When animals and plants die, their bodies fall into sediments. Some of these decays while some become part of fossilized rocks. Rock layers build up and the rock becomes a solid. The minerals in the rock replace the soft parts in parts of dead bodies. This takes place over millions of years. The remains of living organisms that have changed to stone are fossils.
Explain the importance of proteins in our body
It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions.
Addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
Suppose you were interested in the effect of breastfeeding versus formula feeding on the composition of gut flora in newborns. As part of your experiment, stool samples from healthy babies in the study get plated on various agar media. You notice that greater numbers of colonies are recovered when samples are plated on blood agar compared to nutrient agar (NA). After some diligent subculturing, you isolate several bacterial species capable of slow growth on the blood but not on the NA. You correctly surmise that these organisms: ______________
a. are opportunistic blood pathogens.
b. have extensive and complex nutritional requirements not met by NA are inhibited by the ingredients in NA.
c. should be classified as beta-hemolytic.
d. grow because the blood agar suppresses the growth of faster-growing bacteria.

What type of energy is used? Photosynthesis transforms ___________ energy into ___________ energy in ___________ molecules.
Answer:
Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
Explanation:
During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.
----------------------------------------------------------------------------------------------
During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.
ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.
ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.
The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.
These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).
ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.
Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.
Chlorophyll molecules entrap solar energy . There are 2 types of photo systems in chlorophyll. These are photo-system -I and photo-system-II .
The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.
During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.
Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.
The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.
Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.

What are the 3 parts of the digestive system? What does each one do?
Answer:
The Esophagus, Gastric Chamber and Intestines
Explanation:
esophagus pushes chewed food to stomach by peristalsis. The gastric chamber(stomach) works on digesting the food. The digestion completes in the small intestine and goes through the large intestine which absorbs water and minerals. Then it passes through the Anus and get pooped out.
