How does being hydrophobic affect protein folding?
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 .
what directs the changes that occur in allele frequency
a. natural selection
b. random mutations
c. hox genes
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.

How do the adaption of angiosperms make them well suited for land
Answer:
They have adapted to land, adding features such as embryo retention, a cuticle, stomata, and vascular tissue.
Explanation:
Plants haven't always been on the surface of the earth. Life was restricted to water for a long time. The first plants arose from green algae that resembled the Chara in the image above. Bacteria living in water were the earliest photosynthetic creatures. Soon, as algae evolved, and water drifted away, plants were found on land. Land plants had adaptations that would help their future generations.

cancer drug Vinblastine interferes with the
synthesis of microtubules. Which process does
Vinblastine interfere with during the cell mitosis?
Answer:
The correct answer is - disrupting microtubule assembly and proper formation of the mitotic spindle and the kinetochore.
Explanation:
Vinblastine is known for treating cancer cells by sending them to apoptosis. It interferes with the synthesis of microtubules. It binds to the microtubular proteins of the mitotic spindle that causes disrupting microtubule assembly.
It also prevents from proper formation of the mitotic spindle and the kinetochore which is essential to separating chromosomes during anaphase. They arrest mitosis and cause cell death.
4. The human population has experienced unchecked growth for the past 200 years. What does "unchecked" mean? A. Slow b. At a steady rate c. Unrestrained d. Dangerous
Answer:
B
Explanation:
The correct option would be B
The human population experiencing unchecked growth for the past 200 years does not mean that there were no restraining factors that limit the population. Factors such as death, competition for resources, diseases, etc., were still present.
Despite the limiting factors, the population has been growing. Hence, the correct word to replace 'unchecked growth' would be 'at a steady rate'.
Slow and dangerous really have nothing synonymous with unchecked growth.
The correct option is, therefore, B.

Definition of Salt Water
(Impact on Weather)
The thickness of seawater is an element of saltiness and temperature, Lagerloef clarified. Saltier water is heavier and will sink further in the sea, where it joins flows that course water all throughout the planet. ... Stable salt densities in the seas keep the world's environment in balance, researchers accept.
hope this helps:)
Answer:
Salt weathering or Salt Weather is a form of mechanical or physical weathering of rock. ... The salt derives from an external source (capillary rising ground water, eolian origin, sea water along rocky coasts, atmospheric pollution). Salt weathering is favoured by dry conditions, such as are found in warm and cold (arctic) arid climates.

Census data show that the human population doubled from 2.65 billion in 1953 to 5.3 billion in 1990. If it continues to double at this rate, the human population could reach 10 billion by the year 2020. Which best explains how this rate of human growth can harm the environment on which humans depend?
The question is incomplete, the complete question is;
Census data show that the human population
doubled from 2.65 billion in 1953 to 5.3 billion
in 1990. If it continues to double at this rate,
the human population could reach 10 billion
by the year 2020. Which BEST explains how
this rate of human growth can harm the
environment on which humans depend?
A. by gradually making up more available energy
B. by using resources faster than they can be
replaced
C. by changing how matter cycles through an
ecosystem
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.
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$
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]

Compare the movement of oxygen and carbon dioxide across the cell membrane
"As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. ... Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell."
