Answer:
Producers create their own energy using photosyntehsis. They absorb light and water to make glucose. Consumers have to eat, they can't make their own energy.
Explanation:
Answer:
a)BB*Bb
b)0:2:2(short: intermediate:long)
c)0
Explanation:
A naturalist visiting an island in the middle of a large lake observes a species of small bird with three distinct types of beaks. Those with short, crushing beaks (BB) consume hard shelled nuts, those with long, delicate beaks (bb) pick the seeds from pine cones, and those with intermediate beaks (Bb), consume both types of seeds though they are not as good at either. Assume that this difference in beak morphology is the result of incomplete dominance in a single locus gene. Which of the mated pairs below will have the best adapted offspring in a year in which most of the food available is in the form of hard shelled nuts? What would be the phenotypic ratio of the F1 generation resulting from a cross of Bb x bb(Short:Intermediate:Long)? How many offspring of an intermediate x short beak cross will have long beaks (assume 4)?
A) since the feed is put into consideration, then the offspring that is best adapted to feed on hard shelled but is to be considered. Cross-linking a gene BB with Bb is the best. If BB is said to be dominant then the offspring are produced will be short beak and intermediate beak in the ratio of 2:2 where both are suitable for feeding on hard shelled but.
B) The phenotypic ratio of the F1 generation (first generation or offspring) between Bb and bb is that there won't be a pure short beak(BB). Therefore 0:2:2 for short: intermediate: long.
C) for the intermediate and short beak crosslinking there won't be a long beak in the first generation when we limit the number offspring to four.
Answer:
B. hydrostatic and osmotic pressure
Explanation:
The mass movement of fluids into and out of capillary beds requires a transport mechanism far more efficient than mere diffusion. This movement often referred to as bulk flow, involves two pressure-driven mechanisms: Volumes of fluid move from an area of higher pressure in a capillary bed to an area of lower pressure in the tissues via filtration. In contrast, the movement of fluid from an area of higher pressure in the tissues into an area of lower pressure in the capillaries is reabsorption. Two types of pressure interact to drive each of these movements: HYDROSTATIC PRESSURE AND OSMOTIC PRESSURE.
The primary force driving fluid transport between the capillaries and tissues is HYDROSTATIC PRESSURE, which can be defined as the pressure of any fluid enclosed in a space. Blood hydrostatic pressure is the force exerted by the blood confined within blood vessels or heart chambers. Even more specifically, the pressure exerted by blood against the wall of a capillary is called capillary hydrostatic pressure (CHP) and is the same as capillary blood pressure. CHP is the force that drives fluid out of capillaries and into the tissues.
The net pressure that drives reabsorption—the movement of fluid from the interstitial fluid back into the capillaries—is called OSMOTIC PRESSURE (sometimes referred to as oncotic pressure). Whereas hydrostatic pressure forces fluid out of the capillary, osmotic pressure draws fluid back in. Osmotic pressure is determined by osmotic concentration gradients, that is, the difference in the solute-to-water concentrations in the blood and tissue fluid. A region higher in solute concentration (and lower in water concentration) draws water across a semipermeable membrane from a region higher in water concentration (and lower in solute concentration).

Hon, I don't think this is a question. seems more like a piece of info
