Answer:
One allele is on one chromosome, and the other is in the same position (locus) on the homologous chromosome.
Explanation:
The genotype of an organism refers to the genetic makeup or complete set of genes. The genes control the trait of an organism and exist in an organism in their alternative form called alleles.
Since the alleles are the alternative form of a gene, therefore, they must be present at the same position called a locus.
These alleles are present on the homologous chromosome in which each homologous chromosome is contributed by each parent.
Therefore when the genotype is aa then a and a allele will be present on homologous chromosomes in the same position.
Thus, the selected option is correct.
Answer:
THE EQUILIBRIUM CONSTANT EXPRESSION Kc = ![\frac{[C2H5OH]}{[C2H5OC2H5]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OH%5D%7D%7B%5BC2H5OC2H5%5D%7D)
Explanation:
The equilibrium constant, Kc is an expression given by the ratio of the concentrations of the products over the reactants. TN.B: the activities of pure solids and liquids are equal to 1.
Kc = ![\frac{[products]^n}{[reactants]^n}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bproducts%5D%5En%7D%7B%5Breactants%5D%5En%7D)
where n= no of moles
Reaction equation:
2C2H5OH 
→ C2H5OC2H5
⇒ Kc = ![\frac{[C2H5OC2H5] [H2)]}{[C2H5OH]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OC2H5%5D%20%5BH2%29%5D%7D%7B%5BC2H5OH%5D%5E2%7D)
but [H20] = 1
∴ Kc =
Answer:
Thin fur is helpful in hot environments, but harmful in cold environments
Answer:
Frameshift mutation is caused by the addition or deletion of a base pair in the DNA of a gene.
Explanation:
Frameshift mutation also known as a framing error or a reading frame shift.
Frameshift mutations are due to either insertions or deletions of nucleotides. This causes the entire DNA strand to elongate or to shrink in size.
There are two types of frameshift mutations.They are insertions and deletions. Insertions involve the insertion of one of more extra nucleotides into a DNA chain.
Several diseases have frameshift mutations like HIV, Crohn's disease, cystic fibrosis etc.
Answer:
all of the above
