The process of ________ involves a carrier protein that can transport a molecule across the cell membrane down its concentration gradient.
Answer:
Answer is Facilitated diffusion.
The process of facilitated diffusion involves a carrier protein that can transport a molecule across the cell membrane down its concentration gradient.
What is facilitated diffusion?The process of spontaneous passive movement of molecules or ions across a biological membrane by particular transmembrane integral proteins is known as facilitated diffusion.
To transfer molecules from one side of the membrane to the other without consuming energy, facilitated diffusion is required. Large and charged molecules require facilitated diffusion more than smaller molecules. These compounds are unable to readily diffuse through the plasma membrane.
It happens when chemicals like glucose or amino acids flow effortlessly from a high concentration to a low concentration.

The gene encoding VEGFR2, the main receptor that binds and is activated by VEGF-A, is transcribed in almost every tissue type, but the VEGFR2 protein is rarely present. List and describe one mechanism that cells could use to reduce VEGFR2 protein levels despite high levels of transcription.
Answer:
The RNA interference (RNAi) mechanism
Explanation:
RNA interference (RNAi) is a biological process by which endogenous non-coding RNAs (ncRNAs) sequences target messenger RNAs in order to inhibit gene expression and translation. The regulatory ncRNAs bind by complementary base pairing to specific mRNAs and thus promote gene silencing by both posttranscriptional (mRNA degradation, block translation, etc) and by transcriptional (recruiting of histone/DNA modifying enzymes) pathways. The most common types of evolutionarily conserved ncRNAs found in plant and animal cells are 1-small interfering RNAs (siRNAs), 2-microRNAs (miRNAs), 3-piwi interacting RNAs (piRNAs, only present in animal cells) and 4-long noncoding RNAs (lncRNAs).

If an experimenter wants to use the GFP method but needs to detect the presence or absence of several proteins at the same time, he can take advantage of mutational variants of GFP that emit what light?
Answer:
different colors
Explanation:
The green fluorescent protein (GFP) is a type of protein widely used in molecular biology laboratories because this protein can be used to detect the expression of proteins and to identify cellular structures. This protein displays green fluorescence when it is excited by blue light and, in the last years, many variants of the GFP protein have been developed. The altered GFP proteins react to distinct wavelengths of light, thereby emitting light to different colors. The mutants forms of the GFP protein are produced by genome engineering techniques that generate modifications capable of altering the folding of the normal GFP protein.
Which of the following is the term for tightly packed sheets of cells that cover organs and outer surfaces?
a. Epithelial tissue
b. Connective tissue
c. Muscle tissue
d. Nervous tissue
Answer:
Epithelial tissue
Explanation:
The correct option would be the epithelial tissue.
Epithelial tissues are made up of tightly arranged cells and primarily functions as protective covers for organs and outer surfaces. Usually, a side of the component cells in epithelial tissue are in contact with organs which they are covering through a non-cellular basement membrane and the other side of the cells are free.
The non-cellular basement membrane that connects the cells in epithelial tissues to organs and surfaces is secreted jointly by the epithelial and connective tissues and usually made up of protein and carbohydrate.
he most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.
The correct answer is A. An infection that migrates via the bloodstream
Explanation:
Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.

Design a controlled experiment to test the effect of water temperature on goldfish. be sure to include your hypothesis, independent variable, dependent variable as well as experimental group and control group.
Answer:
In this experiment, indepedent variable will be temperature and dependent variable will be the respiratory rate of goldfish. Temperature affects the respiratory rate of goldfish, as it's respiratory rate decreases with decrease in temperature of water, the experiment is as follows:
Take two glass containers filled with water A and B and put one goldfish in each container.Measure the temperature of the water using a thermometer.Count mouth movement of both the fishes in certain time.Now put some ice in container B that will decrease the temperature of water and measure the temperature again.Now count the mouth movement of both the fishes for the same time it was counted earlier.The result will be that respiratory rate of goldfish decreases with the decrease in temperature in container B in comparison to container A goldfish.
An experiment meant to determine the cause of an effect, the effect is the independent variable, while the cause is the dependent variable
A controlled experiment to test the effect of water temperature on goldfish is designed as follows:
The experimental group are: The gold fish in a glass Jar X filled with fresh water and with the lid left open (the treatment of temperature reduction is applied to the experimental group)
The control group are: A second gold fish (selected at random) of the same size, in another glass jar Y filled to the same level with fresh water collected from the same source of the first gold fish
Independent variable: The independent variable is the temperature of the water which will be varied by placing ice cube gradually into the glass jar B
Dependent variable: The number times the gold fish gulp air by rising to the surface, and or the number of time goldfish opens its mouth, which indicates that the goldfish is breathing
The hypothesis: The breath rate of goldfish decreases with decrease in temperature because the goldfish metabolic rate decreases and the water holds more dissolved air and therefore oxygen at a reduced temperature
The Experiment Design:
The experiment is conducted by measuring the initial temperature and breathing rate of both fishes
The temperature of the fresh water in jar X is decreased gradually by adding ice cubes and recording the temperature and breathing rate of the goldfish
A similar experiment from an online source (Maryland School improvement website) the following results where obtained
[tex]\begin{array}{|c|cc|} \underline {Breathing \ rate}&&\underline {Water \ Temperature } \\&&\\ (Dependent \ Variable)&&(Independent \ Variable)\ \\&&\\103&&78.8 ^{\circ}F\\78&&68^{\circ}F\\55&&57.2^{\circ}F\\28&&46.4^{\circ}F\\4&&35.6^{\circ}F\end{array}\right][/tex]

If a mother is affected by an X-linked dominant condition and the father is not, which children can inherit the condition?
only males
neither males nor females
both males and females
only females
Answer:
both males and females
Explanation:
The sex chromosomes in male and female humans are X and Y chromosomes. X-linked traits are those traits which are associated with the X- chromosome.
According to the question, the trait is passed on a X-linked dominant condition, which means that the possession or not of the condition is dependent on the presence of the dominant X-chromosome. The dominant X-chromosome will always express itself even when in an heterozygous state with a normal X-chromosome i.e Xx. Hence, only a individual recessive for the X-chromosome will be normal.
A mother that is affected by the X-dominant condition will either possess a; XX or Xx genotype while a father that is normal (not affected) will possess a (xY) genotype. Since the mother passes one of her X chromosomes to her sons and the other to her daughters, both male and female children will be affected by the condition.
N.B: If the mother is heterozygous for the affected X-chromosome (Xx), half of her sons and half of her daughters will inherit the condition but if the mother contains two dominant X-chromosomes (XX), all of her sons and daughters will inherit the condition.

You and your friends go to the beach for vacation. You all walk down to the beach to go swimming. When you get there, you see the water is murky and green, and there are algae blooms floating on top.
Reference: Ref 6-3
If it is excess nutrients which are feeding the algae blooms and lowering the oxygen content in the water, that process is called:
A. nutrient cycling.
B. nitrification.
C. eutrophication.
D. hypoxia.
Answer:
eutrophication
Explanation:
Eutrophication refers to a situation in which the aquatic environment becomes excessively enriched with nutrients. This leads to algal blooms in aquatic habitats such as lakes. These nutrients come from Fertilisers used in farming, which find their way into water bodies through run-off thereby increasing nutrient levels.
Excess nutrients causes phytoplankton to grow and reproduce at an alarming rate resulting in algal blooms. This bloom disrupts the balance in the ecosystem leading to many problems.
The algae may end up using all the oxygen in the water, causing oxygen shortage for aquatic life. Some of the algae may die, their decay may lead to further oxygen depletion. As oxygen is depleted, aquatic organisms may also begin to die.

fur color in mice is affected by a single gene the gene for fur color has two alleles: b that causes dark brown fur and b that causes light brown fur. What is or could be the genotyes of a mouse with dark brown fur
Answer:
(BB) or (Bb)
Explanation:
Given that (B) allele , is responsible for fur that is dark brown, and (b) allele is responsible for fur color that is light brown, the dominant allele is (B) allele for dark brown fur. Dark brown fur allele would always express itself over the recessive allele, (b).
For a mouse that has dark brown fur, the possible genotype it could have is either (BB) => 2 dominant allele, or (Bb) => 1 dominant allele and a recessive allele. The dominant allele would always express itself even in the presence of the recessive allele.

The enzyme carbonic anhydrase catalyzes the formation of carbonic acid from carbon dioxide and water. Imagine that you have two sealed tubes with carbon dioxide gas above a buffer containing water and carbon dioxide. One tube has carbonic anhydrase and the other does not. After 24 hours, both tubes are at equilibrium. Which statement below accurately describes the conditions in the tubes?
A. The tubes will have equal concentrations of carbon dioxide and carbonic acid
B. The tube with carbonic anhydrase will have a lower concentration of carbon dioxide and a higher concentration of carbonic acid than the tube with any enzyme.
C. The tube with carbonic anhydrase will have a higher concentration of carbonic acid than the tube with any enzyme, but the concentration of carbon dioxide will be the same in both tubes.
D. The tube with carbonic anhydrase will have a higher concentration of carbon dioxide and a lower concentration of carbonic acid than the tube with any enzyme.
E. It is not possible to determine the relative concentrations of the products and reactants without more information about carbonic anhydrase, such as the Km.
Answer:
The correct option is B: "The tube with carbonic anhydrase will have a lower concentration of carbon dioxide and a higher concentration of carbonic acid than the tube with any enzyme."
Explanation:
Since there is an enzyme present that catalyzes (i.e., speeds up) the reaction, it will make the process more efficient and thus, the conversion of carbon dioxide to carbonic acid will occur quicker as compared to the tube that does not have the anhydrase enzyme included in it. More carbonic acid would mean lower concentration of carbon dioxide.
