Explanation:

Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

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.

Answer:

25 hours

Explanation:

Speed is a measure of the distance traveled by a body relative to the time taken to complete a trip or a journey. Mathematically, speed can be expressed as;

      speed = distance/time

Hence, time = distance/speed

The distance covering Dallas, Texas, to Salt Lake City, Utah is about 1500 miles and the speed limit is 60 mph, hence;

time = 1500/60

           = 25 hours

Therefore, the least amount of time that would be needed to cover the journey is 25 hours.

Answer:

25 hours is your answer

Explanation:

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.

Water covers most of Earth's surface

Explanation:

I chose Water covers most of Earth's surface because this is a fact, NOT a unique property. A property is a thing the item has.

Mitosis aims to create daughter cells that are completely genetically similar to their mothers, with no extra or less chromosomes. In contrast, meiosis serves a single function in the human body that is the creation of gametes.

The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.

Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.

Grow in the absence of signals instructing them to do so in cancer cells. Only when they get such signals do normal cells expand. Disregard cues that would typically instruct cells to cease dividing or die.

Aneuploidy is a condition when there are either too many or too few chromosomes in the daughter cells produced during mitosis.

Thus, this is the overall purpose of mitosis and meiosis.

1. The overarching goal of mitosis is to ensure cell division and the transfer of genetic material to daughter cells for tissue repair, growth and development.

2. To maintain genetic integrity, DNA replication is necessary prior to cell division.

3. Cancer cells have uncontrolled growth, escape cell death and lack contact inhibition, whereas normal cells have controlled cell division, experience programmed cell death and show contact inhibition.

4. The disorders in humans can result from errors in the cell cycle. Diseases such as Down syndrome are caused by abnormal chromosomes. Gene changes can affect the development of cancer.

Meiosis produces gametes for sexual reproduction, while mitosis assures cell division for growth, development, and tissue repair. Accurate transmission of genetic information and preservation of genetic integrity in daughter cells depend on DNA replication prior to cell division.

Whereas cancer cells have uncontrolled proliferation, escape from cell death, and lack contact inhibition, normal cells have regulated division, programmed cell death, and appear to have contact inhibition. Human disorders such as chromosomal abnormalities (such as Down syndrome), gene mutations that cause cancer, errors in DNA replication or repair that cause genetic disorders, and cell cycle control that leads to uncontrolled cell division and tumor formation, all of which Mistakes made during this can have consequences. cell cycle.

Answer: a. Glucose is broken down to pyruvate.

b. Respiration requiring oxygen occurs in the mitochondria.

Explanation:

Cellular respiration can be defined as the process in which oxidation of food occurs in the mitochondria and energy is released as ATP. The glucose which is six carbon molecule is most common substrate for oxidation and it is converted into pyruvate which is a three carbon molecule. This is occurs in aerobic cellular respiration. During cellular respiration 30+ ATP molecules are produced which is comparatively more than glycolysis and Kreb's cycle.

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.

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.

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:

Antibiotics are not effective for new strains and so new resistant pathogens survive and reproduce, which leads to the increasing population of resistant pathogens and spread rapidly.

Bacteria can evolve and adapt themselves quickly as they are able to reproduce at a fast rate. Mutations of bacteria produce new strains that are resistant to certain antibiotics, such as penicillin, and cannot be destroyed by the antibiotic so they spread more rapidly.
