The evolutionary theory that suggests that a species can suddenly and rapidly evolve into a new species is ?
Mekhanik [1.2K]

<span>Punctuated Equilibrium/ Equilibria proposes that once species appear in the fossil record, the population  will be in the state of little or absent morphologic change. This is called a state of stasis. The theory further proposes that the population is confined to infrequent and geographical rapid events when significant evolutionary change happens.  The parent species will the split into two distinct species. This process if called cladogenesis.</span>

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.

In easy steps describe protein synthesis
Goryan [66]
<span>The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cell's nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.</span>
