In dog gametes, there are half the chromosomes contained in normal diploid cells. In the normal diploid cell of the dog there are 78 chromosomes, thus, in dog gametes, there are 39 chromosomes.
Similarly, in deer mouse brain cells there are 48 chromosomes since brain cells are diploid cells.
In gametes there are half of that number, so in deer mouse gametes there are 24 chromosomes.
Answer:
c. Grasses and small shrubs would be the first plants to begin growing from the seeds that are in the soil.
Explanation:
This question depicts SECONDARY SUCCESSION, which is one of the two types of ecological successions where an area previously occupied by living organisms is disturbed by natural causes such as hurricanes, tornadoes etc. This is the case in this question where thunderstorms that lead to tornadoes leave a significant impact on the environment of the southeastern part of the United States.
According to the question, the tornado results in the uprooting of previously existing trees that has occupied that area. After the devastating effect of the tornado on the environment, changes occur rapidly since the soil of the environment are already rich in nutrients. The first plants to recolonize in secondary succession are annual plants consisting of grasses and shrubs whose seeds were not destroyed by the tornado. These forms of plants can also be called PIONEER species as far as secondary succession is concerned.
Hence, based on the question, grasses and small shrubs would be the first plants to begin growing from the seeds that are in the soil.
