Answer:
The two main processes of cell division, meiosis and mitosis, have in common their main steps. In both cases the metaphase ( pairing of homologous chromosomes), anaphase (migration of chromosomes to the ends) and telophase (beginning of DNA decondensation and cell division) are very similar.
The greatest difference occurs in prophase I of the meiosis, which involves the process of recombination (cross over), resulting in variability in the gametes.
Another difference is that meiosis is a reductional process, where the final result of meiosis will be gamens with half of the genetic information, and in mitosis both cells will be equal.
Answer:
If he or she doesn't look like dad, it might be because he or she hasn't gone through the environmental pressures that will cause the change. If your father's child works outdoors or spends a lot of time outside, there's a good chance that he probably has darker skin than your child.
Answer:
RER
Explanation:
The proteins and lipids, essential for building the cell membrane, are
manufactured by the rough endoplasmic reticulum
The atomic number of oxygen is 8
The atomic number of zinc is 30
The atomic number of Lithium is 3
The atomic mass of oxygen is 15.999, for zinc it is 65.39, and Lithium is 6.941
The number of protons for oxygen is 8, for zinc it is 30, and for Lithium is 3.
The number of neutrons for oxygen is 8, for zinc it is 35, and for lithium is 4. To find the number of neutrons you have to do atomic mass - atomic number.I rounded the answers to find the #of neutrons.
The number of electrons is always the same as the number or protons so the answer is for oxygen 8, zinc 30, and lithium 3.
I hope this helped you. If you can please make branliest :)
