Weather is the area's day-to-day conditions and climate is the area's average conditions. a natural phenomenon that maintains Earth's temperature range.
I would believe the correct responses would be option 1,2,4.
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.
B cells engulfs bacteria or toxin and then digests it. Then , it represents the antigen on its surface. The b proliferates into memory cells and plasma cells(they act of the foreign substance). Eventually a helper t cell comes on it's way and triggers more cells.
The presence of inorganic molecules is the meteorite condition in space similar to what was likely present in Earth's early atmosphere.
The earth initial atmosphere in its early form was too reducing and it was made up entirely of gases such as carbon monoxide, ammonia, methane, nitrogen and other gases.
This atmosphere did not have free oxygen, since it was the result of the mixture of metals, hydrogen and other chemical elements.
The high temperatures, ultraviolet rays and electrical discharges in the early atmosphere would have caused chemical reactions of the elements to form primitive organic molecules.
Meteorites are fragments of solid matter that contain a record of the chemical substances that existed in the early Solar System.
The most predominant gases still found in the space are hydrogen and helium.
Therefore, we can conclude that hydrogen and the presence of inorganic molecules are the initial elements that make up the Earth's early atmosphere and that they are conditions that are present in the space and so in the formation of meteorites.
