Explanation:
Answer: Messages to and from the brain travel along the nerves, which are strings of long, thin cells called neurons (see Figure 6.2). Chemical- electrical signals travel down the neurons much as flame travels along a firecracker fuse. ... Dendrites receive impulses, or messages, from other neurons and send them to the cell body.

LAKE WATER is NOT an example of a climate proxy.
A climate proxy refers to any preserved physical feature of the past, which can be used to study climatic conditions over a determined period of time.These features (climate proxies) help to reconstruct past meteorological conditions and thus understand how Earth has been affected by climatic factors during different periods of time.Some organisms that can be used as climate proxies include diatoms (algae), forams, and corals.In conclusion, LAKE WATER is NOT an example of a climate proxy.

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.

Why is breaking and rearranging bonds in the process of photosynthesis and cellular respiration important? WILL GIVE BRAINLIEST
Answer:
Breaking and rearranging bonds in the process of photosynthesis and cellular respiration is important because energy is released when bonds are broken in both processes. This energy is used to fuel cellular activities. Bonds are rearranged in the process of photosynthesis to make molecules of glucose; this glucose is used to fuel the process of cellular respiration, in which bonds are rearranged to form molecules of water and carbon dioxide.
In photosynthesis and cellular respiration breaking and rearranging, bonds release energy.
How is the energy released in respiration?ATP, NADH, and FADH are used to store the energy that is produced when carbon bonds are broken and rearranged in living things. Every time you exhale, carbon dioxide is expelled because cells cannot utilize it.
The extremely valuable ATP molecules are readily available to fuel cellular activity. Sugars are broken down by animal and plant cells to produce useful energy.
By severing chemical bonds and building new ones while rearranging atoms, these and other chemical processes transform materials into other compounds.
Therefore bonds release energy so breaking and rearranging bonds in the process of photosynthesis.

Answer:
Pheomelanin
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.
Thus, option "B" is correct, Dark-skinned individuals produce more melanin than those with pale skin.

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%.

Compare Suspect 1 (S1) and Suspect 2 (S2) to the DNA evidence sample (E). Based upon the DNA fingerprints, which suspect was likely at the crime scene and why
Hello. Your question is incomplete and more information would be needed so that it could be answered accurately. However, I will try to help you in the best possible way.
As we know, fingerprints are formed by a unique pattern of lines that are not repeated between individuals. Thus, in order to discover who is a criminal, through the analysis of fingerprints, it is important to identify the pattern of lines left at the scene of the crime and analyze it with the pattern of lines in the suspect's fingerprint.
