The correct answer is <span>C. You cannot view live specimens because the necessary preparation kills cells. </span>
The answer is pretty self-explanatory. Unlike it, regular microscopes can view living creatures such as bacteria or similar.
Answer:
Assuming the dominant allele is represented as A, and the genotype as AA and the recessive as a, and genotype as aa; then the F1 will produce the offispring. Aa, Aa, Aa,Aa in ratio: 1:1:1:1:1
This shows the dominance of allele A.
However if two of the F1 generation are crossed then:
The F2 is AA,Aa,Aa,aa the phenotypic ratio is
3 ; 1
W<u>hile the Genotypic ratio is ratio;</u>
<u> 1AA : 2Aa Aa; 1aa(1 ;2;1)</u>
Explanation:
Hello there,
One is crossing over. This allows both parents genes to intertwine resulting in chromosomes with different genetic diversity.
Another option is fertilization. This creates genetic diversity by allowing each parent to contribute their unique set of genes to a zygote.
Hope this helps!
Answer:
d
Explanation:
b/c hydrogen fuel cells are uses car energy.
18. Enzymes bind with chemical reactants called substrates. In some reactions, a single-reactant substrate is broken down into multiple products.
20. stored evergy is released whenever these chemical bonds are broken in metabolic processes such as cellular respiration. Cellular respiration is the process by which the chemical energy of food molecules is released and partially captured in the form of ATP.
