What three key features allow prokaryotic populations to consist of trillions of individuals?

Biology

Andreas93 [3]3 years ago
4 0
I think the features are that, prokaryotes are small, they produce by binary fusion and that they have short generation times. Prokaryotes are unicellular organism that lack membrane bound nucleus, mitochondria or any other membrane bound organelles. Prokaryotes reproduce asexually through binary fission which is a kind of reproduction that occurs in bacteria and other single celled eukaryotes such as Amoeba. The body separates into two new bodies and  where the body/organism duplicates its genetic materials or DNA and then divides into two parts, with each new organism receiving one copy of DNA.

Free_Kalibri [48]

Answer:

somatic nervous system

Explanation:

The motor division of the peripheral nervous system includes a somatic nervous system and an autonomic nervous system. The somatic nervous system (SNS) delivers motor information from the central nervous system to skeletal muscles only. Therefore, the motor responses of the somatic nervous system are consciously controlled by humans. This makes it control the voluntary actions of the body. The somatic nervous system includes the somatic motor neurons that connect the skeletal muscles with the central nervous system.

What is happening to the DNA molecule in the figure? (Explain the first step in DNA replication)
tatuchka [14]

Answer:

As this is DNA replication, this is the unwounding process

Explanation:

In DNA replication, the parent DNA to be replicated is unwound to enable access of the replication machinery (replisome) to this genetic material. The origin of replication will be identified first, which in the prokaryotes is only one, and in the eukaryotes, we have many. This sites are recognized by specific sequences on the genome. after this, melting of the DNA occurs at this origin creating a replication bubble and two replication forks. This  allows for the unwinding of the DNA by the enzyme Helicases in the direction of the replication fork. Another enzyme present in this step is also the single strand binding proteins (SSB). These proteins function in the prevention of re-anealing of the unwound DNA strand by attaching themselves to each strands. Another enzyme called the topoisomerases also function here by reducing the torque (twisting) produced upstream of the replication fork as result of DNA unwounding. An example is the gyrase

Plant viruses spread throughout the plant by way of __________. View Available Hint(s)for Part A chloroplasts plasmodesmata vert
KatRina [158]

Answer:

Plasmodesmata

Explanation:

Plasmodesmata are microscopic channels which traverse the cell walls of plant cells and some algal cells, enabling transport and communication between them. This is the path that viruses use to spread throughout a plant's system.

Hope this helped! :^)
