Answer: Rivers
Explanation: Runoff from cars and other pollutants usually flow off of roads into rivers or streams that usually lead into bigger bodies of water such as oceans.
The organelles that produce proteins used within the cell are the ribosomes.
Final answer: Ribosomes.
A. Pre-eclampsia
Pre-eclampsia also
known as pregnancy induced hypersion or toxemia. It is a pathological condition
in pregnancy that is characterized by hypertension, edema and proteinuria.
However, pre-eclampsia is a symptom that is associated with late pregnancy that
encompasses both convulsive and non-convulsive stage.
The answer will be depends. Usually, pesticides and herbicides are used by farmers to control the attacks of pests on their plants. However, pesticides and herbicides can sometimes be the reason why the plants did not grow naturally. If there's a better natural alternative way to control pests, then surely this will help agriculture sustainability.
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.
