The correct answer is -

O2 - through the stomata

Glucose - through the phloem in the veins

H2O- through stomata

Explanation:

In the process of photosynthesis, plants capture light energy to initiate a chemical reaction that uses CO2 and H2O as reactants and converted them into oxygen and sugar or glucose as products. Thus, oxygen and glucose are the products form in photosynthesis.

These products are carried through various paths to the new location to get utilized. Glucose is carried by the phloem in the veins out to the plant whereas oxygen and water diffuse into the environment through stomata.

A gallon of olive oil sitting on a high shelf is likely to have:
a. Kinetic Energy
b. Gravitational Potential Energy
c. Electrical Energy
d. Nuclear Energy

Answers

B. Because it has potential energy and it’s not kinetic energy because that’s what it would have if that container fell.

Answer:

b. Gravitational Potential Energy

Explanation:

The olive oil currently holds potential energy, which it is given from the pull of gravity, constantly pulling it down to the earth.

If the olive oil were knocked down the gravitational energy would then be kinetic, or moving. The other choice simply don’t make sense, as the olive oil is unlikely to be electrically charged, nuclear reactive, or -as it’s not currently moving- have kinetic energy. Therefore the proper response is:

b. Gravitational Potential Energy

b. Blood glucose increases to normal.
c. Liver breaks down glycogen and releases glucose to the blood.
d. Liver takes up glucose and stores it as glycogen.
e. Pancreas releases glucagon.
f. Body cells take up more glucose.

Answers

Answer:

c. Liver breaks down glycogen and releases glucose to the blood.

Explanation:

Living system can be defined as the internal systems found in living organisms and how various materials are circulated inside organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.

Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.

A liver refers to a large, essential organ that is reddish-brown in color which is used to synthesize proteins, secrete bile, and the detoxification of metabolites.

Glycogenolysis can be defined as a process which typically involves the breaking down of the primary carbohydrates (glycogen) present in liver into glucose so as to maintain blood glucose rates and provide necessary energy for living organisms.

Hence, the true statement is that liver breaks down glycogen and releases glucose to the blood.

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

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.

Answers

Answer:

If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.  

Explanation:

A=T
so A is 12% too
100-(12+12)
=100-24
=76
then divide by 2 to get each C and G
76/2=38
so C and G are each 38%

Answers

Answer:

6. Parasitism

9. mutualism

10. predation

7. predation

8. mutualism

Explanation:

Living organisms, in their natural habitat, forms certain relationships with one another. These relationships are as follows:

- Mutualism is the association of two organisms in which both organisms benefits from one another in the relationship. Example is butterfly and flower in this question, where the butterfly helps pollinate the flower while the plants provide food source for the butterfly. Another example is coral reefs and fishes where the fishes and coral depend on one another.

- Predation is the kind of relationship in which one living organism called PREDATOR kills and feeds on another called PREY. Examples are the relationship between birds and worms, lion and buffalo where the bird and lion are predators while worm and buffalo are preys.

- Parasitism is the relationship between two organisms in which one organism called PARASITE lives on and derive nourishments from another organism called HOST. In the example of aphid and rose plant where the aphid is the parasite and rose plant is the host.

The type of interaction that is being performed by the following pairs of

organisms include the following:

Aphid and rose plant - ParasitismButterflies and flowers - MutualismBirds and worms- PredationLion and buffalo - PredationCoral reefs and fishes - Mutualism

Aphid and rose plant have a parasitic relationship due to the aphids taking

up vital nutrients from the rose plant thereby resulting in distorted growth.

Butterflies and flowers have a mutualistic relationship as the butterfly aids

pollination of the flowers and also derives food and juice in return.

Birds and worms have a predatory relationship as the birds eat worms for

food and survival.

Lion and buffalo  have a predatory relationship as the Lions eat buffalos for

food and survival.

Coral reefs and fishes have a mutualistic relationship as the fishes aids

reproductive ability of the coral reefs while the fishes benefit food and habitat in return.

Answers

Answer:

1. Thyroid gland is the endocrine gland that is involved here.

2. TSH stimulation test did not show an increase in the output of thyroid hormones secreted from thyroid glands which makes it a primary disorder. The determination of TSH or TRH gives an idea about hypothyroidism if it is due to feedback inhibition of the pituitary or absence of TSH hormone from the pituitary, however, Circulating levels of TRH not necessary.

3.  The feedback loop involves the following:

TRH hormone secreted from the hypothalamus triggers the anterior pituitary to secret TSH that in turn triggers the relapsing of the T3 and T4 levels by the thyroid glands. If there is a low level of T3 and T4 hormones then negative feedback takes place and increases the TSH output.

4.  symptoms:

Not able to uptake the iodide into the cells of the thyroid gland

Defects in the conversion of iodide to iodine

tyrosine molecule iodization

secretion of the hormones from the Tg molecules

Less TSH receptors on the gland.
