The reason why Koala bears are restricted to live in a
certain habitat is because they can only eat a certain type of eucalyptus leaf.
These bears are indigenous to Australia. They are nocturnal and live in tropical
where temperate eucalyptus forest can be found.
<span>Mitosis, simply put, is the division of the nucleus of a cell. It is the phase in the cycle of a cell in which the two chromosomes in a cell divide and separate in a nucleus of their own. These chromosomes are completely identical. As a result of mitosis, two identical cells are formed and are known as daughter cells. This process copies and transfers DNA into both the cells that are formed as a result of Mitosis.</span>
Gram-positive microorganisms have a thicker layer of peptidoglycan which traps a greater amount of the gem violet included and upon de-colorizer discharges approximately caught stains.
Gram-positive cell dividers contain a thick peptidoglycan layer with teichoic acids. Gram-negative cell dividers contain a thin peptidoglycan layer that is encompassed by a thick plasma film. Gram-positive microorganisms will recolor purple in view of their thick peptidoglycan cell divider.
Answer:
Background extinction
Explanation:
The background extinction refers to the diminishing of the species at a fairly slow and constant rate. This extinction takes place because of the various environmental factors namely the changing climatic conditions, spreading of diseases, and destruction of habitat. It plays an important role in the natural process of evolution. This has been taking place continuously throughout the geological time and the species are undergoing continuous evolution over a specific period of time.
A drosophila mutant that has legs instead of antennae in its head is caused by a mutation in the phenotype is most likely found in the homeotic genes. The homeotic genes are the one responsible in regulating or formation of the structures in animals. This is likely where the mutation is found, causing the drosophila have legs on its head.
