B. Using Crayons To Color Is Using Fossil Fuels.
I believe that the mystery organism is most likely a plant and not an alga if it is surrounded by a cuticle. Thus the answer is B.
Alga and plats are similar in that they can produce their won food from nutrients and sunlight by a process called photosynthesis. The main difference is in their complexity, such that algae are simple organisms, sometimes unicellular, and even the largest types are relatively simple in structure. Green algae does not contain cuticle.
Answer: The blue colour of a biuret solution changes to violet.
Explanation: Biuret solution is a reagent that is used to test for the presence of protein in a substance.
A Biuret solution is composed of sodium hydroxide and copper II sulphate. Copper ions give the reagent its characteristic blue colour. Copper ions react with peptide bonds in the protein in an alkaline solution to form a Biuret compound with a violet colour. The copper ions which have two positive charges are reduced to a positive charge, thereby causing a colour change.
<span>Atmosphere is the system that includes oxygen, nitrogen, and ozone. The correct answer is C. All of these elements can be found in the air, which is a part of the atmosphere, which is why C is the correct answer. They are not found in the soil (geosphere), nor water (hydrosphere), not the living world (biosphere).Hope this helps. Let me know if you need additional help!</span><span />
Answer:

Explanation:
This question involves two distinct genes; one coding for seed shape and the other for seed colour. The allele for you seeds (R) is dominant over the allele for wrinkled seeds (r) in the first gene while the allele for yellow seeds (Y) is dominant over allele for green seeds (y).
In a cross involving RRYY (homozygous dominant for both traits) and RrYy (heterozygous for both genes), the following allelic combinations of gametes will be produced:
RRYY- RY, RY, RY, RY
RrYy- RY, Ry, rY, ry
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. The genotypes of the offsprings in the ratio 1:1:1:1 will be:
RRYY (4)
RRYy (4)
RrYY (4)
RrYy (4)
According to the question, offspring that have wrinkled seeds and yellow seed color will have genotype: rrYY or rrYy.
This genotype is not one of those that will be produced by the cross between a RRYY and RrYy parent. Hence, the probability of having an offspring with wrinkled seeds and yellow seed color is 0%
