Answer:

POLLUTANT, SOURCE AND IMPACT

Carbon Monoxide

SOURCE:- carbon monoxide main sources are from our homes, eg; wood stoves and fire place, generators, gas stoves, kerosene heaters, leaking chimneys, tobacco smokes etc

IMPACT:- carbon monoxide can cause organ failure as it reduces the amount of oxygen the hemoglobin been carried in the red blood cells to this organs in our body.

Carbon dioxide

SOURCE:- carbon dioxide can be from both human and natural source. Example of the sources includes; natural source ( ocean release, decomposition and respiration), human activities ( burning of coal, oil and natural gas, cement production etc)

IMPACT:- carbon dioxide causes difficulties in breathing as it displaces oxygen in the air.

It also increase the greenhouse effect (global warming) as more heat energy gets trapped by the atmosphere causing the planet to become warmer.

Sulphur dioxide

SOURCE:- sulphur dioxide mainly occur due to human activities such as fossil fuel combustion at industrial facilities, in ships etc.

IMPACT:- Sulphur oxide has been linked to many health effect and diseases such as cardiovascular diseases. It also causes respiratory problems, asphlegm and asthma attacks, irritation of lungs, throat and nose as well.

Nitrogen oxides

SOURCES:- nitrogen oxides also comes from human activities such as; combustion of fossil fuel, making of nitric acid, refining metals as well as petrols, explosive, food manufacturing etc.

IMPACT:- Nitrogen oxides has also been linked to many respiratory health issues such as bronchitis and wheezing. It causes the lining of the lungs to inflame there by reduce the immunity of the lungs to respiratory diseases.

Methane

SOURCE:- methane can be from either natural or human activities. The natural source includes; food digestion by cattles, decay of organic materials. Human activities such as waste management, rice production, oil and gas production etc.

IMPACT:- Methane is considered a green house gas like carbon dioxide, it contributes to the trapping of heat energy in the atmosphere which causes global warming. It is also linked to serious health issues such cardiovascular, respiratory and neurological problems.

Particulates

SOURCE:- particulates are fine tiny particles of matter found in the air, it might be in solid or liquid form. Example; dust, smoke, fumes etc. This particles can suspended in the air for an extended periods of time.

IMPACT:- exposure to particulates can cause variety of respiratory health problems such as difficulties in breathing, coughing, lungs and heart problem etc.

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{Option A}$

<h2>_____________________________________</h2><h2>Mutations:</h2>

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

<h2>_____________________________________</h2><h3>DELETION:</h3>

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

<h2>_____________________________________</h2><h3>DUPLICATION:</h3>

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

<h2>_____________________________________</h2><h3>SUBSTITUTION MUTATION:</h3>

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

<h3>INSERTION MUTATION:</h3>

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.

<h2>Previously understood similarities that seemed to connect slime molds and fungi are now considered to be examples of convergent evolution</h2>

Explanation:

Convergent evolution is an evolutionary process where unrelated monophyletic organisms independently develop or evolve similar characteristic traits due to the need to adapting to similar conditions or ecological or environmental necessity.
The slime molds are subsets or part of amoebozoans but have certain morphological features similar to that of fungi, this type of evolutionary behavior is called convergent evolution.
Under stressful conditions, slime molds produce and develop spore-generating fruity bodies like fungi, which is a convergent evolutionary change.

Damage to which portion of the limbic system results in loss of memory of recent events and difficulty committing anything new t

slamgirl [31]

Answer:

The correct option is D. (Hippocampus)

Explanation:

Hippocampus is known as the part of the brain and situated in the bottom middle section inner folds which are called the temporal lobe. The main function of the hippocampus is memory and learning. It plays an important role in retrieve two types of memory which are known as declarative memories and spatial relationship memories.

1) Declarative memories: It is related to events and facts such as learning how to memorize lines.

2) Spatial relationship memories: It is related to routes and pathways such as when a driver learns pathways through the city.
