How does size influence the appearance of a star? Give an example in your response.
Answer:
when the size of a star increases, luminosity of star also increases.
The color of a star is decided by the surface temperature of the star and the temperature of a star depends on the size of star.
The smaller stars have low temperature and they are usually red (Proxima Centauri - red dwarf star).
The massive stars have higher temperature and they are usually blue (for exaple Zeta Puppis - Blue supergiant star).

B. Hormones provide feedback that affects neural processing.
C. Sensory receptors in bones send signals about body position to the brain.
D. The brain sends signals that control the speed at which food moves through the intestines.
Answer:
he endocrine system secretes hormones into blood and other body fluids. These chemicals are important for metabolism, growth, water and mineral balance, and the response to stress. Hormones provide feedback to the brain to affect neural processing. Reproductive hormones affect the development of the nervous system.

Which is correctly matched with the
appropriate number of chromosomes
in each daughter cell?
A Meiosis: 2 sets of 23 chromosomes
B. Meiosis: 1 set of 23 chromosomes
C. Mitosis: 1 set of 23 chromosomes
D. Mitosis: 2 sets of 46 chromosomes
The match for the appropriate number of chromosomes in each daughter cell is "Mitosis: 2 sets of 46 chromosomes". Option D. This is further explained below.
What is Mitosis?Generally, Mitosis is simply a kind of cell division that produces two daughter cells with the same number and type of chromosomes as the parent nucleus, as seen in normal tissue growth.
In conclusion, "Mitosis: 2 sets of 46 chromosomes" matches the appropriate number of chromosomes in each daughter cell.

Which of the following is not a stage in hurricane formation?
A)
Thunderstorms in a low-pressure area combined with the Earth’s rotation cause the storm’s initial rotation.
B)
Pollution in the atmosphere raises the temperature of the air, creating a depression.
C)
Warm, moist air rises from the sea and increases the storm’s energy.
D)
As water from the sea turns into water vapor, latent heat enters the storm, causing the storm’s energy to increase.
E)
As condensation (rain) occurs, latent heat is released, which warms the air and makes it lighter, causing the hurricane to increase in strength and intensity.
Answer:
B
Explanation:
Because if that was the case we would have hurricanes everyday
why does the sodium potassium pump require ATP?
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

explain why land is considered a resource?

A biologist reads an article in a scientific journal that describes how the legs
of different organisms look and function differently, but appear to be
constructed from the same basic bones. He compares a drawing of the
skeletal structure of a porpoise's fin with one of an elephant's leg. (7A)
What aspect of the theory of evolution do these drawings support?
Answer:
Homology
Explanation:
The aspect of the theory of evolution that the drawings support is homology. Homologous organs are organs of different organisms that look similar in structure but perform different functions in reality.
Organs that are built on the same or similar basic plans in the same organisms but perform different functions are thought to have been from the same ancestor. Hence, homology or homologous organ represents one of the evidence used to support the theory of evolution which opines that all living organisms descended with modifications from common ancestors.

Why might it be hard to restore a wildlife population using custodial management?
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.
What is the process of evolution?Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations. According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.These characteristics are easily trasffered from one generation to other generation.
Therefore, The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.

Where do electrons go after they leave chlorophyll?
Answer:
They leave and find somewhere else to replace the previous electron that had left just like it did and repeats the same process over and over again.
Explanation:
This is what i found on the internet to further explain my response, "The electron lost from the chlorophyll a special pair is replenished by splitting water. The passing of the electron in the first part of the electron transport chain causes protons to be pumped from the stroma to the thylakoid lumen." "When light strikes chlorophyll (or an accessory pigment) within the chloroplast, it energizes electrons within that molecule. ... The excited electrons leave chlorophyll to participate in further reactions, leaving the chlorophyll “at a loss”; eventually they must be replaced."
