DNA is replicated in the nucleus of eukaryotes, but in the cytoplasm of prokaryotes. Why is this?
umka2103 [35]

Answer:

In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.

   In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that  transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.

The nurse is teaching a client with recurrent urinary tract infections (utis) ways to decrease risk for additional utis. the nur
lana [24]

To prevent UTIs, the nurse teaches the client to void (empty) immediately after sexual intercourse.

<h3>What are urinary tract infections (UTIs)?</h3>
  • UTIs are commonly occurring infections that occur when the bacteria, quite often from the skin or rectum, enter the urethra and infect the urinary tract.
  • The infection may occur in any part of the urinary system i.e. the kidneys, bladder and the urethra.
  • These infections are commonly occurring in women.
  • The symptoms include pelvic pain, strong urge to urinate, pain with urination, cloudy urine and blood in the urine.
  • To prevent UTIs, drink plenty of water, empty your bladder soon after intercourse, drink cranberry juice and avoid irritating feminine products.
  • The easiest way to prevent UTIs is to flush the bacteria immediately out of the urinary tract before it starts to grow there. Therefore, drink lots of water.

Explain biomagnification

There's an excess of Phosphorus in soil, the plants consume it, then the primary consumers consume multiple plants, and have a higher level of phosphorus concentration in them. Then secondary consumers consume multiple primary consumers and the phosphorus from all the things they ate are concentrated in them, and so on. Basically, even though as energy is passed along the food chain, it lessens with each trophic level, nutrients become more concentrated and the highest trophic level has the highest concentration because of how many organisms were consumed.

It would be most difficult for the body to maintain homeostasis if over several days someone had an inadequate intake of:_______
Liula [17]

If someone had an inadequate intake of sodium over several days, it would be most difficult for the body to maintain homeostasis.

<h3>Why is sodium important for homeostasis? </h3>

Most of the sodium in our body is present in the extracellular fluid (ECF). The concentration of sodium in the body is measured relative to the amount of water in the body.

Maintaining proper sodium concentration is therefore essential for maintaining water balance in the body. It also helps in the proper functioning of neurons by assisting in the conduction of impulses.

Sodium concentration is also important for muscle contraction. Proper sodium concentration maintains osmolality of the extracellular fluid which maintains the volume of blood and plasma in the body.

Therefore, an inadequate intake of sodium, over several days will affect the homeostasis of the body.
