Why is it beneficial to use textiles made from synthetic fibers
mestny [16]
Synthetic fabrics<span> are </span>textiles made<span> from man-</span>made fibers<span> rather than natural </span>fibers. Chemically produced fabrics<span> are </span>made<span> by joining monomers into polymers, through a process called polymerization. A </span>synthetic fabric<span>, when magnified, looks like plastic spun together.</span><span>

Natural fabrics, such as cotton, silk, and wool, are made from animals or plant based fibers. While synthetic are man made and produced entirely from chemicals to create fabrics. such as polyester, rayon, acrylic, and more. The benefits of using textiles made from synthetic fibers is that it saves the animals and plants that the fibers are based off of. 

Hope this helped :)

A new mutation arises in one person on the island of Kiribati (human population size 100,000). Assuming this particular mutation
tatuchka [14]

Answer:

0.999999 ≈ 1

Explanation:

In a population ( N ) there is the presence of 2N alleles in the population also chance of fixation can be expressed as ; 1/ 2N

Therefore the probability that the mutation will be lost due to genetic drift

= 2N - 1 / 2N ---- ( 1 )

given that ; N = 100,000

back to equation 1

P ( losing mutation due to genetic drift ) = ((2*100,000) - 1 )) / ( 2* 100,000 )

= ( 200,000 - 1 ) / 200,000

= 0.999999 ≈ 1

In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of
AlexFokin [52]

Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.

Explanation:

POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.

From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.

It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.
