Answer:
Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections.
Why was "spontaneous generation" a theory and not a scientific law?

b. A theory is based on the most current experimental data and may change as new
technology and discoveries are made.
A theory must be tested for many years before becoming a law.
d. A theory applies to phenomenon of living things and laws apply to non-living.

Answer:
Why was the theory of spontaneous generation a hindrance to the development of the field of micrbiology? Spontaneous generation, proposed by Aristotle, was believed for 2000 years. ... Although his experiment showed no spontaneous generation it was said that his sealed vials did not allow air for organisms to thrive.

Identify this functional group
Answer:
Hydroxyl
Explanation:
Hydroxyl groups are simple structures consisting of an oxygen atom with two lone pairs bonded to a hydrogen atom.
A hydroxy or hydroxyl group is a functional group with the chemical formula -OH and composed of one oxygen atom covalently bonded to one hydrogen atom.
Using these given definitions, a hydrogen bond is labeled with one linkage, while a covalent bond is with two links to the Carbon Atom.

Associate specific relationships between science and/or technology and human population growth.
The relationship between population growth and technological change has been debated since the end of the eighteenth century a debate whose main configuration has proved remarkably persistent. During the ensuing 200 years, historically unprecedented rates of change have been observed in both variables: in industrial, commercial, and communications revolutions spreading out from Europe, North America, and Japan; in parallel (though spatially and temporally uneven) revolutions in the technological base of agricultural production; and in a demographic transition–in which mortality decreased and fertility first increased, then decreased that is still underway in many developing countries. Interconnections there must be, yet the attribution of primacy and direction of causation among these variables, not to mention the nature of the mechanisms involved and means of influencing outcomes in the interest of meeting social goals, remain controversial. Meanwhile, a new awareness of the emergence of complex social-environmental systems, whether at local or global levels, has extended the debate beyond the discipline of economics, and broadened its emphasis from the welfare of the human race to that of the planet.
How might the interdependence of organisms in a specific habitat be
helped or harmed as a result of changes in the ecosystem over time?
Changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.
What is the effect of change in ecosystem over time on the interdependence of organisms in a specific habitat?Changes that occur in an ecosystem may occur as a result of natural or man-made causes.
Changes in an ecosystem may have positive or negative effects on the interdependence of organisms in a specific habitat.
For example in an aquatic habitat where certain species of fishes like sharks depends on smaller fishes like salmon to survive, if humans were to reduce the salmon population by overfishing, the sharks will be negatively affected as they may have to migrate to new hunting grounds.
However, some other fishes that are prey to shark may be able to grow more with the reduction on shark population in that area.
Therefore, changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.

Explain why sickle cell anaemia is persistent in the tropics yet it is lethal and these areas have high malaria Providence.
Sickle cell anemia is persistent in the tropics because those with sickle cell anemia cant contract the malaria virus because of the shape of their blood cells, and this is advantageous in the tropics where there are more malaria cases. So those with sickle cell anemia live to pass on their genes.
the cell that is infected by a virus is called a bacteriophage

The left cerebral hemisphere controls the muscles on the right side of the body and vice versa. Which pathway generalization best explains this phenomenon
Given our understanding of neuroanatomy, we can confirm that the left cerebral hemisphere controls the muscles on the right side of the body and vice versa due to the motor decussate of the cortical spinal pathway.
A decussate in regards to the nervous system is described as when the nerve fibers cross from one side of the central nervous system to the other. The decussate in question corresponds to the cortical spinal motor decussate.
The cortical spinal pathway is the nerve pathway that is in charge of muscular control and therefore is the pathway that is responsible for the phenomenon described in the question.

Is phrenology an example of science or
pseudoscience? Explain your answer.
Answer:
Pseudoscience
Explanation:
Phrenology is an example of pseudoscience. It is the belief that studying the conformation of the skull reveals the character traits and mental faculties of an individual, a conclusion not at all rooted in fact but nevertheless studied and pursued as such thereby giving a false sense of being based in scientific methods.
Answer:
Pseudoscience
Explanation:
Phrenology is an example of pseudoscience because Gall held beliefs and ignored any information that didn't align with his beliefs. This is a direct example of Gall using pseudoscience and testing his hypothesis with bias through his belief.

The structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the:
Answer:auditory tube
Explanation
The structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.
What is the structure of Ear?The ear is a type of organ of hearing and balance which consists of a cavity in the skull structure lined with soft tissue. It surrounds three distinct spaces filled with air or fluid i.e. the outer, middle, and inner ear. These specialized spaces host both the sound transmission apparatus and the sensory apparatus.
Types of bones present in the ear are
1. Hammer shaped bone known as malleus which is attached to the eardrum.
2. Anvil shaped bone known as incus present in the middle of the chain of bones.
3. Stirrup shaped bone known as stapes is attached to the membrane-covered opening which connects the middle ear with the inner ear (oval window).
The cavity of the middle ear is a narrow air-filled space which is a slight constriction divides it into an upper and a lower chamber known as tympanic cavity proper below and the epitympanum above. The main function of the Eustachian tube is to equalize the air pressure between the environment and the middle ear.
Thus, the structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.

There are no PHOTORECEPTORS in the OPTIC DISC located where the nerve fibers of the RETINA leave the eye and enter the OPTIC NERVE. This region is commonly called the BLIND SPOT.
The retina is an important layer of nervous tissue that covers the inside of the eye, in which the sensation of vision initiates.
Photoreceptors are specialized cells within the retina that respond to light stimuli. In the retina, there are two types of photoreceptor cells: cones and rods.
The blind spot is a small portion of the visual field of the eye that localizes in the optic disk within the retina.

what are some drawbacks to using mice in genetic studies?
Answer:
One drawback to using transgenic, knock-in, and knock-out mice to study human diseases is that many disorders occur late in life, and when genes are altered to model such diseases, the mutations can profoundly affect development and cause early death.
hope this helps
Explanation:
Genetically altered mice have served to recapitulate human diseases, including cancer, glaucoma, heart disease, and diabetes. However, despite their genetic similarity to humans, mouse models are criticized for their failure to accurately mimic human disease phenotypes.
Why it's bad to use mice as an experiment:
The use of mice as model organisms to study human biology is predicated on the genetic and physiological similarities between the species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species.
