Answer:B- drains excess instertial fluid

Explanation:lymphatic system is a network of drainage that helps keep bodily fluid levels in balance.

Lymphatic system helps in conduct of lymph and also protect the body against infections.

It is made up of a network of lymphoid organs, lymph nodes, lymph ducts, lymph tissues, lymph capillaries

The lymphatic system, Functions by absorbing fluids that could leak from capillaries.

They also Absorb fatty acids and aid transport of fat to the circulatory system. Production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells)are done by lymophocytes

solong [7]

Damage to heart valves can lead to heart murmur.

Explanation:

Heart murmur refers to the sound of blood flow. The sound of flowing blood in the heart is usually not heard.

What is true about the function of the electron transport system (ETS)?
FrozenT [24]

The correct answer is the last option.

The first option does not make sense as the electron transport chain makes the most ATP from the whole ATP synthesis cycle including glycolysis and the Kreb's Cycle. It also does not make NADH, but instead splits NADH into NAD- and H+. The H+ are used later to make ATP.

The second option also does not make sense as a "lysosome" is a digestive "pocket" in the cell, used for taking in and digesting food for the cell.

The third option also does not make sense as it does not produce NADH and is not during glycolysis. The electron transfer chain breaks up NADH and FADH2 and is the last step in the ATP synthesis process, after glycolysis and Kreb's Cycle.

The last option is correct. The electron transfer chain has the ability to make 34 molecules of ATP (in theory; so in real-life this does not always happen). The electron transfer chain does break down several compounds derived from glucose in a series of chemical reactions that do occur in the cristae of the mitochondrion.

Bogdan [553]

Answer:

- production of vaccine for disease prevention

- production of genetically modified crops

Explanation:

Recombinant DNA is a special type of DNA that has been infused with a foreign gene of particular interest.

With recombinant DNA technology, scientists can study different proteins and see how they can be used for therapy in the area of medicine. <em>The technology has been used to produce several vaccine in the prevention of diseases.</em>

In addition, recombinant DNA technology has been useful in agriculture to produce <em>genetically modified crops with desired traits such as resistance to pests/diseases and high yields.</em>
