2. Explain why people with poorly controlled diabetes are at risk for amputation

1 answer:

3 0

People with poorly controlled diabetes are at risk of amputation due to damage of nerves in the extremities of the body. This damage to nerves is caused by chronically high blood sugar. The condition, when it is caused by uncontrolled blood sugar is called diabetic neuropathy.<span>Diabetic neuropathy mostly affects the feet and they lose feeling, such that an affected person cannot sense pain. When they develop an ulcer or small injury to the feet, it may often go unnoticed and with time become infected. High blood sugar impairs the normal healing process and the injury or ulcer may not heal quickly thus compounding the problem. The outcome of this is that the infected part e.g. a toe, may fester and even become gangrenous putting the whole bod at risk and thus the only away to save the rest of the body is removal by amputation.</span>

Prokaryotic bacteria are surrounded by a ____________ that contains the ____________ to regulate the entry and exit of materials

lukranit [14]

Prokaryotic bacteria are surrounded by a cell membrane that contains the transport proteins to regulate the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule, which aids against drying out and protects bacteria from a host's immune system.

<h3><u>Explanation:</u></h3>

Bacteria are the prokaryotic organisms that are found in every part of Earth. These organisms do have an interesting ultrastructure. The coverings of the bacteria are three in layer. They are

A. The outer capsule.

B. The middle cell wall.

C. The inner cell membrane.

The capsule is the outermost covering of bacteria that is formed of different slimy materials. These materials contains hygroscopic substances which can absorb water from the surroundings even when the water concentration in outside is very very low. This layer of protection outside bacteria help them to protect themselves against drying out at dry conditions.

The middle cell wall is formed of polymers of N acetyl glucosamine and N acetyl muramic acid. This layer is chitin in nature and is strong enough to maintain the shape and size of bacteria irrespective of outer conditions.

The innermost layer of bacteria is cell membrane which is formed of proteins and lipids bilayer and this cell membrane contains different transport for proteins which help in transport of different substances like water and nutrients inside the cell by means of active transport or passive diffusion.

Describe the steps in transcription that require complementary base pairing.

nalin [4]

Answer:

Explanation:

Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.

During transcription, the code present in DNA gets transcribed into the code in mRNA. (messenger RNA)

RNA even though is a single stranded shows base pairing.

The pre-mRNA gets created from the DNA.

DNA has two strands, one of these strands acts as coding and another non coding strand.

The DNA shows base pairing with AGTC. [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]

Whereas mRNA base pairing with AGUC. [ U- Uracil ]

Here in mRNA, instead of thymine, uracil gets paired.

According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.

The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.

The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.
