Biologists and Geologists use scientific knowledge to answer questions and solve problems affecting the natural world.
Biologists specialize in the study of living things. Geologists are considered physical scientists since they study the earth. Geology and biology are generally unconnected areas, despite the fact that they are both natural sciences, or studies that investigate the physical universe.
Scientific knowledge is what Biologists and Geologists gain from the experimental and data-gathering phases of the scientific method. Data gathering for scientific research is done in order to study and understand a phenomenon with help of which questions are answered and problems are solved.
While biology is the study of living things and rocks are not live things, geology is the study of rocks. A biologist, however, may find geologist information beneficial, and vice versa.

how can microscopes help you see cells? first, think of a. good place to collect a sample of cells
Microscopes helps to see cells by magnifying the sample using the different magnification strength of lens.
Microscopes- A laboratory tool called a microscope is used to look at items that are too tiny to be seen with the human eye. The study of tiny objects and structures under a microscope is known as microscopy. The microscope has 4 objective lenses: Scanning (4x), Low (10x), High (40x), and Oil Immersion (100x).
Cell- The analysis of structure and function of cells is known as cell biology, and it is based on the idea that a cell is the basic building block of all life. A thorough grasp of an organisms and tissues that cells make up is made possible by concentrating on the cell.

Many salad dressings contain a combination of olive oil and some sort of vinegar. You usually have to shake or mix these salad dressings well because the olive oil separates from the vinegar. Since the vinegar won't mix with the olive oil, what can you conclude about VINEGAR?
Due to difference in their density and polarity, vinegar and olive oil do not mix with each other. Thus, oil is hydrophobic whereas vinegar is hydrophilic.
What is vinegar?Vinegar is commonly known as acetic acid (CH3COOH). Vinegar contains around 6 to 8% of acetic acid in water. It is hydrophilic i.e. polar in nature. Vinegar is commercially manufactured by the technique called fermentation.
Vinegar is widely used in industries as well as it has domestic uses. It is commercially used as flavouring agent in the preparations of many food items. It is widely used as a food preservative. It is also used in certain beverages, nutritional drinks and in salad dressings.

Answer:
The independent variable in an experiment is the variable whose value the scientist systematically changes in order to see what effect the changes have.
Explanation:
Biological fluids regulate ph values using __________. This is achieved by accepting _________ when ph is low and donating _________ when ph is high.
Biological fluids regulate pH values using buffers. This is achieved by accepting H⁺ ions when pH is low and donating H⁺ ions when pH is high.
pH is the potential of hydrogen, that gives an idea about the acidity of basicity of a solution. pH can have values ranging from 0 to 14. A pH value of 7 is neutral. Values below 7 are acidic and values above 7 are basic.
Buffers are the solutions that have the ability to resist any change in pH when any acidic or basic component is added to them. A buffer solution consists of a weak acid and its conjugate base or vice versa. The human body consists of natural buffer, which is blood.

You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. Endoplasmic reticulum (ER) is the place where this observation will begin.
As all enzymes are proteins hence we will begin with the endoplasmic reticulum to study the whole process from the formation of enzymes. The endoplasmic reticulum is the site that plays a central role in the synthesis of a protein.
Ribosomes, the sites where proteins are formed after the translation of mRNA, are present on the membranes of the rough endoplasmic reticulum (RER). After the synthesis of a protein, the rough endoplasmic reticulum (RER) also transports the proteins to the Golgi apparatus where the protein is packaged and processed.

Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. Which level of protein structure most directly leads to this binding specificity?.
Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. The tertiary structure of protein leads to this binding specificity.
The tertiary structure of proteins helps in building complex three-dimensional structures proteins. This three-dimensional structure allows proteins to represent their functional groups on the outer side which can then easily interact with other molecules such as glucose.
The specificity of the proteins is maintained by the three-dimensional structure that it gets as a result of the tertiary structure.
The specific three-dimensional structure of enzymes where specific molecules can fit is referred to as the active site of the enzyme. Due to this specificity, only the right molecules can fit into the active site.

Homeowners have the option of building porches, decks, and fencing with composite boards or traditional wood boards. Traditional wood decking is made from pressure-treated lumber that resists rot, mold, and insects. The process of pressure treating wood also involves soaking the boards in a protective chemical solution. The wood boards still have to be sealed against moisture on a routine basis. Composite boards are made by pressing together ground wood scraps and recycled plastic, which is heated and pressure-treated and then coated with UV and stain-resistant coatings. Composite boards do not need to be sealed against moisture.

A hormone uses a cell signaling pathway to induce a response from a cell and help in the proper functioning of the cell. It depends on the receptors of the hormone in different cells that decide which signaling pathway will be taken by a hormone.
A hormone will have two opposing actions in two different cell types based on the receptors present for that hormone on these cells.
