The statement that is NOT correct is c. A single, unamplified copy of DNA is sufficient to detect a mutation. This is because the detection of a mutation requires amplification of the DNA sample using techniques such as polymerase chain reaction (PCR) to increase the amount of DNA available for analysis.
This is necessary because the amount of DNA in a single human cell is not sufficient for detection and analysis. Therefore, a small amount of sample DNA is subjected to PCR prior to DNA typing to ensure that there is enough DNA to detect and analyze any mutations or variations.
The other statements are correct and explain why DNA typing is a useful tool for identifying individuals and understanding genetic conditions. DNA is present in the nuclei of every human cell, and a DNA sample obtained from these cells contains the entire human genome.
It is also possible to examine a relatively small region of DNA if testing for a specific genetic condition, and a small amount of sample DNA is subjected to PCR prior to DNA typing to increase the amount of DNA available for analysis.

Which explanation best identifies the relationship between mitosis and
reproduction? *
Mitosis is a form of sexual reproduction because the daughter cells form from one
single parent cell.
Mitosis is a form of sexual reproduction because the daughter cells are genetically
different from the parent cell.
Mitosis is a form of asexual reproduction because the daughter cells form a new
nuclear membrane after reproduction.
Mitosis is a form of asexual reproduction because the daughter cells are genetically
identical to the parent cell.

what happened to the
beak depth of finches born in 1978 compared to those born in 1976? Explain why you
think this occurred.
Answer:
Why do you think the average beak depth of the birds increased?
Explanation:
Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

Give the one chain to the following DNA AATAGGTACCCATGTGCA To write the complementary dna chain. How many nucleotides does this molecule have in total? How many are the bonds that unite nucleotides together?
Answer:
AATAGGTACCCATGTGCA (original DNA sequence)
TTATCCATGGGTACACGT
Explanation:
Adenine (A) pairs with Thymine (T). Guanine (G) pairs with Cytosine (C). There are 18 nucleotides in this sequence, as seen by the number of base pairs there are. Hydrogen bonds hold together the matching base pairs.
How many times more erosion occurs in a soil with 3% moisture than a soil with 7% moisture is a 15 m s-1 wind?
Answer:
Twice.
Explanation:
If a soil with 3% moisture has twice the rate of erosion as compared to the soil having 7% moisture if both experience same speed of wind i. e. 15 m/s. This is because moisture held the particles of soil tightly with each other and prevent erosion in the soil so if the moisture becomes half in the soil then the rate of erosion is twice or doubled at constant wind speed.

Which stage of mitosis occurs the least often and why?
Explanation:
The Anaphase stage is the shortest phase of mitosis. During this phase, disjunction occurs, and migration of sister chromatids away from each other to the poles of the cell occurs, leading to the formation of daughter chromosomes. Molecular motors use ATP to shorten the spindle fibers attached to each sister chromatid

The lineage of pea plants produced round seeds for four generations. The plants that fertilized these pea plants also produced round seeds. However, in the fifth generation, the plant produced to two plants with wrinkled seeds. Can that be possible? Explain your answer using your pedigree chart.
Answer:
Explanation:
This happened because two fully recessive plants where introduced into the lineage. these plants where paired with the dominate verison. this would make all of the offspring have the two traits. this being said it would make it possible for the offspring to be Wrinkled Seeds.
When two heter0zyg0us individuals are crossed -simple d0minant inheritance-, or a heter0zyg0us individual is crossed with a h0m0zyg0us recessive one, they can produce h0m0zyg0us recessive subjects among the progeny. Heter0zyg0us individuals among the fourth generation got crossed with another plant (h0m0zyg0us recessive or heter0zyg0us) and produced two h0m0zyg0us recessive plants expressing wrinkle seeds.
---------------------------
The first step is to understand the given information. So,
The first four generations produced round seedsPlants that fertilized these plants also produced round seeds (see generation II) Among the fifth generation there are two plants with wrinkled seedsLet us assume that a diallelic gene determines the shape of seeds.
D0minant allele R codes for round seedsRecessive allele r codes for wrinkle seedsNow, let us analyze the pedigree. According to the information provided here, we can tell that
black figures represent h0m0zyg0us d0minant individuals, grey figures represent heter0zyg0us individualsempty figures represent h0m0zyg0us recessive individualsRemember that Generations are represented with roman numbers.
We will name the plants with numbers from 1 to 26.
According to the information in the statement and the information in the pedigree, we can say that grey individuals from the fourth generation are heter0zyg0us expressing round seeds. They can produce wrinkle seeds, if they are fertilized by another heter0zyg0us plant or a h0m0zygous recessive one.
Option 1:
Two heter0zyg0us plants are crossed, and their offspring have wrinkled seeds.
Option 2:
One heter0zyg0us plant is crossed with a h0m0zyg0us recessive one, and their offspring have wrinkled seeds. Let us see the cross

How do living organisms maintain homeostasis within their bodies?
Answer:
The body regulates those levels in an example of homeostasis. When levels decrease, the parathyroid releases hormones. If calcium levels become too high, the thyroid helps out by fixing calcium in the bones and lowering blood calcium levels. The nervous system helps keep homeostasis in breathing patterns.
