Answer:
Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Explanation:
Mark as Brainliest Answer
Air travels through the following structures on its path to the alveoli (the site of gas exchange): nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles.
What is breathing?The trachea (windpipe), which is further separated into bronchial tubes, receives it from there. Bronchioles are another division of the bronchial tube, the little alveoli structure is where the bronchioles eventually come to a stop.
Through our noses, we breathe air into our bodies, after then, it moves via the larynx, pharynx, and nasal cavity before entering the windpipe, also known as the trachea.
Therefore, air enters both lungs through bronchi that branch off of the trachea.

This is false. They alter their generations by giving birth to newborn plants. they do not alter their generations by switching between phases.
Explanation:
A phase change diagram for water is shown below. The star on the diagram represents the temperature and pressure of some water vapor that a scientist has placed in a special container.
The scientist wants to make changes to the container that will allow the container to have some liquid water, some ice, and some water vapor at the same time. What change should the scientist make to the container?
A.
The temperature should not be changed, but the pressure should be increased.
B.
The temperature should not be changed, but the pressure should be decreased.
C.
The temperature should be increased, but the pressure should not be changed.
D.
The temperature should be decreased, but the pressure should not be changed.
Answers
The temperature should be decreased, but the pressure should not be changed.
What is Temperature and Pressure relation ?In contrast, as a gas's pressure falls, its volume rises as a result of the gas's ability to spread its particles farther apart. Because the volume of the gas has risen, weather balloons become larger as they ascend through the sky to lower pressure areas.
This is because when the atmospheric gas exerts less pressure on the balloon's surface, the inside gas expands until the internal and external pressures are equal.
Some of the early studies that established the quantitative relationship between the pressure and volume of a gas were done by the Irish chemist Robert Boyle (1627-1691).
Therefore, The temperature should be decreased, but the pressure should not be changed.

Mendel carried out a dihybrid cross to examine the inheritance of the characteristics for seed color and seed shape. The dominant allele for yellow seed color is Y, and the recessive allele for green color is y. The dominant allele for round seeds is R, and the recessive allele for a wrinkled shape is r. The two plants that were crossed were F1 dihybrids RrYy. Identify the ratios of traits that Mendel observed in the F2 generation. Create a Punnett square to help you answer the question.
Answers
Simply create a dihybrid cross, and then create ratios from the outcomes. Remember that ratios only come from the bottom part of any fractions *If you need more help on dihybrid crosses I can send an example image
Dihybrid cross is a experiment including mating between two organisms, that are identically hybrid for two traits. The ratios of traits in F2 generation will be 9:3:3:1.
What is Punnett square?Punnett square is the square diagram used to identify the genotype of the cross in experiment.
Genotype is the collection of genes and phenotype is the physical appearance of the individual. The Punnette square for the given case will be creates as given in the image attached.
Thus, the ratio of traits will be 9:3:3:1 in the F2 generation.
