Answer:
The mass (increasingly bigger size) of a tree comes from the soil. Which makes sense, right? After all, we are taught that plants need soil (enhanced “dirt”) to grow. According to Michigan State University Extension, problems typically arise when asked to explain why there isn’t a big hole around a tree. If the tree is using soil, then there must be less soil around it. But studies show virtually no difference in the amount of soil in a pot when a seed is planted from the amount of soil in the same pot when the plant from that seed is harvested. So where does the mass come from?
The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun’s energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water. Yes, the carbon from carbon dioxide in the air we breathe out ends up in “food” molecules (called glucose) each of which contains 6 carbon atoms (and 12 hydrogen atoms and 6 oxygen atoms).
Explanation:
So the mass comes from the soil but its primarily carbon. HOPED THIS HELPED YOU!

A prokaryotic cell is...
A. A cell that does not contain DNA
B. A cell that has multiple organelles
C. A cell that does not contain a nucleus
D. A cell found in plants, animals, fungi, etc.
Answer: A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid

How does having genes on many chromosomes, rather than on just one chromosome, increase genetic variation among offspring?
Answer:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. ... A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes
Explanation:
Due to the possibility of genetic material being recombined and shuffled during meiosis, having genes on several chromosomes as opposed to only one chromosome enhances genetic variety among kids.
What is genetic variation among offspring?At locations known as chiasma, the chromosomes overlap. The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.
The chromosomes align in pairs and cross over during the meiotic process to exchange genetic material. This process results in novel gene pairings on the chromosomes, which can result in the birth of kids with distinctive combinations of features.
Therefore, the possibility of genetic material being recombined and shuffled during meiosis increases genetic variation among offspring.

Based on the results of this study, what questions remain unanswered? How can these questions guide future research?
Answer: One of the biggest questions is, Can we replicate these results in other plants? So, there needs to be more research to determine whether this technique is effective in food crops. It’s not known what the protein PsbS does, even though it seemed to enhance plant growth. There should definitely be more research to find out how this protein is linked to plant growth and whether boosting this protein will affect growth in other types of plants. The researchers also noted that there are numerous other ways to make photosynthesis, and there are more than 100 chemical reactions involved in the process. Investigating other possibilities might be the key to improving crop yield in a wide variety of crops.

Describe the ten percent rule, and explain what percentage of energy a dolphin would have after it ate a fish, that ate an insect, that ate some grass.
Answer:
The ten percent rule, also known as the law of ecological tithe, has to do with the effective transfer of energy that occurs at different trophic levels, corresponding to the use of one tenth of the energy from the immediate previous level.
Explanation:
The 10 percent rule was established by the english naturalist Charles Sutherland Elton, indicating that the transfer of energy from one trophic level to another is only 10 percent. This means that the level immediately above can only use one tenth of the energy produced by the level before it.
What percentage of energy a dolphin would have after it ate a fish, that ate an insect, that ate some grass?For example, if we say that grass produces 10000 Kcal, the insect that consumes it (primary consumer) will be able to use 1000 Kcal, the fish that consumes insects 100 Kcal and the dolphin that consumes the fish only 100 Kcal.
Grass → Insect → Fish → Dolphin
10000 1000 100 10
In the end the dolphin, a tertiary consumer, will only be able to produce 10 Kcal, when in the food web the producer had 10,000 Kcal.
The 10 percent rule is not entirely accurate, since the effective transfer can be less or more than 10 percent. However, in most cases, the average energy transfer is around 10%, which complies with the rule.

why it is so important for the body to be protected against viral pathogens?
Answer:
Certain viral pathogens can lead to death. Viruses like Human Immunodeficiency Viruses (HIV) are not considered lethal on their own but lower your body's ability to fight infections, and over time cause Acquired Immunodeficiency Syndrome (AIDS). If infected by this virus you could be killed by the common cold. That is why it is important to be protected against viral pathogens.

Which best describes how food availability affects the carrying capacity of an area?
A . as food availability increases, the carrying capacity increases in aquatic food webs only.
B. as food availability increases, carrying capacity increases in all ecosystem.
C. as food availability increases, the carrying capacity decreases in terrestrial food webs only.
D. as food availability increases, carrying capacity decreases in all ecosystem.
Answer:
I believe your answer would be "B"
Explanation:
If the food supply increases for a spider, they will reproduce faster, creating more food for the next animal in the food chain, and then that animal will reproduce faster, creating more food for the next animal, and so on! This would create more room for more animals because they can reproduce faster and create more all together.
Have a blessed day, please mark BRAINLIEST if correct! :D
The statement that best describes how food availability affects the carrying capacity of an area is as food availability increases, carrying capacity increases in all ecosystems. Thus, the correct option is B.
What is Carrying capacity?Carrying capacity may be defined as the maximum number of individuals that can live in an ecosystem without undergoing competition.
The increase in food availability gives the organisms the energy for survival and reproduction through which they can produce their offspring in the natural environment.
Almost all types of ecosystems favor food availability when it talks to increasing carrying capacity. Because the fact behind this concept remains the same for all ecosystems.
Therefore, the correct option for this question is B.

when the body removes carbon dioxide bu the way of respiratory system what happens to the ph of blood
the more carbon dioxide in the blood the more acidic it will be. so when it is removed the acidity will decrease.
so the pH increases
When the body removes carbon dioxide, the PH of blood increases
The body control the blood's acid-base balance through different ways. The organs used for this control is lung, kidney and buffer systems.
The lung can control blood pH through the release of carbon dioxide. Carbon dioxide acidic and its accumulation in the body leads to an increase in PH.
When the blood PH is too low (i.e. acidic), the body increases breathing so as to expel(remove) more carbon dioxide thereby increasing the PH of the blood.
