What conditions is it appropriate to re-contact the individuals who provided biological specimens?
Original signed consent documents include provisions for recontacting subjects it is appropriate to re-contact the individuals who provided biological specimens.
A biological specimen, also known as a biospecimen, is a laboratory specimen used in biology that is kept by a biorepository for research. A sample of such a specimen would be taken from the specimen's source in order to make it representative of all other samples taken from the same source. For research purposes, it is preferable for biological specimens to be preserved so that they maintain their comparability to newly-collected specimens.
Blood, urine, saliva, and a variety of other biological specimens (or biospecimens) are taken from patients as part of routine patient monitoring and care as well as for use in basic, clinical, and epidemiologic research investigations.

A strategy for fighting bacterial infections uses viruses. Viruses that infect bacteria are called bacteriophages. Phage comes from the Greek word for “eater.” Explain why it is not accurate to call a virus that kills bacteria a “bacteria eater." What happens when a virus attacks a cell?
It is not accurate to call a virus that kills bacteria a "bacteria eater" as it does not technically eat bacteria but infects it. The virus that enters a cell replicates it's genome inside it causing the cell to be infected with it.
Bacteriophages, or simply phages, are viruses that infect and kill bacteria. Bacteriophage is a name that means "bacteria eater." Although theoretically speaking, viruses don't consume anything, they do kill the bacteria and other infected cells. They have been demonstrated to successfully combat and eradicate multi-drug resistant bacteria and are the most prevalent biological organisms in nature.
Virus particles infiltrate host cells. Once a viral particle penetrates a host cell, its nucleic acid component or it's genome disrupts the processes of the cell, essentially taking over the host cell's proteins and other components to produce new viral particles.

name the monomer and describe the importance of the order of these monomers and how dna is related to this order
Nucleotides are the monomers of DNA. They consist of five-carbon sugar deoxyribose, a phosphate group and a nitrogenous base attached to the sugar. Nucleotides including adenine A thymine T guanine G and cytosine C are available.
DNA monomers or nucleotides can bind phosphates and sugars on the outside and nitrogenous bases on the inside where they can bind to other nitrogenous bases to form a ladder. DNA is a polymer. The monomeric units of DNA are nucleotides and the polymers are known as polynucleotides.
Monomers are small mostly organic molecules that can combine with other similar molecules to form very large molecules or polymers. All monomers have the ability to form chemical bonds with at least two other monomer molecules. The unique structure of DNA allows the molecule to replicate itself during cell division. When a cell prepares to divide, the DNA helix splits in the middle and becomes two single strands.

which organism has a nerve net that allows it to a stimulus in a coordinated way
The organism that has a nerve net that allows it to a stimulus in a coordinated way is called option C: Hydra.
What kind of animal is Hydra?The majority of cnidarians, including those in the genus Hydra, contain what is known as a neural net, which is an organism-wide network of distinct and individual nerve cells and fibers.
Hydra species have two nets, one attached to the gastrodermis and the other situated between the epidermis and the muscles.
Invertebrate freshwater animals of the genus Hydra belong to the class Hydrozoa. Such an organism has a thin, transparent tube for a body that can grow up to 30 millimeters long but can also contract significantly.
Therefore Hydra have nerve net that is used respond to the touch of physical contact as well as other functions.

layers of sand and other sediments that become sedimentary rock can contain
The particles which forms sedimentary rocks usually contains calcite or quartz.
Understanding the composition of sedimentary rocks.The composition of a substance are what the substance is made up of. Within the context of this question, before the sedimentary rocks are formed, the layers of the its constituents which when subjected to high temperature and forms sedimentary rock contains a substance known as quartz. This quartz is also known as the siliciclastic rocks.
However, the layers or substance or particles which forms sedimentary rocks also contains the carbonate rocks also known as calcite.
There are three major types of rocks:
Igneous rock: It is formed by the cooling of molten rock, either below the surface (intrusive) or on the surface (extrusive).Metamorphic rock: It consists of pre-existing rock mass in which new minerals are formed at higher temperatures and greater pressures.Sedimentary rocks: It is formed by the deposition of either the weathered remains of other rocks, the results of biological activity, or precipitation from solution.So therefore, the constituents which makes up sedimentary rocks contains calcite and quartz.

If a hypothesis that you test is not supported by the result of your experiment was your investigation there for a future explain
It signifies that, to a best of knowledge, the hypothesis is false since there is a lack of adequate objective facts to support it.
Hypothesis- Professionals frequently express hypotheses in if/then statements, e.g., if someone consumes a lot more sweets, then they will have cavities through their teeth. These claims list particular factors and make predictions about the outcomes. In this instance, the sugar content is the variable, and cavities are the outcome.

True or false when the particles are compressed they are closer together and they bump into eachother more often
The particles are compressed, closer together, and collide more frequently, energy is transferred during collisions.
Are there collisions between particles?Because of the tighter spacing between particles, particles move quickly in all directions but collide more frequently than in gases. Because the particles gain kinetic energy as the temperature rises, they move faster, increasing the likelihood of collisions and diffusion.
What occurs when a solid's particles are crammed so closely together?A solid is made up of very closely spaced-apart particles. Each particle is firmly anchored in situ and is limited to stationary vibration. Many solids contain particles that arrange themselves into crystals in a predictable, repeating pattern.
Why do molecules collide with one another?The molecules will travel quicker and are more likely to collide with one another if there is more energy available to them. Higher temperatures should result in more molecule-to-molecule collisions and more frequent chemical reactions.

For the following please tell me if they can or cannot cross the cell membrane without help? Why or why not.
Na+, Glucose, O2, Insulin, CO2, Fructose, K+,
Na+, K+, and insulin cannot cross the cell membrane without help whereas Glucose, oxygen, carbon dioxide and Fructose can diffuse.
What type of molecules can cross cell membranes without energy?Small nonpolar molecules like oxygen and carbondioxide are soluble in the lipid bilayer and so they can easily cross cell membranes. Small molecules such as water can also diffuse through cell membranes but larger molecules such as glucose, cannot diffuse through the cell membranes. Nonpolar molecules can pass through the cell membrane easily. Some larger nonpolar molecules like steroid hormones can also pass through the cell membrane easily. Moving through the cell membrane without the need for assisting proteins is called passive diffusion.
So we can conclude that Glucose, oxygen, carbondioxide and Fructose can cross the cell membrane without energy.
