Answer:
QTLs can be identified by using molecular markers associated with the variation of the trait
Explanation:
A Qualitative Trait Locus (QTL) is a chromosomal region correlated with the variation of a quantitative trait, i.e., a phenotypic trait controlled by many genes. QTL mapping refers to the identification of QTLs associated with a particular trait. In QTL mapping, molecular markers (i.e., small and identifiable DNA fragments) are used to develop genetic linkage maps which are further used to discover QTLs. This technique (QTL mapping) consists of evaluating the phenotypic segregation of the trait in the progeny by statistically correlating phenotypes with patterns of genetic segregation (segregation of the molecular markers).

how are logistic and exponential growth similar?
Answer:
because both are same words
Explanation:
Answer:
Both growth models begin with a population that is growing at a constant rate.
Logistic growth follows a period of exponential growth, as population growth slows or stops.
Exponential growth is only possible when resources are unlimited.
Logistic growth shows what happens when resources become scarce and population growth slows.

leads to movement in the
Intense heat at Earth's core creates movement in the mantle, which in turn leads to movement in the crust as the earth has three layers, such as the innermost core and the outermost crust layer.
What is the significance of the earth's layers?The earth is composed of several layers, each with unique properties and characteristics, such as the core, mantle, and crust, the core is made up of two layers: the inner core and the outer core, while the inner core is made up of solid iron and nickel and the outer core is a liquid layer of iron and nickel, the mantle is the thickest layer of the earth and is made up of solid rock present outside of the core, and the crust is the outermost layer of the earth and is made up of solid rock.
Hence, intense heat at Earth's core creates movement in the mantle, which in turn leads to movement in the crust as the earth has three layers, such as the innermost core and the outermost crust layer.

DNA is composed of two complementary strands this is reflected in the fact of that
Answer: The number of adenines in one strand is equal to the number of thymines in the complemetary strand.
Explanation:
Deoxyribonucleic acid or DNA is a molecule that contains the genetic information in all living organisms. So it contains all the hereditary genetic information that has the instructions to development. This DNA molecule consists of two strands that bond together to form a double helix structure. Each strand of DNA is made up of nucleotides which are basic chemical components made of a phosphate group, a sugar group and one of four types of alternative nitrogenous bases. The four types of nitrogenous bases found in the nucleotides are:
Adenine (A)Thymine (T)Guanine (G) Cytosine (C).The sequence of these bases determines how genes are made, and each gene has different biological instructions to create proteins (that will have different functions in the organism). To form a DNA strand, the nucleotides are linked together in chains, alternating with the phosphate and sugar groups.
The nitrogenous bases are complementary between them. Adenine and thymine are complementary, as are guanine and cytosine. So since adenine is complementary to thymines, and cytosine is complementary to guanine, the number of adenines in one strand is equal to the number of thymines in the complemetary strand. And the number of cytosine is equal to the number of guanine.
DNA is composed of two complementary strands this is reflected in the fact of that - The amount of adenine in one strand is always equal to the amount of thymine in the complementary strand.
A stable double helix of DNAthe two strands of DNA are antiparallel which means if one strand is, the 5' → 3' direction of one strand runs opposite to the other strand.The two DNA chains are held together by complementary base pairing between A and T bases and between G and C bases.The hydrogen bonds are found between the bases of the two strands of nucleotides.Adenine forms hydrogen bonds with thymine whereas guanine forms hydrogen bonds with cytosine.This is called complementary base pairing.
Thus, DNA is composed of two complementary strands this is reflected in the fact of that - The amount of adenine in one strand is always equal to the amount of thymine in the complementary strand.

What would most likely happen to plant cells if the plant was watered with salty water?
A. Water will enter the plant cells until the large central vacuole bursts
B. The plant's root will filter out the right amount of salt so the plant can remain isotonic.
C. Salt crystals will form on the leaves as water evaporates on the leaf surface.
D. Water would leave the large vacuole of the cell and the plant will droop.
Answer:
option D
Explanation:
the plant will lose water because water moves out of the cell and the vacuole will leave the cell
Water would leave the large vacuole of the cell and the plant will droop if it was watered with salty water.
What is Vacuole?This is referred to as an organelle within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid.
In cases where the plant is watered with salty water, osmosis takes place which involves water leaving the vacuole and the plant drooping thereby making option D the most appropriate choice.

What causes nucleotides to switch locations in a DNA molecule?
Answer:
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.
Explanation:
You read an article on a website that suggests that there may be a new form of cancer-causing mutagen that causes the DNA backbone structure to be disrupted in its normal sequence. Using your knowledge of the structure of the DNA molecule, explain how you might hypothesize such a mutagen might impact the ability for the DNA molecule to do its job effectively.
Answer:
The mutagen might alter the DNA sequence, thereby altering the accessibility to transcription factors and thus activate the expression of oncogenes involved in cell proliferation
Explanation:
The DNA molecule consists of two antiparallel strands of nucleotides that wind around each other. Each DNA strand is formed by a backbone containing sugar (deoxyribose) and phosphate groups. This arrangement allows for DNA replication and transcription (and consequently also protein synthesis) to occur. If a mutagen agent binds to DNA, this might modify its structure, thereby altering DNA replication and transcriptional activity.

b. only when nonrandom mating occurs.
c. a new genetic variation occurs that allows individuals to have a reproductive and survival advantage.
d. when a small number of individuals of a population break away and form a new population.
Answer: The correct option is C.
a new genetic variation occurs that allows individuals to have a reproductive and survival advantage.
Explanation:
It is a new genetic variation occurs that allows individuals to have a reproductive and survival advantage because natural selection is a survival mechanism in which organisms develop a variation in genetic traits or develop characteristics which help them to reproduce,survive,adapt to their environment and pass on these characteristics to their offsprings which can be transfer to generations.
