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!
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.
If an onion cell contained 16 chromosomes at the start of Gi, how many chromosomes would be present in each of
the two daughter cells produced after mitosis? Explain your answer

Kettlewell's experiment is included in most biology texts as an example of evolution occuring. How do we know that the moths evolved?
(peppered moths)
Answer:
The environment the moths lived in used to be unpolluted. This made dark moths rare. As the area where light moths were found became more polluted, the light moths became less common in the polluted/dark areas. Light Moths began to evolve after not being able to survive in dark forests, they began to get darker and blend in with the polluted area to be safe from predators.
Explanation:
The evolution of the moth is an evolutionary instance of directional color change in the moth population as a result of air pollution due to the industrial revolution.
During the nineteenth century in the United Kingdom, the dark (melanic) form of the peppered moth become the dominant form of the peppered moth. Before this change, there are very fewer numbers of dark moths were present and light-colored moths were common.
This change in frequency occurred due to Industrial Revolution as it increased air pollution and trees became darker.Due to this change, light-colored moths were visible to birds and this leads to increase predation of these moths.The darker form of the moth was less visible to predators.The color change was due to adaptive evolution mainly to a single gene, with the melanic allele being dominant to the non-melanic allele. At the end of the twentieth century, the atmosphere become clear once again in the United Kingdom.The new changes would lead to a decrease in the frequency of the melanic form.Thus, the evolution of moths was due to the adaptive selection type of natural selection.

What would happen most likely happen to the population of zebra if lions went extinct
Answer:
If lions did not exist, there would be a symbiotic relationship between parasites and herd animals. This way, parasites could increase and spread throughout the herd, resulting in fewer healthy animals. Where predators like lions do not exist, smaller carnivores tend to increase.
The population of zebra would continue to increase in size, if lions went extinct.
What is a carnivore?A carnivore can be defined as an animal whose food and energy requirements are primarily (solely) derived from animal products, especially through hunting and scavenging.
This ultimately implies that, a carnivore is a living organism (animal) that typically feeds on other living organisms (animals) such as zebras, rather than plants or grasses.

Two primary agents of cellular communication are
Two primary agents of cellular communication are hormones and chemicals produced by nerve cells.
What are the principles of cellular communications?
Cellular communication is a stepwise process that affects the generation of an extrinsic signal, detection of the signal by a receptor, transduction of the signal by intracellular signalling molecules and cellular response. When the extrinsic signal is removed, cellular communication processes cease.
Thus, hormones and chemicals are two primary agents of cellular communication.

In cattle, a single gene with two alleles determines fur color. The fur can be red, white, or roan. Roan fur has both red and white hair. Which of the following is true about alleles for fur color in cattle?
The allele for roan fur color is dominant over red and white fur color.
The allele for red fur color is dominant over white and roan fur color.
The roan and white alleles are expressed independently of the other.
The red and white alleles are expressed independently of the other.
Answer:
D
Explanation:
D the red and white alleles are expressed independently of each other. You know this because roan is when both red and white are present. So therefore, because of this, the cow can be red, white, or both depending on what alleles are present.

write two sources of each of Nitrogen Phosphorus and potassium required for the growth of plant
Answer:
Do Nitrogen, Phosphorus, and Potassium Fertilizers Do for Plants? Nitrogen in Fertilizer. In simple terms, nitrogen promotes plant growth. It is associated with leafy, vegetative growth. Phosphorus in Fertilizer. Phosphorus is involved in the metabolic processes responsible for transferring Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element. Nitrogen is essential to in making sure plants are healthy as they develop and nutritious to eat after they’re harvested. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
Explanation: hope im right
Minerals like feldspar and mica are the main suppliers of potassium in soil. The earth provides phosphorus to plants. Usually in the form of synthetic fertilizer or livestock dung, farmers apply phosphorus to soil. The primary source of nitrogen in atmospheric deposition is the combustion of fossil fuels like coal and oil.
What is fertilizer?Fertilizer, a natural or synthetic substance with chemical components that enhance plant growth and productivity.
The primary sources of potassium in soil are minerals like feldspar and mica. Plants receive phosphorus from the ground.
Farmers add phosphorus to soil, typically in the form of synthetic fertilizer or livestock manure. The burning of fossil fuels like coal and oil is the main cause of nitrogen in the atmosphere.
Plants can take up nitrogen from the soil as [tex]NH^4^+[/tex] and [tex]NO_3[/tex] ions, but most of it is taken up as nitrate due to how common nitrification is in agricultural soils. As plant roots take up water, nitrate readily travels in their direction.
Thus, these are the sources of each of Nitrogen Phosphorus and potassium required for the growth of plant.
