Answer: Positive; Negative
Explanation:
As you might expect, in both the individual and published results, positive word pairings had the highest pleasantness rating, while the lowest pleasantness ratings were given to the negative word pairings, with the remaining word type falling between these two extremes, in terms of perceived pleasantness of associated syllables.
No context is provided however this should be the right answer. Positive word pairings elicit a happier feeling in humans so they will have a higher pleasantness rating. Words such as money and happy for instance have very high pleasantness ratings.
Negative word pairings on the other hand will have the lowest pleasantness ratings as they have more sombre connotations.

Answer:
The correct answer is investigation
Explanation:
Investigation here means scientific investigation or experiment. In scientific process, when a new phenomenon is observed, an hypothesis is made in an attempt to explain the concept behind the observation. An experiment/investigation is then embarked upon to determine if the hypothesis provides the right answer or perspective to this observation. The outcome/conclusion of this experiment after repeated trials is referred to as theory while a theory tested over a long period of time is a law.
However, if the experiment doesn't confirm the hypothesis, new questions or hypothesis will have to be proffered

(0,-8) and (3,-2) find the distance between each pair of points
Answer:
The distance between the points is 6.71 unit
Explanation:
Given points;
(0,-8) and (3,-2)
The distance between the points is given by;
[tex]d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]
where;
x₁ = 0, x₂ = 3
y₁ = -8, y₂ = -2
[tex]d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d = \sqrt{(3-0)^2 + (-2-(-8))^2} \\\\d = \sqrt{(3^2) \ + (-2+8)^2}\\\\ d = \sqrt{3^2 +6^2 } \\\\d = \sqrt{45} \\\\d = 6.71 \ unit[/tex]
Therefore, the distance between the points is 6.71 unit

Answer:
Enzymes are produced through protein synthesis within cells. Once formed, the location of enzymes secreted varies. Enzymes may remain within the cell. An example of an enzyme that does this is DNA polymerase that helps to form new DNA. Enzymes may also become embedded in the plasma membrane. The enzyme lactase does this. It can be found in the plasma membranes of small intestine cells. As a final option, some enzymes will be secreted from the cell and used by other cells. An example of this can be seen with pancreatic production of pancreatic amylase. Once it is released from the pancreas, it participates in starch digestion in the small intestine.
Explanation:
Enzymes are a special type of protein that have the important function to catalyze chemical reactions - this means that the lack of a certain enzyme will result in an important chemical reaction not happening, or happening at a much lower rate. These chemical reactions can be anabolic (meaning the creation -synthesis- of a molecule) or catabolic (which refers to the destruction -degradation- of a molecule).
For example, like the paragraph above explained, enzymes in the digestive tract have the task to convert the food that we ingest into smaller particles that can be absorbed by our intestines and used as nutrients. If one of these enzymes were to be absent, that specific nutrient wouldn't be properly digested - as it happens in people that are lactose intolerant (they lack the enzyme lactase, so they can't digest lactose, the sugar present in dairy products).
Two students are testing the amount of fertilizer that would best promote the growth of strawberries in a garden. Which of the following is a controlled variable?
amount of fertilizer
growth of the strawberries
number of leaves
type of soil
A controlled variable is a variable that is kept constant or unchanged throughout an experiment. In this case, the controlled variable is: Type of soil, option (D).
What is a controlled variable?A controlled variable is a variable that is kept constant or unchanged throughout an experiment. It is also called a constant or standard variable. The purpose of a controlled variable is to eliminate the possibility that changes in the experimental results are due to changes in any other variable except the one being tested.
In an experiment, there are usually one or more independent variables, which are manipulated or changed to observe their effect on the dependent variable, which is the variable being measured. The controlled variable is kept the same to prevent it from influencing the experimental outcome. By keeping the controlled variable constant, the experimenter can be confident that any observed changes in the dependent variable are due to changes in the independent variable, not the controlled variable.

Help right answer please ??A fertilized egg receives 50% of its chromosomes from a sperm and 50% from the egg. Which process ensures that the sperm and egg contain only 50% of the chromosomes of an organism?
fertilization
meiosis
mitosis
mutation
The process that ensures that sperm and egg contain only 50% of the chromosomes of an organism is meiosis. The correct option is B.
What is meiosis?Meiosis is a type of cell division that occurs in reproducing organisms and results in a reduction in the number of chromosomes in gametes. Human body cells are diploid, with two sets of chromosomes (one from each parent).
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is necessary for the production of egg and sperm cells for reproduction.
A cell with a single set of chromosomes is referred to as haploid. The term haploid can also refer to the number of chromosomes in gametes, which are egg or sperm cells.
Meiosis occurs in primordial germ cells, which are distinct from the body's normal somatic cells and are designated for reproduction.
Thus, the correct option is B.

Sickle cell anemia is a hereditary medical condition that affects red blood cells and is thought to protect against malaria, a debilitating parasitic infection of the liver and the blood. This protection would explain why the sickle-cell trait is found in people who originally came from Africa, where malaria is widespread. A landmark study in Africa tested children for the sickle-cell trait and for malaria infection. In all, 30% of the children had the sickle-cell trait, and 8.5% of the children had both the sickle-cell trait and malaria. Overall, 34.5% of the children had malaria.
Answer:
The answer is below
Explanation:
The complete question is:
(a) What is the probability that a child has either malaria or sickle-cell? Please use 3 decimal places.
(b) What is the probability that a child has neither malaria nor sickle-cell? Please use 3 decimal places.
(c) What is the probability that a child has malaria given that the child has the sickle-cell trait? Please use 3 decimal places.
(d) What is the probability that a child has malaria given that the child does not have the sickle-cell trait? Please use 3 decimal places.
(e) Are the events sickle-cell trait and malaria independent? What might that tell you about the relationship between sickle-cell and malaria
Answer:
Let S represent sickle cell anemia and M represent malaria. Hence, Given that:
P(S) = 30% = 0.3, P(S ∩ M) = 8.5% = 0.085, P(M) = 34.5% = 0.345
a) P(that a child has either malaria or sickle-cell) = P(S ∪ M) = P(M) + P(S) - P(S ∩ M)
P(S ∪ M) = P(M) + P(S) - P(S ∩ M) = 0.345 + 0.3 - 0.085 = 0.56 = 56%
b) P(that a child has neither malaria nor sickle-cell) = P(S ∪ M)' = 1 - P(S ∪ M) = 1 - 0.56 = 0.44 = 44%
c) P(child has malaria given that the child has the sickle-cell trait) = P(M / S)
From conditional probability, P(M / S) = P(M ∩ S) / P(S) = 0.085/0.3 = 0.283 = 28.3%
d) P(S') = 1 - P(S) = 1 - 0.3 = 0.7
P(M ∩ S') = P(M) - P(S ∩ M) = 0.345 - 0.085 = 0.26
P(child has malaria given that the child does not have sickle-cell trait) = P(M / S')
From conditional probability, P(M / S') = P(M ∩ S') / P(S') = 0.26/0.7 = 0.371 = 37.1%
e) Two events are independent if the occurrence of one event does not affect the other event. Malaria and sickle cell traits are not independent events because there is evidence of a biological link between the two conditions

C. Osteoclasts resorb dead portions of the new bony area, and compact bone replaces spongy bone.
D. Osteoprogenitor cells differentiate into osteoblasts and produce spongy bone.
E. Phagocytes and osteoclasts begin to remove dead and damaged tissue.
A) A,B,E,C,D.B) A,E,B,D,C.C) E,A,B,D,C.D) A,E,D,B,C.
Answer:
The correct answer is: C) E,A,B,D,C.
Explanation:
Bone fractures occur when a trauma generated a breach in the continuity of the bone. When a bone fractures, a process called secondary healing starts.
The first step in fracture repair is the removal of dead tissues - this is done by specialized cells called phagocytes and osteoclasts, that proceed by "eating" the damaged tissues.
Next, a hematoma forms because the blood vessels surrounding the fractured bone were ruptured. This hematoma clots and forms the temporary frame for the process of healing that is happening.
Mesenchymal stem cells migrate to the area and begin to differentiate into fibroblasts and chondroblasts, which is important for the production of fibrocartilage, a tissue that will connect the ends of the broken bone.
Then, osteoprogenitor cells differentiate into osteoblasts, which are the cells that synthesize bone tissue. These osteoblasts will produce spongy bone. The newly-formed fibrocartilage tissue becomes calcified.
Finally, osteoclasts begin with a process called resorption, which consists of resorbing the dead portions of the new bony area. This resorption is coupled with osteoblasts' bone synthesis. These two processes that occur together are fundamental for bone remodeling, which will end up with the spongy bone being transformed into compact bone.
