The Punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. Which Punnett square

represents a cross between a mom who is heterozygous for dimples and a dad who is homozygous for no dimples?
A Punnett square is shown. The columns are labeled Upper D and Upper D. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, Upper D d, Upper D d, Upper D d.

Answer:

A Punnett square is shown. The columns are labeled Upper D and d. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, d d, d d, Upper D d.

Explanation:

Punnett square is used to depict the cross between two organisms. Progeny genotypes can be determined by punnett square. Columns and rows are labelled according to the alleles present in the genotype of respective parents, in this case the mom and the dad.

It has been given that the mom is heterozygous for dimples trait. Since, heterozygous genotype has two different alleles together, mom's genotype must be Dd. Dad is homozygous for no dimples so he can either be DD or dd depending on the dominance nature of the trait. Out of the given options, only the selected option has one heterozygous genotype (Dd) and one homozygous genotype (dd) together hence it is the correct option.

Assume that one of the disinfectant/antiseptics tested using the disc method had a clear zone of inhibition and to your surprise
o-na [289]

The presence of the minute growth near the disc signifies that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances.

<h3>What are zones of inhibition?</h3>

The sensitivity testing in a microbiology laboratory is done to determine the effect of antibiotics on various bacteria organisms

The zone of inhibition when a disk method is used signifies the area of media where bacteria are unable to grow, due to presence of a drug that impedes their growth.

If there are presence of minute growth near the disc, it means that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances such as disinfectants.

If these mutant bacteria organisms are not cleared by the disk method, it means that they cannot be killed by the disinfectant/antiseptics that is being tested.

Damm [24]

Answer:

This will lead to an  decreases  in the ATPs synthesis. This is because low pH , high acidity favours ATP synthesis, because it increases the  proton concentration for electrochemical gradients needed for energy that  ATPase enzymes makes used of   synthesis  of ATPs.

Therefore a rise in the pH(low acidity) lowers protons levels, and therefore reduced electrochemical gradients , with a drop in energy for ATPs synthesis.

Kipish [7]

Answer:

Columnar epithelial tissue.

Explanation:

The above scenario confirms that these are simple columnar epithelial tissue because columnar cells are tall, narrow and nucleus in the tall column like cells located at the basal end of the cells. Columnar epithelial tissue are responsible for absorption and secretion of molecules. These are present at some part of digestive tract, female reproductive tract, and respiratory system.
