Answer:
In a pinhole camera, light passes through the pinhole to project an upside-down image onto the back of the box, and in the human eye, light passes through the lens to project an upside-down image on the back of the retina
Biomass pyramids show the amount of organic material at each trophic level; thus, they are the best type of ecological pyramid to use in order to model the flow of matter through an ecosystem. A numbers pyramid would not as accurately display this kind of information because a larger producer, such as a tree, which contains a great deal of matter, would be able to feed hundreds or thousands of small first-level consumers such as wood-eating insects.

1. The population is under selection pressure from predators
<span>2. Hey now, no population is ever at H-W equilibrium: </span>
<span>mutations happen </span>
<span>immigration and emigration can occur </span>
<span>the population is not huge, which means that genetic drift can happen </span>
<span>mating is not completely random -- a rat is more likely to mate with someone local than with someone living in Paris, France. </span>
<span>b) The small rats will be selected for (assuming there are predators in this ecosystem that are less likely to look in bushes, and further assuming that the small rats do not have reduced fertility by dint of being small) </span>
<span>This is "directional selection" </span>
<span>c) I would expect the "smallness" allele frequency to increase in this population over time, and the "normal size" allele frequency to decrease.</span>
Contracture develops when normally elastic connective tissue are replaced with nonelastic fibrous tissues.
Contracture is the prolonged state of shortening or tightened tissue. Contracture develops when the normally stretchy tissues are replaced by non stretchy fiber-like tissue. This tissue makes it hard to stretch the area and prevents normal movement. It mostly occurs in the skin, the tissues underneath, and the muscles, tendons, ligaments surrounding a joint.
The answer is “passive rGEs”. rGes ascend due to the way their
offspring receives both their genes and their environment from their parents. These
so called rGEs are given to their offspring like a package. Passive rGEs take place
only when genetic factors that are mutual to mutually a parent and a child stimulus
nurturing conducts. This can be linked with both progressive or undesirable results.
