Answer:
A
Explanation:
The correct answer choice is not B,C, or D so it should be A
Future generations will have the same frequencies of the A and a alleles as generation 2. Individuals with the aa genotype could be produced.
I don't know if this helps or not but you would want to know the age of the rock (absolute dating) and from there you will be able to know the age of the fossil and what caused it to die.
Answer:
Answer B. Endosymbiosis
Explanation:
Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.
RFLP, AmpFLP are the two techniques which is used to create DNA profile
Explanation:
<u>RFLP technique: </u> RFLP technique stands for “Restriction Fragment Length Polymorphism”. It is molecular method of genetic analysis which allows to identified based unique pattern of restriction enzyme where DNA is cutting in specific regions. It requires large amount of sample. The costing is very high
<u>AmpFLP: </u>The AmpFLP stands for amplified length polymorphism. It is PCR based tool. Firstly, it uses as restricted enzyme. It is cheaper than RFLP technique. It is used as genetic engineering
