1) compound mutagens can go about as base analogs
Analogs are perceived by DNA polymerase and consolidated into DNA set up of nucleotides and after that reason change by base-matching in a way that varies from the undifferentiated from nucleotide. For instance, 5-BrdU can be consolidated inverse An amid replication and after that combine as a C amid the following round of replication, making a TA CG change.
2) substance mutagens can synthetically adjust base.
Compound adjustment of bases changes their base-blending properties to such an extent that an altered purine will base-match with the wrong pyrimidine and the other way around. For instance, EMS is an alkylating operator that proselytes guanine to O6-methylguanine, which base-sets with T to make a GC to AT progress
Hi, In my opinion, bat will be the most closely related to hawk.
Why?
This is because, when we consider the photo of a bat and a hawk, we notice the similarities like:-
• Wings- They have nearly the same short wings decreasing the area of contact with air and enabling higher flight area.
• Presence of small snouted beak-like structure and presence of less or more similar color.
• Both live in trees and are normally not companiable with humans.
• Hawks and bats are both having a similar anatomy, not body, I meant that they have similar positioning of organs like stomach, pancreas etc.
• They have the sense of locating prey miles away, enabling easier locating of food.
Hope this helps...

In human, Reproduction is done when two gametes i.e a sperm and an ovum fuse to give a zygote and eventually an offspring.
<h3><u>
Explanation:</u></h3>
Reproduction is the process by which a living organism can produce more individuals of same species to continue a race. Reproduction is of various types - asexual reproduction and sexual reproduction.
But in human, only sexual reproduction is seen. Here in human, males do produce sperms in their testis from the sperm mother cells by means of meiosis. Females do produce ovum in their ovary by means of meiosis from ovum mother cell.
Now the fertilization in human is internal fertilization which is achieved by means of coitus or sex between a male and female, where the male inserts his penis into female vagina to release the sperms. These sperms do swim into uterus and then into ampulla region of fallopian tube where it meets the ovum, and fertilization occurs. Then the zygote swims to uterus by passive movements and settle there which is called implantation. Then eventually the cell divisions lead it into a multicellular embryo and then after a gestation period of about 278 days, the baby is delivered. A new offspring is born.
The answer would be fluid permeability!
