Answer:
The correct option is A. The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.
Explanation:
Recombination will lead to more possibilities for allelic combinations. This will result in increase in the number of genetic variations for a population.. The genetic variations in a population help the organisms to better adapt to different environmental conditions. If genetic variation is low for a population, then there are more chances for the population to become extinct or endangered when disasters occur. Many ecologists blame lack of genetic variation for extinction of different species.
Answer:
(Didn't list features so might be wrong)
distance away from organism to energy source(sun)
the amount of carbon dioxide
the amount of water
the concentration of energy (example; if you were conducting a lab and you use light bulbs as a energy source, higher wattage would be better then lower wattage.)
all of these need to be proportion to each other if you have too much of one thing and not even of the other then the organism will not preform photosynthesis efficiently.
Explanation:
Highschool biology lab
Explanation:
G A T and C are all bits of DNA (deoxyribonucleic acid)
G stands for Guanine A stands for Adenine C stands for Cytosine and T stands for Thymine, when Guanine is in the DNA it always pairs with Cytosine creating G-C and the same is for Thymine and Adenine, when they are sequenced in such a way it just shows how the DNA is placed.
Answer:
Option-1 and 4
Explanation:
Fatty acids can be distinguished into two types: saturated and unsaturated fatty acids.
The saturated fatty acids are the fats that do not contain any double bond as a result of which they are tightly packed and are found in solid-state whereas unsaturated fatty acids are the acids that contain double bond in their structure and are found in liquid form.
The cold-tolerant species show an adaptation to survive in cold species by modifying their cell membrane composition that is they increase unsaturated fatty acids which help in maintaining the fluidity of the cell membrane.
Thus, in the given question option-1 and 4 show, this adaptation and are true options.
