Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is <u>Invasive Species</u>.
The process by which a natural ecosystem can no longer support its native species is known as habitat destruction. Reduced biodiversity and species abundance result from the displacement or death of the creatures that once occupied the area. The loss of biodiversity is mostly caused by habitat degradation.
An imported organism that overpopulates and damages its new habitat is referred to as an invasive species. Even though the majority of imported species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.
The most frequent methods for invasive plants, animals, microorganisms, and other species to spread to new ecosystems are thought to be human activities like those involved in international trade and the pet trade.

Answer:
Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
Explanation:
Humoral immunity is defined as the immunity which is mediated by several macromolecules presnet in the extracellular fluids such as antibodies, certain antimicrobial peptides, and complement proteins.
Humoral immunity allows to distinguishes two groups of foreign substances. it involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood. </u>
Humoral immunity begins when an antigens bind to B cells. Interleukins or helper T cells provides a secondary signal to the B cells that activates a B cell and allows B cell proliferation. which roduces produce plasma cells. The plasma cell then produces antibodies which are identical to the specific antigen. The antibodies are the released and circulate through the body, binding to antigens. B cells the further produces memory cellss for future immunity.
So, Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
Answer:
I think this is 2 because there would have been bigger predators in the ocean vs. a lake
Hello There!
As well as the obvious negatives of volcanic eruptions, there are benefits too.
Volcanic eruptions can make the land very fertile.
Also, the lava contains many good minerals.
This makes it an ideal space for farming.
Hope This Helps You!
Good Luck :)

Answer:
Answer is B. It did not reflect the actual evolutionary relationships among organisms very well.
Explanation:
The five-kingdom system of classification was initiated or formed by Robert H. Whittaker in 1969. And it involved the Kingdoms monera, fungi, protista, animalia and plantae.
This classification system was regarded as not so good because of placement of some certain organisms. For example, in the classification system, unicellular algae were put under the kingdom protista, when other multicellular organisms like algae were being classified under the kingdom Plantae.
