Coralline and calcareous algae build-ups are very essential for the development of coral reefs. In addition, when these coralline and calcareous algae tends to "stick" on landforms below the ocean surface, and as these life forms grows and continuously expands, they now form what we call "reefs."

A desert plant called Kalanchoe can reproduce, either with sexual reproduction through flowers, or asexually by budding off mini
AnnyKZ [126]

Answer:

The correct answer will be- will be called "Clones" with no genetic variation thus result in less adaptability to environment.

Explanation:

Plants can reproduce by both modes of reproduction called asexual and sexual reproduction.   The asexual mode of reproduction produces genetically similar offsprings in less period of time and thus helps in spreading of the species in minimum time as in the case of Kalanchoe.

The Kalanchoe can dominate a large area of the habitat using this mode of reproduction but at the cost of genetic variation.  

Since asexual reproduction results in Clones with same genetic material so the descendants of the plant will be less adaptive to changing the environment as asexual reproduction does not involve genes.

Which of the following is NOT a component of a nucleotide?
Paha777 [63]

Answer:

Option D.

Explanation:

The above answer given is incorrect. Nucleotides consist of a phosphate group attached to a pentose sugar, with 5 carbons,  (deoxyribose sugar in the case of DNA) and the pentose sugar is also attached to a nitrogenous base. DNA is incorrect as nucleotides are the building block of DNA hence DNA is NOT a component of nucleotides.
