Answer:

Carbon cycle is very important for the plants and animals that are divided into 4 steps and these steps are:

1.The carbon enters the atmosphere in the form of carbon dioxide.Example: respiration and combustion.

2.The carbon dioxide present in the environment is used by the plants and  plants expel oxygen after the process of photosynthesis.

3. Animals present in the environment eat the plants and pass on the carbon in the food chain. They exhale carbon dioxide into the environment.The plants and the animals die after a certain period of time.

4. The body of plants and animals is consumed by decomposes and the carbon is returned into the atmosphere in the form of carbon dioxide else fossils of plants and animals are formed which contains carbon.

Answer:

Explanation:

Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. ... After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.

Answer:

HORMONES are chemical-signaling molecules, usually small proteins or steroids, secreted by endocrine cells that act to control or regulate specific physiological processes, including growth, development, metabolism, and reproduction. For example, insulin is a protein hormone that helps to regulate the blood glucose level.

ENZYMES  which are produced by living cells, are catalysts in biochemical reactions (like digestion) and are usually complex or conjugated proteins. Each enzyme is specific for the substrate (a reactant that binds to an enzyme) it acts on. The enzyme may help in breakdown, rearrangement, or synthesis reactions.

If the object shown has a mass of 80g, what is the density?

Answers

Answer:

C. 1.23 g/ml

Explanation:

[tex] Density = \frac{Mass}{Volume} [/tex]

Mass of rock = 80g

Volume of rock = final fluid volume - initial fluid volume

Volume of rock = 265 cm³ - 200 cm³ = 65 cm³

[tex] Density = \frac{80g}{65 cm^3} [/tex]

[tex] Density = 1.23 g/cm^3 [/tex]

1 cm³ = 1 ml

Therefore, density of the object = 1.23 g/ml

A student wants to investigate the force of gravity. The student has an apple and a marble. What would be the best way for the student to use these materials? Place the apple on the floor. Roll the marble so it hits the apple. Put both objects on a desk. Push them forward at the same time. Hold both objects at the same height above the floor. Drop them at the same time. Place the marble on a desk. Place the apple next to the marble so the objects touch.

Answers

Answer:

Put both objects on a desk

Explanation:

The best way to use the materials to investigate the force of gravity would be to put both objects on a desk. The force of gravity can thus be obtained by measuring the distance between the objects as well as their masses.

According to Newton's law of universal gravitation, the force of gravity (F) between two objects is directly proportional to the product of their masses (m and M) and inversely proportional to the square of the distance (d) separating them.

Mathematically,

     F = G [tex]\frac{mM}{d^2}[/tex] where G is a constant.

Which of the following best describes the flow of energy in the Everglades food web shown below? (4 points)

Diagram for an everglades food web. The food web contains the following organisms: American alligator, egret, raccoon, carp, Key deer, insects, Southern leopard frog, mangrove, and sawgrass. Mangrove is at the bottom of the food web, with arrows pointing to Key deer and insects. Sawgrass is also at the bottom of the web, with an arrow pointing to insects. Key deer, insects and Southern leopard frog are on the next level up. The Key deer has an arrow pointing to American alligator. The insects point to egret, carp, and Southern leopard frog. The Southern leopard frog points to the American alligator and the raccoon. The egret, carp and raccoon all points upward toward the American alligator. The carp also points to the egret. The American alligator is at the top of the food web.

a
Egret → insects → mangrove → key deer → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level.

b
Mangrove → insects → carp → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level.

c
Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

d

What is a food web?

All the food networks in a single ecosystem make up a food web. Each organism in an ecosystem is a link in a number of food chains. Energy and nutrients can go along different food chains as they move through the ecosystem.

The trophic levels are divisions into which organisms in food webs are categorized. These levels can be roughly categorized as producers (first trophic level), consumers, and decomposers (last trophic level).

Only 10 percent of energy transfers to the next level. Hence, option B is correct.

Ashes (which are made of carbon), carbon dioxide gas, water vapor, heat, and light are produced when wood is burned. Since this change cannot be undone, it is a chemical change. Since oxygen and hydrogen unite to create a single product, Thus option D and E is correct.

What is chemical changes?

A chemical change is the transformation of one substance into another, the emergence of new compounds with distinct properties, or any combination of these.

It happens when two compounds mixes to create a new material (synthesis or either decomposes to form more substances).

Chemical synthesis, or, alternatively, chemical breakdown into two or more separate molecules, occurs when one material reacts with another to create a new substance.

These processes are referred to as chemical reactions, and they are typically irreversible barring additional chemical reactions.

Therefore, burning of wooden logs and formation of water is an example of chemical changes.
