The initiating event in the development of nephrotic syndrome is a derangement in the glomerular membrane that causes increased permeability to plasma proteins.
Nephrotic syndrome can be understood as a kidney disorder in which the glomeruli filter of the kidney gets damaged due to which it is unable to filter the proteins and passes an excess amount of protein in the urine.
Glomeruli filter consists of clusters of small blood vessels in the kidneys that function in filtering the waste and excess water from the blood. It also sweeps the blood protein which is necessary to maintain the correct amount of fluid in the body, from seeping into the urine. But when it gets damaged glomeruli stop sweeping the protein from the urine as a result too much blood protein leaves your body, leading to nephrotic syndrome.

Answer:
An axis is an invisible line around which an object rotates, or spins. The object can be a tiny particle, smaller than a single atom. Or it could be a star with the mass of a thousand suns.
Answer: DNA is a molecule made up of two strands, twisted around each other in a double helix shape. The two strands are complementary which have a 5 prime end and a 3 prime end. To understand this question you must first understand the steps that follow.
DNA Replication:
<u>Step one: </u>
DNA Helicase (unzips) separates the strands.
<u>Step two:</u>
DNA Primase starts the process and makes a small piece of RNA called a primer. This marks the starting point for the DNA.
<u>Step three:</u>
DNA Polymerase binds to the primer and will make the new strand of DNA. DNA Polymerase can only add DNA bases in one direction, from the 5 prime end to the 3 prime end.
- The leading strand is made continuously.
- The lagging strand does not run continuously because it runs in the opposite direction. Each fragment is started with an RNA primer. DNA Polymerase then adds a short row of DNA bases from the 5 prime to 3 prime direction. This results in okazaki fragments because it can only replicate in small chunks. The process is repeated.
<u>Step four:</u>
Once the new DNA is complete the enzyme exonuclease removes all the RNA primers from both strands of DNA.
<u>Step five:</u>
Another DNA Polymerase fills in the gaps that are left behind with DNA.
<u>Step six:</u>
DNA Ligase seals up the fragments in DNA, in both strands to make a continuous double strand.
<u>Final answer:</u>
DNA Replication cannot replicate at the same time due to the leading and lagging strand.
Good luck!
This is an example of co-evolution.
<u>Explanation:</u>
In co-evolution one species or a number of species evolve according to the changes in another species. Here the evolution of the beak of humming bird according to the shape of Ossifloramixta flower is an example of co-evolution. Co-evolution is common in the nature.
Bees, insects and butterflies commonly co evolve with the flower plants and vice versa. Co-evolution is of two types. The first type is specific co – evolution where only two parties are involved in co-evolution. In the second type of co-evolution namely diffused co-evolution many species evolve in response to specific traits in a species.
