The given statement is False.
Africa was not covered with glaciers during the Pleistocene ice age. Africa was divided into different parts and some part of Africa was was greener and full of different kinds of species.
The tropical Africa had 5 degree less than the temperature of the Africa right now. There were different plant and animals species present at that time.
Answer:
A major change to the Linnaean system was the addition of a new taxon called the domain.
Explanation:
The survival or neuronal development of human embryonic or human induced pluripotent stem cells is not improved by feeding them more than five days per week.
<h3>Why does feeding not increase neuronal differentiation or cell survival?</h3>
An induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) can differentiate into any form of specialized human cell, ESC/iPSC-derived cell types have a lot of potential for use in regenerative medicine.
Neuroscience research can benefit from neural culture of human pluripotent stem cells. However, it is unknown what the ideal feeding schedule for these in vitro systems should be. Human embryonic and induced pluripotent stem cells were cultivated with medium exchange schedules of five, six, or seven days per week during two months of differentiation. We assessed the survival and neural differentiation characteristics of these cells. Through this period of culture, neither human pluripotent cell type showed any appreciable alterations in cell counts or indicators of brain development. We come to the conclusion that feeding this culture system more than five days a week is unlikely to be advantageous.

Answer:
There is 1/6 of the probability that at least one of the children is albino.
Explanation:
Due to technical problems, you will find the complete answer and explanation in the attached files.
Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of exposure of the cell to DNA damaging agents.
Cross over, or recombination, is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
