O True
O False​

Answers

Answer 1

Answer:

false

Explanation:

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

Answers

Answer:

B. Bulimia

Explanation:

See below for a description of each case:

Anorexia (also known as Anorexia nervosa) is an eating disorder characterized by abnormally low body weight. It's similar to the starving of oneself to achieve lower weight, but this is unhealthy. It's very common (more than 3 million cases per year in US) and is treatable. This can last for several months or years and is more common in females from ages 18–35.

Some symptoms include:

Extreme weight loss

Thin appearance  

Fatigue and insomnia  

Bluish discoloration of the fingers

Hair that thins, breaks or falls out  

Amenorrhea (absence of menstruation)  

Dry or yellowish skin  

Dehydration

Bulimia (also known as Bulimia nervosa) is an eating disorder characterized by binge eating, followed by methods to avoid weight gain (ie. vomiting). It's very common (more than 3 million cases per year in US) and is treatable.  It can last several years or be lifelong and are more common in females from ages 18–35.

Some symptoms include:

Binge eating

Forceful vomiting

Long-term fear of gaining weight  

Overuse of laxatives or diuretics

Use of supplements or herbs for weight loss

Excessive exercises

Stained teeth (from stomach acid)

Obesity is a condition characterized by abnormal or excessive fat accumulation. It's extremely common (more than 3 million cases per year in US) but is treatable. It can last several years or be lifelong. Family history may increase likelihood for some types.

Some symptoms include:

Above average body weight  

Sleep apnea- a condition in which breathing is irregular and periodically stops during sleep  

Skin problems caused by moisture that accumulates in the folds of your skin  

Osteoarthritis in weight-bearing joints, especially the knees

Parkinson's disease is a chronic and progressive movement disorder, meaning it weakens the control of movements of the body over time. It's fairly common (more than 200,000 cases per year in US). There are treatments to manage the condition but there is no known cure. This can last several years or be lifelong. It's more common in 60+ years old males.

Some symptoms include:

Tremors, trembling of hands, arms, legs, jaw and face

Stiffness of the arms, legs and trunk

Slowness of movement

Poor balance and coordination

Speech difficulty

What do you mean by Constellations?

Constellations may be defined as clusters of stars that form a recognizable pattern and were imagined in order to construct noticeable and apparent configurations of objects or creatures in the sky, especially at night.

These groups of stars are also present in the day but they are not perceived due to the extremely high light of the sun. So, they form patterns in the night sky. These groups of stars are not specifically present as they are distributed randomly and can form new images.

Therefore, the correct options for this question are A, B, and D.

Why do the temperatures change over the months?
O A. Because the Moon is tilted on its axis, it reflects more sunlight on Earth during different times of Earth's yearly orbit.
B. Because the Sun is tilted on its axis, parts of Earth get more sunlight during different times of Earth's yearly orbit.
O C. Because Earth is tilted on its axis, the stars reflect more light during different times of the Earth's yearly orbit.
D. Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit.

Answers

Answer:

Answer

Explanation:

B because the more the sun is titled the more heat=different season.

Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit. As Earth orbits around the Sun, its axis is tilted at an angle of about 23.5 degrees. Hence the correct option is D.

Why do the temperatures change over the months?

The temperatures change over the months primarily because of Earth's axial tilt. As the Earth rotates around the sun, the angle at which sunlight hits different parts of the Earth changes.

This is because the Earth's axis is tilted about 23.5 degrees relative to its orbit around the sun. When a particular hemisphere is tilted toward the sun, it receives more direct sunlight, resulting in warmer temperatures.

Conversely, when that hemisphere is tilted away from the sun, it receives less direct sunlight, resulting in cooler temperatures. This cycle repeats itself annually, causing changes in temperatures over the months.

Hence the correct option is D.
