Answer:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells.
Explanation:
The cell copies its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
Answer:
a) seedless (bryophytes) vs. seed condition (all others)
Explanation:
They produce enclosed gametangia( sexual) and sporangia(asexual), but they do not produce flowers or seeds. Reproduction proceeds through sexual and an asexual phase. They produce spores.
Answer:
The correct option is : c) Glycerophospholipids
Explanation:
The lipid bilayer of the plasma membrane is composed of glycerophospholipids, sphingolipids and sterols.
The sphingolipids are the derivatives of sphingosine. Whereas, <u>the glycerophospholipids are the derivatives of </u><u>phosphatidic acids</u>.
Phosphatidic acid are the phospholipids that give one glycerol molecule, one molecule of phosphoric acid and two fatty acids molecules on hydrolysis.
<u>Therefore, Phosphatidic acid is a precursor of glycerophospholipids.</u>
Answer:
A. in order to release the energy found in food.
Explanation:
Every cell in your body needs oxygen to function. You get the oxygen your cells need from the air you breathe. The air you breathe is made up of 20 percent oxygen. The rest of the air is mostly nitrogen (79%). Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. This is very similar to wood burning in a fire. As the wood burns, it combines with oxygen and releases heat energy and carbon dioxide. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released. But instead of heat energy, much of the energy produced in cellular respiration is stored chemically for the cell to use later. Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs. The opposite takes place in the cells where the blood releases oxygen and picks up carbon dioxide.
The correct answer is letter A, the increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.
This is one of the many chain reactions that agricultural farming brings to the environment, and it will be very common through the years as people have not figured out a safer way to protect crops.
