Answer:
false ig because animal cell is not complex(i am not sure)
It depends! If we're talking about something like a cute little Matlipoo, your answer is yes. These are technically considered mutants as they posses characteristics that are not found in either of the original populations (Maltese + Poodles). Not all mutations are bad. Those who survived the bubonic plague are said to have a mutated gene that enabled them to be more resilient against the illness.
In the case of inbreeding the mutation can prevent offspring from being born by either causing sterility in the parents, or it will cause a miscarriage so the fetus is terminated naturally in the beginning. Sometimes the offspring is still born (deceased at birth), or has debilitating symptoms like in cerebral palsy. So there is a chance that the offspring may never be born, making it impossible for a breeder.
Mutations can also be spontaneous, so a breeder might mean well by selecting two animals from different family trees, but both of the parents could produce mutant offspring together.
This question is pretty vague, you should ask your teacher for clarification.
Answer:
A hypothesis that is not possible, or has less strength, to explain how life arose on Earth is that it originated from cells that were delivered by meteorites from outer space (option D).
Explanation:
Although it is a hypothesis that has scientific foundations to be considered, the origin of life coming from organic molecules or cells from space -called Panspermia- has not been completely proven because:
- It provides information on the origin of cells or organic matter, but it doesn't specify how life was formed from them.
- It does not resolve the question of how a cell could withstand a journey through space or endure the high temperatures when a meteorite entered the primitive atmosphere.
These arguments make the hypothesis of the arrival of the first cells from outer space the least accepted today.
