3. Phosphorus represents only 1% of human body weight. However, it is a buildingblock of very important macromolecules. Describe some of the cellular functions
that would not be possible without phosphorus.

Answers

Answer 1
Answer:

Answer:

It would be impossible to store and transfer genetic information

It would be impossible to carry out majority of cellular activities due to lack of usable energy.

Explanation:

Phosphorus, as stated in the question, represents a very low amount in our body system, however, its role in living systems cannot be underestimated. Phosphorus is a vital component of major biomolecules in our system.

- It is the building block of the NUCLEOTIDES that make up nucleic acids. Nucleic acids (DNA and RNA) store genetic information and help transfer it to offsprings. However, without one of the elemental components (phosphorus) that make up its structure, it will not be produced. Hence, the storage and transfer of genetic information will be impossible.

- Phosphorus also makes up the structure of the ADENOSINE TRIPHOSPHATE (ATP) molecule. ATP provides the cell with all the energy used in carrying out cellular functions. However, the absence of phosphorus needed for the synthesis of ATP, ATP will not be produced and ultimately no energy.

Answer 2
Answer:

Final answer:

Phosphorus is necessary for DNA, RNA, ATP, phospholipids, enzyme activation, energy metabolism, and pH balance in cells.

Explanation:

Phosphorus is an essential element in the human body and plays a crucial role in various cellular functions. One of the primary functions of phosphorus is its role in the structure and function of DNA, RNA, and ATP (adenosine triphosphate), which are all fundamental to cellular processes. Phosphorus is also involved in the formation of phospholipids, which are the main components of cell membranes.

Furthermore, phosphorus is important for the activation of enzymes, regulation of cellular energy metabolism, and maintaining pH balance within cells. The (ATP) molecule's structure is made up of phosphorus as well. All of the energy required for the cell to perform its cellular processes is provided by ATP. However, because phosphorus is required for the synthesis of ATP, ATP cannot be created, which results in the absence of energy.

What percent of human pathogens are zoonotic?a) 48%
b) 36%
c) 66%
d) 58%
e) 24%

Answers

Answer:

Option C, 66%

Explanation:

Zoonotic pathogens are the ones which are transmitted from animals to human beings.

As per the study of world health organisation, nearly 61% of human diseases caused by pathogens are due to Zoonotic pathogens. This percentage has increased from last ten decades to 75%.

As per Center for Disease Control and prevention, more than 50% pathogens are Zoonotic pathogens

These pathogens can enter human being through various medium such as air, water, contaminated food, hand or mouth contact etc.

Some common examples of disease caused by zoonotic pathogens are -

Malaria, dengu, Typhoid etc.

Hence, option C is correct

However, had it been a real sound, the sound's pitch would have been increased by the Doppler Effect, since the Falcon was moving _____ the source of the sound.

Answers

Answer:

Towards the southern of the sound

Explanation:

As the motion of the source of sound is moving,the percieved sound frequency varies .this is known as Doppler effect.the sound waves emited by the sources tends to bunch up in front of the source and spread out behind the source.

Since the falcon is moving towards the sound,the frequency increases and so does the pitch of the sound

Absorption is the process of transferring digested food from intestinal membranes into the blood circulation, which takes most nutrients straight to the _______ for further processing and/or storage. A. intestines  
 B. spleen   
C. pancreas   
D. liver

Answers

Absorption is the process of transferring digested food from intestinal membranes into the blood circulation, which takes most nutrients straight to the liver for further processing and/or storage. That is option D.

What is liver?

Liver is one of the largest visceral organs of the body that helps in the metabolism of nutrients.

After the ingestion of food, absorption takes place which is the process of transferring digested food from intestinal membranes into the blood circulation.

The nutrients must pass straight to the liver for metabolism.
