Answer:

The generated sound wave will not be able to reflect off of the object.

Explanation:

Ultrasound may be defined as the sound waves that has the frequency range larger than 20,000 Hz. This sound range is inaudible to human ears but can be detected by the animals like bats.

Ultrasound is used in the medical application as well. The kidney stones can be detected by using the ultrasound. The rays can be detected back if there is any chances of hurdles or possibility of stones in the kidney. If the kidney is normal no ultrasound waves will be deflected back.

Thus, the correct answer is option (A).

If the machine is working properly then that rules out 2, 3 and 4 as they are all technical problems and therefore it must be A there waves don't reflect of the stone properly and therefore no image is formed

Hope that helps

Explanation: Catabolic reactions are exothermic meaning they release alot of energy and electrons, whereas anabolic reactions are endothermic using up alot of energy for production and storage. Breaking down glucose to produce ATP is an example of a catabolic reaction. Using fatty acids and lipids to make adipose tissues is an example of an anabolic reaction, breaking down adipocytes for production of heat and ketone bodies is catabolic.

Cheranita is experiencing the first stage of the general adaptation syndrome. an environmental stressor has triggered a process

aniked [119]

The correct answer is hypothalamus; autonomic.
The General Adaptation Syndrome (GAS) is the sequence of physiological processes which occur when we are exposed to a stressor. GAS is comprised of three stages which are the alarm, the resistance, and the exhaustion phase.

The first stage, known as the alarm phase, involves the fight or flight response, which is the natural reaction when under threat. A distress signal is sent by the amygdala to the hypothalamus, which in turn activates the sympathetic branch of the autonomous nervous system.
