Answer:
Seaweed might start to grow out of control withough crabs eating it, octopuses on the other hand would struggle to find food and start to die off because they relie on crabs to be their food source.
<span>An ionic bond is a complete transfer of electrons from one atom to another. This generally happens between atoms that have opposite electronegativity. This means one has very few atoms in their outer shell, while the other has many. A common example of an ionic bond is that of salt, with Na and Cl. Sodium has one electron in its outer shell, in which it transfers to chloride to make an ionic bond.

Ionic bonds are usually found in dry forms such as salts and are found in compounds throughout the human body. Ionic compounds are generally water soluble.</span>
DNA<span> - As you recall, DNA is formed in the shape of a double helix. The double strands of DNA are held together by hydrogen bonds. Each single strand has a backbone made of sugar and phosphate, as well as either a purine (adenine or guanine) or pyrimidine (cytosine or thymine). Each purine is connected to a pyrimidine through a hydrogen bond, giving the double DNA strand strength, and flexibility. This bond holds the two sides of DNA together, each bond contributing to the overall strength of DNA. When DNA is replicated, special enzymes known as DNA helicase "unzip" DNA and these bonds are broken so the two strands can be individually replicated.</span>
<h2>Prezygotic barriers </h2>
Explanation:
Two potential prezygotic barriers that may be contributing to the divergence and speciation of these two populations of flycatchers are behavioral isolation and habitat isolation
- A prezygotic reproductive barrier is a mechanism that prevents fertilization from occurring
- Behavioral isolation means many species perform different mating rituals for reproduction,for example mating calls of both flycatchers may be different
- Habitat isolation is a type of prezygotic barrier in which two species that could interbreed because the species live in different areas,here in this case flycatchers are living on two different islands and hence cannot mate which results into divergence of two different species
Evidence that would indicate that speciation has already occurred within the flycatcher populations is geographic patterns which resulted into allopatric speciation
- Flycatchers are isolated from each other by geographical barriers because they are located on two different islands
- As they are geographically isolated from each other speciation which occurs is allopatric
The cell cycle is regulated at the molecular level by a set of protein known as CYCLIN . Cyclin are a core regulator of the cell cycle. They are group of related proteins and four different types have been identified in humans. Each cyclin is associated with a particular phase of the cell cycle.
