A food handler who fails to report illness to the person in charge could cause a physical contamination?
Answer:
True
Explanation:
Physical contamination are foreign objects such as hair, fingernails, broken glasses , jewelries etc that are mixed with food. Although, it is important for a food handler who realizes that he is sick such as having fever, jaundice,wound while working to report such to his supervisor or manager,who will then take necessary action and to avoid risk of contamination; yet not the only cause of physical food contamination.
Physical contamination does not necessarily have to occur until the food handler is sick. It could be as a result of carelessness or not paying attention enough by the food handler . Physical contamination might not at all times cause injury or illness to the customer, yet such could bring discomfort to a customer who notices foreign objects in his food while eating. To avoid risk of physical food contamination, it is important for food handlers to keep jewelries to a minimum, wash fruits and vegetables thoroughly, wear hear neatly tied back, throw out and replace cracked, chipped, or broken dishware, glassware and equipment amongst others.

Partical A has very little mass in comparison to partical B. Both Particals are in the same atom. which is the best conclusion about Particals A and B?
A. They have opposite charges
B. They are located in the nucleus together.
C. Partical A has a negative charge, and Partical B is neutral.
D. Partical A orbits the nucleus, and Partical B is located in the nucleus
Answer:
D. Particle A orbits the nucleus, and Particle B is located in the nucleus
Explanation:
Here since both particles are of the same atom and particle A is much lighter we can infer that Particle A is electron because electrons are much lighter than protons which are Particle B in this case. Thus, particle A orbits nucleus as an electron does and particle B is in nucleus where protons are.

What is the basic purpose of cellular respiration? What are the reactants and products of cellular respiration overall? Also, give a basic description of the three main stages of cellular respiration (glycolysis, Kreb cycle, and the electron transport chain)
Answer:
The Main basic purpose is to be able to breath and live. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.The three main stages of cellular respiration (aerobic) would include Glycolysis, the Krebs Cycle and the Electron Transport Chain. The Krebs Cycle takes Citric Acid which is a derivative of Pyruvic Acid and converts this through 4 cycles into Hydrogen, carbon dioxide and water in the Mitochondrial Matrix.

A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound B. If a chemist uses 255 milliliters of compound A, how many milliliters of the drug will be made?
----------------------------------
4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.
---
Solve for "x":
If amount of compound A is 4x = 255
x = 255/4
------------------------------
Then amount of compound B is 5x = 5(255/4) = 318.75 ml

After getting the slide and microscope ready, Stella is eager to see the microscopic pond water specimen! She crouches around her microscope and aligns her eye with the microscope’s eyepiece. But she's only able to see a bright white light. At this point, no specimens or cells are visible on Stella's pond water slide. After taking a moment to collect her thoughts, Stella realizes she can't see any lifeforms because a.the microscope is not yet in focus b.the microscope is not plugged in c.there are no specimens on the slide d.she hasn't fastened the slide to the stage
Answer:
she hasn't fastened the slide to the stage
Explanation:
In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.
If the microscope is not plugged it light can not come up.
If there are no specimen on the slide,the slide will still as transparent image at the focus.
No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.
Students make these mistakes in microscopy,they sometimes place the slide on the stage,but forget to fasten the stage clip,thus the slide is not in focus of the incident light,which gives no reflection to the viewer's eyes.
Which of the following statements associated with cellulose is false? A) It's a linear polymer of glucose. B) The glycosidic linkage is β(1 → 4). C) Hydrolysis is accomplished enzymatically by cellulase. D) Most animals can easily digest this compound.
Answer:
Most animals can easily digest this compound
Explanation:
Cellulose is a linear polymer of glucose comprising of beta 1,4-glycosidic linkage of glucose molecules; this is where it differs from starch. Cellulose is a polysaccharide made of glucose monomers just like starch. The enzymatic hydrolysis of cellulose is achieved by the enzyme cellulase.
Not all animals can digest cellulose. As a mater of fact, no vertebrate can digest cellulose directly. Many herbivorous animals possess symbiotic bacteria in their gastrointestinal tract which enables the digestion of cellulose. These bacteria possess the requisite enzymes for the digestion of cellulose.
Q. Habitat loss occurs due to agriculture, forestry, and other human activities. Describe the effect of these activities on species diversity in the ecosystems in which they occur, and how this would affect the stability of these ecosystems over time.
Answer:
Explanation:
Human activities had led to diversity of species in ecosystem. Some of the species of animal have been lost and displace due to human activity such as deforestation, construction, company establishment.
Clearing of land for agriculture use has also contributed to diversity that occur in the habitat of an animal.
Diversity of an habitat leads to an unstable ecosystem, as animals can no longer thrive and live in their environment, some species of animals are lost including important species in the environment in the process and others struggles to survive.
Reduction of human activities in animals natural habitat can help restore diversity.
: Which of the following is not a sign of sepsis? Which of the following is not a sign of sepsis? increased white blood cell count body temperature above 101°F (38.3°C) or below 96.8°F (36°C) increased respiratory rate (more than 20 breaths per minute) dilated pupils rapid heart rate (more than 90 beats per minute)
Answer: The correct answer to the question is DILATED PUPILS.
DILATED PUPILS is not a sign of sepsis.
Explanation: Sepsis can be defined as the way our body system respond to infection or invasion of a foreign body into the body system.(usually bacterial infection)
When Sepsis becomes severe,it is injurious to organs of the body(affects their function in a negative way).
Sepsis occurs when the body's immune system tends to fight infection in the body by the release of certain chemicals(cytokines and prostaglandins),the body instead of reacting in a coordinated manner to these chemicals rather reacts out of proportion to these chemicals released to fight infection and this will lead damage to organs of the body system.
Sepsis is characterised by Fever(above 101°F (38.3°C) or below 96.8°F (36°C), increased in respiratory rate (more than 20 breaths per minute), Increased heart rate (more than 90 beats per minute),increased white blood cell count,low blood pressure and mental confusion.
Treatment of Sepsis includes the administration of antibiotics and intravenous fluid, administration of drugs to support blood pressure and administration of steroids.
Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. Based on the pedigree that is shown, which describes John? A)carrier for hemophilia B)expresses hemophilia C)does not have hemophilia D)expresses hemophilia and died of complications
Answer:
C) Does not have hemophilia
Explanation:
When a pedigree is half shaded, the person is a carrier.
When a pedigree is not shaded, the person doesn't express the gene.
When a pedigree is completely shaded, the person is affected.
Square usually is male and circles are usually female.
Since John is the non-shaded square and parent of 4 offspring, he does not have hemophilia. However, his wife is a carrier, and that's how their offspring have hemophilia.

an Association between the root noodles of leguminous plant and rhizobium SP is known as what
Answer:
The question lacks options, the options are:
A. commensalism
B. mycorrhiza
C. parasitism
D. symbiosis
The answer is D, symbiosis (mutualism)
Explanation:
Organisms of same or different species interact with one another in their natural environment. The relationship between two organisms interacting with one another is called SYMBIOSIS. Symbiosis can be of different types depending on the effect of the relationship on the involved organisms. Symbiosis can be mutualistic, commensalistic or parasitic.
Mutualism is a kind of symbiosis in which the involved organisms benefit from the actions of one another. This is a case of the association between the root nodules of leguminous plant and rhizobium species.
Rhizobium is a bacteria genus found in the soil. They form nodules by attaching to the root of leguminous plants, which helps the plants to fix atmospheric nitrogen i.e converting gaseous nitrogen to a usable form (ammonia). In return, the plants provide organic acids for the Rhizobia bacteria, which they use as carbon and energy source. Hence, the association is a symbiotic relationship and specifically a mutualistic one.
The answer is no mycorrhiza because it is an association between a FUNGUS and a plant.
