2) A pigment present in cell of epidermis dash
3) Force applied by machine dash
4) Nutrients dash
Answers
Answer:
1)Since the hands of a clock move accordingly at regular time intervals, they are known to exhibit periodic motion. Since the clock hands move in a circular direction, they are said to be in circular or rotational motion. Therefore, the clock hands are said to be in a periodic motion and circular or rotational motion.
2)The amount and distribution of melanin pigment in the epidermis is the main reason for variation in skin color in Homo sapiens. Melanin is found in the small melanosomes, particles formed in melanocytes from where they are transferred to the surrounding keratinocytes.
3)Effort' is the force applied on a machine to make it work.
4)The main aim of the DASH diet is to reduce high blood pressure. A person will eat fruits, vegetables, whole grain, low-fat dairy foods, poultry, fish, nuts, and beans, but they will limit their intake of red meat, fat, sugar, and salt.
Answer:
1) Motion of hands of clock is known as Periodic motion.
2) A pigment present in cell of epidermis is known as Melanin.
3) Force applied by machine is known as Resistance.
4) Nutrients are the compounds in food that provide us with energy that facilitates repair and growth and helps to carry out different life processes.
Explanation:
1) Motion of hands of clock is known as Periodic motion.
Periodic motion:
- Periodic motion is the term used in physics to describe a motion that repeats itself at regular intervals. The hands of a clock are known to display periodic motion because they move in accordance with regular time intervals.
- The clock hands are considered to be in circular or rotational motion because they move in a round pattern.
- As a result, the motion of the clock hands is described as periodic and circular or rotational.
- The pendulum of pendulum clocks swings back and forth from one end to the other. Harmonic motion is what this is because the top spins around its own axis, it is rotating.
2) A pigment present in cell of epidermis is known as Melanin.
Melanin:
- Melanin is a pigment found in the epidermal cells of the skin.
- The melanocytes in the epidermal layer produce melanin.
- The proportion determines the skin's tone; a higher percentage results in darker skin, whilst a smaller percentage results in lighter skin.
- Additionally, it shields the skin from the Sun's UV rays.
3) Force applied by machine is known as Resistance.
Resistance:
- The obstruction to current flow in an electrical circuit is measured by resistance.
- The Greek letter omega () represents the unit of measurement for resistance, known as ohms. Georg Simon Ohm (1784–1854), a German physicist who investigated the connection between voltage, current, and resistance, is the name given to the unit of resistance. Ohm's Law is attributed to him as its creator.
4) Nutrients:
- Nutrients are the compounds in food that provide us with energy that facilitates repair and growth and helps to carry out different life processes.
Important Nutrients in Food:
- There are some nutrients that the body is unable to produce on its own and must be obtained from diet.
- These are essential for the body's healthy operation. The following are examples of significant nutrients.
- Proteins, Carbohydrates, Calcium, Cholesterol, Fats, Iron, Sodium.
Functions of Nutrients:
- They are the body's primary source of energy.
- They support the development and repair of bodily tissues.
- Increases the absorption of vitamins that are fat-soluble and aids in the production of collagen.
- It gives the blood vessels, bones, and ligaments the right structure.
- They also aid in preserving the body's equilibrium.
