Other joints consist of bone ends held together by hyaline cartilage or fibrocartilage. These are classified as cartilaginous joints, which are amphiarthrotic or slightly movable joints.
A cartilaginous joint is formed when two bones are joined together by cartilage, a rigid but somewhat flexible form of connective tissue. These joints do not have a cavity and are made up of bones connected around each other by either fibrocartilage or hyaline cartilage.
Amphiarthroses are slightly movable joints. Amphiarthrosis is the singular form. The bones in this joint are held together by fibrocartilage or hyaline cartilage. The costal cartilages that connect the ribs to the sternum are slightly movable joints attached by hyaline cartilage.

Salivary glands produce large amounts of enzymes, such as amylase, that are secreted out of the cells . Which of the following explanations best fits abundance of certain organelles over others in these cells ?
Answer:
Sorry if this doesn't help, but I believe the answer would be
"ribosomes".
(I'm not experienced in this subject but I hope I could help!)
Salivary glands produce large amounts of enzymes, such as amylase, that are secreted out of the cells. Ribosomes are the organelles which are more abundant in cell over others. Thus, the correct option is B.
What are Ribosomes?Ribosome are the cell organelles which are abundant in the cells over the other organelles. Ribosomes are found attached to the surface of the Endoplasmic reticulum, these structures are called Rough Endoplasmic Reticulum (RER).
Ribosomes are the cellular machinery which are responsible for making proteins through the process of translation. There are many ribosomes in each cell, which are made up of two subunits. These two subunits include one large and one small subunit which lock around the messenger RNA (mRNA) and then travel along the length of the mRNA molecule reading each three-letter codon which encode different amino acids and hence proteins.
Therefore, the correct option is B.

Under anaerobic conditions, how do cells regenerate atp?
a) fermentation aerobic
b) respiration glycolysis, & creatine phosphate
c) pathway creatine
d) phosphate pathway
Option B: Under anaerobic conditions, cells generate ATP through anaerobic glycolysis and creatine phosphate.
Our body produces ATP through oxidative phosphorylation. ATP is used in various functions and gets hydrolyzed into ADP and inorganic phosphate. But during intense exercises like sprinting, our body becomes unable to produce sufficient ATP through oxidative phosphorylation.
In this condition, creatine phosphate is used to regenerate ATP molecules for a short time. Creatine phosphate, when short of oxygen, transfers high-energy phosphate to ADP. ADP then gets transformed into ATP and produces creatine out of the reaction.
Another mechanism to produce ATP when short of oxygen is through anaerobic glycolysis. In this method, glucose is converted to lactate. This is a faster mechanism that produces 2 molecules of ATP per glucose molecule. The energy produced through oxidative phosphorylation is 100 times slower than anaerobic glycolysis.

Explain how bacteria affect the water-holding and nutrient-holding capacity of soil?
Bacteria improve the nutrient holding capacity of the soil as they perform nutrient cycling as well as decomposition of dead and decaying matter that increases the nutrient richness of the soil. The water holding capacity is improved by the formation of aggregates of soil that hold the water molecules efficiently.
Nutrient cycling is the process in which a nutrient follows a specific path repeatedly and benefits the living organisms in the process. The pathway generally includes of both, the living as well as the non-living factors. The various nutrient cycles that run in the nature are: carbon cycle, sulfur cycle, nitrogen cycle, etc.
Decomposition is the process of decaying of the dead organic matter of plants or animal that results in the transfer of nutrients from the dead organic matter to the soil.

What is chargaff's rule?The molar ratios [A] = [T] and [C] = [G] were present in all species, and the ratio [C + G] / [A + T] was often lower than unity since [C + G] is a less common element. And Chargaff's rule name is given to these ratios.
Additionally, the molar similarities of A with T and C with G naturally support a certain type of combination link. Furthermore, Chargaff himself is unwilling to take a chance on claims of his experimental observation in the absence of new experimental ideas.
Additionally, he believed that Watson and Crick's model-building strategy was not grounded in science. Most notably, he later disparaged molecular biology in general and eventually grew frustrated at what he perceived as a refusal to acknowledge the significance of his work.
Therefore, in this case, 30% is Adenine and 30% will be Thymine, so the remaining 40% will be GC, out of which 20% will be Guanine.
