Answer:
The reason hydrogen bonding occurs is because the electron is not shared evenly between a hydrogen atom and a negatively charged atom.
Explanation:
Hydrogen in a bond still only has one electron, while it takes two electrons for a stable electron pair. Any compound with polar covalent bonds has the potential to form hydrogen bonds.
Answer:
( Going from left to right )
- Prophase -
- Telophase & Cytokinesis -
- Anaphase -
- Metaphase -
Explanation:
Prophase - Chromatin condenses making the chromosomes visible.
the nuclear envelope breaks down - makes it look like it has butterflies
Remember: The "PRO-phase" gets -butterflies- when it's about to start a race, but he lost so he starts to have a -break down-.
Metaphase - The chromosomes become aligned at the "center" or equatorial plane.
Remember: metaphase in Greek means "between" and "stage" and during this stage, the chromosomes stop moving back and forth, and also there are kept in the middle of the cell !!
Anaphase - sister chromatids separate and the resultant daughter chromosomes move toward the poles.
Remember: Sister Anna has a twin they both move out of their home and separate. One moves to the north pole and the other lives in the south pole.
Telophase - Daughter chromosomes reach the poles and form two new nuclei.
Remember: Anna and her twin settle in their new homes and both of the sisters throughout the year have two children or "nuclei" each, and also call each other on the "telephone" almost every day. :)
hope this helps <3

All things that are living are made of cells.
Answer: 23
Explanation: One pair of the 23 chromosomes, known as sex chromosomes, determines at conception whether a fertilized egg will develop into a male or female. Today, human females have one pair of identical X chromosomes.
