The amount of air that remains in the lungs to keep them open is called the functional residual capacity (FRC).
It is a vital measure of lung function and plays a crucial role in maintaining proper respiratory mechanics.
The functional residual capacity (FRC) represents the volume of air that remains in the lungs at the end of a normal tidal breath, when the individual is at rest and not actively breathing in or out.
It is the equilibrium point between the elastic recoil of the lungs (which tends to collapse the lungs) and the elastic recoil of the chest wall (which tends to expand the lungs). The FRC consists of two components: the expiratory reserve volume (ERV), which is the volume of air that can be exhaled after a normal exhalation, and the residual volume (RV), which is the volume of air that remains in the lungs after a maximal exhalation. The FRC is essential for maintaining the patency of the airways and preventing lung collapse, ensuring that the lungs are ready for the next breath.

air passes from the nose into the bronchi true or false?
Answer:
True
Explanation:
The right lung has 3 sections called lobes and is a little larger than the left lung, which has 2 lobes. The bronchial tubes divide into smaller air passages called bronchi. The functioning of the lungs is discussed in detail.

What leads to variation in a population?
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Water vapor may be defined as the gaseous form of water that is usually dispersed across the atmosphere with the help of wind. This state of water is significantly found in the hydrosphere.
This gaseous form of water is formed from the evaporation or boiling of liquid water or from the sublimation of ice.
Water vapor requires to combine with dust particles and cool air along with atmospheric humidity in order to produce rain or snow. Due to the combination of such compounds, water droplets become too heavy.
Snow or ice is the solid appearance of water which is usually formed from the compaction of crystallized structure.
Therefore, each of the above questions is described.

What is bacterial conjugation?
Answer:
Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. This takes place through a pilus. It is a parasexual mode of reproduction in bacteriaThe picture below shows four locations and their temperatures. The temperature in each location is given in Celsius. Answer the question using what you know about heat transfer and how it ALWAYS travels.

In a herd of beef cattle, the average yearling weight of all animals was 800 lb when corrected to a bull basis. Bulls and heifers kept for breeding weighed 1000 and 825 lb, respectively. The progeny of those individuals selected for breeding had an average yearling weight corrected to a bull basis of 845 lb. What is the apparent genetic control of the trait
Answer:
Explanation:
The trait is genetic and not dependent on environment. When a trait is dependent on the genetic component of the parental generation, the ability of the traits to be passed from a generation to another is high and this will be revealed in their resemblance with the parent. Hence, the case of the offspring with an average weight of 845lb.
If the trait is controlled or influence by the environment there will be a difference when the offspring is produce because until the same environment is given to the offspring the trait cannot be expressed.

It is proper to put the _____________ allele before a recessive allele when determining the genotype of the offspring in a Punnett square.
Answer:
dominant
Explanation:
the dominant allele is the capital letter (for example, T) whereas the recessive allele is the lowercase letter (for example, t). the dominant allele is usually written first.
It is proper to put the dominant allele before a recessive allele when determining the genotype of the offspring in a Punnett square.
What are alleles?Alleles are the variation present in the gene or DNA sequence. It is the sequence of nucleotides that encodes the production of the product of a gene.
There are two types of alleles, dominant and recessive, the dominant gene is denoted by a capital letter, and it is placed before the recessive allele.
Thus, in a Punnett square, the dominant allele should come before the recessive allele when determining the genotype of the offspring.
