Observation of Diffusion Rate in Relation to Cell Size
As you have observed, cells are small. Consider your little toe: it is made of about 2-3 billion
cells! A newly-made cell will grow, but once it reaches a certain size it will divide to form two
new cells rather than growing bigger. Why is this? Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions? Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? In this lab, we will investigate this question using model cells.

Explanation:
new cells rather than growing bigger. Why is this ?
There are two main reasons why cells divide rather than continuing to grow larger and larger: ... If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Cell Division. Cell division is the process by which cellular material is divided between two new daughter cells.
Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? again The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

How would an organism most likely respond to extremely cold temperatures? (4 points)
A. Blood vessels would constrict to reduce heat loss through negative feedback.
B. Blood vessels would dilate to transfer heat to more areas of the body through positive feedback.
C. Cold receptors would signal the body to retain heat through positive feedback.
D. As the organism uses energy, body temperature would decrease through negative feedback.
Answers
Explanation:
the answer is A..........
An organism most likely would respond to an extremely cold temperature as the blood vessels would constrict to reduce the heat loss through the negative feedback. Thus, the correct option is A.
How does an organism adapt to cold temperature?Adaptations are the changes in the body of a living organism which help them to survive better in a particular set of environmental condition such as hot temperature, cold temperature, etc.
In cold temperature, Shivering is an adaptation in which the nerve impulses are sent by the hypothalamus of the brain to the skeletal muscles to bring about rapid contractions which generate heat and this helps the body in staying warm. Shivering therefore helps an organism in raising the body temperature. Increase in the metabolic rate, the liver produces extra amount of heat in order to raise the temperature of the body.
An organism most likely respond to cold temperature as the blood vessels constrict to reduce the heat loss through negative feedback.
Therefore, the correct option is A.

b. the DNA of two alleles must be almost identical. since the trait is the same. But the effect of the allele may be very different!
c. in humans, for every trait we can only have two alleles. but that trait can be controlled by many alleles. there are no limits on how many alleles can control a trait.
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
e. if humans were diploid we would only have one allele per trait
Helpppp pleaseee
Answers
Answer:
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
Explanation:
Being diploid means humans carry two sets of chromosomes. Since we have both dominant and recessive gene types, humans can mask the effect of recessive alleles since the dominant trait will be seen in the phenotype or genotype since it is a dominant gene. The effect of the recessive allele will show up only if both diploid genes are recessive.
Structural and behavioral adaptations affect the reproductive success of plants and animals.
A. True
B. false
Answers
Structural and behavioral adaptations can indeed impact the reproductive success of plants and animals. Adaptations are traits or behaviors that help organisms survive and reproduce in their environment. The statement is true.
Structural adaptations refer to physical features or characteristics that organisms possess. For example, plants may develop specialized structures like flowers, fruits, or seed dispersal mechanisms that enhance their reproductive success. Animals may have specific anatomical features like camouflage, protective shells, or specialized reproductive organs that increase their chances of successful reproduction.
Behavioral adaptations, on the other hand, involve actions or behaviors that organisms exhibit. These behaviors can include courtship rituals, mating displays, migration patterns, or parental care. Such behaviors help attract mates, establish territories, protect offspring, and ensure the successful transfer of genetic material.
Therefore, the statement is true.

C. It will decrease the percentages of almond and apple crops because lesser numbers of honey bees are available for pollination.
Explanation:
The decrease in honey bees population will affect the ecosystem by decreasing the percentages of almond and apple crops which will lead to lesser numbers of honey bees available for pollination. Almonds and apple crops rely on honey bee colonies for pollination. So, a decrease in the population of honey bees will have an adverse effect on the availability of the crops and food supply. For most variety of almonds, they do not wind pollinate but require cross-pollination in order to produce nut. Other crops that rely on honey bees are watermelon, cucumbers and cherries.

By moving warm water and precipitation from the equator to the poles and cold water from the poles back to the tropics, ocean currents function much like a conveyor belt, hence option B is correct.
What are Earth's ocean currents?Global climate is regulated by ocean currents, which also assist to balance out the unequal distribution of solar energy hitting Earth's surface.
Sunlight energy is absorbed and stored by the ocean, which controls the temperature of the Earth's atmosphere. More than half of the solar energy that reaches Earth's surface is absorbed by the ocean, which both absorbs and releases heat more slowly than land.

Which statement describes the relationship between plants, animals, and the carbon cycle?

O Animals fix carbon and release oxygen, and plants release carbon and use oxygen.
Animals fix carbon through respiration, and plants fix carbon through photosynthesis.
Plants use carbon when they decompose, and animals release carbon when they decompose.
Answers
Answer:
Plants use carbon and release oxygen, and animals release carbon and use oxygen.
Explanation:
The statement that accurately describes the relationship between plants, animals, and the carbon cycle is:
Plants use carbon and release oxygen, and animals release carbon and use oxygen.
Why do plants use carbon and release oxygen?Plants play a crucial role in the carbon cycle through the process of photosynthesis. They absorb carbon dioxide (CO2) from the atmosphere and use it, along with sunlight and water, to produce carbohydrates and release oxygen as a byproduct. This process helps to remove carbon from the atmosphere and convert it into organic compounds.
On the other hand, animals (including humans) obtain energy by consuming plants or other animals. During respiration, animals take in oxygen and release carbon dioxide as a waste product. This carbon dioxide is then released back into the atmosphere, where it can be used by plants for photosynthesis.
Therefore, plants contribute to the reduction of atmospheric carbon dioxide levels by using carbon during photosynthesis and releasing oxygen, while animals contribute to the carbon cycle by releasing carbon dioxide during respiration and utilizing oxygen.
