Answer:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.

What are sources of carbon?Carbon is one of the most important elements for life on Earth, and it can be found in a variety of sources. Some of the most common sources of carbon include:
Fossil fuels: coal, oil, and natural gas are all made from carbon-based materials that have been buried and transformed over millions of years.Plants: Plants take in carbon dioxide from the atmosphere during photosynthesis and use it to build their tissues.Animals: Animals obtain carbon by eating plants or other animals.The ocean: The ocean contains dissolved carbon dioxide, which can be absorbed by marine organisms and transformed into calcium carbonate, a key component of shells and other structures.Soil: Carbon is stored in soil as organic matter, such as decaying plant and animal material.The atmosphere: Carbon is present in the form of carbon dioxide, methane, and other gases in the atmosphereLearn more about carbon sources, here:

A lake has very deep water at the bottom, in the benthic zone. Why is it more difficult for plants to live in the benthic zone of this lake than in the limnetic zone
Answer:
See the answer below
Explanation:
It is quite difficult for plants to survive in the benthic zone due to the limited penetration of light in the zone when compared to the limnetic zone. The limnetic zone is a well-lit area of a lake or pond while the benthic zone represents an area around the bottom of any water body - marine or freshwater.
Light is an important factor for plants because the light is necessary for photosynthesis - a process through which plants get their foods. Hence, due to limited light in the benthic zone as opposed to the limnetic zone, plants would find it easier to survive in the latter compared to the former.

Give an example of exaptation in humans.
Answer:
As an example of an exaptation, Gould (1991) used the large size of the human brain and its function of enabling humans to produce speech. The large brain size, according to his argument, originally arose as an adaptation for some (unspecified) functions in humans' ancestral past ( Gould, 1991 ).

All Archaea and bacteria are microscopic, prokaryotic organisms. However, Archaea and bacteria differ in significant ways. Which of the following is the MOST important reason that Archaea and bacteria belong to separate biological domains?
Archaea are often resistant to antibiotics
O Archaea do not have a nucleus
O Archaea are found as single cells or colonies
O Archaea often live in more extreme conditions than bacteria
The most important reason that Archaea and bacteria belong to separate biological domains is Archaea often live in more extreme conditions than bacteria.
What are the examples of biological domains?There are three domains of life, the Archaea, the Bacteria, and the Eucarya. Organisms from Archaea and Bacteria have a prokaryotic cell structure, whereas organisms from the domain Eucary encompass cells with a nucleus.
Examples include memory, mate choice, relationships between kin, friendship and cooperation, parenting, social organization, and status.
This phylogeny overturned the eukaryote-prokaryote dichotomy by showing that the 16S rRNA tree neatly divided into three major branches, which became known as the three domains of (cellular) life: Bacteria, Archaea and Eukarya.
