Answer:
At its last stage
Explanation:
Mitosis is complete when it has finished its last stage, which is known as telophase. During telophase, the chromosomes or the genetic material are already separated on opposite sides of the large cell. When this happens, the chromosomes begin to be enveloped in their own separate nuclei.
Answer: Feedback mechanism
Explanation:
Feedback mechanism is the body's way of maintaining physiologic processes in the body. These physiologic processes include maintaining homeostasis, production of energy, hormones as well as enzymes required for chemical reactions.
There are 2 types of feedback mechanism:
- Positive feedback: The stimulus (message) sent to the brain, produces prolonged increased production or increased activity in the body.
- Negative feedback: In negative feedback, the stimulus causes production, secretion or activity till a set point where the body knows it has taken enough. This causes a self termination of the process.
In the increased muscle activity, the increase in activity in turn causes a decrease in energy (ATP) and serves as the stimulus leading to the release of enzymes which in turn lead to increased absorption of glucose which will be used by the body to produce more ATP needed for the muscular activity. At the end of the muscular activity, the body recognizes that it doesn't need an increased absorption of glucose to support increased activity anymore and glucose absorption normalizes.
Answer:
1. There are three type of population distribution namely uniform, random and clumped.
a) Uniform distribution also know as a rectangular dispersal or distribution that has constant probability. This is also a family of symmetric probability distributions.
b) Random distribution takes place where individuals are spaced at unpredictable spaces or distances from each other.
c) Clumped distribution is when individuals in a population are clustered together, making some patches with other organism or individuals.
