How is the water and boiling point of water useful to us
Answer:
The boiling point of water can be used to illustrate the importance of hydrogen bonds in living systems. The boiling point of a compound is the temperature at which a liquid becomes a gas. When the temperature is high enough to separate the individual molecules from each other, they boil, or become a gas.

What are the chances that the parents will have a hairless baby guinea pig?
A. 75%
B. 25%
Answer:
I believe it is B
Explanation:
hope this helps
Answer:
B. 25%
Explanation:
There is a 50-75% or about half chance that the babies bred by a Skinny Pig and a haired Skinny pig gene carrier, will have hairless Skinny pig babies. The rest of the babies will just be skinny pig gene carriers. There is only a 25% chance that 1 or so hairless skinny babies will be born in these litters.
a increase in breathing rate can be triggered by an increase in the carbon dioxide containing in the blood. the increase in breathing rate is caused by a mechanism called
when there is high concentration of co2 in our body then respiratory centre ( medulla and pons) get activated and it increase rate of respiration which decreases co2 concentration
The apneustic (stimulating) and pnuemotaxic (limiting) centers of the pons work together to control rate of breathing.
What is medulla?Medulla is defined as the lowest part of the brain and the lowest portion of the brainstem. The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
The medulla sends signals to the muscles that initiate inspiration and expiration and controls nonrespiratory air movement reflexes, like coughing and sneezing.

What ideas were changing in the scientific community at the time of Darwin's travels? How might those new ideas influenced Darwin?
Answer and Explanation:
At the time of Darwin's travels, the scientific community was beginning to abandon ideas linked to creationism to adopt more scientific and testable concepts, less linked to religiosity. Darwin was very influenced by these new concepts and decided to study a way to apply them to the biological diversity that planet earth presented. He wanted to explain this diversity through scientific data, obtained by experiments and logical reasoning, without the interference of creationist concepts and that would show how life on earth changes over the years and how species of living beings were created. This was one of the kicks that made him start his travels and his studies on biological evolution.

Lamarck's ideas on evolution were adopted by some Russian scientists, includingLysenko. Russian textbooks printed Lysenko's assertionthat workmen who develop strong muscles from working in the mines would produce children who would be born stronger. Which of the major elements of evolution by natural selection is violated by this assertion
Answer:
The acquired characteristics are inherited.
Explanation:
Lamarck was a French naturalist and biologist. Lamarck was considered to be the early proponent who occurred the biological evolution. He was will known all over the world as early evolutionists.
Lamarck believed that the living things grow directly in the upward direction from a simple to a more complex form.
In the context, the ideas on the evolution were adopted by the Russian scientist which includes Lysenko. The Russian textbooks printed the assertion of Lysenko assertion that workmen develops a strong muscles those who are working in the mines that would produce strong children.
Bu this assertion, it violated the acquired characteristics that are inherited.
How do antibodies fight pathogens
Answer:
1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization).
2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall).
One reason why anabolic steroids can imitate the hormone testosterone is because
(1) anabolic steroids and testosterone both interact with the same cell receptors
(2) testosterone acts only on muscle cells
(3) females produce small amounts of the hormone testosterone
(4) an increase in testosterone in males using anabolic steroids increases male features
Answer:it’s 4 (an increase in testosterone in males unsung anabolic steroids increases male features
Explanation:
Anabolic steroids can imitate the hormone testosterone is because they both interact with the same cell receptors.
What do you mean by anabolic steroids?"Anabolic steroids are synthetic (man-made) versions of testosterone."It is used to enhance physical appearance by increasing muscle mass and decreasing fat.What is testosterone?"Testosterone is the male s ex hormone that is made in the testicles."It helps in regulating male s exual development and functions.What are cell receptors?"Structures found in the plasma membrane (surface) of cells that tightly bind specific molecules."It functions in information transmission.The anabolic steroids interact with same cells receptors as that of testosterone and results in increase of testosterone level causing increase in muscle mass.
Hence, the correct option is 1. anabolic steroids and testosterone both interact with the same cell receptors.

why is studying climate change a scientific challenge? ( please be specific and
go into depth)
Answer:
Climate change is already happening: temperatures are rising, drought and wildfires are starting to occur more frequently, rainfall patterns are shifting, glaciers and snow are melting and the global mean sea level is rising. These ever-changing trends mean that scientists have to be well acquainted with all this which requires a great deal of understanding and patience.
The political interests in research often limit the results and many a time misleading
Data for climate research is in many instances difficult to access, often at a price, and according to the source and type of data, the formats for retrieval can be very different. In addition, data may not be available for the same time and space scales. There is often an incompatibility between socio-economic and physical data, both necessary for climate modeling efforts because data collection is generally carried out by different agencies for different purposes. This means scientists have to analyze this data as useful and then research on it.

The use of coal to generate electricity in a power plant can often appear to be the least expensive option, but only if the environmental impacts of burning coal are not accounted for. Select the option that best describes some of the environmental impacts of using coal for electricity generation A. Air pollution resulting from burning coal B. Erosion and water pollution from mining operations C. Both A and B are correct D. Neither A nor B are correct
Answer:
C. Both A and B are correct
Explanation:
Coal is one of the important fuel for the generation of electric energy in the steam generator. Coal is mined from the coal mines and is fed into the steam generator to produce steam that is used to generate electricity.
The mining of coal can affect the environment nearby as it destroys the forest cover or trees nearby. It leads to erosion and water pollution. Also the carbon emission from the burning of the coal releases harmful pollutants inn the atmosphere which causes air pollution.
Thus both options (A) and (B) are correct.

What prevents blood from circulating backward in veins?
A.valves
B. capillaries
C. lungs
D. heart
Answer:
A.Valves
Explanation:
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.
