Answer:
Plants are generally considered the best indicators of the level of succession in an ecosystem. Explain how you got your answer.
Explanation:
Plants are generally forms the basis of life in any environment, other organism strictly depends for survival and continuation of life as they are the only autotrophs in the food chain. The best indicator of the level of succession in an ecosystem remains the plant
B. Prokaryotic
C. Nucleus
Prokaryotic cell don't have any membrane bound organelles but they do have a nucleus. Thus, the correct option is B.
Prokaryotic cells are defined as the cell which single-celled, non bound organelle microorganisms known to be the earliest on earth. Prokaryotes comprises bacteria and archaea.
The photosynthetic prokaryotes comprises cyanobacteria that perform photosynthesis. A prokaryotic cell comprises of a single membrane and hence, all the reactions occur within the cytoplasm. The below diagram shows a prokaryotic cell.

Answer:
Dna
Explanation:
The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus
Answer:
It is unchanged and can be used again for the same chemical reaction.
Explanation:Test taken.
After being exposed to the influenza virus, a teenager begins to show symptoms after 4 to 7 days
Answer:
lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within
Explanation:
The influenza virus primarily follows the lytic cycle, causing rapid replication and destruction of host cells.
The influenza virus primarily follows the lytic cycle. After being exposed to the virus, a teenager begins to show symptoms after 4 to 7 days. During the lytic cycle, the virus infects a host cell and takes over the cell's machinery to produce more viral particles. This leads to rapid viral replication within the host cell. As the virus replicates, it eventually causes the host cell to burst, releasing the newly formed viruses. This process results in the destruction of the host cell and the spread of the virus to other cells in the body.

Natural selection is the process by which species adapt to their environment. Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring. Simply put, natural selection is a consistent difference in survival and reproduction between different genotypes, or even different genes, in what we could call reproductive success. [A genotype is a group of organisms sharing a specific genetic makeup.]
B. Exocrine glands release contents into the bloodstream
C. Exocrine glands release contents into ducts
D. Endocrine glands release contents into ducts
Answer:
B
Explanation:
The secretions of the exocrine gastric glands - composed of the mucous, parietal, and chief cells - make up the gastric juice. The products of the endocrine cells are secreted directly into the bloodstream and are not a part of the gastric juice
