4. Takes place in favourable as well as unfavourable conditions

5. Immortality is absent

Example: Plasmodium reproduces through multiple fission

Binary fission happen in favorable condtion where nucleus of (ex : amoeba) divides by mitosis giving two daughter cells and the mother cell disappears while multiple fission can happen in both favorable and unfavorable the nucleus undergoes repeated division to produce a large number of nuclei Each nucleus along with little bit of cytoplasm forms a membrane around it

If the lionfish population keeps rising, what would be the possible effect on the trophic levels of
the ecosystem?

Answers

Answer:

As lionfish populations grow, they put additional stress on coral reefs. For example, lionfish eat herbivores, and herbivores eat algae from coral reefs. Without herbivores, algal growth goes unchecked, which can be detrimental to the health of coral reefs.

Explanation:

The lionfish are eating other consumers, so the native consumer populations are dwindling. This decrease can have a ripple effect. Larger predatory animals may not have enough food to eat because the native species are decreasing.

The tongue is an example of an organ that assists in the process of digestion. which of the following best describes the level of structural organization for organs like the tongue?


A. It is less complex than a tissue


B. It is more complex than an organ system


C. It is less complex than a cell


D. It is more complex than a tissue

Answers

Answer:

C

Explanation:

The level of structural organization for the tongue is that it is more complex than a tissue. So the correct option is D.

What is a tongue?

In most vertebrates, the tongue is a muscular organ on the floor of the mouth that may move in a variety of ways. It is extended and specialised in grabbing insect prey in some animals (like frogs).

While cats and certain other animals use their tongues as tools for grooming and cleaning, some reptiles' tongues serve largely as sensory organs.

The tongue is an essential auxiliary organ in chewing and swallowing, helps mammals create negative pressure in the oral canal to permit sucking, is a key carrier of taste receptors, and helps humans speak.

The mammalian tongue is formed of a complex of striated, intertwined muscles, fat, and glands, all coated in mucosal surfaces. Humans often have their front tongue ends and margins in contact with their teeth, which facilitates communication and swallowing.

Therefore the correct option is D.
