The biological species concept proposed by Mayr states that a biological species is a population whose members can interbreed and produce fertile offspring.
<h3>What is the biological species concept?</h3>
The biological species concept is a model used in biology sciences to delimit a species through mating fertile features of the individual that belong to such species.
This concept (biological species concept) was proposed by Ernst Mayr to understand how each species represent a functional unit.
In conclusion, the biological species concept was proposed by Mayr and states that a biological species is a population whose members can interbreed and produce fertile offspring.

Answer:
im gonna have to go with D
Answer:
Option D, Either of the two answer choices could explain
Explanation:
Yeast has different types of enzyme that convert different sugar into different form based on the environment. For example maltase enzyme is necessary to convert maltose sugar into simple sugar in aerobic condition under specific pH and temperature range. While on the other hand glucose can be converted into alcohol in anaerobic conditions.
Thus, the factors which could affect the respiration pathway adopted by yeast depends on
a) Environment condition including presence of air, temperature and pH
b) Type of food available and enzymes
Hence, both option A and B can explain the experiment results.
Thus, option D is correct
Answer:
They are composed of molecules that contain carbon-carbon bonds.
They undergo chemical reactions to use energy they acquire from the environment.
Living things are organisms that displays characteristics of life. These characteristics includes the ability to grow, reproduce, use of energy, excrete out waste, respond to the environment and have organised structure.
The entry of the sperm nucleus is facilitated by C) acrosome reaction. The acrosome is the head-like structure at the front of the sperm cell. This contains digestive enzymes that break down the outer membrane of the egg cell, allowing the nucleus of the sperm cell to enter and fuse with the nucleus of the egg cell.
