Answer: True
Explanation:
Mucociliary streaming is the process of the cleaning mechanism of the respiratory passage. It is one of the protective process that protects the respiratory passage from the effect of the particles of dust and pathogens before they reach up to the delicate lung tissues. This process maintains the pulmonary hygiene.
This takes the advantage of cleaning up the cilia present in the respiratory tract, this process penetrates the mucous layer of the cilia by wave-like motion. The cilia trap the large and small particles. The instrument used for this purpose moves at a speed of 6 to 20mm per minute. This helps in cleaning up of the cilia along with the mucous.
Answer:
Some examples of decomposers include bacteria, fungi, and some insects. If decomposers disappeared from a forest ecosystem, wastes as well as the remains of the dead organisms would pile up, and producers (plants) would not have enough nutrients.
Yes it does, they are everywhere
Answer:
G and K
Explanation:
Crossing-over is a genetic phenomenon that occurs in meiosis, specifically, Prophase I. It is when chromosomal segment (genes) are exchanged between non-sister chromatids of homologous chromosomes. Crossing-over occurs only to genes that are UNLINKED i.e. genes located on different chromosomes or far apart on the same chromosome.
This unlinked genes are said to have the highest RECOMBINATION FREQUENCY. Crossing-over allows genes on the same chromosome but far apart from each other, assort independently, which allows alleles to be recombined on the same chromosome. This phenomenon does not occur to genes that are close on the same chromosome as they will be inherited together as a unit.
In this case, G and K are the farthest apart, hence, they will have the highest RECOMBINATION FREQUENCY i.e. the likelihood for homologous crossing-over to take place during meiosis.
