Which statement describes the epiphyseal plate? It is where flat bones are actively growing. It is where old bone cells are being remodeled. It is where cartilage cells are being turned into bone cells. It is where the bones in a baby's skull are growing together.
Answer:
The correct answer is - It is where cartilage cells are being turned into bone cells.
Explanation:
The epiphyseal plate is a plate of cartilage that is found at the end of each long bone, is a location for the longitudinal growth of the bones that are responsible for the height or long bone growth of an individual.
It is the site that is responsible for the formation of the cartilage bones by the process of proliferation of cells and hypertrophy of the cell which is then turned into the bones. This change takes place due to calcification, degradation, and replacement by osseous tissues.
Answer: c.) It is where cartilage cells are being turned into bone cells.
Explanation: The epiphyseal plate is also known as the growth plate. This is the site of bone elongation, where cartilage cells are being converted to bone cells
what is the difference between redshift and blueshift?
Answer:
Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion. Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow.

Carbon credits are used to a. rehabilitate tropical rainforests b. reduce the emission of volatile organic compounds (VOC's) c. regulate how much carbon dioxide a country can emit d. coordinate carbon sequestration activities
Answer:
C. Regulate how much carbon dioxide a country can emit
Carbon credits regulate the maximum quantity of carbon dioxide that a country may emit. Thus, C is the best choice.
How do carbon credits work?A marketable certificate or permit known as a "carbon credit" attests to the authorization of a specific amount of carbon dioxide emissions or the equal amount of another greenhouse gas.
Carbon credits are also called as the carbon offsets, which are licenses that allow the owner to emit a particular quantity of carbon dioxide or other greenhouse gases where the Carbon dioxide emissions or the some another greenhouse gas are allowed under one credit. The carbon credit is a part of the so-called cap-and-trade system.
A few typical examples of initiatives are garbage management, the development of renewable energy, the use of farming techniques that store carbon, and reforestation.
Therefore, the correct option is C.

A. The sun heats the air at the equator, followed by hot air rising and moisture condensing
B. Air moves towards the poles as it cools
C. The dry air moves back to the equator, picking up a lot of moisture on the way
D. The air sinks around 30° latitude and is very dry.
Answer:
B. Air moves towards the poles as it cools
Explanation:
The image represent convection cell or Hadley cell is a natural phenomenon in the atmosphere that occur due to difference in the density within a body of liquid or gas. These differences in density causes rise and fall in currents.
The process in step A refers to when hot air moves up and in the step B, the hot air encounters a cold surface, it direct exchange the heat with cold surface and the air cools down and move towards the poles.
Hence, the correct answer is "B. Air moves towards the poles as it cools".

Which part of the carbon cycle occurs when plants, trees, or fossil fuels are burned?
A. Transpiration B. Oxidation C. Photosynthesis D. Combustion
Answer:
Combustion.
Explanation:
It's just as it sounds, combustion is the process of burning something. In the carbon cycle, combustion occurs whenever any organic living or non-living thing is burned in the proximity of oxygen, afterwards producing carbon dioxide.
Combustion is the part of the carbon cycle which occurs when plants, trees, or fossil fuels are burned. Thus, the correct option is D.
What is Combustion?Combustion or burning is a high-temperature exothermic redox chemical reaction which occurs between a fuel and an oxidant. The oxidant is usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. This is one of the major reasons of pollution.
Three main types of combustion include rapid combustion, spontaneous combustion, and explosive combustion.
Therefore, the correct option is D.

B. by shivering, which is in response to an external stimulus
C. by moving into the sun, which is in response to an internal stimulus
D. by moving into the sun, which is in response to an external stimulus
Answer:
Your answer is D). Like most cold-blooded animals, geckos' bodies are unable to maintain a homeostatic body temperature on their own, therefore they must bask in the sun in order to increase their body heat, and hide in the shade when it's too hot.

Which type of communication occurs when the cells are touching? *
Answer:
Synaptic Signaling
Explanation:
In synaptic signaling, a nerve cell produces a neurotransmitter that diffuses across a synapse to a single cell that is almost touching the sender. The neurotransmitter stimulates the target cell. The transmission of a signal through the nervous system can also be considered an example of long-distance signaling.
Ecosystems Unit Test 8 of 8 Items Item 8 Discuss an ecosystem in which there is a producer, a consumer, a secondary consumer, and a decomposer. Name the ecosystem and specific organisms for a producer, consumer, secondary consumer, and decomposer
Answer:
The ecosystem, in this case, is a forest. The producers are plants. The deer, who eats the plants, is the consumer. The wolf, who eats the deer, is the secondary consumer, and earthworms are the decomposers.
Explanation:
An ecosystem is a group of beings that are in a certain area where they interact with each other and with their surroundings. In this case, we describe a trophic level with beings that are in the forest.
Producers are beings that produce their food, like plants.Consumers or primary consumers are animals that eat producers. They are herbivores.Secondary consumers eat primary consumers. They can be omnivores, or like in this case, carnivores.Decomposers are bacterias, mushrooms, or earthworms. They act on all levels breaking down the rest of the animals and plants, obtaining nutrients to nourish the soil, and start the cycle again.Why are plants in the alpine biome typically low growing?
A) They have access to nutrient-rich soil.
B) They have limited access to sunlight.

A component of a circuit changes, as shown below. How would this change affect the electric circuit? A switch is closed, so the circuit would be incomplete and broken and the lights in the circuit would not shine. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. A switch is opened, so the circuit would be incomplete and broken and the lights in the circuit would not shine. A switch is opened, so the circuit would be complete and unbroken and the lights in the circuit would shine. Mark this and return Save and Exit
Answer:
A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.
Explanation:
The image shows an open switch to a closed switch.
A closed switch represents a complete circuit, and an open switch represents an incomplete circuit. The lights would shine and the circuit would be complete because the switch is now closed.
The change affects the electric circuit as A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. The correct option is B.
What is an electric circuit?When an electric charge builds up inside of an object, it disperses across its surface and stays there until it can be discharged by an electrical current or electrical discharge; this is known as "static electricity."
From an open switch to a closed switch is shown in the image. An incomplete circuit is represented by an open switch, and a complete circuit is by a closed switch. The switch is now closed, so the lights would turn on and the circuit would be complete.
Therefore, the correct option is B. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.
