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:
<span>Depending on the situation, oxygen will be given and the patient will be instructed to breathe very slowly. If it is a panic attack, medication or a shot may be given to slow breathing and stop the attack.
You can prop the patient up so they more easily breathe. Then they will administer oxygen and instruct you to take deep slow breaths. If this is caused by anxiety, further medication may be given.
You might be clostrophobic or there might be a lot of dust in the house which would block the moisture in your lungs. This would make you gasp for air.
You have a preliminary period of just classroom study before they let you loose on patients. This varies, but 6 wks at a minimum .
Don't mean to alarm you but this could be lung leakage or a heart attack symptom. Or you could be suffering from anxiety.</span>
<span>There are three major groups of mammals, categorized on the basis of their method of reproduction. Monotremes lay eggs to have children instead of having the mother bear them. The second type of mammal is the marsupial, which are non-placental animals who carry their young in their pouches. Eutherians are the third group who are placental mammals.</span>
Answer:
Direct observation of evolutionary change: creation of drug-resistant bacteria.
Fossil record: discovery of transitional forms of animals, discovery of shells of extinct organisms
Homology: similarities in mammalian forelimbs, identical genetic code in fireflies and tobacco plants, vestigial pelvis in right whales
Biogeography: resemblance of endangered island species to neighboring mainland species,
