If water molecules inside and outside of a cell became non polar , how would the transport of materials in and out of the cell b

postnew [5]

<h2>Answer:</h2>

The water will move in and out freely. The material transport which is due to the water transport will be affected.

<h3>Explanation:</h3>

Water is a partially polar molecules. Many ionic compounds and ions travel inside and outside the cell due to attachment with water molecule.
As well as water movement is controlled due to its polar nature through cell membrane. and the cytoplasm and outer environment is separate due to non polar cell membrane.
If the water become non polar then the movement through cell membrane will be easy for water. And the molecules dissolved in water will also be transported uncontrollably.

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.

Sequencing eukaryotic genomes is more difficult than sequencing genomes of bacteria or archaea because of the _____.

AlekseyPX

Are there options? because there are lots of answers.

Firstly, eukaryotic DNA tends to be much longer; it's held inside a nucleus, so it has to be separated from the rest of the cell; and there are also mitochondria in most eukaryotic cells, which have their own RNA, which has to be separated.
