Compare the movement of oxygen and carbon dioxide across the cell membrane
Answers
"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."

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?
Answers
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.
How do the adaption of angiosperms make them well suited for land
Answers
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.

Any physical change just changes the shape/form of an object (like cutting wood or blow drying hair). These are pretty reversible and they don’t change the chemical structure.
Chemical changes change the actual properties of the object, so like burning bread and acid rain!

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 .
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.

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]
