Swamp coolers which use evaporational cooling are a good way to cool homes and buildings in South Carolina.
zalisa [80]

4. Evaporative cooling can be defined as the process of removal of the latent heat from a surface by the evaporation the evaporation of a liquid from there, which results in the reduction of the temperatures. This technique is used for cooling the homes in the dry and hot areas, such as South Carolina. The dry and hot surrounding there makes it easier for the water to evaporate when it passes through the evaporative coolers, making the surrounding air cooler.

Hence, the given statement is true.

5. When the outside temperature is as high as 83 degree Celsius, while the relative humidity is 66%, , it is likely that the sweating will take place, and the water will be evaporated from the skin, making a person feel cooler.

Hence, the given statement is true.

8-4 Discounting the Transverse Carrier Model. At one time, membrane biologists thought that transport proteins might act by bind
Natasha_Volkova [10]

Answer:

The two main reasons are nonpolar core of the bilayer and the active transport.

Explanation:

The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.

If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.

One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>

Identify the parts of the female and male reproductive system and their functions. ​
Lena [83]

<u><em>Female:</em></u>

*Ovaries - release of oocytes (eggs), estrogen and progesterone.

*Oviducts (fallopian tubes) - where fertilization of the oocyte occurs to form a zygote.

*Uterus - where the zygote develops

*Cervix and vagina - allow for the entry of sperm for fertilization

<u><em>Male:</em></u>

*Testes - Releases testosterone and sperm

*Vas deferens - Passageway for sperm

*Epididymis - allows the sperm to pass from the testes and vas deferens and equips them with semen so they can survive internal fertilization

*Penis - releases sperm into the external environment for fertilization to occur

I hope I helped!
