Answer:
1. Cytogenetic mapping.
2. Linkage mapping.
3. Physical mapping.
Explanation:
1.<u> Cytogenetic mapping - Gene localization using microscope.</u>
A cytogenetic mapping is defined as the visual appearance of genes when seen by using microscope. The genes are stained and seeing under microscope that shows visually distinct regions, called dark and light bands and provide unique appearance to the genes.
2. <u>Linkage mapping - recombination distance s measured using genetic crosses.
</u>
Linkage mapping is done using linkage analysis by observing the genes linked to the offspring. It do not show physical distances but only shows genetic distances and how the two genes inherited together.
3. <u>Physical mapping - Determine nucleotide sequence distance using DNA cloning.</u>
Physical mapping is a technique by which physical distance between DNA base pairs can be evaluated with the help of DNA makers and also determine DNA base pairs sequences with high accuracy.
Answer:
by comparing external features, behaviors, or physiology of organisms that enhance their survival such as migration, hibernation, or storage of food in a bulb.
Explanation:
<span>An individual generates some 100 kilowatt hours of thermal and kinetic energy a year. Our daily calorie intake from food is re-released throughout the day – at any one time, we’re expending the energy equivalent of a 100 watt bulb – and this alternative energy source can be harnessed. </span>
<span>There are several environmental factors that affect the kinetic energy and diffusion. The environmental factors are temperature, molecular size, and pressure, nature of the material and the concentration of the material</span>
Option D is the correct answer.
To what extent has the presence of a true coelom in animals changed over the course of evolution?
A coelom is a body cavity that is formed from the mesoderm tissue.
Option D - The presence or absence of a true coelom appears to have changed multiple times during the course of evolution.
