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:
Building desalination plants and using rain gauges.
Explanation:
Using the process of elimination, seismographs are incorrect because they measure earthquakes and obviously earthquakes have nothing to do with droughts (ok, maybe a little bit). Snowplows are used to plow snow, so the remaining answers should be correct.
Answer:
B) 15mi/h
Explanation:
In general, you can just look at a road sign and see that usually, that's how the speed limits are provided.
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.

The spores release from the gametophyte
The gametophytes grow directly from the sporophyte
The spores release from the male cones

Answer:
The correct answer is The gametophytes grow directly from the sporophyte.
Explanation:
Conifers are a group of plants that belong to what is called Pinophyta.
They abound in quantity in cold areas although many different types of this plant can also be found in tropical areas.
They are formed by live gemnosperm plants, this means that their seeds do not form in closed cavities but are "naked". These seeds are evergreen, this means that their leaves will not fall throughout the year and usually live for more than two years or produce other seeds again.
Gametophytes are haploid plants that are usually located in or below the soil and are responsible for producing gametes.
These grow directly from the sporophyte, which is the phase in which a plant reproduces by spores.
So we can say that the correct answer is The gametophytes grow directly from the sporophyte.
Answer:
The gametophytes grow directly from the sporophyte - third choice
