Answer:

a. a set of proteins involved in innate but not acquired immunity.

Explanation:

The complement system are a set of proteins or protein fragments that play a major role in the innate immune system. The complement system is involved in the defense of the body from foreign pathogen through specific plasma proteins that participate in leukocyte activation, chemotaxis and opsonization. In other words, they increase the ability of phagocytes and antibodies to mop up damaged cells and foreign microorganism, activate inflammation process.

What is meant by aseptate coenocytes​
spayn [35]

Answer:Filamentous fungi may contain multiple nuclei in a coenocytic mycelium. A coenocyte functions as a single coordinated unit composed of multiple cells linked structurally and functionally, i.e. through gap junctions. Fungal mycelia in which hyphae lack septa are known as "aseptate" or "coenocytic".

Coenocytic cells are present in diverse and unrelated groups of algae, including Xanthophyceae, red algae and green algae.

In the siphonous green algae Bryopsidales and some Dasycladales the entire thallus is a single multinucleate cell, which can be many meters across. However, in some cases, crosswalls may occur during reproduction.

Explanation:The green algal order Cladophorales is characterized by siphonocladous organization, i.e., the thalli are composed of many coenocytic cells.

In contrast to the Cladophorales where nuclei are organized in regularly spaced cytoplasmic domains, the cytoplasm of Bryopsidales exhibits streaming, enabling transportation of organelles, transcripts and nutrients across the plant.

One reason why small patches of protected land could be disadvantageous is ____.
Veseljchak [2.6K]

C. It would make it for difficult for animals to move around and seek resources in other areas.

Explanation:

Small patches of protect land makes it difficult for animals to move around and see resources in other areas.

Protected areas or conservation areas are locations that receive special protection because of the natural diversity found in them.

  • Protected areas in some places are the last refuge for animals and plant species for safety.
  • The larger a protected area is, the better and more advanced an organisms niche can be.
  • A small protected area limits the niches of roaming animals and makes it difficult to seek for resources out of their limited scope.
