how might toxicology be important to other biomedical professions outside of forensics?
Answer: See explanation
Explanation:
Toxicology is a field in science that has to do with the effects of poisons, toxics and how they can be treated. Through toxicology, one can understand how harms are caused by chemicals and the health of the public can be protected.
Toxicologists study chemicals, drugs and other substances, and looks at how safe they're and their impact on living organisms. Toxicologists help in the development of methods that'll be used to know the harmful effects and the the dosages which causes it.
Furthermore, toxicology gives vital information and knowledge which the decision makers or regulatory agencies
in other biomedical fields can use in order to put programs in place that can be used to limit the exposures of humans to the substances.
In conclusion, less exposure to these substances is vital so that diseases can be prevented.
Toxicology is also used in the field of environmental health.
Toxicology will be important to other biomedical professions outside of forensics. Toxicology can be used in environmental health field which provides critical information and knowledge about the toxic substances that can be used by regulatory agencies to limit our exposures to toxic substances so we can say that toxicology plays an important role for other biomedical professions.

What happens if there is no oxygen in cellular respiration of glucose?
You are cleaning your room, when all of a sudden the smoke alarm goes off. You go into the kitchen and it is very smoky, so you inhale smoke. Your body has to immediately get rid of the carbon molecules you just inhaled. Explain all the parts of the cell involved in getting the smoke out of your cells.
Answer: The smoke goes to the cells of the mouth or buccal cavity, nasal cavity, trachea, larynx, and then finally distributed into the bronchi (small tubes) in the lungs.
Explanation:
Respiratory system can be defined as the complex system of organs that allow us to obtain oxygen for biochemical oxidation of food and releasing energy in the form of ATP. The breathing is a process in which the air is inhaled inside the respiratory system and oxygen is absorbed by the cells and carbon dioxide is expelled out of the body. The pathway of oxygen is cells of the mouth or buccal cavity, nasal cavity, trachea, larynx, and then finally, distributed into the bronchi (small tubes) in the lungs and it is reverse for carbon dioxide or carbon monoxide gas components present in the smoke. The red blood cells are the cells that are involved in getting rid of smoke out of the body, as they have hemoglobin which has binding efficiency with both oxygen and carbon dioxide. The exchange of deoxygenated blood (carbon dioxide containing blood) takes place in the blood capillaries. From the blood capillaries the carbon dioxide is expelled out from the bronchi following the entire route of expiration.

The phenotype of an organism ?
- represents its genetic composition.
- occurs only in dominant pure organisms.
- cannot be seen.
- reflects all the traits that are actually expressed
HELP PLEASE
Answer:
The phenotype of an organism reflects all the traits that are actually expressed.
Explanation:
Phenotype refers to the visible or evidentiable characteristics that depend on the genotype, which is stored in the DNA. Phenotypic expression, mainly determined by genes, also depends on the influence of the environment on the individual.
Although the phenotype expresses characteristics such as skin, eye and hair color, height or shape of the nose, some characteristics are not entirely visible, such as specific functions or synthesized proteins.
The other options are not correct because:
Represents its genetic composition: this is genotype. Phenotype occurs in all individuals, both dominant and recessive.Many phenotypical characteristics are visible.I need help with this one anyone?

10. Vestigial structures
Are dangerous and should be removed.
Are fully functional structures in a species.
Are usually present, but are no longer functional.
Have been completely eliminated from the species.
Answer:
Are usually present, but are no longer functional.
Explanation:
Vestigial structures are "evolutionary remnants". They are anatomical features that were once important throughout the organism's evolution, but now have no function. However, they aren't harmful either, so there has been no selective pressure for them to be removed via evolution.
Good examples in humans are the tail bone, wisdom teeth, and the appendix.
What is a buffer? Why is it useful to cells?
Buffer are defined as substances that maintain a constant range of pH by the addition of the base and acid. It is important for cells to maintain the osmotic pressure and pH in the cell environment.
What is the importance of a buffer?In biology, the buffer has been the substances that are organic in nature and are used for regulating and controlling the level of the acids and bases that alters the pH of the system. It plays a crucial role in cells.
It is important for the cell to have a buffer solution, like bicarbonate ions in the blood that maintains the pH and the concentration of the hydrogen and hydroxide ions. It provides regulation of the osmotic balance and maintains the internal environment condition of the cell.
Therefore, the buffer is important for cells.

The level of organization is best represented by the liver is tissue. The correct option is a.
What is a tissue?In biology, tissue is described as a collection of cells that share a common structure and serve a single purpose. French is where the word "tissue," which means "to weave," comes from.
Tissue is a collection of cells with a common structure and function that work as a single unit. The body's tissues give it shape and aid in energy storage and heat retention. Connective tissue, epithelial tissue, muscle tissue, and nervous tissue are the four different types of tissues.
The hierarchy of intricate biological systems and structures that, in a reductionistic manner, define life is known as biological organization. The conventional hierarchy goes from atoms to biospheres, as shown in the details below.
Therefore, the correct option is a. tissue.

II. Genetic information is passed from a parent cell to a daughter cell.
III. The basic units of all living things are organelles.
Answer:
the statement that is correct is the lll.
The statement which is supported by the principles of cell theory is as follows:
Genetic information is passed from a parent cell to a daughter cell.Thus, the correct option for this question is B.
What is Cell theory?Cell theory was proposed by two famous scientists known as M.J. Schleiden and T. Schwann. The principles of cell theory are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.A Cell is the structural and functional unit of organisms.This cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from a pre-existing cell. A Virus is an exception to the cell theory.
Originally, none of the given statements exactly matches any one of the three principles of cell theory. But the second option reached approximately near around it.

A force of 240 N causes an object to accelerate at 3.2 m/s2. What is the mass of the object?
A.75N
B.75 kg
C.0.013 kg
D.768 kg
Which is the answer?
Answer:
B.75 kg
Explanation:
Given parameters:
Force on the object = 240N
Acceleration of the object = 3.2m/s²
Unknown:
Mass of the object = ?
Solution:
Force is the pull or push on an object. According to Newton's first law; it is mathematically expressed as;
Force = mass x acceleration
The unknown here is the mass, simply input the parameters and solve for it;
240 = mass x 3.2
mass = [tex]\frac{240}{3.2}[/tex] = 75kg
The mass of the object is 75kg
