Difference between male and female respiratory system

1 answer:

8 0

Female lungs tend to be smaller and weigh less than those of males and, on average, may contain fewer respiratory bronchioles at birth. The number of alveoli per unit area and alveolar volume do not differ between male and females, but boys have larger lungs than girls. Thus, the total number of alveoli and alveolar surface area are larger for boys than girls of a given age.

What is the role of oxygen in photosynthesis and in cellular respiration?

scZoUnD [109]

Answer:

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process

Explanation:

product, whereas cellular respiration uses oxygen as a reactant to release energy from food

Pachacha [2.7K]

<h2>The correct answer is: Transcription.</h2>

Explanation:

Viruses do not possess any machinery necessary for the purpose of their reproduction.
They only possess their genetic material enclosed within a capsid structure.
The capsid is constituted of glycoproteins.
They completely depend upon the components and organelles of the host cells whom they infect to help them carry out their reproduction process.
After infecting a host cell, the viruses hijack all the machinery and components of the host cell and use them for the purpose of transcribing their genetic material (DNA or deoxyribonucleic acid) to produce the virus-specific mRNAs (messenger Ribonucleic Acid).
These mRNAs are further translated into virus-specific proteins using the host-specific Ribosomes. These virus-specific proteins are required for replicating the viral genetic material and producing the capsid structure.
The virus-specific proteins and glycoproteins are synthesized by utilizing the raw materials from the host cells.
Transcription is the process by which an enzyme called RNA polymerase or DNA dependent RNA polymerase copies the protein coding region of the DNA (gene) in the form of an RNA sequence (mRNA).
The synthesis of the mRNA happens in the 5' to 3' direction. This mRNA is further recognized and converted into the amino acid sequence with the help of the Ribosome.
The amino acid sequence folds to give rise to the protein.

labwork [276]

Answer:

b. active transport

Explanation:

Active transport -

It is the movement of the molecules across the membrane via a region of lower concentration towards the region of higher concentration , and in some cases , the flow is independent of the concentration .Its is known as active transport .

This process needs some amount of energy in the form of cellular energy .

Hence , the correct term for the given statement is active transport .

What are the products of light-dependent reactions? Why are they important in light-independent reactions?

tamaranim1 [39]

The products of light-dependent reaction are ATP and NADPH. They are essentially required to fix carbon dioxide and make glucose in light-independent reactions.

Light-dependent reactions are those that use the direct sunlight energy to make usable forms of chemical energy i.e., ATP and NADPH. For this, a pigment called chlorophyll is essential that has the ability to the capture the sunlight.

Light-independent reactions are those that do not directly depend on the sunlight energy to complete their process. Instead they are dependent on the products of light reactions so that they can fix atmospheric carbon dioxide and make glucose for the plant. Calvin cycle is the main process of light-independent reaction.
