Answer:
Explanation:
A. False - A symporter system requires that one of the molecules to be transported using passive transport.
B. True - The Na+ will move down the established concentration gradient releasing energy to facilitate movement of sucrose against its concentration gradient. This is known as secondary active transport.
C. False - sucrose moves through ion channels not by diffusion to better control its movement across the membrane.
D. True - Movement of molecules against their concentration gradient thus requiring energy input is known as active transport.
E. False - One of the molecules needs to be moving against its concentration gradient.
F. False - A Uniporter system allows the binding and transport of a single molecule at a time. A symporter allows simultaneous binding and transport of Na+ and sucrose molecules.
Answer:
All of the above.
Explanation:
Reflex arc may be defined as the neural pathway that control the function of the reflex system of the body. Two main types of reflex arc are somatic reflex arc and autonomic reflex arc.
The afferent neuron carries signal from the receptors to the integrating center via the interneuron. The efferent neuron carries signal from the integrating center to the effector organ via the inter neuron.
Thus, the correct answer is option (e).
Answer: Gamete
Explanation: <u>Gametes are an organism's reproductive cells.</u> They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
