Answer:
A compound microscope is an upright microscope that uses two sets of lenses (a compound lens system) to obtain higher magnification than a stereo microscope. A compound microscope provides a two-dimensional image, while a stereo microscope provides a three-dimensional image.
Explanation:
The steps involved in herpes simplex virus lytic cycle are: attachment on the epithelial cells. Penetration of the herpes virus inside the cell. Uncontrolled replication of the virus takes place. The virion gets assembled and finally released by bursting the cell.
Explanation:
The lytic infection of the virus results in breaking of bacterial or any cell after its replication.The lytic infection is phage infecting bacteria and getting replicated and bursts the cell of bacteria.
There are 5 stages in which lytic infection takes place in any virus like herpes simplex virus:
Attachment on bacterial cell wall:
penetration of virus
biosynthesis
maturation
release of virions
During the infection the HSV genes are expressed in the epithelial cells and get replicated resulting in sores and irritations as in genitals.
the cycle is generally 18- 20 hours long.
Answer:
Incomplete dominance
Explanation:
The traits in the organisms are controlled by the genes which are present in the form of two alleles on the chromosomes. Each allele represents the variant of the trait which is determined when these alleles unite during sexual reproduction.
The allele can be dominant when it shows its effect or it can be recessive when it is suppressed during fusion.
In the given question, the studied trait is the pattern of the hair which is present in two variants: the curly hair and the straight hair. When the parents for these traits were crossed they produced offspring which was intermediate between the curly and the white hair. This intermediate trait shows that neither of the two alleles which control the trait is dominant and the trait blended. This natural process is known as incomplete dominance.
Thus, Incomplete dominance is correct.
Orbital period is the <span> time taken for a given object to make one complete </span>orbit around another object. Mercury orbits the Sun in 88 days. Therefore, Mercury's orbital period is calculated by (88/365.25) or .241 Earth years. Hope this answers the question.
