Algae->mosquito larva->dragonfly->fish->man
Answer:
Secondary consumer/small carnivore
Explanation:
The fish is eaten by the top of the food chain/tertiary consumer (human) and eats primary consumers/herbivore (dragonfly), which means it is the secondary consumer on the food chain.
cell theory establishes which of the following conclusions about cells?
A) all cells have the same size and shape
B) all cells form by free-cell formation
C) all cells are produced by other living cells
D) all cells have a cell wall
Answer:
C) all cells are produced by other living cells
Explanation:
Cell theory establishes the conclusion that " all cells are produced by other living cells". According to cell theory all the living cells are generated from pre- existing cells. Thus, option C is correct.
What is cell theory?Cell theory is a scientific theory given in nineteenth century and according to cell theory " cell is the structural and fundamental unit of life" and " every living cell is made up of pre existing cell".
The cells in multicellular organisms function differently from those in single-celled organism. A unicellular depends upon only one cell for all functions occurred in body. On the other hand a multicellular organism has cells specialized to perform several body functions that combinedly support the organism.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of levour is at the orgneele level on the other hand in multicellular the division of lavour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,Cell theory establishes the conclusion that " all cells are produced by other living cells". According to cell theory all the living cells are generated from pre- existing cells. Thus, option C is correct.

Which type of deposition creates sandbars? glacial river wave wind
Answer:
C / Waves
Explanation:
I took on exam got 100%
The type of deposition that creates sandbars is waves. Waves build sandbars far from shore, until they rise above the water's surface
What is sandbars?A sandbar or offshore Bar is submerged or partly exposed ridge of sand or coarse sediment that is built by waves offshore from a beach.
Deposition that creates sandbarsThe type of deposition that creates sandbars is waves.
As waves break, this pulls material from the shoreline, migrating further into the ocean. During heavy storms, large waves can build sandbars far from shore, until they rise above the water's surface.Thus, the type of deposition that creates sandbars is waves. Waves build sandbars far from shore, until they rise above the water's surface.

To which skeletal system do the carpals belong?
spongy skeleton
compact skeleton
axial skeleton
appendicular skeleton
Answer:
Appendicular skeleton
Explanation:
The carpals are bones that make up part of the hand, so the Appendicular system would be an appropriate answer. The Appendicular system got its name because it is the appendages of the axial skeleton. Your hand (as well as your arms , legs, pelvic girdle, feet,etc.) is considered your appendage so it would make sense for the bones that allow your wrist to move and rotate are considered it as well.
Answer:
appendicular skeleton
Explanation:
The carpals are bones that make up part of the hand.The appendicular skeleton is the portion of the skeleton of vertebrates consisting of the bones that support the appendages. The appendicular skeleton includes the skeletal elements within the limbs, as well as supporting shoulder girdle pectoral and pelvic girdle.

Label C
Label D
Label E
Answer:
Label A - G1 (growth phase)
Label B - S phase (DNA synthesis)
Label C - G2 phase (Growth and preparation for mitosis)
Label D - M phase (Mitosis - cell division)
Label E - Interphase
Explanation:
Label A refers G1 phase - In this phase metabolic changes occurs in the cell and cell get prepare for cell division. The cell grow in size only and moves into the S phase.
Label B refers S phase - In this phase DNA synthesis occurs in which genetic material replicates and form two sister chromatids in each chromosome.
Label C refers G2 phase - All the metabolic changes occurred prepare for mitosis and cytokinesis.
Label D refers M phase - In this phase, Mitosis occurs in which nuclear division and cell division (cytokinesis) takes place.
Label E refers to interphase - All the stages from G1 to G2 phases come under the interphase of cell division.
Hence, the correct answers are:
Label A - G1 (growth phase)
Label B - S phase (DNA synthesis)
Label C - G2 phase (Growth and preparation for mitosis)
Label D - M phase (Mitosis - cell division)
Label E - Interphase

Do you think killing lionfish is ethical? Why or why not?
Answer:
Well I don't like killing things but lionfish are technically taking over the ocean since they are traveling everywhere and a hurricane caused six fish from an aquarium to accidentally get swept out into the Atlantic Ocean. Female lionfish produce thousands of eggs at a time, which has allowed their population to increase rapidly in the Atlantic. There’s no firm estimate of the number of lionfish in the Atlantic Ocean right now. However, it might be as many as 375 to 1,000 lionfish per acre of the ocean. These fish have predators such as sharks and scorpionfish in their natural habitat. However, they don’t have many natural predators in the Atlantic Ocean, where the typical predatory animals don’t seem to recognize lionfish as food, so it probably is ethical.

A) a coastal glacier
B) water cutting the rocks
C) wind blowing in circles
D) earthquakes along the shore
Answer:
D) earthquakes along the shore
Explanation:
Movement of tectonic plates are responsible for reshaping the surface of our planet and it is contributed by earthquake sometime.
High richter scale of Earthquake allow tectonic plates to slide over each other or collide with each other of Earth's crust within a geologically period of time and causes the rising or sinking of the land.
As the image shows uplifting of land and sinking land in picture B, the action is performed by earthquakes along the shore.
Hence, the correct option is D) earthquakes along the shore.
