The polypeptides are broken down into amino acids by the process of hydrolysis. Hydrolysis is the process by which most of the polymers break down into monomers.
Polypeptides are the compounds which are made up of amino acids. These are the polymers which are formed by the polymerization of amino acids through peptide bonds.
Amino acids form proteins by undergoing polymerization to form polypeptides which form proteins. These polypeptides can be broken down into simple amino acids by the process of Proteolysis.
Proteolysis is the process of breakdown of proteins into smaller polypeptides or amino acids. The hydrolysis of peptide bonds is an extremely slow process which takes hundreds of years. Proteolysis is a catalyzed reaction by the cellular enzymes called proteases, but this breaking down of polypeptides into amino acids may also occur by the intra-molecular digestion.

As a child, Alex was short for his age. But during his teenage years, his height increased and he surpassed most of his friends. What must have occurred to create this growth spurt? A.Cells in Alex’s body underwent meiosis to create new tissue.
B.Cells in Alex’s body underwent mitosis to create new tissue. C.Cells in Alex’s body produced haploid cells that formed new muscle. D.Cells in Alex’s body produced new tissue by budding.
The answer would not be A. I got it wrong on Plato.
Ans. (B).Cells in Alex’s body underwent mitosis to create new tissue.
Mitosis is defined as a type of cell division, which is associated with the growth, development, and repairing of damage tissues. During mitosis, one parent cell gives rise to two identical daughter cells. As mitosis increases the cell numbers and makes new tissues, it is responsible for growth and development of the body.
Thus, the correct answer is option (B).

What ethical issues could arise from using embryonic cells as opposed to adult stem cells?
Stem cell research offers great promise for understanding basic mechanisms of human development and differentiation, as well as the hope for new treatments for diseases such as diabetes, spinal cord injury, Parkinson’s disease, and myocardial infarction. However, human stem cell (hSC) research also raises sharp ethical and political controversies. The derivation of pluripotent stem cell lines from oocytes and embryos is fraught with disputes about the onset of human personhood. The reprogramming of somatic cells to produce induced pluripotent stem cells avoids the ethical problems specific to embryonic stem cell research. In any hSC research, however, difficult dilemmas arise regarding sensitive downstream research, consent to donate materials for hSC research, early clinical trials of hSC therapies, and oversight of hSC research. These ethical and policy issues need to be discussed along with scientific challenges to ensure that stem cell research is carried out in an ethically appropriate manner. This article provides a critical analysis of these issues and how they are addressed in current policies.
Water molecules are ____________ due to _________bonding. This property helps water molecules to stick to each other and allows for the movement of water from plant roots up to plant leaves
Answer: cohesive , hydrogen
Explanation: Cohesion is the force of attraction between similar molecules. Water molecules are cohesive due to hydrogen bonding. This property of water allows the molecules of water to stick to each other.
Water forms hydrogen bond due to the presence of hydrogen atom and a electronegative oxygen atom. The formation of hydrogen bonds leads to the cohesive nature of the substance allowing plants to transport water from their roots up through stems to their leaves due to capillary action which is also a result of hydrogen bonding.

During summer, cities located near the coast are ________ than those in the interior at the same latitude, while in the winter they are ________.
Answer:
Cooler, Warmer
Explanation:
The ocean water bodies has the high heat capacity as a result of which the oceans and seas are heated and cooled at a much slower rate, in comparison to the land areas. The places that are near to the ocean bodies generally experiences a cooler type of temperature during the day time and it gradually increases as one moves away from the oceans towards the inland areas.
The ocean has the capacity to store heat during the summer season, and it eventually releases during the winter. This cycle repeatedly occurs, as a result of which during winter, the cities near the coast are usually warmer and on the other hand, these cities are colder during summer.
What hormone is released during stressful situations often causing a spike in hunger?
The male structure, known as the _____, is comparable to the ovaries in females.
Hilda and her family are going on a sailing trip this summer, and Hilda is especially interested in spotting dolphins. In which zone of the ocean is Hilda most likely to spot dolphins? Hilda and her family are most likely to spot dolphins in the (BLANK )zone. To view shorebirds and crabs, Hilda should move towards the (BLANK) zone
The first blank can be filled with the pelagic zone and the second blank can be filled with the intertidal zone.
The pelagic zone comprises the water column of the open ocean and can be further differentiated into the regions by depth. Dolphins are witnessed in the pelagic zone of the ocean. The intertidal zone also called littoral zone, refers to the region of the seabed and foreshore, which comes into contact with the air at low tide and submerged at high tide, shorebirds and crabs are witnessed in this zone.
The nurse is assigned to watch the cardiac monitors in the constant care unit and notes four different clients displaying arrhythmias. which arrhythmia is the nurse's highest priority
The nurse’s highest immediate priority is ventricular fibrillation (VF) due to its life-threatening nature. Sinus bradycardia, atrial flutter, and sinus tachycardia, are generally less immediately critical. Option D is correct.
This is because VF is a life-threatening condition where the heart's electrical activity becomes disordered, causing the ventricles to quiver ineffectively instead of pumping blood. Immediate action is required as VF can lead to cardiac arrest and sudden death if not treated promptly.
Here are brief explanations for why the other arrhythmias are less immediately critical:
Sinus bradycardia at a rate of 54 beats/min: This is generally not symptomatic unless the patient shows signs of weakness, fatigue, or dizziness.Atrial flutter: Although it needs treatment, it doesn't usually result in immediate life-threatening situations.Sinus tachycardia at a rate of 108 beats/min: While this is abnormal, it often requires addressing the underlying cause rather than immediate emergency intervention.Complete question as follows:
The nurse is assigned to watch the cardiac monitors in the constant care unit and notes four different patients displaying arrhythmias. Which arrhythmia is the nurse's highest immediate priority?
A) Sinus bradycardia at a rate of 54 beats/min
B) Atrial flutter
C) Sinus tachycardia at a rate of 108 beats/min
D) Ventricular fibrillation

Cilia and flagella differ from each other primarily in
Final answer:
Cilia are short, numerous structures on a cell's surface designed to move cells or substances on a cell's surface, while flagella are fewer and longer, used to propel the cell itself. Despite these differences, both have a similar '9 + 2 array' microtubule structure that facilitates movement.
Explanation:
Cilia and flagella differ from each other primarily in terms of their length and number on a cell's surface. Cilia are short, hair-like structures and are found in large numbers along the entire surface of the plasma membrane. They can move entire cells or substances along the outer surface of the cell, like in the lining of the Fallopian tubes or the respiratory tract. On the other hand, flagella are long, hair-like structures that extend from the plasma membrane, typically with just one or a few per cell, and are used to move the entire cell itself, as seen in sperm cells or certain microorganisms like Euglena.
Despite these differences, both cilia and flagella share a common structural feature known as the "9 + 2 array" of microtubules. This describes the arrangement where a ring of nine microtubule doublets surrounds a pair of single microtubules at the center. This shared structure underlies their ability to perform their locomotive functions.

The most common type of distribution pattern(s) in nature is(are) _______.
Answer:
The given blank can be filled with cluster.
Explanation:
The most general pattern of distribution in nature is clustered. This is because the resources are distributed intermittently in the environment. Thus, if the resources are rare, or because of the social element, the individuals would cluster together in the region where these factors become auspicious.
The least common kind of distribution pattern is termed as the random distribution, and it is evident in homogenous surroundings that are very rare. The other kind of pattern known as regular distribution is the outcome for direct social associations amongst the individuals within the population, or for a resource.

How do cells such as algae and protists avoid lysis in fresh water?
Final answer:
Cells like algae and protists avoid lysis in fresh water by using contractile vacuoles to expel excess water and by actively adjusting their internal solute concentrations.
Explanation:
Cells such as algae and protists avoid lysis in fresh water through several mechanisms to manage osmotic pressure and maintain water balance. The presence of a contractile vacuole is a critical adaptation in many freshwater protists, such as paramecia. This specialized vacuole functions to expel excess water that enters the cell via osmosis, due to the higher solute concentration inside the cell compared to the surrounding fresh water. This process involves the contractile vacuole collecting water from the cytoplasm via its surrounding canals, and then, when full, pumping the water out of the cell through a specialized pore. Additionally, some protists can adjust their internal solute concentrations by actively pumping salts in or out of the cell, a strategy that helps in coping with changes in environmental solute concentrations.
