Scientists can also glimpse the awful effects of Alzheimer's disease when they look at brain tissue beneath the microscope:

Alzheimer's tissue has numerous fewer nerve cells and synapses than a well brain.

Plaques, unusual clusters of protein particle, which are construct up between nerve cells. Dead and dying nerve cells contain tangles, which are produce of twisted strands of a further protein.

Scientists are not absolutely sure what causes cell death and tissue deficiency in the Alzheimer's brain, but plaques and tangles are key suspects.

The correct answer is explained below:

Explanation:

Flooding and intrusion of salt water in the low lying areas can adversely affect human life. This can happen in the following ways:

Flooding can cause many people to die due to drowning in the flood water.
Many people lose their habitat and all their belongings due to the entry of water into the settlements having only the ground floors. These people need to rehabilitated to safer regions.
The saline water percolates through the ground and mixes with the fresh water present in the water table, thereby making them saline and non-consumable.
People have to face the dearth of food, drinking water, clothes and electricity until rescue operations are sent.
Increased chance of transmission of water-communicable or water-borne diseases like diarrhoea.

Answer:

e) a drive

Explanation:

We felt thirsty when we have fluid imbalance in our body either we have less water or we have more concentration of osmolytes such as sodium in blood. The brain detect the change produce the effect for the intake of water.

However thirst is a vital primordial emotion that motivates us for fluid intake. So the emotion produces a drive to quench it.
Some recent studies refers it as basic instinct to drink water.

Within a double-stranded DNA molecule, adenine forms hydrogen bonds with thymine, and cytosine forms hydrogen bonds with guanine

vova2212 [387]

Within a double-stranded DNA molecule, adenine forms hydrogen bonds with thymine, and cytosine forms hydrogen bonds with guanine This signifies determining the type of protein produced

DNA's unique structure enables the molecule to copy itself during cell division. The double-helix shape allows for DNA replication and protein synthesis to occur. Each of the two strands in double-stranded DNA acts as a template to produce two new strands.

Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
