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

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 .

The following genotype/phenotype relationship applies to these two genes: R- P- animals have a 'walnut' comb; R- pp animals have a 'rose' comb; rr P- animals have a 'pea' comb; rr pp animals have a 'single' comb. What will the comb phenotypes of the progeny be for a cross of rr PP X rr Pp animals
Answer:
100% of the progeny will have a pea comb, rrP-

How does movement of the legs affect the gills of crabs?
Answer:
The beating or fanning movements of three pairs of maxilliped flagella in crabs and crayfish modify exhalent gill currents while drawing water over chemoreceptors on the head. They play an integral part both in signalling by distributing urine odours, and in active chemosensation.

Explanation:
At carrying capacity, the number of organisms being born equals the number of organisms
competing
dying
surviving
immigrating
Answer:
dying
Explanation:
carrying capacity is where there is only a certain amount animals can enter so the animals being born is the same as the animals dying bc they have no resources

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.
