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
Answers
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.

In the picture, there is a dark moth and light moth on each tree. If all the trees are dark colored
(without lichens) like the tree on the right, which moth is more likely to survive? DS
(1 Point)
Answers
Answer:
If all the trees are dark-colored (without lichens) like the tree on the right, the moth that would most likely survive longest is the dark-colored moth.
Explanation:
This is because of natural selection (which means "A process in which individual organisms or phenotypes that possess favourable traits are more likely to survive and reproduce: the differential survival and reproduction of phenotypes.") The dark-colored moth is best adapted to its surroundings compared to the light-colored moth, and it will survive the longest (of the two) according to this definition of natural selection.

how does the gravitational force between two objects change if the distance between the objects increases?
Answers
Answer:
YES
Explanation:
As g ∝ 1/d² between two two components, further potential difference would result in lower gravitational pull. So the influence of gravitational pull among them also reduces as two things are isolated from the others.

15. Which of the following statements is false? A) scientists study rock layers and fossils when developing the geological time scale. B) according to the law of superstition the youngest rock layers are at the bottom. C) The oldest known rocks on earth are approximately 4 million years old. D) earth is constantly changing.
Answers
Answer:
B
Explanation:
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first)
Hope this helps :)
The statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.
What are the fossils?The fossils are the preserved materials of the animals and plants, such as the skeleton, teeth, bones, imprints, and other parts stored in the different layers of the earth. These fossils are preserved in natural ways, not by humans, and they are helpful for the study of the different animals because some fossils give the idea of the connecting links, and they give the idea of the animals' living conditions in the early time.
Hence, the statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.

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
Answers
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.
