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).
PLZ HELP!!! ILL MARK BRAINLIEST!!! Would you consider the practice of "ghost hunting” to be closer to science or pseudoscience, based on the information provided in the article? Provide two examples to support your answer.
Answer:
I would consider the practice of "ghost hunting” to be closer to pseudoscience than science because the work described in the article mostly lacks process and is subjective. In the article, people looking for evidence of ghosts do not set up controlled experiments with repeated trials. Instead, they take several measurements and make guesses about what might be causing the results they see. The people in the article also base conclusions on observations such as feeling a "heavy presence” or a "sudden chill.” These are subjective observations.

Is Coca Cola a homogeneous mixture
Answer:
Yes
Explanation:
Coca Cola is a homogenous mixture, just like sugar, salt, and more. Hope this helps!
Answer: Yes
Explanation: Coca cola is a homogeneous mixture because the syrup and water are mixed evenly throughout the solution. For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture. Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture.

Which skill involves creating representations of complex objects or processes? A. classifying B. predicting C. making models D. evaluating (this is probably really easy, but my mind is going blank)
Answer:
C. making models
Explanation:
Making models facilitates constructing depictions of complex objects or practices that enable students to practice and understand how things work which can not be observed and measured directly. Model making needs abstract thinking about the tools and material used, spatial thinking, and well-organized idea of the project to create complex objects.

Classify the following pieces of matter:
bronze
pure water
tap water
trail mix
Answer:
bronze - solid
pure water - liquid
tap water - liquid
trail mix - solid
Explanation:
There are 4 classes of matter based on the characteristics of their molecules:
SolidsLiquidsGasesPlasmaThe molecules in solids are tightly packed together and are more or less fixed about a point with very little of no movement. The molecules in liquids are less tightly packed and are able to take the shape of their containers. The molecules in gases are loosely packed and compressible. They can take the shape of containers as well as expand to a container due to their loosely packed molecules.
Plasma molecules neither have shape nor volume but are able to produce both magnetic and electric currents as well as respond to electromagnetic fields.
Hence bronze has all the characteristics of a solid, pure and tap water both have the characteristics of a liquid, while trail mix can be considered a solid.

How does increased temperature affect the amount of salt, carbon, and other substances able to dissolve in the ocean? What are the resulting effects?
Answer:
For solid salts that are soluble in the sea water, as the sea water temperature rises, the solubility of the salt in the water increases. The accompanying increase in the kinetic energy of solvent water molecules with the increase in the temperature of the seawater results in the increase in the number of solute salt inter-molecular bonds being broken by the energetic solvent molecules resulting in increasing solubility of the solids
However, for gases, the increase in temperature of the sea water results in a decrease in the solubility of all gases. The process is also explainable by the kinetic theory such that a rise in temperature of the gas seawater solution increases the kinetic energy of both the solvent water and the solute gas. The higher energy gases are moving much faster and are then then able to separate from the less mobile liquid gas combination.
The resulting effects
1) The surface (topmost) hotter portions of the sea have fewer living organisms
2) Fishes that come to the surface frequently gas for air by bringing their head above water
3) Most of the life forms are located deep within the sea
4) Formation of water movement cycles within the ocean and polar water bodies
5) Mechanical nature of the sea compared to fresh water bodies

What is the connection between Archimedes and the Mass-Volume lab
Answer:
Explanation:
This question is not very clear, however, going by the key words in the question, Archimedes' principle shows a relationship between mass and volume.
Archemedes' principle states that when a body is fully or partially immersed in fluid, it is acted upon by an upward force which is equal to the weight of the fluid displaced by the body.
The volume displaced here can be determined using the formula
Density of liquid = mass displaced ÷ volume
Hence, volume = mass displaced ÷ density of liquid

Please answer asap!! how does the density of an object identify the material the object is made from?
Answer:
If you were to divide any object into small pieces of unit volume, the density would be the mass of each small piece. Everything is made up of molecules, which in turn are made up of atoms. So every object is created from the aggregation of atoms and molecules.

mass = 54 g
volume = 20 cm³
Substitute the values into the above formula and solve for the density
That's
[tex]Density = \frac{54}{20} [/tex]We have the final answer as
Density = 2.7 g/cm³Hope this helps you

how many grams of oxygen are in 25 grams of sugar?
Answer:
13 grams of Oxygen
Explanation:
Step 1: Find molecular formula of sugar
C₁₂H₂₂O₁₁
Step 2: Convert moles of oxygen present to grams
1 mol O = 16 g O
11 mol O = 176 g O
Step 3: Find molar mass of sugar
C - 12.01 g/mol
H - 1.01 g/mol
O - 16.00 g/mol
12.01(12) + 22(1.01) + 11(16.00) = 342.34 g/mol C₁₂H₂₂O₁₁
Step 4: Set up dimensional analysis
[tex]25 gC_{12}H_{22}O_{11}(\frac{176 gO}{342.34gC_{12}H_{22}O_{11}} )[/tex]
Step 5: Multiply/Divide and cancel out units
Grams of C₁₂H₂₂O₁₁ and grams of C₁₂H₂₂O₁₁ cancel out.
We are left with grams Oxygen
25/342.32 = 0.073031(176) = 12.8535 grams Oxygen
Step 6: Simplify
We only have 2 significant figures in this problem. Thus,
12.8535 = 13 g O

he Solids model formed by atoms as solid spheres for macroscopic measurements, the model has no problems, because the atoms are extremely small
Dalton's atomic model was the first scientifically based model formulated in 1808, it consists of atoms with spheres that cannot be divided and solids are formed by contact between the spheres and chemical compounds are formed by joining atoms of two or more elements, this model is used to approximate solids such as solid spheres there are today.
The size of these spheres (atoms) is very small, nowadays it is known that it is of the order of 10⁻⁹ m, therefore, having a macroscopic crystal more than 10⁻⁶ m in length, it is impossible to measure fluctuations in the sizes of the spheres, since there are 10⁹ spheres in this volume, therefore it is not possible to measure the fluctuations with instruments,
To be able to measure this fluctuation, very small samples and very high resolution transmission microscopes are needed.
In conclusion, the model of the atom as solid spheres for macroscopic measurements, the model has no problems.

What is the solution for x in the equation? -3x + 7x − 8 = 34 + 9x − 2
Answer:-8
Explanation:
edmentum
The solution for the given linear equation can be solved by simplifying the equation. The value of x is obtained as - 8.
What is linear equations?Linear equations are the equations which shows a linearity with a second expression which is similar to the first but having different mathematical operations and signs.
By solving linear equations we can solve for the unknown value of x. The value of x can be obtained by taking the whole expression to one side and which is having a constant value.
Given, - 3x + 7x - 8 = 34 + 9x -2.
= 4x - 8 = 32 + 9x
= 4x - 8 - 9x = 32
-5x = 40
x = - 40/5 = - 8.
Hence, solution of the given equation is -8.
