Answer:
Sharing electrons occurs when atoms have a covalent bond. Covalent bonds occur between non-metals and there are two types of covalent bonds: Polar and Nonpolar Covalent bonds. Polar covalent bonds are when there is an unequal sharing of electrons which causes the atom that occupies the electron(s) more to have a slightly negative charge while the atom that occupies the electron(s) less has a slightly positive charge. Nonpolar covalent bonds basically have equal sharing of the electron(s).
Atoms bond because they need to become stable like the noble gases.
Explanation:
Chloroplasts help them detect light. Chloroplasts are also contained in plants.
Guanine-Cytosine & Adenine-Thymine
Organisms benefit from adaptations because in order for them to survive, they need to adapt to their surroundings. For example, if a shark didnt have fins or a tail, it wouldnt be able to swim and catch its prey.
Answer:
Frameshift mutation is caused by the addition or deletion of a base pair in the DNA of a gene.
Explanation:
Frameshift mutation also known as a framing error or a reading frame shift.
Frameshift mutations are due to either insertions or deletions of nucleotides. This causes the entire DNA strand to elongate or to shrink in size.
There are two types of frameshift mutations.They are insertions and deletions. Insertions involve the insertion of one of more extra nucleotides into a DNA chain.
Several diseases have frameshift mutations like HIV, Crohn's disease, cystic fibrosis etc.
