Explanation:
This is the answer that worked for me.
The process of change in a population over time and the process by which organisms that are better adapted to the environment survive and reproduce is called "evolution."
What role does evolution play in the life of an animal?Natural selection, the best-known mechanism of evolution, explains the gradual change in the genetic makeup of a population caused by mechanisms such as genetic drift, mutation, and gene flow. The survival and reproduction of individuals with advantageous traits, allowing those traits to become more common in the population over time through the evolution process and adding value to the animal's life.
Hence, the process of change in a population over time and the process by which organisms that are better adapted to the environment survive and reproduce is called "evolution."

An Earth scientist is testing how various soil mixtures affect plant growth. She begins with 10 soil types. For each mixture, she combines equal amounts of 2 soil types. How many soil mixtures must the scientist create in order to test all possible combinations of the 10 soil types?a. 20b. 45c. 55d. 90
Answer:
b
Explanation:
The correct answer would be 45.
Assuming that the 10 soils are each represented by A, B, C, D, E, F, G, H, I, J.
A can combine with 9 others as: AB AC AD AE A F AG AH AI AJ
B can combine as: BC BD BE BF BG BH BI BJ
C as: CD CE CF CG CH CI CJ
D as: DE DF DG DH DI DJ
E as: EF EG EH EI EJ
F as: FG FH FI FJ
G as: GH GI GJ
H as: HI HJ
I as: IJ
Adding all the combinations together = 45
In other words;
[tex]^{10}C_2[/tex] = [tex]\frac{10!}{(2!(10 - 2)!)}[/tex] = 45
The soil mixtures must the scientist create in order to test all possible combinations of the 10 soil types- b. 45.
Given
soil samples = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
each mixture must have two sample
SolutionWe have to mix 2 soils in equal amounts. Then, the total number of possible soil mixtures are:-1 and 2, 1 and 3, 1 and 4, 1 and 5, 1 and 6, 1 and 7, 1 and 8, 1 and 9, 1 and 10 = >92 and 3, 2 and 4, 2 and 5, 2 and 6, 2 and 7, 2 and 8, 2 and 9, 2 and 10 => 83 and 4, 3 and 5, 3 and 6, 3 and 7, 3 and 8, 3 and 9, 3 and 10 => 74 and 5, 4 and 6, 4 and 7, 4 and 8, 4 and 9, 4 and 10 => 65 and 6, 5 and 7, 5 and 8, 5 and 9, 5 and 10 => 56 and 7, 6 and 8, 6 and 9, 6 and 10 => 47 and 8, 7and 9, 7 and 10 => 38 and 9, 8 and 10 => 29 and 10 => 1Then Total mixtures possible are =
9 + 8 + 7 + 6+ 5 + 4 + 3 + 2 + 1

Primary and secondary succession why and how do they happen and what occurs during each?
Explanation:
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
What control showed that transformation and not conjugation or transduction was responsible for the results
When we talk of transformation,we are talking of a biological method of the alteration of gene in a living cell especially as seen in a bacterial cells.
As a result of the incoperation and uptake of foreign genetic material from it's surrounding, the said bacteria then takes up the exogenous DNA,this it does by binding it with specific receptors that are present in its cells membrane or it can do so through diffusion.
However,the foreign DNA will either get incorporated in the DNA of the host chromosome or it will act like a plasmid and them express itself in the cell of the new host.
Then in conjugation,we see the transfer of circular plasmid DNA,this is transferred from one bacterium to another and it is done through cell to cell contact.
Also, transduction is still another way of transferring genetic materials,here the DNA is transferred to another bacteria via bacteriophage through lysogeny.
Now,in a given experiment,to identify if the reaction is transformation and not configuration and transduction,a controls sample will be provided,this control sample will contain DNase coupled with the reaction mixture,if there is a revelation of an exogenous DNA by the test sample,and there is no expression by the control,then we know that is transformation,we know it is transformation because DNase cleave free DNA and it will not be able to cut the DNA that is present inside the cell of donor bacteria that is in conjugation or bacteriophage(transduction).
Therefore,the addition of DNase in control sample can determine if the transfer of genetic materials in the test samples is transformation and not transduction or conjugation.
Why is phenylketonuria resulting from dihydropteridine reductase deficiency a more serious disorder than PKU resulting from phenylalanine hydroxylase deficiency?
Answer:
pteridine reductase deficiency alters all reactions known to be dependent on tetrahydrobiopterin (BH4)
Explanation:
Hyperphenylalaninemia is a condition characterized by elevated concentrations of the amino acid phenylalanine in the blood. Dihydropteridine reductase deficiency (DHPR) is a severe type of hyperphenylalaninemia caused by the deficiency of tetrahydrobiopterin (BH4). BH4 helps to convert amino acids, including phenylalanine, to precursors of neurotransmitters. BH4 is an essential non-protein co-factor of enzymes associated with the biosynthesis of dopamine, serotonin, noradrenaline and adrenaline. DHPR is an inherited recessive disorder whose symptoms include mental deficiency, poor swallowing (dysphagia) and an abnormally small skull (microcephaly).

If you are a diploblastic animal, you have:__________ A. mesoderm. B. radial symmetry. C. a coelem. D. a mouth that developed from the blastopore. E. all of the above
Answer:
C. Radial Symmetry
Explanation:
Diploblastic Animals are those animals whose blastula have basically two primary germ layers. These layers are called the endoderm and the ectoderm. On the contrary, most other animals have three layers found in them. The endoderm is an embryonic germ layer that gives rise to the gut. They also give rise to the tissues that form the internal organs. On the other hand, the ectoderm produces skin and nervous tissue and does cover the outside of the embryo. This type of body plan is particularly seen in cnidaria and ctenophora
