Given question is incomplete as it lacks the group of choices. However, the group of choices associated with the question is as follows:
1. Organisms must display variation.
2. A trait must increase reproduction.
3. A trait must directly affect metabolism.
4. A trait must increase survival.
5. A trait must be able to be passed on to future generations.
Answer:
The correct answer is : option 3. A trait must directly affect metabolism.
Explanation:
The process that leads to change or adaption in the species or a population of the organism known as natural selection. In this process population exhibits the variation in the population due to the change or adaption.
This variation refers to the better traits and increased reproductive ability, suited to the environment than others which is also known as survival of the fittest as they increase their survival in comparison to the other population or species. Natural selection carries traits that are passed on to one generation to another.
Thus, the correct answer is option Is : 3. A trait must directly affect metabolism.
The longest phase of mitosis is prophase. Because the nuclear membrane disappears, Nucleolus disintegrates, and the DNA condensed to form chromosomes (each chromosome is composed of sister chromatids attached around centromere.)
This type of asexual reproduction is called apomixis.
Apoximis is reproduction by special generative tissues without fertilization. It includes parthenogenesis in animals, in which the new individuals develop from unfertilized egg, and apogamy in certain plants in which the generative tissues may be the sporophyte or the gametophyte.
Yes they do have a cell wall
