D. Polarity and size.
<span>The size, polarity, and charge of a substance will determine whether or not the substance can cross the cell membrane by diffusion. The cholesterol was an example of a lipid, and is highly soluble in the nonpolar environment of the lipid bilayer. You saw, in the animation above, the cholesterol freely passing into the hydrophobic environment of the membrane. Cholesterol distributes freely in the membrane and then some fraction will dissolve in the aqueous environment of the cytoplasm. Water, on the other hand, while polar, is small enough to cross the membrane at a slow rate. Note that specialized transport proteins in certain cell membranes can provide a channel for the water, greatly increasing its rate of crossing the membrane. The lipid bilayer is much less permeable to the ion, because of its charge and larger size. As a general rule, charged molecules are much less permeable to the lipid bilayer.</span>
Answer:
Telescope also known as "spyglass"
Explanation:
In 1609, using this early version of the telescope, Galileo became the first person to record observations of the sky made with the help of a telescope. He soon made his first astronomical discovery.
Global warming is a phenomenon of rising the average temperature of the earth over the past 100 years.
The following would provide the best evidence to support the claim :
(A) Habitat loss would occur, leading to a decline in species diversity.
<h3>Global warming has a long term impact on the ecosystem</h3><h3 />
- The earth warming gases are carbon dioxide, methane, nitrous oxide, etc.
- As the earth will warm up, we will experience more extreme weather, heatwaves, and droughts.
- Due to heat, the glaciers are melting to a high extent.
- Due to the melting of the glaciers, the sea level is rising.
- Some animals are already experiencing extinction due to global warming.
- Due to the loss of habitat, there is a loss of diversity.
Thus, the correct option is: (A) Habitat loss would occur, leading to a decline in species diversity.
