Which is located inside the lung?
O the larynx
O the pharynx
O the trachea
O the alveoli
1 answer choice
Answer:
d is the answer
Explanation:
there you go have a good day
Within the lung are the alveoli. The larynx, sometimes known as the voice box, contains your vocal chords. The inhaling & exhalation of air supplied results in voice sounds.
What are the lungs used for?Respiration, a process of gas exchange, is the major purpose of the lungs (or breathing). In the process of respiration, dioxide, a waste material of metabolism, exits the blood and oxygen from the incoming air enters. Decreased lung function refers to the lungs' diminished mental capacity to transfer gases.
Do your lungs ever ache?Since the lungs lack pain receptors, it's not the lungs itself that hurt when someone suffers painful respiration. But illnesses that impact the heart, kidneys, joints, and muscles

Students in a science class were asked to investigate how missing or damaged organelles affect cellular homeostasis for cells found in muscle tissues. Which of the following questions should they ask to determine if these muscle cells are functioning properly? A. At what rate does the cell wall need to break down its carbohydrate structure to meet the high energy needs of the cell? B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? C. At what rate do the ribosomes of the cell need to work to produce enough glucose to meet the high energy needs of the cell? D. At what rate do the chloroplasts of the cell need to capture enough sunlight to meet the high energy needs of the cell?
Answer:
B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?
Explanation:
Asking scientific questions is the bedrock of scientific investigations. In this case, investigation on how missing or damaged organelles affect cellular homeostasis for cells found in muscle tissues is being carried out. Hence, an appropriate question will be that which suits organelles found in muscle cells.
Mitochondrion is an organelle responsible for the synthesis of usable energy in form of ATP in eukaryotic living cells like animal muscle cells. It is therefore an organelle found in muscle cells. An appropriate question will, therefore, be: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?
Note that other options are wrong because, cell wall and chloroplast are not found in muscle cells, while ribosomes are not organelles for production of glucose.
The apple maggot is a pest of hawthorn plants and apple trees. Before the introduction of apple trees 200 years ago, apple maggot flies laid their eggs only on hawthorns. After the introduction of apple trees, these flies started to lay eggs in apples or hawthorns. These flies tend to live and reproduce in the type of plants they were born in. Therefore, hawthorn flies tend to mate with other hawthorn flies and apple flies tend to mate with other apple flies. Some genetic differences are currently found between these two groups of flies. If these flies become different species in the future, this will be an example of what

Which of the following experimental treatments would NOT be a potentially effective strategy to inhibit or prevent cell-cell adhesion? Which of the following experimental treatments would NOT be a potentially effective strategy to inhibit or prevent cell-cell adhesion? removal of calcium ions from the extracellular space application of a protease that specifically destroys CAMs application of an antibody that inhibits the function of lectins adding an antagonist to prevent integrin function
Answer:
adding an antagonist to prevent integrin function
Explanation:
An antagonist is a drug capable of binding to a specific receptor, thus blocking the binding of endogenous ligand molecules. According to their mode of functioning, the antagonists are classified into four classes: chemical, physiological, competitive and non-competitive. Integrins are specific transmembrane receptors that facilitate cell adhesion. In consequence, in the case above indicated, the use of an antagonist for the integrin receptor will prevent cell adhesion.
In a plant in which fuzzy leaves (f) are dominant over smooth leaves (), which of the following crosses will produce only offspring with smooth leaves.
a. ff x ff
b. ft x ff
c. ft * ft
d. FF * FF
Answer:
a
Explanation:
ff x ff is the cross that will produce only offspring with smooth leaves.
What is cross?Cross means breeding of parents to produce offspring.
What is produce?Produce means to generate.
What is offspring?Offspring is the product of a cross.
f is the recessive allele of smooth leaves whereas F is the dominant allele of fuzzy leaves.
So the cross ff will give all smooth leaves where as FF will give all fuzzy leaves.

7. In what other places, besides central Africa, can people with a high eumelanin content be found
living today?
Answer:
Although people living in low latitudes have high levels of eumelanin, this pigment can be found in people around the world (because it is predominant in people with brunette hair)
Explanation:
In animals and humans, melanin pigments play key roles in eye, hair, and skin coloration. Basically, there are three main types of melanin pigments: eumelanin (brown-black and insoluble), pheomelanin (yellow-red and soluble in alkali solution) and neuromelanin (found in some parts of the brain). Eumelanin is predominant in black people and brunette hair people, this being consequently found around the world. There are two distinct classes of eumelanin: black eumelanin and brown eumelanin, which differ in their patterns of polymeric bonds, and they have an incidence on the type of coloration (e.g., black eumelanin is found in people with grey hair).
During a recent trip to Northern Europe you find 3 geographically isolated white-flowered strains, called A, B and C, of a rare species of wild rose, C. godshalkae, that usually produces red flowers. You suspect that these strains each arose independently. To gain insight into the origins of the white color, you collect individuals from the different locations and cross them. You show that the mutation that produces white flowers is recessive in each case. A. Your cross of strain A X strain B produces offspring with red flowers. How do you explain this result

Explanation:
The scientist eventually observes the cells undergo a sudden and radical shift in their structure/shape and their motility (ability to move). He asks himself questions about what is causing this shift in behaviors and begins to design an experiment to determine the answer. Briefly describe how the scientist practiced both the exploration and testing aspects of scientific inquiry
Answer:
The scientist raises a question about cellular phenomena that is tested by a hypothesis-led procedure, and the resulting information may then be used to find the reasons for his observations
Explanation:
The scientific method is a rigorous process that involves a series of steps: 1-to make observations about the real world, 2-to ask a question related to these specific observations, 3-to raise a working hypothesis, 4- to test the hypothesis, 5-to analyze the results and 6-to obtain conclusions (i.e., reject or confirm the hypothesis). In the scientific method, a scientific question must be measurable, defined and testable. Moreover, the scientific hypothesis must be a well-defined and coherent conjecture which is tested by experimental or observational procedures in order to seek answers to the scientific question.

Answer:
Hey There!!
You can say that...
Oxygen was added to early earth’s atmosphere through PHOTOSYNTHESIS!
Explanation:
The introduction of organisms which respired with the Sunlight and CO2 through PHOTOSYNTHESIS had brought a change in the Earth's early atmosphere...
PHOTOSYNTHESIS produces OXYGEN as a waste product (it's not needed by the organism)
This Oxygen is then released into the atmosphere where it was either converted into OZONE or left to move around the rest of he atmosphere...
