Mutation. this happens when a cell copies its DNA to divide. its more common than you may think, a "typo" occurs every 100, 000 or so nucleotides, thats about 120, 000 "typos" every time a cell divides.

A) myoglobin binds the oxygen by means of iron
B)myoglobin would be an effective O_2-transport in other tissues
Explanation:
Answer:
Cross a non-floppy-eared male to a floppy-eared female and observe if males offspring have the floppy ear trait
Explanation:
Mammals (e.g. dogs) have two sex chromosomes: X and Y. In the XY sex-determination system, the female gamete (i.e., the ovum) contributes to an X chromosome, while the male gamete (i.e., the sperm) contributes either an X chromosome or a Y chromosome: normal females are XX and normal males are XY. In consequence, a male always inherits its X chromosome from the mother and its Y chromosome from the father. In this case, the presence of the floppy ear trait in all males F1 offspring obtained by crossing a non-floppy-eared male to a floppy-eared female indicates that this trait is linked to the X chromosome because males inherit the floppy ear trait from the mother.
If the student uses alternative energies, the environment is pared the impact of global warming and release of particulate matter.
<h3>Impact of alternative energies</h3>
All over the world, fossil fuels have been the dominant source of energy for several households. The impact of these fossil fuels is increase in the amount of carbon dioxide and particulate matter released into the environment.
If the student uses alternative energies, the environment is pared the impact of global warming and release of particulate matter.

Answer:
Six hours
Explanation:
Given that;
A microbiologist inoculates a flask of broth with 1 ml of 100 bacterial cells/ml
Also, the generation time of the species is 1 hour and there is no lag phase
i.e there is no period where the individual bacteria are maturing, this will enhance a faster replication
So , since the generation time is 1 hour and we are being given 100 bacterial cells/ml
∴
After 1 hour = replication of the bacterial cells would have been doubled to =200 bacterial cells
2nd hour = 400 bacterial cells
3rd hour = 800 bacterial cells
4th hour = 1600 bacterial cells
5th hour = 3200 bacterial cells
6th hour = 6400 bacterial cells
∴ We can see that at the 6th hour, the culture has contained more than 6,000 cells/ml
