Answer:
Abiotic is basically a non living factor so the answer is
D. Sunlight, temperature , conductivity, dissolved oxygen.
All other options contain one biotic or living factor like algae, star fish and crabs these aren't Abiotic.
The best answer is B - Proteins.
Proteins make up enzymes, or to put it another way enzymes are made up of protein. It is enzymes that speed up the chemical reactions. Enzymes are organic catalysts, substances that speed up a (biochemical) reaction but do not take part in the reaction and remain unchanged at the end of the reaction.
In man, there are many enzymes. The majority of these are found in the digestive system where they greatly aid the process of food breakdown from complex molecules to simple molecules. Examples include salivary amylase found in saliva, which begins the gradual breaking down of starch into glucose right from the moment food is placed in the mouth and mixed with saliva. Pepsin in the stomach breaks down protein.
Answer:<u><em>When water freezes, it contracts, decreasing the water level in a lake. Water in a lake freezes from the bottom up, killing most aquatic organisms. When water in a lake freezes, it floats, providing insulation for organisms below.</em></u>
Explanation:
Answer: The product of DNA replication is DNA_, the product of transcription is RNA and the product of translation is PROTEIN
Explanation: The central dogma of molecular biology says that DNA serve as a template for its own replication by DNA polymerase, then through transcripcion process, a DNA template is read by RNA polymerase to synthetize RNA and that RNA serve as a template to synthetize proteins by ribosomes in translation process.
