Yes, the given statement is correct.
When the two traits from each of the parent are inherited, the dominant trait always demonstrates its characteristic even if there is a presence of a recessive trait.
The dominant and recessive terms illustrate the patterns of inheritance of some kinds of traits. For a recessive allele to generate a recessive phenotype, the individual must exhibit two copies, that is, one from each parent. An individual with one recessive and one dominant allele for a gene will exhibit the dominant phenotype.

If the lac repressor were altered so it could not release lactose once lactose was bound to it then you would predict that " the repressor could not bind to DNA".
<u>Option:</u> A
<u>Explanation:</u>
A DNA-binding proteins prevent gene expression coding for proteins engaged in bacterial lactose metabolism is understood as the lac repressor.
Such genes are repressed if lactose is not accessible to the cell, meaning that when lactose is available, the bacterium only spends energy in the development of machinery required for the absorption and processing of lactose.
When lactose is accessible, it is transformed into allolactose, which prevents the DNA binding ability of the lac repressor and thus increases the gene expression.
Answer:
Duration of the magnetic polarity event
Rate at which the plates are moving away from the mid-ocean ridge
Explanation:
The marine magnetic anomaly usually refers to the variation that occurs in terms of the magnetic field strength of the earth. This takes place because of the presence of minerals within the rocks of seafloor that contains high magnetic property.
These magnetic anomalies occurring in the marine rocks cover only about 1% of the total strength of the geomagnetic field. It shows either positive or negative anomaly.
Some of the factors that influence the width of this marine magnetic anomalies on the rocks of ocean-floor includes:
- The amount of time it takes during the magnetic polarity event
- The rate at which the tectonic plates move at a divergent plate boundary from the mid-oceanic ridge.
I believe the correct answer from the choices listed above is the third option. It is oxygen that is a necessary reactant for cellular respiration to occur. Cellular respiration, in a sense, is breaking down sugar in the presence of oxygen. Hope this answers the question.
