Answer:
cc × cc
Explanation:
This question involves a single gene coding for plant seedling. The green allele (C) is dominant over the white allele (c). This means that the green allele will mask the phenotypic expression of the white allele in a heterozygous state (Cc).
In this experiment where plate 1 only contained white seedlings instead of all green, this illustrates that all the offsprings were recessive. This is because the parental genotypes were both recessive for the color trait i.e. cc.
Note that, the recessive trait can only be expressed when the recessive alleles are present in a gene. Therefore, the parental genotype would have been cc × cc, in order to give rise to all offsprings with the recessive trait (white colour).
Answer:
It would be the first one
Explanation:
I am sure it would be this because when farming, you are not harming the environment or any other ecosystems in anyway. It would also supply food for a constant growing population. Let me know if this helps!
Answer: C) Populations have no effect on their environment.
Ecology is a branch of biology which deals with the relation of organisms with each other and with their surrounding environment. A population can have a negative or positive effect on the environment also, the environment can exert positive or negative effect on the organisms in an ecosystem.
Populations can have negative effects on their environment: Human population utilizes fossil fuels for transportation causing air pollution it is an example of negative effect on the environment.
Populations can affect the size of other populations: Increase in predator population restricts the growth of prey populations.
Populations can adapt to changes in the environment: Organisms undergo favorable adaptation in order to increase chances of survival against changing environment.
On considering the above points this can be concluded that populations have no effect on their environment would least likely show up in his notes.
