Answers

A baby is bitten by a dog and then is afraid of all small animals. this is an example of stimulus generalisation.

The tendency for a new stimulus to elicit a new response or behavior that was prompted by a previous stimulus is known as stimulus generalization. Because of the baby's contact with the one dog that bit him/her in this case, the newborn is now terrified of all dogs.

The capacity to act in a new environment in a way that has been honed in previous similar circumstances is known as stimulus generalization. How to determine which elements of the learning scenarios should be generalized is the issue. Both symbolic and associationist representations find this to be puzzling. Conversely, the stimulus is represented as being categorized along a specific dimension or domain when conceptual spaces are used.

The pesticide treadmill A. provides exercise for many farmers. B. results in a reduction in the amount of pesticides used. C. describes the need to use increasing higher dose of pesticides. D. is an excellent way to overcome genetic resistance in pests.

Answers

The pesticide treadmill describes the need to use increasing higher doses of pesticides (option C)

What is the pesticide treadmill?

The pesticide treadmill is a term used to refer to the phenomenon where pests and diseases that were previously under control become more resistant to pesticides with repeated use. To deal with the resistant pests, more pesticides are used at increasingly higher doses to get the same effect.

The pesticide treadmill is a self-defeating cycle. It's a self-perpetuating pattern in which farmers are forced to use increasing amounts of pesticides to keep pests under control. This is because pests evolve to become resistant to the pesticides used to control them over time. The pesticide treadmill also leads to negative environmental and public health consequences.

Thus, the correct option is C.

As a result of left ventricular hypertrophy, it may reveal thicker heart muscle tissue and heart valve issues. Treatment for left ventricular hypertrophy depends on its underlying cause. It can include having surgery, receiving a catheter, or taking medication. Controlling conditions that cause high blood pressure is essential. Medication is used to treat the signs and symptoms of left ventricular hypertrophy, and the consequences are also prevented. Blood pressure drugs may help to prevent or lessen the thickening of the heart muscle. To treat the left ventricular hypertrophy caused by aortic valve stenosis, a catheter method or surgery to fix or replace the valve may be required.

What is an element?

An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all in  solid state at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons which are present  in the nucleus are  the defining property of an element and are  related to the atomic number.All atoms with same atomic number are atoms of same element.Different elements combine to form  substances which are called as compounds.

Which of the cranial nerves below is purely sensory?.

Answers

The cranial nerve that is purely sensory is the olfactory nerve (cranial nerve I). The answer is the olfactory nerve. This nerve is responsible for the sense of smell and is unique in that it does not have any motor functions.

It contains sensory neurons that detect odor molecules in the air and send signals to the brain for interpretation. An explanation for this is that the olfactory nerve is composed of specialized nerve cells called olfactory receptor neurons which are located in the nasal cavity. When an odor molecule binds to a receptor, it triggers an electrical signal that is transmitted to the olfactory bulb in the brain. This information is then processed and interpreted to identify the specific odor.

The Olfactory nerve is responsible for transmitting sensory information related to smell from the nasal cavity to the brain. It is a purely sensory nerve, as it does not have any motor functions.

The Optic nerve (Cranial Nerve II) is also a purely sensory nerve, responsible for transmitting visual information from the retina to the brain.

In summary, both the Olfactory (Cranial Nerve I) and Optic (Cranial Nerve II) nerves are purely sensory nerves, with the former responsible for smell and the latter responsible for vision.
