Answer: Cellular Respiration
Explanation: ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen.

describes the response of auditory nerve fibers that allows for the plausibility of the theory of frequency representation:
The cochlea sends information about sound stimuli to the cochlear nucleus of the brainstem via auditory nerve fibres.
Depending on whether receptor cell population in the cochlea is contacted, the neurons that give rise to these fibres can be split into two categories.
Basically, vibrations (sound signals) are transmitted to the brain via the auditory nerve. Remember that hearing sounds is made possible by several different parts of the ear, not just the auditory nerve. A number of additional ear components are also involved.
Some sensory systems that provide information that is relevant to motor functions are distinguished by a "spatial code" in addition to a "temporal code" because they display characteristics that are tailored to specific spatial directions. Examples include otolith and semicircular canal afferents, as well as muscle spindle afferents.

suppose a scientist discovers a gene that he believes promotes pluripotency. he could test this possibility by depleting it from the somatic nucleus to see if nuclear reprogramming becomes less efficient
What is Pluripotency?The capacity of some substances to elicit a variety of unique biological reactions is referred to as the pluripotency of biological molecules. As with pluripotent stem cells' ability to differentiate into several cell types, pluripotent is also used to denote something that has no predetermined developmental potential.
What makes anything pluripotent?A term with several "potentials" is plural. In other words, these cells have the capacity to transform into all more than 200 different cell types in the body. Both induced pluripotent stem (iPS) cells, which are reprogrammed from adult tissues, and embryonic stem cells are pluripotent.

The otter allele is found in Lane 2. To which population does it belong
DNA fingerprints are all the genetic markers used to differentiate individuals or populations. In the exposed example, the otter from lane two belong to population 2, Esther passage, because its band is 890 PB in length.
What is DNA fingerprint?
We can refer to DNA fingerprint as the group of genetic markers that differentiate an individual from another individual, or a population from another population.
Genetic markers are unique DNA fragments that are not identical in all individuals or populations. These fragments provide unique information about the individual or the population, so they are usually used to analyze differences, identify a progenitor, or solve a crime.
DNA prints are used to identify the population origin of an individual, or filial relationships, among others.
In the exposed example, we have DNA samples of 8 individuals belonging to three different populations.
Two alleles are used as markers to identify the individual belonging to each group.
Population 1 ⇒ Unakwik inlet ⇒ 610 and 890 bp band length ⇒ both allelesPopulation 2 ⇒ Esther passage ⇒ 890 bp band length ⇒ one allelePopulation 3 ⇒ Wells bay ⇒ 610 bp band length ⇒ the other alleleTo identify individuals belonging to each group, we just need to count the number of band they express.
In the case of individual number 2 (lane 2), there is only one band. So we can dismiss population 1 (because this population has the two alleles).
The expressed band is approximately 890 pb length. It means that it belongs to population 2, Esther passage.

a branch of the autonomic nervous system that prepares the body for activity by speeding up the heart rate is called the system.
The sympathetic branch of the autonomic nervous system raises heart rate, blood pressure, and breathing to get the body ready for exercise. The sympathetic division also encourages the liver to release glucose for use as fuel.
To increase heart rate, the sympathetic nervous system (SNS) produces the catecholamines epinephrine and norepinephrine. The primary function of the parasympathetic nervous system is to calm down or lessen your body's activity. The rhyming expressions "rest and digest" or "feed and breed" are good methods to remember what your parasympathetic nervous system performs because of the messages they carry. When a person is confronted with a dangerous or terrifying scenario, one component of the autonomic nervous system, known as the sympathetic nervous system, reacts. It will automatically raise heart rate and respiration while moving blood to the muscles.

Answer:
Reproduction.
Explanation:
One piece of evidence that a virus is non-living is that it cannot reproduce on its own.
Unlike living organisms, viruses require a host cell to replicate and produce more viruses.
This dependence on a host cell for reproduction suggests that viruses are not truly alive, as they lack one of the key characteristics of living things, which is the ability to independently sustain and replicate themselves.

which of the following will occur after ovulation? group of answer choices the corpus luteum prepares to become a corpus albicans. the corpus luteum secretes estrogen only. the endometrium enters its secretory phase. the secretion of anterior pituitary gonadotropins is enhanced.
The interaction of hypothalamic and anterior pituitary hormones with reproductive tissues and organ hormones regulates the human male and female reproductive cycles. In both sexes, the hypothalamus regulates and causes pituitary hormone release.
The normal menstrual cycle is a sequential event in which the hypothalamus secretes GnRH, the pituitary gland secretes follicle stimulating hormone and luteinizing hormone (LH), and the ovary responds to those hormones by recruiting a dominant follicle and secreting estradiol and inhibin A. Estradiol stimulates cervix endometrial proliferation and mucus production. A peak in estradiol causes the release of LH, which is responsible for ovulation and the subsequent secretion of progesterone by the corpus luteum, which involutionates 14 days later if not stimulated by hCG (pregnancy). Normal menstrual cycles last 28 days, with a two-day fluctuation in the same woman considered a normal pattern or a regular cycle. The normalcy of these events would allow for successful embryo implantation in the case of trying to conceive. To be fertilized, a capable spermatozoon must reach an adequate ovule during the ovulatory stage. The spermatozoon can survive for up to 5 days in the feminine genital ractum , but the ovum can only be fertilized for 12-24 hours. Fecundation takes place in the distal third of the fallopian tube, and the fecundated zygote develops into a morula before being implanted at the endometrium four days later.

There are 44 autosomes and two sex chromosomes in each person. Human somatic cells have 22 pairs of autosomes and either two X chromosomes or an X and a Y chromosome.
A chromosome is a long molecule of DNA that contains the genetic material of various organisms. Most eukaryotic chromosomes exist in tandem with histone proteins, which aid in DNA stability.
Each chromosomal pair is made up of one chromosome from the mother and one chromosome inherited from the father. Human males produce gametes with two types of sex chromosomes, X and Y, whereas human females produce gametes with only one type of sex chromosome, X.
The male gamete is referred to as heterogametic or heteromorphic, while the female gamete is referred to as homogametic or homomorphic, depending on the gamete produced. The number of chromosomes varies from organism to organism, but they are an important part of the cell because they not only impart essential qualities to the organism and also aid in the synthesis of important proteins which play important metabolic roles, resulting in the organism's proper functioning.

The founder effect is an example of _______.
Answer:
The founder effect is an example of genetic drift
explanation:A population has members with the same appearance and features, such members encounter similar problems in the environment they live in. Some members of the population start living in a different place due to some reason. In that new area, they form a colony and start to adapt to different environments. This is called the founder effect. This brings change into sets of genes causing genetic drift.
Which of these shows an example of an insertion mutation?
The figure 3 shows an example of an insertion mutation.
What do you mean by insertion mutation?
An insertion is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping.
Moreover, an insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly.
An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand "slips," or wrinkles, which allows the extra nucleotide to be incorporated.
