Answer:
X: Producers undergo photosynthesis;
Y: Decomposers return carbon to the soil and release waste
Explanation:
Producers, for example, a clover, will take the CO2 in the atmosphere and use it in photosynthesis to turn it into nutrients, then the consumers, for example, a deer, will eat the producer to gain nutrients. After the consumer dies, the decomposer, for example, fungus, will eat away at the consumer, releasing CO2 into the atmosphere. Then the cycle keeps going.
Answer:
Typically two, because fat is a lipid and contains two monomers
Explanation:
Answer:
Phenotypic ratio = 1 Red : 1 Pink
Explanation:
This phenomenon exhited by the gene coding for flower colour in four o'clock plants is called INCOMPLETE DOMINANCE i.e. the red flower allele (R) is not completely dominant over the white flower allele (r), hence, a third intermediate pink phenotype (Rr) is formed in an heterozygous state. The red and white flowers will only be expressed in a RR and rr genotypes respectively.
In a cross between a red-flowered 4 o'clock plant (RR) and a pink-flowered 4 o'clock plant (Rr), the gametes:
R and R will be produced by the red-flowered plant while gamete R and r will be produced by the pink-flowered plant. Using this gamete in a punnet square, one will have four possible offsprings in which two will be phenotypically red-flowered (RR) and two phenotypically pink-flowered (Rr). i.e. 2RR:2Rr
Hence, the phenotypic ratio is 1:1 Red to Pink flower
