Your skin cells have 46 chromosomes. After they complete the cell cycle, how many chromosomes will be in the daughter cells? Explain.
Answer:
46
Explanation:
The skin cells with 46 chromosomes will each produce daughter cells with 46 chromosomes after they complete the cell cycle.
The skin cell is a vegetative cell that can only divide through mitosis. Mitosis is also referred to as equational division during which a cell produces two daughter cells that are both genetically and phenotypically similar to the parent cell.
During the cell division, at the anaphase stage to be precise, the chromosomes are separated into sister chromatids and sister chromatids of the same chromosomes move in the opposite direction to the poles of the cell before the cytoplasm of the mother cell divides to produce two independent daughter cells. Each chromatid in the new daughter cells then goes ahead to become a complete chromosome with two sister chromatids.
Hence, at the end of the cycle, each daughter cell ends up having the same 46 chromosomes as the parent cells.

What happens to light energy when it is absorbed by a leaf?
Explanation:
In photosynthesis, chlorophyll absorbs energy to transform carbon dioxide and water into carbohydrates and oxygen. This is the process that converts solar energy to a form that can be utilized by plants, and by the animals that eat them, to form the foundation of the food chain.

Disturbances in Ecosystems Quick Check
What is the function of a top predator in an ecosystem?(1 point)
-It helps increase the number of prey.
-It creates imbalance in the ecosystem.
-It increases the food for other predator species.
-It maintains other populations.
Which is considered a top predator in the ocean?(1 point)
-a sea lion
-a bird
-a small whale
-a shark
What happens to an ecosystem during normal seasonal flooding?(1 point)
-The biodiversity of the area stays the same.
-The biodiversity of the area reaches equilibrium.
-The biodiversity of the area decreases.
-The biodiversity of the area increases.
How is the impact of seasonal flooding different from damming a river?(1 point)
-Seasonal flooding is not considered an ecological disturbance like damming.
-Seasonal flooding does not impact biodiversity for as long term as damming.
-Seasonal flooding helps balance biodiversity, but damming does not.
-Seasonal flooding increases biodiversity, but damming does not.
Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?(1 point)
-No, because it would not create large-scale changes in the environment.
-Yes, because any slight change in temperature is considered a disruption.
-Yes, because such a change could have a large-scale impact on wildlife.
-No, because increases and decreases in average temperatures are normal.
Please help and thank you.
Answer:
D / D / D / B / C
Explanation:
I just took the quick check myself, got all of them right :)
1 ) Top predators do not increase the number of prey, neither do they create imbalance or increase the food for other predator species. This is common knowledge, so ruling those out you are left with D. As they do in fact maintain the rest of the food chains populations.
2) A top predator in the ocean is a shark. Of course some might mistake a small whale to be a top predator, but sharks are actually known to hunt whales- the small ones anyway. A sea lion fish or a bird wouldn't exactly be a candidate for the top of the food chain either.
3) During seasonal flooding, to an area such as a river, water gets added to the existing pool, and many biotics and abiotics take this to their advantage. As a result- biodiversity actually increases during these times, but once season flooding is over it goes back to being the same.
4) The impact difference of seasonal flooding from damming a river is actually quite big. Seasonal flooding is.. well.. seasonal.. while damming for the most part is permanent, or will be there for much longer time span than season flooding is. Seasonal flooding increases biodiversity, but damming does not. This is becuase of the long term increase of water, the environment has to readapt, as plants that were once there drowned, and the known species most likely ran off to find better environment. Here it takes a while but eventually new abiotic and biotic species adapt and reclaim the dammed area of the environment.
5) Yes, a long term increase in the average temperature would disturb the ecosystem. Even if it's for a little bit, it's still something the environment wouldn't be used to, meaning the plants and animals there would have to learn to adapt for the time being- even if its temporary.
1: It maintains other populations
2: A shark
3: The biodiversity of the area increases
4: Seasonal flooding does not impact biodiversity for as long term as damming.
5: Yes, because such a change could have a large-scale impact on wildlife.

3. What is the kingdom that contains single-celled organisms that live in extreme environments?
A. plantae
B. bacteria
C. protista
D. archaea
The kingdom that contains single-celled organisms that live in extreme environments is archaea. The correct option is D.
What are single-celled organisms?A single cell makes up a unicellular creature, also referred to as a single-celled organism, as opposed to a multicellular organism, which is made up of numerous cells. Similar to Eukarya, Archaea have RNA polymerases that are more complicated than those of bacteria.
Archaea do not have peptidoglycan in their cell walls, in contrast to bacteria. The membrane lipid bonding of archaea differs from that of bacteria and eukarya.
