Answer:

so i wanna say ... true?

Explanation:

Most of the Earth's geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes. At a convergent boundary with at least one oceanic plate, an ocean trench, a chain of volcanoes develops and many earthquakes occur.

Cindy is 63 years old and at risk for osteoporosis. Which nutrients would be the most important to consume in adequate amounts t
faltersainse [42]

Answer:

Consumption of adequate calcium and vitamin D

Explanation:

Osteoporosis is a condition whereby there is significant amount of porous partition on the surface of the bone,this disease reduces the density and quality of bone. As bones become more porous and fragile, the risk of  getting fractured is greatly increased.

In a bid to overcome or to be resistant to Osteoporosis, Consumption of adequate calcium and vitamin D is required by the body. This because Calcium performs various function which include;building strong bones, regulating heart beat and fluid balance within cells.

Also Vitamin D works in conjunction with calcium to slow down or even reverse osteoporosis.  That is to say, the body cannot absorb calcium at all without some vitamin D. Hence, Vitamin D is vital in assisting the body absorb and use calcium.

What is an important difference between neurons and hair cells?
BaLLatris [955]

Answer:

2. Hair cells depolarize through an influx of K+, while neurons depolarize through an influx of Na+

Explanation:

The complete question is as follows :

What is an important difference between neurons and hair cells?

1. Neurons detect pressure waves, and hair cells communicate the signal to the central nervous system (CNS).

2. Hair cells depolarize through an influx of K+, while neurons depolarize through an influx of Na+.

3. Neurons release neurotransmitters, but hair cells signal using hormones.

4. Hair cells are only found in the CNS, and neurons are only found in the peripheral nervous system (PNS).

  • Neurons are the cells that are electrically excitable and play a role in transmitting the nerve impulses in the body.
  • Hair cells are found in the ears of the vertebrate and these are the sensory receptors of the auditory and the vestibular system.
  • For the neurons, it is the influx of the sodium ions that causes the membrane potential to become more positive and cause depolarization whereas in the case of the hair cells it is the influx of potassium ions that does so.
  • This reason why the K+ ions move-in is because the surrounding fluid that is the endolymph is richer in K+ ions and does the movement of the endolymph causes the K+ channels to open and K+ influx occurs in the hair cells.

Which of the following statements best describes the termination of transcription in prokaryotes?
harkovskaia [24]

Answer:

B. RNA polymerase transcribes through the terminator sequence, causing the polymerase to fall off the DNA and release the transcript.

Explanation:

Termination of transcription in prokaryotes can be performed in two ways:

  • Rho dependent-Rho factor is a protein that has the ability to bind for RNA polymerase, and to separate it from the template DNA strand
  • Rho independent-there is a specific sequence in DNA  rich C and G nucleotides. As RNA polymerase gets to that region, it folds the DNA and creates the hairpin. The hairpin causes the polymerase to fall.

Damage to _____ and blood vessels can cause lack of feeling in the extremities resulting in amputations.
BigorU [14]

Nerve

Damage to nerve and blood vessels can cause lack of feeling in the extremities resulting in amputations.


Nerves are cable-like bundle of axons and specialized cells (neurons) which make up the nervous system. Nerves transmit messages as electrical signals from one area of the body to another. Nerves are classified into three groups based on the area that messages are conducted. They include; afferent nerves, efferent nerves, and mixed nerves which contain both afferent and efferent axons.
