They lay eggs because they don't have the genetics or things in their body to give birth.
Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.
Answer:
<h2>lactic acid</h2>
Explanation:
Glycolysis is the process of the breakdown of glucose by enzymes, and the energy production in the cell. It occurs in all cell in all organism. Through glycolysis, there is the production of ATP and NADH, which are used in energy requirement. Glycolysis occurs in cytosol, with the help of various enzymes, like hexokinase, phosphofructokinase and PEP etc. When glycolysis produces pyruvic acid faster than it can be used by the mitochondria, the pyruvic acid is converted to lactic acid.
In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile. The haploid condition of the two gametes is essential so that at fertilization during sexual reproduction the integrity of the chromosomal number is maintained throughout generations.
Hope this helps.
