The correct answer of the given question above would be option C. One of the human activities that would contribute in the increasing carbon dioxide levels and toxins in the atmosphere would be the burning of oil and coal. Burning of oil and coal would produce more carbon dioxide, which contributes to the formation of the greenhouse effect.

The carrying capacity of the environment for a species is determined by Question 5 options: the reproductive rate of the organis
muminat

Complete Question:

The carrying capacity of the environment for a species is determined by:

options:

(a) the reproductive rate of the organism.

(b) the number of organisms of that species.

(c) the state and national wildlife laws pertaining to that species.

(d) the age distribution of that species.

(e) the limited availability of renewable resources in the environment and the environmental resistance to the biotic potential of the organism.

Answer: (e) the limited availability of renewable resources in the environment and the environmental resistance to the biotic potential of the organism.

Explanation: The carrying capacity refers to the highest number of the species that the environment can cater for, in terms of food, space and other necessities that supports life.

Thus, the available of renewable resources (i.e resources that can be reused after consumption e.g water) in the environment, plays as a determinant of the highest number of individuals an environment can support (carrying capacity).

Furthermore, environmental resistance to the biotic potential of the organism, is also a determinant of the carrying capacity of organisms inhabiting that particular environment.

Calculate the volume of 1 M NaOH needed to prepare 12.0 mL of a 0.10-M solution. Prepare this solution. (Refer to the Dilutions
Lapatulllka [165]

Answer:

1.2 mL

Explanation:

<em>This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Recall that: number of moles = mass/molar mass or molarity x volume.

Hence, for the dilution principle:

              initial molarity x initial volume = final molarity x final volume.

In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.

Initial volume = final molarity x final volume/initial molarity

                       = 0.1 x 12/1 = 1.2 mL

It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.

Explain how scientific theories differ from scientific laws.
Sunny_sXe [5.5K]
<h2><em>In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research</em></h2>
