Answer:
water vapor, dust and ash particles
Most food chains are limited to three or five trophic levels because the energy available is only enough for those number of trophic levels: there is insufficient energy to go round more trophic level. At each trophic level, a large quantity of energy is used to maintain organisms at that level, because of this, organisms at one trophic level, pass less energy to the ones at the next trophic level. <span />
Answer:
<h2>Anaphase</h2>
Explanation:
Cell cycle is divided into two main phases: i) inter-phase and ii) mitotic phase
Inter-phase is further divided into three phases named as G1, S and G2 phase, it is the phase where DNA replication and other duplication processes occurs, and in this phase cell prepare itself for division.
Mitotic phase, this phase is further divided into four sub-phases named as prophase, metaphase, anaphase and telophase.
In anphase, during cell division, sister chromatids are separated as they are pulled apart by spindle fibers towards opposite poles.
Answer:
Gene flow.
Explanation:
When individuals migrate, alleles can be transferred from one population to another population which is known as gene flow. Gene flow is also called gene migration, the introduction of genetic material through interbreeding from one population of organisms to another which changes the composition of the gene pool of the migrated population of organisms. This gene flow creates a new species that is different from previous population of organisms
