Answer:
Law of Independent assortment
Explanation:
Gregor Mendel, who was regarded the father of Genetics, discovered principles that governs inheritance in his experiments. He discovered that the alleles of a gene will separate into gametes when he performed a crossed involving a single gene or character like height, pea color etc. He proposed his law of segregation based on this.
However, he considered two characters or genes in his cross, which he called a DIHYBRID cross. He discovered that the alleles of each different gene separates into gametes independently of one another i.e. without one gene influencing the other in each gamete. He called this principle his LAW OF INDEPENDENT ASSORTMENT.
He obtained a 9:3:3:1 phenotypic ratio for the F2 dihybrid offsprings which is only possible if each gamete equally likely contains two alleles of the two different genes in different combinations.
The endocrine gland is the one that is ductless an release its secretion directly in bloodstream example liver, pancreas, etc. The given statement is true and the correct option is B.
<h3>What is endocrine gland's secretion called?</h3>
The secretion of endocrine gland is referred to as hormones, which are chemical messengers that helps in body's control and coordination.
The endocrine gland is the one that is ductless an release its secretion directly in bloodstream example liver, pancreas, etc.
Thus, the given statement is true and the correct option is B.

Answer:
a. Paper chromatography would separate the pigments into several bands that appear green or yellow/orange.
Explanation:
The primary or main pigment in plants is the chlorophyll. The chlorophyll gives plants their characteristics green colour and helps in the absorption of light during photosynthesis.
Other pigments in plants include carotenoid with its characteristic yellow, red or orange colour; anthocyanin with its re/blue colour and betalains with its red/yellow colour.
<em>Hence, if pigments from a particular species of plant are extracted and subjected to paper chromatography, one would expect the pigments to be separated into several colour bands ranging from green to yellow/orange.</em>
The correct option is a.
