A tall pea plant (Tt) is crossbred with a short pea plant (tt). The following Punnett square shows the separated alleles for two

pea plants.
Punnett square showing female parent across the top with a phenotype of tall and a genotype of Tt and a male parent across the side with a phenotype of short and a genotype of tt. Inside the top left box 1 is written, inside the top right box 2 is written, inside the bottom left box 3 is written, inside the bottom right box 4 is written.



Which of the following shows the correct match of the box numbers and the genotype of the offspring?

1 = Tt; 2 = tt; 3 = Tt; 4 = tt
1 = Tt; 2 = Tt; 3 = Tt; 4 = Tt
1 = Tt; 2 = Tt; 3 = tt; 4 = tt
1 = Tt; 2 = tt; 3 = tt; 4 = tt

The answer is the first one. For one and three, the "T" from the mother is crossing with a "t" from the father. On two and four, both of their "t"s are crossing and that's why those are both tt. So, your answer is the first one.

Measurement of physiological arousal in breathing rate, hear rate, and blood pressure (which can mark emotional response) is als
zysi [14]

Emotion is one of the responses of an organism (whole) which involves physiological arousal. Other than indicating emotion, physiological arousal or heightened physiological activity is modernly used in polygraphs. Polygraphs or lie detector notes changes in blood pressure, pulse, respiration while the subject is asked and answers questions. It is based on the assumption that dishonest answers are indicated with physiological arousal.

inn [45]

Question: Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production?

(A) As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.

(B) As tissue osmolarity rises, less ADH is released, causing less water to be excreted as urine.

(C) As tissue osmolarity rises, more ADH is released, causing more water to be excreted as urine.

(D) As tissue osmolarity rises, less ADH is released, causing more water to be excreted as urine.

Answer:

As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.

Explanation:

ADH is the hormone that triggers the formation of concentrated urine by stimulating the absorption of water from the filtrate in the kidneys. As the solute concentration (osmolarity) in the blood raises, the more of the ADH is released into the blood. ADH triggers reabsorption of water in collecting duct and distal tubules and thereby, reduces the water loss in urine. Increased reabsorption of water restores the osmolarity, blood volume, and blood pressure.

In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction
attashe74 [19]

Answer:

DNA replication

Explanation:

DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.

The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.
