Mechanical digestion so breaking down of the food in your mouth. Hope this help :)
Answer: 3. The half- life of the isotope must be long enough to capture the age of the rock. and
4. their should be more than one unstable isotope.
In radioactive dating proces, the parent isotope is in unstable state which undergoes decay process to give stable daughter isotopes. Half-life is the amount of time it takes for half of the parent isotopes to decay. The rock dating requires a long lived parent isotope so that it can capture the exact rock age.
One rock when get decayed in the daughter isotope other will be available identify the age.
Answer:
See the explanation below, what is the question you intend to ask anyway?
Explanation:
- Meiosis transmit traits from one generation to the next. It the key process that brings genetic variation into the traits that offspring inherit from their parents. In the life cycle of an organism, meiosis is paired with the process of fertilization.
- Meiosis produces two daughter nuclei with the same number of chromosomes as the parent cell as each other.The chromosomes are re-grouped during meiosis to form new combinations of genes. Genetic reunion is very important as a source of genetic variation.
Answer:
A protein that is destined to be secreted from the cell:
- is targeted to the RER as a soluble protein.
Explanation:
The main function of the RER is the synthesis and transport of secretion or membrane proteins.
If you are looking for the RER you could fount it on eukaryotic cells, side by side of the nucleus, and cover in ribosomes.
