The correct option is C.
Roundworm belongs to the kingdom animalia and to the phylum nematoda. It has round, unsegmented, smooth and thin body which can grow to the maximum of four feet in length. It has a bilateral symmetry. A roundworm has no skeleton and it reproduces sexually.
Answer:
Pleiotropy
Explanation:
Pleiotropy is a condition that occurs when one gene affect several other phenotypic traits that are not related. The autosomal dominant allele of the genetic disease called blue sclera, is pleiotropic. It has the potential of causing also fragile bones and deafness which are entirely unrelated traits. Genetic mutation of a gene is the most likely explainable reason for the connection of these traits together.
Answer:
here's your answer
Explanation:
the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.
Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves
Answer:
Dependent: Reduction
Independent: Solar Energy
Controlled: B
Explanation:
The dependent variable is what is being measured in the lab.
The independent variable is what is being CHANGED by the individual
The control is what is kept the SAME throughout the lab.
Hope this helped!
