What are sources of carbon?Carbon is one of the most important elements for life on Earth, and it can be found in a variety of sources. Some of the most common sources of carbon include:
Fossil fuels: coal, oil, and natural gas are all made from carbon-based materials that have been buried and transformed over millions of years.Plants: Plants take in carbon dioxide from the atmosphere during photosynthesis and use it to build their tissues.Animals: Animals obtain carbon by eating plants or other animals.The ocean: The ocean contains dissolved carbon dioxide, which can be absorbed by marine organisms and transformed into calcium carbonate, a key component of shells and other structures.Soil: Carbon is stored in soil as organic matter, such as decaying plant and animal material.The atmosphere: Carbon is present in the form of carbon dioxide, methane, and other gases in the atmosphereLearn more about carbon sources, here:

What is a bacteria that is beneficial to humans and what does it do?
How will you react if I tell you that your body consists of 1 to 2.6 kg of bacteria? Shocked? Well, I can imagine your surprised face. Most people believe that bacteria are dangerous and are responsible for diseases and infections but this isn’t true. In fact the truth is, most of the bacteria are helpful in the functioning of a living body and are also capable of performing many other useful functions. These beneficial bacteria are present in huge numbers inside as well as outside our body. Well let’s check out various types of beneficial bacteria which not only help in proper functioning of our body but also contribute in many other functions in and outside the body. Some of the examples of helpful bacteria are Bifidobacterium, Rhizobium and E.coli.
Beneficial Bacteria – to Humans
Human body has millions of bacteria which participate in different functions of the body. As you know the amount of bacteria present in the body varies from 1 to 2.6 kg, this volume contains a huge number of bacteria. These bacteria can be present in all parts of the body but mostly they are found in the intestine where they help in the process of digestion. They also play a very important role in preventing bacterial infections in genital parts, like yeast infections. Some beneficial bacteria to humans are helpful in maintaining the pH of the body. Some are even involved in protecting the skin from many infections.
They are also helpful in the production of vitamin K and have an important role to play in the functioning of immune system. One of the most common bacteria which are helpful for humans is Escherichia coli. This bacteria is associated with the process of digestion. It is present in the large intestine where the maximum digestion takes place. These bacteria release enzymes which help in the process of digestion and synthesis of various vitamins and nutrients. Beneficial bacteria are also very helpful for the pregnant women. They reduce the chances of postpartum complications and also protects the baby from fungal infections.
Answer:
Probiotics are live bacteria that are good for us, that balance our good and bad intestinal bacteria, and that aid in digestion of food and help with digestive problems, such as diarrhea and bellyache. Bacteria that are examples of probiotics are Lactobacilli and Bifidobacterium.

Explanation:
Glycogen synthetase kinase 3 beta is a protein kinase that has been implicated in many types of cancer. Depending on the cell type, the gene for glycogen synthetase kinase 3 beta (GSK38) can act ether as an oncogene or as a tumor suppressor. Which of the following best predicts how GSK 98 mutations can lead to the development of cancer? A Cells with inactive GSK 38 fail to trigger apoptosis. B Cells with inactive GSK 38 fail to proceed past the G2/M checkpoint. с Cells with overactive GSK 98 are more likely to repair DNA damage. Cells with overactive GSK 38 have longer cell cycles.
Answer:
A Cells with inactive GSK 38 fail to trigger apoptosis
Explanation:
Apoptosis is defined as the process of programmed death cell. Tumor cells are capable of evading apoptosis, thereby leading to uncontrolled cell proliferation. Glycogen synthase kinase 3 (GSK-3) is a protein kinase that phosphorylates serine and threonine amino acid residues on different substrates, thus activating different signaling pathways and having different biological functions. The GSK-3-mediated phosphorylation on different substrates may lead to the activation or inactivation of apoptosis depending on the cell type. Thus, GSK-3 has a dual activity and functions as a tumor suppressor and oncoprotein.
In the example about the beaver's teeth, is it possible for just one beaver to evolve and get a favorable trait in its lifetime.

B. No because all traits are inherited and better teeth would have to come from those beavers with a trait for better teeth
C. Yes because animals control their traits.

help, please. this is for a friend to help me with.
Explanation:
I hope this helpppppppppppp
Answer:
14. To cause cancer, proto-oncogenes require 2 allele(s) to be mutated and therefore are considered recessive. The mutation results in a gain of function.
15. To cause cancer, tumor suppressor genes require 2 allele(s) to be mutated and therefore are recessive. The mutation results in a loss of function.

A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove
Answer:
Small intestine
Explanation:
Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.
However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.
Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.

Why does the body produce more urine on a cold day rather than a hot day if the same amount of
water is consumed?
Explanation:
During summer when the surrounding temperature is high, we lose water in the form of sweat, direct evaporation considerably. Hence kidneys retain water for maintaining fluidity of the blood and less urine is formed.
But during winter, the surrounding temperature will be very low. There will not be any sweating, no evaporation losses. Moreover to keep the body temperature constant, the blood capillaries in the skin get constricted and the blood pressure is increased. The result is that our body gets warmed up. In order to maintain the blood pressure normal, the excess water along with the wastes is excreted mostly in the form of urine. This is the reason for more urine out put and frequent urination under very cool conditions and in winter.
Weak hydrogen bonds between the nitrogenous base pairs hold the two strands of DNA together. Why are the strands held together by weak hydrogen bonds instead of covalent bonds
Answer:
Explanation:
Hydrogen bonding is usually occur wen interaction with hydrogen atoms occur.
Hydrogen bonds joins DNA polymers because an hydrogen atom occur on on one base which is called hydrogen bond donors and another oxygen or nitrogen atoms on the base across from it which is called hydrogen bond acceptors.
Adenine “A” a purine and Thymine “T” a pyrimidine each have a donor and one acceptor, whereas Cytosine “C” a pyrimidine has one donor and two acceptors, and Guanine “G” a purine has one acceptor and two donors.
This atoms allows for hydrogen bond between them that gives them structure of DNA molecule.
A nucleotides is hydrogen bonded to T nucleotides while C nucleotides is hydrogen bonded to G nucleotide this is called complementary base pairing.
