B
the lungs is an organ of respiration,while the trachea allows passage of air from the larynx to the bronchi Of the lungs.. the alveoli is a tiny air sac that takes the oxygen and allows the body going
The trachea divides into a left and right bronchus inside the lungs. These further separate into bronchioles, The tiniest bronchioles have tiny air sacs at their ends. They are known as alveoli. Thus, option B is correct.
What is the role of trachea and alveoli?The trachea splits into the right and left principal bronchi at the mediastinum at the level of the fifth thoracic vertebra.
The bronchi split off into progressively smaller channels before coming to an end in tiny air sacs known as alveoli.
During this process, oxygen diffuses from the alveoli to the blood through the alveolar walls' capillaries (small blood vessels).
Hemoglobin in red blood cells absorbs oxygen as it enters the bloodstream.
Therefore, trachea and alveoli in the respiratory system work together to allow gas exchange.

which part of the brain controls the reproductive system
Work backwards: if you find an offspring that is not genetically identical to its parent's organism, what type of reproduction created it? why?
Answer:
The organism was created via sexual reproduction.
Explanation:
If it were genetically identical to its parent, then that would've meant that it was created asexually. In sexual reproduction, the offspring's DNA is more or less a combination of both parents' DNA.

Explanation:
is a rotting log considered living or non living? why?
Answer:
A rotting log is nonliving. However, it can have mold, lichen, or fungus growing on it, which is not the log itself. Those three things are living. And though the log was once a living tree, at it's current state, it is nonliving.

Not all traits are determined solely by genes. Many traits have been found to exhibit phenotypic plasticity, which
occurs when individuals with the same genotype exhibit different phenotypes in different environments. Which of the
following is an exampleof phenotypic plasticity?
Well-maintained hedges can be shaped into artistic displays.
O A person who experienced malnutrition as a child is short in stature as an adult.
O Bears living in the arctic developed white fur and cold tolerance over many generations.
Certain breeds of dog have been bred for specific traits, such as poodles being bred for intelligence.
Answer:
O A person who experienced malnutrition as a child is short in stature as an adult.
Explanation:
Height is a quantitative trait, i.e., a phenotypic trait that depends on the combined action of many genes and the environment. Moreover, phenotypic plasticity can be defined as the ability of one genotype to produce different phenotypes in different environments. In consequence, quantitative traits are influenced by environmental factors and exhibit phenotypic plasticity. Quantitative traits are characterized to have a large variety of phenotypes and follow a normal distribution (a bell-shaped curve) when they are drawn.
How is DNA created?(short answer)
Explanation:
For a strand of DNA to form, nucleotides must be linked into chains, with the sugar phosphate groups alternating. DNA is made of the building block chemical called nucleotides. Nucleotides are made up of three main parts, a sugar group, a phosphate group, and some type of nitrogen base. Hope this answers, and is helpful! Have a great day! :))

How much more kinetic energy does your car have when it changes its speed from 16 km per hour to 80 km per hour
Answer:
The correct answer would be - 25 times more.
Explanation:
The kinetic energy of a moving object increases with the increase in the speed of the object. It is evident that the kinetic energy of a moving object increases as the square of its velocity or speed. It means if a car moves with the speed of 32 km/hr has four times as much kinetic energy as the car moving with 16 km/hr.
Similarly, if a car changes its speed from 16 to 80 km/hr the kinetic energy will be -
= (80/16)^2
= (5)^2
= 25 times more.
Thus, the correct answer would be - 25 times.
The correct answer would be - 25 times more.

1. The pollutants in our atmosphere have the ability to change the entire planet’s
2. is a theory that states that the increasing carbon dioxide in the atmosphere is causing the climate to warm up.
Answer:
Ans1 Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth
Ans.2 The carbon dioxide theory states that, as the amount of carbon dioxide increases, the atmosphere becomes opaque over a larger frequency interval; the outgoing radiation is trapped more effectively near the Earth's surface and the temperature rises.

How does meiosis create four daughter cells from one parent cell?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell
