Importance of plants from an economic, nutritional, environmental and medicinal point of view


Please be correct answer, and if you do not know not with this!​

Answers

Answer:

Plants are extremely important in the lives of people throughout the world. People depend upon plants to satisfy such basic human needs as food, clothing, shelter, and health care. These needs are growing rapidly because of a growing world population, increasing incomes, and urbanization .

Plants provide food directly, of course, and also feed livestock that is then consumed itself. In addition, plants provide the raw materials for many types of pharmaceuticals, as well as tobacco, coffee, alcohol, and other drugs. The fiber industry depends heavily on the products of cotton, and the lumber products industry relies on wood from a wide variety of trees (wood fuel is used primarily in rural areas). Approximately 2.5 billion people in the world still rely on subsistence farming to satisfy their basic needs, while the rest are tied into increasingly complex production and distribution systems to provide food, fiber, fuel, and other plant-derived commodities .

Medicinal plants have been used in healthcare since time immemorial. Studies have been carried out globally to verify their efficacy and some of the findings have led to the production of plant-based medicines. The global market value of medicinal plant products exceeds $100 billion per annum. This paper discusses the role, contributions and usefulness of medicinal plants in tackling the diseases of public health importance, with particular emphasis on the current strategic approaches to disease prevention. A comparison is drawn between the ‘whole population’ and ‘high-risk’ strategies. The usefulness of the common-factor approach as a method of engaging other health promoters in propagating the ideals of medicinal plants is highlighted.

_______________________________________________

*rate this answer and say thanks please!

I put this same answer on a different question.

Hi there! So among the options, there are:

Organisms will lose their habitat

Groundwater in the area will be reduced

More wood will be available for building homes

Runoff will be reduced once the streets are paved

Think about it. This is asking how the water cycle will be affected.

It wouldn't have anything to do with organisms, this is about water. It wouldn't be involving wood, since we're talking about water.

A and C are no longer options.

The answer is B, Groundwater in the area will be reduced. It took me a bit on this one, too, since it's a bit tricky. I also got it right on my exam and I do FLVS, this is in Earth Space Science.

Describe how you would use Random Sampling to determine the population of dandelions in your yard.

Answers

Answer:

randomly select different areas to count the dandelions, average the numbers and then multiply by the number of plots your grid contains. 6. In a forest that measures 5 miles by 5 miles, a sample was taken to count the number of silver maple trees in the forest.

Random sampling is used in sampling biological products. It is made up of subsets from the larger population in which the subset of individuals is selected randomly with equal probability.

It is used to collect the data for your research work.

For sampling the dandelions randomly we will first choose a distinct random area for computing the dandelion.

Estimate the average of the numbers determined before.

Now multiply the average with the design your framework contains or with the total number of squares in the yard.

Therefore this is how you calculate the random sample size.

HELP!! I WILL MARK BRANLIEDT!! HERES A PIC ITS ABOUT NATURAL AND SELECTIVE BREEDING:)

Answers

Answer:

Natural Selection

- The process happens due to environmental activity

- It takes a relatively long period of time.

- Excessive warmer temperatures in a region have caused rabbits with longer fur to slowly disappear.

Selective Breeding

- Organisms do not choose to thrive but are selected because they are best adapted to the environment.

- A Labradoodle is created by scientists to be hypoallergenic but still look like a Labrador.

- It takes place over a relatively short period of time.

- Humans have a decision in the outcome of the offspring.

- Apples have gotten much larger over the last 30 years due to customer demand

Explanation:

From the above, I have been able to place them in their respective categories.

Natural selection simply has to do with nature. It is a process in nature that leads to the better adaptation of organisms to survive and reproduce in their environment. This type has to do with the natural environment. As nature plays out, it can take longer time and the environment can affect survival rate. Natural selection can lead to speciation.

Selective breeding can also be referred to as artificial selection. This process has to do with the input of man in developing new organisms that possess desirable characteristics and that can adapt to a specific environment. In other words, humans control and decide the outcome of the species that are reproduced. Such breeding process take relatively short time.

Is the mass–kinetic energy relationship directly proportional (as one variable increases, the other increases) or inversely proportional (as one variable increases, the other decreases)?

Answers

Answer:

The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity.

Explanation:

The mass-kinetic energy relationship is ; Directly proportional

The Kinetic energy of an object is directly proportional because an increase in the kinetic energy of a moving object leads to an increase in the mass of the object and also to the increase in the velocity of the object squared.

i.e. K.E ( kinetic energy ) = [tex]\frac{1}{2} mv^2[/tex]

Hence we can conclude  that the mass-kinetic energy relationship is directly proportional.

What is the difference between primary waves and secondary waves

Answers

Answer:

Primary and secondary waves both are body waves of seismic waves. Primary waves or pressure waves are compression waves and secondary waves are shear waves. These waves are represented by P and S waves respectively.

Differences:

P waves are smaller in size but travel faster, however, cause less damage whereas S waves are greater in size cause more damage, and travel slower.

P waves move in a push-pull pattern and travel through different mediums like solids, liquids, and gases, whereas S waves move in an up-and-down pattern and travel only through one medium that is a solid medium.
