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

What trait most likely evolved in ferns that was not
present in the earlier groups?
The first groups of land plants to evolve were
liverworts, mosses, and hornworts. These plants were
small and grew close to the ground because they relied
on water being able to move on its own through the
plant bodies. The next groups of land plants to evolve
were fems, which could grow bigger and taller because
they could transport water and food.

A scientist is conducting research to see whether dogs or cats are more popular. He goes to a dog park and asks all of the owners which pet they prefer. 100% of those polled stated that dogs are their favorite animal.
This experiment is an example of:
A) personal bias
B) experimental bias
C) cultural bias
D) a controlled experiment
Answer:
C) Cultural bias
Explanation:
A cultural biased experiment is one which is based on the cultural views or perceptions. In this experiment where a scientist is trying to see whether dogs or cats are more popular, he conducted a questioning assessment from all the dog owners in a dog park.
He found that 100% (all) of them preferred dogs to cats. This preference is due to the to the culture of the dog owners who have a mentality of dogs being their best choice without exploring possibilities from other pet animals. The scientists goes to the dog park knowing that the dog owners will favour dogs over cats. Hence, it is a cultural biased experiment.

4. A woman who is heterozygous for freckles and a carrier for PKU disease marries a
man who is also heterozygous for freckles and a carrier for PKU disease. List the
probability for each of the four possible phenotypes (not genotypes) in their offspring.
Answer:
Freckles, no PKU- 9/16
Freckles, PKU- 3/16
No freckles, no PKU- 3/16
No freckles, PKU- 1/16
Explanation:
This question involve two distinct genes; one coding for possession or not of freckles and the other for PKU disease in humans. Allele for freckles (F) and no PKU (P) are dominant over the alleles for no freckles (f) and PKU (p) respectively.
N.B: Possession of freckles is a dominant trait i.e. FF and Ff possess freckles
If a woman who is heterozygous for freckles and a carrier for PKU disease (FfPp) marries a man who is also heterozygous for freckles and a carrier for PKU disease (FfPp), they produce the following gametes: FP, Fp, fP, and fp
Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
Freckles, no PKU (F_P_) - 9/16
Freckles, PKU (F_pp) - 3/16
No freckles, no PKU (ffP_) - 3/16
No freckles, PKU (ffpp) - 1/16
The possible phenotypes of the offspring with their probabilities are:
Freckles and PKU = 3/4 x 1/4 = 3/16Freckles and no PKU = 3/4 x 3/4 = 9/16No freckles and PKU = 1/4 x 1/4 = 1/16No freckles and no PKU = 1/4 x 3/4 = 3/16Each of the traits would be independently inherited:
Freckles are autosomal dominant traits. Assuming the allele for freckles is A, a heterozygous individual will have the genotype Aa.
Aa x Aa
AA Aa Aa aa
Probability of having freckles = 3/4
Probability of not having freckles = 1/4
PKU is an autosomal recessive trait. Assuming the allele to be b, heterozygous individuals will have the genotype Bb.
Bb x Bb
BB Bb Bb bb
Probability of having PKU = 1/4
Probability of not having PKU = 3/4
The four possible phenotypes with their probabilities are:
Freckles and PKU = 3/4 x 1/4 = 3/16Freckles and no PKU = 3/4 x 3/4 = 9/16No freckles and PKU = 1/4 x 1/4 = 1/16No freckles and no PKU = 1/4 x 3/4 = 3/16More on dihybrid crosses can be found here: https://brainly.com/question/1185199?

Cytokinesis is the process of division of cytoplasm. The correct answer is cytokinesis.
The primary method of reproduction for unicellular organisms, cytokinesis also occurs during the growth and repair of tissues in higher plants and animals, as well as during the development of the embryo. Whether in mitosis or meiosis, it typically happens after nuclear doubling. Prokaryotes primarily reproduce by binary fission, in which the mother cell grows until it physically splits into two identical daughter cells through a process called cytokinesis.
Actin and myosin, the proteins involved in muscle contraction and other types of cell movement, form a ring around the cell to constrict it, causing cytokinesis to occur in animal cells. The formation of a new cell wall, known as the cell plate, between the two daughter cells divides the cytoplasm in plant cells. Following the division of the daughter cells, cellulose synthesis starts, and the cell plate develops into the primary cell wall.
Therefore, in any cell the cytoplasm, divides by cytokinesis. The correct answer is option c i.e. cytokinesis.

Why is it important for the eukaryotic cells to have membrane-bound organelles? *
Answer:
Together, the total area of a cell's internal membranes far exceeds that of its plasma membrane. Like the plasma membrane, organelle membranes function to keep the inside "in" and the outside "out." This partitioning permits different kinds of biochemical reactions to take place in different organelles.

100 POINTS!!! ANSWER ASAP [WRITE 5 SENTENCE ANSWER] If 2 objects have the same volume, but 1 has more mass than the other, explain if the densities of the 2 objects are the same or different. Why?
Answer:
Density is determined by an object's mass and volume. If two
objects take up the same volume, but have one has more mass, then it
also has a higher density. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.

A medicine to remove the redness in eyes was tested in a group of 100 students. Each student took either the medicine or a placebo in both eyes. The participants were given some free time after receiving their drops. The researcher did not keep track of what they did in that free time. It turns out that many of the people receiving the medicine spent their time outside and many of the people receiving the placebo spent their time inside. The results may now be biased because the variable location (inside vs. outside) is now a/an ____ variable.
Answer:
Independent variable
Explanation:
In a scientific experiment, an independent variable is that variable which the experimenter changes or manipulates in order to effect an outcome. Only one independent variable should be tested at a time in a good experiment, all other variables should be kept constant. The initial independent variable in this experiment is TYPE OF SUBSTANCE put in the students' eyes.
However, according to the question, the researcher did not keep track of what they did in that free time. Hence, many of the people receiving the medicine spent their time outside and many of the people receiving the placebo spent their time inside. The location of every student should be a CONSTANT VARIABLE i.e. same for all students but now it has become an INDEPENDENT VARIABLE because it has been changed.

How can a scientist test a hypothesis if it is not possible to do a controlled experiment.
Answer:
In an experiment, the researcher needs to have a control group with an experimental group where both groups are identical in every way except that the controlled group does not gets the experimental treatment.
Sometimes, it is not possible to do a test or the experiment utilizing a controlled trial (due to ethical reasons or no practical method available). All things considered, a researcher may test a theory by making predictions about outcomes or patterns that ought to be found in nature if the hypothesis is right.

In this activity, you will research the genetic diversity in two fish variants. The Mexican tetra (Astyanax mexicanus) has two notable variations: the surface variety and the blind cave fish variety. In this activity, you’ll use credible websites to find the following information about these two fish:
What type of habitat does each fish live in?
How do their physical characteristics differ?
How are they similar?
Can the two types mate with each other?
Why are their characteristics advantageous to their environments?
When you’ve found the information, answer the following questions.
Part A :
What are the similarities and differences between the two fish varieties?
Part B:
Do you think these fish are an example of natural selection among two populations of the same species? Explain your answer.
Part C:
Explain how the characteristics of the two types of fish relate to the genetic diversity of the species.
Answer:
Part A-One of the variations have eyes as well as some pigmentation on them. They live near the surface of the water. The other variation does not have eyes and are often albinos. I found that these fish live in deep, dark caves.
Part B-Yes. I think that these fish are an example of natural selection. The blind fish live in caves and eyes take up energy that could be used somewhere else in the fish. So, they developed into fish with no eyes, allowing them to function more efficiently.
Part C- As a species, they have genetic diversity because the two populations have separate genes. The two fish types developed different traits because of their separate habitats.
