Living things come from other living things through either sexual or asexual reproduction.
Iteru [2.4K]

Explanation:

Organisms don’t have to only reproduce sexually or only reproduce asexually - some animals do both!

When conditions are good, such organisms will reproduce asexually because it is easier. For example, starfish (by fragmentation), slime molds, and water fleas/daphnia (by parthenogenesis) all reproduce asexually when there is plenty of food, minimal predators, and not too much crowding of individuals of the same species.

When conditions worsen (less food, too many individuals, etc), they may switch to sexual reproduction in order to add genetic variation to their population and ensure survival through difficult times.

  • These antibiotics can either be of broad-spectrum or the narrow spectrum.
  • The broad-spectrum antibiotics are the ones that are effective against a variety of bacteria, both gram-positive and negative whereas the narrow-spectrum antibiotics are the ones that target only a specific type of bacteria.
  • Since the bacteria can mutate very fast and hence, develop antibiotic resistance, the doctors usually avoid prescribing broad-spectrum antibiotics and only use them when the causal bacteria is completely unknown.
  • Hence, in the given case the provider prescribes separate medications for both types of bacteria.

B. This answer is wrong, at 30°C the enzyme shows a low activity.

C. This answer is correct because at this temperature the enzyme produces the higher amount of bubbles.

D. The activity of the enzyme at 0°C was not tested.
