A typical trachea (windpipe) includes several cartilage rings (a strong and flexible tissue). These C-shaped rings support the trachea while allowing it to bend and move during your child's breathing.
Why are the trachea's cartilage rings not closed?To safeguard and keep the airway open, C-shaped cartilaginous rings are reinforced on the trachea's anterior and lateral sides. (The incomplete cartilaginous rings allow the trachea to slightly collapse, allowing food to travel down the oesophagus.)
to allow the oesophagus to expand when food passes through it on its journey to the stomach and prevent the trachea from closing and restricting the airway.
The trachea is located behind the oesophagus. The trachea might collapse thanks to the C-shaped cartilaginous rings.

Filtrate flow through the renal tubule increases when glomerular filtration rate.
When glomerular filtration rate increases, the flow of filtrate through the tubule increases.
Urine production starts with glomerular filtration. It is the procedure your kidneys utilize to filter extra fluid and waste from your blood into the kidney's urine-collecting tubules, allowing your body to discard them. When GFR rises, the sodium concentration in the filtrate rises; when GFR falls, it will fall. Increase the flow rate to release more Na+ into the urine. Hydrostatic pressure and colloid osmotic pressure both affect the GFR. Under normal conditions, hydrostatic pressure is much higher and filtration takes place.
Hence, glomerular filtration rate increases flow of renal tubules.

In a paragraph (5 sentences minimum) describe the process of protein synthesis and explain how transcription and translation generate proteins.
The process of protein synthesis involves the presence of ribosomes that provide the machinery for the t-RNA to read the codon on the m-RNA and attach the correct amino acid accordingly to the growing polypeptide chain. Transcription is the process where m-RNA is formed from the DNA and then further from m-RNA protein synthesis i.e., translation happens.
Ribosomes are the nucleoproteins. They are comprised of r-RNA and proteins. They have two subunits, one large and one small that join together at the time of protein synthesis.
t-RNA is also called the adaptor molecule in protein synthesis. It contains the anticodon at one terminal that recognizes the codon on m-RNA strand and therefore the appropriate amino acid is attached.

which type of transport would be best if the cell needs to respond to a sudden concentration gradient difference
Diffusion is the optimum kind of transport if the cell needs to react to a quick concentration gradient difference. As the concentration difference widens, the rate widens as well.
Why does assisted diffusion plateau at increasing concentrations?Due to the carrier's role, assisted diffusion normally moves along more quickly than simple diffusion at low solute concentrations. The enhanced diffusion will level off at larger concentrations because the carriers will get saturated.
What cellular transport strategy maintains a high concentration?The accumulation of large concentrations of substances that the cell requires, such as ions, glucose, and amino acids, is typically linked to active transport. Primary active transport is a term used to describe a process that employs chemical energy, such as that from adenosine triphosphate (ATP).

if a couple that are both heterozygous carriers of the cystic fibrosis allele have children, the chance that both their first and their second child are carriers is 0.5 x 0.5, or 25%, as determined by the_______
If a couple that is both heterozygous carriers of the cystic fibrosis allele have children, the chance that both their first and second child will be carriers 1/4 or 25% is as determined by the crossing.
Monohybrid crossingThe cystic fibrosis condition is a recessive one. Let's assume that the allele for cystic fibrosis is a for the affected and A for the unaffected.
A couple that is both heterozygous would have Aa as their genotype:
Aa x Aa
AA Aa Aa aa
The genotypes and phenotypes of the offspring would be as follows:
AA = unaffected
Aa = unaffected
aa = affected
Chances of an offspring being affected = 1/4 or 25%
Chances of an offspring being affected = 3/4 or 75%
Chances of an offspring being a carrier = 1/2 or 50%
Now, let's calculated the probability.
Probability of the first child being a carrier = 1/2
The probability of the second child also being a carrier = 1/2
The probability of both their first and second child being carriers = 1/2 x 1/2
= 1/4 or 25%

Convective heat transfer is the process by which heat is transferred from one body to another by currents of flowing gas or fluid. As it flows away from the heated body, air or water rises and is replaced by a cooler parcel in the process of free convection.
Temperature differences within the fluid cause convection. Because of the increased energy of the particles, a fluid loses density at the area nearest to the heat source as it is heated. The less dense portion of the fluid then rises, while the denser portion sinks.
