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.
Answer:
Option D, Gastric Juices
Explanation:
The second line of defense is a non specific defense mechanism in which no specific individual is targeted but all invaders are killed in general way. Some common mode of second line of defense are - Phagocytic cells (white blood cells), inflammatory responses, macrophage system etc. The second line of defense comes into action when the invader has surpassed the first line of defense which include either physical barrier like skin, mucous membrane, hair, cilia etc. or chemical barriers like gastric juices, saliva, Hyaluronic acid etc.
Hence, gastric juice does not belong to second line of defense.
Thus, option D is correct.
Infrared: (of electromagnetic radiation) having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves.Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.
Ultraviolet: (of electromagnetic radiation) having a wavelength shorter than that <span>of the violet end of the visible spectrum but longer than that of X-rays.</span>
