Answer:
Mendel's law of dominance
Explanation:
A pea plant homozygous for purple flowers could have the genotype PP. A pea plant homozygous for white flowers could then have the genotype pp.
This means that all the offpsring have the genotype Pp, see the attached punnet square.
Because the P allele is dominant to the p allele, the plants have purple flowers. This is in agreement with Mendel's law of dominance. This states that for a dominant trait (following a cross of two different homozygous genotypes), hybrid offspring of the next generation will always express the dominant allele.
Answer:
The head of the sperm contains the nucleus. The nucleus holds the DNA of the cell. The head also contains enzymes that help the sperm break through the cell membrane of an egg. The midpiece of the sperm is packed with mitochondria.
Explanation:
The correct answer would be the third option. Phytochemicals are plant compounds with the ability to stabilize free radicals. These are substances produced by plants that functions in helping them to survive over their predators, pathogens and competitors. They can be produced through primary or secondary metabolism. These compounds are considered as research compounds instead of essential substances since they have not been established to have good effects. Some phytochemicals are beneficial to humans while some are toxic and can interfere with the absorption of nutrients in the body. Examples of these compounds are carotenoids, polyphenols, anthocyanins, flavanols, catechins, lignans, isoflavanones and proanthocyanidins.
OPTION C cause that will improve your mindset
Answer:
Psychologists are traditionally concerned with the study of behavior. We believe that many aspects of population, from fertility regulation to migration, may be viewed as examples of human behavior occuring within particular socioeconomic and environmental contexts and thus appropriate for psychological research.
