Will geographical isolation be a major factor in the speciation of an organism that reproduces asexually?Why or why not?

Biology

Oliga [24]3 years ago
8 0

Geographical isolation would have more of an impact on speciation if it was an organism that reproduced sexually. If a positive mutation were to occur in an asexually reproducing organism that allowed it to survive better, evolution would be very sudden. There are many factors that can impact whether an organism is more fit and I do believe geographical differences can influence this. If the climate of an area suddenly drops but one organism can survive, they will pass their genes on and the rest will not.

75% of the children will have the probability of being tasters. 25% will have the probability of being non- tasters.

Answer b)

There will be a 75% chance that their first child or their fourth child will be a taster.

The chances for every child will be the same because alleles assort independently during the time of gamete formation. Hence, the probability remains the same every time.

Answer c)

There will be a 25% chance for the first three offsprings to be non-tasters. 75% chances will be of them being tasters.

This is because the alleles assort independently each time during gamete formation. Hence, the chances will be the same every time.

Dafna1 [17]

Answer:

Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.

Answer:

The correct answer is - disrupting microtubule assembly and proper formation of the mitotic spindle and the kinetochore.

Explanation:

Vinblastine is known for treating cancer cells by sending them to apoptosis. It interferes with the synthesis of microtubules. It binds to the microtubular proteins of the mitotic spindle that causes disrupting microtubule assembly.

It also prevents from proper formation of the mitotic spindle and the kinetochore which is essential to separating chromosomes during anaphase. They arrest mitosis and cause cell death.
