way plain for others to follow them. For one hundred and
seventy years, ever since the first American Lincoln came
from England to Massachusetts in 1638, they had been
moving slowly westward
Explanation:
D. Provision of fresh water is a direct value of biodiversity.
Direct values of biodiversity refer to biological resources that give immediate satisfaction or enjoyment.
Two types of direct values of biodiversity are Consumptive use and productive use.
Fresh water is consumptive use. It is a direct value because we can access fresh water immediate from nature without it going through the market. Other examples of direct value for consumptive use are firewood, fodder and meat.
The biogeochemical cycle has to do with the cycle of nutrients and elements in nature.
<h3>What is the biogeochemical cycle?</h3>
The biogeochemical cycle has to do with the cycle of nutrients and elements in nature; they include the water cycle, carbon cycle, and nitrogen cycle.
The water cycle begins with the evaporation of surface water which is then condensed in the cloud and falls as rain.
The carbon cycle involves the combustion of fossil fuels, the calcification of shells of animals as well as the decay of organisms to release gaseous CO2.
The nitrogen cycle involves the nitrogen content of living things that is returned during decay to the earth as well the fixation of nitrogen by bacteria and also nitrification.

Answer:
The correct answer is OPTION C (Circumduction)
Explanation:
Circumduction is motions without clear opposites of the part of the body, an example is rotating the hand from the wrist. The answer is circumduction because this type of movement ensures the distal end of a bone moves in a circle while the proximal end remains relatively stable is particularly found in bones where the movements of the joints are opposite to each other example is the ball and socket joint movement. For circumduction to take place, the degree of distance between two bones of the body has to be decreased and sometimes straightened to increase the level of movement or motion produced, there must be a movement towards the middle of the body and sometimes joint movement away from the middle of the body. All these movements are in order.
Adaptations help the survival of a species as "It increases the biodiversity of the species".
<u>Answer:</u> Option C
<u>Explanation:</u>
The phenomenon that support the organisms to find similar and favourable environment to acquire food, build home, satisfy with weather, feel safe and attract mates to produce more offspring in order to improve evolutionary fitness is called as an "Adaptation".
The three main forms of adaptations are behavioural, structural, and physiological adaptations that are based on the way how genetic variation get communicated. Many species have all those types of combinations. For an instance, behavioural adaptations are bird's calling and migration.
