Answer: The correct answer is- A) They will all be blue.

As per the information given in the question, blue color (B) is dominant trait in butterflies over the yellow color (b), which is a recessive trait.

As we know that dominant trait always masks the expression of recessive trait.

The possible genotypes for blue color butterfly are- Bb (heterozygous dominant) and BB (homozygous dominant) whereas for yellow color butterfly is bb (homozygous recessive).

Genotypes of the parents are - BB (which will produce gametes, B and B) and bb (which will produce gametes, b and b).

When these parents are crossed, their offspring will have the genotype Bb (heterozygous dominant).

Thus, they will all be blue.

Inessa [10]

Answer:

Cells placed in a hypotonic solution will take in water across their membrane until both the external solution and the cytosol are isotonic. A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution.

Answer:

FRONTAL LOBE

Explanation:

The frontal lobe can be located at the anterior part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe functions and helps in coordination of reasoning, motor control, emotion, and language. It contains the motor cortex, which is involved in planning and coordinating movement; the prefrontal cortex, which is responsible for higher-level cognitive functioning; and Broca’s area, which is essential for language production.

Let say for example Kyle is my friend who was a victim of an accident.

Before the accident, he was industrious and well liked BUT after the accident, he is profane, impetuous, and incapable of working toward a goal.

Such changes in personality would be consistent with loss of impulse control which is a significant frontal lobe function. With connections between the planning functions of the frontal lobe and the emotional processes of the limbic system severed, Kyle had difficulty controlling his emotional impulses, attitudes and abiiity of working towards his goals.
