Question

1) ____is the marked differences between the sexes in secondary sexual characteristics2)____ is a process by which one species evolves into several distinct species, as the original population adapts to new or different environments. This is usually accompanied by high degrees of isolation, habitat differentiation, open niches, and a reduction in competition.3) A phylogenic tree with a line suggesting a common basal ancestor is a __________________ tree.3a) A phylogenic tree with a branch that contains two organisms, the two organisms are said to be ___________________ taxaIntronSisterParentalUnrelatedRooted4) What is the name of the theory that suggests that eukaryotic organims evolved from engulfing prokaryotic organisms and then creating an obligate relationship with them?EndosymbiontPinocytosisEvolutionPhagocytosis______5) Sexual reproduction due to recombination is the most reliable form of genetic variation on this planet.

Answer 1

1. Sexual dimorphism

2. Adaptive radiation

3. Rooted Tree

3a. Sister taxa

4. Endosymbiont

5. True

6. A supervolcano / Siberia

7. 2mm

Step-by-step explanation:

1. Sexual dimorphism is the distinct difference in size or appearance between the sexes of an animal in addition to the sexual organs themselves.

2. Adaptive radiation is the diversification of a group of organisms into forms filling different ecological niches. One species evolves into several distinct species, as the original population adapts to new or different environments. It is accompanied by high degree of isolation, a reduction in competition among species, open niche, habitat differentiation.

3. A rooted tree is a tree with countable number of nodes. In which a special node is singled out. This node is commonly referred to as the root node or eve of the tree.

3a. A sister taxa is a phylogenetic term that represents the closest relatives of a given unit in an evolutionary tree. It is any taxa derived from a common ancestral node. They branch from a common node and are closely related.

4. An endosymbiont or endobiont is any organism that lives within the body or cells of another organism most often, though not always, in a mutualistic relationship. The endosymbiotic theory deals with the origins of mitochondria and chloroplasts, two eukaryotic organelles that have bacteria characteristics. Mitochondria and chloroplasts are believed to have developed from symbiotic bacteria.

5. It is true that sexual reproduction due to recombination is the most reliable form of genetic variation on this planet. Genetic recombination is the exchange of genetic material between two different chromosomes, two different regions in the same chromosome or organisms.is a required part or process in meiosis which is a special type of cell division that leads to production of offspring with combinations of traits that differ from those found in either parent

6. The leading hypothesis is that the end-Permian extinction was caused by massive volcanic (supervolcano) eruptions that spewed more than 4 million cubic kilometers of lava over what is now known as the Siberian Traps, in Siberia, Russia.

7. If the 4x objective field has a field view of 5mm then the field view of the 10x objective would be 2mm. Field of view is how much of your specimen or object you will be able to see through the microscope.
