Answer:
Light energy from the sun.
Explanation:
Algae, plants and some bacteria such as cyanobacteria uses light energy from the sun, carbon dioxide and water to make organic molecules (sugars) to produce energy for growth. The by-product of this process in plants is oxygen and water vapour, released using the stomata (tiny openings in leaves).
Yeast to get glucose,
the cells must use active transport to move glucose up its concentration
gradient. Yeast cells take up glucose to use as their main source of energy.
Typically, glucose concentrations outside yeast cells are lower than glucose concentrations
inside the cells.
Answer:
The correct answer is: c. It allows animals to respond instinctively to oncoming threats.
Explanation:
- Animals always remain aware of all the sensations that take place in its environment.
- This is because when awake, all the sense organs of the organism remain active. But it is possible that some of the organs are more active than the other.
- Under normal condition, animals sense all the events happening in the surrounding environment but decide and respond to those which they think to be necessary for them.
- But the adaptation of the characteristics of conscious awareness of the surroundings is of particular advantage under the conditions of threat.
- Under the conditions of threat, animals do not get the time to choose and decide whether to respond or not. They always have to give a response instinctively in order to evade the threat.
- This instinctive reaction of what exactly is required to be done in case of a threat is acquired due to the adaptation of the capability to remain aware of the ongoing sensations.
