California is home to the largest, tallest, and oldest trees on earth, all of which are gymnosperms.
Gymnosperms are plants that have seeds and are usually coniferous trees. Given that those largest, tallest, and oldest trees are sequoias, this seems to be the correct answer.
Nonvascular plants are quite small. Seedless vascular plants is also incorrect, because sequoias have seeds. Angiosperms are flowers.

rewona [7]

The answer is graded potential<span>. Its made of various action potentials that depolarise the neuron incrementaly, in short interspersed intervals that do not give time for the neurons to return to resting potential. Therefore, the actions potentials, of varying sizes, grade up in sum and when they cumulatively reach the threshold level, they invoke an impulse in the nerve</span>

The large surface area in the gut directly facilitates _____.

Flura [38]

Answer:

B. Absorption

Explanation:

Absorption is a process that takes place in the small intestines or ileum of the GI tract, in which simple and soluble nutrients are absorbed into the blood stream.
Absorption is enhanced by several adaptations of the gut such as large surface area of the gut which directly facilitates absorption of nutrients.
Presence of villi and microvilli in the gut increases the surface area for absorption of nutrients in the ileum.
