Converging mirrors or concave mirrors reflect light through its surface that bulges inward, and away from the incident light. It is used to focus light towards one focal point.
This makes it capable to produce a real image when the object is located at a distance greater than a focal length from the mirror's surface.
Trees in the rainforest are so tall because they compete for sunlight. Hope this helps!
Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
The Depressant effect of starvation is impaired cognitive
abilities, anxiety and chronic depression. The lack of nutrient supply and
dehydration caused by it are such that thinking abilities are lowered causing
irrational behaviors like irritation, aggression and anxiety. Starvation can also induce depression.
Proteins is the substance in prokaryotes which contain sulfur.
