The statement which is false about the intergumentary system is option D. "Keratin is the pigment responsible for skin color."

Even though the skin color of human beings is affected y different substances, the pigment melanin is responsible for it. Melanin is produced within the skin in cells known as melanocytes and it determines of the skin color of darker-skinned humans.

For instance, the skin color of those who have light skin is determined primary by the bluish-white connective tissue placed beneath the dermis and by the hemoglobin which circulates in the veins of the dermis.

The statement that is FALSE about the integumentary system is that "Keratin is the Pigment responsible for skin color"

<h2>Further Explanation:</h2><h3>Integumentary system </h3>

It is one of the organ system whose functions includes regulating body temperature, retaining body fluids, eliminating waste products and also protecting the body against disease causing pathogens.

Integumentary system is composed of the skin, glands, hair, nails, and nerves.

<h3>The Skin </h3>

It is the largest organ in the body and the main part of the integumentary system.

The Skin is made up of three layers;

  • The Dermis
  • The Epidermis
  • The Hypo-dermis
<h3>The Epidermis </h3>

This is outermost layer of the skin with dermis and hypodermis underneath it.

The epidermis covers the whole body and protects the deeper layers of the skin from external environment and mechanical damage.

<h3>Specialized cells of the Skin </h3>

Epidermis contains some specialized cells that helps in the functioning of the skin.

These cells include;

Melanocytes

They are specialized cells which make a pigment known as melanin. The pigment is responsible for the protection of the skin from dangerous ultra-violet rays from the sun.

Keratinocytes

They are other specialized cells that give rise to a protein known as keratin.

Protein keratin is responsible making the skin tough and water-resistant

Langerhans cells

These are specialized cells whose role is detecting and fighting pathogens that may try to enter the body through the skin.

Merkel cells

Merkel cells are specialized cells that take part in sense of touch.

Keywords: integumentary system, epidermis, dermis, hypo-dermis, specialized cells, keratinocytes, kleratin, melanocytes, melanin, Langerhans cells, Merkel cells.

Is the importance of an element in the body related to its percentage of body weight? Cite the evidence in the table to support
Otrada [13]

Answer:

Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. ... Sulfur is not usually mentioned as a dietary supplement because the body gets plenty of it in proteins. Humans get nitrogen from food. The element is an important component of amino acids, which are used to build peptides and proteins. Nitrogen is also an essential component of the nucleic acids DNA and RNA and all of the other molecules derived from the nitrogenous bases.

Which is an advantage of genetic engineering?
lys-0071 [83]
<span>Great minds combined with technological advancements have a lead to creations and achievements that would have been impossible. Whatever great scientist of the past has achieved have already been surpassed or improved through modern and innovative ideas and processes. An excellent example of which is the direct manipulation of an organism’s DNA, also known as genetic engineering or genetic modification (GM). Coming from the terms genes and modify, the entire process is something out of a science fiction movie. Well, it used to be that way until the practice was perfected and used in actual applications. Genetic engineering made it possible to add new DNA or alter bad ones.</span>

Mitochondria and chloroplasts
Grace [21]

Answer:

C. prokaryotic cells

Definitions

The Mitochondrion is an organelle in the cytoplasm of cells that functions in energy production.

Chloroplast is usually defined as a plastic containing chlorophyll.

Chlorophyll is the green coloring matter of leaves and plants, essential to the production in a bluish-black form, C55H72MgN405 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).  

A root cell is one of the maestro cells in the human organic structure that has possible ability of turning into any of the more than the organic structure's 200 cell types.  

Prokaryotes is any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.

<h2>What are the similarities and differences between prokaryotes, mitochondria, and chloroplasts?</h2>

Both mitochondria and heterotrophic prokaryotes, as well as chloroplasts and autotrophic prokaryotes, have a genetic structure (DNA with a circular double helix shape and the genes themselves), as well as comparable ribosome types. In reality, the endosymbiotic idea is based on these parallels.
