Is a plant that has the natural ability to protect itself against predation a genetically engineered organism
Answer:
No, genetically engineered organisms are engineered by humans. The plant evolved to be this way.
Explanation:
Answer:
If it's a natural ability for the plant, it's probably not genetically engineered. It depends on the plant species/fruit.
Explanation:
Predation: A biological interaction where one organism, the predator, kills and eats another organism, its prey.
Genetically Engineered Organism: An animal, plant, or microbe whose DNA has been altered using genetic engineering techniques.
In most cases with let's say a pepper plant, the plant will produce a chemical compound called capsaicin. This is what makes the peppers spicy. It really just depends on the plant we're talking about.
¿Qué sucede con un pasajero que está de pie en un autobús cuando este inicia el
movimiento?
¿Por qué sucede eso?
Answer:
El pasajero se mueve hacia atrás.
Explicación:
Cuando el autobús comienza a moverse hacia adelante, el pasajero que está parado en un autobús se mueve hacia atrás debido a la inercia. La inercia es una propiedad en la que un cuerpo resiste cualquier cambio en su estado de reposo o movimiento. Al principio, el pasajero está en reposo, por lo que cuando el autobús comienza a moverse en la dirección de avance, el pasajero se mueve en la dirección de retroceso para permanecer en reposo debido a la propiedad de la inercia. Por eso el pasajero se mueve hacia atrás.

According to the Punnett Square shown above
A.
there is a 50% probability that an offspring will have brown eyes and a 50% probability that an offspring will have blue eyes.
B.
there is a 75% probability that an offspring will have blue eyes and a 25% probability that an offspring will have brown eyes.
C.
there is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.
D.
there is a 100% probability that an offspring will have one brown eye and one blue eye.
Answer:
C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.
Explanation:
Note that the brown eyes is the dominant trait, denoted by B, while blue eyes is the recessive trait, denoted by b. In all cases of the Punnett square, if there is a dominant and recessive trait, the dominant trait will always come out on top.
The given Punnett square:
[tex]\left[\begin{array}{ccc}&B&b\\B&BB&Bb\\b&Bb&bb\end{array}\right][/tex]
Note that there are 3 options (BB, Bb, Bb) respectively, in which there is the dominant trait B (brown eyes). Only in one case is there only the recessive trait b (blue eyes), or a 1/4 chance of obtaining blue eyes. Therefore, there is a 3/4 chance of obtaining a brown eye:
C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.

Scientists once thought that life spontaneously arose from nonliving things. It took extensive experimentation and the invention of new technology to confirm the tenets that now make up the cell theory. Now, we don't even question that cells are the basic units of life and only come from preexisting cells. What technology had the biggest impact on the development of the cell theory?
A) centrifuge
B) electrophoresis
C) microscope
D) telescope
Answer:
Microscope.
Explanation:
Microscopes were extremely influential in the development of cell theory, as they allow us to see down to the level of cells and observe them. Through process of elimination, we know it cannot be a telescope (used for observing large, far away objects) or a centrifuge (separates substances based on density). Electrophoresis is moreso used for DNA, and not for the entire cells.
You are studying a disorder that is based on the genetic composition at three loci. Assume that a dominant allele at any locus adds 5 units of risk for the disorder and that a recessive allele at any locus adds 3 units of risk for the disorder. Individuals with 26 or more units of risk develop the disorder. The environment does not affect the presence or absence of this disorder. How many risk units will be present in an individual of genotype AABbcc
Answer:
24
Explanation:
Given that:
At either locus, the expression of the dominant allele increases the risk by 5 units.
The assigned genetic sequence "AABbcc" has three dominant alleles, implying that it increases risk by 15 units.
At any locus, the expression of the recessive allele increases the risk by three units. The assigned genetic sequence "AABbcc" has three recessive alleles, which means it increases the chance by 9 units.
In an individual with the genotype AABbcc, the total number of risk units is = 15+9 = 24. This implies that the person does not develop the disease).

Return to the MyPlate food plan calculator, and make an eating plan for someone whose weight and age are different from yours. You can change the person’s age, gender, and activity level. How does this checklist differ from yours? Why do you think the person’s energy needs are different?
Answer:
Increase consumption of food to increase weight.
Explanation:
There is my friend who is very weak and thin about 52 kg weight and he is one year older than me. I wanted to increase his weight up to 70 kg so I will recommend him to eat more nutritive food having large amount of proteins because proteins made muscles in the body. I suggest him to eat more food and exercise regularly to have a muscular body. The checklist is different from my checklist due to different goals. I wanted to lower my weight and increases the weight of my friend. My friend's energy needs are different from mine due to different goals to achieve.
Answer:
Males generally need more calories than females. Because men have an overall larger body in both height and weight, they need to consume more calories. For a male who is 20 years old, 5 feet and 10 inches, weighs 198 pounds, and has moderate physical activity, he should consume about 2,800 calories per day. That is about 1,000 calories more than my average caloric intake. To consume that many calories, he should eat 2 ½ cups of fruit, 3 ½ cups of vegetables, 7 ounces of protein, 3 cups of dairy, and 10 ounces of grains per day.

How gamete formation leads to genetic variation.
Answer:
The process that produces gametes is called meiosis. During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. ... At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
Answer:
Explanation:
During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

Imagine that fully functioning kidneys have been successfully created through bioengineering. What data analysis would measure the effectiveness of bioengineered organs in improving access to organ transplants among diverse groups of people, and what evidence would be needed to demonstrate that bioengineered organs have improved access
Answer:
The correct data analysis and evidence is:
Analysis: Compare the percentage of different ethnic groups who receive kidney transplants before and after bioengineered kidneys are available.
Evidence: A greater percentage of African Americans, Asians, and Pacific Islanders, and Hispanic/Latinos receive transplants after bioengineered kidneys are available compared to before
Explanation:
Bioengineered organs may be used to repair organs that have been destroyed. If the bioengineered organs are identical to the initial ones, transplantation rejection may be reduced.
So, to assess the effectiveness of organ donation adoption in people of various ethnicities, we should compare the percentage of people of various ethnicities receiving organ transplants before and after bioengineered organs became viable, and look for signs of a higher percentage of people of various ethnicities receiving organ transplantation after bioengineered organs became available.

Using examples where supportive, discuss the following statement, "From vaccinations and diagnostics, to explaining the root causes of many diseases, immunology is having a profound impact on life today"
Answer:
Yes.
Explanation:
Yes, immunology is having a profound impact on life today because this immunology provides information about the study of immune system. To find out the root cause of many disease, the study of immune system and its responses against many diseases are important in order to counter the infection. The immune system protects us from infection through various defense mechanism. If the immune system is not working properly, it can result in disease, such as autoimmunity, allergy and cancer etc.
Indicate whether the statements below are TRUE or FALSE.
1. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.
2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.
3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration.

Which statement correctly describes how the mitochondrial uncoupling agent valinomycin inhibits oxidative phosphorylation without collapsing the proton (H+) gradient across the inner mitochondrial membrane?
a. Valinomycin carries Kt into the mitochondrial matrix, reducing the electrical component of the electrochemical gradient across the inner mitochondrial membrane.
b. Valinomycin carries Ht into the mitochondrial matrix, decreasing the mitochondrial membrane potential without generating ATP.
c. Valinomycin is a complex I inhibitor that prevents NADH oxidation and the pumping of H+ into the intermembrane space.
d. Valinomycin is an ATP synthase inhibitor that prevents H+ from moving down its concentration gradient into the matrix.
Answer:
a. Valinomycin carries Kt into the mitochondrial matrix, reducing the electrical component of the electrochemical gradient across the inner mitochondrial membrane.
Explanation:
Oxidative phosphorylation is a process by which cells generate ATP (the energy coin of the cells) by coupling an electrochemical potential gradient across the inner mitochondrial membrane created by the electron transport chain to phosphorylation of ADP. Moreover, an ionophore is a molecule that reversibly binds ions. Ionophores are often involved in the movement of ions across the cell membrane. Valinomycin is an ionophore that mediates the transport of potassium (K+) ions down a concentration gradient, which is capable of disrupting the gradient across the membrane by modifying the K+ gradient. Valinomycin binds to K+ ions and enables them to pass more rapidly across the mitochondrial inner membrane, thereby neutralizing the excess of negative charge inside the mitochondrial matrix and thus slowing ATP synthesis.

In which numbered cells should he place pressure?
O 2, 4, and 5
O 1, 4, and 6
O2, 3, and 5
O 1, 3, and 6
The correct option is D.) 1, 3, and 6 because pressure is the changing factor in Gay-Lussac's Law, the constant factor in Boyle's Law, and the changing factor in Charles's Law.
Gay-Lussac's Law states that the pressure of a given quantity of gas held at constant volume is directly proportional to the Kelvin temperature which means the pressure of a gas increases as the temperature increases, and decreases as the temperature decreases.
Boyles Law states that the pressure of a gas is inversely proportional to its volume that means as the volume of a gas increases, the pressure of the gas decreases, and vice versa.
Charles's law is a basic physical law that states that the volume of a given amount of gas at a constant pressure is directly proportional to its absolute temperature. This means that when the temperature of a gas increases, its volume also increases, and vice versa.
