Okay, select the TRUE statements from the following:
A.
Nature and humans have both created very similar types of organisms
B.
Nature selects for variations that help an organism survive
C.
Humans select for variations that help an organism survive
D.
Humans select for variations that provide an advantage for humans
B and C are both true statements.
Match all of the following into pairs.
1. Seedless watermelon
2. Meat chicken
3. Natural Selection
4. Selects for variations that provide a survival advantage
5. Selects for variations because they provide an advantage for humans
6. Could not survive because it cannot run away from predators
7. Artificial selection
8. Could not survive because it cannot reproduce
1. Seedless watermelon - Artificial selection
2. Meat chicken - Artificial selection
3. Natural Selection - Selects for variations that provide a survival advantage
4. Selects for variations that provide a survival advantage - Natural Selection
5. Selects for variations because they provide an advantage for humans - Artificial selection
6. Could not survive because it cannot run away from predators - Natural Selection
7. Artificial selection - Selects for variations because they provide an advantage for humans
8. Could not survive because it cannot reproduce - Natural Selection
A mutation will always lead to natural selection
All mutations will lead to natural selection
Neutral mutations will lead to natural selection
Beneficial mutations will lead to natural selection
Harmful mutations will lead to natural selection
The statement "A mutation will always lead to natural selection" is False.
Not all mutations will lead to natural selection. Neutral mutations have no effect on an organism's survival and thus, will not lead to natural selection. Harmful mutations may decrease an organism's survival and reproductive success, but they do not lead to natural selection. Only beneficial mutations increase an organism's survival and reproductive success and thus, lead to natural selection.
An organism does not adapt to changes in the environment. A population does. This is because;
The above statement is false
An organism cannot change it's alleles but a population already has variations of alleles
It takes many generations for adaptations to occur and a single organism does not live long enough
A mutation must be beneficial to be considered an advantageous trait
The statement "An organism does not adapt to changes in the environment. A population does" is True.
An organism cannot change its alleles, but a population already has variations of alleles. It takes many generations for adaptations to occur, and a single organism does not live long enough to undergo adaptation and pass it on to its offspring. Adaptation occurs when the frequency of certain favorable alleles in a population increases over time due to natural selection. Therefore, it is the population as a whole that adapts to changes in the environment, not individual organisms. A mutation doesn't necessarily have to be beneficial to be considered advantageous in a changing environment; it only has to provide a survival advantage under that specific environmental condition.
