Answer:
A. Redshift and Blueshift
Explanation:
It’s red shift and blue shift, because this only occurs when the frequency of the wave is made longer or shorter due to the movement of the source relative to the observer.
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.
Answer:
Queen ants have two main responsibilities first, Queens are the founders of all ants colonies. A queen and will leave the colony she was born into a mate with flying male ants. After mating, she will scurry off to find a new location for her nest, lose her wings and lay her first hatch of eggs.
Glucose, amino acids, lipids and glycerol.
Explanation:
Carbohydrate is broken into glucose molecules
protein is broken into amino acids
Lipid is broken into fatty acids and glycerol.
Starch present in the food is broken to glucose molecules to yield energy.
Protein is digested in stomach by the action of pepsin, trypsin and chymotrypsin.
Glycosidic bonds of starch is broken down by salivary and pancreatic amylase enzyme.
fat is acted upon by lipase enzymes from pancreatic and intestinal juices.
these are broken into smaller units so that gets absorbed by blood and carries throughout the body.
