If it is Not 3-4 Then it should be 2-1!
Answer:Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them.
Explanation:
Answer: They are carbon, hydrogen, nitrogen, oxygen, phosphorus, and potassium.
Explanation: This is what surronds us and what that there is in plants is not as differnt from us if you think about it.
Answer:
C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.
Explanation:
When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.
Answer:
The phenotypes are as follows
Purple, full- 9
Purple, constricted- 3
White, full- 3
White, constricted- 1
Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.
Explanation:
This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).
In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1
Purple color, full pod- 9
Purple color, constricted pod- 3
White flower, full pod- 3
White flower, constricted pod- 1
