Answer:

B

Explanation:

We know that life began at least 3.5 billion years ago, because that is the age of the oldest rocks with fossil evidence of life on earth.

The correction that is needed to be made is that rocks do have specific chemical compositions and minerals do as well. The correct option is C.

Minerals are elements found on the Earth and also in foods which our bodies require for normal development and function.

Minerals generally have certain specific chemical compositions, but it is not in case of rocks.

Thus, the correct option is C.

Explanation:

this is to slow down the movement of the object sliding on a surface

Answer:

more glucose and change to a blacky-purple colour

Explanation:

The substance will show net movement out of the cell more glucose and change to a black to purple color.

The organisms which are made up of single cell has been known as the unicellular organisms and in the unicellular organism all the life processes takes place in a single cell. Amoeba has been known as an unicellular organism in which all the activities has to be related to the life carried out in a single cell.

Multicellular organisms are made up of the eukaryotic cell and the eukaryotic cell is consist of different cell organelles to carry out different functions in the cell. The multicellular organisms perform different life process in different cells because they have specific cell for specific function.

The unicellular organisms are made of one cell and carry out the processes of life as a single cell and the multicellular organisms are made up of two or more cells that have specific functions to contribute to the life processes.

Therefore, The substance will show net movement out of the cell more glucose and change to a black to purple color.

Explanation:

b  Each structure is a gene

A manual which contains all the instructions for how to build a variety of structures using a set of interlocking bricks, in this model the manual is a chromosome. Thus, the correct option is C.

The chromosomes are the building blocks of the genetic code. A manual contains all the instructions regarding how to build blocks or proteins in case of body of an organism and is also used to make models for genetic information.

At the functional level of genes, DNA contains all instruction manuals that describes the cells information. These genes are transferred during the process of fertilization and are passed on to the offspring.

Therefore, the correct option is C.

Answer:

D

Explanation:

The gene for dominant fur is dominant over white fur. The relationship between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent.

One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.

Dominant describes the relationship between two genetic variants. If one is in charge, the other must be subordinate. Then it is referred to as recessive.

A dominant gene, or dominant form of a gene, is a specific variant of a gene that expresses itself more powerfully on its own than any other version of the gene that the individual is carrying—in this example, the recessive—for a variety of reasons.

Therefore, The gene for dominant fur is dominant over white fur. The relationship between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent.

Answer:

The answer is A.

Explanation:

Answer:

The Coriolis effect acting on these currents causes northern hemisphere gyres to move in a clockwise direction and southern hemisphere gyres to move in a counterclockwise direction.

Explanation:

The Coriolis effect does the impact on the Gulf stream and the Brazil Current by turning the Gulf Stream towards northwest and Brazil Current northeast. Thus, the correct option is B.

The Coriolis effect results in bending the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form the circular patterns. The direction in which they spin depends upon the hemisphere in which they are present.

Coriolis Effect is named after the French mathematician and physicist Gaspard-Gustave de Coriolis. It affects the weather patterns of an area, it affects the ocean currents, and it also affects air quality.

Therefore, the correct option is B.

Answer:

Inertia- the tendency of an object to resist a change in velocity

Explanation:

Say a car was going at 65 MPH, but suddenly stopped. For all of the people in that car, their bodies would keep moving forward at 65 MPH until stopped by an equal force (say, the thing right in front of each person) The seatbelt is there to protect you from your own inertia.

Answer:

inertia is the constant state of movement so seatbelts stop that when you stop the car.
