Answer:
B) sympathetic and parasympathetic
Explanation:
e autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates smooth muscle and glands. Thus, it directly affects the function of internal organs and regulates functions such as the heart rate, digestion, respiratory rate, urination etc. This nervous system control is unconscious.
The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.
During glycolysis, the source of the chemical energy that is captured in ATP:
B. the chemical bonds in glucose
Explanation:
- Glycolysis is also known as Embden-meyerhof pathway.
- It is an oxidative process in which one mole of glucose is partially oxidized into two moles of pyruvate.
- Glycolysis occurs in the cytosol of the cell in both aerobic and anaerobic conditions.
- The breakdown of six-carbon glucose into two molecules the three-carbon pyruvate occurs in ten steps.
- The first five steps of this pathway constitute the preparatory phase.This phase consumes energy during the phosphorylation of glucose.
- The preparatory phase produces two molecules of glyceraldehyde 3-phosphate (G3P).
- The two molecules of G3P are then converted to pyruvate in the next five steps that constitute the payoff phase.
- The energy gain of glycolysis comes in this payoff phase.
- The oxidation of G3P yields a high energy molegule 1,3 -bisphosphoglycerate .
- The high energy phosphate on carbon 1 of this molecule is donated to ADP and ATP is produced.
- This synthesis of ATP is called substrate level phosphorylation because ADP phosphorylation is coupled with exergonic breakdown of a high-energy bond.
Answer:
The type of pollution demonstrated is sediment pollution.
Explanation:
- Sediment pollution is the deposition of waste products in rivers, lakes and streams by the means of soil erosion.
- So in the abandoned construction site, sediment pollution is the major issue that causes the environment's wind and water to pollute heavily.
- The waste is swept and carried to different places that pollutes the environment badly due to the exposed construction site.
Answer:
The correct answer will be option-A
Explanation:
In the pedigree analysis, the description of a trait help shows the relation of a trait linked to a gene.
The pedigree analysis is usually used to determine the heredity of a disease in a family which has been described in the question also as
1. The trait is rare and present in both sexes- this shows that it is independent of sex chromosomes and since is rare is recessive.
2. A consanguineous mating- mating between close relative which result in autosomal recessive trait as the genes for the trait must be present on both the parents which happen only when they are closely related.
Thus, option-A is the correct answer.
