Answer:
Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.
Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.

True or false: All herbivores are autotrophs.
Answer:
false
Explanation:
Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, which eat autotrophs, are the second trophic level. Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level.

Explain what happens to a cell as it enters the cell cycle and goes through the process of
MITOSIS. Tell what happens to the cell at each part of the cell cycle starting at
Interphase, then the stages of Mitosis (PMAT) and ending at Cytokinesis. (This should be
a longer response than one sentence!!)
Answer:
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Explanation:
During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

What would happen to food chains if all the plants died out ?justify your answer.
Answer: there would be no way for energy to enter the food web, and the ecological community would collapse.
Explanation:
everything would die because its a domino effect
Answer:
There would be no way for animals to get the energy they would need so all of the animals would get sick, and if other animals ate them they would get sick and the food chain would start dying.

How would the fact that a species like the Florida panther "requires large territories" make it vulnerable to extinction?
Answer:
Continued human development and natural resource abuse lessen the amount of wilderness, affecting the Florida panther particularly negatively due to its requirement for large territories.
Answer:
With the continuous expantion of humanity and society, wild territory is becoming smaller and smaller. The more needs an animal requires, the harder it will be for that animal to survive.
Explanation:
I would like to note that I am dissatisfied with the answer you gave nineteen different questions (including my own); And I quote "Sorry don’t know just trying to get points". These are the words that were used, and it is impossible for me to believe that you would be jumping up and down for joy if this was the answer you got on your questions. Now, I could have done the same to you for revenge (trust me, the thought passed my mind), or, I could show you what it is like to act mature. Again, I feel sorry that you fill your days with letting others down when they need it. I hope my answer helps you more than your answer helped me.
And to any other people who may see this answer, if you do the same thing as this user, please stop. It makes others feel like they don't mean anything to anybody else. This behavior is not a habit, it's a disease. It makes me incredibly upset, so please stop the unnecessary fake apologies.
Thanks.

Put the phases of cell division (sex cells ) in order there are 12
Answer:
Prophase I, prometaphase, metaphase I, anaphase I, telophase I, and cytokinesis, interphase, prophase II, prometaphase II, metaphase II, anaphase II, telophase II, and cytokinesis.
Explanation:
Prophase I, prometaphase, metaphase I, anaphase I, telophase I, and cytokinesis, interphase, prophase II, prometaphase II, metaphase II, anaphase II, telophase II, and cytokinesis are the 12 phases of cell division that occurs in the sex cells of human body. These double phases allow the sex cells to produce four daughter cells from a single parent cell but the chromosomes number is half in each daughter cell.
Period 6 2-25 What percent of offspring from two heterozygous parents will have the dominant phenotype? William Brown. Feb 24 100 points please help
Answer:
75%
Explanation:
If both parents are heterozygous (Ww), there is a 75% chance that any one of their offspring will have a widow's peak (see figure). A Punnett square can be used to determine all possible genotypic combinations in the parents. A pedigree that depicts a dominantly inherited trait has a few key distinctions.

What would happen to the food that someone ate if they didnt have the digestive enzymes they needed
Answer:
The digestive system is my favorite system! Without it you would not survive. Our digestive system is how we break down food into nutrients that feed our cells and give us energy to move, talk, grow, think, reproduce, and all the other crazy things that humans do.
Although each of the parts of the digestive system has specific and important functions, shockingly, you can survive without some of the parts. For example, morbidly obese individuals can have their stomach entirely removed in a procedure called a gastric bypass. In this surgery, the small intestine is linked directly to the esophagus thus “bypassing” the stomach. You can also live without your appendix. In fact, it sometimes negatively impacts health as it can become infected (have you ever known someone who had their appendix burst?). The appendix was thought to be a “vestigial organ” meaning that at one point in evolutionary history, we humans had a need for it, but now we don’t; however, there is recent evidence that the appendix is an important hotbed for beneficial bacteria that help us digest food.
Explanation:
I hope this helps! Brainliest is always appreciated!
Answer:
They wouldn't be able to digest the food. It wouldn't break down like it's supposed to with the digestive enzymes.
