systematically assessing natural compounds’ wound healing potential with spheroid and scratch assays
Systematically assessing wound healing assay is a laboratory technique that is used to study the cell migration and the cell to cell interaction.
This wound healing assay is also known as scratch assay because it is done by the doing a scratch on a cell monolayer and by capturing a image on regular intervals by time to time.
This wound healing is of 4 stages and that are homeostasis, inflammation, proliferation and remodeling.
Homeostasis is the self regulating process in which the organisms try to maintain stability.

- What is the role of mRNA in expressing specialized structures?
F Making energy available for cellular activities
G Creating bonds to form biomolecules
H Producing sugars that assist with replication
J
Providing information to form proteins
Answer:J providing information to form proteins
Explanation:
The role of mRNA in expressing specialized structures is providing information to form protein. The correct option is J.
What is mRNA?Messenger ribonucleic acid is a single-stranded RNA molecule that equates to a gene's nucleotide makeup and is read by a ribosome during the protein polymerization reaction.
The function of mRNA is to transport protein details from the nucleus of a cell to the cytoplasm.
Here the protein-making equipment likes to read the mRNA sequence as well as translates each three-base codon into the corresponding amino acid in a burgeoning protein chain.
Messenger RNAs are single-stranded molecules that move genetic information from the nucleus to the cytoplasm, in which proteins are sequenced.
Thus, the correct option is J.

Pick only ONE sentence Which sentence from the section shows why the right temperature is important for plants? (A) Temperature can also affect a plant (B) As with any living thing, a plant has an optimal temperature range at which it grows and preforms best (C) It may not be able to take in enough water and nutrients through it's roots (D) Too much heat can cause plant cells to break down, a process called denaturation.
Answer:
The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.
Explanation:
Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.
Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.

The lumbar and sacral nerves extend inferiorly beyond the end of the spinal cord, they form the Cauda Equina.
What is Cauda Equina?
The cauda equina, a group of nerves near the end of the spinal cord, is so named because it resembles a horse's tail. The top part of the lumbar (lower back) spine is where the spinal cord terminates.
The separate nerve roots that provide the legs and bladder with motor and sensory function continue along the spinal canal at the spinal cord's extremity. These nerve roots continue in the lumbar and sacral region as the cauda equina. These nerves carry signals to and from the pelvic organs and lower limbs.
Cauda equina syndrome (CES) occurs when there is dysfunction of multiple lumbar and sacral nerve roots of the cauda equina.
