Answer:
d. Simple Columnar Epithelia
Explanation:
The simple columnar epithelium is an epithelial tissue that has a single layer of nonciliated cells. The cells look like columns and have oval nuclei near their base. This type of epithelial tissue has microvilli at the apical surface of their columnar epithelial cells. These microvilli are the fingerlike cytoplasmic projections that serve to increase the surface area for absorption.
Simple columnar epithelium makes the linings of the gastrointestinal tract, specifically from the stomach to anus where they live the cavities of these organs.
Answer:
One involves the movement of the organism, and the other involves a change in the environment.
Explanation:
Most phylogenetically related groups have distribution patterns resulting from dispersion or vicariance. In the first of these processes, the most recent common ancestor of a given group of organisms originally occurred in only one of today's occupied areas, then dispersed to other areas - overcoming pre-existing barriers - in which descendants survived. In the occupied areas, differentiation processes may occur resulting in the formation of new species. In vicariance events, the ancestral population occupied, to some extent, the sum of the areas currently inhabited by their descendants, and was divided into smaller populations by the emergence of barriers that caused isolation between subpopulations. The appearance of the barrier causes the disjunction (separation) observed and corresponds to an event that affects all or most of the biota.
From this we can conclude that the main difference between dispersion and vicariance is that one involves the movement of the organism and the other involves a change in the environment.
Solar because the sun gives radiant energy to plants to make food which makes oxygen in the process. animals eat the plants to get energy and the food chain goes on. With out the plants turning the sun into food then we wouldn't be around.
