Question :What are forms of cell regulation
Answer: Regulator Molecules of the Cell Cycle. In addition to the internally controlled checkpoints, there are two groups of intracellular molecules that regulate the cell cycle. These regulatory molecules either promote progress of the cell to the next phase (positive regulation) or halt the cycle (negative regulation).
Remember: Any process that controls the series of events by which a cell goes through the cell cycle. During the cell cycle, a cell makes a copy of its DNA and other contents, and divides in two.
Diffusion is the type of transport that oxygen and carbon dioxide use to cross the cell membrane
The functions of eyes parts are as follows:
Retina: The rays of light focused on the retina by the cornea and lens. The retina produces an image which is sent along the optic nerve of the brain.
Iris: It changes the size of pupil and allows different amount of life to enter the eyes.
Pupil: The light enters to the eyes through it.
Cornea: It forms the outer coating of the eyeball and covers the iris and pupil.
Lens:
Answer:
Bad mutation: deletion/addition mutation
Good mutation: silent mutation
Explanation:
Addition or deletion mutation results in the reading frame of codons to be changed, leading to a extensive missense mutation that will lead to a non-functional protein product to form.
Good mutation are silent mutations that leads to no change to the final product but causes codons to change in sequence. This increases genetic diversity in the gene pool that enables the species to be more resilient to environmental changes.
