Why must cells divide to stay small or change shape to reduce volume?
O To diffuse substances from an area of higher to lower concentration
To ensure the cell is able to obtain nutrients or remove wastes.
To reduce surface area of the cell for quick movement.
O To move water molecules from areas of high to low pressure
Answer:
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.
Explanation:
Answer:
To ensure the cell is able to obtain nutrients or remove wastes.
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 That is why cells are so small.

Which of the following statements is true as the moon goes from new moon to full moon
phase? Choose all that apply.
We see more of the lighted side of the moon.
We see less of the lighted side of the moon.
The time it takes to go from new moon to full moon is 2 weeks.
The time it takes to go from the new moon to full moon is 4 veeks.
Answer:
We see more of the lighted side of the moon because it is growing, so we see more
The time it takes to go from new moon to full moon is 2 weeks, because it takes a whole month (4 weeks) to go from new moon to full moon to new moon

In the autumn, many birds will collect seeds and then hide them in various caches throughout their habitat. The birds will guard their caches
from other birds, and move the caches if they start to dry out. These caches provide a food source for the birds during the water. What is an
ablotic factor that contributed to the evolution of this set of behaviors?
OA cold winter climate
OB competition with other birds for space
OC being preyed upon by larger birds
OD. limited food availability
Answer:
OA Cold winter climate
Explanation:
Other answers are biotic (living) factors, but cold winter climate is abiotic (non - living).

Which one of the following is the name for the way cells divide in asexual reproduction?
Twins
Mitosis
Meiosis
Generation Square
Answer:
Mitosis
Explanation:
When a eukaryotic cell divides asexually, the nucleus and its genetic contents must divide too, in a process called mitosis. Both haploid (n) and diploid (2n) cells can divide asexually, at which time their nuclei divide mitotically.
How would the way I dress be impacted if photosynthesis stopped tomorrow?
write half a page for full credit
thank you you're a lifesaver
Answer:
i dont want to do so much writing but i guess i will help
Explanation:
If photosynthesis came to an abrupt end, most plants would die within short order. Although they could hold out for a few days -- or in some cases, a few weeks -- how long they lived would largely be a factor of how much sugar they had stored within their cells. Large trees, for example, may be able to soldier on for several years — perhaps even a few decades — because of their energy stores and the slow rate of use. However, the majority of plants would meet a withering end, and so would the animals that rely on them for nourishment. With all the herbivores dead, the omnivores and carnivores would soon follow. Although these meat-eaters could feed on all the carcasses strewn about, that supply wouldn't last more than a few days. Then the animals that temporarily relied on them for sustenance would die.
Meiosis occurs only in germ cells

What would happen if cytokinesis did not occur?
Answer:
Cytokinesis takes place in both meiosis and mitosis and performs the separation of he cell in half and form one nucleus into each daughter cell.
If cytokinesis did not happen, it will from multinucleated cells which means that their will be multiple nuclei in single cell and cell will not get separate in half, and no new daughter cells will form.
Each "word" in the mRNA language consists of how many letters?
Answer:
3 letters
Explanation:
The "letters" of the alphabet are grouped into "words" of three letters each. On the mRNA molecule each "word" of three letters is called a codon. a single codon specifies, or "codes for", a single amino acid.

In the Punnett square below what would be the genotype for the organism represented by box 2?
1.) bbss
2.) BbSs
3.) bbSs
4.)Bbss
Answer:
bbss
Explanation:
mitochondria is the powerhouse of a cell
The genotype for the organism is represented by box 2 - 1.) bbss.
Punnett square is a way to find the genotype of any trait either monohybrid or more than one allele. To predict the outcome of breeding experiments where one trait with two boxes and two traits are being followed and the Punnett square is larger, with sixteen boxes.
Each side has gametes, representing alleles they have, produced by each parent.Each box shows the zygote that has a genotype combination of the gametes.for instance, here bs is fused with bs which form the zygote that contains the genotype bsbs.Thus, The genotype for the organism is represented by box 2 - 1.) bbss.

Earth is composed of layers of material with different properties. Which
of the following is most likely to contain material that is in constant
motion?
So
Answer:
mantle
Explanation:
A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density. All terrestrial planets (including Earth), a number of asteroids, and some planetary moons have mantles.
