Whats are the functions of the integumentary system ?

Verdich [7]

Answer:

Absorption

Thousands of pores on the surface of the skin can absorb vitamins, acids, water and oxygen in order to provide moisture and nourishment to our skin.

Excretion

The skin is the body’s largest waste removal system. Toxins are released through the sweat glands and pores.

Secretion

The skin secretes sebum, a mixture of oils that keeps the skin soft and supple. The layer of sebum on the outermost layer of the skin is known as the acid mantle. When intact the acid mantle has a PH that ranges from 4.5-5.5. The acid mantle is acidic in nature to protect the skin from outside invasion.

Regulation

The skin regulates the body’s temperature by sweating; when water from sweat on the skin evaporates it gives off heat and cools the body. The body’s temperature increases or by shivering or getting goosebumps when the body is cold. The contraction of muscles releases energy that warms the body.

Sensation

The skin contains millions of nerve endings that transport stimuli. These nerve endings allow humans to detect sensation such as heat, cold, pain and pressure.

Answer:

okay so im guessing they want you to compare 2 different land resources. Say a water power station and a coal mine for example.

you could state the different effects the coal mine would have in comparison to the water station.

the coal mine say has pollution produced as a result in producing the energy. Whereas water has a lot better environmental value, but might cost more to produce energy

there is a lot of information of the 2 on google :)

Why is gene regulation necessary in the development of multicellular organisms??

irga5000 [103]

<span>It's important to regulate genes so it does nothing unnecessarily. This will help it save energy. Different specialized cells and factors control the making of genes and the way they do it depends on its environment. The regulators can be turned on and off depending on why and how t needs and uses things around it. There are also necessary factors that allow gene regulation. E Coli must regulate the lac gene so it is used properly. If there is lactose around it, it must be switched on to process it. If there is no lactose around, then it must turn off to save energy because there is no reason for it to be in use.</span>

Answer:

<em>1. The characteristic thing about </em><em>adult frog breathing</em><em> is that </em><em>drawing in air by lowering their mouth floor</em><em> (option d).</em>

<em>2. The substance released by the </em><em>lung secretory cells </em><em>is the </em><em>surfactant </em><em>(option c).</em>

<em>3. The main divisions of the </em><em>peripheral nervous system</em><em> are the </em><em>somatic and autonomic systems</em><em>.</em>

Explanation:

<h3>1. Breathing of the adult frog</h3>

The adult frog - while out of the water - uses a nasal breath, propelling air into its throat and oral cavity. The air content in the frog's mouth causes the internal pressure of the cavity to increase, and the floor of the mouth is modified to allow the passage of air to the lungs.

Under water, the frog's breath is cutaneous, that is, through its skin.

Adult frogs do not have gills or respiratory muscles.

<h3 /><h3>2. Pulmonary surfactant </h3>

Pulmonary surfactant is a substance produced and secreted by the pulmonary epithelium, specifically by type II pneumonocytes. The function of the surfactant is to keep the pulmonary alveoli open to allow gas exchange.

The surfactant is a substance of a lipidic and proteic nature that helps reduce the surface tension of the water, which in the socket prevents closure when the air is exhaled.

Another function is to prevent the germs - viruses and bacteria - present in the air from passing from the alveolus to the bloodstream.

<h3 /><h3>3. Divisions of the peripheral nervous system</h3>

The peripheral nervous system is dependent on the central nervous system and is made up of all the nerves that go to each of the tissues and organs of the body. It is divided into somatic and autonomic nervous systems.

<u>Somatic nervous system</u> is composed of nerves that drive nerve impulses to skeletal muscles, being predominantly voluntary. The involuntary response in this system is due to the existence of reflex arcs, whose center of integration is the spinal cord.
<u>Autonomic nervous system</u> is responsible for the innervation of coughs the internal organs, allowing their function under the coordination of the central nervous system. It is an involuntary system and is subdivided into sympathetic and parasympathetic systems.

The integration of both systems, somatic and autonomic, allows a body to perform all its functions, including the function of relationship, alertness and maintenance of organic homeostasis.
