<u>The cell lacks a nucleus.</u> We know this because prokaryotes are single celled organisms that lack a membrane bound nucleus or membrane bound organelles. So, looking under the microscope, you'd notice that the cell has no distinct nucleus, which immediately helps us find the answer we're looking for.

Which term best describes the systems in an animal's body?
umka21 [38]

Answer:

B. interconnected

Explanation:

All the systems in our bodies (humans are indeed animals) are connected with each other to create a functional being. The blood flows throughout the body, providing nutrients; the bones support the structure and protect the heart and lungs. They work together.

Why not A: The systems are all completely necessary. There's nothing extraneous in our bodies, because extraneous stuff takes up energy, and our biology is incredibly economical.

Why not B: They're not interchangeable. How would you like your bones to turn to blood? Uh-huh.

Why not D: They interact with each other consistently, so they're not separate or segregated.

Describe the main difference between primary and secondary succession.
frosja888 [35]

Answer:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lack soil.

Secondary succession is one of the two types of ecological succession of a plant's life. It is the process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.

Explanation:

Primary succession takes time for completion around 1000 years, whereas secondary succession area takes 200 years for completion. In primary succession, there is a lack of soil and humus for the sustaining of life whereas, in secondary succession, soil and humus are present with some organisms.

A Secondary succession can take a few hundred years.
