How does dispersal help different species? dispersal helps different species to increase their range of places, thereby helping
icang [17]

Dispersal helps different species to increase their range of places, thereby helping to increase their population size in different regions. Dispersal also helps to avoid crowding of diseases of a single location as species move to different locations.

<h3>What is dispersal?</h3>
  • Dispersal is the act of distributing things over a large area. It is when the individuals or seeds move from one site to their growing site.
  • Dispersal can be active (move by oneself) or passive (require dispersers).
  • Seed dispersal is the mechanism of transport of plant seeds to new sites for germination and the establishment of new individuals and colonies.
  • This depends upon the effectiveness of the seed dispersers.
  • Seed dispersal occurs by wind, water, animals, bats, explosions or gravity of the earth.
  • Dispersal of seeds is very important for the survival of plant species.
  • If the plants of same type grow too closely, they have to compete with each other for light, water and nutrients from the soil.
  • Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.

Why is it incorrect to say the insulation 'keeps out the cold'
Sonja [21]
Because technically there is no such thing as cold
all that exists is heat
this is because heat is the rapid movement of particles, made by friction (to understand why you must delve into physics and some chemistry)
so, when you feel cold, it's really the absence of heat
so instead of "keeping the cold out", which makes no sense at all scientifically, insulation keeps the heat in.

as a side note
the feeling of cold is produced when you come in contact with an object (yes, air counts) that has less heat, or energy, than you do, You feel cold because heat (energy) from your body is being transferred to the environment. This ABSENCE OF HEAT in your body is why you feel cold

Classify each RNA post-transcription processing event according to whether it occurs in prokaryotes or eukaryotes.
tigry1 [53]

'RNA is transcribed and translated in the cytoplasm', 'transcription produces an mRNA ready for translation' and 'RNA is proofread for errors' occur in prokaryotes, whereas '5′ cap, 3' poly-(A) tail and RNA splicing' occur in eukaryotes.

The prokaryotic cells (e.g., bacterial cells) do not contain cell nuclei, thereby the messenger RNA (mRNA) must be transcribed and translated in the cytoplasm.

During prokaryotic transcription, the RNA transcript is proofread for errors. In bacteria, DNA polymerases proofread the transcript by using their 3’ → 5’ exonuclease activity.

In eukaryotic cells, RNA processing consists of several mechanisms:

  • A 7-methylguanosine cap (5′ cap) is added to the 5′ end of the precursor messenger RNA (pre-mRNA).

  • A 3' poly-Adenine (A) tail is added to the 3' end of the pre-mRNA.

  • Both the 5′ cap and 3' poly-(A) tail protect the RNA transcript from its degradation by exonucleases.

  • Eukaryotic RNA splicing consists of the removal of non-coding regions called 'introns' and subsequent splicing of the protein-coding regions called 'exons'.
