What are the helpful microbes called?
There are different types of beneficial microbes, an example of it is nitrosomonas that converts nitrogen to be used by animals and plants. Another example is the microflora which is good microbes living in human body.
What is the primary source of energy for the human body?
The human bodies' primary source of energy is glucose. Glycogen can be called on if the body is under stress.
What is the function of allelic ladder?
An allelic ladder is a mixture of DNA fragments of known sizes that are used as a reference to estimate the size of DNA fragments in a sample by gel electrophoresis. It helps in determining the sizes of unknown DNA fragments by comparing their migration distances to those of the fragments in the allelic ladder on the gel.
Where does the term carbohydrate come from referring to the parts of the word?
The term "carbohydrate" comes from the chemical composition of these compounds, which consist of carbon, hydrogen, and oxygen molecules. The "carbo-" prefix refers to carbon, while the "-hydrate" suffix suggests the presence of water molecules in the structure.
How do you write photosynthesis in word formula?
Carbondioxide + Water ----------------> Glucose + Oxygen
What can cause the cell cycle to become uncontrolled?
Mutations in genes that control cell division, such as oncogenes or tumor suppressor genes, can lead to uncontrolled cell cycle progression. Environmental factors like radiation or chemicals can also disrupt cell cycle regulation. Additionally, viruses can integrate their DNA into the host cell's genome, affecting cell cycle control.
What vitamins help the body to use protein?
Vitamins B6, B12, and C play important roles in helping the body utilize protein. Vitamin B6 helps in the metabolism of amino acids, vitamin B12 aids in the synthesis of proteins, and vitamin C helps in the absorption of iron which is needed for protein production.
What does is mean for an organism to be anaerobic?
An anaerobic organism is one that can survive or grow in the absence of oxygen. These organisms typically utilize alternative electron acceptors, such as nitrate or sulfate, to generate energy for their metabolic processes. Anaerobic metabolism often produces byproducts such as methane or hydrogen sulfide.
What results from the action of sucrase on sucrose?
A molecule of common table sugar, sucrose, can be hydrolyzed into its two main molecular components by the enzymatic action of sucrase. Following hydrolysis, the resulting fragments are fructose and glucose.
What are the basic structural units of Dna and Rna molecules?
Answer: The basic unit of DNA and RNA is nucleic acid. Notice DNA and RNA both end in NA that is because NA stands for nucleic acid. The D in DNA stand for Deoxyribo. And the R in RNA stands for ribo. So DNA's full name is deoxyribo nucleic acid and RNA's full name is ribo nucleic acid.
How does polypeptide differ than an equal protein?
Both peptides and proteins are made up of strings of the body's basic building blocks – amino acids – and held together by peptide bonds. In basic terms, the difference is that peptides are made up of smaller chains of amino acids than proteins. ... As a general rule, a peptide contains two or more amino acids.
ATP (adenosine triphosphate) is involved in providing the energy needed for DNA replication, transcription, and repair. ATP is used as a source of energy by enzymes involved in these processes, ensuring that the DNA functions properly within the cell.

Living or occurring only in the presence of oxygen, as in certain microorganisms
Aerobics is a complex of exercises that can help you to lose overweight pounds, effectively destroy cholesterol - the main enemy of blood vessels, and improve your mood liquidating stress.
No, oxygen is not an enzyme. Oxygen is a gas that is essential for life as it is involved in the process of respiration, but it does not function as an enzyme. Enzymes are proteins that act as catalysts for chemical reactions in living organisms.
Where do calcitonin and parathyroid hormones come from?
Calcitonin is released from thyroid gland in response to hypercalemia. On the other hand, parathyroid hormone- as you guessed - is from parathyroid gland in response to low levels of blood calcium. Which will cause calcium to be released from bone into blood to compensate.
You cant make heavy water in a normal home or lab you need to have very specilized equpiment for example huge electromagnets nuetron guns which is probably worth over $100,000 , take the easy option and buy it froma chemical supplier for example Sigma Aldrich
Multiple stage cascade electrolytic isotope enrichment. However the electricity cost to power the cascade will be much higher than the cost of equipment, unless you build right next to a very large hydroelectric plant and convince them to sell electricity to you at well below wholesale.
No electromagnets or neutron guns required.
What is an example of a current research focus in chemistry?
One current research focus in chemistry is the development of sustainable materials, such as biodegradable polymers and recyclable plastics, to address environmental concerns. Researchers are also studying the chemistry of renewable energy sources, like solar cells and batteries, to improve their efficiency and accessibility.
Why does the fetus need amino acids glucose calcium and iron?
Amino acids are essential for protein synthesis, glucose provides energy for growth and development, calcium is needed for bone formation, and iron is crucial for oxygen transport in the blood. These nutrients support the fetus's overall growth and development during pregnancy.
NOPE! Or else fat people would just drink water to loose weight, instead if having to be on special diets and pharmaceuticals. Put oil in water and see what happens, they separate.
What is a false fact of amino groups?
A false fact about amino groups is that they are only found in proteins. In reality, amino groups can be found in a variety of molecules, including amino acids, amines, and neurotransmitters.
Do archaebacteria have a cell wall?
Yes, archaebacteria have a cell wall. However, the composition of their cell wall differs from that of other bacteria, as archaebacterial cell walls lack peptidoglycan. Instead, they contain unique molecules such as pseudopeptidoglycan or S-layer proteins.
No,DNA is a nucleic acid.DNA stand for Dioxyribose Nucleic Acid.
What is the geographical distribution of the ocean?
The ocean covers about 70% of the Earth's surface and is divided into five main basins: the Pacific, Atlantic, Indian, Southern, and Arctic Ocean. These oceans are interconnected, but the distribution varies with the Pacific Ocean being the largest and the Arctic Ocean being the smallest.
When a cell gets too big however what does it tend to do?
If a cell becomes too large, diffusion is too slow to provide the interior of the cell with proper nutrients. The DNA of the cell can not be copied fast enough, and the larger a cell is the less surface area the cell has.
What are the elements that make up 96 percent if the human body?
Short Answer:
The 4 atoms, O, C, H and N are about 96% of our mass, but with calcium added in, the group of 5 represents more than 97% of the body mass of the average person.
Accounting by Mass:
The mass of the human body is provided mostly by oxygen, carbon, hydrogen, nitrogen. Together these elements account for about 96% of the mass of a human.
Add in about a kilogram of calcium in the bones and body fluids and you are up to 97.4%. All of this depends on the particular person since water, our major component, can differ by 10% from one individual to another.
That said, typically the breakdown goes like this.
Oxygen: 65% of the mass
Carbon: 18% of the mass
Hydrogen: 10% of the mass
Nitrogen: 3% of the mass
Calcium: 1.4 % of the mass
Phosphorus 1.1% of the mass
With phosphorus, one has accounted for 98.5% of the mass of the typical human and that will change by a couple of tenths from person to person.
Accounting by Numbers:
Numerically we have nearly twice as many hydrogen atoms in our bodies as compared to all other elements combined. Specifically, hydrogen counts as 63% of our atoms by number, give or take a bit, but being so light it barely gets to 10% of our mass. Oxygen atoms count as 24% and carbon atoms are a mere 12% of the populations.
Together, our three basic organic building blocks account for 99% of all the atoms in the body.
Caveat:
As was said above, the water content of the human body weight varieties between 55 to 65 % from one person to the next and being the major component changes the numbers above a little for each individual.
Summary:
Almost 99% of the mass of the human body is made up of the six elements oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
Most of the last 1% is made up of five elements: potassium, sulfur, sodium, chlorine, and magnesium, but a tenth of a percent or so is made up of another dozen or so elements which include those recognized as essential to health such as iron, iodine and fluorine as well as beneficial trace elements like manganese, copper and zinc.
