As a cell becomes larger, its volume stays the same in relation to its surface area. So the correct option is A.
What is cell division?There are two types of cell division. These are mitosis and meiosis. Most of the time when people talk about cell division, they are referring to mitosis. This is the process of the formation of new body cells. Meiosis is another kind of cell division that results in the formation of egg and sperm cells.
Mitosis is the fundamental process of life. During the process of mitosis, a cell duplicates itself along with all of its contents. This includes the chromosomes of the cells. Then the cell splits to form two identical daughter cells.
All the steps of mitosis are carefully controlled by certain genes because of the critical nature of this process. When mitosis is not being regulated correctly, various health problems such as cancer can arise.
Meiosis is the next type of cell division. This ensures that humans have the same number of chromosomes in each generation. Meiosis is a two-step process that reduces the chromosome number by half, from 46 to 23, to form sperm and egg cells. This is also called the reduction division.
Therefore the correct option is A.

What is Specialization?In order to become more effective, specialization in business entails concentrating on a single product or a small range of products. Specialization can boost productivity and give a company or economy a competitive advantage.
Macroeconomic specialization deals with the general advantage an economy holds in production, while microeconomic specialization deals with the specific actors and economic elements.
Specialization is an agreement within a community, organization, or larger group in which each of the members best suited for a specific activity assumes responsibility for its successful execution.

Where do green plants get there food?
Answer:
Green plants get their food from organic components.
Green plants make their own food by the process of photosynthesis. In this process the chlorophyll present in the leaves trap sunlight.
Explain how the following organelles ensure that a cell has the proteins it needs: nucleus, rough ER, vesicles, and Golgi apparatus.
Answer: The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
The explanation of how these organelles ensure that a cell has the proteins it needs below
The nucleus contains the genetic material of the cell: made up of one or more DNA molecules.
It governs all cellular functions and is also the place where ribosomes are produced, which have the important function of synthesizing or translating information for the production of proteins.
The rough endoplasmic reticulum is characterized by being formed by a series of channels, flattened sacs and cisterns, in these flattened sacs chains made of various peptides are introduced, with which complex proteins will be formed.
This structure's main function is to synthesize proteins, which are destined to different parts of the cell to develop multiple functions, in addition to controlling their structural and functional quality.
These same proteins travel to other parts of the cell, such as the Golgi apparatus.
Golgi apparatus is known as a cellular organelle whose function is to handle synthesized proteins.
The multitude of small vesicles are associated with the Golgi dictyosomes, grouped on the side adjacent to the ER and along the dilated rings of each cistern.
These Golgi vesicles are protein and lipid transport vesicles to and from the Golgi and between the Golgi cisterns.
Proteins, as they pass through the Golgi apparatus, undergo a modification process before being released.

The moon is bigger than the sun.
The sun changes size throughout Earth's orbit.
They are the same size.
Answer:
The sun is 400x wider than the moon, but the moon is also 400x closer to the Earth
Explanation:
Although the the sun is roughly 400x wider than the moon, the moon is aproximately 400x closer to the Earth, and that is why seen from earth, sun and the moon appear to be the same size.
So answer is the sun is 400x wider than the moon, but the moon is also 400x closer to the Earth.

Some scientists have been concluded that the legs of modern land vertebrates evolved from the fins of ancient fish. What most likely provided the evidence for this conclusion?
- study the fossils of ancient land vertebrates
- Identity the numbers of ancient fish and ancient land vertebrates
- comparing the number of genes in modern fish to the number of genes in modern land vertebrates
- comparing the movements of genes in modern fish fins to the limbs of modern land vertebrates
Answer:
1- study the fossils of ancient land vertebrates
Explanation:
Some scientists concluded after performing a number of experiments that the legs of modern land vertebrates evolved from the fins of ancient fish. With the passage of time evolution occurs within the body of organisms. These changes occurs due to the surrounding environmental condition of that organism. When the organisms live in water, fins were present but when they go to the land so these fins change into legs. This type of evidence is provided by the scientist after studying the remains of ancient land vertebrates.

Which hypothesis most likely explains the results at 60°C and 70°C? O A. The substrate has been used up because of the high temperature, O B. The enzyme has changed shape because of the high temperature. O C. The enzyme is only effective at very high temperatures, O D. The bonds in the substrate are weakened at high temperatures
Answer: Option B
The enzyme has changed shape because of high temperature.
Explanation:
Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.
High temperature changes the shape of enzymes.
Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.

How doe water change the shape of earth surface?
Answer:
water is constantly moving across the earth. The water is strong enough to break down soil in tiny pieces. What’s happening is a process called erosion. Erosion is: the process of eroding or being eroded by wind, water, or other natural agents.
"the problem of soil erosion".
Water also carries sand and moves it around, this obviously changes the shape of the earths surface!
