The answer is; Sodium (Na+) and Potassium (K+) Ions


These cations are pumped out of the cell by Na+-K+ transmembrane protein pumps leaving the inside of the cell electronegative in relation to the extracellular matrix. This membrane potential is significant especially for neurons. Depolarization of the membrane enables transmissions of an impulse along the neurons.

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.

Amiraneli [1.4K]

Answer:

1, 2, and 5

Explanation:

Viruses are pathogenic microorganisms that lack the ability to thrive and reproduce outside of a living host cell. Their structure is simple - they consist of a nucleic acid molecule surrounded by a protein coating and sometimes an outer envelope. They are too small to be seen by a light microscope.

As they are way smaller than living cells, viruses are smaller than organelles as well. They don't have their own metabolism. Their reproduction is not based on division. They don't have any organelles, including the cytoplasm. They are surrounded by a protein coat called the capsid.

Based on this information, we can see that the correct statements are statements 1, 2, and 5.
