egarding food safety, a. explain whether there is a greater risk for e. coli o157:h7 infection when consuming a hamburger compared to consuming a steak. b. also, discuss whether or not food poisoning can still occur after consuming a reheated pot of soup known to be contaminated with staphylococcus aureus.

Answers

Answer 1

A. E.coli O157:H7 is a pathogenic strain of E.coli causing diarrhea in humans. It produces the shiga toxin which is responsible for the illness. E.coli O157:H7 infects the intestinal epithelial cells.

Ground meat is used to prepare hamburgers. Most food gets contaminated with E.coli when the amount of handling increased. In case of ground meet, the beef has to be pulverized in order to make the hamburger patty. As this process involves many stages, there is more risk of contamination in hamburger patty. A steak on the other hand is only cut out meat,. So there are chances of contamination only on surface. The inner surfaces are relatively free of contamination. If the steak is cooked medium rare, most of the bacteria will be killed. As there are lesser chances of contamination in inside of the steak, the steak will have less chances of contamination. Pathogenic strain of E .coli is killed at temperature above 70 degree centigrade. It is possible that if the hamburger patty is cooked medium rare, the inside of the patty may not reach that temperature and kill pathogenic E.coli. Hamburger and steak should not be consumed rare. However, if cooked medium rare, steaks are safer than hamburgers to consume.

B. S. aureus is  known to cause infections in humans. When the food is cooked, S. aureus should be killed. However, it can get decontaminated when handled later on, after cooling. This allows the growth of S. aureus. When food is reheated, the reheating will kill the S. aureus. But S. aureus is known to produce heat stable enterotoxins. These enterotoxins will survive the reheating and can cause staphylococcal food poisoning. These enterotoxins include SEA-SEE, SIG-SIK, which are mainly responsible for the food poisoning. Very low amounts of these toxins are sufficient to cause food poisoning in humans. Hence, staphylococcal food poisoning can still occur even when the S. aureus is destroyed after reheating.  

What is enterotoxin?

A material that is bad for your digestive system is called an enterotoxin. It is created by certain microorganisms. If you consume contaminated food or water, the enterotoxin will enter your stomach and intestines. Symptoms like cramps, nauseousness, vomiting, or diarrhoea are brought on by this.

What does "moving slow" mean to a geologist?
Why do you think it is difficult to tell that the plate beneath you is moving right now?

Answers

"Moving slow" to a geologist refers to the rate at which tectonic plates are shifting.

What does "moving slow" mean to a geologist?This movement is measured in centimeters per year, which is considered a slow rate compared to other geological processes.It is difficult to tell that the plate beneath you is moving right now because the movement is occurring very slowly and is not perceptible to the human eye. Additionally, the movement is hidden underground and can only be measured using sensitive instruments.The phrase “moving slow” is used to describe tectonic plate movement. Tectonic plates are large sections of the Earth’s crust, and they move in relation to each other at speeds of a few centimetres to a few metres per year. This movement is what is responsible for the formation of mountains, earthquakes, and volcanoes. It is difficult to tell that the plate beneath us is moving right now because the speed of plate movement is so slow. Though it could be measured using instruments, most of us don't have access to them. Even if we did, it would take a long time to measure a significant shift in the tectonic plates. Furthermore, the ground beneath our feet is not a homogeneous surface. It is composed of many different materials, with different densities and strengths. This means that the plates will not move uniformly, complicating the process of measuring movement.

Answers

B) chemical bond energy of ATP released when the bond breaks

is a source of the activation energy needed to reach the transition state intermediate.

The energy needed to start a chemical reaction and get to the transition state, where the reactants have enough energy to break through the activation energy barrier, is known as activation energy. Using an energy carrier molecule like ATP is one approach to supply this energy. The energy that can be used to produce the activation energy for the chemical reaction is released when a phosphate bond in ATP is broken. The molecules collide with enough force to achieve the transition state and start the chemical reaction once this energy is transformed into kinetic energy.

Answers

Channel is known as facilitated diffusion. Aquaporins are proteins that act as channels in the cell membrane to allow water to pass through.

What is facilitated diffusion?
Facilitated diffusion
is a type of passive transport process where molecules or ions are transported across a plasma membrane with the help of carrier proteins. It is a vital part of the cell's membrane transport system and can move solutes in and out of the cell. Unlike simple diffusion, facilitated diffusion does not require any energy expenditure. This type of transport is especially important for molecules that cannot pass through the membrane on their own, such as glucose. The carrier proteins bind to the molecules on one side of the membrane, then undergo a conformational change that allows them to move across the membrane, and finally release the molecules on the other side. This process is constantly occurring in cells and helps maintain cellular homeostasis.

the domain of life that is characterized by having histone proteins, and membrane bound nucleus and organelles [x]

Answers

The domain of life characterized by having histone proteins, and membrane bound nucleus and organelles is Eukarya.

How does the presence of histone proteins, a membrane-bound nucleus and organelles contribute to the organization and function of eukaryotic cells?

The presence of histone proteins, a membrane-bound nucleus, and organelles contribute to the organization and function of eukaryotic cells in several ways:

Histone proteins act as a "scaffold" to package and organize the DNA within the nucleus, making it more compact and allowing for efficient storage and expression of genetic information.

The membrane-bound nucleus serves as a barrier to separate the genetic material from the rest of the cell, protecting it and controlling the flow of molecules in and out of the nucleus. This allows for the regulation of gene expression and cell function.

Membrane-bound organelles such as mitochondria and chloroplasts perform specific functions within the cell. Mitochondria generate energy for the cell and chloroplasts perform photosynthesis in plants. This compartmentalization allows for efficient organization and performance of cellular functions.

Together, these structures allow for the efficient organization, regulation, and performance of cellular functions, contributing to the overall functioning and survival of eukaryotic cells.
