The discovery of DNA, as well as understanding of its functioning and structure, may well be the most essential findings of the last century.
The impact of the discovery of DNA on medical and scientific advancement has been huge, whether it involves the manufacturing and creation of drugs to cure the deadly diseases or to identify the genes, which stimulate several of the diseases.
The understanding of DNA and its structural composition has led to the discovery of various technologies that helps in the fields like genetic testing, identifying viruses, crime investigation, production of genetically modified organisms, and various others.
Answer:
2-Water helps maintain body temperature.
3-Diuretics like alcohol and some medications can cause the body to lose water.
Explanation:
Dehydration occurs when the amount of what loss is more than the amount taken. And we lose water in many ways therefore taking water on a regular basis is important to replace the fluids lost and keep the body functioning.
Water Maintains the Body Temperature
During high temperature, the body cools itself naturally by sweating and by sweating a large amount of water is lost. So when enough water is not taken, there will be less production of sweating thereby causing the body's temperature to rise.
Alcohol Causes Water Loss
Taking excess alcohol can result to dehydration because the hormone called anti-diuretic (while alcohol is diuretic) is used to reabsorb water by the body and alcohol in the body depletes the production of this hormone. The body loses more water than normal with a reduced amount of anti-diuretic in the body. Excessive intake of alcohol can also cause vomiting, which depletes the body of fluids and can cause further dehydration.
Answer:
Two hormones are involved in regulating homeostasis, and they are insulin and glucagon. Hope this helps.
Answer:
A. Replication
: Nucleus
B. Transcription
: Nucleus
C. Translation: Ribosomes
Explanation:
Replication is the process of making new DNA strands by using the existing DNA strands as a template. The main enzyme of DNA replication is DNA polymerase that makes DNA strands by the addition of deoxyribonucleotides to the primer in 5' to 3' direction. The process of DNA replication occurs in the nucleus.
Transcription is the process of synthesis of RNA strands using the DNA template strand. The process is catalyzed by RNA polymerase and occurs in the nucleus of eukaryotic cells. The primary transcript formed by transcription is modified by splicing, the addition of poly-A tails and 5' cap and the resultant mature mRNA leaves the nucleus to enter the cytosol.
The mRNA joins ribosomes present in the cytosol to begin the process of translation. The translation is the process of making proteins using the nucleotide sequence of mRNA as a template. The process occurs on ribosomes.
