Answer:

Cytokinesis is the process of the cell cycle which divides the cytoplasm of the parent cell into two cells.

The process of cytokinesis involves the membrane of the cell, so the process differs in plant and animals cell as the plant cell exhibits two layers that are the cell wall surrounding the plasma membrane while animal cell lacks the cell wall. the main difference in both the process is:

1. Plant cell division-occurs by cell plate formation while animal cell division- occurs by full cleavage.

2. In-Plant cell- no cytoskeleton is involved while in animal cell- Cytoskeleton components are actively involved

3. Plant cell division is centripetal while animal cell division is centrifugal

4. Plant cell-wall formation is present while animal cell-Wall formation is absent

The similarities in both the process are that it generates the genetically identical daughter cells. In both cells, cytokinesis after the karyokinesis and is the last stage of the division.

Answer:

Nesting & Foraging behavior

Explanation:

Seabirds are generally tertiary consumers and / or marine predators that, in marine foodwebs, occupy the upper trophic level. They are very well adapted to all marine ecosystems and feed on a variety of prey: from micro-crustaceans to fish and cephalopods.

Generally, seabirds are observed performing a nesting behavior, by laying eggs near the shore, and then are found exhibiting foraging behavior -searching and foraging for prey- in both the coastline and pelagic zone, also known as the open sea.

Seabirds exhibit different foraging behaviors, for example, the surface feeding behavior which involves flying along the surface with their beak in the water. Gulls, albatrosses and petrels are examples of surface feeders.

On the other hand, plunge diving involves preying on fast marine organisms by diving into the water during their flight. Pelicans are example of seabirds who engage in this behavior.

Im not really sure about the water, other than the trees wouldn't be absorbing it so there would be extra? But a huge amount of trees like that produce a lot of oxygen, so there would not be less oxygen in the environment. Hope this helps!

Disruptive selection or diversifying selection describes the changes in population genetics where extreme values for a trait are favored over intermediate values.

So according to this definition, the conclusion can be derived as :

The most common circumference(s) to be after 10 generations of diversifying selection will be greater than 2 cm and less than 2 cm.

What can create biases in people, sometimes that we are unaware of?

ratelena [41]

Answer:

Views, opinions and ideas

Explanation:

Biases are created through that individual's specific Views, opinions, and ideas. As we grow up we develop unique views, opinions, and ideas based on the experiences we go through over the years that generate a strong feeling towards a specific subject/topic. This subconsciously creates biases that strongly influence future decisions when they even remotely connect with the subject/topic in question.
