Does the thirst mechanism always underestimates fluid loss during work in the heat and after work ends?
V125BC [204]
YES.
The thirst mechanism always underestimates fluid loss during work, in the heat and after work ends. Therefore you should take frequent drinks through out the work period. If you drink 250mililitres every 15 minutes, you can replace one litre per hour. if sweat rate is higher you will find it extremely difficult to keep up with fluid needs. During prolonged periods of work in the heat, weight loss exceeds 2 percent therefore the person should rehydrate before returning to work.

Consider this animal cell. The organelles in an animal cell are labeled. Part D are stacked tubular structures. Which organelles
Dima020 [189]

Answer:

The image of the animal cell was not included in the question, the image has been added as an attachment.

The answer is centrioles; found in animal cells but not plant cells

Explanation:

According to the question, the image in the attachment section is an animal cell with labelled organnelles. An animal cell does not possess a Chloroplast, which is unique to only plant cells. Hence, organnelles D cannot be Chloroplast.

Ribosomes are organnelles made up of a complex of RNA and proteins. They are the site of protein synthesis, which occurs in all living cells. Hence, all cells including plant and animal cells contain Ribosome organnelles. Therefore, it is a wrong choice.

Centrioles are cylindrical tube-like structures made up of microtubules arranged in a specific pattern. Centrioles are present only in animal cells and play a major part in cell division, where they organize microtubules that separate chromosomes. As seen in the image, the two centrioles are perpendicular to one another, forming a CENTROSOME. A plant cell does not possess centrioles instead they contain microtubules organizing centres (MTOC).

Mitochondrion are present in both animal and plant cells as energy-generating organnelles but they are not stacked tubular structures as described in the question.

The human stomach is an organ. Describe how the tissues in the stomach enable the stomach to function. ​ ​
Nikitich [7]

Answer:

Connective tissues support the tissues of the mucosa and connect it to the muscularis layer. The blood supply of the submucosa provides nutrients to the wall of the stomach. Nervous tissue in the submucosa monitors the contents of the stomach and controls smooth muscle contraction and secretion of digestive substances.

The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
