Answer:
Basement membrane
Explanation:
Epithelial tissues is one of the four types of tissues. They are widespread throughout the body and form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands .
They perform a lot of functions such as absorption, excretion, filtration, diffusion, and sensory reception.
They are anchored to the underlying connective tissue by basement membrane. A thin, fibrous, extracellular matrix of tissue.
The basement membrane acts as a mechanical barrier that prevents malignant cells from invading the deeper tissues.
Answer:
Each ribosomal subunit has three binding sites for tRNA: designated the A (aminoacyl) site, which accepts the incoming aminoacylated tRNA; P (peptidyl) site, which holds the tRNA with the nascent peptide chain; and E (exit) site, which holds the

In the case of the gene that determines high cholesterol in the blood, the two alleles express incomplete dominance.
What this means is that the dominant allele is not completely dominant over the recessive allele. If the allele was completely dominant, even one allele would be enough to determine the individual's trait as dominant. But in the case of incomplete dominance between the alleles, the heterozygous individuals that have one dominant and one recessive allele are an ''in between'' phenotype.
