Answer:

B) Radiometric dating

Explanation:

Radiometric dating: Is a method used to date material such as rocks or fossil by comparing its radioactive isotope material contained in it with the amount of it's decay products. Since the decay occurs at a constant rate Scientists/Geologists are able to obtain it's relative age.

Answer: Option B.

Radiometric dating.

Explanation:

Radiometric dating is a technique used by geologists gist to determine the relative age of rock through their decay rate or the decay of their radioactive elements which occur naturally when they are formed.

The radioactive decay is the process where the atomic nucleus that is not stable losses energy through radiation.

What are the differences in their hard parts, distribution, reproduction among phytoplankton of cyanobacteria, diatom, coccolith

Margarita [4]

Answer:

Explanation:

DIFFERENCES BETWEEN HARD BODY PARTS.

•Cyanobacteria have calcified sheaths.

• Diatoms have hard but porous cell wall.

• Coccolithophores have hard body parts.

• Silicoflagellates skeleton is composed of opaline silica.

• Dinoflagellates do not have hard body parts

• Green algae - no hard body parts.

• Brown algae - no hard body parts.

DIFFERENCES BETWEEN DISTRIBUTION

• Cyanobacteria are found almost in every terrestrial habitat on planet.

• Diatoms are found in oceans, freshwater, soil and damp.

• Coccolithophores are exclusively marine.

• Silicoflagellates are found in marine environment.

• Dinoflagellates are both freshwater and marine.

• Green algae grow on objects that do not move such as substrate, rock.

• Brown algae - wide distribution from tropical to polar zones.

DIFFERENCES BETWEEN REPRODUCTION.

• Cyanobacteria - asexually by binary or multiple fission, fragmentation, spore formation.

• Diatom - asexually by cell division through mitosis.

• Coccolithophores - asexually by binary fission.

• Silicoflagellates - asexually

• Dinoflagellates - asexually

• Green algae - sexually or asexually by cell division, fragmentation, spore formation.

• Brown algae - sexually and asexually.

<h3>What is a Book Review?</h3>

This refers to the literary analysis of a book to show the content and to convince people to read or to write criticisms about it.

Hence, we can see that from the given book review, the reviewer notes the content of the book and how it is of high quality, and his word choice such as "colorful characters", "exciting action sequences", etc helps to create ethos.
