Answer:
The correct answer will be option- Fomite
Explanation:
A Fomite is an inanimate object which carries the pathogen and can transmit the pathogen to a host who touched it.
The fomites are the common cause of the diseases in hospitals where infection can spread by stethoscopes and other objects.
In the given question, since the disease was passed to the person through a pathogen carrying tissue paper which when touche by the person got transferred to the person and caused cold.
Thus, the mode of this disease of transmission is known as a fomite.
Answer:
Ciliated cells are adapted in the respiratory tract to form an epithelial lining of coordinated metachronal ciliary activity that provides the propelling force for the transport of mucus along the airways.

<span>Blowflies burrow into the ground at the completion or, 4th instar stage (17 mm size,) of their larval growth. After burrowing into the ground, the larvae transform into the pupal stage. They remain underground in the pupal stage for 6 to 8 days at which time the adult fly emerges.</span>
Answer:
b) 0.30
Explanation:
An individual who is heterozygous for two linked genes (with alleles A, a and B, b)
i.e Aa & Bb × ab/ab
This cross produce the following offspring
:
14 AB/ab
36 Ab/ab
34 aB/ab
16 ab/ab
Now, the purpose of these calculation is to determine how close together on a gene (gene mapping) these recombinants are.
First, we need to determine the linked gene for the parental chromosomal configurations which are (Aa & Bb × ab/ab) and the recombinant configurations in the offspring which are ( AB/ab & ab/ab). This allows for the calculation of the recombinant frequency; and it is given by:
= 
=
= 
= 0.3
12 is the square root of 144
