18. What does an enzyme do to the activation energy?

Biology

Answer:

Enzymes allow activation energies to be lowered.

Explanation:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering the activation energy.

Proteins and carbohydrates have many functions in the body of an organism. Specific proteins and carbohydrates perform specific
WINSTONCH [101]

Answer:

Both store materials needed by the organism.

Explanation:

Proteins and carbohydrates are two biomolecules present in living organisms. They perform varying functions in the body of an organism. According to this question, a specific protein (ferritin) and carbohydrate (glycogen) is described.

Ferritin is a protein molecule containing Iron (Fe). Iron is needed by living organisms as it plays a vital role in organism's metabolism. On the other hand, glycogen is a carbohydrate molecule that is made up of glucose molecules, needed by living organisms.

Based on the description of the two biomolecules provided, they are similar in their primary functions for an organism in the sense that THEY BOTH STORE MATERIALS (glucose and iron) NEEDED BY AN ORGANISM.

Please help <br>is it currently possible to take a core sample?<br>​
Xelga [282]

Answer is YES your welcome

Explanation:

Core samples are most often taken with their long axis oriented roughly parallel to the axis of a borehole, or parallel to the gravity field for the gravity-driven tools. However it is also possible to take core samples from the wall of an existing borehole.

Explanation:

Shotgun sequencing is a method used to determine the nucleotide sequence of entire chromosomes/genomes. This sequencing method consists of obtaining random DNA fragments which are subsequently classified by bioinformatic tools that ordering them according to overlapping sequences called contigs. In the whole-genome shotgun (WGS) technique, the entire genome of an organism is sequenced, being the critical factor the depth of sequencing, which refers to the quality of the sequencing reads (e.g., a depth of 20X indicates that the genome is sequenced 20 times by a sequencing machine). For the human genome, WGS became available after the completion of the Human Genome Project (HGP), which enabled the generation of a reference sequence for the whole human genome. The steps of the WGS technique are the following:

1. Preparation of isolated chromosomes

2. The DNA is sheared into small fragments

3. The DNA fragments of about 1 kilobase (1000 base pairs) are incorporated into plasmids which are cloned to render pure samples of each DNA fragment

4. The plasmid clones are sequenced by sequencing machines

5. Bioinformatic tools finally are used to link DNA fragments by their overlapping ends
