People have different skin colors mainly because their melanocytes produce different amount and kinds of melanin. The genetic mechanism behind human skin color is mainly regulated by the enzyme tyrosinase, which creates the color of the skin, eyes, and hair shades.

Which of the following statements about blood is false?

SCORPION-xisa [38]

Answer:

B) The normal pH of blood is 6.8 to 7.0.

Explanation:

The blood pH under normal health conditions is between 7.35 and 7.45. Below this range, blood pH is considered more acidic than normal, and it may indicate that the body is eliminating a lower amount of $CO{2}$ than normal, or that there is a decrease in the concentration of $HCO{3-}$ or accumulation of acid in the blood due to poisoning or disease.

Q6.7. During many epidemics, health-care professionals emphasize the importance of

Serga [27]

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

It is of vital 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 eliminate the presence of a pathogen from the surface of your hands, 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 final barrier that the pathogen will rarely be able to surpass, given that most pathogens cannot remain airborne over large distances.

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

Explain how the process of meiosis relates to the way in which a child

prisoha [69]

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. That means that they will never be a copy of their parents because of their different genetic material. Characteristics, such as eye color, hair type and color, the shapes of facial features, and height and build, and attribute the combinations of these to the portions of DNA inherited from each parent which makes them different but still carry the DNA of their parents.
