To answer the question, crust and mantle come under Compositional layers. The mesosphere and asthenosphere come under the Physical layers of Earth.
The Compositional layers of the Earth include the Crust, Mantle, and Core. The crust is the outermost layer of the Earth, where we currently live in. The mantle is the layer below the crust, and, by volume, the largest chemical layer as well. The Core is the innermost layer of the Earth, discovered by scientists in 1906.
The Physical layers of Earth include Lithosphere, Asthenosphere, Mesosphere, Outer core, and Inner core. The lithosphere defines as the outermost physical layer of Earth, which is broken into segments called plates. The asthenosphere is the layer residing below the lithosphere, has multiple plates, and is considered unbroken, unlike the lithosphere. The outer core is the only layer of Earth consisting of only liquid entirely, whereas the Inner core exists within the liquid outer core.

in coelomate animals, what type of tissue surrounds the digestive tube? What function does this type of tissue usually serve in other locations in the body?
The coelom is found between the intestinal canal and the body wall, lined with mesodermal epithelium. Coelom can absorb shock or provide a hydrostatic skeleton.
Coelomic fluid function of a hydrostatic skeleton, which helps for locomotion of soft-bodied animals and provide body a distinct shape. Contracting muscles can push against the coelomic fluid because of the fluid pressure.
In coelomate, the tissue that lines the inner side of the body cavity come from the same germ layer as the tissue lining from the outer side of the body cavity. Hence, The digestive tract of a coelomate functions as a coelom.

Explain how active transport works in a cell
Answer:
substances move against the concentration gradient, from an area of low concentration to an area of high concentration
Explanation:
Answer: Active transport is the movement of a substance across a cell membrane against its concentration gradient; From a low to a high concentration.
Explanation:
There are two types of active transport:
1) Primary Active Transport - Primary active transport, also called direct active transport, directly uses energy to transport molecules across a membrane. Most of the enzymes that perform this type of transport are transmembrane ATPases. A primary ATPase universal to all life is the sodium-potassium pump, which helps to maintain the cell potential. Other sources of energy for Primary active transport are redox energy and photon energy (light). An example of primary active transport using Redox energy is the mitochondrial electron transport chain that uses the reduction energy of NADH to move protons across the inner mitochondrial membrane against their concentration gradient. An example of primary active transport using light energy are the proteins involved in photosynthesis that use the energy of photons to create a proton gradient across the thylakoid membrane and also to create reduction power in the form of NADPH.
Secondary Active Transport - In secondary active transport or co-transport, energy is used to transport molecules across a membrane; however, in contrast to primary active transport, there is no direct coupling of ATP; instead, the electrochemical potential difference created by pumping ions out of the cell is used. The two main forms of this are antiport and symport.
What name is given to animal cells with the capacity to differentiate into a specialised cell?
Answer: Stem cells I hope this is helpful to you mark me brainlist if correct then no if wrong
Explanation:
Stem cells are the cells that have an ability to become various types of cells. They are present both during embryonic development (embryonic stem cells) and in the adult body (adult stem cells). Human ES cells differentiating into neuronsStem cells are simple, unspecialised cells found in animals and plants that have the ability to divide to form cells of the same type. They can also differentiate into a variety of specialised cells. Stem cells can be harvested from embryonic umbilical cord or adult bone marrow..A cell capable of differentiating into any type of cell is known as "totipotent". For mammals, totipotent includes the zygote and products of the first few cell divisions. There are also certain types of cells that can differentiate into many types of cells.

In each ecosystem, there are many feeding relationships. A food chain represents a flow of energy through an ecosystem, and always begins with an organism called a producer, which is able to trap light energy and convert it to chemical energy. An organism of this type is eaten by a herbivore, which is a kind of consumer that feeds only on plant material. This type of organism is, in turn, eaten by a carnivore (an organism that consumes other animals).

3. List the main phases of mitosis in order from start to finish. *
The main phases of mitosis in order from start to finish are as follows:
ProphasePrometaphaseMetaphaseAnaphaseTelophase.What is Mitosis?Mitosis may be defined as a type of cell division through which a parental cell is successfully divided into two daughter cells. These daughter cells are genetically identical to the parental cells and generally diploid in nature.
Prophase is the longest phase of karyokinesis. In this phase, the nuclear membrane and nucleolus disappear. In metaphase, the chromosomes are usually lined up in one plane by attaching to the spindle through the centromere.
Anaphase is the smallest phase of mitotic cell division. In this phase, the centromere splits, and chromosomes move to opposite poles. In telophase, the two sets of daughter chromosomes reached opposite poles and are converted into chromatin thread.
Therefore, the main phases of mitosis order from start to finish are well described above.

Do the tissues lining the gastrovascular cavity in Cnidarians differ at any point in the cavity?
All cnidarians have two tissue layers. The outer layer is called the epidermis, whereas the inner layer is called the gastrodermis and lines the digestive cavity. Between these two layers is a non-living, jelly-like mesoglea
Cnidarias have an internal sac for digestion which is called the gastrovascular cavity. The gastrovascular cavity has only one opening, a mouth, through which the animal takes in food and releases waste. Tentacles radiate outward from the rim of the mouth.
The body wall of a cnidarian consists of three layers, an outer layer known as the epidermis, a middle layer called the mesoglea, and an inner layer referred to as the gastrodermis. The epidermis contains a collection of different types of cells. These include epitheliomuscular cells which contract and enable movement, interstitial cells that give rise to many other cell types such as egg and sperm, cnidocytes which are specialized cells unique to cnidarians which in some cnidarians contain stinging structures, mucus-secreting cells which glandular cells that secrete mucus, and receptor and nerve cells which collect and transmit sensory information.
The inner layer, the endoderm , has cells that produce digestive enzymes and break up food particles. The jellylike material between the two layers is called the mesoglea. All of these body layers surround a central cavity called the gastrovascular cavity, which extends into the hollow tentacles.

The Atlantic puffin feeds on several species of Atlantic fish. A population of puffins living on Matinucus Rock was found to feed on the types of fish shown in the graph below. The beaks of this group of puffin are shaped to grasp Species A particularly well. Predict what would happen to the puffins’ beaks if another predator enters the area that is better at preying on Species A. Explain your reasoning based on what you know regarding genetic adaptations.
The number of Atlantic puffins that have adapted to species A will decrease as competition for species A increases. After several generations, the puffins that eat species B and C will be formed.
What is adaptation?
Adaptation is the process of changing in response to a changing environment. An example is seen in puffins. The puffin that eats species A has a different beak. When another predator enters who preys upon species A, then competition will increase. As a result, species A's consumption of puffin will decrease.
Those puffins that eat species B and C will survive. They will reproduce and produce more offspring. The number of puffins with beaks in Species B and C will increase over time.
Hence, after many generations, puffins of species B and C will increase.
