The correct answers are a, c, d.
There are three types of capillaries: continuous, sinusoidal (or discontinuous) and fenestrated. Continuous capillaries are the most common type and they form tight junctions. Sinusoidal capillaries form an incomplete lining with several gaps, which allow red and white blood cells and some serum proteins to pass. These capillaries are mainly found in the bone marrow, lymph nodes and adrenal glands. Finally, fenestrated capillaries facilitate the movement of smaller molecules and plasma proteins and are mainly found in the small intestine. The majority of the fluid transport happens through the fenestrated capillaries.

The epidermis is composed of five cell types. match each type to its description.
WITCHER [35]
Listed under are the 5 different type of cells found in the epidermis and their description:

1. Stem cells
These are what you call undifferentiated cells. These are cells found in the stratum basale, which is the deapest layer of the epidermis. These cells divide to create keratinocytes. 

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.

Cellular respiration can best be described as Group of answer choices using energy released from breaking high-energy covalent b
pochemuha

Answer:

using energy released from breaking high-energy covalent bonds in organic molecules to force ATP formation from ADP and phosphate.

Explanation:

The cellular respiration involves the generation of energy for bodily activities. This is technically known as the Kreb's Cycle or citric acid cycle. This is the process through which the intracellular metabolism of glucose takes place. Specialized organelles, called mitochondria are responsible for the process. The organelles ensure that the breaking of the high energy phosphate bonds in the ATP monocle generate energy. Overally, the process is a hydrolysis process. This involves the movement of the hydrogen ions an the generation of 38 high energy phosphate bond breakages.

What happens when consumers eat producers in the energy pyramid? A Energy transfer forms from the producer to the consumer. B en
Dafna11 [192]

Energy transfers from the producer to the consumer.

Explanation:

  • An organism eats to get energy that is required by its tissue to carry out  metabolic activities.
  • Organisms in an ecosystem are related to each other by there feeding habits.
  • The producers lie at the bottom of a food chain. They bear the ability to convert the solar energy into chemical energy within the cell.
  • They are responsible to drive the flow of energy from the ultimate source into the food chain.
  • When consumers feed on the producers the energy conserved in the tissue of producers get transferred to the consumer in this way the enery transfers from one trophic level to another.
