The substance that helps keep the integrity of the bacterial cell wall intact is known as the peptidoglycan. Others also refer to is it as murein or mucopeptide. The bacterial cell wall is necessary for survival because of the high internal pressure present inside of bacteria. Under normal conditions, if the cell wall is removed the bacterial cell will burst.

The peptidoglycan is a layer that can be used to distinguish gram positive bacteria from gram negative ones. G(+) bacteria have a thick layer of this while G(-) have a thinner ones.

Answer:

In the presence of arsenate glycolysis produces fewer ATP and NADH molecules per glucose molecule.

Explanation:

it is supposed to be 2 molecules of 3-phosphoglecerate with each producing 2 ATP making a total of 4 ATP gain but since it is just one and arsenate, only 2 ATP will be generated instead of four, thus ATP yield is reduced.

aliya0001 [1]
Production of sperms is referred as spermatogenesis and production of ovum or egg is called oogenesis. Spermatogenesis and oogenesis are similar in a way in humans as bth these processes produce large numbers of sperms and eggs. Spermatogenesis is a continuous process where large numbers of sperms are produced at once and uses less energy. Ovulation is a process where only one egg or ovum matures at a time requires more energy. Not all the egg cells mature in females.

irina1246 [14]

Answer:

During the development of the fetus, the mechanism by which the mammalian skeletal system gives rise to tissues of the bone is termed as endochondral ossification. Endochondral ossification also plays an essential role at the time of the development of the long bones length, rudimentary generation of the long bones, and healing of bone fractures naturally.  

The following are the steps in the process of endochondral ossification:  

f. The development of the cartilage model.  

b. The calcification of cartilage takes place and the formation of bone collar occurs.  

a. In the diaphysis, the formation of the ossification center takes place.  

c. In the epiphysis, the formation of ossification centers takes place.  

d. Replacement of cartilage takes place by the bone.  

e. Ossification of epiphyseal plates takes place.
