Oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
C÷C-C-C
1-2-3-4 (left to right)
The ÷ represents the triple bond.
C1 is triple bonded to C2, as well as bonded to a H.
C2 is triple bonded to C1, as well as bonded to C3.
C3 is bonded to 2 H's, as well as C2 and C4.
C4 is bonded to C3, as well as 3 H's.
(Hope this helps, it's difficult to make a diagram on phone).
A. Become cancer because in the process of mitosis (cell replication) idlf the cell replication does not work properly and keep going on and on it will begin creating mutations to help it replicate causing cancer to happen.
Ex: let's say you have a paper cut. Your blood cells must replicate in order to close that gap in your body. They begin replication but if they get out of control and begin creating mutations it will turn into cancer.
Answer:
yes, sexual reproduction leads to the selection of better individuals for a particular environment
Explanation:
Natural selection can be defined as a mechanism associated with the survival and reproduction of individuals better adapted to their environment. Sexual reproduction is able to increase genetic variation, which is the primary source on which natural selection works. In consequence, individuals that exhibit an evolutionary adaptive phenotypic variant will have more chance to survive and to reproduce than those individuals with other less adaptive traits, thereby leading to evolution of the population and tending to optimize phenotypic variants for particular environmental conditions.
