Suppose that tomatoes with the RR genotype are red and those with rr are green. Assuming that this reflects conventional genetic
s shorthand of upper- and lowercase letters, which situation is true? A. r is dominant to R, and Rr individuals are green.
B. R is dominant to r, and Rr individuals are red.
C. r is dominant to R, and Rr individuals are red.
D. R is dominant to r, and Rr individuals are green.
E. r is dominant to R, and Rr individuals are yellow
B. R is dominant to r, and Rr individuals are red.
Explanation:
In genetics the dominant allele is represented by the uppercase letter and the recessive allele is represented by the lower case letter. A dominant allele always shows its dominance over the recessive allele. So in heterozygous condition dominant allele will reflects itself in the phenotype.
Here allele of red color allele is in capital letter and alleles of green color are shown in lower case which means R allele is the dominant allele and r is the recessive allele. Therefore R is dominant to r and in homozygous condition(Rr) red individual will be formed. So the right answer is B.
An empty graduated cylinder has a mass of 34.90 g. The cylinder is filled to the 9.40 mL mark with a liquid. The mass the cylinder with liquid is found to be 47.99 g. What is the density of the liquid?
Energy flows in only one direction through an ecosystem
The Sun supports most of Earth's ecosystems
Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
The food energy created by producers is passed to consumers, scavengers, and decomposers
Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
Animals at the third level have only 10% as much available to them as those at the second level
it might make it crack and harden it will also make it chucky instead of soft grassy fertal soil it will have almost no vitimin for plants to grow or to stay healthly
