Answer and Explanation:
The cardiac cycle throughout mammals consists of four main different steps of activity:
- Isovolumic relaxation: During which the AV valve is locked, the Semi-Lunar valves are closed. One such stage consists of a ventricular contraction.
- Inflow Stage: And the same for atrial systole, and during that blood going back to the heart circulates via the atria to comfortable ventricles (left or right). AV valve remains located as well as the semi-lunar valve does seem to be inaccessible. The whole stage is known as the ventricular filling venue.
- Isovolumic contraction: Both the AV valve as well as the Semi-lunar valve remain sealed or disabled. AV Valve decides to close at either the final moment including its ventricular, this same blood circulation slows down the ventricle from contracting.
- Ventricular Ejection stage: This valve seems to be closed as well as the Semi-lunar valve is accessible. Ventricles or even blood need to circulates from the heart and lungs to the tissues as well as to the surrounding tissue or human body.
In the Wealth of Nations, Adam Smith makes the case for comparative advantage or the production of goods by nations or peoples which they are best at and trading for the goods with a higher opportunity cost. Therefore, he would say that a nation should diversity when it can to use its resources to produce goods and services more efficiently than other nations and also that nations should export and import as many different types of goods as possible.
Answer: Economic imperative
Explanation: The economic imperative is, in fact, changeable, and it is a set of principles that governs the company in order to achieve the best possible strategy in the market. This is therefore a principle that changes as market conditions change, in line with the needs of the market, that is, customers. Thus, the business strategy changes from the national to the global level, in parallel with changes in cultural values and time. Thus, with these changes, the economic imperative is also changing in order to make a profit, so the company is also guided by the needs of both the national and global market, together with the conditions and trends of the time and consumer culture of the time.
So Russ is guided by the company's policies, that is, his economic imperative travels the world to present his company's products as a seller globally. This means the trend of time and consumer culture and values are such that according to the products of his company he sells, he has to travel globally.
Answer:
D) I, II and III
Explanation:
i. Shelter Belts
Strong wind typically carry enough force to destroy the surface of the farm's land, which will accelerate the rate of land degradation. Usually, farmers put shelters belts at the edge of the farm to block such winds and prevent the soil degradation.
ii. No till farming
In this method of farming, Farmers avoid the use of tools that will destroy the composition of the soil (Such as shovel or rake). They plant the crops by creating as little disruption as possible to the soil to prevent soil degradation
iii. Animal graze over plowing.
The concept is similar to no-till farming. Animal plowing usually conducted by making a buffalo carried a giant rake to destroy the soil and provide spaces for Fertilizer. Animal graze will eliminate the use of the rake and prevent soil degradation.
