In what way can the human circulatory system be described as double circulation?.
Answer:
Explanation:
The human circulatory system has three key components: blood vessels, blood, and the heart. It is called a double circulatory system because blood passes through the heart twice per circuit.
The right pump sends deoxygenated blood to the lungs where it becomes oxygenated and returns to the heart.
The left pump sends the newly oxygenated blood around the body. When this blood returns to the heart, it has returned to a deoxygenated state.
Blood Passes Through The Heart Twice Per Circuit
Blood enters the heart:
Deoxygenated blood from the body enters the right atrium of the heart.
Blood pumped to lungs:
The right ventricle pumps this deoxygenated blood out of the heart and towards the lungs.
Lungs oxygenate the blood:
In the lungs, the deoxygenated blood exchanges carbon dioxide for oxygen. This is how it becomes oxygenated (contains oxygen).
Blood returns to the heart:
Oxygenated blood returns to the left atrium of the heart.
Blood pumped into the body:
This oxygenated blood is pumped out of the heart and to the body by the left ventricle.
Blood returns to the heart:
The oxygenated blood gives its oxygen to body cells in exchange for carbon dioxide. The blood becomes deoxygenated and returns to the heart.
the method for determining energy expenditure in which the amount of oxygen a person uses is measured is called
Answer:
In indirect calorimetry, energy expenditure is determined by measuring the amount of oxygen consumed and carbon dioxide produced.

Toxins, such as many pesticides, do not necessarily stay isolated to the area where they are intended to be placed because they can be washed by underground water.
What are pesticides?Pesticides are chemical substances used to eliminate insects and other pests from the Earth's surface.
Pesticides can have a systemic effect, which also means that they do not stay in a specific location.
In conclusion, toxins, such as many pesticides, do not necessarily stay isolated to the area where they are intended to be placed because they can be washed by underground water.

Explain the properties of RNA
Answer:
RNA forms in the nucleolus, and then moves to specialized regions of the cytoplasm depending on the type of RNA formed.
RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions. RNA’s larger helical grooves mean it is more easily subject to attack by enzymes.
RNA strands are continually made, broken down and reused.
RNA is more resistant to damage from UV light than DNA.
RNA’s mutation rate is relatively higher.
Unusual bases may be present.
The number of RNA may differ from cell to cell.
Rate of renaturation after melting is quick.
RNA is more versatile than DNA, capable of performing numerous, diverse tasks in an organism.
RNA or ribonucleic acid is a polymer of nucleotides which is made up of a ribose sugar, a phosphate, and bases such as adenine, guanine, cytosine, and uracil.
It is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes.
Explanation:
Answer: The full form of RNA is RIBONUCLEIC ACID and is present mostly in viruses. RNA contains genetic information just like DNA.

Which of the following is a data piece a demographer would NOT be interested in when studying demography
A. Fertility
B. Mortality
C. Jobs
D.Migration
Answer:
C. Jobs
Explanation:
Demography is usually defined as the science of vital and social statistics, as of births, deaths, diseases, marriages etc. of populations.
This means that a demographer study both birth and death rates as they focus on human characteristics.
In demography, fertility is the birthrate of a population. Or in other words, the ability to produce offspring in a population. Mortality is the opposite of fertility; the death rate of a population. Both of these things are something that a demographer would study as they relate to the continuation of human society. Migration though, is a demographic process in which people migrate between different locations or places, resulting in a contribution to a population. So to explain the demographic terms, international migration takes an impact on a population with its age and size structure resulting in an indirect influence on the rate of future births in a population. This means that a overall, fertility, mortality, and migration all are therefore things that a demographer would study. After using process of elimination between the options, there is one left over, which is:
Option C - Jobs
Suppose a hare spotted a coyote and tried to run away. Coyotes can run at a speed of 70 km/h. Hare's can run at a speed of 65 km/h. How far could the hare run before the coyote catches up? assume the hare is 25 m from the coyote
Answer: 0.35 km or 350 m
Explanation:
The coyote runs 70 km/h
The hare runs 65 km/h
The coyote is 5 km/h faster than the hare
The hare is 25 m away, 0.025 km
I will graph this. x is the time passed, y is the distance. The point of intersection is when the coyote catches up.
(0.005, 0.35)
-> The hare can run 0.35 km before the coyote catches up.

Explanation:
a thermometer with measurements divided into tenths is more ____ than a thermometer with measurements divided into whole numbers
Answer:
Accurate would be the answer I believe.
Explanation:
A thermometer would be more accurate in tenths because it can get much closer to the actual value of the temperature that is being read. Let's say someone has a temperature of 98.7 a thermometer that is in the tenths would be accurate and say that the temperature is 98.7, but if it was in whole numbers it would have to round the temperature, which would be inaccurate.
Accuracy: description of how close a measurement is to an accepted or true value.
Answer:
Accuracy would be the correct answer.
