Answer:

B

Explanation: The specific heat of any particular substance is usually defined as the amount of heat energy that is required to raise a unit mass of the material by 1°C. The water has this high heat capacity as a result of which the water bodies such as oceans, seas, and lakes tend to become hot and cold at a much slower rate.

22. Different species within a phylum all have the same basic _____.<br> (1 point)
7nadin3 [17]

Answer:

Different species within a phylum all have the same basic characters, anatomical and functional integrity, common ancestry.

Explanation:

The animals having same phylum but different species have similar basic structural pattern. That means the anatomical features are constructed on the same ground plan. This individuals have similar functional integration. All animals of a phylum work as a functional machines with similar functional integration.

Another important feature is they have common ancestry. Evolutionary study have confirmed all members of  a similar phylum have been derived directly or indirectly from a common primitive ancestry.

Which of the following is not an environmental impact of resource extraction? a. loss of soil b. increased resource supply c. wa
jeka57 [31]

The correct answer is - increased resource supply.

The resource extraction is a process though which the supply of resources on the market is achieved. In the past century, the extraction has been increasing constantly, thus the supply of resources on the market increased significantly because the demand for the same increased significantly.

On the other hand, the extraction of resources, very often, has very bad impact on the environment. The soils are destroyed, which is especially concerning considering the fact that fertile soils are desperately needed. The vegetation is cleared or polluted to a degree where it dies out, and the water also gets contaminated. Lot of this issues are extremely serious, and urgent measures have to be taken in order for such damage to be stopped.

A spheroidal bacterium with a diameter of 1 mm contains 2 molecules of a particular protein. What is the molar concentration?
creativ13 [48]

Answer : The molar concentration is, 6.35\times 10^{-18}mol/L

Explanation :

First we have to calculate the moles of protein.

\text{Moles of protein}=\frac{\text{Number of molecules of protein}}{\text{Avogadro's number}}

Number of molecules of protein = 2 molecules

Avogadro's number =  6.022\times 10^{23}molecules/mol

\text{Moles of protein}=\frac{2\text{ molecules}}{6.022\times 10^{23}molecules/mol}=3.32\times 10^{-24}mol

Now we have to calculate the radius.

Radius = \frac{Diameter}{2}=\frac{1mm}{2}=0.5mm=5.0\times 10^{-4}m

Conversion used : (1 mm = 0.001 m)

Now we have to calculate the volume.

V=\frac{4}{3}\pi r^3

V=\frac{4}{3}\times 3.14\times (5.0\times 10^{-4}m)^3

V=5.23\times 10^{-10}m^3=5.23\times 10^{-7}L

Conversion used : (1 m³ = 1000 L)

Now we have to calculate the molar concentration.

Concentration=\frac{\text{Moles of protein}}{\text{Volume}}

Concentration=\frac{3.32\times 10^{-24}mol}{5.23\times 10^{-7}L}

Concentration=6.35\times 10^{-18}mol/L

Thus, the molar concentration is, 6.35\times 10^{-18}mol/L

Which of the following could be done to help reduce global warming trends?
timama [110]

Answer: A. Plant more trees

Explanation: Planting more trees can reduce more pollution that is in the air.

B is wrong because by bottling up more water, it requires more plastic that may be littered on the ground. Raising more livestock is helps the environment through their feces, but it doesn't help global warming trends. Building more schools does not even reduce global warming trends at all. It may do more damage if machines that produces pollution are used during the process of building.

Hope this helps!!!
