<span>If star A is farther from Earth than star B, but both stars have the same absolute magnitude, the option which is true about their apparent magnitude is that star B has the greater apparent magnitude.
Apparent magnitude refers to the magnitude of an object in space as it is actually measured from the earth, whereas absolute magnitude refers to the star's brightness.

Cancer is the disease that results in uncontrolled cell growth.
The epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.
Epithelium is one of the major types of body tissue that line the outer surfaces of organs and blood vessels throughout the body.
The epithelium performs the following functions that include:
- protection,
- secretion,
- secretion, absorption,
- excretion,
- filtration,
- diffusion, and
- sensory reception.
There are also different types of epithelium found in different parts of the body. A typical example is the simple cuboidal epithelium.
Simple cuboidal epithelium are single layered epithelium that are as tall as they are wide (cuboidal in shape).
They are found lining areas that are active in secretion and absorption.
Therefore, the epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.

Answer:
the correct answers are as follows
12:
b. Testcross- an organism with dominant phenotype but unknown genotype is crossed with homozygous recessive organism for the same trait. Based on the results obtained, if all offsprings have the same phenotype, then the parent is homozygous, but when a 1:1 ratio is observed in the offsprings, then the parent is heterozygous.
13.
e. Watson and Crick- they both used the crystallographic images from Franklin, analyzed them to first elucidate the 3D structure of the DNA and propose it to the world.
14.
c. Intracellular and commonly found in the cytoplasm- the receptors of steroid hormones are generally present within the target cell either in the cytoplasm or nucleus, since they alter gene expression.
15
e. Certain prokaryotes/bacteria- this is a process that will enable disease-causing pathogens to communicate and cooperate with their group, by the release of autoinducers that increase their cell density.
Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
