Explanation:
Causes the wavelength of light from a star to either compress or stretch l
Answer:
The reason is that the universe is expanding, it is compressed because the space is expanding, the waves are being stretched out.
Explanation:
wavelength, distance between comparing purposes of two sequential waves. "Comparing focuses" alludes to two focuses or particles in a similar stage i.e., focuses that have finished indistinguishable divisions of their occasional movement. As a rule, in cross over (waves with guides wavering at right points toward the course of their development), frequency is estimated from peak to peak or from box to box; in longitudinal (waves with focuses vibrating a similar way as their development), it is estimated from pressure to pressure or from rarefaction to rarefaction.
The "wavelength compression" has a probability to produce cultivating signal at the nano-meter frequency by crushing optical frequency of the noticeable laser bar on a high energy electron pillar.

Scientists use brown rats to study genetic diseases because brown rats and humans share many of the same genetic diseases. Which statement describes why brown rats experience similar genetic diseases as humans
The correct statements associated with question are given below:
Brown rat have an omnivorous diet similar to that of humans.
Brown rat have nucleotide sequences similar to those of humans.
Brown rat go through embryonic stages similar to those of humans.
Brown rat produce gametes through a process that is similar to that of humans.
Answer:
The correct answer is - Brown rat have nucleotide sequences similar to those of humans.
Explanation:
Genetic disease are the disease that are related to the mutation in the gene or DNA in the genome of an organism. DNA are made up of the nucleotde sequences which are specific for the specific function and any cahnge of the function due to the alteration or change in the sequence will result in the genetic disease and passed to the next generation.
Most of the genetic disease takes place due to mutation in nucleotide sequence so if two distinct organism share same nucleotide sequenc e the most likely to show similiar type of genetic disease.

The number of chromosomes found within the cells of any given species is a constant number maintained through multiple generations. The accumulation of chromosomes is prevented because the process of meiosis creates –
a
mutations that destroy extra DNA
b
genetically identical daughter cells
c
haploid gamete cells
d
offspring through asexual reproduction
Answer:
c haploid gamete cells
Explanation:
The vast majority of cells in the body are diploid, meaning they have two copies of every chromosome. However, like the question says, if during fertilization, the diploid cells fuse, then there will be 4x copies of every chromosome in the first generation, 8 in the second, and so on.
Meiosis creates haploid cells from diploid cells through one round of DNA replication and then two cell divisions to create haploid cells, one copy of each chromosome.
During fertilisation, when the gametes fuse, they make a diploid cell that develops into a new organism.

A normal zygote has 23 of what?
Answer: I believe it’s 23 chromosomes
Explanation:
During fertilization gametes from the sperm combine with the gametes from the egg ofc which forms a zygote. And the zygote will contain two sets of 23 chromosomes which will make the 46.
A normal zygote has 23 pairs of chromosomes, which are homologous.
Explanation:
Meiosis is the sexual reproduction method used, which has sex cells like sperm and eggs. This creates four daughter cells with half as many chromosomes.
With each of the gametes created by the process of meiosis, it will have one pair from each of the homologous chromosomes. When both of the gametes meet during the fertilization stage, the zygote will have 23 pairs of chromosomes.
While this is the normal amount a human has, things can happen that can mess up the cell division stage and add an extra chromosome.
Can someone please give me a full paragraph of what do Lucille’s cells need in order for her body to function properly? How might a problem with Lucille’s respiratory system or circulatory system make it difficult for Lucille to play soccer?
Please respond ASAP
Answer:
In order for her body to act correctly, Lucille's cells require glucose and oxygen.
A problem with Lucille's respiratory system leading to low levels of oxygen in her cells is known as Hypoxemia.
Having low levels of oxygen in her cells will make it difficult for Lucille to play soccer because she would not be able to breathe .If her respiratory system doesn't function properly, so enough oxygen molecules will not move into her respiratory system , ensuring that her cells won't have enough oxygen molecules. Playing soccer is difficult if you don't have enough air.
Explanation:
ABOUT HYPOXEMIA -: It is called hypoxemia to have low oxygen levels in your blood. It is called hypoxia to have insufficient oxygen levels in the tissues. Hypoxemia at high altitudes can occur. Hypoxemia that induces low levels of oxygen in the tissues of the body is called hypoxia. The two words are often used by people interchangeably, but they are not the same thing.
The capacity of the body to supply normal amounts of oxygen to the blood can interfere with a number of conditions and circumstances. Some of hypoxemia's most prevalent causes include:
Heart problems, heart defects included .
Lung disorders such as asthma , bronchitis, emphysema.
High-altitude areas where oxygen is lower in the air.
Powerful drugs for pain or other conditions that delay respiration .
Sleep apnea (breathing impairment during sleep) .
Lung tissue inflammation or scarring (as in pulmonary fibrosis).

When there is an excess of glucose, the body will store the extra glucose
by attaching it together to form glycogen. What type of reaction is this?"
Answer:
Anabolic reaction
Explanation:
The type of reaction involving the storage of extra glucose in the body as glycogen would be an anabolic reaction.
An anabolic reaction is a form of metabolism that involves the building up of molecules in the body of organisms. It is as opposed to catabolic reactions in which molecules are broken down in the body of organisms.
Most anabolic reactions require the consumption of energy while most catabolic reactions lead to the release of energy. Energy-consuming reactions are said to be endergonic while energy-releasing reactions are said to be exergonic.

Meiosis benefits a population by allowing for sexual reproduction. Unlike asexual reproduction, sexual reproduction actively increases the amount of –
a
genetic variations
b
available nutrients
c
dominant alleles
d
autosomal DNA
Answer:
a. genetic variations
Explanation:
Genetic variation is the amount of differences in the DNA there is between individuals in a population. Generally, a high level of variation means the population is fitter, as they can more likely adapt to any changes.
Meiosis produces haploid gametes that fuse during fertilisation. These gametes can have any combination of alleles present in the individual, can undergo crossing over, and can fuse with any of the gametes in the other partner. These all provide opportunities for genetic variation and creating new combinations of alleles.

I'm guessing here but, some advantages are, embryonic stem cells are very effective at repairing damaged tissues, but they are difficult to obtain, and either have to be obtained from umbillical chords of babies, or from fertilized embryos from a laboratory. So I am guessing they would be expensive/difficult to source because you would either have to collect umbillical chords from babies, or have to purchase eggs from women, and they are ethically questionable to use because you are essentially making potentially viable embryos and then killing them. Hope this helps.
Explanation:
group the terms according to the subatomic particle they describe.
Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed question can be seen in the document attached.
There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).
A. Found in all matter
Answer: They are both found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).
B. Negative charge
Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the electron
C. Exists in the nucleus
The subatomic particles found in the nucleus are the protons and neutrons.
D. Attract opposite charges
They both (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.
E. Moves at extreme speed
Of the two subatomic particles mentioned, electrons move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.
F. Bound by strong force
The protons are bound by strong nuclear force which binds them to the nucleus of the atom.

Which homeostatic process requires energy to move particles across the plasma membrane?
A. active transport
B. passive transport
C. dynamic equilibrium
D. osmosis
Active transport requires energy to move particles across the plasma membrane. Therefore, the correct option is A.
What is Active transport?A type of cellular transport known as active transport uses energy to push molecules or ions across their concentration gradient (from an area of low concentration to an area of high concentration) across the plasma membrane. It is powered by cellular energy, which is usually present in the form of ATP (adenosine triphosphate).
Because it enables the cell to move important molecules against their concentration gradient and maintains the constancy of the cell's internal environment, this mechanism is essential for preserving homeostasis in the cell. Active transport requires energy to move particles across the plasma membrane.
Therefore, the correct option is A.
