Answer:
Explanation:
Endocrine cells in the pancreas are referred to as Islets of Langerhan. There are two major types; Beta cell that produce insulin and alpha cells that produce glucagon.
They are identified when viewed under slides based on their colour reactions with histological dyes. Tinctorial techniques that can be used to identify them under microscope includes; Mallory-Heidenhain azan trichrome, chromium hematoxylin and phloxine, aldehyde fuchsin, and silver impregnation methods.
Islets of Langerhan cells make up minority of the cell. Majority of them are for exocrine functions.
He was looking through a microscope at particles trapped in cavities inside pollen grains in water. The concept of Brownian motion is named after him. This is the random motion of particles suspended in a fluid, liquid or gas resulting from their collision with the fast-moving molecules. Here, the patterns of motion of the particles are typically alternations between random fluctuations in a particle's position inside a fluid sub-domain with a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume.

Question 1
Answer:
D- Different nucleotide combinations code for the same amino acid.
Explanation:
Some amino acid has more than one nucleotide combination coding for it.
Question 2
Answer:
B- Redundancy
Explanation:
Redundancy means that more than one codon is assigned for the coding of most amino acids.
Question 3
Answer:
0%
Explanation:
Since both parents are homozygous dominant and recessive respectively, no crossing can give the homozygous dominant as all offspring are heterozygous.
Question 4
Answer:
Homozygous.
Explanation:
The genotype 'dd' is homozygous since the two letters are both in the lower case.
Question 5
Answer:
25%
Question 6
Answer:
Dihybrid cross
