How does gene pool and allele frequency terms relate to another??
Answer:
Allele frequency is how often an allele occurs in a gene pool
Explanation:
Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene. The gene pool of a population consists of all the copies of all the genes in that population.
In some cases tumors support their unrestricted proliferation producing a growth factor that they also respond to. this mechanism is called _____ signalling
The tumors support their general proliferation by producing a growth element that they also respond to, this mechanism is called autocrine signalling.
What is autocrine signaling?Autocrine signaling means the display and secretion of an extracellular intermediate by a cell followed by the binding of that mediator to receptors on the same cell to start signal transduction.
A form of autocrine signaling is the secretion of IL-1 by macrophages.
Thus, this mechanism is called autocrine signalling.

Large holes in the ground left over after mining operations are sometimes called what
Answer:
a pinge?
Explanation:
Large holes in the ground left over after the mining operations are sometimes known as the pinge. These are made up by the mining activities that are making the depression or the sink holes in it.
What kind of activity is pinge made up by ?It is the human activity in which the extractions are done in order to make the use of the resources . It is the artificial human activity.
This depression or sink-hole is usually caused out by collapse of the old underground mine works which are close to Earth's surface.Unlike any natural landforms , a Pinge is the direct result of the human activity. The collapses do make up big larger holes that almost makes the pinges in the process of mining.
Pinge is also formed by the surface in which the land is not supported properly and the extraction has made the holes in the lands because of the more pressure and the type of extracting machines that are being used in it.

How many spermatids result from one spermatogonium?.
Four (4) spermatids result from one spermatogonium. Details about spermatogenesis can be found below.
What is spermatogenesis?Spermatogenesis is the process by which sperm cells are produced from the testes of a male animal.
Spermatogenesis involves series of mitotic and meiotic divisions that finally result into the haploid sperm cells.
Spermatids are haploid cells produced by meiosis of a spermatocyte that develops into a spermatozoon.
The spermatogonium divides mitotically into primary spermatocyte which then develops into secondary spermatocyte via meiosis. Each secondary spermatocyte forms 4 spermatids.

If a person who commits a crime leaves even the smallest speck of their blood, hair, or other organic matter, the DNA in this material can be amplified by PCR subjected to genetic analysis.
What is the use of PCR in crime scenes?
With PCR, crime scene investigators can extrade strains of DNA into quantities that may be recognized and connected to a suspect. Biologists can produce a couple of copies of character genes to look at gene function, evolution, and different topics.
PCR is a procedure wherein tens of thousands and thousands of copies of a particular collection of DNA may be made in a count number of just a few hours. This is crucial for forensic DNA samples because the DNA regularly located at crime scenes is constrained in each amount and quality.

Which of the following are an advantage and disadvantage of hydrogen energy use?
A. Advantage: Hydrogen is easy to store.
Disadvantage: Hydrogen is scarce.
B. Advantage: Hydrogen is easy to transport.
Disadvantage: Hydrogen emits pollution.
C. Advantage: Hydrogen is an efficient form of energy.
Disadvantage: Hydrogen is expensive.
D. Advantage: Hydrogen fuel has established infrastructure.
Disadvantage: Hydrogen is scarce.
Hydrogen is used as an energy source as it is an efficient form of energy compared to the other sources, but it is expensive. Thus, option C is correct.
What is hydrogen energy?
Hydrogen energy is the use of hydrogen gas in the production of energy that is more efficient than the other sources as it has a greater fuel conversion rate than petrol and diesel.
Ther hydrogen energy is also a disadvantage as it is expensive as it includes steam reforming and electrolysis which are costly processes and hence are not used globally.
Therefore, hydrogen energy is efficient but is an expensive method.

The class of drugs for human immune deficiency virus infection which reduces how well HIV genetic material can be converted into human genetic material is called The Nucleoside Reverse Transcriptase inhibitors (NRTIs)
Meaning of HIV and NRTIsHIV also called human immunodeficiency virus is an infection that always attack the body immune system but majorly the white blood cells which is called the CD4 cells. The human immunodeficiency virus destroys these CD4 cells thereby causing a persons immune system to be weak and unable to fight other infections, leading to ill health.
The NRTIs also known as the Nucleoside Reverse Transcriptase inhibitors prevent viral replication, binding and interaction with the CD4+
