Answer:
The cell organelles are the functional structures present inside the cell. Some of the organelles such as nucleus, mitochondria, chloroplast, Endoplasmic Reticulum, Golgi Complex etc are membrane-bound. Each organelle inside the cell has a different function to carry out. For example, the nucleus is the organelles which stores and protects the genetic material. Ribosomes are the organelles where a protein is formed. The Golgi- complex is the site where the proteins are modified and packaged.
Answer:
Prezygotic barriers:
1. Habitat isolation
2. Behavioral isolation
Explanation:
Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.
The two mechanisms of the pre-zygotic barriers are the:
1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.
2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.
Thus, Habitat isolation and Behavioral isolation are correct.
the correct answer is the first one. density = mass / volume.

During a flood, many individuals in a population of gophers drowned. Which effect of an environmental change does this best <span>illustrate? The answer is DEATH</span>
Dimorphic, polymorphic, and continuously variable traits are distinguished as follows:
- Dimorphism is the condition of those<em> species</em> of animals or plants that exhibit two anatomical aspects or two different forms.
- When talking about polymorphisms in genetics, reference is made to the different variations that may exist on the DNA of the same gene.
- Continuously variable traits are those that show a continuous distribution of phenotypes.
Therefore, we can conclude that dimorphism is a polymorphism with only two forms, the polymorphism is any stable change of the DNA fixed in the population and in continuously variable traits the phenotypes show a continuous series and cannot be easily grouped.
