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.
Hypothesis: If the pH is related to the growth of oysters and oysters are placed in water with varying pH levels to test growth, then (INSERT YOUR LEVELS HERE, MORE BASIC WILL HAVE THE BEST GROWTH, MORE ACIDIC WILL HAVE THE WORST GROWTH. WHAT IT SHOULD LOOK LIKE then the pH of 3 will have the least amount of growth followed by the pH of 5, 7, and 9.). This will happen because a lower pH means less carbonate which oysters require to build their shells. As the acidity rises, oyster's shells will become thinner meaning slower growth and death rates will rise.
Independent Varible: pH (I would probaly also add the pH of what like it should be the pH of water)
Dependent Variable: oyster growth
Answer:
Explanation:
Dr Mrs Brown has now antigen on her red blood cells because Blood type Of are often refer to null because it has neither antigen A or B. Therefore it is null.
But blood type Of normally have both A and B antibodies in the blood cells.
Answer:
The aerobic phases of cellular respiration in eukaryotes occur within organelles called mitochondria.
False:
Evaporation is the process of liquid becoming a gas. For example, think of boiling a pot of water, you see gas going up. That is an example of evaporation.
