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.

Answers

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).

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

Plant cells have a cell membrane, while animal cells have both a cell wall and a cell membrane.
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.

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.

What similarities, if any, do you think exist between a human’s reproductive cycle and the life cycle of a fern? What differences, if any, can you think of?

Answers

Answer:

The similarity between ferns and humans is that both go through meiosis and mitosis. But ferns are different because they have multicellular, free-living haploid and diploid forms. In humans, the haploid stage exists in the form of single cells—sperm and eggs. Only the diploid stage that begins with a zygote grows mitotically to form a multicellular, free-living human.

Explanation:

Humans and ferns are similar as both of these organisms fertilize to reproduce while differs in the haploid form of life which is present in the ferns and the male and female reproductive parts present in humans.

 

What is the life cycle of a fern?

The life cycle of fern includes the diploid fern which gives rise to the haploid spores that grows and form a gametophyte plant in which both the male and female reproductive systems are present. The male gamete undergoes fertilization with the female gamete to form a diploid spore (seed) which gives rise to the new fern plant.

Human’s reproductive cycle include diploid animals and the male and female genders which can be distinguished clearly. The male gamete-sperm fertilizes with the female gamete-egg to form the diploid zygote that gives rise to a new human.

What is climate change ?

Climate change is the long term change in the Average weather conditions of a region, province or territory. Climate change is associated to global warming caused by the activities of man which affects the weather conditions of a given region in the long term.  

As the climate continues to change, many organisms begin to redistribute themselves to regions with favourable weather conditions, and this is the biological prediction/effect of climate change on the environment.

Hence we can conclude that The distribution of many organisms has already shifted as a result of warming  is the correct statement.
