Answer:
The answer to this question is Transport would increase.
Explanation:
The transport would just increase.
In the given area-to-volume ratio, the transport would increase across the cell membrane. The correct option is B.
What is area-to-volume ratio?The surface area to volume ratio is merely the surface area divided by the volume of an entity. It calculates the surface area per unit volume of the object.
The crucial fact is that as the cell size increases, the surface to volume ratio decreases.
If the cell expands beyond a certain size, not really enough material can cross the membrane quickly enough to cater the increased cellular volume.
The surface area divided by the volume is the ratio. This suggests how much surface area is accessible in relation to the size of the cell.
The cell is very large if the surface area to volume ratio is small. If the ratio is large, the surface area exceeds the volume the cell will be small.
Thus, the correct option is B.

Explanation:
1) Reflection is when a ray hits something reflective then bounces back. For example, light reflects off a mirror, which is why you can see yourself in a mirror.
2) Wavelength measures the size of a wave. It is measured from the crest or trough of one wave to the crest or trough of another.
3) Refraction occurs when waves go through different mediums at different speeds. This is why a straw looks bent when in water.
4) Frequency is a way of measuring the speed of a wave. It shows how many waves pass every unit of time.
5) Absorption means that all of the waves were absorbed into the medium and none of them passed through.
Why do the temperatures change over the months?
O A. Because the Moon is tilted on its axis, it reflects more sunlight on Earth during different times of Earth's yearly orbit.
B. Because the Sun is tilted on its axis, parts of Earth get more sunlight during different times of Earth's yearly orbit.
O C. Because Earth is tilted on its axis, the stars reflect more light during different times of the Earth's yearly orbit.
D. Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit.
Answer:
Answer
Explanation:
B because the more the sun is titled the more heat=different season.
Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit. As Earth orbits around the Sun, its axis is tilted at an angle of about 23.5 degrees. Hence the correct option is D.
Why do the temperatures change over the months?The temperatures change over the months primarily because of Earth's axial tilt. As the Earth rotates around the sun, the angle at which sunlight hits different parts of the Earth changes.
This is because the Earth's axis is tilted about 23.5 degrees relative to its orbit around the sun. When a particular hemisphere is tilted toward the sun, it receives more direct sunlight, resulting in warmer temperatures.
Conversely, when that hemisphere is tilted away from the sun, it receives less direct sunlight, resulting in cooler temperatures. This cycle repeats itself annually, causing changes in temperatures over the months.
Hence the correct option is D.

How is the ocean affected by the releasing of excess carbon?
Answer:
Explanation:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

Professor Marcus has identified a new species of beetle in the Amazon Rainforest. The professor then investigates the process of gene expression in the cells of the beetle. Which is an expected result of the investigation?
A The processes of transcription and translation are unique in the beetle.
B The process of translation in the beetle is similar to other organisms, but involves a unique genetic code.
C The process of transcription in the beetle is similar to other organisms, but involves a unique set of nucleic acids in mRNA.
D The processes of transcription and translation, including the genetic code, are the same in the beetle as in nearly all other organisms.
Answer:
D The processes of transcription and translation, including the genetic code, are the same in the beetle as in nearly all other organisms.
Explanation:
Transcription is the cellular process where a specific DNA fragment called 'gene' is used as a template to create a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is then used to synthesize a polypeptide chain (i.e., a protein) in the ribosomes. In eukaryotic organisms such as, in this case, beetles, both transcription and translation are essentially the same processes, and the genetic code used in the protein synthesis is also the same. The difference between beetles is the variation among DNA nucleotide sequences (genomes) which are used as templates to synthesize mRNAs, thereby their final products (proteins) are also different.

What is the final result of genetic drift in populations of
Answer: Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100% frequency, of other alleles.Once it begins, genetic drift will continue until the involved allele is either lost by a population or is the only allele present at a particular gene locus within a population. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.
Explanation:
Answer:
decrease the genetic diversity of a population.
Explanation:
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time.
Genetic drift can cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.

Some evidence on the safety of vaccines.
Answer:
The safety and effectiveness of vaccines are under constant study. Because vaccines are designed to be given routinely during well-child care visits, they must be extraordinarily safe. Safety testing begins as soon as a new vaccine is contemplated, continues until it is licensed, and is monitored indefinitely after licensure.
Explanation:
Answer:
well
Explanation:
Before a vaccine is ever recommended for use, it’s tested in labs. This process can take several years. FDA uses the information from these tests to decide whether to test the vaccine with people.
During a clinical trial, a vaccine is tested on people who volunteer to get vaccinated. Clinical trials usually start with 20 to 100 volunteers, but eventually include thousands of volunteers. These tests can take several years and answer important questions like:

What is anaerobic respiration ?Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.
In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is an excellent electron acceptor. Anaerobes instead use less-oxidizing substances such as nitrate (NO−3), fumarate (C4H 2O2−4), sulfate (SO2−4), or elemental sulfur (S). These terminal electron acceptors have smaller reduction potentials than O2. Less energy per oxidized molecule is released. Therefore, anaerobic respiration is less efficient than aerobic.
