Answer:
Cytokinesis in plant cells involves the formation of the insertion of a new cell wall that separates daughter nuclei after mitosis
Cytokinesis involves the formation of the insertion of a new cell wall that separates daughter nuclei and produce two new daughter cell.
What is cytokinesis ?It is the final stage in the cell cycle, when a new daughter cells is formed from parent cell through the splitting of the cytoplasm and the separation of the two identical cells.
In Stage 1 cleavage furrow is seen where the actin filaments will begin to tighten around the cells, spindle formation occur, t the chromosomes are divided evenly between the two nuclei. The spindle possesses small structures called astral microtubules guide the alignment of the actin filaments along the future cleavage furrow.
In Stage 2 the gathering of the actin filaments occur where some protein called myosin facilitates the pulling of the actin filaments, and formation of contractile ring begins.
In Stage 3 the myosin a motor protein with the help of ATP, it is able to contract the contractile ring, deepening the cleavage furrow, causing the cell to narrow in the middle as two daughter cells form.
In Stage 4 the actual breaking of the cell membrane and the membrane quickly refuses at the broken point and two independent and identical daughter cells are produced.

What do people with Glycogen Disorder Disorder need to do in order to maintain a normal blood glucose?
the muscles and organs need a certain level of glucose in the blood to work properly. When the body is missing an enzyme or has a flawed enzyme and is not able to use glycogen the right way, it leads to a condition called glycogen storage disease (GSD). Many different enzymes are used by the body to process glycogen.
All organisms interact with and depend upon each other and their environment to satisfy their basic needs. Relationships between organisms include predation, competition, and symbiosis. Consider the food web. Select ALL of the relationships that exhibit competition for resources.

Explanation:
American apple cells contain an enzyme that turns the tissues brown when an apple is peeled and left for a time. Boiled apple does not go brown. Explain why the boiled apple behaves differently.
Answer:
I think I got it from recipetips.com
When cooking apples it is not as much of a concern because once they are cooked, the browning will stop. When fresh apples are peeled or cut open, the apple's cells are exposed and react with the oxygen in the air. The reaction that occurs, which is called oxidation, is what turns the apple brown.
Explanation:
Enzymes are proteins. As such they are very specific. When the apple is boiled, the enzyme becomes denatured and as such doesn't turn the apple brown.

How is cross pollination carried out in nature?
A, B, or C?
OPTION B is the correct answer
Cross-pollination is carried out by bees and other pollinators, which is present in option B, as cross-pollination is a process in which pollen from the male reproductive organs of a plant (such as the stamen) is transferred to the female reproductive organs.
Cross-pollination is facilitated by various agents, including insects, birds, wind, and even water. These agents inadvertently carry pollen from one plant to another as they move between flowers or plants. Insect pollinators, such as bees, butterflies, and beetles, are the most common and efficient carriers of pollen in cross-pollination. They visit flowers to obtain nectar or pollen as a food source, and in the process, pollen grains get attached to their bodies and are transported to other flowers.

which process does not occur within a mitochondrion in a eukaryotic cell?
The process that does not occur within the mitochondria of a eukaryotic cell is glycolysis. I can conclude this because I believe you are referring to the options for this question which are:
A) Krebs cycle
B) Glycolysis
C) ATP synthesis
D) Electron transport chain
Glycolysis is a process in which glucose in the cytoplasm of a cell is broken down to produce energy in the form of ATP. The word glycolysis means "glucose splitting". It is one of the stages of cellular respiration. In fact, it is what begins this process.
Glycolysis is an anaerobic process meaning it does not need the presence of oxygen to function properly. Although this is a very important process and does participate in the creation of ATP, it does not occur in the mitochondria, but rather in the cytoplasm of a cell.

using energy to move waste materials out of a cell
Active transport is a type of transport that requires energy to move substances across a membrane. It occurs against a concentration gradient.
The use of energy to move waste materials out of a cell is an EXAMPLE of transport active.Active transport occurs against a concentration gradient, whereas passive transport (i.e., diffusion) occurs in favor of a concentration gradient.Active transport can be mediated by membrane proteins that move substances from an area of high concentration to an area of low concentration.This movement (active transport ) usually requires the energy provided by the hydrolysis of ATP.Water molecules move across cellular membranes through membrane protein channels called aquaporins that act in favor of a concentration gradient (passive transport).
