Why do plants need water, light, and carbon dioxide?
Answer;
these are used in photosynthesis altogether. light splits the water into hydrogen and oxygen. water is used to manufacture starch, soften the testa during germination, dissolve food as well. carbon dioxide is also used during photosynthesis.
All of the following affect the temperature at which magma forms except what?
Except viscosity, all the other factors affect the temperature at which magma forms. Therefore, the correct option is D.
What is viscosity?Viscosity can be defined as a measure of the fluid's resistance to flow. Magma can be defined as a very hot molten or semi-molten substance that is formed due to volcanic eruptions. They are responsible for the formation of the igneous rocks.
There are many factors that affect the temperature at which magma forms:
Pressure-increasing pressure can raise the melting temperature of rocks, while decreasing pressure can lower it.Composition of source material: The composition of the rocks in the mantle can vary depending on the location and geological history of the region. Presence of water: Water can lower the melting point of rocks, which can lead to the formation of magma.But viscosity does not play any role in impacting the temperature at which magma forms. Therefore, the correct option is D.

Describe the role of gravity in maintaining the atmospheric layer around Earth. I will mark as brainliest
Answer:
Hi so the answer is that Gravity pulls the gas molecules towards Earth's center. The pull of gravity is stronger closer to the center at sea level. Air is denser at sea level where the gravitational pull is greater. Gases at sea level are also compressed by the weight of the atmosphere above them.

Answer:
Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.
Charles Darwin and Alfred Russel Wallace figured out that ____ influences the course of random evolution?
A. Dog breeders
B. Natural selection
Answer:
B. Natural selection
Explanation:
Explaination:
Answer:
B. natural selection
Explanation:
Natural Selection: Charles Darwin & Alfred Russel Wallace. A visit to the Galapagos Islands in 1835 helped Darwin formulate his ideas on natural selection. He found several species of finch adapted to different environmental niches. The finches also differed in beak shape, food source, and how food was captured.
A scientist is comparing the sequences of related genes among three species. Two of the species have very similar sequences, while the sequence of the third species differs greatly from the others. T
Hi. The question you presented above is incomplete. This makes it impossible for this question to be answered. However, when searching for your question on the internet, I was able to find another question exactly like yours, which asked you to explain the evolutionary relationship between these three species. If that's the case for you, I hope the answer below will help you.
In a simplified way, we can infer that among the three species presented above, the third presented a faster evolution than the first two and this is what explains the difference between the gene sequences between the species. As the question presents, the three species have related genes, which indicates that they had a common ancestor, however the difference in the gene sequence of the third species shows that it evolved first, showing changes that cannot be noticed in the first two species that are evolving more slowly.
What is the evidence of variation when individuals in a population or group differ in some trait of interest
Answer:
When the more dominat trait starts to show up in most of the population while keeping the specis the same. This can be very benifitial to the population or harmful depending on the trait that is getting passed down.

What are chromosomes?
Answer:Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.
The word "chromosome" is derived from the Greek terms "chroma" and "body" (soma).

What ideas were changing in the scientific community at the time of Darwin's travels? How might those new ideas influenced Darwin?
Answer and Explanation:
At the time of Darwin's travels, the scientific community was beginning to abandon ideas linked to creationism to adopt more scientific and testable concepts, less linked to religiosity. Darwin was very influenced by these new concepts and decided to study a way to apply them to the biological diversity that planet earth presented. He wanted to explain this diversity through scientific data, obtained by experiments and logical reasoning, without the interference of creationist concepts and that would show how life on earth changes over the years and how species of living beings were created. This was one of the kicks that made him start his travels and his studies on biological evolution.

A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere
Answer:
The correct answer is (B).
Explanation:
Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...
Increased carbon in the atmosphere
This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.
The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
What is Deforestation?Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.
When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.
This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.
But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.
Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of an axon, and he has noted that every time a segment fires, the _____ flood in from the outside of the cell, while the prior segment returns to its resting potential. Please choose the correct answer from the following choices, and then select the submit answer button.
Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.
