D. recessive
E. polygenic

Answer: E. Polygenic

Explanation: The color of eyes and hair is due to quantity and accumulation of pigments such melanin. Melanin is synthesize by multiple enzymatic steps and every enzyme is codified by a different gene. That means polygenic inheritance, that several genes are implicated in determined the this trait and its difficult to trace since every gene has a sequence that can vary between families or human groups.

Okay so i hope this help but i think its this:

2. light (either natural sunlight or artificial light, like from a light bulb)

3. carbon dioxide (CO2)(a gas found in the air; one of the gases people and animals breathe out when they exhale)

4. water (which the plant collects through its roots)

5. nutrients and minerals (which the plant collects from the soil through its roots)

Did researching for you so I hope this helped? :)

Select the best answer that describes how lionfish are impacting biodiversity in Florida. O Lionfish are consuming large quantit
jolli1 [7]

Answer:

Lionfish are rapidly consuming many smaller fish species along the coast at depths up to 90 meters.

Explanation:

Lionfish is an invasive species that has been successfully established in the Atlantic Ocean. It is a tropical species that lives mostly in reefs and rocks that provide protection. It <u>i</u><u>nhabits waters from the coast to 50 meters deep. </u>

Because of its high densities in the Atlantic, Lionfish is a promoter of ecological, economic, socio-cultural consequences. They only have a few predators and consume a high diversity of prey items. They produce an ecological imbalance in the trophic chains of the marine ecosystem. When competing with native piscivores, they imbalance the dynamics of fish communities in coral reefs and mangroves. The <u>density of young and herbivores fishes has decreased because of their predation by the lionfish</u><u>.</u> By <u>predating on algae eating fishes</u>, they provoke a sharp increase in algae populations, which produces serious damages in the coral reefs, enhancing their mortality. The main consequences of these damages are marine biodiversity loss, water quality decrease, ecosystem recovery difficulty, and impacts on food provisioning for many other ocean species.

Think about the two words that make up the term reproductive isolation. How do you think reproductive isolation affects the evol
Hitman42 [59]

Answer:

Reproductive isolation refers to the inability of an organism or species to breed successfully with other organism or species.

It may arise from various factors such as:

  • Geographical isolation such as river, mountain, etc
  • Behavioral changes such as mating time or season, mating rituals, mating location etc.
  • Physiological differences such as change in shape of sex organs which causes lack of fit between copulatory organs.
  • Genetic differences.

Reproductive and geographical isolations between two populations (of same species) inhibit the flow of genes among them. Slowly, these isolations increase the variations in the gene pools of the two populations.

These genetic variations keep on increasing with time. In addition, as an adaptation to their surrounding or habitat the two populations would develop different behavioral and physiological changes

With time, these differences will increase up to such an extent that the two populations would not be able breed with each other. Hence, it would lead to the evolution of one or both the populations into new species.
