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.

Which statement is false about fungi?
alekssr [168]

Answer:

C) Most fungi get their nutrients by ingesting small pieces of other living organisms.

Explanation:

Most fungi are saprotroph, it is, they obtain  nutrients by decomposing  non-living organic matter -i.e.  dead plant or animal matter-  and absorbing soluble organic compounds; carbohydrates are the preferred carbon source.

A smaller percentage of fungal species are parasites, and obtain nutrients from living hosts (other living organisms).

A mom, heterozygous for type B blood, has a baby with type AB blood, what possible blood types could the baby's father have?
EastWind [94]

Answer:

A

AB

Explanation:

This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).

According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.

The by-products of cellular respiration include A) energy and oxygen. B) glucose and oxygen. C) carbon dioxide and water. D) glu
Paraphin [41]
The answer to this question would be: <span> C) carbon dioxide and water

In cellular respiration, the glucose will react with oxygen, resulting in ATP, carbon dioxide and water.  Adenosine triphosphate or ATP is the main product of this reaction since it can be used to produce energy. So, water and carbon dioxide would be the by-product.</span>
