Answer:

B. White blood cells

Explanation:

The main function of white blood cells is to attack pathogens that enter the body in order to prevent harm from being done to the body.

---------------------------

Plasma's function is to transport nutrients, hormones, and proteins to the parts of the body that need it. It does not fight off pathogens.

Platelets activate when their is a cut or tear on the body. They form together and clot to form a scab. This prevents you from bleeding out. They don't have anything to do with fighting pathogens.

Red blood cells carry oxygen throughout the body. They don't fight pathogens either.

Therefore, the answer is B.

hope this helps!

Covalent compounds are generally not very hard. Justify the statement.
Eduardwww [97]

Covalent compounds are generally not very hard because they are formed by two or more nonmetallic atoms.

<h3>COVALENT COMPOUNDS:</h3>

Covalent compounds are compounds whose constituent elements are joined together by covalent bonds.

Covalent bonding occurs when two or more nonmetallic atoms of an element share valence electrons. This means that covalent compounds will not be physically hard since they constitute non-metals.

Examples of covalent compounds are:

  1. H2 - hydrogen
  2. H2O - water
  3. HCl - hydrogen chloride
  4. CH4 - methane
