Answer:
Blood type is an example of ✔ codominance
Explanation:
Blood type is determined by the ✔ antigens on the blood cells.
✔ Antibodies attack foreign blood that does not contain the same antigens.
Blood type is an illustration of codominance.
What is blood type?Blood group also known as blood type refers to classification of blood on the basis of the absence and presence of antibodies and inherited antigenic components on the red blood cells surface. These antigens may be:
ProteinsCarbohydratesGlycolipidsGlycoproteinsThe blood type in humans is an example of codominance. In codominance, neither of the allele can inhibit the expression of the other allele. One of the example is the ABO blood group in humans. In this, both the alleles A and B are expressed.
Therefore, if a person is inheriting allele A from the mother and allele B from the father, he or she will have the blood type AB.
Thus, blood type is an example of codominance.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answer:
Phenotype: 3 black mice: 1 brown mice
Genotype: 1 BB: 2Bb: 1bb
Explanation:
This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.
If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, Bb, Bb, and bb
- The phenotypes of this cross is 3 black mice: 1 brown mice
- The genotypes of the cross is 1 BB: 2Bb: 1bb

In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.
Answer:
This question is incomplete, however, it is asking to identify the following variables:
Independent variable: Temperature
Dependent variable: Number of yeast cells
Constants: same amount of nutrients, same number of yeast cells, same medium
Explanation:
- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.
- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.
- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.

14. To cause cancer, proto-oncogenes require 2 allele(s) to be mutated and therefore are considered recessive. The mutation results in a gain of function.
15. To cause cancer, tumor suppressor genes require 2 allele(s) to be mutated and therefore are recessive. The mutation results in a loss of function.
The image below shows the cell cycle with checkpoints indicated in red. What will most likely happen if the cell finds a mistake at one of the checkpoints?
Answer:
I think it may be A. the cell will prevent division from occurring
The most likely to happen if the cell finds a mistake at one of the checkpoints is the cell will prevent the division from occurring. The correct option is A.
What are checkpoints in cell division?Cell cycle checkpoints are processes that monitor the sequence, integrity, and fidelity of the cell cycle's fundamental events. These include cell development to the optimum size, chromosomal replication and integrity, and correct segregation at mitosis.
The cell that divides to produce two daughter cells is known as the mother or parent cell in the process of cell division. Mitosis produces two offspring cells that are genetically identical to the mother cell. The cell cycle has four checkpoints. These are G1, S, G2, and M.
Therefore, the correct option is A. the cell will prevent the division from occurring.

Explanation:
biotic factor means something alive is in the factor. all the others are abiotic factors
The biotic factor is a living factor providing a source for ecosystem development, hence option b algae in the water are the correct option.
What is a biotic factor of a freshwater pond?A biotic factor is a live entity that influences its surroundings. Aquatic plants, fish, amphibians, and algae are all examples of freshwater ecosystems.
A biotic factor is a live entity that influences its surroundings. Aquatic plants, fish, amphibians, and algae are all examples of freshwater ecosystems.
Turbulence, temperature, water clarity, habitat size, and water depth all influence the structure and function of ponds and lakes. Temperature interacts to affect lake stratification and water circulation.
Therefore algae that balance the aquatic ecosystem is a major abiotic factor, hence option b in water-growing algae is correct.

What is the graphical representation of age structure known as?
OA.
age group
OB. age graph
Oc. age scale
OD
age pyramid
Answer:
The graphical representation of the age structure is known as age pyramid (option D).
Explanation:
The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.
The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.
In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.
Age group, age graph or age scale do not correspond to the population graph where the age and sex structure of a population are expressed.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answer:
The correct answer is -
Phenotype: 3:1 (dominant black mice: recessive brown allele)
genotype: 1:2:1 (purebred dominant : heterozygous: purebred recessive)
Explanation:
In the given question there is a cross that takes place between two heterozygous black mice. LEt assumes B is black which is the dominant allele and b is the recessive allele or brown. As it is given in heterozygous condition black mice are present which means the B is dominant over b.
Now cross:
Gametes: B and b for each mice
B b
B BB Bb
b Bb bb
By the cross, there are two phenotypic offspring that produce 3 black mice out of four and 1 brown or recessive allele out of four
And, genotypically three offspring in the ratio of 1:2:1 (purebred dominant : heterozygous: purebred recessive)

DNA polymerase is an enzyme required in DNA replication. Its role is to synthesize DNA, adding individual nucleotides to each strand of newly synthesized DNA with the help of other enzymes such as primase and ligase. There are several families of DNA polymerase in both prokaryotes and eukaryotes, but through different species, portions of DNA polymerase are highly conserved. What do you think is the evolutionary significance of DNA polymerase? What do you think would happen if there was a genetic mutation on the genes encoding for DNA polymerase?
A sample answer would look like this: The DNA polymerase has evolutionary significance because it is required for DNA to be transmitted across generations. A genetic mutation in a gene encoding for DNA polymerase could lead to significant flaws in DNA replication, which could lead to major flaws in the DNA replicated for cell division. This could lead to large-scale errors and result in the death of the organism.
Answer:
Abstract. DNA polymerase I (pol I) processes RNA primers during lagging-strand synthesis and fills small gaps during DNA repair reactions. However, it is unclear how pol I and pol III work together during replication and repair or how extensive pol I processing of Okazaki fragments is in vivo
