If a flood occurs in the natural rubber environment, it will ruin the rubber production process. The flood would damage a huge percentage of rubber trees if there was a large quantity of restriction. This natural rubber is required for the production of synthetic polymers. Without the rubber, there would be a restricted supply and a significant decline in synthetic polymers due to ecological damage caused by the flood.

What is TRUE about the North and South Poles? Select all that apply.
Romashka [77]

The poles never get any direct sunlight.

They both get the same amount of sunlight.

  • Because they receive no direct sunshine, the Arctic (North Pole) and Antarctic (South Pole) are both chilly.
  • Even at the height of summer, the Sun is low on the horizon. The Sun doesn't rise at all for several months during the winter since it is so deep below the horizon hence poles don't have equal amounts of sunlight and darkness.
  • The poles receive less energy and heat from the sun because of the tilt of the earth and its orbit around the sun. There are just two polar seasons as a result: summer and winter.
  • The tilt of the Earth's axis causes the Poles to experience around six months of day and six months of night.
  • Due to this tilt, each Pole spends roughly six months angled both toward and away from the Sun. The North Pole experiences six months of nonstop daylight when it is inclined toward the Sun.
  • In the winter, the Sun sets for extended periods of time since it is so deep below the horizon. Therefore, the days are chilly and dark, much like the nights. The South Pole and North Pole receive the same amount of sunshine despite being "polar opposites."

PROJECT: HOMEOSTASIS
Semenov [28]
Maintaining Homeostasis. The process in which organ systems work to maintain a stable internal environment is called homeostasis. ... Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). ...
 Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
There are lots of different hormones in the human body that serve lots of different functions, but some are used to maintain homeostasis of various physiological parameters, like blood glucose levels. Blood glucose levels are regulated by two opposing hormones: insulin and glucagon.

A population of mice in a meadow is growing in a pattern of logistic growth. Arrange these events in the order in which they occ
Ray Of Light [21]

Answer:

2, 3, 1

Explanation:

For logistic population growth, the initial growth is slow while the population is trying to get acclimatized to the environment but the growth increases exponentially once it is done acclimatizing. The exponential growth continues until the carrying capacity is reached and then starts to fluctuate around the carrying capacity.<u> The carrying capacity signifies the maximum size of the population that the environment can support based on the resources that it has.</u> Hence, the logistic population growth curve forms a S shape.

In summary, the correct order of events is:

  • <em>The population increase begins to slow</em>
  • <em>The population increases exponentially</em>
  • <em> The population fluctuates near carrying capacity</em>

Therefore, the order is 2, 3, 1.
