Answer:

The options

a. sympatric speciation; vicariance

b. allopatric speciation; vicariance

c. sympatric speciation; dispersal

d. allopatric speciation; dispersal

The CORRECT ANSWER IS d.

d. allopatric speciation; dispersal

Explanation:

Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).

Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.

In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.

forsale [732]

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds, Three main ingredients are required for photosynthesis: water, carbon dioxide, and light. Plants use light energy from the sun to convert six water molecules (6 H2O) and six carbon dioxide molecules (6 CO2) into a molecule of glucose and six molecules of oxygen, Carbohydrates(glucose) and Oxygen is the end product.

Which level of biological classification do Mammalia and Hominidae represent, respectively?
cupoosta [38]
The answer is class and family.

<span>Taxonomic groups are used for biological classification. There are eight main taxonomic groups: domain, kingdom, phylum, class, order, family, genus and species, with the domain as the most inclusive and species as the least inclusive. If we take a look on Mammalia and Hominidae classification, we can assume that Mammalia represents class, and Hominidae represents family:</span>

<span>1. Domain: Eukarya</span>

<span>2. Kingdom: Animalia</span>

<span>3. Phylum: Chordata</span>

<span><u>4. Class: Mammalia</u></span>

<span>5. Order: Primates</span>

<span><u>6. Family: Hominidae</u></span>

<span>7. Genus: Homo</span>

<span>8. Species: Homo sapiens</span>
