Meiosis. Sexual recombination. Crossing over. Independent assortment. Mutations.
The two MAIN sources would be genetic(sexual) recombination and mutations. Mutations allow for genetic variation, while genetic recombination allows for genetic shuffling. :)

Flowering plants and shrubs are unable to grow in deciduous temperate rain forests. What is the possible reason for this phenome
Dima020 [189]
The purpose for this wonder is on account of deciduous backwoods are situated close to the north segment of the earth subsequently, have a colder atmosphere that dazes plants from developing at a hoarding rate. Additionally, the daylight is uncommon in this condition which could enormously influence the organic development of these sorts of plants.

I need help on this question in biology and biology is hard and confusing
Yuliya22 [10]

Answer:

b. the new species must be unable to breed with the original species.

Explanation:

By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

  1. Habitat isolation: Two species occupy entirely different and distant habitats.
  2. Temporal isolation: Two species  procreate at different times of the year.
  3. Behavioral isolation: Two species exhibit different mating behaviors.
  4. Gametic isolation: The gametes of the two species cannot fertilize.
  5. Mechanical isolation

Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.

Other factors being equal, which sensory stimulus is least likely to lead to sensory adaptation?
valentina_108 [34]
The correct answer is: the wail of a loud car alarm. 
Sensory adaptation is a term that refers to the changes that stimuli can trigger on the sensory receptors. The process involves changes in the receptors' sensitivity and it is believed that all of the senses exhibit this adaptation. In particular, the sense of touch can quickly adapt to hot and cold stimulation, but not when the stimulus is extremely intense (such as too hot or too cold). Also, our olfactory sense presents the characteristic of odour fatigue. A prolonged exposure to a specific smell leads to a temporary inability to sense this smell and this is a type of sensory adaptation. Finally,
our hearing undergoes a sensory adaptation as well, but not when it comes to sudden, unexpected and instantaneous loud noises. That is why the wail of a loud car alarm will be the least likely to cause sensory adaptation.
