Answer: The dead plants form the organic part of the soil. This is because when plants die off they become dirt and mulch which is good for the plants. This is why people make a big deal out of compost. It is because it is healthy and organic for plants.
Answer:
This is an example of scope creep.
Explanation:
In project management, scope creep signifies the changes, uncontrolled or continuous growth in the scope of a project, at any time after the initiation of the project. This can take place when the project's scope is not adequately documented, defined, or monitored.
The main reasons for scope creep are poor requirements analysis, underestimating the complexity of the project, not involving users early enough, and lack of change control. Thus, the given case is an illustration of scope creep.
The four levels of protein structure are distinguished from one another by the degree of complexity in the polypeptide chain. A single protein molecule may contain one or more of the protein structure types: primary, secondary, tertiary, and quaternary structure. 1. Primary Structure: describes the unique order in which amino acids are linked together to form a protein.
2. Secondary Structure: refers to the coiling or folding of a polypeptide chain that gives the protein its 3-D shape. There are two types of secondary structures observed in proteins. One type is the alpha (α) helix structure. This structure resembles a coiled spring and is secured by hydrogen bonding in the polypeptide chain. The second type of secondary structure in proteins is the beta (β) pleated sheet. This structure appears to be folded or pleated and is held together by hydrogen bonding between polypeptide units of the folded chain that lie adjacent to one another
3. Tertiary Structure: refers to the comprehensive 3-D structure of the polypeptide chain of a protein.
4. Quaternary Structure: is the structure of a protein macromolecule formed by interactions between multiple polypeptide chains. Each polypeptide chain is referred to as a subunit. Proteins with quaternary structure may consist of more than one of the same type of protein subunit.
Answer:
The given statement is true.
Explanation:
A condition in which uncharacteristically large, unusual and immature RBCs known as megaloblasts gets generated by the bone marrow is known as megaloblastic anemia. The condition can arise due to many causes of which deficiencies of folate or vitamin B12 (cobalamin) are the most general ones. The mentioned vitamins perform an essential function in the generation of RBCs.
The signs and symptoms of megaloblastic anemia are lightheadedness, shortness of breath, pale skin, unusual heartbeat, and dizziness. Some of the other signs of the condition are weakness in muscles, pains and aches, and dyspnea.
