What is Gram staining?Gram staining may be defined as a methodology that is utilized for the classification of bacterial species such as gram-positive and gram-negative.
In gram staining, ethyl alcohol or acetone is used as a decolorizer that dehydrates the peptidoglycan layer. It involves the shrinkage or tightening of the cell wall.
In this process, the large crystal violet-iodine complex is not able to puncture this tightened layer of peptidoglycan.
Therefore, the correct option for this question is A.

Passage
The diagram shows part of a grasshopper's respiratory system. Air passes into and out of openings in its sides. These openings are connected to tubes and air sacs that fill with air. The air tubes branch into tiny tubes that spread out and are found close to all cells. So, unlike other animals, the grasshopper does not exchange gases using its circulatory system.
PLS ANSWER ASAP
Answer:
In vertebrates, the circulatory system is responsible for transporting oxygen to all the tissues and removing carbon dioxide from them. ... In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process.

Oligomycin A is an antibiotic that works by blocking a proton (H ) channel in ATP synthase, inhibiting the action of the enzyme. The primary effect of this antibiotic is: Group of answer choices decreased ATP synthesis due to a decreased hydrogen ion gradient across the inner mitochondrial membrane. increased ATP synthesis due to an increased hydrogen ion gradient across the inner mitochondrial membrane. decreased ATP synthesis due to the inhibition of oxidative phosphorylation of ADP. increased ATP synthesis due to the promotion of oxidative phosphorylation of ADP.
Answer:
Decreased ATP synthesis due to the inhibition of oxidative phosphorylation of ADP
Explanation:
If the antibiotic inhibits the action of ATP synthase, it will decrease ATP synthesis.
ATP synthase has the main function of synthesizing ATP from the oxidative phosphorylation of ADP.
In oxidative phosphorylation, ATP is produced from the transfer of electrons from NADH and FADH2. A chemical gradient is created, allowing for ATP synthase to create ATP.
So, the correct answer is that there will be decreased ATP synthesis due to the inhibition of oxidative phosphorylation of ADP.

Hemophilia A and red-green color blindness are examples of X-linked recessive diseases. Color blindness to red and green. Red-green color blindness prevents a person from recognizing red and green hues (usually blue-green). Otherwise, though, they can see normally. Thus, option C is correct.
What allele for color blindness located on X chromosome?Females have two X chromosomes, while males have one X and one Y chromosome. The X chromosome is where the genes that might cause red-green color blindness are handed down. Men are more likely than women to have red-green color blindness, since it is X-chromosom-inherited.
One of the most prevalent genetic (inherited) disorders in the world is color blindness, which means it is typically inherited from your parents.
Therefore, the allele for color blindness is located on the X chromosome, color blindness is sex-linked.
