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.

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:

The 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.

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.

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.

Switching from coal to natural gas or nuclear energy to generate electricity will lessen human impacts on the global climate.

It is the changes to climate brought about by anthropological emission of greenhouse gases.

Greenhouse gases are emitted from human actions such as the burning of coal, removal and burning of forest layers, etc.

Thus, in order to lower human impacts on climate, replacing activities such as the burning of coal with clean technology such as nuclear energy to generate electricity would go a long way.

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

Answer:

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.

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

Explanation:

Answer:

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, leading to major flaws in the DNA replicated for cell division. This could lead to large-scale errors and result in the organism's death.

Answer: Glucose

Explanation: Glycogen is a large, branched polysaccharide that is the main storage form of glucose in animals and humans. Glycogen is as an important energy reservoir; when energy is required by the body, glycogen in broken down to glucose, which then enters the glycolytic or pentose phosphate pathway or is released into the bloodstream. Glycogen is also an important form of glucose storage in fungi and bacteria.

Explanation:

I do not think it is possible because plants do photo synthesis in a organelle called chloroplast which humans do not have.

Answer:

Oxygen, origin of plants and chloroplast.

Explanation:

The oxygen present in our atmosphere was generated by various species of cyanobacteria during the Archaean and Proterozoic Eras. origin of plants on the earth is other great contribution of the cyanobacteria. The chloroplast which is present in plants due to which they make their own food is actually a cyanobacterium living within the plant's cells.

Explanation:

In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.

Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration .

Answer:

Reflex action/reflex arc/reflex (allow "involuntary") The stimulus (heat) is detected by temperature receptors in the skin. This causes impulses to travel along a sensory neurone to the spinal cord, due to chemical changes across the synapses. Here they go along a relay neurone, and then are sent via a motor neurone to the effector (an arm muscle in this case). The muscle contracts, moving the hand away and preventing further harm.

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)

Answer:

D. Dresser

Explanation:

According to the unified cell theory "all living organism are made of one or more small cells" and new cells arise from one cell through cell division.

From the given examples, the best model for a group of cells from a plant is "dresser" because a cell is consist of small structures called organelles that perform specialized functions likewise a dresser can contain several objects that can act as organelles.

Hence, the correct answer is "D. Dresser".

The cell theory states that:

a) all living organisms are made up of cells

b) cells are the basic structural and organizational unit of life

c) all cells arise from pre-existing cells.

From the three statements above, all living organisms fall into the categories hence from the list, all the living organisms (Kitten, mushroom, bacteria, and cactus) are made up of cells. While rocks are non-living hence they are not made up of cells.

Answer:

All except for rock
