<u>Answer:</u>

The correct answer option is B. Green wavelengths are the least used in photosynthesis.

<u>Explanation:</u>

Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.

From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.

Therefore, this reflection of green light makes the leaves to appear green.

Q6.7. During many epidemics, health-care professionals emphasize the importance of
Serga [27]

During many epidemics, <u>healthcare </u>professionals emphasize the importance of  community mitigation strategies, such as wearing masks, frequent hand-washing, and social  distancing because these strategies help <u>reduce </u><u>transmission </u><u>even when drug-based treatments and vaccines are  unavailable.</u>

It is of <u>vital </u>importance in cases of epidemics to implement strategies such as:

  • Hand-washing
  • Wearing masks
  • Social distancing

in order to better protect our communities and ourselves.

Frequent hand-washing serves to<u> eliminate the presence of a </u><u>pathogen</u> <u>from the surface of your hands</u>, reducing the risks that it will find entry into your organism or land on a surface with which others will come into contact. Should you or someone else contract the pathogen anyways, wearing a mask can help to reduce or deny the possibility of transmitting the disease.

Finally, should both previous measures fail, meaning that the virus or pathogen has infected an individual and penetrated the masks, social distancing can act as a <u>final barrier</u> that the pathogen will rarely be able to surpass, given that most pathogens <u>cannot remain airborne over large distances. </u>

For these reasons, healthcare professionals emphasize the importance of these strategies because they help reduce transmission <u>until vaccines or drug-based treatments become  available and </u><u>herd immunity </u><u>can be reached. </u>

Alja [10]

Answer:

The correct answer will be option-A

Explanation:

The practice of marriage is practised in every culture which is associated with the union of the boy and a girl to which they are committed to spending a life-long relationship.

The studies on the preferences shown by the woman who has to get married have to look for the boys who are career-oriented which could provide a good earning to feed them and their family and fond of children to establish a family which will help develop the stronger relationship between them.

The girls ignored the attractiveness feature of their spouses as in a long term relationship attractiveness does not matter because of the feeling of love and strong bond between them.

Thus, option-A is the correct answer.

When tissues are subjected to chemical or physical trauma or invasion by pathogenic microorganisms, what can occur?
777dan777 [17]

Answer:

Inflammation

Explanation:

Inflammation is an immune response produced in the body in response to the damage or trauma caused by physical or chemical factors.

The injured tissue can allow the entry of the microorganism in the body which could cause disease therefore the immune response gets activated to eliminate the pathogen.

The inflammation is marked by the swelling and redness in the injured portion due to the increased flow of blood carrying the White blood cells in that area. The immune cells interact with the pathogen and kill the pathogen.

Thus, Inflammation is the correct answer.
