When Darwin first saw finches, they were often black, brown, or olive in hue, which caused him to describe them as “drab and uninteresting little birds.” Their beaks, which differ greatly in size, shape, and color, are their most distinctive feature. Thus, option A, C, D, G, E is correct.
What are the different feature of the Darwin finches?Darwin questioned why bird beaks on different islands had different shapes. Compared to its relatives, the ground finches, so-called cactus finches have longer, more pointed beaks.
Warbler finches have beaks that are both more pointed and narrower than both. They are better able to subsist on available food thanks to these adaptations.
The plumage and body size of the birds vary, but the beaks' size and shape—which are influenced by the foods the birds prefer and their areas of specialization—are the features that stand out the most.
Therefore, Darwin notice about the different species of finches.

Where does the energy in a food web come from or originate?.
Answer:
The energy in the food web ultimately originates from the sun. Energy travels from the sun to the earth in the form of electromagnetic radiation. Autotrophs (primary producers) are able to capture this energy and convert it into sugar molecules via photosynthesis. These sugar molecules provide the energy that travels up the food chain as consumers eat other organisms.
So, the answer is: The Sun.

What is in a snooks diet. And also the habitat.
Answer:
Larval and small common snook eat mainly copepods and microcrustaceans. As common snook grow larger they eat fish, shrimp, crabs and zooplankton. This change in food habits occurs at around 1.8 inches (4.5 cm) standard length and continues throughout adulthood. Adult common snook inhabit many environments including mangrove forests, beaches, river mouths, nearshore reefs, salt marshes and sea grass meadows. Adult common snook appear to be less sensitive to cold water temperatures than larvae or small juveniles.

Relate the greenhouse effect shown in the
figure to global warming and the carbon
cycle. How do humans impact this
relationship?
The greenhouse effect is the trapping of gases in a planets lower atmosphere, causing the planet's temperature to increase over periods of time.
Global warming, or climate change, is usually referred to the human-reduced warming of the Earth.
The carbon cycle is the biogeochemical cycle where carbon is exchanged among the biosphere(the regions of the surface, atmosphere, and hydrosphere of the Earth), the pedosphere(Earth's soil mantle), geosphere(the almost spherical concentric regions of matter that make up the Earth's atmosphere), hydrosphere(the water on the Earths surface), and atmosphere(a layer of gas or gases that envelope a planet).
Humans impact this relationship by using fossil fuels daily. Fossil fuels put carbon dioxide into the atmosphere. Our use of limestone to make things such as concrete and our changing land use also impacts this relationship.
Which structure is an important site for early blood cell formation and is the first of the extraembryonic membranes to form
Yolk sac is a structure that has a short duration in intrauterine development and is an important site for early blood cell formation.
What is the yolk sac?It is the bag that houses yolk inside and that allows the embryos of certain species to feed in the initial stages of development.
Due to this structure, the embryo receives oxygen and nutrients and can discard its waste, in the case of the human being, the yolk sac fulfills the functions of the circulatory system, until the internal circulation begins to develop.
