Answer:the virus simply can't replicate. Viruses fail the second question for the same reason. ... Finally, a virus isn't considered living because it doesn't need to consume energy to survive, nor is it able to regulate its own temperature.Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Explanation:

Viruses, like bacteria, are microscopic and cause human diseases. ... Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli. They also don't reproduce independently but must replicate by invading living cells.

Which of these scientists is best known for his idea that characteristics an individual gains in its lifetime could be passed on

Anna [14]

This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.

Heterocysts A. are found in nitrogen-fixing cyanobacteria.B. are used to protect nitrogenase.C. produce catalase.D. generate oxy

BARSIC [14]

Answer:

E. are found in nitrogen-fixing cyanobacteria AND are used to protect nitrogenase.

Explanation:

Heterocysts are specialized cellular compartments found in nitrogen fixing cyanobacteria. They provide the ideal anaerobic environment for nitrogen fixation since nitrogenase enzyme cant work in presence of oxygen. Hence, in a cyanobacteria both the oxygen requiring photosynthesis process and the oxygen sensitive nitrogen fixation process takes place simultaneously.

Heterocysts have an additional cell wall made of glycolipid that provides a hydrophobic barrier to oxygen. They are involved in production of nitrogenase and other proteins that are required for nitrogen fixation. They also degrade photosystem II which is responsible for producing oxygen and produce proteins which remove any remaining oxygen.

What is the losing of water from organic molecules, then the joining of these molecules.

Vikentia [17]

Osmosis is a passive transport which moves water molecules from higher to lower gradient.
Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.

The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.
