Based on this diagram label the positive and negative sides of the DNA fingerprint with a + and – sign.
Answers
We can say that the top of the gel, where the DNA samples were applied, is the negative side, while the bottom of the gel is the positive side.
We can arrive at this answer because:
DNA is a negatively charged molecule.For this reason, when DNA is applied in an electrophoresis vat, it must be placed in the negatively charged portion.This is because the electrophoresis vat will allow an electrical discharge to pass through the vat and drag the DNA from the negative side to the positive side.This movement allows the DNA to present a series of fragments of different sizes that will be observed in a fingerprint, such as the one presented in the question above.
In the figure below you can more accurately see the positive and negative sides.

Which of the following is an advantage of sexual reproduction?
A. Produce identical copies of an organism.
B. Produce natural variation to adapt to environmental change.
C. Quickly populate a new habitat.
D. Reproduce very quickly.
Answers
Answer:
B
Explanation:
Produce natural variation to adapt to environmental change is an advantage of sexual reproduction. Correct Option is 2.
The advantage of sexual reproduction is that it produces genetic variation within a population. During sexual reproduction, offspring inherit a combination of genes from both parents, leading to unique genetic combinations. This genetic diversity results in natural variation among individuals within a population.
This variation is advantageous because it allows a population to better adapt to changing environmental conditions. In a changing environment, some individuals may possess traits that are better suited to the new conditions, making them more likely to survive and reproduce. Through natural selection, these advantageous traits can become more prevalent in the population over time, enhancing the population's overall ability to adapt and thrive.

what factors determine if a species is fit to survive?
Answers
Answer: variation, reproduction, and heritability.
Explanation: Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.
Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.

c. Neither parent carries the allele for color blindness.
d. The father carries the allele for color blindness.
e. The mother carries the allele for color blindness.

If it’s a recessive allele 1 parent isn’t enough, both parents have to have the recessive allele, and even then it’s a small chance. Hope this helped ^^

the allele for color blindness.
A trait could either be:
DominantRecessiveWhat is a Recessive trait?A recessive trait is usually expressed when there is the presence of two
recessive alleles in an individual or organism. A dominant trait on the other
hand can be expressed with the organism having only one dominant allele
In this scenario, the red green color is a recessive trait
and the offspring produced is color blind which basically means that both
parents carry the allele for color blindness.

a/an ___ is a blood clot attached to the interior wall of a vein or artery.
Answers
Answer: a thrombus
A thrombus may also form in your heart
A thrombus is a blood clot attached to the interior wall of a vein or artery, which is option a. So the correct option is option a, as thrombus formation occurs when blood coagulation factors are activated and form a clot within a blood vessel.
Thrombi can occur in veins (venous thrombosis) or arteries (arterial thrombosis). In veins, a thrombus can lead to deep vein thrombosis (DVT), which commonly occurs in the lower extremities. If a thrombus dislodges from its site of origin and travels through the bloodstream, it is called an embolus, and it can potentially cause an embolism in another location. So the correct option is option a.
