Darwin's Observation #1 - ANSWERMembers of a population often vary in their inherited traits. For example, Asian ladybird beetles vary in color and spot pattern. Darwin's Observation #2 - ANSWERAll species can produce more offspring than the environment can support, and many of these offspring fail to survive and reproduce. For example, the puffball fungus can produce many spores that give rise to many offspring. If all of the spores and their offspring survived, they would cover the surrou...

What are the five Hardy-‐Weinberg conditions ? - ANSWER What is the difference between the founder effect and the bottleneck effect? - ANSWERThe bottleneck effect is a something that happens that reduces a population such as a disaster. If there is a drought then only some population will be able to survive. A founder effect is an event of a small population finding a new population to settle down in. The main difference in the two is that bottleneck effect is because something drastic has ...

Evolution - ANSWER"descent with modification"; the view that all organisms are related through descent from another ancestor that lived in the remote past Fossils - ANSWERremains or traces of organisms from the past, usually found in sedimentary rock (one of three main rock groups) Strata - ANSWERa layer or a series of layers of rock in the ground Ancestral species - ANSWERspecies descended from ancestors found in lower strata layers Derived species - ANSWERspecies that branches of...

Endothermic Fish: rete mirable - ANSWERBluefin tuna, swordfish; heart pumps blood to gills; cold blood flows from gills to body in superficial arteries; arterial blood flowing into muscles warmed by venous blood flowing out of muscles Torpor - ANSWERState of reduced metabolic activity in which the heart rate and respiratory system slow down Hibernation - ANSWERResponse to cold (triggered by photoperiod) Aestivation - ANSWERResponse to heat or drought Nitrogenous Wastes - ANSWERammoni...

An unlearned behavior directly linked to a stimulus that is carried to completion once initiated and is essentially unchangeable is _____. 1. one that requires parental teaching 2. operant conditioning 3. a conditioned response 4. not species specific 5. a fixed action pattern - ANSWERa fixed action pattern =Fixed action patterns are genetically determined behaviors that are stereotypic and species specific. They are not modified through learning, and they occur independent of prior ex...

(type of carbohydrate) it is harder to break these bonds. found in plant cell walls provide structure Chitin - ANSWERmakes up external skeleton of lobsters and instects Types of Lipids - ANSWERfatty acids, fat or oil molecules, phosholipids, steroids, terpenes lipids - ANSWERfatty substances contain alot of energy not soluble in water fatty acids - ANSWERcha...

Methylation and acetylation, which involve chemical tags covering DNA and histones, respectively, each contribute to the... - ANSWEREpigenome What is the difference between the DNA code and epigenome? The DNA code is _____. - ANSWERFixed for life, while the epigenome is flexible. Consider the case of identical twins Joe and Sam, who are infants. If their DNA code is sequenced, what would one most likely find? Their DNA sequences _____. - ANSWERAre nearly carbon copies Consider the case ...

Hydrogen Bonds - ANSWERTwo molecules are bonded together due to the attraction of their opposite, yet partial charges. Polar Covalent - ANSWERTwo atoms are bonded together when valence electrons are shared between the two. The electrons spend more time circulating around the nucleus of the first atom than the second. Nonpolar Covalent - ANSWERTwo atoms are bonded together when valence electrons are shared between the two. The electrons spend an equal amount of time around the nucleus of ea...
