The 10% rule means that when energy is passed in an ecosystem from one trophic level to the next, only 10% of the energy will be passed on.
Answer:
C. Fi 1:0, F2 3:1
Explanation:
Firstly, Mendel's law of segregation states that the alleles of a gene will randomly separate into gametes during gamete formation. In this case involving a single trait, hence, a single gene. Mendel crossed two purebreeding plants i.e. homozygous plants that produced different phenotypes for the same gene. He obtained his offsprings which he called F1 offsprings. He realized that all the F1 offsprings expressed only one phenotype. For example, when he crossed homozygous tall (TT) and short (tt) plants, he got F1 offsprings that were all tall.
He then self-crossed these F1 offsprings to produce a F2 offsprings that had a phenotypic ratio of 3:1 i.e. 3tall, 1short plant. He concluded that the alleles of the single gene had segregated into the gametes but one allele was capable of masking the expression of another, as seen in the heterozygous F1 offsprings that were all tall (Tt).
Hence, he obtained a 1:O ratio for his F1 offsprings then a 3:1 ratio for his F2 offsprings.
More than 90 percent of the weight of fat in foods and more than 95 percent of the stored fat in the human body are in the form of: triglycerides.

What is triglycerides?</h3>
Among fats, triglycerides are one. They make up the majority of the fat in your body. They originate in food, particularly in the butter, oils, and other fats you consume. Additionally, extra calories provide triglycerides. You consume these calories, which your body does not immediately require. These extra calories are converted by your body into triglycerides and stored as fat. The triglycerides are released when your body requires energy. The triglycerides are transported to your tissues by VLDL cholesterol particles.
Your chance of developing heart conditions like coronary artery disease is increased if your triglyceride levels are high.

Answer:
Option E
Explanation:
The flukes also called flatworms or platyhelminthes have a false body cavity or pseudocoelum which exist as patches between the body wall and the intestine, they do not originated mainly from the mesoderm like the true body cavity.
