Answer:
Option A. Air pollution can cause water pollution.
Explanation:
Substances can permeate into the water from the air.
The amoxicillin and the ampicillin are known to degrade the cell wall. both of these antibiotics have β- lactam in their structure. The structure of the ampicillin and the amoxicillin is similar having a single difference at the 4th position of benzene ring. The structure of the amoxicillin have an addition OH or hydroxyl group at the 4th position in the benzene ring.
As the structure of ampicillin and amoxicillin is similar, the bacteria having ampicillin resistance can also show amoxicillin resistance.
MODE OF ACTION OF AMOXICILLIN:
The amoxicillin binds with the pencillin binding proteins, present in the bacterial cell wall. The binding of the amoxicillin inhibits the enzyme transpepetidase, which is an important enzyme for the synthesis of the cell wall. it also inhibit murine hydrolases and inhibit the assembling of cell wall.
The amoxicillin effects the cell walls of the bacteria, as the animals cells do not have cell wall, they only have a cell membrane, the increase in the dose would not effect the animal cell.
Answer:
D.
Explanation:
This amount of space in air that can hold water changes depending on the temperature and pressure.
Answer:
The correct answer is embroynic stage
Explanation:
The prenatal development is divided into three stages germinal stage, embryonic stage and fetal stage. The period of two weeks after fertilization is called the germinal stage. In this stage, the zygote divided and gets implanted in the uterine wall.
The embryonic stage starts for two weeks and lasts up to 8 weeks after fertilization. At this stage, the cell mass is called embryo. In the embryonic stage, the basic brain structure, CNS, PNS are developed. All the basic organs and body parts develop in this stage except sex organs. So the right answer is the embryonic stage.
Answer:
Connective tissue that are found in muscle are of 3 types-Endomysium,Perimysium and epimysium.
Explanation:
Endomysium is called as areolar connective tissue that have nerve and capillaries.
It attaches with epimysium and perimysium and form collagen fibers of tendons.
Perimysium is a sheath of connective tissue that transmit lateral contractile movement.
Epimysium is the layer that is formed by irregular connective tissue .
This layer covers the muscle and provide protection from friction against muscle and bone.
This layer contain fascia and other connective tissue.
