b. It demonstrated that species arise from other species.
c. It provided a quantifiable mechanism to explain gradual evolutionary change.
d. It was the first time that change in biological organisms was observed.
e. It was not very important to evolutionary biology.
Solution -
The term modern synthesis by coined by Julian Huxley and the goal of this synthesis was to understand and determine how genetics bring evolutionary changes in a population and with this objective it combined the Darwin’s theory of evolution and Mendel’s work on heredity. Later on scientist Dobzhansky under this synthesis found that genetic mutation causes variation through the process of natural selection and hence lead to evolutionary changes in a population even if they are isolated for a long time.
Hence, option C is correct
Answer:
Plant organelle
Explanation:
Only plant cells have central vacuoles used for storing water usually. Animal cells can have vacuoles, but these are never described as central as there can be many and they are not as large as plant vacuoles.
In residential heating, convection is the mechanism by which heat is lost by warm air leaking to the outside when the doors are opened, or cold air leaking into the house through the cracks or openings in walls, windows, or doors. When cold air comes in contact with the heater in a room, it absorbs the heat and rises.
The distinction between protostomes and deuterostomes is based on differences in their embryological development. Protostomes develop their oral end from their first developmental opening, while deuterostomes have their oral end develop from the second opening on the dorsal surface.
