Blood, the carrier of nutrients, wastes, and gases, circulates within blood vessels through the body, exchanging materials with the interstitial fluid.
Interstitial fluid, formed by filtration from blood, is the fluid surrounding body cells in the tissue spaces and is essential to proteinless plasma.
Lymph is the protein-containing fluid that enters the lymphatic capillaries (from the tissue spaces); hence, its composition is the same as that of the interstitial fluid.
The correct answer is D.
A keystone specie refers to a plant or animal which play very important roles in the way a particular ecosystem functions. Without the keystone specie the ecosystem will be totally different or even cease to exist, thus keystone species have strong influence on the ecosystems in which they exist. Most of the time a keystone specie is a dominant predator whose removal allow a prey population to increase dramatically in size and thus reduce the overall diversity in that particular ecosystem.
Answer:
I would choose the arthropod phylum, a new spider.
Explanation:
The morphology will be as a new blue spider, with 8 legs, and apparently another small helping leg, their abdomen is twice the size of its head, its spinneret is as big as its pedipalp. The males has the double size of the females. At night brights with ultraviolet light.
The main adaptation of this spider is that because of its blue color, the main house in which it lives is a blue big flower, at night the main defense is its bright color that it seems a light so can drive away its predators.
Answer: Carbohydrates like sugar and starch are readily broken down into glucose, which is the body's main energy source. Glucose can be used immediately as fuel or stored as glycogen.
During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
