While a fresh brain is very soft, the brains that are treated for a long-term storage and observation is firm.
<h3>What sort of storage is long-term?</h3>
Long-term storage does precisely what it says on the tin: it provides you with a location to store items you need safely hidden for a protracted period of time, typically anything longer than three months. There are several things to keep in mind when placing items in long-term storage: Be careful not to pack anything in plastic shopping bags.
<h3>What are organs kept in?</h3>
The currently accepted technique for organ preservation is static cold storage (SCS). The length of time that can be preserved with SCS, though, is constrained because prolonged cold storage raises the risk of early graft dysfunction, which feeds into chronic complications.

<u>Answer</u>:- Option B Brown
<u>Explanation</u>:-
- When the beetles are living in a vegetation, then the most important point is that they are living in an environment where <em>green is the predominant color.</em>
- Since, the birds who will come to look for food, will have to identify the beetles against a green backdrop the green beetles are <em>most</em> safe as they can easily merge with their green surroundings. This is known as camouflage.
- The mixed beetles will be less fit as compared to the green beetles as the chances of them to be identified by the birds will be more as they are not completely green and are not able to fully merge with the surroundings.
- However, the brown beetles will be <em>least</em> fit to survive in this environment as they can be most easily identified against the green backdrop. They will be the most conspicuous of the three beetles. Thus, the birds will feed more often on the brown beetles and hence, they are least fit to survive in the vegetation.
This phenomena in which the organism who is best adapted to survive in a given environment and leave more progeny is termed as <em>survival of the fittest.</em>
Answer:
Pinocytosis can be recognized when the CELL IS ENGULFING EXTRACELLULAR FLUID
Explanation:
Pinocytosis is the process whereby the cell takes in macromolecules such as bacteria and antigens in form of fluid from the extracellular fluid.
The macromolecules in the form of droplets of fluid bind to the outer surface of the cell
The cell membrane enviginates around the droplets of fluid and are engulfed by the cell.
They form vacuoles with the macromolecules and are transported into the inner of the cell.
The formed structure is called ENDOSOMES which lysozomes combine with and form secondary endosomes containing enzymes to break down the macromolecules.
Pinocytosis is also called CELL DRINKING.
Spontaneous miscarriage in the first trimester is related to Chromosomal defects in the fetus. An estimated 15 to 20 percent of known pregnancies end in miscarriage, the loss of a pregnancy before the 20th week. Upto 70 percent of first-trimester miscarriages, and 20 percent of second-trimester miscarriages, are caused by chromosomal anomalies/abnormalities in the fertilized egg. Most often, it means that the egg or sperm had wrong number of chromosomes, and consequently the fertilized egg can't develop normally.
If ΔG is negative, the reaction is always spontaneous.
If ΔG is positive, the reaction is non-spontaneous and will require a sustained input of energy for it occur.
If ΔG is zero, the reaction is at equilibrium and no work can be done.
