Answer:
Because the have similar limbs.
Because they have similar functions.
Explanation:
(because they have similar limbs)
Homology (evolution) describes a structure that has similar function like limbs on dogs and bears (used for walking) and also have a similar arrangement of bones. The fins on a doplhin might be different from the wings on a bat but they reflect a common origin due to their bone composition e.g carpals and radius bones.
(because they have similar functions)
Analogy (evolution) describes a structure with for example, bird and butterfly wings that have no common ancestor but have the same purpose, in this case flying. They developed independtly as adaptions. This supports natural selection which is a driving force for evolution.
Water at 4 degrees centigrade has the highest density of all other water temperatures. This is why ice (whose temperature is below 0 degrees) floats on very cold water. This phenomenon is significant in the Artic and Antarctic where ice shelves float on cold ocean waters in the poles. Animals that live in these regions (such as seals and polar bears) use these ice shelves as hunting platforms.
Heat transfer means heat energy is transferred from on object or a body to another. This causes change in many factors, and temperature is one of such factors. If the temperature increases, it means heating is taking place and if temperature decreases it means cooling is taking place.
If Tfinal is more than Tinitial, it means the object has gained some amount of heat energy. Therefore, heating is taking place.
If Tfinal is less that Tinitial, it means the object has lost some heat energy and cooling is taking place.
As we can see from the graph, the average temperatures in Maine have started to sharply decline after the year 2000. If this trend continues, we should expect to see the summer flounder that residents in Maine to begin migrating to areas with warmer water, like the ones in Virginia or Massachusetts
Answer:
See the answer below.
Explanation:
<em>Let the allele for eye color be represented by A. Blue is dominant over brown eye color, hence, blue allele would be A while brown eye allele would be a.</em>
Two parents have the genotype blue/brown which is equivalent to Aa.
Aa x Aa
AA 2Aa aa
blue eyes blue eyes brown eyes
a. Different possible outcomes: AA blue eyes, Aa blue eyes, and aa brown eyes.
b. Probability of a child from the cross having brown/brown (aa) genotype = 1/4 or 25%
c. Probability that the child would have blue eye color = 3/4 or 75%
