Answer:
are there any options to choose from?
The answer is mitosis.
Mitosis and meiosis are both 2 different kinds of cell division process. In mitosis, a parent cell will divide and produce 2 daughter cells that are genetically identical to both the other daughter cell and the parent cell. Since this process produces identical cells, it is mostly used in growth, tissue repair etc.
On the other hand, meiosis is the cell division process where a parent cell produces 2 daughter cells, and the two daughter cells produces 4 more daughter cells, and these daughter cells are genetically different to each other, they only have half of the chromosomes than its parent cell. Meiosis is used in producing gametes, so that when 2 gamete fuse together, in fertilization, the zygote can retain the correct amount of chromosome.
Therefore, since skin is not used in reproduction and its chromosomes should be the same as the original skin cell, mitosis is the answer.
Answer:
Nerve impulse
Explanation:
A nerve impulse is transmitted through the synaptic cleft by acetylcholine. When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the presynaptic membrane releasing the acetylcholine. The transmitter substance makes the membrane permeable. An action potential is then formed along the neuron.
Answer: B. The number of bacterial colonies that grew
Explanation: The number of bacterial colonies that grew depend on the temperature, nutrients, and time of day.
Answer:At heart, all life on Earth uses a membrane that separates the organism from its environment. ... In this regard, water is essential simply because it's a liquid at Earth-like temperatures. Because it flows, water provides an efficient way to transfer substances from a cell to the cell's environment.
