Explanation:
If after studying a population for a trait determined by a single pair of alleles you fi nd that the population is not in equilibrium, what possible reasons might explain the lack of equilibrium
Answer and Explanation:
The criteria for maintaining a Hardy-Weinberg equilibrium are:
Random matings: mating probabilities between individuals with determined genotypes depends on the products of frequencies of those genotypes. No superposed generations: each individual can leave their gametes in the pool only once. No mutations: There is no incorporation into the genetic pool of new gametes originated by mutation of preexistent alleles. No migration: There is no incorporation of gametes originated in another population. Infinite population size: the probabilities of randomly taking an A gamete from the pool are p and the probabilities of taking a B gamete from the pool are q. No natural selection: Each individual has the same surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.If one of these points does not carry out, then the population under study is not in equilibrium.
If endogamy or exogamy occurs affecting random mating, If genetic drift is going on, the population is not infinite-sized and there are no random matings,If there exist genetic flux, which means that the population is not closed and migration occurs, If natural selection is acting over the population, If there occur mutations,Then the observed allelic and genotypic frequencies are different from the expected ones if the population under study was in H-W equilibrium.
Thomas A. Edison, famous for his invention of the light bulb, once said “I have not failed. I’ve just found 10,000 ways that won’t work.” What does this mean to you? Why is this a good way to describe science
Answer:
Because he has tried many other forms and become a master on the subject therefore from a business standpoint he could corner the production. But from a moral standpoint he has overcome a great challenge that will influence generations to come. It is a good way to describe science because it shows that to overcome a great challenge requires great patientice and time and trial and error.

What would Iraq have to do in order to reach a zero growth rate? What kinds of challenges might the Iraqi government face in trying to implement these measures?
Answer:
Iraq will have to massively reduce the birth rate to achieve a zero growth rate. In the middle east, there is more sexual freedom which may cause sexual education to be useless. Iraqi government would most likely have to give widespread contraception to its citizens.They would either have to lower birth rates or increase death rates. It would be more practical for the Iraqi government to provide contraception's and sexual education among its citizens to decrease birth rates.

HELP ME ASAP HELP ME PLZZZ HELP MEEEEEEEEE
Answer:
Precise, but not accurate
Explanation:
First, let's define precision and accuracy.
Precision: how close multiple measurements are
Accuracy: how close the measurements are to the true measurement
The three measurements are:
167.0 g, 166.9 g, 167.2 g
The true mass is 172 grams.
We can see that each measurement is far from the actual value of 172 grams: about 5 grams off. They are not close to the actual measurement, so they are not accurate.
The three measurements are very close to each other. They are all within 0.3 grams of each other. The measurements are all close to each other, therefore they are precise.
Therefore, the measurements are precise, but not accurate.
Answer:
More precise than accurate.
Explanation:
Precision is a measurement of how close your measurements to each other, accuracy is a measurement of how close your measurements are to the true value.
This type of biomolecule is responsible for numerous cellular functions including increasing reactions, providing structure for healing, antibodies to fight infection and aiding in transport of substances and sending signals to cells. What is the name of this biomolecule?
Answer:
Proteins
Explanation:
Biomolecules are any organic molecule, meaning they contain carbon and they are produced by cells in living organisms, and they generally aid in the functioning of that living cell. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
Proteins are large biomolecules, as they are also macromolecules.
Proteins are responsible for cellular functions and regulation of the body's tissues and organs.
When we talk about providing structure for healing, then proteins fit perfectly as collagen works on quick healing while immunoglobulin is an example of a protein that fights of harmful organisms.
Ferritin, Hemoglobin is an example of a protein that transports essential molecules from one part of the body to a target organ or destination.
Insulin for example is a protein that sends signals to target organs and is considered very important.

4. hormones
Answer:
2. enzymes
Explanation:
enzymes are proteins made up of amino acids and acts as a biological catalyst in our body but however, glucose serves as the purpose of energy provider for metabolism which is not a proteinHow does a virus get into the cell?
Answer:
A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host—and the cells within the host—that can be infected by a particular virus.
Answer:
Viruses initially stick to cell membranes through interactions unrelated to fusion proteins. The virus surfs along the fluid surface of the cell and eventually the viral fusion proteins bind to receptor molecules on the cell membrane (4). If only binding occurred, the two membranes would remain distinct.

Look at the image above. How did endosymbiosis impact the structural differences between bacteria, animals, plants, and fungi? CLAIM: EVIDENCE: REASONING:
Answer:
What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.
Explanation:
Endosymbiosis is important because it is a theory that explains the origin of chloroplast and mitochondria. It is also a theory that explains how eukaryotic cells came to be. DNA, RNA, Ribosomes and Protein Synthesis
This provided the first substantial evidence for the endosymbiotic hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.
