A tundra biologist would make sure that the area of tundra they are working on stays healthy by checking plant and animal life for signs of harm or pollution. Wake up, get ready, drive to work location, observe wildlife, collect samples, answer questions for public, write papers on how to reduce pollution or harm to tundra animals and why the animals have their uses. Its important because it improves our environment for future generations. Hope this helps :D
Modifications of genes in sex cells
Answer: C). Oxygen binding
Explanation: Hemoglobin is a protein present in the red blood cells that transports oxygen to the body cells and tissues. Hemoglobin has four subunits with four binding sites: one binding site on each protein subunit. Hemoglobin exists in two states: the tensed (T) state and the relaxed (R) state. The T state has low affinity for oxygen while the R state has high affinity for oxygen. The binding of oxygen to the T state triggers a conformational change in the protein and its transition to R state. The binding of oxygen to one binding site on hemoglobin increases the binding of oxygen to the remaining subunits, this phenomenon is known as cooperativity.
Answer:c
Explanation:
Thymine is found in dna only and its replaced with uracil in RNA
