Answer:
b. Vernalization
Explanation:
Vernalization is a phenomenon in which plants require low temperature for the flowering. There is either qualitatively or quantitatively dependent on exposure to very low temperature. This process is known as vernalization. Vernalization defines especially to the promotion of flowering by a period of low climate. For example; Vernalisation occurs in biennial plants. Biennials are monocarpic plants which normally flower and may die in the second season. Some common examples of biennials are carrots, Sugarbeet, cabbages, etc.
Explanation:
Wegener used evidence of climate change to support his hypothesis. As a continent moves toward the equator, its climate becomes warmer. As a continent moves toward the poles, its climate becomes colder. But the continent carries with it the fossils and rocks that formed at its previous locations.
Answer:
Ethylene
Explanation:
Ethylene is a hormone required to trigger fruit ripening, and it can be blocked by using synthetic compounds, such as 1-methyl-cyclo-propene (1-MCP).
Answer:
A. both stores mature sex cells.
Answer:
The producers-Sea weed-Perform photosynthesis.
The filter feeders- sponges, chiton-eat floating planktons.
Grazers -Snails,mussels feed on- floating planktons.
Carnivores such as sea stars feeds on snails
Explanation:
- The producers are placed at the bottom level in energy pyramid and are prime factor in the aquatic eco system which provides energy and perform photosynthesis with the help of water,sunlight and chlorophyll.
- The filter feeders are those that feeds upon small particles that are present in the water.
- Grazers are those organisms that feeds on producers like phytoplanktons.
- Carnivores are those organisms that feeds on herbivores.
