Answer:
Explanations below
Explanation:
A. Wind power:
In the principle of wind power energy, the wind turbine used in the process has blades that look like propeller. When the wind turns the blade around a rotor, it spins a generator and electricity is being generated.
B. Water power (also called hydroelectricity):
The hydro power process is similar to that of the wind power. At the hydropower plants in different localities, one would notice the flow of water through a pipe, which turns the blades in the turbine, to spin a generator and electricity is being produced.
C. Solar power:
In solar power generation, solar panels are used. The required solar energy is produced when sunlight strikes the solar panels and that converts the solar power into electricity that can be used.
D. Ethanol:
Ethanol is a renewable biofuel which can be made from different things such as grasses, corn cobs and stocks, rice straw, sawdust, and wood chips. During the process, yeast is used to ferment the start and sugars in the corn and sugar cane. The starch is fermented into sugar which can also be fermented into alchohol [ethanol].

Tell me one thing you know about replication.
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.
a. True
b.False
Answer:
a. True
Explanation:
AZT is an abbreviation for azidothymidine and it is the first effective drug against the human immunodeficiency virus (HIV). Thus, azidothymidine is considered to be the first anti-retroviral drug used for the prevention and treatment of the human immunodeficiency virus (HIV).
AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.
Basically, the shape and composition of the reverse transcriptase plays a significant role in the interaction. Therefore, this anti-retroviral drug known as AZT may not work effectively if the shape and composition of the reverse transcriptase changes.
Furthermore, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.
Hence, the human immunodeficiency virus (HIV) possesses a high error rate.

One nucleotide in a DNA strand is replaced with another, but the change results in
the same amino acid to be placed next in the protein. What is this type of mutation?
nonsense
point
silent
frameshift
Answer:
The type of mutation that occurs when one nucleotide in the DNA strand is replaced by another, but the change results in the same amino acid to be placed next in the protein is a silent mutation.
Explanation:
Silent mutations are molecular mutations where, despite a change in one of the DNA nucleotides, this change has no impact on the amino acid sequence that a synthesized protein will have.
An example of a silent mutation is the change in a DNA sequence TTC where a thymine replaces the cytosine, obtaining the TTT sequence:
Normal With mutation
DNA TTC TTT
mRNA AAG AAA
Amino Acid Lys Lys
There was a nucleotide change in the DNA, but the encoded amino acid was the same, which is a silent mutation that does not affect the amino acid sequence of a protein, its structure or function.

Complete a model to explain the molecular events occurring at each stage of this reaction profile. Rank the stages from the first to the last one.
The substrate molecules are entering the cells, so no product is made yet As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
There is sufficient substrate, so the reaction is proceeding at a maximum rate
Section A Section D
Answer:
The substrate molecules are entering the cells, so no product is made yet.
There is sufficient substrate, so the reaction is proceeding at a maximum rate
As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
Explanation:
First the substrate molecules enters in the cell and no product is produced because the reaction is not started yet. When the reaction starts, the substrate is in large amount while on the other hand, the amount of product is low. As the reaction proceed forward, concentration of substrate is lowering and concentration of product is increasing. When all the substrate used up, so no new product is formed.

a) T Cell Helper Line
b) Macrophage cell line without CD4
c) Unedited wild type macrophage
d) Edited macrophage
Explanation:
Human immunodeficiency virus type 1 (HIV-1) enters target cells by first binding to the primary receptor CD4 and then to a coreceptor, generally one of the chemokine receptors CCR5 and CXCR4 (4). CD4 binding induces structural changes in the envelope (Env) glycoprotein that form and expose the coreceptor binding site. There are two main interactions between Env and coreceptor (13, 14, 25, 50, 51): the base of the third variable loop (V3) engages the N terminus of the coreceptor, while the crown of the V3 loop that includes the highly conserved GPGR/Q arch motif binds to the extracellular loops of the coreceptor, with the second extracellular loop of the coreceptor being particularly important (16, 25, 35, 48, 62). Although some HIV-1 strains are able to use a variety of different G protein-coupled receptors to gain entry into CD4+ cell lines, the great majority of these viruses use CCR5 and/or CXCR4 as coreceptors to infect primary cells (3, 4, 10, 23, 47, 66). CCR3, GPR15, APJ, and FPRL-1 are among the most frequently used alternative coreceptors when overexpressed on cell lines (11, 26, 43, 47, 57). Rare cases of HIV-1 strains that are able to use FPRL-1 and GPR1, but not CCR5 or CXCR4, have been reported (57); however, their in vivo relevance remains unknown.
To characterize the biological processes underlying HIV/simian immunodeficiency virus (SIV) transmission, we recently developed an experimental strategy that permits the identification, enumeration, and molecular cloning of transmitted/founder (T/F) viruses (28, 53). This strategy, which employs single-genome amplification (SGA) and direct amplicon sequencing of HIV/SIV RNA or DNA from the plasma or infected cells, makes it possible to infer the nucleotide sequence of the viral strain(s) that initiated productive infection weeks earlier (1, 28, 29, 37, 53, 58, 67). An important prediction of this approach has been that inferred T/F viruses are fully functional and encode all proteins necessary to establish a new infection. Indeed, this prediction has been borne out in numerous studies, which have shown that T/F viral genes as well as full-length genomes are biologically active. Sets of T/F Envs have been shown to mediate efficient virus entry in single-round infection assays, and they invariably use CCR5 as a coreceptor (28, 34). Similarly, T/F infectious molecular clones (IMCs) of HIV-1, SIVmac and SIVagm all produce replication competent virus that grow to high titers in primary CD4+ T cells (22, 38, 54).
MATERIALS AND METHODS
Amplification of the HIV-1 env gene. Serial plasma samples collected from an acutely infected plasma donor, ZP6248, were purchased from ZeptoMetrix. A total of seven plasma samples were collected between 12 February and 9 March 1997, and viral loads (VLs) were determined by the COBAS Amplicor HIV-1 monitor test.
Sequence analysis. All SGA amplicons were sequenced directly by cycle sequencing and dye terminator methods using an ABI 3730xl genetic analyzer (Applied Biosystems, Foster City, CA). Individual sequences were assembled and edited using the Sequencher program 4.7 (Gene Codes, Ann Arbor, MI). The env sequences were aligned using CLUSTAL W (60), and manual adjustment for optimal alignment was done using MASE (20).

Do environmental or genetic factors affect growth of organisms most?
Answer:
Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.
I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.
