Answer:
Water added
Explanation:
The above option is the best that represents the missing step.
This process is known simply to be cellular respiration. It is also the reverse of photosynthesis.
In this process, food is broken down in a chemical reaction with oxygen. As this process occurs, carbon dioxide and water are the products. So, in this process, water is added as the product of the breaking down process.
Respiration is seen to be almost the exact opposite of photosynthesis. These two reactions help to maintain biological energy balance on earth.
Answer:
The answer should be the third explanation, which is "The experiment was subjected to both replication and repetition" because the question never provide information about the status of the scientists who conducted the experiment, the variables of the experiment, and whether or not a control group was included. The part where the question tells that many other scientists are doing the same experiments and obtaining similar results is the key to finding out the right answer,
Explanation:
The levels of protein structure that are most affected by chemically straightening the complex of protein that makes hair would be the quaternary and tertiary levels. This is because in this process, one would be disrupting many of the interactions that would be occurring between the R groups of the protein, including hydrogen bonding and other van der waals forces.
These interactions can affect more than 1 polypeptide chain as well and thus the quaternary is also affected.
Hair will not remain straight as after the reagent or other substance is removed the hydrogen bonds will again reform and the R groups will orient themselves to maximize interactions.
The remains of the living organisms used in understanding the history of life on Earth is fossils.
Fossils are the preserved remains of plants and animals whose bodies are buried in sediments such as sand and mud under ancient seas, lakes and rivers.
Fossils are the geologically altered remains of once-living organisms and/or their behavior. There are mainly two types of her: Body fossils represent all or part of an organism's body, while vestigial fossils show an organism's behavior.
Fossils form in a variety of ways, but most often form when living organisms (such as plants or animals) die and are quickly buried by sediment (such as mud, sand, or volcanic ash).
Fossils are found mainly in river valleys, cliffs and hills where sedimentary rocks of appropriate age are exposed, and in areas of human exposure such as quarries and road cuttings.
