how many species live in planet Earth? - ANSWER-unknown-roughly 3 to 5 million why is life so incredibly diverse, yet so strangely similar? - ANSWER-organisms can contain similar features. planes have wings, birds have wings-this feature is useful for different things (different for penguins, pelicans, bats, eagles) true or false: biodiversity on earth will likely decrease in the near future? - ANSWER- true or false: scientists believe in evolution even though they currently lack eviden...

environmental pressures correct answers the factors (abiotic or biotic) in an ecosystem which put pressure on an organism's survival and increase competition (whether inter-species or intra-species) biodiversity correct answers a combination of the species diversity, genetic diversity and habitat diversity of an ecosystem variation correct answers the differences, either physical or genetic, between individuals of a species simpson's diversity index correct answers a measure of divers...

AQA A-level Biology - Topic 4 Questions and Answers 100% Solved Define variation Differences that exist between individuals In what ways can variation be caused? It can be caused by genetic factors, such as alleles from mutations. It can also be caused by the environment, such as climate. Most variation is caused by a combination of genetic factors and environmental factors Why is it impossible to study a whole population? Because it is too large and would take too long. Instead, scient...

Test Bank For Pathophysiology 7th Edition by Jacquelyn L. Banasik 1. C.Q. was recently exposed to group A hemolytic Streptococcus and subsequently developed a pharyngeal infection. His clinic examination reveals an oral temperature of 102.3F, skin rash, dysphagia, and reddened throat mucosa with multiple pustules. He complains of sore throat, malaise, and joint stiffness. A throat culture is positive for Streptococcus, and antibiotics have been prescribed. The etiology of C.Q.’s disease is ...

Cell Theory - All organisms are made of cells, and all cells come from pre-existing cells. Conclusion: If you trace a cell's lineage back far enough, you will discover that all cells are descended from a common ancestral cell Evolution - The heritable change in a population over time or a change in gene frequency in a population over a number of generations Proximate process - what happens in short term, measured in fractions of lifetimes Ultimate process - longer timeframe (lifeti...

When explaining genetic coding to a group of students, the instructor discusses gene activation and deactivation. It was stressed that inactivation of a gene requires which of the following processes? Correct Answer-Methylation of histone amino acid When an infant is born with gene mutations in his cells, the nurse explains to the parents that accidental errors may be a result of: Select all that apply. Correct Answer-Loss of one or more base pairs Substitution of one base pair for another ...
