What is the relevance of biochemistry in conservation biology?
An appreciation of biochemistry is essential to understanding a multitude of environmental factors. Take deforestation and desertfication for example... For a long time it has been thought that mere over-abundance of livestock lead to desertfication. When herds were reduced or removed, desertfication increased!
The explanation for this is apparent to one who understands biochemisty:
Animal feces and urine contribute substantial carbon and nitrogen loads to the soal. Complex organic matter with multiple hydrophylic compounds can hold moisture in the soal and can alter the microbial flora to one that promotes processes favorable to plant root development.
All ecosystems involve interactions in water, soil and air - to understand the ecology of these systems you need to understand the contributing elements.
What is the difference between AT and GC pairing?
AT pairing involves adenine on one strand pairing with thymine on the other, while GC pairing involves guanine on one strand pairing with cytosine on the other. AT pairing forms two hydrogen bonds, while GC pairing forms three hydrogen bonds. AT and GC pairing are essential for the complementary base pairing in DNA double helix structure.
What characteristics of a protein remain after it is denatured?
When a protein is denatured, its molecular shape is altered. This alteration may or may not be reversible.
What remains is the primary structure of the chain(s) of the protein, in other words the sequence of the amino acids.
The tertiary structure referers to the overall three dimensional shape will be lost
Restriction enzymes (also known as restriction endonucleases) are proteins which cut DNA up at specific sequences in the genome. For example, the commonly used restriction endonuclease EcoRI recognizes every point in DNA with the sequence GAATTC, and cuts at the point between the Guanine and Adenine. Interestingly, the recognition sequences for most restriction endonucleases are genetic palindromes, e.g., the sequence reads exactly the same backwards on the complementary strand. In the case of EcoRI, the two complementary DNA strands for the recognition sequence are: 5'--GAATTC ---3'3'--CTTAAG--5'
Can water enter the automatic transmission on a 2005 jeep rubicon during high water crossings?
Yes, water can enter the automatic transmission during high water crossings if the transmission vent is submerged or damaged. This can cause damage to the transmission components and lead to problems with shifting and overall performance. It's always best to avoid driving through water that is deep enough to submerge vital vehicle components.
In the most specific terms the system you are using when you are running for your life is the what?
Well, your muscle/skeletal system is moving your body, and your endocrine system is providing the necessary hormones (adrenaline) to help you run, your cardio-respiratory system is working VERY hard to supply the body with oxygen, and your nervous system is controlling all of this... You are using pretty much every body system except your reproduction and excretory system (unless you are crapping your pants...)
NovaNET answer Sympathetic system.......Good Luck ;)
What is the substrate for gastric juice?
The substrate is proteins, and the products are peptides.
Pepsin is a protease, i.e. an enzyme that catalyzes the breakdown of proteins. In humans, it is secreted by certain cells (called chief cells) in the lining of the stomach.
Specifically, pepsin breaks the peptide bonds linking amino acids in the chains found in proteins. Pepsin cannot break all peptide bonds, however. It is particularly efficient at hydrolyzing the bonds on the C-terminal side of tyrosine, phenylalanine, and tryptophan. It does not attack bonds involving glycine, alanine, or valine residues.
So you can think of pepsin as being like someone taking a pair of scissors to a long piece of string, and cutting in certain places. The result of peptic activity is shorter chains, called peptides.
These peptides are later further digested by other enzymes secreted by the pancreas and small intestine. The final result is free amino acids, which can be absorbed by the villi of the small intestine.

Is cellulose a polysaccharide?
Yes, cellulose is a polysaccharide. It is a complex carbohydrate made up of repeating units of glucose molecules linked together in long chains. It is the main structural component of plant cell walls.
What are examples of polyatomic ions?
There are a zillion. Simply put, a polyatomic ion is an ion with two or more atoms in it. (Polyatomic is "multi" atom.) The number "zillion" isn't specific, of course, but we might be able to use it here in the science section to make a point. The phosphate group, PO4-2, and the hydroxyl group, OH-, are just two of many, many polyatomic ions. A link can be found below to the Wikipedia article on polyatomic ions. You'll find a looong list of them there. Why not check it out?
FEME stands for "Factory, Energy, & Environment." It is an approach that integrates factory management, energy efficiency, and environmental sustainability to improve overall operational performance and reduce environmental impact. It often involves implementing energy-saving technologies, optimizing production processes, and reducing waste generation.
How much is aluminum metal worth?
The price of aluminum metal varies depending on market conditions, but it is typically around $0.80 to $1 per pound. Prices can fluctuate due to supply and demand, economic factors, and global trade dynamics.
I would expect a Van der Waals interaction between the R group in the tertiary structure of the protein and the CH2CH2CH2CH2NH3 group. This interaction occurs due to the transient dipoles created by the movement of electrons in the molecules. It helps stabilize the structure of the protein by providing additional attractive forces between the two groups.
What are 5 things which help growth of human body?
Drinking milk, getting at least 8 hours of sleep, exercise, eating fruits and vegetables, and eating a good diet.
Those things should help the growth of the human body.
It may take a while though
:)
What molecule is considered the universal monosaccharide?
A. Glucose B. Starch C. Sucrose D. Fructose E. Cellulose F. I'm not sure
glucose... the answers change like B. would be glucose or C ext. so watch.
What is the latin word for synergy?
The word synergy is said the same in Latin as it is in English. This word is said in Italian as sinergia and in Greek as synergia.
A substance that dissolves another substance?
A solute can dissolve in another substance. The substance that does the dissolving is called the solvent.
As soon as the zygote begins growing and dividing it is called what?
The zygote develops into a blastocyst as it undergoes multiple divisions. This stage occurs before implantation in the uterus.
Is carbon dioxide good for humans?
In small amounts, carbon dioxide is necessary for humans as it helps regulate pH levels in the blood and is involved in the process of breathing. However, high levels of carbon dioxide can be harmful, as it can displace oxygen in the air and cause respiratory problems.
Are there any vitamins that make the butt bigger?
There are no vitamins that directly increase butt size. However, a balanced diet that includes vitamins like vitamin C, D, and E may help improve overall muscle tone and health, which could potentially enhance the appearance of your buttocks. Regular exercise, specifically targeted glute exercises, along with a healthy diet, are the best ways to build and sculpt your butt muscles.
What are physical properties of glucose?
Glucose is a simple sugar. Glucose is one of the main products of photosynthesis. Glucose has 6 Carbon, 12 Hydrogen, and 6 Oxygen atoms. In animals and fungi, glucose is the result of the breakdown of glycogen, a process known as glycogenolysis.
What if your body produces heat constantly Where does this energy come from?
food.
The energy that makes our body warm, (aside from the Little bit of heat that comes directly from our surrounding's) comes from the sun. Plants convert the suns light using a process called photosynthesis and carbon dioxide into starches and sugars as well as releasing the oxygen that we need to oxidise the food we eat. When we eat these things we recombine them with oxygen which is an exothermic reaction (releases heat)
e. AB and C
Metabolism involves the synthesis of macromolecules, such as proteins and nucleic acids, as well as the breakdown of macromolecules to provide energy and building blocks for cellular processes. Additionally, metabolism involves the control of enzyme activity to regulate the various metabolic pathways within cells.
