What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli

Answers

Answer 1

Answer:

D. Alveoli

Explanation:

Functionally, the respiratory system is separated into a conducting zone and respiratory zone:

Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.

Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).

The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.

Answer 2

Answer:

Yep, the correct answer is D.) Alveoli

Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.

Answers

Answer:

B

Explanation:

the longest phase in the cell division is interphase because the DNA replication occurs in this phase

As per the image interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. The correct option is D.

What is cell cycle?

The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells.

A cell cycle is the series of events that takes place in a cell as it grows as well as divides.

A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.

Interphase is the longest stage, according to the image, since the maximum of the cells in the photo have uncondensed chromatin as well as are not dividing.

Thus, the correct option is D.

How does light behave around opaque, transparent and translucent
Need answer ASAP please
NO copy and paste thanks!

Answers

Answer:

Transparent objects allow all the light to pass through them. Opaque ones allow no light to pass through. Translucent allows light to go through but the area in it is no visible to determine the object

Explanation:

Think of Transparent as a window u can see straight through it is clear.Think of Translucent as a window with cold fog on the window light can come through it but you can't see whats outside.Think of Opaque as a black chalkboard light reflect on it but light cannot go through it

Answer:

Transparent: light will completely pass through and is very visible through the transparent object. For example, sunlight through a window

Translucent: some light will pass through, will be somewhat visible. For example, if you put a flashlight or your phones flash against a piece of paper, the light will pass through but not as much as light through a window

Opaque: you will not be able to see light through an opaque object, for example, putting a flashlight against a large book or a rock. No light will pass through the object.

Assume that producers in an ecosystem have 1,000,000 kilocalories of energy. How much energy is available to primary
consumers?
5. Which trophic level has the greatest biomass?

Answers

Assuming that producers in an ecosystem have 1,000,000 kilocalories of energy, 100,000 Kilocalories of energy would be available to primary consumers.Producers is the trophic level with the greatest biomass

HOW IS ENERGY TRANSFERRED:In a food chain, energy is being transferred when one organism in a particular trophic level feeds on another organism in a lower trophic level.

The lowest trophic level contains the producers, which are organisms that start the food chain. However, only about 10% of energy is available to the organism in the next trophic level as 90% is lost as heat.

Therefore, according to this question, if it is assumed that that producers in an ecosystem have 1,000,000 kilocalories of energy; 10/100 × 1,000,000 = 100,000 kilocalories of energy will be available to primary consumers.

WHAT IS BIOMASS:The total biomass of an organism in each trophic level decreases going up. This is due to the lesser energy transferred from one trophic level to the next.

As the trophic level increases, lower energy is available to convert into biomass. Hence, the higher the trophic level, the lower the biomass.

Therefore, if this is the case, the producers at the first trophic level will contain the greatest biomass which will decrease as the food chain progresses upwards.

What percent of the offspring will be red, if we cross two pink tulips?




75 %

Answers

Answer: 50

Explanation:you are combining two pink to the possibility of the tulips being red will be 50 50

It is a case of incomplete dominance. 25% of the offspring will be red. Therefore, option C is correct.

What is incomplete dominance?

When two heterozygous alleles in a gene interact with each other, their traits are expressed partially, because they both are not dominant on each other. This type of dominance is called incomplete dominance.

It is not necessary to do a test to identify the heterozygous in incomplete dominance. The phenotype and genotype ratio is the same in this dominance. Incomplete dominance is different from co-dominance.

When two heterozygous pink tulips (Rr) cross, then 25% red (RR), 50% pink (Rr), and 25% white (rr) tulip flowers are produced. The phenotype and genotype ratio will be 1:2:1. Therefore, option C is correct.

In fruit flies, the gene for eye color is located on the X chromosome, and the red eye allele (R) is dominant
to the white eye allele (r). A carrier female is mated with a male fly with genotype X
rY. Which of the
following statements best describes the expected outcome of the cross?
a. The chance of an offspring having red eyes is 75%
b. The chance of an offspring having white eyes is 50%
c. The chance that a male offspring will have white eyes is 0%
d. The chance that a female offspring will have red eyes is 100%

Answers

Answer:

b. The chance of an offspring having white eyes is 50%

Explanation:

So the genotype of the male fly is X^r Y. This means the male has white eyes because he only has one X chromosome, so he will express whatever allele is on that chromosome.

The genotype of the female fly, though, is X^R X^r. This is because carriers are heterozygous for traits, and the sex chromosomes of most females is XX (with some exceptions, like XXX, or X (Turner syndrome)).

If we cross this, what are the outcomes? Do a Punnett square. You get the genotypes of X^r X^R, X^r X^r, X^R Y, and X^r Y. The expected phenotypes are a red eye female, white eye female, red eye male, and white eye male.

Now, let's look at the choices:

A.: The chance of an offspring having red eyes is not 75%; it is 50%.

B.: The chance of an offspring having white eyes is 50%!!!

C.: The chance that a male offspring will have white eyes is 50%, not 0%.

D.: The chance that a male offspring will have white eyes is 50%, not 100%.
