The answer is;  A


This model hypothesizes how life started during the early conditions of the earth which were hot and filled with greenhouse gases in its atmosphere about 4 billion years ago. It is explained by the theory of spontaneous generation where organic molecules were created from inorganic molecules spurred from energy from lightning. These organic molecules filled the water bodies and chemically arranged themselves, over time, into primordial life.

In which type of rock would you find a large amount of silica?
____ [38]

Answer:

igneous

Explanation:

Igneous rock is the type of rock that contains a large amount of silica. Igneous rocks are formed when molten rock (magma or lava) cools and solidifies. Silica is a common component of magma, so igneous rocks are often rich in silica. Glass, which is also made from silica, is not a type of rock. Metamorphic and sedimentary rocks are formed through processes that do not involve the melting of rock, so they typically contain lower amounts of silica.

Answer:

BENEFITS:

The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.

A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.

The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.

LIMITATIONS:

<u>descriptive  method  of  investigation </u>

It cannot be used to correct variable or be used to determine causes and  effect  of  the  problem

<u>experimental  method  of  investigation </u>

It might create an artificial situation that do not always represent the real  life situation

<u>comparative  method  of  investigation </u>

It  is not easy to control other variables that might influence the study

Why are viruses considered as peculiar microorganisms? <br><br><br><br><br> Plese answers
Aleksandr [31]

Answer:

Because they can only reproduce in a living cell

Explanation:

Virus is an organism that is incapable of replicating on its own without a living host. A virus infects a living host and makes use of Its replicational ability to produce new virions. A virus consists of a genetic material surrounded by a Protein called CAPSID. It does not possess the characteristics of other living organisms.

This means that it does not carry out any of the features a living cell undergoes e.g reproduction, respiration etc. Due to this reason, it is not classified as a living thing. They don't possess organnelles that carry out this peculiar functions.

A virus is considered a peculiar microorganism because it can only live and reproduce in a living host cell.
