In genetics when an organism is heterozygous that means that it contains 2 different alleles for a specific gene, heterozygous refers to the genotype
Homozygous means the organism carries 2 of the same alleles.
For example there are two alleles for the gene of eye color
B- is the dominant allele for brown eyes
b- is the recessive allele for blue
So if a person's genotype is like Bb then he is heterozygous
but if he is like BB or bb then he is homozygous
Answer:
This happens when the air has a lot of moisture and when the temperature is low (because in this way the water in the air condenses). So if a weather station predicts that warm humid air will pass over much cooler land, the precaution must be to use healights and drive slowly because it will probably be dense fog.

When you drop a ball, it is dropped DOWNWARDS so the number is represented by a negative number. If you toss the ball up it will be a positive number.
To answer your question:
When an object is dropped downwards there will be a negative number since the object is falling downwards.
Answer: B
Explanation:
During polymerization of nucleotides to form nucleic acids, the hydroxyl group on the phosphate group attaches to the 3’ carbon of a sugar of one nucleotide to form an ester bond to the phosphate of another nucleotide. The reaction forms a phosphodiester linkage and eliminates a water molecule.
The DNA strands generally runs from 5 prime to 3 prime direction.
