The correct answer is (a) Bones.

The primary evidence of the existence of dinosaurs can be seen by the bones (fossils) that were found by scientists. Most of the fossils were found in badlands and deserts of China, North America and Argentina. By the studies of those fossils, more than thousands of dinosaur species are identified.

Answer:

The correct answer is B) "there is a close relationship between carbohydrate synthesis and carbohydrate metabolism".

Explanation:

The Calvin cycle are a series of chemical reactions that occurs in plant's stroma, and allow the convert carbon dioxide and other compounds into glucose in the absence of light. Most of the enzymes that function in Calvin cycle function as well in metabolic pathways,  because there is a close relationship between carbohydrate synthesis and carbohydrate metabolism. Particularly, gluconeogenesis and the pentose phosphate pathway have equivalent enzymes that those found in the Calvin cycle.

Other than bacteria, which factor leads to nitrogen fixation? A. Lightning B. Flood C. Rain
max2010maxim [7]

Answer:

A. Lightning

Explanation:

Nitrogen is very fundamental for a wide range of life activities in both plant and animals.

Lightning which accompanies thunder during rain storm and other weather phenomenon aids the release of atmospheric nitrogen for life processes. The energy that accompanies a lightning event is mostly electrical in nature. This electrical energy is huge and very massive. As the lightning interacts with free nitrogen molecules in the atmosphere, the molecule is broken down. The free nitrogen which results then combines with oxygen in the atmossphere to form oxides of nitrogen. When oxides of non-metals dissolves in rain water, they make the water rich in nitric acid and can be brought to the biosphere for use by plant and animals.

11. Explain the importance of having a cell's digestive enzymes enclosed inside lysosomes?
olya-2409 [2.1K]

Answer:

The low pH of the lysosome is maintained by membrane proteins that pump protons (H + ions ) from the cytosol into the lysosome. ... Although it may seem dangerous for cells to contain enzymes that can digest most biological molecules, the contents of the cell are doubly protected from the digestive enzymes of the lysosome.
