Answer:
Option A
Explanation:
In this case, there are two varieties of horses: Domestic horses that are raised and bred by humans and Wild horses that lives in the wild. The issue of varieties in coat colour of domestic horses can be explained as what occured by selective breeding, also known as artificial selection which is a technique by which humans develop new offsprings with desirable and suitable characteristics. These breeders select two parents that possess beneficial phenotypic traits to mate, producing offsprings with those desired traits such as strength and also for coat colour as stated.

The particles in a gas move quickly in all directions, but they do not get far before they bump into each other or the walls of their container.
Answer:
Yes, different cell types also have special duties, like building skin or bone, pumping out hormones, or making anti-bodies.
Explanation:
Cell is the basis structural and functional unit of a living organism. The body of a human is composed of trillions of cells that are organized in around 200 types of cells.
<u>A tissue is simply a group of specific kind of cell that have a specific role.</u>
- For example: The nervous system contains cells called neurons that have ability to transmit message from one place to another and allow us to respond to any environmental stimuli, such as heat, cold, danger etc.
- Skin cell is composed of cells that have a role in protecting the body against the attack of harmful microbes. They also protect have role in building new skin cells and adding the protection to our body.
- Blood cells have a role in providing us immunity (for example white blood cells) therefore, make us better able to protect ourselves from danger of diseases.
- Muscle cells help us in moving our organs as well as allowing the whole movement from one place to another.
Thus we see that different types of cells have special functions and all these different cells coordinate with each other to make an organized and functioning body of a living organism.

Weathering is the process by which rocks are broken down into smaller particles as a result of physical and chemical changes that are occurring in them. There are three major types of weathering these are: physical, chemical and biological weathering.
For the question given above, the type of weathering that is occurring in the picture of the given rock is PHYSICAL WEATHERING.
Physical weathering is the type of weathering in which the affected rock is changed in size and shape by means of some agents. The broken particles are usually of the same composition as the parent rock. The agents of physical weathering include: ice, plant roots, animal activities, abrasion and exfoliation. Physically weathered rocks are usually round in shape as a result of the abrasion process which they have undergone.<span />
