A dominant trait can be shown both when an organism is homozygous dominant AND heterozygous. Two different genotypes give the same visible result so a testcross is needed to be able to accurately say if the organism is homozygous dominant or heterozygous
Answer:
d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.
Explanation:
Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.
Their active sites are primary protein 3D structure for binding with substrates during reactions.
Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,
This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites occupied, therefore denying the inhibitor methylalchol chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites
The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine. Simply, A combines with T and G combines with the C. It is often called as a complementary base pairing because of each base pair bonds only with its specific complementary base partner in a DNA molecule.

A solid minute object that is said to come together for the formation of the planet and are believed to produce cosmic dust are called planetesimal.
The options that best describes the planetesimals are:
- Option A. They are the origins of planets.
- Option B. They formed from gas and dust.
- Option D. They are believed to have developed in debris disks.
The descriptions can be explained as:
- It is believed that planets formation occurred through planetesimals. The formation happened from gas, dust particles and debris.
- By the process of accretion, the discs coalesced and became bigger and solid over time. This bigger mass started attracting other matters towards each other because of gravitational force.
- This pull resulted in either breaking or creation a bigger mass of pieces known as planetesimals. The collision continued to become bigger and solid planets we know today.
Therefore, options A, B and D are correct.
