Answer:

Gills are evaginations of the body surface. Some open directly to the environment; others, as in fishes, are enclosed in a cavity. In contrast, lungs represent invaginations of the body surface. Many invertebrates use gills as a major means of gas exchange; a few, such as the pulmonate land snail, use lungs.

Answer:

Basically, gills filter the water around the animal and take in the small amount of oxegen mixed in the water. Lungs take in all of the air and almost half of it is oxgen and they can't go underwater for long. But since lungs are more efficient, animals with lungs can grow bigger than animals with gills

Alex73 [517]

Answer:

Considering that the allele for brown pigment is CB and that for white pigment is CW, the genotype for the brown bird is CB CB and that for the white bird is CW CW.

Crossing CB CB × CW CW,

100% CB CW - tan-coloured birds

Explanation:

The bone marrow is the soft tissue inside bones that helps form blood cells. It is made up of a liquid part and a more solid part.  And it is found in the hollow part of most bones. The bone marrow is

The biopsy and bone marrow aspiration are usually done at the same time. Together, these two procedures may be called a bone marrow study.

Marrow aspiration is the removal of a small amount of this tissue in liquid form for testing. Bone marrow biopsy and bone marrow aspiration are procedures that allow samples of bone marrow (the spongy tissue inside some of the longer bones) to be removed and tested.  In a bone marrow biopsy, the doctor uses a needle to remove a sample of the solid part. In a bone marrow aspiration, a needle is used to remove a sample of the liquid part.

<u>Bone marrow aspiration and biopsy may indicate whether the bone marrow is healthy and producing normal amounts of blood cells</u>. Doctors use these procedures to diagnose and monitor blood and marrow diseases, such as some cancers and fevers of unknown origin.  <u>After the procedure, it is important to control the wound so that it does not become infected, and to monitor vital signs.</u>
