Please help Explain why a lack of gravity might cause muscles to weaken

Biology

Answer:

Lack of gravity causes you to use less work to move your muscles.

Explanation:

If on Earth your arm weighs 3 pounds, the muscle will only have to move 3 pounds of force. For example, if you were to go on the moon, your arm would have the same mass but there would be less gravity pulling it dow. So now your muscles only need to pull 1 pound. Over extended periods, you would be working less, thus not using your muscles to fullest potential and in result you would get weaker.

Because astronauts work in a weightless environment, very little muscle contraction is needed to support their bodies or move around. Without regular use and exercise our muscles weaken and deteriorate. It's a process called atrophy.

Nataliya [291]
Out of the three domains, Archaea, Bacteria and Eukarya, the vital differences may be identified in order to classify the cell. Eukaryotic cells possess membrane-bound organelles; on the other hand, the domains archaea and eukarya contain cells are prokaryotic, so they do not have membrane bound organelles. Moreover, they also possess ester linkages in their cell membranes, which allow them to survive more extreme environments (especially true for archaea). By studying the cell membrane of the cell, distinction can be made.

Check all of the statements that are true regarding keratinized stratified squamous epithelium.
strojnjashka [21]

Answer;

-Keratinized stratified squamous epithelium forms the epidermis of the skin.

-In keratinized stratified squamous epithelial tissue, the cells on the apical (outer) surface are dead.

Explanation;

-Stratified squamous epithelium is a type of tissue found covering and lining parts of the body. Stratified squamous epithelium may be keratinized or nonkeratinized. Non-keratinized surfaces must be kept moist by bodily secretions to prevent them from drying out.

-The cells on the surface of stratified squamous keratinized epithelium are very flat. Not only are they flat, but they are no longer alive. They have no nucleus or organelles. They are filled with a protein called keratin, which is what makes our skin waterproof.

Ilia_Sergeevich [38]

Answer:

Option A,  Ohio River and the Missouri River

Explanation:

The historical evidences clearly indicate that Ohio River did not exist before the last ice advances. Before Ohio and Missouri river, the major glacier drainage of the east-west direction happens in Teays River. When ice of the glaciers blocked the Teaya river valley, then the Ohio was formed.

Like Ohio, Missouri river did also not exist before Pleistocene and during that time the largest drainage in North America take place in the Hudson's Bay
