Answer:
Dehydration
Explanation:
Dehydration is the condition of the body which involves the loss of body fluid compared to the amount of water the body gets. Water is an important constituent of the human body making up to about two-third of the body. The normal body metabolism is affected when the amount of water in the body drops below the required level of water necessary for optimal functioning of the body.
Athletes usually suffer from dehydration, most especially long distance runners, as they tend to lose a lot of body fluid through sweating while the body tries to regulate the body temperature during the race. When the body is dehydrated, the heart works harder to pump blood to various parts of the body leading to loss of strength of the muscles.
Common signs a dehydrated person shows include feeling tired and lightheaded, loss of body weight etc.
Answer:
True.
Explanation:
DNA's replication is the process where each daughter cell receives the same copy of the DNA. During the synthesis phase of the cell cycle replication of DNA occurs. While increasing speed of replication the DNA molecule is opened at several locations, and creating multiple replication bubbles.
Replication bubbles opened DNA strands at several locations where DNA are complementary to each other, such as one strand of DNA contains a nucleotides sequence of TCAGTA will have a complementary another strand with the sequence AGTCAT.
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein.
because they have have negligible mass
