A . Leaves were trapped between layers of sediment millions of years ago, causing the imprint

Explanation:

The only true explanation that perfectly describes the rock is that the leaves were trapped between the layers of sediment millions of years ago causing the imprint.

Leaf imprints are often referred to as trace fossils.

  • Trace fossils points to the different life activities an organism must have been engaged in.
  • When a leaf is trapped in a soft sediment between two layers, the compaction of the sediment can duplicate the form of leaf on beds.
  • This gives a physical overview to the nature of leaf.
  • Such an imprint did not grow, and cannot be attributed to metamorphic processes(option D).
  • Option C is completely wrong

2. What does letter B represent on the Earthquake model?
Luda [366]

Answer:

A.

Explanation:

The letter B represents the Epicenter of the earthquake.

The focus would be the letter A and C would be called the fault.

The epicenter is the point closest to the point where the earthquake originated but on the surface and not underground. The hypocenter is the point within the earth where an earthquake rupture starts.

Duplication of a segment of a chromosome would result in _______. see section 16.4 (page 344) .
Svetlanka [38]
Duplications are repeated segments of genetic materials that result from unequal crossing over during meiosis or through a replication error prior to meiosis. They usually occur when homologous pairs do not line up correctly or in chromosomes with a lot of repeat sequences. Duplication of a segment of a chromosome would result in Genetic variability during evolution due to gene duplication.

Since her stomach was removed, Mrs. Lopez has the most difficulty initiating digestion of: Since her stomach was removed, Mrs. L
Svetllana [295]

Mrs. Lopez has the most difficulty initiating digestion of proteins after her stomach is removed. The correct option is C.

Explanation:

When the stomach is removed due to complications such as in cancers the food eaten directly goes to intestine. Without stomach Mrs Lopez will have difficulty in starting the digestion of protein.

The digestion of protein takes place and starts in the stomach and duodenum of intestine. There are enzymes as pepsin, trypsin and chyomtrypsin secreted  by stomach and pancreas. Pepsin breaks the peptide bonds of protein.

The HCl and the enzymes in stomach initiates the process of digestion of protein. The amino acids formed are ardent in various metabolic processes and repair.

lipids and carbohydrate digestion starts from the mouth only as salivary amylase and lipase initiates the process.
