Based on ecological studies, the definitions below applies to the given terms:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

<h3>What is ecology and what are some terms in ecology?</h3>

Ecology is the study of living things and their interactions with their environment.

Some terms in ecology include:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

What is the mass of 4.5 x 10^22 molecules of hydrogen peroxide (H2O2)? Show your work in the space below.
valentinak56 [21]

Given :

Number of molecules of hydrogen peroxide, N = 4.5 × 10²².

To Find :

The mass of given molecules of hydrogen peroxide.

Solution :

We know, 1 mole of every compound contains Nₐ = 6.022 × 10²³ molecules.

So, number of moles of hydrogen peroxide is :

n = \dfrac{N}{N_a}\\\\n = \dfrac{4.5\times 10^{22}}{6.022\times 10^{23}}\\\\n = 0.0747 \ moles

Now, mass of hydrogen peroxide is given as :

m = n × M.M

m = 0.0747 × 34 grams

m = 2.54 grams

Hence, this is the required solution.

Why is it commonly believed that carbon dioxide is responsible for global warming? Select 2 options.
monitta

Answer:

Carbon dioxide levels in the Earth's atmosphere have been steadily increasing.

Carbon has a longer average lifetime in the atmosphere.

Explanation:

Today the level of carbon dioxide is higher than at any time in human history. Scientists widely agree that Earth’s average surface temperature has already increased by about 2 F (1 C) since the 1880s, and that human-caused increases in carbon dioxide and other heat-trapping gases are extremely likely to be responsible.

The lifetime in the air of CO2, the most significant man-made greenhouse gas, is probably the most difficult to determine, because there are several processes that remove carbon dioxide from the atmosphere. Between 65% and 80% of CO2 released into the air dissolves into the ocean over a period of 20–200 years.
