Answer:
C. Desertification.
Explanation:
This is mainly caused by overgrazing and other human and natural activities in this areas. When desertification happens in a land area, it hampers the land ability to support life; affecting wild species, agricultural crops, domestic animals and people. Its negative effect includes famine of the inhabitants, also mass migration, as it can also cause extinction of some organisms or species.
Answer:
False
Explanation:
Nuetrons have a neutral charge. They aren't positive like protons. They aren't negative like electrons.
Answer:
The fertility factor or the F factor signifies a plasmid in some bacteria, which allows the conduction of genetic substance from a donor cell to the recipient by the process of conjugation, leading to recombination.
The genotypic difference between the F- cells, F+ cells, and the Hfr cells are that the F- cells are devoid of the F factor, the F+ cells possess autonomous F factor, that is, a segment of DNA, which can replicate autonomously in the cell. In case of Hfr, the F factor is integrated into its chromosomal DNA, thus, they carry an integrated F factor.
Oh, we actually did a similar project in my biology class!
I looked at your punnet squares and they all looked right to me, so I will just explain how to find the genotype and phenotype.
Ok, so let me explain that for genotype they mean the letters, so for example if the penguin has a dominant trait, the genotype could be Ff, or recessive could be ff. By phenotype they mean the trait expressed, so if the penguin is dominant for freckles, the phenotype would be has freckles.
Now I don't know what your teacher wants you to do, but in my class we just flipped a coin to decide whether we would use the dominant or recessive trait.
Hopefully that clears it up a little bit for you :)
