Science is one of the most existing subjects for you to take up and offers a lot of answers regarding the universe as a whole. If you are looking for some science questions to jog your memory the one below is perfect for you. Give it a shot and keep an eye out for more.

• 1.

### What is the function of cell membrane ?

• A.

Allow entry or exit substance from the cell

• B.

Maintains the shape of the cell

• C.

Stores dissolves materials

• D.

Has chlorophyll

A. Allow entry or exit substance from the cell
Explanation
The cell membrane functions as a selectively permeable barrier, allowing certain substances to enter or exit the cell while preventing others from doing so. It controls the movement of molecules and ions in and out of the cell, maintaining homeostasis and regulating the internal environment. This enables the cell to take in essential nutrients and eliminate waste products, ensuring its survival and proper functioning. The other options mentioned, such as maintaining the shape of the cell, storing dissolved materials, and having chlorophyll, are not accurate descriptions of the primary function of the cell membrane.

### SI unit for weight is

• A.

Kilogram (kg)

• B.

Gram (g)

• C.

Newton (N)

• D.

Centimetre (cm)

C. Newton (N)
Explanation
The SI unit for weight is newton (N) because weight is a force and the newton is the unit of force in the International System of Units (SI). The newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. Therefore, weight is measured in newtons as it represents the force exerted by an object due to gravity.

### Which of the following is natural phenomenon ?

• A.

Forestry

• B.

Destruction

• C.

Flower blossoming

• D.

Forest reservation

C. Flower blossoming
Explanation
Flower blossoming is a natural phenomenon because it is a process that occurs in nature without any human intervention. It is a part of the natural life cycle of plants, where flowers bloom and release pollens for reproduction. This process is influenced by factors such as sunlight, temperature, and seasonal changes, which are all natural occurrences. On the other hand, forestry, destruction, and forest reservation are all human activities or interventions in the natural environment.

### which of the following is the prefix value of milli ?

• A.

0.01

• B.

0.0001

• C.

0.001

• D.

0.1

C. 0.001
Explanation
The prefix value of milli is 0.001. The prefix "milli" represents one thousandth of a unit. Therefore, 0.001 is the correct answer as it represents the value of milli.

### When the sea breeze occur ?

• A.

Night

• B.

Day

• C.

Evening

• D.

Dusk

B. Day
Explanation
Sea breeze occurs during the day. This is because during the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer and rises, creating a low-pressure area. The cooler air from the sea then moves in to fill this void, creating a breeze that blows from the sea towards the land. This phenomenon is most pronounced during the afternoon when the temperature difference between the land and sea is at its peak.

• 6.

### ................ is the distance between two points.

length
Explanation
The term "length" refers to the measurement of the distance between two points. It is a scalar quantity that represents the extent of an object or the interval between two locations. In various contexts, length can be used to describe the size, dimension, or extent of an object or distance.

### What is/are the instruments for measuring mass ?

• A.

Compression balance

• B.

Electronic balance

• C.

Lever balance

• D.

Double beam balance

• E.

Spring balance

• F.

Beam balance

• G.

Triple beam balance

B. Electronic balance
C. Lever balance
D. Double beam balance
F. Beam balance
G. Triple beam balance
Explanation
The instruments for measuring mass include electronic balance, lever balance, double beam balance, beam balance, and triple beam balance. These instruments are commonly used in laboratories and scientific settings to accurately measure the mass of objects. Electronic balance uses electronic sensors to measure the mass, while lever balance, double beam balance, beam balance, and triple beam balance use a system of levers and beams to achieve balance and determine the mass. These instruments provide precise measurements and are essential tools in various scientific experiments and research.

### Definition of weight

• A.

The amount of matter in an object

• B.

The measure of the Earth's gravity force acts on an object

B. The measure of the Earth's gravity force acts on an object
Explanation
The correct answer is "the measure of the Earth's gravity force acts on an object." This definition of weight refers to the force exerted on an object due to the gravitational pull of the Earth. Weight is a measure of the amount of gravitational force acting on an object, and it can vary depending on the strength of the gravitational field. It is different from mass, which is a measure of the amount of matter in an object and remains constant regardless of the gravitational field.

### Effects of carbon monoxide.

• A.

Acid rain

• B.

Resulting in death

• C.

Smog

• D.

Global warming

B. Resulting in death
Explanation
Carbon monoxide is a toxic gas that is released from the incomplete combustion of fossil fuels. When inhaled, it binds to hemoglobin in the blood, reducing its ability to transport oxygen. This can lead to oxygen deprivation in the body, causing tissue damage and, in severe cases, death. Therefore, the presence of carbon monoxide can result in death.
