Answer:
Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon, but that need is also entwined with one of the most serious problems facing us today: global climate change.

Carbon is both the foundation of all life on Earth, and the source of the majority of energy consumed by human civilization. [Photographs ©2007 MorBCN (top) and ©2009 sarahluv (lower).]
Forged in the heart of aging stars, carbon is the fourth most abundant element in the Universe. Most of Earth’s carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels.
Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs. Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth.
Draft diagram of the carbon cycle.
This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year. White numbers indicate stored carbon. (Diagram adapted from U.S. DOE, Biological and Environmental Research Information System.)
Over the long term, the carbon cycle seems to maintain a balance that prevents all of Earth’s carbon from entering the atmosphere (as is the case on Venus) or from being stored entirely in rocks. This balance helps keep Earth’s temperature relatively stable, like a thermostat.
This thermostat works over a few hundred thousand years, as part of the slow carbon cycle. This means that for shorter time periods—tens to a hundred thousand years—the temperature of Earth can vary. And, in fact, Earth swings between ice ages and warmer interglacial periods on these time scales. Parts of the carbon cycle may even amplify these short-term temperature changes.

The global carbon cycle model describes the evolution of carbon mass in the mantle (Cm), the combined reservoir of ocean and atmosphere (Co+a), the continental crust (Cc), the ocean crust and floor (Cf), the kerogen (Cker), and the biosphere (Cbio).
What are the steps of carbon cycle?Carbon on the dynamic planet can move from one of these realms to another as part of the carbon cycle.
Carbon is transferred from the atmosphere to plants.Carbon is transferred from plants to animals.Carbon is transferred from plants and animals to soils.Carbon is transferred from living things to the atmosphere.When fossil fuels are burned, carbon is released into the atmosphere.Carbon is transferred from the atmosphere to the oceans.Thus, above-mentioned are the steps involved in a carbon cycle.

How do i write a good hypothesis
Answer:
use "if...then...because"
Explanation:
a good way to write a hypothesis is using "if, then, because" statements because it fully explains your idea. you also need to make sure that your hypothesis is testable and realistic.
example/
Jimothy is testing if jazz music effects bee honey production. he writes this statement:
If jazz is played near a bee hive while producing honey, then the bees will produce more honey because the smooth music will raise their dopamine levels so that they become happier and therefore faster and more productive.
Answer:
I will write some tips in my explanation!
Explanation:
After formulating wh questions, it's time to form a hypothesis or an educated guess, but how do we do this?
First, you must gather the knowledge you already know; ad back it up with something that has happened like a study, article, etc
Example: It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe.
This will be the base of your hypothesis, and from here, just add the knowledge of which you know that can make up a well supported hypothesis, which you will then test.
Example:
It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe. Because distilled water is free of impurities, we can say that it cannot conduct electricity, but if we add salt to distilled water, the water will then be able to conduct electricity because...

Explanation:
Question 1: One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic information flows between those types of molecules. Include the results of the processes of transcription and translation? ( Will Mark Brainliest if answered correctly. Do Not Repost Someone Else's Answer that is already on Brainly or any other websites please).
Answer:
Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
Answer:
DNA is the code that stores all our genetic information. When making a protein, DNA has to go through transcription and then translation. In transcription, an the genetic code of DNA is copied to mRNA, with the aid of an RNA polymerase protein which attaches single RNA units to the mRNA strand as the RNA polymerase moves on the DNA. Note that instead the letter T, RNA contains U. This occurs in the nucleus. The mRNA travels to the cytoplasm to a ribosome. The RNA also trims itself, removing parts that it does not need, and keeping parts for translation. The ribsomes use tRNA attached to amino acids to assemble the protein chain and translate the mRNA into proteins. As the amino acid chain, or polypeptide forms, a protein comes to be. However, there may be mutations, resulting from translation or transcription and sometimes these mutations may cause harmful affects.
Mutations are not always negative. Explain why this statement is true. Provide two reasons using examples to support your answer.

Applying the systems thinking techniques, outline the practical steps that can be taken to address drought
Some practical steps to address drought may include the implementation of efficient water usage techniques, the protection of vegetation, and the use of methods to retain moisture in the soil.
What is a drought?A drought is classified as the shortage or absence of water for a prolonged period of time in a region. These can be caused by a prolonged lack of rainfall.Other factors include poor water management and lack of vegetation.Methods to avoid droughts.The planting and protection of vegetation, primarily those adapted to dry environments, is important in preventing drought.Furthermore, the correct implementation of efficient water usage techniques can aid in preventing drought by limiting the amount of water that is wasted. Lastly, the use of mulch and other water retainers can be an effective method in keeping the soil moist and aids in the previous two methods.Therefore, we can confirm that the most effective ways to avoid droughts are to practice efficient water use so as to not waste water, to plant and protect vegetation, and to use mulch and other moisture-retaining methods to keep the soil from drying.

A. Females only have one X chromosome .
B. Males only have one X chromosome .
C. Males only carry recessive alleles .
D. Females only carry dominant alleles .

They have unique combinations of chromosomes.
What are gametes?
In organisms that reproduce sexually, a gamete is a haploid cell that unites with another haploid cell during fertilization Gametes, commonly known as sex cells, are an organism's reproductive cells.
A female is any individual that generates the bigger kind of gamete—called an ovum—and a male creates the smaller type—called a sperm—in species that produce two morphologically distinct forms of gametes, and in which each individual produces only one type.
The flagellum, a tail-shaped feature that enables the cell to propel and move, is what makes sperm cells, or spermatozoa, tiny and motile. On the other hand, each egg cell or ovum is sizable and non-motile.
Therefore, They have unique combinations of chromosomes.
