Answer:
C. 3
Explanation:
Looking at the graph, it goes fastest in the shortest time in sector 3.
The question is incomplete as it does not have the tiles which has been presented in the attachment.
Explanation:
Natural selection is the mechanism by which the species evolve. The species evolve under the influence of the natural pressure due to which the species try to hit and trial method of the adaptive trait. The trait which increases the fitness of a species is passed on to the next generation and the trait becomes established in a population.
This can be observed in the following scenario
1. The hawks predate on the rabbit species with white fur easily as they can be seen from the sky easily.
2. This acts as a pressure on the white rabbits as a result of which the white rabbits to hide themselves mutate and change the colour of the fur from white to brown or tan.
3. The founder effect will eliminate the white fur population from the whole population
4. The population with brown fur will increase with time and the trait will become a permanent trait.
The answer is C, having many specialized parts.
Answer:
Cell membranes, DNA, ribosomes and cytoplasm.
Explanation:
Prokaryotic cells are cells without a nucleus and membrane bound organelles.
Eukaryotic cells are cells with a nucleus and membrane bound organelles, like mitchondria or endoplasmic reticulum.
Both have cell membranes that surround the cell. Both have DNA. In prokayotic the DNA is in a part of the cell called a nucleoid. In eurkaryotic, it is held in the nucleus. Both have ribosomes that make proteins, however prokaryotic cells have fewer. Both have cytoplasm as well.
Therefore, both prokaryotic and eukaryotic cells have cell membranes, DNA, ribosomes and cytoplasm.
Answer:
Because of the fibrous root network of grasses.
Explanation:
<em>Measuring below ground biomass of grass plants is technically impossible and difficult because of the fibrous root network different plants form with one another and within the soil. The network virtually makes it impossible to individually extract all the underground biomass of each grass.</em>
