2. Consider a well-trained 130-pound female marathon runner, Jordan. Jordan has just loaded up on a carbohydrate meal and has the maximum amount of stored glycogen (6.8 grams of glycogen per pound of body weight). (10pts)
a. How many grams of glycogen is Jordan storing in her body? Show your calculations.

b. How many Calories does she have stored as glycogen?

c. If this same number of Calories were stored as fat, how much would it weigh?

d. Given your answers to a. and c., why do you think your body stores most of its extra energy as fat rather than glycogen?

e. Jordan will be competing in a marathon (26.2 miles). Given her above glycogen stores and the rate at which she consumes them running at marathon pace, she only has enough glycogen to last for 24 miles. What must she do in order to be able to run at the same pace beyond this?

Answers

Answer 1

Considering a well-trained 130-pound female marathon runner named Jordan.

The grams of glycogen Jordan is storing in her body is 884 grams.

Given that:

weight of the female marathon runner = 130 poundsmass of the glycogen = 6.8 grams / pound

a.

The total mass of glycogen that Jordan is storing in the body of 130 pounds is:

= 130 pounds × 6.8 grams/pound= 884 grams

b. The amount of Calories she has stored in the body of 130 pounds is calculated as follows.

Since 1 gram is equivalent to 7.716179 kcal

884 grams will be = (884 grams × 7.716179 kcal)/ 1 gram= 6821.102 kcal.

c.

Fat is a class of food that the when consumed provides energy to the body. It is usually stored as fatty acid and is measured in pounds.

One pound of fat usually requires an energy of about 3500 calories to burn.

Since 1 pound of fat requires 3500 calories;

The weight of the glycogen in fat will be:

= (6821.102 kcal × 1 pound of fat)/3500 kcal= 1.949 pounds of fat

d.

The body stores most of its extra energy as fat rather than glycogen because the body after 8 hours of eating, body starvation starts to occur. At this stage, the stored fat is designated to supply energy to the body.

e.

Given that:

Jordan will be competing in a marathon of = 26.2 milesFrom her condition, she has enough glycogen to last for 24 miles.

In order for her to be able to run at the same pace beyond the 24 miles, she needs to consume fatty food substances that can help her store additional fat that can be used to provide energy during the marathon race.

Therefore, we can conclude that we have understood the grams of glycogen that Jordan can store in her body, the conversion from grams to calories, and how Jordan can achieve the marathon of 26.2 miles.

how is the law of mendelian inheritance violated in down's syndrome

Answers

Answer:

According to the Law of segregation presented by Mendel, each gamete receives just one copy of every allele randomly. Normally all the cells follow the Mendelian inheritance.

In Down's syndrome, an individual gets 3 copies of a chromosome instead of the normal chromosome pair. This is also known as trisomy 21. It does not follow the law of segregation of Mendelian inheritance as it gets three instead of two.


In the southeastern United States, there is a small type of lizard called a fence lizard. They have short legs and live under leaves and dead logs.
Over the last 70 years, fire ants have moved into the lizard's environment. When fire ants sting the lizards on their body, the lizards can die
Scientists have observed that in places with fire ants and lizards living together for a long time, the lizards have longer legs. In places where fire
ants have only been there a short time, the lizards' legs are shorter overall
Fire ants move into a new environment with the lizards. What will most likely happen to the lizard population over the next several years?
A. Some of the lizards would try to develop new traits to avoid the ants, and they would pass on those traits to their

Explanation:

Speed is equal to distance/time. Since we know that the distance is 240m and the time taken to travel 240m was 12 seconds, we can divide them 240/12 and once we do this we can get our final answer of 20m/s.

Which statement describes the general relationship between the temperature and the absolute brightness of main sequence stars?

As temperature increases, absolute brightness remains the same.

Answers

Answer:

As temperature increases, absolute brightness increases

Explanation:

As temperature increases, absolute brightness increases

As temperature increases, absolute brightness increases. Therefore, option (C) is correct.

What is absolute brightness?

Absolute brightness, also known as absolute magnitude, is a measure of the intrinsic luminosity of a star, which is its total energy output per unit of time. Absolute brightness is defined as the brightness a star would have if it were placed at a standard distance of 10 parsecs (32.6 light years) from Earth. This standard distance allows astronomers to compare the luminosity of stars with different distances from Earth.

Absolute brightness is an important measure for astronomers because it helps them determine the true luminosity and size of a star. It also helps astronomers classify stars based on their luminosity and temperature, which is related to their evolutionary stage. For example, main sequence stars, which are stars in the process of burning hydrogen to helium, are classified based on their temperature and absolute brightness

C. Inserting genes from one plant into another
D. Returning bred plants to their natural habitat

Answers

Answer:

b

Explanation:

they chose the best tomatoes to make even better ones

Breeding tomatoes to increase fruit size is an example of selective breeding. Therefore option A is correct.

Selective breeding, also known as artificial selection, involves the intentional breeding of plants or animals to promote desired traits. The process typically involves selecting individuals with specific characteristics and breeding them to pass on those traits to the next generation.

In the given options, breeding tomatoes to increase fruit size is an example of selective breeding. By carefully selecting tomato plants with larger fruits and allowing them to reproduce, breeders can gradually enhance the fruit size of future generations.

This process relies on natural genetic variation within the tomato population and human intervention to guide the breeding process toward the desired outcome.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?

Answers

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.

Which of these events can lead to an increase in the population size of mice?
a. Some mice emigrate (leave) in search of food
b. Cats, owls, and snakes are added
c. More mice are born than die
d. A large number of mice die because of a forest fire
e. Cheese shortage

Answers

Answer: C) More mice are born than die

This means the birth rate would exceed the death rate, to make a positive growth rate in the population. So overall, the population will go up if more mice are born compared to those that die off.

Choices A, B, D and E all describe factors that would either kill mice or push them out of the habitat. Either way, these answer choices would have a decrease in population rather than increase. So we can eliminate these answer choices.

What is Fertilization in plants?

Fertilization is defined as the process of sexual reproduction, which occurs after pollination and germination which can be defined as the fusion of male gametes called pollen with female gametes called as ovum to form diploid zygote. It is a physio-chemical process that occurs after pollination of the carpel.

Steps of Fertilization occur in Plants

1. Pollination

2. Germination

3. Fertilization

Fertilization occurs through the pollen tube opening into the ovule through the micropyle and bursting into the embryo sac where the male nucleus fuses with an egg nucleus inside the ovule to form a diploid zygote, which then swells and develops into a fruit. These plants are similar in appearance when grown from seed but with the tuber method they will appear identical but not with the mother.

Thus, they will look the same because the plants grown from seeds are genetically identical to one another but not to the mother plant. So, the correct option is (A).
