Certain cells need to absorb a lot of materials, such as the cell of the small intestine that reabsorbs the digested foods into the blood. These cells have external growth that facilitates the reabsorption by increasing the surface area.
What is the intestine?The intestine is divided into two parts, such as the small intestine and the large intestine, The small intestine is responsible for digestion, while the large intestine is responsible for fecal excretion. The enzymes are secreted, complete digestion happens in the small intestine, the digested food is reabsorbed into the blood, and the cells that carry out the reabsorption have external grooves called villi. These villi increase the surface area of the small intestine so that more absorption can occur and cells get enough nutrition for cellular metabolism.
Hence, Certain cells need to absorb a lot of materials, such as the cell of the small intestine that reabsorbs the digested foods, which has villi as a special feature of the cell.

acid rain removes nutrients from soil.
Increased ozone levels slow plant growth.
Increased carbon dioxide levels support plant growth.
Increased nitrogen dioxide levels provide nutrients for plants.
Answer:
I'd Say A because it talks about slowing down the plants and removing stuff from the soil. Fire and smoke only cause problems for the surrounding area by blocking the sun and burning the ground, removing materials plants need for life. Then when it rains all the acidic stuff kills the ground as well.

1.)
Inhaled air includes oxygen, which travels through the thin lining of the air sacs to reach the blood vessels. This is referred to as diffusion. The bloodstream then transports the oxygen in the blood throughout the body, reaching every cell. When oxygen enters the circulation, carbon dioxide leaves.
2.)
The word "glucose" comes from a Greek word that means "sweet." It's a type of sugar that originates from the foods you eat and is converted into energy by your body. Because it travels via your circulation to your cells, it's termed blood glucose or blood sugar. Insulin is a hormone that transfers glucose from the circulation to cells for storage and usage as fuel.
3.)
Breathing not only gives your body the oxygen it needs, but it also gets rid of trash like carbon dioxide. Your blood transports carbon dioxide to the capillaries that surround your alveoli to be expelled. Carbon dioxide flows from the alveoli to the lungs, where it is exhaled out of the body.

True is correct! =)

There are no known effects and scientific evidence that proves GMOs are harmful to humans. GMOs have edited genes that help them to be resistant against a myriad of diseases, environmental conditions, and change "ugly" traits (ie. shortness, too skinny fruit, etc). The process of editing genes is like the recombination of DNA by human intervention. You edit out what's ugly and reinforce what is needed without changing the physical make-up of the organism.
✪ Example ✪
Corn is very known to have a GMO. It also has different varieties that are products of selective breeding, a type of narrowing down the best traits from two pure-bred individuals.

Answer:
Speciation occurs when two or more populations become so genetically distinct that they no longer interbreed with one another.
Explanation:
When Arizona's Grand Canyon formed, squirrels and other small mammals that had once been part of a single population could no longer contact and reproduce with each other across this new geographic barrier. They could no longer interbreed. The squirrel population underwent allopatric speciation.

The internal structure of a leaf. Where does most photosynthesis occur?
How will the ice water mix with the salty water? Write your hypothesis below.
Answer:
See below.
Explanation:
The actual reason that the application of salt causes ice to melt is that a solution of water and dissolved salt has a lower freezing point than pure water. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on.
Answer: I think that the ice will go slower because salt slows down the rate of which Its melt, so the ice would last longer

What trend do you notice about the relative amount of carbon dioxide in the atmosphere over time? And for oxygen? What factors could cause changes in the carbon dioxide and oxygen gas levels of Earth’s atmosphere?
Answer:
The proportion of oxygen went up because of photosynthesis by plants. The proportion of carbon dioxide went down because: it was locked up in sedimentary rocks (such as limestone) and in fossil fuels. it was absorbed by plants for photosynthesis.
Explanation:
Due to plant photosynthesis, the amount of oxygen increased. Because carbon dioxide was trapped in sedimentary rocks (like limestone) and fossil fuels, its percentage decreased. Plants utilized it for photosynthesis.
What is photosynthesis?Carbon dioxide concentrations CO2 are expected to rise, which will raise serious concerns about how plants react to the gas. Increased photosynthesis results from elevated CO2 in plants, which increases biomass and carbohydrate production.
It varies both within and across species as to which organ receives the extra carbs. There is currently a paucity of knowledge regarding how the greater concentration of carbohydrates generated under rising CO2 affects the sugar sensing and signaling pathways of plants.

Explain why you think blood vessel radius can have a larger effect on the body than changes in blood vessel length (use the blood flow equation).
Here is your Answer:-
✓ While the flow rate is proportional to the length, the flow rate is proportional to the fourth power of the radius.
Blood vessel da\iameter affects the blood pressure in body because it creates vasoconstriction and vasodilation, hence blood vessel radius has a larger effect on the body.
What is the effect of blood vessel radius in the body?Blood flow increases considerably when the radius of the vessel lumen grows (a process known as vasodilation), and vice versa.
Vasodilation causes the blood vessel width to increase, making it easier for the heart to pump blood into it. However, such a blood artery has lower blood pressure than a smaller diameter or vasoconstriction blood channel.
Arterioles have the greatest increase in resistance and the greatest drop in blood pressure. Arteriole constriction increases resistance, resulting in a drop in blood flow to downstream capillaries and a bigger decrease in blood pressure.
Therefore due to blood pressure in body blood vessel radius affects larger.
