over the alleles for normal vision (b) and no Migraine (m).

According to the question, a male who is heterozygous for blindness and does not suffer from migraines will have the genotype; Bbmm while a female who

has normal vision and does not suffer from migraines will have genotype; bbmm. If these two parents are crossed, the following genotypes of gametes will be produced by each parent:

Bbmm- Bm, Bm, bm and bm

bbmm- bm, bm, bm, and bm

Using these gametes to construct a punnet square (see attached image), the following offsprings with genotypes; Bbmm and bbmm in the ratio 1:1 will be produced.

Bbmm (8/16) are offsprings with blindness and have no Migraine headache

bbmm (8/16) are offsprings with normal vision and have no migraine headache

Hence, this cross can produce a child with normal vision who does not suffer from headaches (bbmm). Also, the probability of producing such child is 8/16 or 1/2.

On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded, releasing radioactive isotopes into the air. The majority of the isotopes that were released and spreading thousands of miles were of the element iodine. As a class, discuss what endocrine glands would be most affected and how it would become apparent in the nearby population.

Answers

Answer:

In the given case, the thyroid gland will be affected the most due to the exposure of the element iodine. For the synthesis of thyroid gland hormone, T3 and T4 iodine is required. As the exposure of the radioactive iodine element is taking place, therefore, it will result in the deterioration of the thyroid gland. Radioactive iodine is generally used in the treatment of hyperthyroidism.  

However, in normal individuals, the exposure of the radioactive iodine element results in a decrease in the level of thyroid hormones below the normal level due to the destruction of the thyroid cells. The symptoms seen can be neck tenderness, swollen salivary gland, and loss in body weight.  

The thyroid gland will be mostly affected in this case. The element Iodine is

the major precursor which is involved in the formation of two hormones.

Answers

Answer:

The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.

Explanation:

Purines are produced as bases attached to the ribose 5-phosphate (pentose sugar). The adenine and guanine nucleotides derive from inosine monophosphate (IMP), which is synthesized on an existing ribose-phosphate. Thus, purine bases are built on a ribose sugar that is directly attached to the pyrimidine ring. On the other hand, pyrimidines are produced from the carbamoyl phosphate precursor. In this case, the ribose-5-phosphate pentose sugar is attached after the pyrimidine ring is made.
