The answer is; A
This model hypothesizes how life started during the early conditions of the earth which were hot and filled with greenhouse gases in its atmosphere about 4 billion years ago. It is explained by the theory of spontaneous generation where organic molecules were created from inorganic molecules spurred from energy from lightning. These organic molecules filled the water bodies and chemically arranged themselves, over time, into primordial life.
B. because the rock is formed and it goes younger as it grows the rock is still old on the inner layers but it adds new layers as it goes
Answer:
The correct answer will be option B- cytosol.
Explanation:
Glycolysis is a series of reactions which breaks down the glucose (6C molecule) to pyruvates (3C molecule).
The reaction is the first stage of the aerobic respiration which proceeds in ten steps. The reactions take place in the "cytoplasm of the cell" of all organisms from micro-organisms to plant and animals.
Thus, Option-B is the correct answer.
The flagella of the eukaryotes is composed of the doublet microtubules. The central bundle of these microtubules is known as the anoxeme. In an axoneme, a single pair of the singlet micortubules is surrounded by the nine doublet microtubules. When the plasma membrane of the flagellum is opened to expose the axoneme, and the radial spokes are broken, it will lead to the elongation of the axoneme,
