b. 1000 X 16.
c. 1000 X 22.

Answer:

<h2>a.  1000 X 2^8</h2>

Explanation:

As given;

Initial population of bacteria= 1000;

Log phase growth is exponential phase, period in which bacteria gets double.

Generation time= 15 minutes;

it means, bacteria get double in every 15 minute,

so after 2 hours, bacteria will have 8 generation times;

so the final generation of bacteria is =1000 X 2^8.

Final bacterial generation after two hours = 256,000(1000 X 2^8)

<h2>(Answer 2 points 3)</h2><h2>B. Taxonomy</h2><h3>1. the science of the classification of organisms.</h3><h2>Explanation:</h2>

A taxonomy is said to be a scheme of classification or in other words, we can also define the term taxonomy as the branch of science involved with classification, especially of organisms, systematics. Organisms are grouped together. This science of gives name, describe and classify the organisms including all the plants, animals and the microorganisms of the world.

<h2>(Answer 3 points 3)</h2><h2>C. Family</h2><h3>4. A taxonomic category containing a group of similar genera.</h3><h2>Explanation:</h2>

Family is the one that has been classified between order and genus. A family is also divided into the subfamilies. It is one of the eight main and important taxonomic levels. It is a primary taxonomic category of organisms ranking. This category comes on the sixth number of all the categories lies in a taxonomic group.

<h2>(Answer 4 points 3)</h2><h2>D. domain</h2><h3>2. The largest taxonomic category.</h3><h2>Explanation:</h2>

In the three-domain system of taxonomy, if we talk about the domain then we would define it as the superkingdom or empire. It can also be said to be as it is the highest taxonomic rank of organisms. It is a taxonomic category above the kingdom level. There are three domain such as Bacteria, Archean, and Eukarya, which we can say are the major categories of life.

The answer is A: convergent boundary zones. The various Japanese islands formed due to the subduction of the Philippine Sea Plate below the continental Amurian Plate and Okinawa Plate to the south, and subduction of the Pacific Plate under the Okhotsk Plate to the north. This occurred during the mid-Silurian to the Pleistocene . This explains why much of Japan is mountainous.
