Explanation:
Differentiation
Embryonic stem cells contain sets of genes; these are expressed to determine their cell type. This differentiation process is regulated via cellular signalling to switch genes on or off.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.
Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.

Fossils, they show us many different things, for example dinosaur bones show us how they acted in the past, and links to what animals that are still alive today. Second, is that fossils, human fossils turn into Carbon to which makes diamonds and coal to help us in everyday life. And finally, Fossils show us how living things have changed over the years.
I hope that helps, to be honest I'm not good at science either but I hope you get better soon..
Vance is demonstrating conceptual knowledge
Conceptual knowledge is the clear and detailed understanding of principles, concepts, models or theories and the understanding of the linking relationships between them. Conceptual knowledge is acquired by thoughtful, reflective learning, listening, reading, or viewing. From the question, Vance is demonstrating conceptual knowledge because he has the explicit understanding of why rainfall amounts affect different types of vegetation positively and others negatively.
Answer:
Answer is opioids.
Explanation:
The opioids are drugs like opiums, and perform similar function like opium.
They are useful for the treatment of moderate and severe pain by acting on opioid receptors. The drug is also usuf in suppressing cough and diarrhea. It has side effects like sedation and nausea.
It should be noted that, a long term exposure to this drug can lead to drug tolerance, ahich can be described as physical tolerance and probably , withdrawal symptoms. Example is narcotics.
