Answer:
- Numerous amino acids <u>allow for proteins to perform many diverse functions in organisms</u>.
- The branching structure of some carbohydrates <u>maximize the amount of glucose available for quick energy</u>.
Explanation:
Amino acids are the <u>building blocks</u> of proteins. In humans, <u>all forms of proteins</u> are made up of <u>20 different types of amino acids</u>. The <u>sequence of amino acids</u> is the key to the production of <u>specific proteins</u>. If the sequence is changed, the target protein will be changed. So, only 20 types of amino acids can produce millions of proteins through different combinations. For example, for a protein with 4 amino acids sequence, 160,000 types of polypeptide chains can be formed (20 X 20 X 20 X 20). Since we know that proteins are key players in cell functioning, their multiple combinations lead to diverse functions in the organisms.
Carbohydrates are an <u>excellent source of energy</u>. Although branching decreases the water solubility of carbohydrates, it <u>compacts the energy-yielding monomers</u> in a <u>small space</u> so that they can be <u>stored</u> and, during starvation, they can produce an <u>extensive amount of energy</u> for long term survival. Carbohydrates in <u>animal and plant</u> bodies are stored as branched structures of <u>glycogen and starch</u>, respectively.
Answer:
A) Natural selection caused the pigweed to mutate, creating a new triazine-resistant species.
Explanation:
Due to constant use of triazine, the weed will build resistance to it over time unlocking the herbicides codes and making it ineffective.
Natural selection will play out allowing this weeds to bring about a sudden change in their genome that will become resistance, this resistance breed is what will then be produced over time because mutation is heritable and the herbicide then becomes ineffective and the weed continues to multiply and increase in volume.
Answer:
The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.
Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.
Mitosis I think is the answer
