The limbs of crocodiles, birds, whales, horses, bats and humans all look very different they share the same five fingered bone structure.

This provides evidence for the theory of evolution .

Phenotype refers to an individual's observable traits, such as height, eye color and blood type.

A person's phenotype is determined by both their genomic makeup (genotype) and environmental factors.

The final product of carbohydrate digestion is primarily glucose along with some fructose, glucose, and galactose, while amino acids are the end products of protein digestion.

Tail wagging, bright colors, mouth gaping/display, inflation, body posture, head bobs, and 'push-ups' (some animals are capable of changing color to attract mates) are some displays that allow lizards to send signals to translate to a potential mate

As photosynthetic organisms, plants take up atmospheric CO2, chemically reducing the carbon.

This represents not only an acquisition of stored chemical energy for the plant, but also provides the carbon skeletons for the organic molecules that make up a plants' structure.

Bread mold is saprophytic, as are most types of fungi.

An organism that is saprophytic is one that feeds off of dead or decaying.

Wind direction is usually measured using a wind vane. 

AS and AS should not marry, there is every chance of having a child with SS. AS and SS

AA marries an AS. You'll end up with kids with AA and AS which is good.

Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells.

These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

Rainforest trees are quite different from trees of temperate forests. In the rainforest, trees grow to gigantic size, supported by strong, strut-like buttresses at the base of the trunk that help to stabilize them in shallow forest soils. Huge creepers twine themselves around the trunks of trees.
