Answer is the phylum is Pteridophyta. Pteridophytes are first land plants, examples ferns, <em>Lycopodium, Selaginella. </em>Members have liginified cells and developed conducting tissues called vascular system to conduct water and synthesized food. They reproduce through spores, seeds do not develop in pteridophytes.
The ileum has <span>plicae circulares</span>, villi and microvilli, that are folds and projections of the mucosa layer of the ileum, that increase the surface area of food absorption. The mucosa and the submucosa of the stomach have inner folds called rugae that increase the surface areas in which food is digested by enzymes.
Plants have root hairs in their tap roots that also increase the surface area for which they absorb water and nutrient from the soil. Fibrous roots have a mesh-like a network that also increases the surface area for increased absorption.
Size, location, how tall or short it is and the animals that are near it
Answer:
The correct answer is b
Explanation:
A biogeochemical cycle corresponds to an exchange of different elements such as carbon, nitrogen, water, phosphorus, nitrogen, carbon and other elements, between living beings and the environment (either decomposition or production processes).
Your question has been heard loud and clear.
A vector is basically a quantity that has both magnitude and direction.
However , scalars only have magnitude , but vectors possess both magnitude and direction.
Examples of vectors are : Velocity , displacement , acceleration.
Thank you
