How does being hydrophobic affect protein folding?

Answers

Answer:

The hydrophobic effect is considered to be the major driving force for the folding of globular proteins. It results in the burial of the hydrophobic residues in the core of the protein. It is exemplified by the fact that oil and water do not mix and was described well by G. S. Hartley in 1936 .

Which is most likely a source of air pollution?
littering
CFCs
oil spill
runoff

Answers

The answer to this question is CFSs

Air pollution is defined as the pollution of the air and its surroundings due to air pollutants where chlorofluorocarbons (CFCs) are the most common source of air pollution. So, the correct option is B.

What are Chlorofluorocarbons?

Chlorofluorocarbons (CFCs) are defined as non-toxic chemicals containing chlorine, fluorine and carbon that are extensively used in the manufacture of refrigerants, foams, sprays, etc. Chlorofluorocarbons destroy the Earth's protective ozone layer by affecting its ability to shield harmful UV rays from the Sun, which is why they are banned because of their dangerous effects on ozone.

CFCs are emitted which get accumulated in the earth's atmosphere causing greenhouse effect which causes melting of ice and rise in sea level leading to rise in temperature.

Therefore, the correct option is B.

If logging operations are conducted on a hillside near a river, the operations will most likely -
A. increase the number of organisms in the river
B. increase the amount of sediment in the river
C. decrease the rate of runoff from the hillside
D. decrease the amount of erosion along the hillside

Answers

Answer:

D. decrease the amount of erosion along the hillside

Explanation:

When logging operations are conducted on a hillside near a river, the operations will decrease the amount of erosion along the hillside because the tree's root hold soil particles and does not allow them to erosion. We can see in many region that there is presence of vegetation on the bank of river or stream in order to prevent erosion of soil so that's why we can say that logging operations causes decrease erosion along hillside.

A particular single celled organism is it radiant energy to fix carbon as yours does organism generate ATP by breaking down sugars through a process that uses oxygen based on this information how should this organism be classified

Answers

The autotrophs are the organisms that uses sunlight (radiant energy) to perform the process of photosynthesis to fix carbon in the form of sugars. They generate ATP by breaking down the sugar using oxygen, which means they perform cellular respiration. This makes the organism aerobic autotroph.

The diagram below represents a reproductive process.Which reproductive process is represented by the diagram?

Answers

Answer: Asexual Reproduction

Explanation:

The diagram below represents meiosis a reproductive process, used for the development of gametes, hence option B is correct.

What is meiosis?

It is the cell cycle stage in which the chromosome number of the parent cell gets reduced in the daughter cell, it is used to produce haploid gametes.

While mitosis is the cellular stage in which diploid organisms are used to increase the cell numbers of somatic cells it does not generally occur in germ cells of humans. As similar to mitosis asexual reproduction also produces identical cells.

Meiosis proceeds in the germ cell, where diploid organism produce haploid cells which are fertilized to form the diploid zygote.

Therefore, the given diagram in the question represents the meiosis reproductive process.

The variable h represents the number of hours spent doing yard work and the variable d represents the amount of money earned how many hours spent doing yard work and the variable d represents the amount of money earned how many hours in all will it take Whitney to earn 15$

Answers

Answer:

[tex]4\frac{1}{11}[/tex] hours

Explanation:

Given

See attachment for graph

First, we determine the equation of the graph.

Pick any two points from the graph

[tex](h_1,d_1) =(18,168)[/tex]

[tex](h_2,d_2) =(36,366)[/tex]

Calculate the slope (m)

[tex]m = \frac{d_2 - d_1}{h_2 -h_1}[/tex]

This gives:

[tex]m = \frac{366 - 168}{36 -18}[/tex]

[tex]m = \frac{198}{18}[/tex]

[tex]m = 11[/tex]

The equation is then calculated as:

[tex]d = m(h - h_1) + d_1[/tex]

This gives:

[tex]d = 11(h - 18) + 168[/tex]

Open bracket

[tex]d = 11h - 198 + 168[/tex]

[tex]d = 11h-30[/tex]

So, the number of hours to earn $15 is:

[tex]d = 11h-30[/tex]

[tex]15 = 11h -30[/tex]

Collect like terms

[tex]11h = 15 + 30[/tex]

[tex]11h = 45[/tex]

Solve for h

[tex]h = \frac{45}{11}[/tex]

[tex]h = 4\frac{1}{11}[/tex]

what directs the changes that occur in allele frequency
a. natural selection
b. random mutations
c. hox genes

Answers

Answer:

I think it's b - random mutations... >3

A change in allele frequency is directed by natural selection. So the correct answer is option A.

What is meant by allele frequency?

The allele frequency (also known as gene frequency) refers to the frequency at which a particular allele appears in a population. The term evolution in population genetics refers to a variation in the frequency of a particular allele within a population. The frequency ranges from 0 (zero alleles present in no individuals) to 1 (all alleles present in all individuals). The gene pool refers to the sum of all alleles at all the genes in a population.

Natural selection affects the phenotype, or observable characteristics, of an organism. Phenotype is usually largely determined by genotype (the number of alleles, or versions of genes, that an organism carries).

When the phenotype produced by specific alleles helps an organism survive and multiply better than its neighbors, natural selection can spread the beneficial alleles from generation to generation – in other words, it causes microevolution.

by the year 2020. Which BEST explains how

A. by gradually making up more available energy

B. by using resources faster than they can be

C. by changing how matter cycles through an

D. by increasing the variety of ecosystems that are

Answer:

by using resources faster than they can be

replaced

Explanation:

As population of the world continues to grow, there is greater demands for resources which are obtained from the environment such as crude oil for energy, solid minerals for various applications, wood for furniture etc.

Demand for these materials increase exponentially as population increases thus they are extracted at a faster rate than nature can replace them. This will eventually harm the environment on which humans depend as population increases.

A mechanism by which cancer cells can evade an immune response involves an alteration in the amount of MIC on the cell surface by _________. Group of answer choices cleavage of MIC at the cell surface by a protease decreasing the level of MIC transcription switching from a transmembrane form of MIC to a secreted form cytosolic degradation of MIC in proteasomes alternative mRNA splicing resulting in a truncated form of MIC that is no longer able to bind to NKG2D

Answers

Answer:

cleavage of MIC at the cell surface by a protease

Explanation:

The immune system refers to a complex network of cells and proteins that function to eliminate potentially tumorigenic cells on a daily basis. However, cancer cells show mechanisms in order to escape immune responses. MHC class I chain-related proteins A and B (MICA and MICB) are expressed in normal and tumorigenic cells where they act as ligands of the NKG2D receptor. The expression level of these proteins (MICA and MICB) is finely regulated by the activity of metalloproteinases (i.e., by protease-mediated cleavage), but this mechanism is altered in cancer cells. Recently, drug therapies that stimulate NKG2D mediated tumor destruction by reducing the cleavage of MICA and MICB from the surface of cancer cells have been developed.
