Answer:

Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.

Answer:

The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants. Explanation: hope this helps

From fossil evidence, you know two species shared a common ancestor approximately 50 million years ago. In comparing a known neu

MissTica

Answer:

Option c ( $2\times 10^{-9}$ ) is the correct alternative.

Explanation:

Given:

Common ancestor,

= 50 million years ago

Base differences,

= 92

Now,

The predicted mutation rate will be:

= $\frac{92}{50\times 10^6\times 1000}$

= $\frac{1.84}{10^9}$

= $1.84\times 10^{-9}$

or,

= $2\times 10^{-9}$

Thus the above solution is the right one.

Gel electrophoresis separates dna fragments on the basis of differences in their ______. a:c ratio

KengaRu [80]

The answer is length.

A gel electrophoresis is used for separation of DNA or its fragments on the basis of differences in their length. An electric current is running through the gel with positive pole on the bottom. Because of the difference in the lengths of DNA fragments, some <span>of them </span>will travel more quickly than other. It is expected to see smaller DNA fragments at the bottom of the gel and larger DNA fragments near to the top of the gel.
