Answer:

a. the coordinated control of gene expression in bacteria

Explanation:

An operon in bacteria is a collection/cluster of genes that are under the control of a single promoter. It includes 3 components: a promoter, the genes and an operator. The operator is where a repressor binds, and the promoter is where transcription begins.

Operons allow organisms to control the expression of multiple genes in response to environmental cues

The pulmonary circulation conveys blood that is ______ in oxygen to the lungs before returning back to the ______ side of the he
Oduvanchick [21]

The pulmonary circulation conveys blood that is low in oxygen to the lungs before returning back to the left side of the heart.

<h3>The pulmonary circulation</h3>

The circulatory system is divided into two main parts namely:

  • pulmonary circulation and

  • systemic circulation.

The pulmonary circulation involves the movement of blood between the lungs and the heart.

Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.

After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.

What is the protein recommendation associated with resistance training for younger adults to increase muscle protein synthesis?
Mademuasel [1]

Whey protein and milk are recommended for muscle protein synthesis in young adults during resistance training.

<h3>What is muscle protein synthesis? </h3>

The metabolic process in which new amino acids are attached to the bound proteins of skeletal muscle is called muscle protein synthesis.

Whey protein is a great choice of consumption for muscle protein synthesis because it contains a high amount of leucine. Milk and dairy products are rich sources of whey protein.

Therefore, the consumption of whey supplements and milk is recommended for increasing muscle protein synthesis in young adults.

nydimaria [60]

Answer:

B)

Explanation:

The more force the swimmer applies back on the wall, the faster his movement forward in the water. Newton's third law states that for every action there is an equal and opposite reaction. Not all the statements are false; they just do not describe Newton's throw law of motion.

Alex Ar [27]

Answer:

b. Pollen tubes did not enter all of the ovules in such pods

Explanation:

Quite sometimes, ovules fail to mature seeds because most of their flowers do not receive enough pollen to fertilize all of their ovules and are eventually aborted, thereby resulting in some ovules becoming mature seeds and others do not get matured.
