i'm unsure of your statement, but i believe that the statement is false. A rake would add more physical activity, since you're using both leg muscles while walking, and arm muscles.
Answer:
The correct answer would be B. 18 to 26%.
The muscle efficiency is calculated by dividing mechanical work output by total metabolic cost.
It is estimated that human muscles have an efficiency of about 18% to 26%.
The efficiency is low because most of the energy is lost when food energy is converted into ATP (adenosine triphophate).
In addition, there is second energy loss when energy in the form of ATP is converted into the mechanical energy such as rowing, cycling et cetera.
Explanation:
Answer:
The correct answer is herd immunity.
Explanation:
Herd immunity is the resistance against a contagious disease provided by the immune individuals which makes the major part of the population to few susceptible individuals in the community.
So as most of the population is immune to the disease therefore that disease is not able to overpass these immune individuals and the susceptible person is protected indirectly from that contagious disease. By vaccinating most of the people against a disease we can gain herd immunity. So the right answer is herd immunity.
No college majors or educational programs could be found in our database for this career. This typically means that post-secondary education is not required for this type of job.
1.) Exocrine gland is a gland that makes up substances such as tears, sweat, milk, and saliva, and then releases them through a opening to a body surface.
2.) Two types of exocrine glands found in the skin would be (eccrine sweat gland and sebaceous glands).
3.) When internal temperatures rise the sweat glands secrete water to the skins surface, where heat is being removed by evaporation.
4.) The main function of the sweat glands is to control body temperature.
5.) The secretion of the sebaceous glands is to produce and secrete sebum, a group of complex oils including fatty acid breakdown products, cholesterol, and wax esters. It’s purpose is to lubricate the skin to protect against friction and makes it more impervious to moisture.
