CO₂ is a gas that composes the atmosphere, but its increase contributes to the greenhouse effect. C)CO₂ has increased as a result of increased human activities.
What is CO₂, and how does it affect the greenhouse effect?Carbon dioxide (CO₂) is a gas that, among other gases, composes the atmosphere, mainly the troposphere, which is closest to the Earth.
The balance of this gas in nature is very complex and involves interactions between the atmosphere, the plants, and the oceans.
CO₂ is essential for plants to photosynthesize. Photosynthesis transforms CO₂ into organic compounds and releases oxygen as final products together with carbohydrates.
This gas is not nocive at concentrations between 300 and 500 ppm. However, the current increase in CO₂ is a responsible component of the greenhouse effect involved in global warming and climate change. The rise in CO₂ is possibly the best documented.
The atmospheric increase of CO₂ follows a natural fluctuation trend that has been happening throughout the whole of Earth's history.
It has been proven that the current rise in CO₂ concentration overlaps the expected variation and that the reached levels at the moment exceed the highest past registered levels. This substantial increase must be related to human activities, such as forest destruction, industry, and fossil fuel uses, among many others.
The correct option is C. Carbon dioxide has increased as a result of increased human activities.

The process of _________________ produces the gametes - sperm and egg.
Answer:
meiosis
Explanation:
Answer: Meiosis
Explanation:
Why is meiosis important to sexually reproducing organisms?
Answer:
Meiosis is important for organisms that reproduce sexually because it is the cell division that serves to obtain gametes or sex cells.
Explanation:
Meiosis is a reductive cell division, involved in the gametogenesis process, where from a diploid cell haploid cells called gametes are obtained.
The gametes, also called sex cells, are responsible for containing the genetic information that each individual will transfer to their offspring.
In sexual reproduction, the importance of gametes is that the paternal and maternal gametes unite in a process called fertilization, to give rise to a diploid cell called a zygote.

Continue building the strand of mRNA until you have used all of the RNA nucleotides. What is the nucleotide sequence of the mRNA strand you built?
Answer:
This question is incomplete
Explanation:
However, mRNA can be built from a DNA sequence; i.e a DNA strand is used as a template for the production of an mRNA sequence. This process occurs during transcription. While the four nitrogenous bases in a DNA molecule are adenine, thymine, guanine and cytosine, in RNA the thymine is absent and replaced with uracil. While producing the mRNA strand, Uracil will be complementary to adenine, adenine will be complementary to thymine, guanine will be complementary to cytosine and cytosine will be complementary to guanine. This can be seen in the illustration below:
DNA sequence: T--G--G--C--A--G--C--T--A--C--C--G
mRNA sequence: A--C--C--G--U--C--G--A--U--G--G--C
Thus, while building a mRNA nucleotide sequence, the procedure above can be followed

Which of the following statements is true?
The dissolving power of water is very important for the transport of nutrients in blood.
The solid form of water is more dense than the liquid form, which is why ice floats.
Cohesion helps plants transport water from their roots to their leaves.
Surface tension is a measure of how much water molecules are attracted to other materials.
Answer:
The dissolving power of water is very important for the transport of nutrients in blood.
Explanation:
Water is known as the "universal solvent" because it can dissolve more substances than any other liquid. The dissolving power of water means that it can effectively transport nutrients, chemicals, and minerals. Plants rely on water to carry dissolved nutrients from the soil. Animals also benefit from water as a solvent.

What would most likely happen to a person who is not getting enough essential amino acids in his or her diet?
A.The body would synthesize the amino acids.
B.Muscle growth and repair would be limited.
C.Stored protein would break down.
D.The formation of proteins would increase.
Answer:
The correct answer I believe would be C
Explanation:
B. There would be reduced muscle growth and healing. The body cannot synthesise essential amino acids on its own; therefore, they must be consumed through diet.
What is the reason for body not using protein ?The body cannot use the protein it consumes for muscle growth and repair when a person's diet is deficient in critical amino acids. In addition to increasing the risk of injury, this can result in a loss of muscle mass and strength.
Additionally, in an effort to obtain the critical amino acids it requires, the body can start to break down protein that has been stored, which would result in a further loss of muscle mass and strength.
Alternatively, the body can create non-essential amino acids, thus whenProtein synthesis won't necessarily increase if a person isn't obtaining enough necessary amino acids. The body will instead concentrate on converting protein that has been stored into the vital amino acids it requires.
Therefore, a reduction in muscle growth and repair is the most likely consequence of consuming insufficient amounts of necessary amino acids.

When a plant cell, such as one from a peony stem, is submerged in a very hypotonic solution, what is likely to occur? A. The cell will burst. B. Plasmolysis will shrink the interior. C. The cell will become flaccid. D. The cell membrane will lyse. E. The cell will become turgid.
Answer:
The answer is "Option E".
Explanation:
The turgid relates to cells or tissues swelling from its transport of moisture. Some types of cells would become turgid because of moisture absorption in several distinct species. Its vacuole is swelling or pressure created mostly on cell walls, that's why whenever a cell membrane is submerged inside an extremely isotonic solution including a cell of a peony stem, the cell becomes turgid.
An hypotonic solution is a solution when compared to others have a relatively low solute concentration.
So when a cell is placed in a hypotonic solution, the cell will become turgid. (option E).
When this cell is placed in a hypotonic solution, there is the flow of water across the solution and its surrounding environment. In a hypotonic solution, the solute concentration is lower than inside the cell. This flow continues until there is a net flow and equilibrium is achieved. The cell in this process gains volume and becomes entirely turgid swelling up.Learn more about turgidity: https://brainly.com/question/18740086
