He grouped the types of creatures according to their similarities: animals with blood and animals without blood, animals that live on water and animals that live on land.
Answer:
White-tailed deer fill the niche, or role, in ecosystems of both herbivore and prey. They are affected by, and themselves affect, their ecosystem. In forests, they have been described as a “keystone species” because their feeding activity can directly and indirectly affect many plants and animals.
Explanation:
The salt solution is meant to lower the ice melting point hence keep most of the water from turning into ice even at zero degrees temperatures. The salts are dissolved in the water to form a salty solution that percolates the ground and reach plant roots. Because the salty water is hypertonic (more concentrated) to the cell cytoplasm of the plant roots, water is drawn from the plant by osmosis. This is the reversal of normal plant root absorption of water from the soil. This causes the plant root to wither and subsequently the whole plant to die. Remember in osmosis, water moves from the less concentrated solution to the more concentrated solution through a semipermeable membrane.

The bias conditions that must be present for the normal operation of a
transistor amplifier will be those in which the emitter-base junction is
forward biased, and the collector-base junction will be reverse biased.

1 - A ground level plant develops curling tendrils that wrap around other objects so it can "climb".
This is a species changing over time as it was originally a ground level plant but began to climb higher.
2 - Over many generations.
This is because diversity takes time and has to be integrated through generations; for instance, marriage. In a family, it becomes more diverse after the next generation as each generation is likely to marry someone of another ethnicity and allow the family tree to become more diverse.
3 - Mutate or Survive
It depends on what it means by mutate - develop a mutation to make it adaptable? If that's the case, then mutations within the DNA would be a result of adaptation and increase survival. Otherwise, survive is the obvious answer as adaption allows for species to move around and live longer.
Hope this helps!
