After each bar press, a laboratory rat receives electric stimulation to its brain. The rate of bar pressing increases. This is an example of operant conditioning given by Skinner.
What do you mean by electric stimulation?Electric stimulation may be defined as the process that uses the device to transmit gentle electrical pulses via the skin.
Operant conditioning is associated with the hit and trial conditioning method which was proposed by B.F Skinner. This experiment falls in association with the behavior and stimuli of an organism or model.
Therefore, after each bar press, a laboratory rat receives electric stimulation to its brain. The rate of bar pressing increases. This is an example of operant conditioning.

The illustration below shows the wing structure of an insect. Line-drawing of insect wing, showing outline of wing and pattern of veins. The wing is narrow where it attaches to the body, gets wider, then gets narrow again, and has a rounded tip. Which of the following animals will most likely have a wing structure that is very similar to this insect’s wing structure?
A. An animal from the same class
B. An animal from the same genus
C. An animal from the same phylum
D. An animal from the same kingdom
An animal from the same class as the insect will most likely have a wing structure that is very similar to the insect's wing structure. Therefore, the correct statement is option A.
What are insect's wings consisting of?The class here is Insecta, which includes all insects. Insects are a diverse group of organisms having unique features, including wings. Insect wings consists of a thin, membranous layer supported by a network of veins.
The veins provide structure and strength to the wing and is a characteristic of the class Insecta. However, there is a large variation in insect wings, shapes, sizes, and patterns of veins, the basic structure is the same.
Insect wings are narrow where they attach to the body, get wider toward the middle of the wing, and then get narrow again at the tip, often with a rounded or pointed shape. This general shape and vein pattern is common to all insects with wings.
Therefore, the insects, which belong to the same class Insecta, will have similar wing structures to the insect in the illustration.

Cross a female with normal color vision, but whose father was colorblind, with a man who has colorblindness. Tell the expected phenotypic ratio of the offspring
If a female with normal colour vision, but her father was colour blind crosses with the man who has colourblindness, the phenotypic ratio of the offspring is 50%.
What is Colorblindness?Colour blindness is linked to the X-chromosome defect. It is a condition in which a person is unable to see the colors or differences in colours or its abilities decreased. For example, he was unable to distinguish between the colour of traffic lights, colour of fruits or choosing clothes.
Colour blindness is to be present on all X chromosome within the individual have to be affected; so the man has only one X-chromosome and women have two, the chances of colour blindness is much more higher in men as compared to women.
In the above example due to genetic inheritance of the mother from her father, the chances of colour blindness in their child is 50% because each parent is a carrier having X chromosome.
In this case chances of inheriting colour blind X chromosome would be double as likely for female child because both mother and father are the carriers of X chromosome of colour blindness.
Thus, if a female with normal colour vision, but her father was colour blind crosses with the man who has colourblindness, the phenotypic ratio of the offspring is 50%.

Answer:
Carbon Dioxide is a gas it is always part of the atmosphere. However Carbon Dioxide gas can be removed and returned to the atmosphere.
Explanation:
Plants use Carbon Dioxide as one of the two main reactants in the process of photosynthesis. Photosynthesis removes Carbon Dioxide from the atmosphere turning the Carbon into Carbohydrates, such as cellulose found in wood.
Cellular Respiration, burning coal, wood, gasoline, turn the Carbon-based molecules back into Carbon Dioxide and water. These Oxidation reactions return the Carbon Dioxide to the atmosphere
