Answer:

A. Oxygen atoms in water molecules are also attracted to hydrogen atoms in other water molecules.

Explanation:

Water molecules are forge by hydrogen bonds with one another. Here, the partly negative charge on the Oxygen (O) of one molecule would forge a hydrogen (H) bond with the partly positive charge on the hydrogens of its neighbouring or other molecules. Water molecules can also form a bond with other polar molecules and ions.

In the diagram, H is white and O is gray coloured molecules.

The bacterial species,<u> Listeria monocytogenes</u>, accounts for 12%-15% of infant meningitis cases.

Explanation:

Listeria monocytogenes is a group B strep gram-negative bacteria, one of the main causes of meningitis.

This species is psychrotrophic in nature which means that it can grow at low temperatures like refrigerator temperature and mostly found in areas with a temperature around 15-20 degrees Celsius.

These organisms also become psychrotolerant or psychrophiles and can grow at places where the temperature fluctuates.

This is the main reason for the spoilage of food stored in a refrigerator. So leftover baby foods, bottles stored in a refrigerator can be contaminated with these species.

When the infants ingest the contaminated food or use the bottle, they also get infected. Listeria monocytogenes cause meningitis in infants especially who are immunocompromised infants.

<h2>Disruptive Selection.</h2>

Explanation:

Disruptive selection is also known as Diversifying selection.

Disruptive selection helps in determining the changes which is seen in population genetics,

The disruptive selection favours those individuals which have the smallest and largest values of the trait or characteristics.
These individuals possess the highest fitness.
The individuals which have an intermediate values have lower fitness.
The example of Disruptive selection is seen in Male lazuli buntings Feather colour which is also kown as Passerina amoena.
Passerina amoena is a bird species which is native to North America.

aalyn [17]

Answer:

hippocampal place

Explanation:

A type of cell that fires when rats are in a specific location as opposed to some other locations are known as place cells.

Generally, place cells are specially shaped neurons whose origin is the hippocampus. These neurons fire or become more active when animals are in certain locations in its environment, as opposed to their overall environment.

The cells are from regions CA1 and CA3 of the hippocampus and collectively act as a cognitive representation of these locations where they are limited to firing. The locations where the neurons are limited to firing are referred to as place fields.

Hence,<u> the cells found in the rat as shown by the illustration are referred to as the place cells whose origin is the hippocampus.</u>
