12. Cows digest proteins into smaller molecules called peptides through the use of an enzyme called pepsin.
Aqueous solutions taken from the contents of a cow's stomach are found to have many more hydrogen ions
(H+) than hydroxide ions (OH-). A veterinarian is attempting to conduct an experiment that mimics protein
digestion and has the following four test tubes set up. Which would you expect to have the greatest
concentration of peptides?
(A) Test tube 1: protein and pepsin in water at pH 1.4
(B) Test tube 2: protein and pepsin in water at pH 8.2
(C) Test tube 3: protein in water at pH 7.6
(D) Test tube 4: pepsin in water at pH 1.7

Answers

The correct answer would be answer choice A!!!! The reasoning for this is that free H+ ions in a solution DECREASE the pH or in other words make the solution more acidic. So because of that we know that our solution must have a lower pH so we know the correct answer is either A or D because these are acidic solutions. In order for pepsin to catalyze the reaction there must be protein present and because of this we can eliminate answer choice D. So answer choice A is correct.

explain what density is. How is it different from weight and mass?

Answers

Hey there! I'm happy to help!

Density is how much mass there is per amount of space. The formula for it is mass divided by the volume. How much mass is there per (per means divide) amount of space?

Think of it like a room in a house. If the room only has one person, it isn't going to be very dense with people because there is only one person in the entire room. If there were 100 people, it would be very crowded in that room and the whole room would weigh a lot more. If we make our room the size of a huge convention hall though, 100 people wouldn't make it very crowded,. and it would be less dense. So the amount of people (mass) and the size of the room (volume) affect density.

In that sense, density is kind of like how crowded a thing is.

A hollow watermelon has less density than one that isn't because a watermelon that isn't hollow has more substance inside of it (more mass).

Mass is a factor of density because it measures how much of something there is. It can be related to the people in the room.

Weight is mass but with gravitational influence. A watermelon in space is going to weigh less than a watermelon on Earth because in space there is no gravity and it is floating around, but it will still have the same density just like our room full of people would still be crowded even if the people weighed nothing and were floating around.

On Earth though, we measure mass with terms like pounds, kilograms, etc. We use the term mass over weight because it is more scientifically accurate when calculating density.

Have a wonderful day and keep on learning! :D

Density quantifies how much mass is present in a certain matter or object with respect to volume

The image shows a vulture soaring over a rocky cliff. The arrows model the different ways energy moves between the sun, atmosphere, and geosphere.

Match each type of energy transfer to the arrows shown in the image. Describe how energy transfer helps the vulture soar above this rocky cliff.

Answers

Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.

The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.

Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.

The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.

Which of the statements below correctly compares features of plant and animal cells?

Plant cells have ribosomes only on the rough ER, while animal cells have ribosomes in the cytoplasm.
Plant cells have a large central vacuole, while animal cells have many smaller vacuoles.
Plant cells have chloroplasts but no mitochondria, while animal cells have mitochondria.

Answers

Plants cells have a large central vacuole, while animals cells have many smaller vacuoles

Plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

What are vacuole?

Vacuole is defined as a region of cytoplasm-free, membrane-lined, and liquid-filled space inside a cell. A membrane-bound cell organelle known as a vacuole.  The plant cell's equilibrium depends heavily on the vacuole. It participates in the regulation of cytoplasmic ions, pH, and the control of cell volume and turgor.

Animal cells lack a cell wall, whereas plant cells do. Animal cells lack chloroplasts while those of plants do. Animal cells have many little vacuoles, but plant cells only have one giant vacuole. Animal cells only have a cell membrane, but plant cells have both a cell wall and a cell membrane. Cell walls are used by plants to give the plant structure. Animal cells lack the organelles known as chloroplasts that are present in plant cells.

Thus, plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

Sodium is not a functional group that can bond with carbon (Option C)

A functional group is a combination of atoms in a molecule that is capable of conferring particular chemical and physical properties.

The most common functional groups include the carboxylic acids groups (CO2H),  carbonyl groups (C=O), alcohol groups (-OH), ester groups (CO2R), and amine groups (NH2).

Functional groups are observed along the carbon backbone of the biomolecules.

This carbon backbone is made up of chains/rings of carbon atoms with the occasional substitution of an element (e.g., N or O).

In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.


The samples that were loaded into each of the four lanes are as follows:

Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested
