Explain the importance of the surface area to volume of ratio

Biology
1 answer:
makvit [3.9K]3 years ago
4 0

Answer:

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

kirill [66]

Answer:

<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>

Explanation:

Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.

Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription.  RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand  and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.

4. The water cycle is balanced because
Sergeu [11.5K]

Answer:

hello!

Explanation:

The water cycle is critical not only to weather, but to life on earth.  Rain is necessary for the survival of plants and humans.  

Condensation is necessary for cloud formation.  Evaporation is necessary to cooling and keeping a good balance of water vapor in the air.

The water on Earth now is the same water that’s been on Earth since the beginning.  

What makes that feat possible?  The water cycle.  The water cycle is the process that re-circulates water so we can have bodies of water as well as clouds and precipitation.

The first step of the water cycle is evaporation. About 85% of the water vapor in the air comes from water that evaporated from the oceans.  The other 15% comes from evapotranspiration, which is a catch-all term for water that evaporates from over land.  

This includes water vapor produced by plants during transpiration, water from lakes, streams, puddles and soil moisture, direct evaporation of snow and even water vapor from the breath of animals.  

The second step of the water cycle is condensation. Now that the atmosphere is full of water vapor, that water vapor condenses into water droplets.  Sometimes, like early in the morning, the water vapor condenses on the grass as dew and seeps back into the soil, ready to be evaporated again.  

But most of the water vapor condenses higher up in the air and forms clouds. Once the water droplets are in a cloud, two things can happen.  Either the cloud will dissipate and the water droplets will become vapor again, or the cloud will grow and it will begin to precipitate.

The third and final step of the water cycle is precipitation. Precipitation includes all water that falls from the sky, both in liquid and frozen form, which reaches the ground.  

Once the precipitation makes its way to the ground it can end up soaking into the ground, run off into streams and lakes, become snow cover, be used by plants, be inhaled by animals or fall directly back into the ocean. Then the water cycle can begin again and continue for millions of years to come.
