What is the variety of gene combinations that exist within a population called?
A population's genetic diversity can be quantified via genetic variation, genetic diversity is the term used to describe the genetic variation of an entire species.
What is genetic variation?Each variant of a gene is referred to as an allele, and genetic variations are the variances in DNA segments or genes across individuals.
A population's naturally occurring genetic diversity is studied by population geneticists. A population's gene pool is made up of all the genes and different alternative or allelic versions of those genes.
Some genes exist in a number of forms, all of which share the same genetic locus on a chromosome.
Therefore, genetic diversity is the variety of gene combinations that exist within a population.

8. im not sure abt this one, sry :(
9. yeah, true
10. c
Explanation:
Pro phase is the starting stage of the division where the cell division begins. Spindle fibers are broken into half and the type of division that is present in gametes is reduction division that is the meiosis. Synapsis occurs during mitosis.
What is synapsis ?It is defined as the stage in which the pairing of the homologous chromosomes take place.
Chromosomes do not line at the equator as the lining of the chromosomes at the equator occurs on the stage of mitosis where it is possible to see the V,J and L shapes of the paired chromosomes. After this stage the exchange of genetic material takes place.Chromatin do not change into chromosomes in the metaphase.
Mitosis is present only to make the duplicate copies of the cell. The identical daughter cells are made when the division of mitosis is taking place in the cell. Chromosomes are first visible in the prophase. A centromere holds two sister chromatids together.
In meiosis crossing over takes place in anaphase 1.

When an instruction for a variation of a trait is not shown in by the organism, but the organism carrys it and can pass it on to the next generations, these organisms are called _______.
a
dominant
b
carriers
c
recessive
d
holders
Answer:
b. carriers
Explanation:
Recessive alleles do not create a phenotype if a dominant allele is present BUT the organism itself is called a carrier because it carries the recessive trait.
Which student identified the correct step and the result of that process?
Frank claims step 1 is DNA replication which produces proteins needed by the organism to grow and develop
Emma claims step 2 is transcription, resulting in a double stranded RNA molecule needed for translation in the nucleus

Tyrone claims step 4 is the production of amino acids, which will form proteins, resulting in the expression of genes found in DNA

Can you write an essay about what makes a good rapper.
I will mark you Brainly.
Answer:
There are many rappers out there in the world yet only a few of them are really well known and recognized. Of course this is because they meet peoples expectations. Different people have different opinions on what makes a good rapper. Things that I think make a good rapper is that they need to have good flow, meaningful lyrics that actually make sense and not just rhyme any word with another that doesn't make sense. Another thing is how they are like as a person as well. If they are a pretty decent human being and meets peoples expectations then they will be considered as a good rapper. If the person is not only ignorant but also can't rap well then they are considered bad. Like I said many people have different opinions but these are just mines.

Answer:
The energy that goes into the trumpet to create the sound is a standing wave. (I think...)
Explanation:
When a person is blowing into a trumpet, a standing wave is being created based on the shape of the instrument. The trumpet is formed to produce sound. Notes sound different from one another because they represent different frequencies and therefore a different numbers of nodes.

List at least two variables that might influence the rate of cellular respiration.
Answer:
Answer below !
Explanation:
1) Oxygen Concentration
2) Temperature
3) Glucose Availability
Hope I helped and have a great day ∩^·ω·^∩ !
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.
What variable that influence the rate of cellular respiration?Since all living cells require both glucose and oxygen to operate properly, variations in the concentration of glucose have an effect on the rate of cellular respiration. If a cell's glucose level is low, it cannot produce energy in the form of ATP molecules.
High oxygen concentrations enable cells to perform aerobic respiration, which uses oxygen to build ATP and generates more ATP than anaerobic respiration, which occurs when oxygen is not present.
As a result, increased cellular respiration is often associated with warmer temperatures.
Therefore, Oxygen Concentration, Temperature, Glucose Availability

Energy Released from the cellular respiration of glucose is
A.First stores within ATP
B.Stored in the liver as fat
C.Turned into fat
D.used directly for body activity
Answer:
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule. To this extent, the Answer is (A)
Explanation:
Brainliest Please
Energy that is released from the cellular respiration is called as the ATP that is adenosine triphosphate. It is the energy currency of the cell.
What is the number of phosphate in ATP ?The number of phosphates in the molecule of ATP is 3 phosphates.
Glucose and the other food's molecules get broken down by the controlled stepwise oxidation in order to just provide the chemical energy in form of ATP and the NADH. Energy that is released during breakdown of the glucose and the other organic fuel molecules that are from the carbohydrates with fats and the proteins in the glycolysis is just captured and then stored in the ATP.
During the cellular respiration the glucose is just broken down in presence of the oxygen in order to just produce the carbon dioxide with water. Energy that is just released during reaction is just captured by energy-carrying molecule that is ATP (adenosine triphosphate).

Explanation: I took the test and got this one correct.
The items that are inferential statistics among the options would be:
Give the likelihood of data occurring by chanceTell you whether to call your mother about your resultsGive a measure of statistical significanceThis is largely due to the fact that inferential statistics refer to the branch of statistics that draws conclusions from a set of data. It is as opposed to descriptive statistics which focus on summarizing, describing, arranging, and or categorizing data in such a way that trends are shown at a glance.
Statistical parameters such as mean, mode, and median only measures attributes of data relating to the measure of central tendencies. Data summary is purely descriptiveHence, the items selected are those that are conclusive and not descriptive.
