Answer:
I believe its because the blood from Mouse A had anthrax in the blood stream so it is still in the blood when yu put it into Mouse B so then Mouse B develops the same thing Mouse A had.
Explanation:
Answer:A. Codominance
Explanation:
This is a type of genetic inheritance where neither of the genes is dominant over another. Thus both pair of the gene are expressed on the same LOCUS equally with none masking another. Therefore an individual receive both allele of a heterozygous gene, and have equal phenotypic expression
An example is the AB blood group in man, where both allele present on the same locus are fully expressed with no one dominant over another.
Incomplete dominance refers to a blend of alleles where one does not have full dominance over another another, therefore gives a new phenotypic expression different from both alleles.
e.g pink flower allele in four o'clock flower.
Answer: C
Explanation: The two chromatids of a duplicated chromosome are held together at a region of DNA called the centromere. Centromeres are the attachment points for microtubules, which are responsible for the guiding the movement of chromosomes during mitosis and meiosis.
Answer:
1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.
