<span>The resulting movement is scapular protraction and rotation.The scapula is moved along the chest wall. The muscles involved in this process are the serratus anterior, which is the prime mover. Pectoralis minor and major, the latter acting through the humerus, may assist (act as synergists).</span>
Answer:
Option c
i think so because mechanical digestion and protein digestion is completed in small intestine and i am not sure about lipid breakdown but i think that it is also completed in small intestine
Explanation:
Answer:
d. Genes that play a role in the same metabolic pathway are organized into an operon.
Explanation:
In prokaryotic organisms like bacteria, polycistronic mRNAs exist which means that each gene does not have a separate promoter of its own. In fact many genes are under the control of a single promoter. These genes being a part of same metabolic pathway are organized into an operon. For example, lac operon and tryptophan operon. In lac operon, three genes named as β-galactosidase, permease and transacetylase are expressed under a single promoter which is known as lac promoter.
In contrast to this, in eukaryotes the mRNAs are monocistronic i.e. only a single gene is controlled under a single promoter.
Answer:
Let assume one of option is - decreasing adhesive forces in between the water molecules and the glass due to mineral solution.
Explanation:
Adhesive force is the attraction of two different types of atoms or the molecules of unlike substances. Water and glass molecules are not similar as water is not having charged molecules like the glass molecules. Water molecules are attracted to glass molecules that are charged due to adhesive force.
Treating the glass with mineral solution decreases the adhesive force which leads to forming drops instead of the puddle.
Thus, the correct answer is -decreasing adhesive forces in between the water molecules and the glass due to mineral solution.
