Answer:
Similarities: both are chemical messengers, both can have (but don't necessarily have) similar structures (made from amino acids), both can be produced by the central nervous system (hypothalamus produces some hormones), certain molecules can act as both hormones and neurotransmitters (example: norepinephrine).
Differences: neurotransmitters are released by neurons across a synaptic gap, have very short distances to travel, and act very quickly on the neighboring cell. Hormones are released by glands and often have to travel longer distances, which means that they are slower-acting. Also, hormones are typically used for regulation (negative feedback) while neurotransmitters are used for stimulation of a neighboring cell.
Explanation:
The question has been answered itself but the answer will contain the detail explanation.
Answer:
1. The replication fork formation during DNA replication is important for the continuity and the addition of the further base pair on the template. The DNA initiation process starts by the formation of replication fork.
2. The okazaki fragments are the short DNA fragments that are formed on the lagging strand. These fragments are later joined by the enzyme DNA ligase.
3. Leading strand is the continuous strand that formed during the DNA replication. The direction of the leading strand is 5' to 3' .
4. DNA polymerase is the main replicating enzyme during the DNA replication process. Different types of DNA polymerase with multiple subunits are present in prokaryotes and eukaryotes.
5. The new DNA that are formed from the parental strand and complementary with each other are called daughter DNA.
Answer:
Molecules stop moving at freezing point. Helium has the lowest boiling point. The molecules move very quickly at boiling point.
Explanation:
Heating up- molecules move faster. Cooling down- molecules move slower
Answer:
D) Apes and chimpanzees are thought to have evolved from a common ancestor.
Water is attracted to ions, such as sodium, potassium, phosphate, and chloride ions. Maintenance of normal intracellular fluid volume depends largely on the intracellular concentration of potassium and phosphate ions. Maintenance of extracellular water volume on the other hand depends primarily on the extracellular concentration of sodium and chloride ions.
