In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?

Answers

Answer:

100 %

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).

A scientist wants to determine the best light wavelength for growing plants. He grows plants in four test groups as shown in the table below. What, if anything, was wrong with the experiment?

A. He should only grow one plant in each group.
B. He should only change the wavelength of light for each group.
C. He should add a control group with a CO2 level of zero ppm and a light intensity of zero percent.
D. There is nothing wrong with the experiment.

Answers

Answer:

The correct answer is - option B. he should only change the wavelength of light for each group.

Explanation:

In any experiment or research, there should be only one variable that needs to change to see the effect of that variable on the dependent variable and other variables should be constant so there no other variables could influence the result of the experiment.

In this experiment, there is two variable are manipulated that are the different wavelength of light which is desired variable or independent variable in this experiment but CO2 level also changes in each group which should be constant but now it affects the experiment.

Cells use a molecule called (DNA / RNA / ATP / CMP) to store and release energy like a battery. The energy is stored in chemical bonds between (nucleotide / oxygen / phosphate / ribose) groups of the molecule, and the energy is released when the chemical bonds are broken.

Answers

Answer:

Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.

Explanation:

The Adenosine Triphosphate (ATP) is a molecule made of adenine, ribose, and three phosphate groups, which are the ones that store the energy in its bounds.  The ATP is the molecule that provides the energy to the different processes that happen in a cell. The molecule is made from the glycogen, fats, and carbohydrates that the body has absorbed in the intestines. When the body needs energy, the ATP loses one or two phosphates, becoming ADP and AMP. When the phosphorylation happens, which is the loss of phosphate, the energy is released.

In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%

Answers

Dd is crossed over with dd.
So, as we set the punnet square. We get (2)Dd and (2)dd. So 100/2 = 50%.
Correct choice - C 50%.

The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.

What are alleles?

The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.

It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.

Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.

Dd is crossed by dd.

100 / 2 = 50%.

Therefore, the correct option is C.
