Earth would basically look like the Moon; minus the craters, of course. This is because with no atmosphere to hold all of the Oxygen near the surface, all life would die off fairly quickly.
Answer is option A.
A protein deficiency causes such diverse symptoms because immune, nervous, and muscle system cells require proteins for structure and regulation.
Proteins are the building blocks of bones, muscles, cartilage, skin, and blood. They also help in transporting oxygen, helps in blood clotting during injuries etc.
Answer:
The correct option is <u>B. Lipids</u>
Explanation:
Lipids can be described as molecules which dissolve in non-polar solvents and cannot dissolve in water. The biological function of a lipid molecule is to store energy as well as to structure the shape of cell membranes. Lipids are also used in a cell for signalling.
Lipids are made up of carbon, hydrogen and oxygen. Some lipids might have phosphorus in them like the phospholipids which make up the cell membrane.
<u>ANSWER:</u>
The correct order is- Zygote, Blastula, Gastrula, Fetus.
<u>EXPLANATION:</u>
- The embryo develops from the zygote which is formed when the gametes fuse in the process of "fertilization".
- The zygote undergoes cell division to form blastula which is a "ball of cells".
- Gastrula leads to the rearrangement of cells of the blastula into three layers that differentiate into different systems of organ.
- The last stage is the fetus which then develops into a baby.

Explanation:
Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
