Answer:

Given the sequence of bases of the RNA GGAUUC, the possible mutations would be:

a. Substitution: GGAUUC → GGAAUC

b. Insertion: GGAUUC → GGACCUUC

c. Deletion: GGAUUC → GG_UC

Explanation:

The fragment observed is recognized as RNA, due to the presence of uracil (U). The mutations observed in this fragment are derived from a mutated DNA molecule, which was transcribed into mRNA

Substitution is a molecular mutation that occurs when one nitrogenous base is changed to another in the DNA sequence. GGAUUC → GGAAUC Mutated DNA: CCTTAG
Insertion occurs when entire bases or segments are added to the original genetic material, resulting in a longer molecule. GGAUUC → GGACCUUC Mutated DNA: CCTGGAAG
Deletion is a type of mutation where genetic material is lost, which can be nitrogenous bases or segments of the molecule. GGAUUC → GG_UC Mutated DNA: CC_AG

Each of these mutations can have an effect on protein synthesis, affecting the structure or function of the final protein.

What affect does binding a gas to a hemoglobin have on homeostasis

frutty [35]

Explanation:

Haemoglobin acts as a protein buffer.

Haemoglobin- oxygen binding in the blood is part of acid-base homeostasis. The cells within the brain or CNS ensure that more oxygen is taken into the lungs at a faster rate while carbon dioxide is removed; this aids in gaseous exchange and maintaining the pH of the blood- oxygen concentrations are kept high within the blood stream as blood circulates through the body.

Blood pH levels are typically within 7.35 --7.45. it is regulated by coordinated activity controlled by the brain, and carried out by the kidneys and lungs; along with red blood cells. When the body needs more oxygen, CO2 (as waste from cellular respiration), in the blood is converted to biarbonate increasing acidity; at the same time, H released in the reaction, and buffered by haemoglobin.

-The haemoglobin undergoes reduction by oxygen, and the pH level is maintained.

Further Explanation:

A typical oxygen disassociation curve shows haemoglobin’s percentage saturation at different oxygen concentrations (partial pressures). This shows the equilibrium between oxyhaemoglobin (haemoglobin in its oxygen bound state and haemoglobin (free of oxygen molecules). The saturation generally increases with increased partial pressures of oxygen.

Haemoglobin is an oxygen binding protein comprising four iron-based peptide subunits: two α subunits and two β subunits. Each molecule of haemoglobin has the ability to bind up to four oxygen molecules at a time; this occurs via cooperative binding- meaning that with increased haemoglobin- oxygen binding at the protein haemoglobin’s subunits,(where oxygen is a ligand) there is an increase in its affinity for oxygen.

This is because there is a conformational change in the hemoglobin molecule due to the altered orientation of the protein’s secondary structures, making it easier for a second molecule of oxygen to successively followed by more O2-Haem binding until the molecule is saturated- at this point the curve plateaus- it reached its carrying limit.

Hormones bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis. It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions.

Name the three fossil fuels and tell how Americans use them and the impact they have on our country?

stich3 [128]

The United States gets 81% of its total energy from oil, coal, and natural gas, all of which are fossil fuels. We depend on those fuels to heat our homes, run our vehicles, power industry and manufacturing, and provide us with electricity. Eventually, the degree to which we depend on fossil fuels will have to decline as the planet’s known supplies diminish, the difficulty and cost of tapping remaining reserves increase, and the effect of their continued use on our planet grows more critical. But shifting to new energy sources will take time. In the meantime, how do we use fossil fuels in the most efficient and environmentally responsible way possible?
