Bats and birds eating insects at different times of day is an example of (1 point)
O survival of the fittest.
O resource partitioning.
O competitive exclusion.
O natural selection.

Answers

Bats and birds eating insects at different times of day is an example of Resource Partitioning. So, the correct option is B.

What is Resource Partitioning?

Resource partitioning or niche differentiation is a process of natural selection that will force competitors to use resources differently in such a way as to avoid competition between species. Resource partitioning causes the co-existence of species.

If bats and birds eat insects at different times of the day, there is no survival of the fittest. Competitive exclusion states that no two species can co-exist in the same niche for a long time.  

Therefore, bats and birds eating insects at different times of day is an example of Resource Partitioning.

What are the characteristics of kingdoms archaebacteria?

Answers

Answer:

Archaebacteria are obligate or facultative anaerobes, i.e., they flourish in the absence of oxygen and that is why only they can undergo methanogenesis.

The cell membranes of the Archaebacteria are composed of lipids.

The rigid cell wall provides shape and support to the Archaebacteria. It also protects the cell from bursting under hypotonic conditions.

The cell wall is composed of Pseudomurein, which prevents archaebacteria from the effects of Lysozyme. Lysozyme is an enzyme released by the immune system of the host, which dissolves the cell wall of pathogenic bacteria.

These do not possess membrane-bound organelles such as nuclei, endoplasmic reticulum, mitochondria, lysosomes or chloroplast. Its thick cytoplasm contains all the compounds required for nutrition and metabolism.

They can live in a variety of environments and are hence called extremophiles. They can survive in acidic and alkaline aquatic regions, and also in temperature above boiling point.

They can withstand a very high pressure of more than 200 atmospheres.

Archaebacteria are indifferent towards major antibiotics because they contain plasmids which have antibiotic resistance enzymes.

The mode of reproduction is asexual, known as binary fission.

They perform unique gene transcription.

The differences in their ribosomal RNA suggest that they diverged from both prokaryotes and eukaryotes.

Answer: Archaebacteria are obligate or facultative anaerobes, i.e., they flourish in the absence of oxygen and that is why only they can undergo methanogenesis.
