Why is it important for science to be falsifiable and testable?

Given funds and available land sufficient to protect a given quantity of land (10,000 ha for example), how would you decide the best size, shape, and configuration of areas to protect? Explain.

1. What are the functions of the following elements found in eukaryotic cells? a) lysosome b) Golgi apparatus c) mitochondria d) endoplasmic reticulum

What are the differences in cell envelope structure between gram-negative and gram-positive bacteria? How might these differences become important if you wish to genetically engineer bacteria to excrete proteins into the extracellular fluid?

B cell Generation/Activation/Differentiation

Briefly describe the Linnaeus system or binomial system

Enumerate the classification of organisms in domains

Describe the chemical and electrical signals

In fruit flies, a grey body is dominant to a black body, and normal wings are dominant to vestigial wings. Flies are heterozygous for both grey bodies and normal wings were crossed with flies that had black bodies and vestigial wings. The following results were obtained:

The results indicate that the genes for wings and body color are on the same chromosome. The recombinant offspring are a result of crossing over.

How many map units (expressed as a percentage to the nearest whole number) apart are the two genes?

Relate the important findings of communication between organisms

Enumerate the important facts of organism's reproduction

Relate the most importance's facts of organisms grow and develop

The male hormone system is _______ and the female hormone system is _______.

a. constant;cyclic b. cyclic; constant c. cyclic; cyclic d. constant;constant

Please explain why

Rapid advances in the field of molecular and cellular biology have unwillingly unleashed the potential for creating viruses and bacteria more virulent than nature's worst. In the summer of 2002, Researchers at the State University of New York at Stony Brook described the first de novo biochemical synthesis of a virus, based on published gene sequence information and using "off the shelf" commercially available DNA material. After they pieced together genetic sequences to form a full-length poliovirus, they successfully replicated and translated this material cell-free in test tubes. The resulting nucleic acids and proteins were then able to assemble spontaneously into fully infectious viral agents. The scientists began their work from genetic blueprints that exist in the public domain, that is, in published journal articles and on internet databases. The ability to manufacture an infectious agent from scratch using preexisting, published knowledge is an unsettling development. The theoretical possibility that current knowledge could permit the creation of potential agents of biological warfare generated intense media interest around the world. As a result of studies like that at Stony Brook, an ethical debate has arisen over whether such research should be pursued, and if so, whether the details of such research should be published. Some argue that the pursuit and publication of such research unwittingly aids would-be terrorists; others argue that the dissemination of information is necessary for the effective sharing of research within the scientific community and for science to progress.

In 250-300 words, explain which side of the debate you support and why (TYPE ANSWER PLEASE).

What is the difference between a nucleoside and a nucleotide? Why do you think it is important that the sugar phosphate backbone of DNA is held together by covalent bonds, and the cross-bridges between the two strands are held together by hydrogen bonds?
