Which summary best explains the mechanisms that control the cell cycle in multicellularorganisms?
The type of DNA in each cell controls the rate of the cell cycle and the specific type of cells
formed
The size of the cell determines the number of cells that will be produced from each cycle.
Internal and external signals regulate the progression of the cell cycle at various critical
checkpoints
Hormones signal the start of the cell cycle, and DNA determines how the cell differentiates.

Answers

Answer 1
Answer:

Answer:

The correct answer is internal and external signals regulate the progression of the cell cycle at various critical check points.

Explanation:

The cyclic event that helps to prepare the cell for division is termed as cell cycle.Cell cycle are regulated by various internal and external factors which regulates the passage of cell through various critical check point.

 For example Maturation promoting factor helps in the progression of frog egg oocytes cells from G2 to M phase.

    G1 cyclin CDK helps in the passage of cell from G1 to S phase.

Discuss two ways that all cells are alike?

Answers

Well,

First, all cells must have DNA in order to function.  Without DNA a cell could not possible perform basic life functions, such as biosynthesis, absorption, and reproduction, among the innumerable others.

Second, all cells have ribosomes, as proteins are very significant and vital to every cell.  Ribosomes are primarily responsible with protein synthesis.  Even in prokaryotic cells, ribosomes are present.

2. What is the main role of binary fission in prokaryotic cells? (1 point)to produce antibiotic-resistant genes
to transfer genetic materials from one cell to another
to fuse two cells together
to produce identical daughter cells

Answers

Answer:

To produce 2 identical daughter cells!

Explanation:

Binary Fission is a type of asexual reproduction in prokaryotic cells. Binary fission is done to transfer the DNA into the identical daughter cells. Binary means two and Fission means breakdown, so binary fission means breakdown into 2 identical daughter cells. The organism that reproduce this way are

  • Amoeba
  • Black-worms
  • Hydras
