Explain how prokaryotic and eukaryotic cells are similar
STatiana [176]

Answer:

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

Distance runners include aerobic training as part of preparation for races. How does this impact their cellular respiration?
Misha Larkins [42]

Answer and Explanation:

Running or jogging comes under the category of aerobic training/exercise. By definition, aerobic exercise means that the person is training her/his body in the presence of excessive oxygen. So, metabolically speaking, the person is relying on availability of oxygen to carry out metabolism which is mainly about production/supply of energy (ATP) by the breakdown of food in the presence of oxygen. This process is also known as cellular respiration. So, if a person is doing aerobic exercise (running), s/he needs more energy to keep doing the exercise. Typically, aerobic exercise produce more energy (32 molecules of ATP) as compared to anaerobic process (2 molecules of ATP) per reaction run. Thus, In the process of aerobic exercise, the lungs will respire faster to allow more diffusion of oxygen in the blood. Then, this oxygen will be transported to all body by heart pumping and then oxygen enters the cells. Once oxygen is entered, it acts as terminal electron acceptor in a process known as oxidative phosphorylation. This process takes plance in the mitochondria and produces 32 molecules of ATP per reaction.

What would happen if a plant could carry out photosynthesis, but not respiration?
Fofino [41]

Answer:

answer is 1

it would have no food.

Explanation:

Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose stored in the plant for later use. This is why plants are so important to human and other animals' survival. Without photosynthesis, we wouldn't have oxygen or food to stay alive.

Plant cells respire, just as animal cells do. If they stop respiring, they will die. Remember that respiration is not the same as breathing, so take care - plants do not breathe.

describe at least three structures made of dense regular connective tissue and three made of dense irregular connective tissue.
KATRIN_1 [288]

Tendons, ligaments are made up of dense connective tissue with collagen fibers that are more densely packed. The specialized connective tissues of adipose tissue, bone, blood, cartilage and lymph are only a few examples.

The lymph nodes, some forms of fascia, and the submucosa of the intestinal tract are all made of dense, erratic connective tissue. Other examples are the tunica albuginea of the testis and the periosteum and perichondrium of bones. In bodily areas that require support to fend against forces coming from various directions, dense, uneven connective tissue is concentrated in high amounts.

Tissue that provides structure, support, and protection to other human tissues and organs. Connective tissue also stores fat, transports nutrients and other things between tissues and organs, and repairs damaged tissue. A gel-like substance, fibers, and cells make up connective tissue.
