In test tube B i.e., egg, albumin, pepsin and HCl the digestion of protein will occur as HCl will breakdown protein into simple molecules.
- Pepsin will be activated by HCl to break down proteins into their simpler constituents.
- Some enzymes, like pepsin in this instance, are activated by HCl in a catalytic manner.
- Gastric juice is a mixture of lipase, other digestive enzymes, and the least amount of diluted hydrochloric acid required for digestion.
- Pepsin, a digestive enzyme found in the stomach that aids in the breakdown of dietary proteins, is also present in this gastric fluid.
- Foods like milk, beef, and other dairy products are high in protein, which is broken down into smaller molecules for digestion.
- The pepsin is activated by the HCl in gastric juice. The protein intake is then catalyzed by the enzyme pepsin, which causes it to be broken down into smaller peptide molecules.

Order level of the taxonomic hierarchy is more inclusive than a family, but less inclusive than a class.
Order is the level that lies between the Class and Family. The example of Class Mammalia can be considered which consists of orders: Order Chiroptera, Order Primates, Order Carnivora, Order Cetacea, Order Insectivora, etc.
Taxonomic Hierarchy is the arrangement of all the organisms on the basis of their similarities or dissimilarities with other organisms. In the decreasing order, the levels of the taxonomic hierarchy include: Kingdom, Phylum/Division, Class, Order, family, Genus and Species. This categorization is essential to understand about the organisms as well as their relation with other organisms.

Answer:
During a concentric contraction, a muscle is stimulated to contract according to the sliding filament theory. This occurs throughout the length of the muscle, generating a force at the origin and insertion, causing the muscle to shorten and changing the angle of the joint.
<span>The correct answer, according to Lamarck's theory of evolution, is that A) "Land mammals progressively modified their organs to survive in water. These features were passed on to the next generation, and the mammal gradually evolved into today's aquatic mammals."
Lamarck believed that animals could (a) acquire the traits that they needed and (b) pass those acquired traits on to their offspring. According to part (a) of Lamarck's idea, if I needed to be a faster swimmer (if I were an athlete), I could modify my body to have webbing between my toes, which would allow me to beat the competition! Also, according to part (b) of Lamarck's idea, if I were a body builder and developed (acquired) very large muscles through my training, then my children should be born with very large muscles. Based on the these examples, you can see why Lamarck's theory of evolution is not the one that is generally accepted by scientists. Rather, Darwin's theory of evolution, in which the traits that we are born with confer either an advantage or disadvantage to us in our particular environment, which determine whether or not we are successful (ie, survive and reproduce). New traits come about randomly by mutation, not by our need for them.</span>
