The right answer is C
"Binary fission" is the most common form of reproduction and cell division of prokaryotes. A cell, after replicating its genetic material, divides into 2, each part containing a copy of the genetic material and 2 new perfectly individualized cells are finally created, each having the ability to grow to the size of the parent cell of origin ... The chronology is as follows:
- replication of the bacterial chromosomal DNA and segregation into two nucleoids and cell growth phase;
- assembly of a protein ring of constriction;
- constriction of the ring associated with the wall synthesis until complete individualization of the 2 new cells.

Answer:
2 unit
Explanation:
According to the 10% law, the transfer of biomass energy from one higher trophic level to lower trophic level is only 10%.
Primary(Producer)→Primary consumers→secondary consumers→tertiary consumers.
that is 2000→200→20→2
note: only 10% of the total biomass is received by the next trophic level.
therefore tertiary consumers will receive 2 units of biomass.
B) the introduction of disease into the New World
C) the introduction of the slavery into the New World
D) conflict and warfare between European settlers and Native Americans
b. producers
c. the sun
d. water
Answer:
The correct answer would be c. the sun.
The sun is the ultimate source of energy in any ecosystem.
The solar energy is converted into chemical energy with the help of autotrophs or producers through the process of photosynthesis.
The small portion of this energy is transferred to the next trophic level and by end of 3-4 trophic levels, the entire energy is lost as heat or cellular respiration.
The sun is the ultimate source of energy in most ecosystems. This energy is transformed by producers like plants into a usable form through photosynthesis. Water and plants also have important roles in this process.
In ecosystems, the ultimate source of energy is typically the sun. The energy from the sun is initially harnessed by producers, or autotrophs, such as plants, through the process of photosynthesis. These organisms convert light energy into chemical energy that can be used by other organisms. Water and plants also play crucial roles in ecosystems. Water is necessary for photosynthesis, and plants are vital for converting the sun's energy into a form that other organisms can utilize.

B. lived only in volcanic regions, and were destroyed by lava flows.
C. were soft-bodied and tiny, therefore unlikely to fossilize.
D. had hard shells that broke down easily, leaving no trace
