Answer:

Option D is correct.

Unit rate = $75.46/ share

Explanation:

Unit rate defined as the rate are expressed as a quantity 1, such as 3 feet per second or 8 miles per hour, they are called unit rates.

Given the statement: $6,188 for 82 shares of stock.

⇒Number of share = 82

Substitute the given values we get;

Therefore, the unit rate (nearest to hundredth place) is, $75.46/ share

Answer:

The formation of new species in the Anolis lizard genus on different islands, such as in the Caribbean, can be explained through a process known as adaptive radiation. Here's how this might have occurred:

1. **Founder Effect:** An ancestral population of Anolis lizards could have initially colonized an island. These individuals would represent only a subset of the genetic diversity of the main population on the mainland.

2. **Island Isolation:** Islands are isolated environments, which means that the colonizing population would be relatively isolated from the mainland. This isolation can lead to unique evolutionary pressures and opportunities.

3. **Adaptive Radiation:** With time, the isolated population would adapt to the specific environmental conditions of the island. This might include changes in diet, behavior, morphology, and other traits to better exploit the island's resources and ecological niches.

4. **Divergent Evolution:** Different populations of Anolis lizards on various islands would undergo divergent evolution. Each population would adapt to its specific island environment, leading to the development of distinct traits and characteristics.

5. **Reproductive Isolation:** Over many generations, these isolated populations could become reproductively isolated from each other. This means they can no longer interbreed to produce fertile offspring.

6. **Speciation:** When reproductive isolation occurs, and genetic differences accumulate between populations, new species can form. This is the essence of speciation. Each island's population may evolve into a unique species with its own set of characteristics.

7. **Ecological Niches:** Different islands offer different ecological niches and opportunities. Some Anolis species might become tree-dwelling, while others may adapt to life on the ground or in different vegetation types. This diversification allows them to exploit various resources and minimize competition within the island's ecosystem.

8. **Natural Selection:** Throughout this process, natural selection would act on the traits that enhance an individual's fitness in their specific island environment. This would drive the evolution of specialized features and behaviors.

Overall, the combination of isolation, adaptation to local conditions, and the accumulation of genetic differences over time can lead to the formation of multiple new species from a common ancestor, as seen in the Anolis lizards and many other island-dwelling organisms. This phenomenon is a classic example of evolutionary biology and demonstrates how biodiversity can arise in isolated environments.

Final answer:

Allopatric speciation could have led to the formation of new species from the ancestral anoles on different islands. This concept involves physical isolation, like that created by an island environment, followed by independent evolution due to environmental factors, genetic drift, and natural selection, which result in new species.

Explanation:

The process you're asking about can be explained by a concept called speciation -- more specifically, a type called allopatric speciation. This occurs when a population of a species is subdivided, often by physical barriers like water or mountains, and the smaller groups are isolated from each other. Over time, environmental differences, natural selection, or genetic drift, cause the independent evolution of the isolated populations, leading to the development of new species.

In the context of the ancestral anoles on different islands, this could have occurred if the ancestral population was spread across different islands – effectively isolating each group due to the surrounding water. Each island could possess unique environments with different predation pressures, food sources, climates, etc.

Answer:

The correct answer will be option-D

Explanation:

The studies done by the scientist led to the conclusion that the doges were evolved from the wolves,

The interaction of the wolves with humans became symbiotic around 10000-15000 years ago when the wolves in search of food changed themselves and adapted to survive with humans.

The studies on the genes of Dog shows that the gene responsible to digest carbohydrate called amylase starting duplicating in Wolves allowing them to digest carbohydrate cereals offered by humans. Their pancreatic enzymes also got modified to digest the carbohydrate-protein rich cereals.

Thus, option-D is the correct answer.

Answer:

Protein (the apoenzyme) and active site (cofactor) is the correct answer.

Explanation:

The two components are often found as part of an enzyme are

Protein (the apoenzyme)

• proteins increase the rate of reaction that takes place within the living organism.

• proteins consist of one or more chains of amino acids that make macromolecules.

• They perform important functions within the organism such as proteins function is to catalyze the reactions that are necessary to our metabolism.

Active site (cofactor)

• Active site:is the site where the enzyme binds with the substrate to initiates the reaction.

Answer:

In terms of ecology a niche can be defined as role or function an organisms play within the ecosystem. A niche represent the interaction of an organism with the living and non living components of the ecosystem. It is represented by predator-prey relationships, parasitic and mutualistic properties and other functions. The two species cannot occupy the same niche for an extended period of time, this can be explained by competitive exclusion principle. According to this principle, no two species can have the same ecological niche. The two or more species competing for the same resource in an ecosystem the one species having more favorable adaptations will be able to thrive resources better than others. Therefore, this  will result in the decrease in abundance, migration and extinction of weak and less competitive species.
