Answer:
Explanation:
When you are thirsty, it's your body's way of telling you to drink some water because you are dehydrated. Just like a dehydration reaction, you've lost water. Dehydration reactions are named as such because as the polymers are linked together, a molecule of water is released. This happens because on one end of a monomer is a hydrogen atom (-H) that is just waiting to bind with a hydroxyl group (-OH) on another monomer. Hydroysis which is the reverse of dehydration work the same way.
Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails. These components of the phospholipids cause them to orientate themselves, so the phosphate head can interact with water and the fatty acid tails can't, hence forming a bilayer.
Macromolecules are large structures composed of atoms and smaller molecular structures and play important and sometimes vital roles in creating and sustaining life. It can be organized into four categories: proteins, nucleic acids, carbohydrates, and lipids.
Carbohydrates:
Found in many energy-providing foods, carbohydrates help the nervous system, muscles, and body in general function. A group of polymers, they contain nothing but carbon, hydrogen, and oxygen. Human bodies break down carbohydrates into their base components, which it then uses to fuel cells and maintain body processes. Plants use carbohydrates, particularly cellulose, to protect their cells and to grow larger. The list of carbohydrates is extensive and includes all sugars and starches.
The DNA of a human cell can be cut and rearranged by using Enzymes. To cut DNA into smaller segments, enzyme nucleases are used. They do this by taking the phsophodiester bonds through hydrolysis and catalyzing it. when these enzymes comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the molecule.
Answer:
Before the advent of modern biology, study of life and organism was in the realm of natural philosophy and was never in the club of classical sciences like physics, chemistry and engineering. Today biology is a science that studies life and living organisms.
Explanation:
A biologist can be categorized as a scientist because all the processes that supports scientific investigations are carried out in the study of biology- data collections, critical thinking, observation and collection of result for the purpose of public consumption.
On the other hand forensics is the mainly the aplication of science-mostly biology- in resolving criminal activities. It involves the collection of samples, anaylsing and presentaion of result for decison making.
The answer should be C/Currents
Gravity increases as mass increases.
Gravity decreases when distance decreases
