Question 11
1 pts
A runner expends an average of 4 kcal per minute during a two hour run. She want to eat a meal of
50% energy from carbohydrate, 25% of energy from protein and 25% of energy from fat, how
much protein would their meal have to contain, in order to replenish their expended energy?

Answers

Answer 1

Given what we know about nutrition, we can confirm that the runner's meal would have to contain 30 grams of protein.

The runner in question wishes to complete a two-hour run while expending 4kcal or calories per minute, for a total of 480kcal. Furthermore, the runner wishes for only 25% (120kcal) of this energy to come from a source of protein.

Since every gram of protein adds 4 calories of energy to the meal, and we have to account for 120 calories, the runner will have to consume 30 grams of protein to achieve the desired results.

How does meiosis most benefit a species?
It decreases the number of chromosomes.
It increases genetic variation.
It increases the number of chromosomes.
It increases mutations.

Answers

Answer:

It increases genetic variation.

Explanation:

Meiosis does not decrease the number of chromosomes nor increase the number of them, it merely splits them.

While it could increase mutations, this might not necesarily be a good thing.

However, it does increase genetic variation, especially during the process where crossing over occurs. Increased genetic variation is beneficial for the population for many reasons like higher resistance to certain diseases. Increasing genetic variation also makes a species look unique from other members of the species.

John had unattached earlobes like his father, but his mother has attached earlobes. What is johns genotype with unattached being dominant

Answers

Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.

John's genotype with unattached being dominant is Aa.

Using A to represent the allelesSince his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa). So for John to have an unattached earlobe, his father has to be either AA or Aa. Therefore John's genotype would be Aa

What is the benefit of this complementary nature of DNA?
-It helps in controlling the amount of protein produced by the cells.
-It helps in storing all the information required for the cell to function efficiently.
-It helps in the synthesizing of two new identical DNA strands from each parent strand
-It helps in the unwinding of DNA allowing for the formation of chromosomes during mitosis

Answers

The complementary nature of DNA rule ensures that only some particular base pairing are allowed and the DNA strands are complementary to each other.

The benefit of this complementary nature of DNA is that it helps in the synthesizing of two new identical DNA strands from each parent strand.

In DNA replication, the complementary nature of DNA ensures that following the production of new identical DNA strands, the composition of the new strands produced is intact and identical in composition.

What are the two theories that are combined in the synthetic theory of evolution?

Answers

The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

Synthetic theory of Evolution

The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.

The theory explains that changes in the genes of organism are what causes the evolution of organism.

The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.

The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.

Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
