Write a five sentence paragrgh explaining the cell cycle
Nady [450]

Answer:

The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.

New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.

Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.

The two main parts of the cell cycle are mitosis and interphase.

Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”

The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.

Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.

Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.

How is energy lost from from an ecosystem?
Serhud [2]

Answer:

Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.

PLS HELP ME USE THESE TERMS FOR THE EVIDENCE!!
Scrat [10]

Answer:

Evidence: During photosynthesis, plant cells use sunlight to synthesize food. This is followed by cellular respiration, which converts the products of photosynthesis into chemical energy. Though animal cells do not use photosynthesis, they still perform cellular respiration in virtually the same way. Plant cells are the producers of glucose, and animal cells are the producers of oxygen, these are both reactants in the process of cellular respiration. The products of cellular respiration include carbon dioxide and water. The plant cells are consumers of animal cells waste products.

Explanation:

Claim: Both plants and animals perform cellular respiration
