The composition of the secretions of the eccrine glands is ________.
A) primarily uric acid
B) 99% water, sodium chloride, trace amounts of wastes, and vitamin C
C) fatty substances, proteins, antibodies, and trace amounts of minerals and vitamins
D) metabolic wastes
Answer:
B) 99% water, sodium chloride, trace amounts of wastes, and vitamin C
Explanation:
Eccrine glands are the major sweat glands of the human body, they are usually located virtually on all skin, but more profoundly found in palm and soles, Eccrine glands are energetic and actively participating in heat regulation by cooling the body, thereby evaporating water through secretion of sweat (which it major components are: 99% water, sodium chloride, trace amounts of wastes, and vitamin C
) on body surfaces and emotional induced sweating such as fear,pain,stress etc. Most especially, the glands on palms and soles do not respond to temperature but secrete at times of emotional stress.
Id say C. It makes the most sense to me.
Answer:
in the atmosphere
Explanation:
Carbon is also found in the atmosphere where it's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.
Answer:
C. 5.45 × 10^3 kg
Explanation:
Scientific notation is a way of writing large or small numbers in a decimal form also called exponential form i.e. expressed in terms of power of tens.
This simple method can ve followed when converting a number to scientific notation. We say; a × 10^x
a is the decimal number expressed in the power of tens
x is power of ten
According to the question, a male African elephant weighs 5450 kg.
To convert 5450 to scientific notation, we first of all move the decimal points to the left until we have only one number leftward
N.B: the decision point in any whole number is in front of the last number going rightwards.
We have, 5450 = 5.450
Next, we count how many times the decimal point was moved leftwards. In this case, it was moved three (3) times. Hence, the power of ten (x) is 3.
Because we moved leftwards, the power of ten will be a positive number. We have;
5.450 × 10^3 kg.
<u><em>WHAT HAPPENS TO OUR BODIES WHEN WE EXERCISE?</em></u>
<u><em /></u>
What is happening to her circulatory system?
When you exercise, or play football in this case, you are working your muscles and certain places in the body. When this happens, your muscles respire (burn the <u>FOOD</u> to produce <u>ENERGY</u>) more faster than they would normally, so the demand for <u>OXYGEN</u> and <u>GLUCOSE</u> is increased.
As the muscles are performing cellular <u>RESPIRATION</u> quicker than the norm, they need oxygen and glucose to reach them faster (glucose and oxygen are the components for cellular respiration), and also they need to get rid of their <u>CO2</u><u> </u>(products of cellular respiration are <u>CARBON DIOXIDE</u> and <u>WATER</u>) so the <u>HEART</u> is now pumping blood around the body at a faster rate in order to provide these cells with what they need. To summarize, the circulatory system has to work harder and faster during exercise to provide the cells at work with glucose and oxygen and to get rid of the waste carbon dioxide.
What is happening to her breathing system?
<em>{Relates to explanation given} </em>The requirement for oxygen is increased so now the respiratory system (in particular the <u>LUNGS</u>) have to work harder and faster to take in more oxygen and to exhale more <u>CO2</u>, thus you begin to breathe faster. To summarize, oxygen is inhaled quicker and carbon dioxide is exhaled quicker, therefore the rate of <u>DIFFUSION</u> is increased.
Diagram:
Draw picture of a girl playing football and then in the nest picture of her lungs and heart, you can also include arteries and the veins. Show how the lung and the heart work more harder during the exercise or when playing any sports
