Answer:
macromolecules: carbohydrates, lipids, proteins, and nucleic acids.
so the answer is macromolecules
Explanation:
The virus that causes rabies travels up nerve cells to the brain and spinal cord. Endosomes cell structures will allow the virus to move through the nerve cells
The main function of endosomes is intracellular sorting. They control the movement of proteins and lipids between the plasma membrane Golgi, the trans-Golgi network (TGN), and vacuoles and lysosomes, among other subcellular compartments in the secretory and endocytic pathway.
Endocytic carrier vesicles move materials destined for lysosomal breakdown from early endosomes to late endosomes. Later, late endosomes merge with transport vesicles carrying lysosomal hydrolases from the trans-Golgi network (TGN), maturing them into lysosomes.

Botana curus is a plant that produces curus which is a substance that is used to cure different kind of cancer.
This is an endangered species that cannot be grown in the laboratory. The ability to produce curus in the laboratory is not feasible.
The human activities that could have endangered botana curus is:
Pollution: It lead to slow down the rate of growth of the plant.
Overexploitation: The over use of plant for its medicinal purpose.
Habitat: The natural habitat of the plant has been changed due to various human activities.
Answer:
A and E are the correct.
Explanation:
Examples of the structures that determine function:
a) <u>Chloroplasts </u>only found in plant cells. They work to fix the CO2 in the presence of <u>light energy</u> (sunlight) and convert the reactants into <u>sugar molecules (carbohydrates</u>) that can be used by cells for metabolic functioning.
e) <u>Sperm</u> is the male reproductive cell. Motile sperm cells have a tail-like structure that typically <u>move via flagella</u> and requires a water medium in order to swim toward the egg <u>for fertilization</u>.
Other options are not correct because <u>they don't explain their function according to their structure</u>.
