Answer:

Adrenaline

Explanation:

The adrenaline glands, located on top of both kidneys, are glands that produce hormones to regulate blood pressure, bodily functions, metabolisms, etc. Adrenaline is released whenever the blood is redirected towards the muscles, causing surges of energy. In general, adrenaline increases blood flow in your body, which causes the heartbeat to increase, or give the feeling of a racing heart. Between the football players and the heartbeat rate, they are getting rushes of adrenaline from either participating in the game or cheering on their team from the sidelines. Hope that made sense.

Consider a cross to investigate the pea pod texture trait, involving constricted or inflated pods. Mendel found that the traits

nirvana33 [79]

Answer:

C. 217

Explanation:

Mendel obtained the phenotypic ratio of 3 dominant: 1 recessive in the F2 generation of a monohybrid cross. According to the given information, inflated pods are dominant over the constricted one.

Let's assume that the allele C is responsible for inflated pods while the recessive allele "c" gives constricted pods. A cross between two pure breeding plants with inflated (CC) and constricted pods (cc) would give all the plants with inflated pods (Cc) in the F1 generation. A cross between two F1 plants would obtain F2 generation in following ratio=3 Inflated: 1 constricted.

Therefore, if 650 plants with inflated pods were obtained in the F2 generation, 217 plants must have constricted pods since 650:217 is almost equal to 3:1.
