Explanation:
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell.
Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Answer:
False.
Explanation:
Linked genes are the genes that are present on the same chromosome and can undergo the process the recombination. The recombinant progeny are obtained by the crossing of the linked genes.
The recombinant frequency and map distance can be deduced by the mapping of the linked genes. The genotype of the heterozygote cannot be deduced by examining phenotype and sometimes the recombinant progeny is completely different from the parents as well as from the heterozygotes.
Thus, the correct answer is false.

The probability of long hair is 50%. The probability of short hair is also 50%. So, the probability of one of their offspring having long hair is 50%
Answer:
Simple cuboidal epithelia are found in areas that stretch.
Explanation:
The simple cuboidal epithelium consists of a single layer of cuboid cells with a centrally located nucleus. The cells of this epithelial tissue are mostly involved in secretion and absorption and therefore, are found in the lining of ovaries, lining of kidney tubules and gland ducts.
Transitional epithelium is like a stratified cuboidal epithelium when not stretched. Its cells become flatter when the tissue is stretched. It has multiple cell layers and elasticity and therefore, is found in the lining of the urinary bladder and parts of ureter and urethra to allow stretching of these organs.
