Answer:
Asexual reproduction involves only 1 parent. The daughter cells / offspring are the exact clones of the parent. There’s no variety. The end products are only 2 daughter cells. Sexual reproduction involves 2 parents (a mate). The offspring consists of a mixture of genes from both parents. There’s more variety to the offspring. 4 daughter cells are produced in sexual reproduction. Both undergo cell division. Asexual reproduction = mitosis Sexual reproduction = meiosis. Sexual reproduction produces the gametes, asexual produces body cells
Explanation:
Determine the mass in grams of each element in the sample. If you are given percent composition, you can directly convert the percentage of each element to grams.
For example, a molecule has a molecular weight of 180.18 g/mol. It is found to contain 40.00% carbon, 6.72% hydrogen and 53.28% oxygen.
Convert the percentages to grams.
40.00 grams of carbon
6.72 grams of hydrogen
53.28 grams of oxygen
Answer:
A) The shared electrons in C-O bonds spend less time close to the carbon nucleus than the shared electrons in C-H bonds.
Explanation:
The electronegativity from H is 2.2, from C is 2.55 and from O is 3.44. This property is the measure of the attractive force between an atom and a pair of electrons.
So, the difference of electronegativity of H and C is smaller than the difference between O and C. Because oxygen is more electronegative, the electrons stay close to it in the bond C=O. So carbon has a partial positive charge in that bond. For the bond C-H, the shared electrons stay closes to carbon.
