JulijaS [17]

<u>Answer:</u>

<em>Decrease in burning of fossil fuels will affect carbon cycle the most. </em>

<u>Explanation:</u>

Carbon compounds circulate within the biosphere as part of carbon cycle.  In terrestrial ecosystems Plants acquire carbon dioxide through photosynthesis and in aquatic ecosystems plankton absorb carbon dioxide.  

Dead plants bodies deposited underground for a large number of years get converted to fossil fuels and the burning of these fossil fuels releases carbon dioxide into the atmosphere.

Carbon dioxide is also released into the atmosphere through processes like respiration and decomposition of dead organic matter. If burning of fossil fuels is decreased it will be the carbon cycle which will be affected the most.

Diferencia entre las bacterias y los virus.
myrzilka [38]

Answer:

Los virus son más pequeños y no son células. A diferencia de las bacterias, necesitan un huésped como un humano o un animal para multiplicarse.

Las bacterias son organismos vivos unicelulares. Tienen una pared celular y todos los componentes necesarios para sobrevivir y reproducirse. Los virus no se consideran "vivos" porque requieren una célula huésped para sobrevivir a largo plazo, para obtener energía y para reproducirse.

Which three of the following entities are acellular?.
arsen [322]

Answer:

Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.

While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood. 

Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.

Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.

Diastolic blood pressure is the pressure of the blood between heartbeats (when heart is not active, relaxed). Normal diastolic blood pressure is about  80 mmHg.

SCORPION-xisa [38]

Answer:

You tell her that this is incorrect.

Explanation:

The given information is incorrect as both small and large ribosomal subunits are required for protein synthesis. The eukaryotic ribosomes have E, P, and A sites. The A and P sites bind to the aminoacyl tRNA that carry the amino acid encoded by the codon of the mRNA.

The formation of peptide bond occurs between the amino group of amino acid in A site and the carboxyl group of amino acid present on P site. Both 40S and 60S subunit of ribosome contribute the A and P sites.
