Answer: create proteins by bonding together amino acids.
Explanation:
Translation can be defined as the process in which the messenger RNA is decoded in the ribosome that is outside the nucleus. This is done to produce the specific chain of amino acid to produce polypeptide chain. The polypeptide chain get folded to produce protein this protein is responsible for performing functions in the cell. The genetic code determines the relation in between the amino acid sequence and base pairs in the gene.

Bart believes that mice exposed to microwaves will become extra strong (maybe he's
been reading too much Radioactive Man). He decides to perform this experiment by
placing 10 mice next to a microwave for 10 seconds. He compared these 10 mice to
another 10 mice that had not been exposed. His test consisted of a heavy block of wood
that blocked the mouse food. He found that 8 out of 10 microwaved mice were able to
push the block away. 7 out of 10 of the non-microwaved mice were able to do the same.
What was one of the constants in this experiment?
Answer:
the mice were able to move the block

For something to be considered dead, it used to do what? Plz help
Answer:
C. Carry out all 5 of the life processes but no longer can
Explanation:
All living things are characterized by their ability to grow, reproduce, use energy by respiration, respond to stimuli, and easily adapt to their environments. When a living thing loses the ability to perform all of these basic functions, then it can be said to be non-living, or dead.
In addition, locomotion, excretion, metabolism, and nutrition were all exhibited when dead things were once alive.
Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M

The function of glomerulus and Bowman's capsule of the nephron is to?
(A) reabsorb water into the blood
(B) eliminate ammonia from the body
(C) reabsorb salts and amino acids.
(D) filter the blood and capture the filtrate
Answer:
The function of glomerulus and Bowman's capsule of the nephron is to filter the blood and capture the filtrate (option D).
Explanation:
The set of glomerulus and Bowman's capsule is known as the renal corpuscle, and it is the structure responsible for the filtration of blood and its uptake as urine, which passes to the renal tubular system.
The renal glomerulus is the functional unit of the kidney, and is the structure responsible for filtering the blood that arrives through the renal capillary, to eliminate the waste products present in the blood.
Bowman's capsule surrounds the glomerulus and constitutes the second component of the filtration of blood plasma, in contact with the renal tubular system.
The other options are not correct because:
A. Reabsorb water into the blood occurs in the renal tubules.
B. eliminate ammonia from the body. Ammonia is one of the waste substances, converted to urea, that is eliminated by the kidney.
C. reabsorb salts and amino acids, occurs in the renal tubules.

in an appropriate design experiment, a scientist is able to test the effect of?
Answer:
This question is incomplete as it lacks options, the options are:
A) a single variable
B) multiple variables
C) the hypothesis
D) scientific observations
The answer is A
Explanation:
An experiment is conducted to solve a particular problem or find answers to a given scientific question. In an experiment, which usually consists of variables, only A SINGLE VARIABLE is tested at once.
This means that the effect of a variable called INDEPENDENT VARIABLE is tested at a time. The independent variable is the variable that is changed or manipulated in an experiment. This means that only a SINGLE VARIABLE can be changed at at time in an an appropriate design experiment.

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).

Listen How are channel and carrier proteins similar? Select all that apply.
A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.
B. Channel and carrier proteins are both types of facilitated transport.
C. Channel and carrier proteins can only move substances in one direction either into the cell or out of the cell.
D. Channel and carrier proteins always move substances from the side of the membrane with the highest concentration to the side with the lowest concentration.
Answer:
a
Explanation:
A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.
Channel and carrier proteins are both types of facilitated transport.
Facilitated diffusion is one of the ways of transporting molecules and is characterized by the use of proteins that are inserted in the plasma membrane, such as ion channels and carriers or permeases.
Ions, amino acids and monosaccharides, among many other molecules, cannot cross the plasma membrane, because they are polar or are very large in size.
So, for the cell to obtain or eliminate these substances, the presence of transporter proteins is necessary.
This diffusion is a type of passive transport, because it takes advantage of the concentration gradient of the molecules and does not waste energy.
Ion channels are integral tunnel-shaped proteins, selective for one, two, or three ions. When a channel opens, ions flow under two principles: the concentration gradient and the electrochemical gradient.Consequently, when an ion channel opens, the potential difference between the two compartments is altered.
Transmembrane proteins mediate the transport of molecules such as bicarbonate or large, polar, uncharged molecules such as glucose.The transport through these proteins occurs in favor of the concentration gradient, and by a reversible conformational change of the proteins that allows the translocation of the molecule to the other side of the membrane.
This type of transport is always without energy expenditure and in favor of the electrochemical gradient, it occurs in the following way:
Uniport, a single molecule translocates in only one direction.Simporte, two molecules that translocate in the same direction.Therefore, we can conclude that channel and carrier proteins are both types of facilitated transport.

Explain the relationship between the number of whales, the number of plankton (Biomass), and the amount of CO2 (Carbon Dioxide) in the atmosphere.
Answer:
Plankton are producers therefore they use the CO2 in the atmosphere and convert it to oxygen. Whales eat the plankton while sometimes using the oxygen that the plankton produces. In this situation, the whale is a primary consumer, or a heterotroph, as the plankton is the producer, or autotroph. Hope this helped :D
