How fast you are moving is

How fast you are moving in which direction is

Change of speed or direction is

The tendency of an object to remain still or moving at a constant speed is [blank_start]intertia[blank_end]

A heavy and light object are dropped from the same height. Which object hits the floor first?

The formula for speed is:

You apply force on two objects. The second object is 4 times heavier. How does the second object accelerate compared to the first?

A force accelerates a mass of 2kg with an acceleration. If the same force is applied to mass 1kg, then the acceleration will be

Difference Between Mass and Weight Mass is the amount of [blank_start]matter[blank_end]. It does depend on [blank_start]gravity[blank_end]. Weight is a [blank_start]force[blank_end]. It is your mass times [blank_start]gravity[blank_end]. It is measures in [blank_start]Newtons[blank_end] (N).

What is the mass number of an atom?

The atomic number of an atom is the number of [blank_start]protons[blank_end].

If the mass of C atom is 12 and O atom is 16, then the mass of carbon dioxide is [blank_start]44[blank_end].

-The charge of a proton is [blank_start]+1[blank_end] and its mass is [blank_start]1[blank_end] -The charge of a neutron is [blank_start]0[blank_end] and its mass is [blank_start]1[blank_end] -The charge on an electron is [blank_start]-1[blank_end] and its mass is [blank_start]0[blank_end]

The mass number of aluminium is [blank_start]27[blank_end] The atomic number of aluminium is [blank_start]13[blank_end] The electron configuration of aluminium is [blank_start]2, 8, 3[blank_end]

Most of the volume of the atom is taken up by

What is the name for similar atoms that have a different numbers of neutrons?

What is the correct statement to describe the difference between a sex cell and a normal cell?

Genes are only found in some cells of the body

A gene is a small piece of DNA

Genes are found in the nucleus

There are two different genes (alleles) for each characteristic

The father of genetics is [blank_start]Gregor Mendel[blank_end]

Phenotype is the appearance an individual has for a particular characteristic

The last pair of chromosomes out of the [blank_start]23[blank_end] pairs found in human cells, are [blank_start]sex[blank_end] chromosomes. Males have the sex chromosomes [blank_start]XY[blank_end] and females have [blank_start]XX[blank_end]

Genes are composed of [blank_start]DNA[blank_end]

The scientists who discovered the shape of DNA to be a double helix were [blank_start]Crick[blank_end] and [blank_start]Watson[blank_end] (In alphabetical order).

In biological terms, the organism that is most successful within its population is one that

The theory of [blank_start]evolution[blank_end] states that [blank_start]organisms[blank_end] come from common [blank_start]ancestors[blank_end], small changes over time result in diversity of [blank_start]life[blank_end]. Word Bank: organisms, diversity, evolution, ancestors

Which of the following statements about mutations is false

According to Darwin's theory of evolution:

Which of the following statements is true

The process of promoting certain traits by breeding members with those traits is [blank_start]artificial[blank_end] selection

The two main components of natural selection are [blank_start]inheritance[blank_end] and [blank_start]variation[blank_end] (alphabetical)

Newton's First Law states that an object will remain at [blank_start]rest[blank_end] or in uniform motion in a straight line unless acted upon by an [blank_start]external force[blank_end] Newton's Second Law states that [blank_start]acceleration[blank_end] is produced when a [blank_start]force[blank_end] acts on a [blank_start]mass[blank_end]. The greater the mass (of the object being accelerated) the greater the amount of [blank_start]force[blank_end] needed (to accelerate the object). The formula created from this was [blank_start]F=MA[blank_end] Newton's third law states that for every [blank_start]action[blank_end], there is an [blank_start]equal[blank_end] and opposite [blank_start]reaction[blank_end]

There are [blank_start]forty six[blank_end] chromosomes in a normal call for people

DNA stands for [blank_start]deoxyribonucleic[blank_end] acid
