Answer:
It is well supported by evidence.
Answer:
c
Explanation:
The very primitive and early microorganisms on the earth's surface were protobionts. Protobionts are cell-like microscopic structures, and they are made up of organic and inorganic molecules present in a lipid bilayer membrane. The layers of the lipid membranes were folded into bilayers and transformed into a bubble shape when placed in water. These membranes were selectively permeable and also observed shrinkage and swelling in osmotic conditions. Protobionts also possess the characteristics of reproduction.

Answer:
Archaebacteria
Explanation:
Carl Woese categorised the bacteria into two domains called the Archaebacteria and the Eubacteria.
The Archaebacteria is the group of bacteria which can survive in the extreme condition as they posses the characteristics of both the prokaryotes and some eukaryotes. The bacteria are known as the extremophiles.
In the given question, the bacteria which lives in the gut of the human uses methane gas and thus are known as the methanobacteria. These bacteria are considered the archaebacteria as they methane for survival.
Thus, Archaebacteria is correct.
Answer:Cell cycle
Explanation:
It's a series of events that take place in a cell leading to duplication of its DNA and division of cytoplasm and organelles to produce two other cells.
The correct answer is Micropyle.
The micropyle can be defined as opening in the ovum that allows the pollen to enter into it for the process of fertilization. In gymnosperm the pollen is drawn into the ovule on a drop of fluid that comes out of the micropyle, called as pollination drop mechanism. Micropyle is present in gymnosperm and absent in pteridophytes.
