A cross involving true-breeding, red snapdragons and true-breeding, white snapdragons produce all pink offspring because both genes are present, neither being_____ over the other resulting in the____ of the trait.

Answers

Answer 1
Answer:

Answer: The correct answer for the blanks are- 1) Dominant and 2) Blending of the trait.

Incomplete dominance produces a blend/ intermediate phenotype of both the parental phenotypes ( such as Pink snapdragon here) because none of the parental allele completely masks the effect of other.

As per the given information in the question, when true-breeding, red snapdragons are crossed with true-breeding white snapdragons, they produce pink colored offspring. This means that neither of the parental gene is dominant over the other.

When both are cross bred, they will represent a heterozygous state ( when alleles for both the snapdragons are present ), and they will produce an intermediate phenotype ( that is a blend of both the traits). This represents blending of the parental trait.

dominant and blended

Why are decomposers essential to the continuation of life on Earth? How do they help the producers? How do they help the consumers? (Hint: They do NOT simply get rid of dead things)

Answers

Decomposers are essential to balancing of ecosystem. They not only decompose dead organic matter and waste from the environment but also extract essential nutrients such as nitrogen and carbon from the waste into the soil.  

The soil enriched in these nutrients serve as a source of nutrition for producers (trees, plants etc.) due to which they are able to produce food for primary consumers (which are mostly vegetarian), the primary consumers are then fed upon by the secondary and tertiary consumers which eventually die and are acted upon by decomposers to convert the useful nutrient with in the dead waste of organism into useful nutrients.

Decomposers are thus very important in completing the nutrient and energy cycle and release both nutrient and energy in the environment for reuse by the producers.

Answer:

Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

The % DV (percent Daily Value) is based on an average 2,000-calorie diet. One gram of carbohydrate provides 4 calories of energy. If Anna’s doctor recommends getting 60% of her calories from carbohydrates, how many grams of carbohydrates should she consume each day?

Answers

Answer: 300 grams

If Anna’s doctor recommends getting 60% of her calories from carbohydrates, it means that (2000*.60) or 1200 calories should come from carbohydrates.

If one gram of carbohydrate provides 4 calories of energy, then 1200 calories is equal to (1200/4) or 300 grams of carbohydrates Anna should consume each day.

Answer:

300 grams

Explanation:

you have to divide 2,000 by 60%

Answers

A series of complexes from electron donors to acceptors happen in an electron transport chain.  Due to the pumping action in the chain, protons result to having a high concentration in the intermembrane space yet a low concentration in the mitochondrial matrix.
