Biogeographic isolation refers to the separation of the members of the similar species, or a group of organisms, which breed and generate offspring that can further give rise to young ones.
The separation can be achieved by the geographical forces like oceans, rivers, and mountains, and by the biological forces, like hunting times, and spring or fall mating.
virus being a none living organism outside a living cell makes it none living. to me, at this age, to make a living virus to go back to not living, is to subject the infected cells under high treatment or damage the cell totally.
bacteria can always be cured with antibiotics
Answer:
The larva gets dark pigment.
Explanation:
If scientists purposely injected an excess concentration of these proteins in the larva, the larva gets deep dark colour because this protein is responsible for the pigment colour in the larva of Drosophila. By increasing the protein concentration the pigment will also have a very dark colour. So we can conclude from this that increasing the amount of protein causes increase in the pigment colour.
Answer:

Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.
