Answer:
This question lacks options, the options are:
A. All 270 tall plants were heterozygous
B. All 270 tall plants were homzygous.
C. Only 90 plants were homzygous.
D. All dwarf plants were homzygous.
The answer is D.
Explanation:
This question involves a single gene coding for height in pea plants. The allele for tallness (T) is dominant over that of dwarfness (t). This means that a dwarf plant can only be homzygous recessive (tt) while a tall plant can either be homzygous (TT) or heterozygous (Tt).
According to the question, two tall heterozygous pea plants were crossed i.e. Tt × Tt. Based on this cross, a phenotypic ratio of 3:1 is expected, which is in accordance with the 270 tall plants and 90 dwarf plants (360 total) that was obtained in the cross. Since dwarfism in pea plants is a recessive trait, this means that all the dwarf plants produced in this cross (90) were homzygous (tt).
Answer:
Dorsal horn
Explanation:
The sensory neurons cell bodies are present in dorsal horns. The front side of spinal cord consist of two arms of it. The ventral horn is the centrally located grey matter with motor neurons cell bodies.
The dorsal horns are located at each spinal cord levels that are four in number. The sensory nuclei is present in dorsal horns that perceive somatosensory information. The information is then transferred to midbrain and diencephalon. Thus, Interneurons receiving input from sensory neurons are located in the dorsal horn.
The answer is hematoma. Uncertainty a postpartum woman has severe perineal pain notwithstanding use of bodily ease measures and treatment, the nurse must check for a hematoma by examining and palpating the part. If one is found, the nurse required to notify the main care provider as soon as possible.
