The Fitness of Water. For each of these statements about water, decide whether the statement is true and describes a property that makes water a desirable component of cells (T); is true but describes a property that has no bearing on water as a cellular constituent (X); or is false (F). For each true statement, indicate a possible benefit to living organisms.
a. Water is a polar molecule and hence an excellent solvent for polar compounds.
b. Water can be formed by the reduction of molecular oxygen O2.
c. The density of water is less thaan the density of ice.
d. The molecules of liquid water are extensively hydrogen-bonded to one another.
e. Water is odorless and tasteless.
f. Water has a high specific heat.
g. Water has a high heat of vaporization.
Answer:
A) True
The polarity of water is what makes it an ideal transport vehicle for nutrients and micronutrients that are water-soluble. Within organisms, water can be used to transport nutrients and even waste from one part of the body to the other. In the case of humans, urine is used to get rid of soluble waste from within the body.
B) True
During the process of photosynthesis, carbon dioxide (CO2) and water (H2O) are taken from the air and soil respectively. Oxygen is able to produce water when it is reduced. Hydrogen during this process is oxidized.
C) False
Ice floats on water. Hence it cannot be denser than water. Rather, water is denser than Ice. Because of the structure of hydrogen bonds, when they are iced, the bonds tend to pull apart, thus making ice expand somewhat. This expansion creates microscopic pockets of air in the molecules thus given them buoyancy.
D) True (X)
E) True (X)
F) True
Heat Capacity refers to the amount of heat a substance like water can absorb before it's temperature rises by 1 degree. This property is important, because, were it not for the high specific heat capacity of water, many people and plants would have boiled over.
G True (X)
Heat of vaporization is the kind and amount of energy required to alter one gram of liquid into a gas at boiling point

Biodiversity in the Amazon rainforest will most likely?
Answer:
In the future, the Amazon rainforest's biodiversity will decrease unless something is done about the mass destruction of habitats and deforestation at the rate of 40 football fields a minute. Biodiversity is the variation of organisms (plants, animals and bacteria) in the world or in a specific habitat.

2. A man has type A blood and his wife has type B blood. A physician types the blood of their four children
and finds that each of the children has a different blood type. What are the genotypes of the parents? How
would you explain that all four blood types could be represented by these four children?
Answer:
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens .

Which location has the warmer air temperature: Recife or Lima? Why?
Answer:
Recife has warmer air temperature because it is closer to the equator
Answer:Recife has the warmer air temperature
Explanation:Recife has the warmer air temperature.The first reason is that Recife,Brazil is closer to the equator than Lima,Peru which means Recife will receive more energy from the sun.Another reason is that the ocean currents that pass both locations have different origin.The current that passes Recife originated near the equator so that causes it to bring lots of energy causing the air temperature of Recife to be high and warm.The current that passes Lima originated near the South Pole so that causes it to bring less energy.Also Lima,Peru has upwelling as we see in the map and that also affects Lima,Peru to have colder air temperature

5.Write observation and conclusion of each of the following activities.
Answer:
Water puts pressure depends on their amount.
Explanation:
In the bottle, there is large quantity of water that put high pressure on the bag present at the side of the bottle that leads to swelling of the bag whereas, if the bag is present at the bottom not at the side and water is also present in large amount so more swelling of bag occurs so we can conclude that more water puts more pressure and less water puts less pressure.

A conservation ecologist is studying Pacific Green Sea Turtles. One population is based on a remote island in the Indo-pacific that has very little tourist or human activity. The other population is on the coast of Australia and deals with more consequences of human activity. The ecologist has taken counts of the number of eggs in each female’s nest at both locations to evaluate the reproductive success. Is there a statistically significant difference between the two populations? What conclusion can you draw from this information? (5 points, 2 for answer, and 3 for showing work)
Answer:
Yes.
Explanation:
Yes, there is a statistically significant difference between the two populations of green sea turtle because the turtle lay eggs on the beaches of the ocean so human presence at the beach damaged eggs and lead to the decrease in population of green sea turtle while on the other hand, there is high population of green sea turtle due to no human presence or activities in the remote Island.

Specifically how did Mary Mallon spread typhoid bacteria (Salmonella typhi) to the families she cooked for, as cooking food kills bacteria
Answer: Mary Mallon was able to spread the typhoid bacteria to the families she cooked for even as cooking kills bacteria because she was a healthy carrier of salmonella typhi who prepared certain foods for these families, that doesn't require cooking, without vigorously scrubbing her hands.
Explanation:
The genus salmonella consists of a group of bacilli which can affect man leading to the following conditions:
--> Enteric Fever
--> Gastroenteritis
--> Septicaemia and
--> Carrier state or condition.
Salmonella typi causes the enteric fever called TYPHOID FEVER. A healthy individual can be infected with the bacteria through injection of faecal contaminated food ( faeco- oral route). On reaching the gut,the organism attach themselves to the intestinal villi penetrating the lamina propria and submucosa. Their major factor of virulence is the inability to be killed after being phagocytosed by polymorphs and macrophages. They enter the blood stream through the thoracic duct causing transient bacteriaemia. During this period, the bacilli are then seeded into the liver, kidney and gall bladder where further multiplication occurs. The massive discharge of these bacilli from gall bladder leads to onset of the clinical disease.
These bacilli tends to persist in the kidney and gall bladder( as it's a good culture media for the organism). These are seen in individuals who become carriers following inapparent infection and they are called HEALTHY CARRIERS. They shed the bacilli intermittently from their faeces and urine
Mary Mallon, an Irish cook, was a healthy carrier of salmonella typhi who constantly shed the bacteria in her faeces and urine. Although the bacilli is destroyed when subjected to high temperature ( when cooking), the families she cooked for still came down with the illness. This was so because, since the bacteria can be transmitted through faeco- oral route, she wasn't educated enough to vigorously scrub her hands before handling foods that doesn't require cooking,for example vegetable salads.
