Second-degree burn is the type of burn represented by the formation of the blisters.
Second-degree burn is a burn that affects the epidermis and the superficial part of the dermis layer (skin). Second-degree burn may be caused by sunburn, chemicals, scald injuries, flames or electricity. The burn site may appear blistered, red, wet and shiny, and may be swollen and painful.
Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —. Contamination of the food chain.Human diseases: Pathogens(viruses,bacteria,fungi,protozoa etc)are biological pollutants of water. They cause typhoid,cholera,dysentery,jaundice,hepatitis.
HOPE IT HELPS
PLEASE MARK ME BRAINLIEST ☺️
Answer:
B. sheet of connective tissue that attaches a muscle to another muscle or bone.
Explanation:
The aponeurosis are mainly made of collagen fibers and works as an insertion to some skeletal muscles. The aponeurosis fibers can connects muscles to the bone or with another muscles connecting the aponeurosis fibers among themselves.
Lol i dont know but i will still get points
Answer:
It seems that a reciprocal translocation is going on.
Explanation:
A translocation occurs when a chromosomal fragment changes its location in the same chromosome from the original to a new one. Or when it leaves the chromosome to re-locate in a new different chromosome.
According to this, there are different types of translocations:
- Intrachromosomal translocations:
- Intra-radial: the change in position occurs in the same arm of the chromosome. For instance, 123.456789 → 123.478569
- Extra-radial: The change in position occurs from one arm to the other of the same chromosome. For instance, 123.456789 → 15623.4789
- Extrachromosomal translocations:
- Transposition: not reciprocal interchange. The fragment leaves a chromosome to re-locate in another chromosome. The other chromosome does not send any fragment to the first one.
- Reciprocal translocation: There is a reciprocal interchange. A fragment of chromosome A goes to B, and a fragment of chromosome B goes to A.
Reciprocal translocations might be:
- Fraternal: the interchange occurs among homologous chromosomes
- External: the interchange occurs among non-homologous chromosomes
Reciprocal translocations are easily recognized during meiosis because an association between four chromosomes can be observed. This association is a quadrivalent structure.
During metaphase 1, the centromeres involved in the quadrivalent originate centromeric co-orientation or disjunction.
