Select one:
A) Decreasing research of all wind or water-based electricity generation technologies
B) Switching from coal to natural gas or nuclear energy to generate electricity
C) Increasing electricity production from coal
D) Banning any form of carbon emissions trading programs
Switching from coal to natural gas or nuclear energy to generate electricity will lessen human impacts on the global climate.
What is climate change?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:
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.

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.

the series of events in the nervous system which causes Miriam to react thi
way
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.

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

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

In facilitated diffusion, molecules move down their concentration gradient.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 .
