In the ocean near Antarctica, small crustaceans called krill eat algae and other phytoplankton. Krill are eaten by
many animals in the ocean, including blue whales, penguins, and fish such as herring.
Based on this information, which food web correctly shows the flow of energy in this ecosystem?
Answers
Answer: C
Explanation:
The arrows are suppost to be pointing up
The correct food web shows the arrows pointing down; option A.
What is a food web?A food web is an interconnected number of food chains showing how organisms depend on each other for food.
Since the krill depends on algae and phytoplankton for food, the arrows will point down.
And since other organisms like penguin and blue whales depend on the krill for food, the arrows will point down towards the krill.
Therefore, the correct food web is option A.The

Answers
You are studying two populations of dung beetles, one of which rolls their dung balls at noon, resting at night, and the other of which reverses this. These could speciate due to temporal isolation.
What about temporal isolation?When two or more species reproduce at different times, this is known as temporal isolation. For instance, the same rain forest is home to three different orchid species. Each species possesses one-day-only blooms that need to be pollinated on that day in order to produce seeds.Temporal isolation prevents interbreeding between individuals from different species due to differences in timing, even if those individuals may occupy the same geographic area.When two populations have divergent reproductive cycles or active seasons, this is known as temporal isolation. For instance, because wood frogs and leopard frogs reach sexual maturity at separate periods in the spring, they are unable to hybridize.

Choose the true statements about the diversity of Darwin's finches on the Galapagos Islands. Check all that apply.
Answers
Prior to the adaptive radiation of finches, there were no unoccupied habitats in the Galápagos Islands.
Beak shape is not an important key innovation.
Charles Darwin's Finches and the theory of evolutionThe Galapagos Islands are home to 13 of the world's only Darwin's finches, little land birds that bear his name. The fourteenth finch is the Cocos finch, which lives on the island of Cocos in Costa Rica. They aren't real finches, but rather members of the tanager family.
Natural selection, according to Charles Darwin, is a phenomenon that contributes to evolution. According to the natural selection principle, organisms create more offspring than are capable of surviving in their surroundings.
His journey to the Galapagos Islands was crucial in the formation of his theory of natural selection because he discovered a number of finch species that varied from island to island. The Galapagos Islands are an archipelago of 13 noteworthy islands.
In addition to giant tortoises, iguanas, fur seals, sea lions, sharks, and rays, they are home to 26 species of native birds, 14 of which are Darwin's finches. These finches are recognized as the vertebrates in the entire animal world that have evolved the fastest because of how quickly their look and behavior changed to adapt to this confined and quickly changing environment.

How are fishes, amphibians, nonavian reptiles, birds, and mammals important to humans? how are they important to ecosystems?
Answers
Fishes, amphibians, nonavian reptiles, birds, and mammals are crucial components of numerous ecosystems, particularly as intermediaries in numerous food chains and food webs.
Importance to humans:
Amphibians, particularly anurans, are economically advantageous because they help to decrease the amount of insects that damage crops or spread illness. Fishes and Amphibians serve as a food supply for some human communities, particularly in Southeast Asia, and hence provide provisioning services. They also present promise for new pharmaceuticals including analgesics and anti-viral medications made from skin secretions, as well as function as models in medical research. For food and clothing, humans have relied on other mammal species. Mammals were domesticated to provide a source of nourishment for the expanding human population as well as tools for hard labor and transportation.Birds help people directly by controlling insects and rodents, pollinating plants, and dispersing seeds.Importance to ecosystem:
Both reptiles and amphibians play a significant role in both terrestrial and aquatic ecosystems. Both groups function as predators and prey, and the species that live in both environments help move energy back and forth between them.The thin skin of amphibians allows them to occasionally breathe through it and allows them to absorb harmful chemicals, radiation, and infections. Because they are the first to be impacted by environmental deterioration, frogs are regarded as "indicator species."Birds help people directly by controlling insects and rodents, pollinating plants, and dispersing seeds.Mammals facilitate carbon sequestration and water body conservation by controlling the populations of other animals and protecting essential plant species.learn more about amphibians here: https://brainly.com/question/10714806

Within the mesohyl of a sponge are small rigid structures that act like an endoskeleton, providing structural support for the sponge. What are these called
Answers
Spicules are small rigid structures that act like an endoskeleton, providing structural support for the sponge within the mesohyl of a sponge
The "bricks" or structural elements of a sponge are known as spicules, and each species has its own distinct range of spicule sizes, forms, and compositions. When combined, these characteristics can be examined under a microscope to ensure correct identification. Either calcium or silica makes up spicules.
The only skeleton in soft sponges that encrust such hard surfaces as rocks is an internal gelatinous matrix called the mesohyl, which serves as an endoskeleton in the majority of sponges. The mesohyl is typically strengthened by spongin fibers, mineral spicules, or both. Spicules serve as the skeleton and support system for sponges. Additionally, they offer defense against predators.

Fructose has the formula C6H12O6. How many moles of fructose are there in 0.100 g of fructose?
Answers
Considering the definition of molar mass, there are 0.00055 moles of fructose in 0.100 grams of fructose.
Definition of molar massThe molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.
Molar mass of C₆H₁₂O₆In this case, you know the molar mass of the elements is:
C= 12 g/moleH= 1 g/moleO= 16 g/moleSo, the molar mass of the compound C₆H₁₂O₆ is calculated as:
C₆H₁₂O₆= 6×12 g/mole + 12× 1 g/mole + 6× 16 g/mole
Solving:
C₆H₁₂O₆= 180 g/mole
Moles in 0.100 grams of fructoseYou can apply the following rule of three: If by definition of molar mass 180 grams of fructose are contained in 1 mole, 0.100 grams of the compound are contained in how many moles?
[tex]amount of moles= \frac{0.100 gramsx 1 mole}{180 grams}[/tex]
amount of moles= 0.00055 moles
