When we run, we sweat, which means we're getting hotter and hotter and our bodies need to cool down, which they do through transpiration (sweating). If we need to cool down, we need to release the heat that is in our bodies.

To run, we also need to move our muscles, which requires a specific type of energy, called mechanical or kinetic energy, which is the "energy of movement". In our bodies, we don't store that type of energy though, so we have to convert chemical energy to mechanical energy.

Answers:

⭕Heat energy is released from the body to the surroundings.

⭕Chemical energy is converted to mechanical energy that’s used for muscle movements.

A serious, inflammatory condition in which the colon mucosa protrudes through the colon wall is called __________.

myrzilka [38]

A serious, inflammatory condition in which the colon mucosa protrudes through the colon wall is called diverticulitis. Diverticulitis is a related digestive condition that affects the colon. This condition occurs when naturally weak part of the colon tears which result in inflammation or infection. Symptoms of diverticulitis include severe abdominal pain, fever, nausea and constipation.

Involuntary is which type cardiac, smooth, or skeletal?

grin007 [14]

Answer:

Smooth and cardiac

Explanation:

Smooth and cardiac muscles are both involuntary.

This means we do not consciously control them. Smooth muscles are found, for example, in the esophagus, and small intestine. The cardiac muscles are found in the heart.

The skeletal muscles are those that we control consciously, such as the muscles for moving our arms and legs.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.
