FrozenT [24]

The given question is incomplete, the complete question is:

Steroids are cholesterol based hormones. Nerve Growth Factor (NGF) is a water-soluble signaling molecule. Both have essential roles in cell function and organismal development. How are they received by the cell? A) Receptors for steroids are located in the plasma membrane and receptors for NGF are located in the cytosol. B) Receptors for steroids and NGF are located in the plasma membrane, C) Receptors for steroids and NGF are located in the cytosol, D) Receptors for steroids are located in the cytosol and receptors for NGF are located in the plasma membrane

Answer:

The correct answer is option D, that is, for steroids the receptors are situated in the cytosol and for NGF the receptors are situated in the plasma membrane.

Explanation:

NGF or the nerve growth factor is the water-soluble signaling molecule, and steroids are the cholesterol-based hormones. Both possess important functions in cell activities and the development of organisms. They are attained by the cells with the help of receptors for steroids situated in the cytosol, and the NGF receptors situated in the plasma membrane.

The plasma membrane permits the hydrophobic molecules, that is, water-insoluble molecules to pass through it. The water-insoluble molecules are the steroids, therefore, it can easily go through the plasma membrane and thus possess receptors within the cytosol. On the other hand, the water-soluble or the hydrophilic molecules are the NGF, they fail to pass through the plasma membrane, and thus, possess receptors on the plasma membrane.

Delicious77 [7]

Answer:

The correct answer is explained below:

Explanation:

  • According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
  • It produces the following gametes: TA, Ta, tA, ta.
  • The heterozygous tall, terminal plant has the following genotype: Ttaa
  • It produces the following gametes: Ta, ta.
  • Crossing them,

           TA                       Ta                     tA                        ta

Ta      TTAa                   TTaa                 TtAa                   Ttaa

     (Tall, Axillary)    (Tall, Terminal)    (Tall, Axillary)    (Tall, Terminal)

ta       TtAa                    Ttaa                  ttAa                   ttaa

     (Tall, Axillary)     (Tall, Terminal)   (Short, Axillary)  (Short, Terminal)

  • The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
  • The phenotypes obtained are:
  1. Tall, Axillary = 3.
  2. Tall, Terminal = 3.
  3. Short, Axillary = 1.
  4. Short, Terminal = 1.
