How is cytokinesis different
in plants and animals?
Answer:
Animal cells have a cleavage furrow which will pinch the cytoplasm into two nearly equal parts. While plant cells have a cell plate that forms halfway between the divided nuclei.

Explanation:
The plasma membrane: Question 3 options: is the gene-containing control center that directs all cellular activities regulates the entry and exit of cell materials is the site where ribosomes are assembled prior to their migration into the cytoplasm defines the limits of the nucleus
Answer: The plasma membrane (regulates the entry and exit of cell materials).
Explanation:
All living organisms are composed of one or more cells. The cell can be defined as the smallest functional unit of all living organisms. Also called the basic organizational unit of life.
Cells are found to have many features in common. However, a generalized cell does not exist. The precise structure of a cell is closely related to the work it does.
According to the structure of a cell, it has a living material called protoplasm. The protoplasm is enclosed by a membrane known as the PLASMA MEMBRANE.
The PLASMA MEMBRANE is a flexible membrane that is made up of mainly proteins and lipids. It prevents the cell contents from escaping to the exterior. It is also selectively permeable, that is, it controls the materials which are allowed to enter or leave the cell.
Other structures of a cell include:
--> Nucleus: This is the most important cell structure as it houses the genetic information of the cell.
--> The cell wall: this surrounds the plasma membrane but is freely permeable.

What is oxygen?And how it works?
Answer:
Oxygen is a gas that your body needs to work properly. Your cells need oxygen to make energy. Your lungs absorb oxygen from the air you breathe. The oxygen enters your blood from your lungs and travels to your organs and body tissues
Answer: oxygen is like a gas that helps your body work and breathe. For example your lungs need air and etc. Then chemicals from red blood cells pick up the Oxygen and bring it to the body tissues and cells

Explain how symbiotic relationships are similar to and different from predator-prey interactions.
Answer:
Symbiotic relationships are characterized by one organism feeding off of another, but both organisms benefit from the interaction. Predator-prey interactions involve one organism hunting and consuming another organism for sustenance. Both involve one organism feeding on another, but symbiotic relationships also benefit the host.

Scientists study rainforests as systems structured in vertical layers, or strata.
How would a tree falling from the top most layer most immediately affect the surrounding plants in the other lower layers?
Answer: More sunlight less space
Explanation: The fallen tree would leave there less space however there would now be more sunlight due to the tree not covering it up anymore
A tree falling from the top most layer most immediately will provide more sunlight and space to the surrounding plants in the other lower layers in a rainforest.
What is a rainforest ?
Rainforest is a thick forest in tropical parts of the world with tall, mostly evergreen trees and a high amount of rainfall.
The space left by a fallen tree allows more light to reach the forest floor as well as space for other vegetation to take root and flourish.In the later stages the nutrients a tree used to build itself during its lifetime are spread into the soil and make it richer for other plants around it to use.To know more about rainforest here
