What is cell?"A cell is defined as the smallest, basic unit of life that is responsible for all of life's processes.” Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life
What defines an organ system?An organ system is defined as a group of organs that work together to perform bodily functions. For example, the organs in the gastrointestinal (GI) system each play a unique, important role in food digestion.

5(x + 6) - 2x = 3(x + 10)
Answer:
5(x + 6) - 2x = 3(x + 10)
or 5x + 30 -2x = 3x + 30
0r 0=0
Explanation:
Answer:
x=0
Explanation:
5x+30-2x=3x+30
combine like terms subtract 3x from both sides and 30 from both sides
5x-2x-3x=30-30
-6x=0
divide both sides by -6
x=0

Explain in your own words an atom and an element.
Answer:
Explain in your own words an atom and an element.
Explanation:
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

How is DNA expression regulated in individual cells?
Answer:
Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription (when the information in a gene's DNA is transferred to mRNA). Signals from the environment or from other cells activate proteins called transcription factors.
Explanation:
Gene regulation can take place at any stage of gene expression, although it often happens during transcription when the data from a gene's DNA is converted to mRNA.
What is gene regulation?Proteins known as transcription factors are activated by signals from the environment or from other cells.
Limiting the amount of mRNA that is generated from a certain gene regulates transcription.
Eukaryotic gene expression is regulated by the nucleus-based mechanisms of transcription and RNA processing and the cytoplasm-based activities of protein translation.
Therefore, the translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.

Which of the following does NOT describe a protein function? A. Enzyme B. Short-term energy C. Antibody D. Endorphin
Answer:
B. Short-term energy
Explanation:
A, C, and D are all protein functions.
B is characteristic of carbohydrates.
Proteins are the macromolecules that act as enzymes, antibodies, and endorphins. It does not act as short-term energy. Thus, option B has been correct.
What are proteins?Proteins are polymers that are large molecules and are essential for several bodily activities, including immune reactions, hormone synthesis, growth, development, energy, and enzyme activities.
Enzymes are made of proteins that speed the biochemical reactions, antibodies are made of proteins that are immunoglobulins and act as a defense for the body. Endorphins are the hormones that are synthesized in stress and painful conditions.
Proteins just do not provide short-term energy but provide energy that can suffice for a longer period of time so that it can perform the various functions and activities in the cell.
Therefore, option B. proteins are not short-term energy.

(b) Describe how a student could test cow's milk to show whether it contains protein
different types of carbohydrate.
To show that cow milk contains protein and different types of carbohydrate,food tests should be carried out by the student.
Carbohydrates (sugars) are the main sources of food through which the body derives energy from.
The various types of carbohydrate are the simple sugars, complex sugars and starch.
Proteins are the main body-building substances which are necessary for the maintenance of health.
The cow milk contains proteins and a type of carbohydrate called lactose which is an example of complex sugar.
To test for protein in milk, xanthoproteic reaction test should be carried out by the student. The procedure includes:
To the milk solution add a few drops of concentrated nitric acidA white precipitate forms, which turns yellow on heating.Cool the contents and add a few drops of ammonia solution.The colour of the precipitate deepens to yellow indicating presence of protein in the cow milk.To test for carbohydrate in milk, a test for complex sugar should be carried out by the student. The procedure includes:
Add milk solution and hydrochloric acid into a test tube. Place the test tube inside a boiling water-bath.The acid hydrolyses the complex sugar to simple sugars.Fehling's test is then carried out on the simple sugars that are formed which are glucose and galactose.An orange-red precipitate indicates a positive result.Learn more here:

When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity? a) the ions in the solution interact with the sugar and that interferes with its solubility b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water
Answer:
The correct answer is option c.he solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
Explanation:
The Solution contains a solute (sucrose for this situation) and dissolvable (water for this situation). A saturation or unsaturation of a solution relying upon whether it can even now dissolve a solute or not.
As indicated by this inquiry, the sucrose solution is saturated as the 0.7 M sucrose arrangement doesn't disintegrate the sucrose (solute) anymore. The immersion of the sucrose arrangement happens in light of the fact that the measure of solutes is likening the number of solvents in the solution. The solubility of a particular solution relies on saturation.
