By damaging transportation, communication, and everyday schedules. These are a few ways that natural disaster might weaken a public area. Lives taken might slow workers and progressiveness due to mood swings and depression. Jobs also become rarer because of raw destruction.
I hope this helps! :)
Explanation:
Stratified cuboidal epithelium and stratified columnar epithelium can also be found in certain glands and ducts, but are uncommon in the human body.
The sugar that is produced in photosynthesis is a glucose.
- Glucose can be used to provide energy for cellular activity.
- Excess of glucose is transformed into starch. Starch is transported into storage organs.
- Glucose can be transformed into cellulose, pectin, and chitin. These molecules are structural materials for the cell walls.
- Fats and amino acids can be formed from glucose. These molecules can serve as structural materials or can be stored.
Answer: D is wrong
Explanation: gametes are haploid. The haploid number in humans is 23. The diploid number is 46.
Answer:
low level of calcium would result in fewer signals sent between pre and post synaptic cells.
Explanation:
The calcium has a main role in signal transmission mechanism and here is the mechanism :
1-the impulse reaches the synapse (depolarization which is a voltage change).
2-the voltage gated calcium channels open and let calcium flow into the cell.
3-the calcium causes the synaptic vesicles to rupture and release chemical transmitters which cross the synaptic cleft and finally bind to receptors on the post synaptic cell (transmitting the signal)
so it's obvious that if calcium concentration decreases, the signal transmission also decreases.
