Which stage of the cell cycle occurs after mitosis in which the cell creates a cleavage furrow.
Interphase
G2
Anaphase
Cytokinesis
Answer:
Anaphase
Explanation:
After anaphase, a cleavage furrow forms in the equatorial cortex in typical animal mitosis. To divide the two daughter cells, this furrow then progresses inwards.
The sister chromatids differentiate from each other in anaphase and are pulled toward opposite ends of the cell. The "glue" of protein that binds together the sister chromatids is broken down, causing them to separate. Each one now has a chromosome of its own.

Which of the following statements about an energy pyramid is NOT correct?
Group of answer choices
Only about 10% of energy is passed from one trophic level to the next.
Autotrophs are always located at the bottom of the pyramid.
An energy pyramid shows the same flow of energy as a food chain does, it just stacks the trophic levels on top of each other.
Ecosystems have more energy at higher trophic levels than at lower trophic levels.
Answer:
The answer that would NOT be correct is the last one , (Ecosystems that have more energy at higher trophic levels than at lower trophic levels. )
Which of the following best describes the function of the coenzymes NAD and FAD
in eukaryotic cellular respiration?
Answer:
They accept electrons during oxidationreduction
reactions.
In cellular respiration in eukaryotic, reducing power is provided to the electron transport chain by NAD and FAD, so they act as electron acceptors in the process.
What is the function of coenzymes NAD and FAD in eukaryotic cellular respiration?In eukaryotic cellular respiration, they function as the electron transport chain's ultimate electron acceptors.
The cofactors nicotinamide adenine dinucleotide (NAD+) and flavin adenine dinucleotide (FAD+) is important in cellular respiration. They receive "high energy" electrons and convey them to the electron transport chain.
Where they are utilized to manufacture ATP molecules, and is the energy source for all the cellular process in eukaryotic organisms.
Therefore, NAD and FAD is electron acceptor during cellular respiration in eukaryotes.

Smallpox is caused by a virus that infects people causing painful sores. Jenner performed his smallpox vaccine experiment in 1796. Using your knowledge of the immune system and vaccines explain how humans were able to get rid of this disease in the human population by 1980.
Answer:
Vaccines are samples of a specific virus. This sample gets the immune system ready and weary of the virus. Jenner used fluid from a smallpox patient and added it to a wound of another person. The person recieving the vaccination did not get the virus. Of course, vaccination technology has improved greatly. By continuosly vaccinating, the small pox virus had no vessels to infect and eventually, died off.

How a mustard plant can be the correct example of multicellular organization? Justify your answer.
Answer:
he needs to get a glizzy.
Explanation:
because its big
A mustard plant is an example of multicellular organization because it is composed of multiple cells that work together to form tissues, organs, and ultimately, a functioning organism.
A mustard plant, like other multicellular organisms, exhibits a high degree of cellular organization. The plant is made up of specialized cells that have differentiated functions. These cells come together to form tissues, such as the epidermis, cortex, and vascular tissues, which perform specific functions necessary for the plant's growth and survival.
Within these tissues, cells are further organized into organs, such as leaves, stems, and roots. Each organ has a specific structure and function that contributes to the overall functioning of the plant. For example, leaves are responsible for photosynthesis, stems provide support and transport nutrients, and roots anchor the plant and absorb water and minerals from the soil.
The coordination and communication between cells, tissues, and organs allow the mustard plant to carry out essential processes like growth, reproduction, and response to stimuli. Each cell relies on the coordinated actions of neighboring cells to ensure the proper functioning of the plant as a whole.
Furthermore, the multicellular organization of the mustard plant enables it to exhibit complex characteristics and adapt to its environment. It allows for specialized functions, division of labor, and the ability to respond and adapt to changing conditions.
In conclusion, a mustard plant serves as a suitable example of multicellular organization because it demonstrates the hierarchical arrangement of cells into tissues and organs, enabling the plant to function as a complex and coordinated organism.
