<span>The answer is c. Chromosomes carry the codes for hereditary traits. Chromosomes are thread-like structures made of proteins and DNA. Codes for hereditary traits are present in a molecule of DNA. Chromosomes can be found in the nucleus of each cell. Humans have 46 chromosomes in each cell (not 460) arranged in 23 pairs (not 230). Hope this helps. Let me know if you need additional help!</span>

Answer:

The correct answer is option c.

Explanation:

Chromosomes refer to the compositions found within the nucleus of the cell that comprises genes of an individual. The genes refer to the DNA segments, which comprises the code for a particular protein, which functions in one or more kinds of cells in the body.  

A chromosome comprises thousands of genes, and each of the normal human cell comprises 23 pairs of chromosomes, thus, a sum of 46 chromosomes. More than one gene present within a chromosome determines a trait known as a gene-determined characteristic. This trait or characteristic passes from one offspring to another. Thus, it can be said that the chromosomes carry the codes for hereditary traits.

Opsonization.

Explanation:

  • Complement proteins and antibodies coat a microorganism and provide binding sites, enabling macrophages and neutrophils to phagocytize the organism. This phenomenon is termed opsonization.

Opsonization occurs as a result of binding of a molecule called opsonin to the epitope of a pathogen.

Opsonization helps the immune system to select and kill the infected cells instead of targeting all the cells in general.

2. Keratinocytes
The make up the majority of the cells in the epidermis. They synthesize keratin which are proteins that make up your hair, skin, and nails. They can also be found in other organs inside your body.  

3. Melanocytes
These cells can only be found in the stratum basale. They synthesize melanin with a brown to black pigment. These dark pigments serves as protection for the skin from harmful UV rays. 

4.Merkel cells
Merkel cells are also known as <em>tactile cells</em>. They are the sensory receptor for touch. Merkel cells and the nerve fiber together are called the Merkel disc. 

5. Dentritic cells
They are also known as <em>Langerhans cells</em>. They can be found in two layers of the epidermis: the stratum spinosm; and stratum granulosm. They are what you call macrophages that come from the bone marrow. They serve as immune cells that provide protection against toxins, microbes and other pathogens that try to penetrate the skin. 

Hope you find some information above that will help you.
