Answer:
Greenhouse gases absorb radiation from the EARTH and reradiate back toward the EARTHwhich help to maintain a normal temperature range in the Earth.
Explanation:
Greenhouse gases are gases that are capable to of absorbing infrared radiations that are emitted from the Earth's surface and reradiating back to the Earth which contributed to the greenhouse effects. Examples of greenhouse gases are carbondioxide, methane and water vapour. Others are ozones, flourinated gases, nitrous oxides e.t.c.
The green house gases has lead to climate changes in the Earth by trapping heat, the contribute to respiratory diseases by smog and air pollution. Greenhouse gases concentrations are high during warm seasons and low during cold seasons.
The question is; would a drug that binds irreversibly to these receptors be an effective contraceptive in mammals?, the answer is;Yes; because if the receptors are blocked the sperms will not be able to penetrate the zonal pellucida of the egg. Contraceptives prevents pregnancy by interfering with the normal process of ovulation, fertilization, and implantation.
Answer:
There are six of them, based on the common compound that they are synthesized
Explanation:
The family of L- glutamate come from the cetoglutarate compound from the Kreps cycle. The family of L-serine, come from 3 - phosphoglicerate compound from the glucolisis. The L - aspartate family, that come from oxaloacetate compound, from the Krebs cylce. The piruvate family that come from the piruvate, from the glucolisis. The aromatic aminoacids, that come from eritrose - 4 - phosphate, from the pentose cycle. And the L histidine family, that come from the ATP.
It modifies, packages,and sorts proteins that will be secreted into the cell. So synthesis of proteins.
