What hard covering on the outside of some animals bodies
saveliy_v [14]
The word you're looking for is Exoskeleton. The outer covering is called an EXOSKELETON which is a hard covering on the outside of the body that provides both support and protection. The exoskeleton is made of CHITIN. Some exoskeletons are leathery like caterpillars, and some are tough and hard like ticks and crabs.

Did you write several paragraphs describing the full carbon cycle in detail? Did you discuss all
Nikitich [7]
<h2>Answer 1:</h2>

yes, I have discussed the carbon cycle and all their components.

<h3>Explanation:</h3>

Carbon is an element. It is part of oceans, air, rocks, soil, and all living things. Carbon doesn’t stay in one place. carbon moves through many steps like atmosphere to plants, plants to animals, plant, and animals to the ground, living things to the atmosphere, fossil fuel to the atmosphere, and atmosphere to the ocean. Carbon moves through our planet over longer timescales as well.

<h3>Answer 2:</h3>

Carbon molecule is exchanged between organisms and atmosphere as carbon dioxide. Carbon dioxide from the atmosphere is taken up by photosynthetic organisms e.g. plants and used to make organic compounds, after the production of the organic molecule the carbon is released in the atmosphere as carbon dioxide.

<h3>Answer 3:</h3>

Plants reform the carbon into climatic carbon dioxide into carbon-containing organic compounds, such as sugars, fats, and proteins. Plants take in carbon dioxide by minute openings into their leaves, called stomata. They connect atmospheric carbon with water and produce organic compounds, utilizing energy trapped from sunlight in a method called photosynthesis. The by-product of photosynthesis is oxygen, which plants discharge into the atmosphere by the stomata.

<h3>Answer 4:</h3>

yes I have discussed how carbon enters and leaves each of the four spheres in what forms.

<h3>Explanation:</h3>

The primary carbon storage pools are the oceans and marine sediments, fossil fuels and shale deposits, terrestrial plants and soils, and the atmosphere. The global carbon cycle is characterized by large exchanges of carbon between Earth and its atmosphere. Photosynthesis and ocean uptake processes remove CO 2 from the atmospheric carbon pool, whereas CO 2 is returned to the environment by biological respiration, deforestation and land clearing, forest fires, and fossil fuel combustion associated with human activities. An organism is alive, it acts as a "carbon sink," or as storage for carbon atoms because so many carbon atoms are being used to build the organism's skin, bark, toenails or leaves.

<h3>Answer 5:</h3>

Initial carbon storage supplies are the oceans and marine sediments, fossil fuels and shale sediments, earthly plants and soils. The global carbon cycle is recognized by high exchanges of carbon between Earth and its climate. Photosynthesis and sea uptake methods eliminate Carbon dioxide of the airy carbon lag, whereas Carbon dioxide is released to the environment by respiration, deforestation, and land clearing, forest fires, and fossil fuel flaming connected with human actions. Alive organisms work as a "carbon pan," or as an area for carbon atoms because numerous carbon atoms are being used to make the organism's surface, bark, toenails or leaves.

<h3>Answer 6:</h3>

The original carbon cycle is the biogeochemical cycle by which carbon does a swap among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the central part of biological compounds as well as the main component of many minerals e.g. limestone. Forward by the nitrogen cycle and the water cycle, the carbon cycle includes a series of issues that are essential to progress Earth able of supporting life. It describes the flux of carbon as it is collected and reused completely the biosphere, as well as long-term roasting of carbon sequestration to and discharge of carbon sinks. while the carbon cycle model is a description of the action of carbon from problems to sinks by chemical and physical transfers. The carbon cycle activity allows students to see the effect of fossil fuel firing on the carbon cycle.

Why does the sodium potassium pump require ATP?
SpyIntel [72]

Answer:

The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.
