Answer:
haploid (n) or triploid (3n)
Explanation:
If none of the chromosomes separate during meiosis, the resulting gametes will either lack chromosome or have diploid number (2n) of chromosome instead of a haploid number.
If an egg without chromosome (o) fertilizes a normal sperm (n), the resulting zygote will have haploid number (n) of chromosome.
If an egg with diploid number of chromosome (2n) fertilizes a normal sperm (n), the resulting zygote will be a triploid with 3n number of chromosome.
A. Science cannot answer philosophical questions. Philosophical questions could be described as rheoretical questions, such as "what is the purpose of life?" These questions' answers can very from person to person. Science answers questions such as "what is the boiling point of water?", or "what is the chemical structure of water? These are both questions that have the same answer, no matter who is asking them. You just have to have the ability to accurately measure and observe the things involved, or in this case, the temperature of the water when it starts to boil or whe different atoms in the water.
Let's examine the other questions.
B. science can answer only mathematical questions. As you saw in the explanation above, science can also answer other questions, as long as they have a definite answer that we can accurately measure.
C.Science can answer any questions. Again, we have already saw that science cannot answer philosophical questions, so science cannot answer any question.
D. Science can answer any difficult questions. As with the example of the chemical stucture of water, we can answer difficult questions with science. This may seem simple to you, but it would be very difficult if it was not already known!

1. Regulation of glucose blood levels is an example of negative feedback mechanism.
Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.
Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.
• Pancreatic cells-sensors
• Insulin-control system
• Body cells- effector cells
2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.
This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.
3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.
Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.
Answer:
A
Explanation:
Logically, the cell would have two nuclei because karyokinesis (the division of the nucleus) occurs before cytokinesis (division of the cytoplasm).
