Answer:

Permanent tissues are composed of cells, which have lost the power of cell division and moulded into anparticular form according to their function.

The cells of permanent tissue are mature and have definite shape, size and function.

The cells maybe living or dead, either thin walled or thick walled.

The cell wall is composed of cellulose, hemicellulose, pectin and lignin.

"a nurse notes that an infant with a diagnosis of failure to thrive who has been receiving tube feedings for 3 days has very dry

Cerrena [4.2K]

The infant is suffering from dehydration most probably from esophageal atresia (non-development of the distal side of the esophagus, forming a closed tube) or partial/complete gut obstruction. With a urine output of 250 mL constantly, the patient will be dehydrated. The infant is diagnosed with failure to thrive and is most probably malnourished (most common cause of failure to thrive in infants is preterm birth). In the presence of esophageal atresia, along with retained feedings, the patient will also present with vomiting. In the presence of partial/complete gut obstruction, the patient will also present with distension of the abdomen.

What is the purpose of cells?

Nezavi [6.7K]

Explanation:

Hey there!

The main function of cell is to make a life possible in the universe by performing various type of vital activities.
Various type of cell performes various type of activities. The same type of cell combine together to form tissue. Similarly, similar tissue combine and form organ. Now, Organs combinly form form a system and all system form a whole body. They combinly perform task for sustaining life in the universe.
Cancer are caused mainly due to abnormal growth of cells. It shows various type of symptoms. Such as;

The wounds donot heal faster, instead it may be worse.
Unwanted bleeding may occur from nose, mouth, or other parts.
You may see lump in some parts of body.(Thickness of skin).
They also may have problem of hair loss in more amount.

Hope it helps...

Which of the following sequences is correct for the downhill movement of electrons during cellular respiration? A. glucose – cit

Volgvan

Answer:

B. glucose – NADH – electron transport – O2

Explanation:

This is the sequence from glycolysis in which glucose molecules are split down to pyruvate, to oxidative phosphorylation.

During this process the electrons are released from glucose molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .

The makes the carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .

The electrons from above are transferred in hydrogen atoms to matrix by these co-enzymes.Where the H is split to electrons and protons.

The electrons for the ETC, produce the PMF for transporting protons into the intramembrane space.

The concentration of protons generated the electrochemical gradients which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.

The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.
