What is the mean of the data set [3,2,2,12,6,5,14,4]?
A.2
B.4
C.6
D.7
Answer:
6
Explanation:
To find the mean of a data set, add all the values in the set together, and then divide the result by the number of values in the set.
3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48
There are 8 values in the data set.
48/8 = 6
So the mean of the data set is 6.

Do Now: b) Complete the following mRNA Strand: GCATACAGT (Be sure to look if it is asking for DNA or mRNA. DNA is GCAT and mRNA is GCAU. All answers must be in capitals when writing out bases, or the will be considered wrong.)
Answer:
CGUAUGUCA
Explanation:
Firstly, the strand in the question is a DNA strand because it contains the Thymine base, which is only found in a DNA molecule. The process of changing a DNA molecule into RNA molecule (specifically a messenger RNA) is called transcription. Transcription is done using the complementary base pairing rule, which states that Adenine (A) will always pair with Thymine (T), and Guanine (G) will always pair with Cytosine (C).
In the case of transcription, the Thymine bases will change to Uracil (U), since Uracil is only found in the RNA molecule. That is, A-U and G-C. Hence, a DNA strand that reads: GCATACAGT will produce a mRNA strand CGUAUGUCA.

Which part of the chemical equation is incorrect?
Answer: Thus the coefficient of oxygen is incorrect.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The given chemical equation for combustion of butane is
[tex]2C_4H_{10}+10O_2\rightarrow 8CO_2+10H_2O[/tex]
The balanced chemical equation for combustion of butane is :

Naval writes out the chemical equation for photosynthesis. She includes two reacting molecules to the left of the arrow and two resulting molecules to the right.
Light energy, above the arrow
Chlorophyll,to the left of the arrow
Enzymes, to the left of the arrow
ATP, above the arrow
Answer:
The question is incomplete. The remaining fragment that completes the question is: "What more must be added to the chemical equation to accurately represent photosynthesis? "
The answer is Light energy, above the arrow
Explanation:
Photosynthesis is a metabolic reaction unique to autotrophic organisms like plants, algae etc. It is the process whereby these organisms produce their food (glucose) using light energy from the sun.
Photosynthesis cannot occur without light, as the name implies: Photo- meaning light. The sun is the source of this light energy, which photosynthetic organisms like plants capture using a green pigment called CHLOROPHYLL.
Photosynthesis is a reaction with a general equation:
6CO2 + 6H2O ---light energy-----> C6H12O6 + 6O2
However, the energy needed to perform this reaction comes from light provided by the sun. Hence, Naval needs to put LIGHT above the arrow in her equation in order to accurately represent photosynthesis.

Puerto Rico, Cuba, Jamaica, and Hispaniola have species of anole lizards with distinct body types, including the grass lizards, which have long tails; the canopy lizards, which have large toe pads; and the twig lizards, which have short legs. Anole species with each of these three body types exist on each of the:_________
Answer:
four islands.
Explanation:
Anole lizards includes different types of lizards such as the canopy lizards, the grass lizards and the twig lizards and are found in Puerto Rico, Cuba, Jamaica, and Hispaniola.
Anole species with each of these three body types exist on each of the four islands because of interisland migration events.
The anole species share common ancestor with each other in comparison to other lizard species, interisland migration events allowed anole species to get evolved by natural selection process in different islands including Puerto Rico, Cuba, Jamaica, and Hispaniola.
Hence, the correct answer is four islands.

I want some hand with this please
1) One reason why deforestation is occuring because people need wood from trees to build things, therefore, leading them to cuting countless of trees.
2) One environmental problem that results from widespread deforestation is that the carbon dioxide they would normally use remains in the atmosphere, therefore, promoting erosion.
3) One way to lessen the effects of deforestation is by re-planting the cut-down trees and by cutting down less trees.

consider a molecule of the polymer, polyethylene, and a protein molecule as if they were strings of beads. How would the string representing polyethylene differ from that representing a protein
Answer:
When a macromolecule contains repeated similar sub units of a particular molecule:such a repeated units are called polymers.
Therefore, polyethylene is a micromolecule of repeated subunits called ethylene formed during polymerization..Therefore, the small units joined together to form polyethylene are ethylene.These are alkene hydrocarbons,which are similar in structure with the carbon atoms linked by double bonds.When the Pi bonds of the double bonds breaks. hydrogen atoms forms free covalents bonds in all these sub units.
However, polypeptides is made of of 20 different amino acids, connected by peptides, disulfide and other bonds.Therefore the protein molecules will be different from the polyethylene and polymers. This is because each of the 20 amino acids has different R-groups, and It is this R-groups that determine the functional characteristics displayed by each amino acid sub- units.Therefore, the characteristics of a protein molecule will be determine by the type of Amino acids it contains.
Thus the beads of polyethylene will be the same, but different in proteins
Explanation:
A scientist observes the motion of a certain type of vesicle around the cell. She notices that vesicle movement ceases when colchicine is added to the culture medium. What conclusion can she draw?
Answer:
colchicine inhibits microtubule function, it is most likely that the
vesicular movement is orchestrated or produce by microtubules.
Explanation:
Microtubules is organelle in the cell which give shape to the cell and help transport vessicles, granules and some organelles inside the cell.
Colchicine is a chemical substance that inhibit microtubules function and for gout treatment.
When colchicine is added to the microtubules, vessicles movement is produce by microtubules.

You are a pharmaceutical researcher trying to design a new drug for the treatment of cystic fibrosis. You are aware that an extracellular protein that is a chloride ion transporter is misfolded and never gets to the cell surface. You have a new undergraduate working with you. Explain which organelle is involved in this process and why the transporter protein is nonfunctional.
Answer:
Endoplasmic reticulum is the defective organelle in most CF.
Explanation:
This is because of mutation(deletion) in the proteins of these organelle. The CFTR protein -a transmembrane regulator get stucked inside the E.R, thus the CFTR chloride protein channel is blocked. Therefore the outflow of Cl and water out of the cell is obstructed.
Consequently, the mucus from blocked fluid flow, clogs the lungs, the fallopian tube, sweat duct, and other places.
