What? I don’t understand what you are asking.....
Answer:
Research meteorologists study atmospheric phenomena such as lightning. Atmospheric scientists study the weather and climate, and examine how those conditions affect human activity and the earth in general
Explanation:
Acidity in human sweat is an example of<u> </u><u>innate immunity</u>
Explanation:
Sweat arising from human skin is acidic in nature with a pH ranging between 4.5 to 7.
As part of innate immunity, the skin acts both as a physical barrier and chemical shield.
As part of chemical shield, the skin’s sebaceous glands present on the skin produces an oily substance called sebum which contains free fatty acids. Further, hair follicles on skin releases lactic acid which bind with the amino acids of the proteins present on the keratinized layers of skin. The acidity of the sweat is due to the combined action of free fatty acids, lactic acid and the amino acids present on the skin.
This natural acidic nature of skin creates a hostile acidic environment to pathogens which prevents their entry into the body.
Preventing wind erosion in a dry, sandy area is feasible through any of the following land-use practices:
a. Tillage - creates soil roughness by making furrows and ridges that are perpendicular to the direction of the wind.
b. Crop rotation - rotations of legumes followed by shrubs followed by trees then back to legumes work best.
c. Intercropping - is the most widely used particularly in countries with desert areas. One of the most popularly used is oasis agriculture that makes use of about 3 layers of vegetation.
Answer:
No ATP is available to release attached actin and myosin molecules.
Explanation:
Two to six hours later after death, all skeletal muscles of the body become rigid and stiff. This situation is defined as Rigor mortis. It occurs from the lack of ATP along with the production of lactic acid. When breathing stopped permanently in the body, oxygen level also reduced; that’s why body muscles cannot go for any aerobic respiration to produce any ATP.
As we know already, during every muscle construction, ATP needs to break the cross-bridge between Myosin and Actin. So if there is no ATP produced in the body, separation of Myosin molecules from Actin molecules cannot happen anymore. This situation leads for rigor mortis.
