BiP is found in high concentration in the lumen of the ER but is not present in significant concentrations elsewhere in the cell. How do you think this condition is established and maintained
Answer:
Initially, endoplasmic reticulum plays a key role in the production of protein, while BiP found in the endoplasmic reticulum contains Lysine , Aspartic acid , Glutamic acid and Leucine sequence. All these, cause BiP concentration to remain high in the ER (endoplasmic reticulum) hence retained. Making the lumen always concentrated on BiP.
Explanation:
BiP is known as binding protein, that binds two or more molecules together and is found in the endoplasmic reticulum at the lumen due to the absence of glucose.
The endoplasmic reticulum found in fungi cells, plant cells, animal cells, and protists cells, makes and processes proteins.
Lysine , Aspartic acid , Glutamic acid and Leucine sequence ensures the protein concentration is protected in the endoplasmic reticulum (ER).
In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is
Answer:
c) 0.10M NaCl
Explanation:
Options are:
a) 0.20M NaCl
b) Very acidic
c) 0.10M NaCl
d) 0.10M HCl + 0.20M NaOH
e) Slightly acidic.
Based on the reaction:
NaOH + HCl → H₂O + NaCl
You can see than 1 mole of NaOH reacts per mole of HCl producing 1 mole of NaCl
Assuming 1L of 0.20M HCl reacts with 1L of NaOH, moles of both compounds are:
1L * 0.20mol/L = 0.20 moles reacts. That means moles of NaCl produced are 0.20moles in 2L. Molarity of NaCl is:
0.20mol / 2L = 0.10M NaCl
That means, right option is:
c) 0.10M NaClAt the equivalence point, 0.01 M NaCl is present.
The reaction between NaOH and HCl occurs as follows;
NaOH(aq) + HCl(aq) ------> NaCl(aq) + H2O(l)
Concentration of HCl = 0.20 M
Concentration of NaOH = 0.20 M
Let as assume that the volume of both solutions is 1 L each
Number of moles of HCl = 0.20 moles
Number of moles of NaOH = 0.20 moles
The reaction is 1:1 hence 0.20 moles of NaCl is formed. However, the volume of the solution is now 2L.
Concentration of NaCl = 0.20 moles/2L = 0.01 M
Missing parts;
In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is
Select one:
a. 0.20 M NaCl
b. very acidic

Victoria grows the same bacteria in 20 petri dishes. She places 10 of the dishes in a container with a normal atmosphere. The remaining dishes she places in a container in which the oxygen level is double the normal level. She labels the first group "A" and the second group "B." Which statement best describes the groups?
Answer:
There are no options but the question can be answered based on general understanding of experimentation.
Group A: Control group
Group B: Experimental group
Explanation:
In an experiment, there are two groups viz: the control group and the experimental group. A control group is the group that does not receive any experimental treatment. It is considered the normal group while the experimental group is the group that is subjected to experimental treatment.
N.B: The experimental treatment in this case is the "Oxygen level"
According to the question, out of 20 petri-dishes used to grow bacteria, half (10) of the petri-dishes were placed in a container with normal atmosphere while the other 10 petri-dishes were placed in another container that have double the normal oxygen level. The first group of bacteria labelled GROUP A are the CONTROL GROUP because they were not given any treatment i.e placed under normal conditions while GROUP B are the EXPERIMENTAL GROUP because they are the group that received the experimental treatment (increased oxygen level).

"What quantitative measurement and qualitative observations can be made about the interactions of matter and energy?" can someone break this down for me?
Quantitative measurements are numerical values, they involve amounts and units like measuring things. Qualitative observations appeal to the five senses, like what does the interaction look and sound like
Quantitative measurement about the interactions of matter and energy significantly deals with the representation of numerical values and data.
What is Matter?Matter may be defined as any sort of substance that is constructed of numerous types of particles that occupy physical space and possess inertia. In simple words, matter may be characterized as anything which occupies space and has mass.
The Qualitative observation of the interactions of matter and energy prominently deals with the concept based on perception. It basically involves all sorts of senses that one should occupy.
For example, how does the interaction between matter and energy looks like in appearances, heared through sounds, and feels through external factors.
Therefore, quantitative measurement and qualitative observations can significantly be made about the interactions of matter and energy.

(1) • Balanced Equation : 2HgO (s) ---> 2 Hg (l) + O₂ (g)
• Line a is represented by activation energy, or the smallest amount of energy needed for molecules to undergo a chemical reaction.
• Activated complex is the intermediate state during the conversion of reactants into products. In this case it is represented by Hg----O-----O----Hg. The dashed lines indicate that the bond between Hg and O are breaking and their length is increasing and the dashed line between oxygen atoms indicate that the bond is decreasing and bond formation is taking place.
• This reaction is endothermic as the energy of reactants is smaller than the energy of products.
(2) • Balanced Equation : CH₃Br + OH⁻ ---> CH₃OH + Br⁻
• The hydroxide ion reacts with the bromomethane, resulting in a double replacement reaction. The 'CH₃' in 'CH₃Br' joins with the hydroxide ion to form CH₃OH, while the Br breaks off as an ion.
• Take a look at the energy diagram below.
If you want to cause an object to move, what should you do?
Answer:
For an object to move, there must be a force. A force is a push or pull that causes an object to move, change direction, change speed, or stop. Without a force, an object that is moving will continue to move and an object at rest will remain at rest.

A pure sample of a hydrocarbon is found to be 74.5% carbon by mass. What is the empirical formula of this compound?
Answer:
THE EMPIRICAL FORMULA FOR THE PURE HYDROCARBON IS CH4
Explanation:
A pure hydrocarbon contains carbon and hydrogen
Percentage composition of carbon = 74.5 %
Percentage composition of hydrogen = 25.5
In order to calculate the empirical formula of this hydrocarbon, you follow these couple of steps.
write out the percentage composition and divide by the relative atomic mass of the respective constituents.
Carbon = 74.5 / 12 = 6.2083
Hydrogen = 25.5 / 1 = 25.5
Next is to divide the values by the lowest factor
Carbon = 6.2083 / 6.2083 = 1
Hydrogen = 25.5 / 6.2083 = 4.1
Next is to write the empirical formula:
C H4
In conclusion the empirical formula for the pure hydrcarbon is CH4
