What type of microbe is used in a vaccine .
Answers
Answer:
answer is below
Explanation:
Several of these structures have been used to generate bacterial vaccines. Toxoids are chemically inactivated toxins from bacteria like Clostridium tetani or Corynebacterium diphtheria. The infection with these bacteria itself does not cause the illness, but rather the exotoxins released from the bacteria.
Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine.

Invert syrup is a widely used sweetener, especially in candies and highly processed foods. Invert syrup can be made by treating sucrose with either an enzyme called sucrase or by heating sucrose with an acid. The end result is the same: each molecule of sucrose is hydrolyzed, resulting in _
Answers
Answer:
one glucose and one fructose molecule
Explanation:
Generally, inverted sugar is a mixture of two monosaccharides or simple/reducing sugars. More specifically, inverted sugar is a mixture of glucose and fructose.
Sucrose is a disaccharide containing one molecule of glucose and one molecule of fructose. Hence, when hydrolyzed, the glycosidic bond linking the glucose molecule with the fructose molecules becomes broken and the resulting product is a mixture of glucose and fructose molecules in equal proportions.
Give ttwo pieces of information that scientists use to prepare evolutionary trees for living and extinct organisms
Answers
Two pieces of information that scientists use to prepare evolutionary trees for living and extinct organisms are the fossil evidence that is found on the earth and the DNA samples, as these two are helpful in the evolutionary tree representation.
What is the significance of the evolutionary tree?An evolutionary tree, or phylogenetic tree, is a diagrammatic representation that shows the relationships between different species or groups and is used to represent the evolutionary history and how organisms are related to one another through common ancestry. The evolutionary tree is important as it helps scientists understand the relationships between different species and how they have evolved over time to form new species.
Hence, two pieces of information that scientists use to prepare evolutionary trees for living and extinct organisms are the fossil evidence that is found on the earth and the DNA samples, as these two are helpful in the evolutionary tree representation.

Health researchers measure how often people exercise and how often the same people come down with the flu. The researchers find a negative correlation between the amount of weekly exercise and the number of flu symptoms in an individual. Based on this information, which of the following can we assume are TRUE?
a. People who exercise more tend to have the flu less often.
b. People who have the flu more often tend to exercise less.
c. Exercising causes people to be more healthy and less susceptible to the flu.
d. People who get sick do not have time to exercise.
e. Since exercise reduces the flu, this is really positive correlation because the result is good.
f. Since the flu is a bad thing, this makes it a negative correlation.
Answers
Answer:
a, b, and c
Explanation:
Generally, correlation measures the strength of the relationship that exists between two variables. A positive correlation means that the two variables have the tendency to either increase or decrease together while a negative correlation means that the two variables tend to move in opposing directions, that is, as one is increasing, the other is decreasing and vice versa.
Now, the researchers find a negative correlation between the amount of weekly exercise and the number of flu symptoms in the subjects. This means that the more the exercise, the lesser the number of flu symptoms and the lesser the exercise per week, the more the flu symptoms. Hence, the assumptions that can be made directly or indirectly from the findings include
People who exercise more, get sick or have flu less often.People who have the flu more are most likely exercising very little or not at all.Exercising causes people to be more healthy and less susceptible to the flu.The correct options are a, b, and c.

discuss the contributions of pasteur, and koch to 'germ theory of disease' and to the prevention of diseases
Answers
Answer:
Pasteur showed that putrefaction is a process associated with organisms present in the air, while Koch identified the germs that cause different diseases
Explanation:
The germ theory states that pathogenic microorganisms called germs cause the disease state observed in a particular (infected) organism. The term 'germ' includes pathogenic bacteria, protists, fungi, and even non-living pathogens (e.g., viruses). This theory was developed and accepted due to the work of Louis Pasteur and Robert Koch. In the 1860s, Pasteur showed that germs were omnipresent in a flask open to the air, showing that putrefaction and fermentation are caused by these microorganisms. Moreover, in the 1880s, Koch identified the germs that cause different diseases, including tuberculosis (Mycobacterium tuberculosis) and cholera (Vibrio cholerae).

If you cross a white-eyed female (ww) to a red-eyed male (WY) Drosophila fly, you will see red-eyed females and white-eyed males in the F1 generation. If you cross an F1 red-eyed female to an F1 white-eyed male, what is the approximate percentage of total progeny in the F2 generation that are white-eyed males
Answers
Answer:
25%
Explanation:
ww gives white-eye female
WY gives red-eye male
ww x WY
F1: Ww wY Ww wY
Ww - red-eye female
wY - white-eye male
Crossing the two F1
Ww x wY
F2: Ww WY ww wY
Remember that white-eye male = wY
Percentage of wY = 1/4 or 25%
Hence, the percentage of progeny in the F2 generation that would be white-eye males = 1/4 or 25%

What general types of tissue have been afflicted?What type of burn has Matt received? Explain.List ALL layers of the skin that have been damaged.What tissue repair process causes the blistering?List all of the body functions that may be disrupted by such a burn.After a few days his skin peels and the burned areas begin to heal. Matt notices that the healing areas are more susceptible to injuries due to chafing or trauma. During the next week after Matt returns to Tampa, Maria tells him that a sunburn prepares his skin for a deep tan. Maria encourages him to quickly begin tanning sessions at a local tanning salon before the effects of the burn wear off.What has happened to the skin that would cause this increased susceptibility?What would you advise him to do?

The question the scenario shows suggests, the integumentary system of Matt is affected, this system is part of the skin.
What is sunburn?A person having lesser melanin content in their skin has the risk of developing redness, swelling, and pain in the skin indicative of cellular damage caused by excessive sun UV radiation, this is known as sunburn.
Matt received a second-degree sunburn, which affects the dermal and epidermal layers of the skin. The inflammatory stage, proliferation stage, and matrix remodeling are the tissue repair process.
The skin is the first line of defence and acts as a barrier, after this injury affect this line of defence is affected causing entry of pathogens inside the body.
In absence of the epidermis, when the dermis is exposed, easily bruises and injury occur since blood vessels are exposed to the skin's surface.
Therefore, excessive exposure to the UV light creates deep tan signs.
