Answer:
We have bacteria that live on us, and bacteria have bacterial viruses that live on them. These viruses are called bacteriophages . Viruses differ from bacteria in that they are not made of cells, but instead consist of a piece of DNA (or RNA) packed within a protein coat. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces them cell to produce viral components.
The correct answer is A. Quantitative traits
Explanation:
In genetics, quantitative traits refer to traits or phenotypes (observable traits) that depend on many factors including multiple genes and actions in the environment. These traits differ from other traits because the traits tend to be more diverse in a population. In the case presented, the shell color in clams is an example of a quantitative trait because this phenotype is the result of three different each and each gene contains two alleles which means the color depends on many factors. Additionally, as most quantitative traits there is a higher variation in the phenotype considering clams can have different hues.
Answer:
A physical quantity is a property of a material or system that can be quantified by measurement.
Mixed fertilizer in which the sum of the guaranteed analysis of total nitrogen (N), available phosphoric acid (P2O5), and soluble potash (K2O) totals less than twenty percent. Some examples of single fertilizers are: urea, ammonium sulphate, super sulphate (SP36), TSP, KCL.
The second statement is correct.
