Answer:
D. The offspring of multi-cellular organisms tend to be identical to the parent.
Explanation:
The offspring of multi-cellular organisms which reproduce through sexual mode can never be identical to the parents because of <u>crossing over</u> which is a phenomenon which occurs during <u>meiosis</u>. All the individuals which have sexual dimorphism and reproduce sexually have germ cells in their gonads. Meiosis is a type of cell division which occurs only in germ cells not in somatic cells. <u>During meiosis the genetic material from both the parents is exchanged leading to new combinations of genes</u> as a result of which offspring is neither 100% identical to father nor to the mother. Offspring displays traits which are a combination of both the parents thereby showing variability.
Answer:
A mechanical brake applies a friction force to convert the kinetic energy of the vehicle into thermal energy which then dissipates into the atmosphere. As with any system, the process of braking must follow the principle of conservation of energy.

b. phosphate. The polar head of a phospholipid is negatively charged and is made up of phosphate molecules. This polar head region attracts water (hydrophilic) and is positioned outward to interact with water.
You can rub a permanent magnet against something else that can be magnetized, like a paper clip.
Answer:
A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. For example, the gene for eye color has several variations (alleles) such as an allele for blue eye color or an allele for brown eyes.
