The process of <u><em>meiosis </em></u>increases genetic variability as it produces gametes for sexual reproduction
Explanation:
More complex organisms, including humans, produce specialized sex cells (gametes) that carry half of the genetic information, then combine these to form new organisms. The process that produces gametes is called meiosis. During meiosis, homologous chromosomes (1 from each parent) pair along their lengths.
The correct answer is letter B, burning wood. This is not a renewable resource of energy as its by-product involves the release of greenhouse gases that can still be harmful to the atmosphere or to the environment in general. All the other choices are good sources of renewable power because they harness the power of naturally occurring materials found in their space.
Answer:d) contracting her pupils and increasing secretion of stress hormones.
Explanation:
Peripheral nervous system consists of 3 major neuronal levels: vegetative (reticular formation and brain stem), limbic system and neocortical level. The RAS is the link between the brain and the spinal cord.
Brain stem consists of pons, medulla oblongata and mesencephalon. Brain stem is responsible for involuntary functions such as heart beat, respiration and vasomotor activity. Limbic system represents the emotional control center. It consists of thalamus, hypothalamus and pituitary gland and maintains homeostasis. Neocortical part processes sensory information and regulates emotional responses.
Autonomic nervous system (ANS) regulates visceral activities and organs (circulation, digestion, respiration and temperature). ANS has two divisions: sympathetic and parasympathetic nervous system.Parasympathetic nervous system regulates homeostasis via the release of acetylcholine (Ach). Parasympathetic nervous system is responsible for energy conservation and relaxation.
There are three stages in the stress response: immediate effects of stress, intermediate effects of stress and prolonged effects of stress.
Answer:
It will eventually become unsustainable because of factors like food, water, space, etc.
DNA is necessary for the production of proteins as well as the regulation, metabolism, and reproduction of the cell.
Proteins help repair and build your body's tissues, coordinate bodily functions, and allow metabolic reactions to take place.
Structural, storage, hormonal, enzyme, etc.
Enzymes speed up the rate of a chemical reaction to help support life.
Lipases, amylase, lactase, deoxyribonuclease, etc.
