Why is it important that the phospholipid has both hydrophilic and hydrophobic
regions?
Answer:
The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic and hydrophobic regions.
Explanation:
Biological membranes remain fluid because of the unsaturated hydrophobic tails, which prevent phospholipid molecules from packing together and forming a solid.

Answer:
glycine and proline
Explanation:
First, a three-dimensional stranded structure is assembled, with the amino acids glycine and proline as its principal components. This is not yet collagen but its precursor, procollagen. Procollagen is then modified by the addition of hydroxyl groups to the amino acids proline and lysine.

Which of the following might make this ecosystem more sustainable?
A. if it supported more plant species, but fewer animal species
Answer:
Something that may make this sustainable is to remove food from there, or to add more animal species, particulary slightly invasive species that can eat the plants, and fast.
Oops didn't understand at first, yes this will make it more sustainable
Explanation:
To solve this we must be knowing each and every concept related to ecosystem. Therefore, an environment with a large variety of plant and animal species is the correct option.
What is ecosystem?An ecosystem is generated through the interaction of all life forms with each other as well as with the chemical and physical features of their surroundings, all of which are linked by the energy flow. It includes all of the living organisms in a given region in addition to their non - living things surroundings such as air, water, and sunshine.
Humans depend on ecosystems to meet their fundamental requirements. Ecosystems sustain us by providing safe drinking water as well as nutritious food. They supply raw materials for our clothes, housing, transportation, and energy needs. An environment with a large variety of plant and animal species is more sustainable ecosystem.
Therefore, an environment with a large variety of plant and animal species is the correct option.

Scientists have hypotheses about dark matter but need more data to test ideas.New data could cause scientist to change their hypotheses about dark matter.Scientists do not really understand what dark matter is but they have ideas about the things it is not.
For instance, scientists know that dark matter is not bright like our planet and the stars. This can be deduced from its name, "dark matter."
Scientists also believe that dark matter is not composed of antimatter. If it were, they would be able to detect this through the emission of gamma rays.
Scientists have other speculations but if new data comes with convincing proofs, they may have to change their present hypotheses.
