The level of glucose in the bloodstream drops. The person requires glucose in cells to meet the demand for ATP (glucose is broken down to create ATP). The body detects glucose levels with a particular receptor designed for this function. These receptors release hormones, chemical messages that initiate the start of the feedback mechanism. The hormones travel to their target tissue and initiate a corrective response. In this case, the corrective response is the secretion of more glucose into the bloodstream. Does this demonstrate POSITIVE or NEGATIVE FEEDBACK?
Answer:
Negative feedback.
Explanation:
It is negative feedback because the reactions triggered by low glucose levels are trying to rebalance the glucose concentrations in our body to make it work properly.
In positive feedback, a product will only stimulate more the components that lead to that product to produce more of it, increasing the product's effect and an imbalance.

Answer:
The solar eclipse
Explanation:
When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. ... But lunar eclipses do not occur every month because the Moon's orbit is tilted five degrees from Earth's orbit around the Sun.

Air moves in a direction that creates land breezes.
Air above land warms faster than air above water.
Air blows over long distances in a continual straight path.
Air pressure remains the same while cycling over land and water.
Answer: Air moves in a direction that creates land breezes.
Explanation:
The arrows indicate is air moves in a direction that creates land breezes. So, the correct option is A.
What are Land breezes?Due to the difference in temperature of land and sea, land breezes are those winds which blow from land to sea at night.
The Sun heats both land and sea during the day, but land heats up more quickly than water. As a result, an area of low pressure is generated as the air above the ground is heated and rises. As a result, cold sea air fills the space and creates a sea breeze that blows from sea to land.
The opposite happens at night. The air over the land becomes cooler and denser because the land cools faster than the sea. As a result, high pressure develops over the land. Then a land breeze is generated, which flows from land to sea by cold and dense air moving from land to sea.
So, the correct option is A.

Emily has a maternal grandfather who is colorblind, which is an X-linked
recessive trait. Everyone else in her family sees normally. Emily's mom is
expecting a new baby girl. What is the chance that the new baby will also
be colorblind?
A. There is no chance that the new baby girl could be color blind.
B. There is no way to determine this from the information provided.
C. There is a 25% chance that the new baby girl will be colorblind.
D. There is a 50% chance that the new baby girl will be colorblind.
Answer:
A
Explanation:
the father doesn't have the trait and since it's recessive, there's no way the baby could have it even if the mother carries it from the grandfather.
There is a 25% chance that the new baby girl will be colorblind. Therefore, the correct option is C.
What is colorblindness?Color blindness is an X-linked recessive trait. This means that the gene responsible for color blindness is located on the X chromosome, and the trait is expressed only when there are two copies of the gene, one on each X chromosome, in females. Males have only one X chromosome, so they will express the trait if they inherit the colorblind gene.
In Emily's family, her maternal grandfather is colorblind. This means that Emily's mother is a carrier of the colorblind gene, since she does not have the trait herself. Emily's father must have two normal copies of the gene, since he does not have color blindness.
When Emily's mother and father have a child, there are four possible combinations of their genes that the child could inherit:
Normal X from mother, Normal X from father (25% chance)
Normal X from mother, Colorblind X from father (25% chance)
Colorblind X from mother, Normal X from father (25% chance)
Colorblind X from mother, Colorblind X from father (25% chance)
Only the last combination would result in a colorblind female, since she would have two copies of the colorblind gene. Therefore, the chance that the new baby girl will be colorblind is 25%.

define atomic number and mass number – describe how they differ
Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.

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.

Explanation:
Dark-skinned individuals produce more melanin than those with pale skin.
Light-skinned people typically have a greater proportion of pigment in their skin Pheomelanin, Dark-skinned persons produce more melanin than those with pale skin.Thus, option "B" is correct
What is the difference between pheomelanin and eumelanin?
Eumelanin is black or brown tint and pheomelanin is red or yellow pigment.
Individual who create lots of pheomelanin tend to have lighter skin, often because of freckling.
Freckles occur when melanocytes clump together. Melanocytes are generally scattered rather evenly in the skin.
