Answer:
Biotechnology is the use of biological techniques and engineered organisms to make products or plants and animals that have desired traits.
Explanation:
People have used biotechnology processes, such as selectively breeding animals and fermentation, for thousands of years. Late 19th and early 20th century discoveries of how microorganisms carry out commercially useful processes and how they cause disease led to the commercial production of vaccines and antibiotics. Improved methods for animal breeding have also resulted from these efforts. Scientists in the San Francisco Bay Area took a giant step forward with the discovery and development of recombinant DNA techniques in the 1970s. The field of biotechnology continues to accelerate with new discoveries and new applications expected to benefit the economy throughout the 21st century.
In its broadest definition, biotechnology is the application of biological techniques and engineered organisms to make products or modify plants and animals to carry desired traits. This definition also extends to the use of various human cells and other body parts to produce desirable products. Bioindustry refers to the cluster of companies that produce engineered biological products and their supporting businesses. Biotechnology refers to the use of the biological sciences (such as gene manipulation), often in combination with other sciences (such as materials sciences, nanotechnology, and computer software), to discover, evaluate and develop products for bioindustry. Biotechnology products have made it easier to detect and diagnose illnesses. Many of these new techniques are easier to use and some, such as pregnancy testing, can even be used at home. More than 400 clinical diagnostic devices using biotechnology products are in use today. The most important are screening techniques to protect the blood supply against contamination by AIDS and the hepatitis B and C viruses.

what is the female reproductive system cell
Answer:
Egg
Explanation:
Reproductive system is the system of an organism encompassed with the function of giving rise to new offsprings. In sexual reproduction, which involves two organisms, one of the organisms is usually a MALE while the other is a FEMALE.
In most sexually reproducing organisms, the female reproductive system undergoes a division called MEIOSIS to produce a sex cell or gamete called EGG CELL. This egg cell gets fertilized by the sperm cell produced by the male to form a zygote. Hence, EGG CELL is the female reproductive system cell.
Answer:
the egg

Why is price discrimination not positive under perfect market conditions
Answer:
[u9gbvolgj;t9ug7yh
Explanation:
ft7odt8ugde86rfgef
Price discrimination is impossible in a market with perfect competition, and the average total cost (ATC) curve is identical to the marginal cost curve (MC).
What is price discrimination?Price discrimination is a sales strategy in which the seller charges different prices for the same item or service oriented on what the seller believes the customer will agree to.
In sheer price discrimination, the seller charges each customer the highest possible price.
Price discrimination occurs when various prices are charged to different customers.
This is not feasible in a perfectly competitive market because there are numerous firms competing for the price; however, it is possible in a monopoly because people have no other place to buy.
In a monopoly, price discrimination is the practice of charging different prices for a product.
Monopolies typically have greater control over providers than regular sellers, allowing them to significantly influence the selling prices of the suppliers.
Thus, due to this, price discrimination is not positive even under perfect market conditions .

A bacterial isolate is subcultured to two blood agar plates, one of which is incubated in an anaerobic jar, and the other is incubated on a shelf in the incubator. After incubation, growth is observed on the plate from the anaerobic jar, but there is no growth on the plate incubated on the incubator shelf. Based on these results, how would this organism be categorized
Answer: obligate anaerobe
Explanation: This experiment established that a bacterial isolate is subcultured into same medium in two different plates, but one is placed in an aerobic condition (i.e., presence of oxygen) while the other in an anaerobic condition (i.e., absence of oxygen), and the result shows that there was no growth on the plate incubated on the incubator shelf, whereas there was growth on the plate conditioned anaerobically.
This simply translates that the bacterium does not need oxygen to grow i.e., It’s an anaerobe. Moreso, assuming it grows on the two plates we would say it's a facultative anaerobe.
Thus, since it growth was only established on the plate with anaerobic condition, it's an obligate anaerobic bacterium.
Which of the following describes research that would be considered basic science? A. A professor at a university is observing the mating behavior of freshwater fish, B. A dairy farmer is designing a new machine for milking cows. c. Park rangers are trying to find out why a group of elm trees died. D. Doctors in a hospital are developing a new surgical technique.
Answer:
C. But be careful. This question is poorly conceived. Anything could be the answer.
Explanation:
A B and D are all specific to the disciple they are involved in.
That only lets you choose C. You could argue that a physicist or an electrical engineer would not be particularly interested in the death of some elm trees, and I think I would agree with you.
But what other choice to you have?
While the professor is tracking the fresh water fish, how is that benefiting mankind? What is he learning that is universally applicable. I wouldn't choose A.
B is an advance in technology. It might make the dairy farmer's life a whole lot easier, but I don't think it would have very effect on anyone else. Not B.
D: Again this benefits surgeons but again it is technology. I don't think it universally benefits all of humanity except those who are going to be operated on.
So I'll stick with C. People die. So do trees and all vegetation. I'd pick C, but I don't think there is a clear cut answer. Sometimes you get questions that you think the answer resides only in the head of the person writing the question. This is one of them.

1) What is the control group? 2) What is the experimental group? 3) What is the independent (manipulated) variable? 4) What is the dependent (responding) variable? 5) What should Tina's conclusion be?
Complete question:
Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscopes, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.
1) What is the control group?
2) What is the experimental group?
3) What is the independent (manipulated) variable?
4) What is the dependent (responding) variable?
5) What should Tina's conclusion be?
Answer:
Individuals from test 1Individuals from test 2CaffeineHeart rateTina´s hypothesis is correct. Caffeine increases the heart rate of an earthworm.Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one affected by the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually represented using the letter Y. Controlled variable: Refers to the variables that have no influence on the results. These variables do not affect the change in the dependent variable values.1) What is the control group?
Individuals from test 1 compose the control group. They are not affected by the treatment. Tina just uses them to measure the normal heart rate and to compare them with individuals from test 2.
2) What is the experimental group?
Individuals from Test 2 compose the experimental group. They are affected by the treatment. Tina drops caffeine on their skin to see how it affects the worms.
3) What is the independent (manipulated) variable?
Caffeine is the independent variable. Tina manipulates the number of drops she places on the worm´s skins.
4) What is the dependent (responding) variable?
Heart rate is the dependent variable. Tina evaluates how the heart rate changes in individuals with or without caffeine.
5) What should Tina's conclusion be?
Caffeine increases the heart rate of an earthworm. It changes from 50 to 68 bpm. Tina´s hypothesis is correct.

The most muscular pump in the heart is the: *
septum
left atrium
left ventricle
right atrium
right ventricle
Answer:
The heart has four chambers and four main blood vessels that either bring blood to the heart, or carry blood away.
The four chambers are the right atrium and right ventricle and the left atrium and left ventricle. The blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium. Next is the pulmonary artery that carries blood from the right ventricle to the lungs. The aorta is the body's largest artery. It carries oxygen-rich blood from the left ventricle to the rest of the body.
Beneath the tough fibrous coating of the heart, you can see it beating.
Inside the chambers are a series of one-way valves. These keep the blood flowing in one direction.
Dye injected into the superior vena cava, will pass through all the heart's chambers during one cardiac cycle.
Blood first enters the heart's right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle.
When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs.
In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.
From there, blood is forced through the mitral valve into the left ventricle. This is the muscular pump that sends blood out to the rest of the body.
When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta.
The aorta and its branches carries the blood to all the body's tissues.
