The correct answer is option D, that is, ice floating on the water surface.

The cohesive forces among the molecules of a liquid are accountable for the process called surface tension. Surface tension refers to the tension of the surface film of a liquid resulting due to the attraction of the particles in the surface layer by the bulk of the liquid that seems to reduce the surface area.

The examples of surface tension are walking of small insects on water, floating of a needle, the surface tension of water offers the essential wall tension for the creation of bubbles with water, and surface tension is accountable for the shape of liquid droplets.

The low density of ice makes it float at the liquid water surface, like ice cubes in a glass of water, or an iceberg. The lower density of water in its solid form is because of the way hydrogen bonds are aligned as it freezes, the water molecules are pushed further far away in comparison to the liquid water.

Which immune component is deficient in a child who has a congenital immunodeficiency that impairs b lymphocyte function?

Artist 52 [7]

Neutrophils component is deficient in a child who has a congenital immunodeficiency that impairs <u>B lymphocyte</u> function.

Neutrophils- A specific kind of white blood cell that aids in the body's defense against infection and is crucial to the immune system. White blood cells are one of the initial immune cells to react when bacteria or viruses enter the body.

B Lymphocytes- By generating antibodies, B cells are essential for pathogen-specific immunity. Immunoglobulins attached to the surface of B lymphocytes allow them to identify soluble antigens, causing them to develop into plasma cells, which can secrete immunoglobulins and produce antibodies. Primary lymphoid tissues include lymphocytes.

False.

The equipment and tubing might have still been touched or used, even if there isn't blood inside. All equipment should be thoroughly cleaned before use, or if necessary, discarded.

MrRissso [65]

First, let's analyse the options:

Since we're talking about brain damage, there is nothing positive nor cognitive that can be produced.

Since we're talking about schizophrenia, I don't see how the words mood and concordant can relate to the subject.

Answer:

So the most logical answer is "negative". Brain damage is thought to produce the negative symptoms of schizophrenia.

Hope it helped,
