Answer:
Although direct calorimetry is considered to be the most precise technique for the measurement of metabolic rate, construction of such a chamber that is large enough for doing exercise physiology research (or any research for that matter) is extremely expensive and not at all mobile.
Explanation:
Direct calorimetry measures the heat production of an individual, in calories, when placed in an insulated chamber where the heat is transferred to surrounding water. This is a very accurate method of measuring energy expenditure.
Answer:
Proportion of the F2 male with red eyes and forked bristle will be 1/4
Explanation:
forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal bristles (X+).
Brown eyes are caused by an allele (b) that is autosomal and recessive to an allele for red eyes (b+)
A female fly that is homozygous for normal bristles and red eyes mates with a male fly that has forked bristles and brown eyes
X+X+b+b+ x Xfbb
the F1 gives 1/2X+Xf 1/2b+b
1/2X+Y 1/2b+b
intercross of F1
Proportion of the F2 male with red eyes and forked bristle will be
forked bristle= Xfy = 1/2 and for red eyes 2/4= 1/2 = 1/2x1/2 =1/4
Glycogen provides long-term energy storage.
Glycogen is an example of a carbohydrate which is a polysaccharide that acts as a long-term energy storage compound in animals.
<h2>Further Explanation
</h2>
- Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
- Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.
Energy source in animals
- Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
- These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
- When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
- Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.
Energy source in plants
- In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.
<em><u>Why other Choices are incorrect</u></em>:
<h3>Glucagon </h3>
- Glucagon is the hormone that increases the blood glucose level to avoid it from dropping below optimum level.
- The hormone acts on the liver to stimulate the breakdown of glycogen to glucose, a process called glycogenolysis, and the glucose is released to the blood stream.
<h3>
Glucose
</h3>
- Glucose is a simple carbohydrate classified as monosaccharides. It acts as the short term source of energy in both plants and animals.
- It is readily broken down during the process of cellular respiration to yield energy in the form of ATP, which is then used to drive cellular processes.
<h3>Cellulose
</h3>
- Cellulose is an example of a complex carbohydrates known as polysaccharides.
- It is found in plants cells lining the cell wall of all plant cells which is one of the key distinguishing feature between plant cells and animal cells.

Answer: A (ATP only)
Explanation:
Both NADH and pyruvate are energy store. NADH and pyruvate can not directly be used to drive biological reaction.The metabolism of pyruvate releases energy in the form of ATP. NADH produces ATP through the electron transport chain (ETC). Adenosine Triphosphate (ATP) is referred to as the energy currency of the cell. ATP is used directly as energy to drive endergonic and exergonic biological reaction.
Answer is ATP only
The question is incomplete, however, the missing part is given as below:
A. Yeast cells and sugar are placed in the solution. B. Water plants in the solution are placed under a bright lamp. C. Algae are placed in the solution and left in a dark room. D. A person blows air into the solution through a straw.
Answer:
The correct answer is - B. Water plants in the solution are placed under a bright lamp.
Explanation:
As we know adding carbon dioxide in as solution result in the change of its acidity this is the result in the indicator to change from blue to yellow. In the question, it is asked that what factors from the given option will cause yellow indictor to blue which means what factors cause the solution to be alkaline from acidic.
Placing the green water plants in the solution under a bright lamp will cause the is utilizing and remove present carbon dioxide in the solution and leads the to blue color from the yellow color of the solution.
