Answer:
The correct answer is A and D
Explanation:
According to Russell's conception that lies in natural proton gradients. He states that Four billion years ago, alkaline fluids bubbled to produce mildly acidic oceans (As CO2 levels were about a thousand times higher, and it reacts with H2O to form carbonic acid, rendering the oceans mildly acidic). Acidity is just a measure of proton concentration, higher in the oceans than in vent fluids. This difference has given rise to a natural proton gradient across the vent membranes that had the same polarity (outside positive) which is similar to the electrochemical potential as modern cells have. This might be the reason that last universal common ancestors of all the three domains have evolved proton pumps.
Greater light intensity would mean a faster rate of photosynthesis in plants. photosynthesis takes in carbon dioxide and water to produce glucose and oxygen. therefore, a greater light intensity would mean faster oxygen production
Answer:
Malignant melanoma cells would have active telomerases that constantly replenish and lengthen telomeres.
Explanation:
Telomerase can be described as enzymes which add the repetitive sequences called telomeres at the end of a chromosome. Telomeres can be described as repetitive sequences at the end of the chromosome which are involved in protecting the chromosome from any damage.
In a normal skin cell, the telomeres will shorten with time. But in a malignant skin cell, the telomerase will add the repetitive sequence again and again. The telomers will not be able to shorten.
When evacuating victims and personnel currently facing danger to their lives, an establishment should have a safe evacuation routes. The evacuation route should be placed in the Exclusion Zone which means that it is a large site with obstructions and not safe until the safety area is reached. Another would be developing the Contamination Reduction Zone which is designed for individuals that are facing chemical dangers. Decontamination while inside the building is inadvised but would be applied in the arrival to the said zone. An access to potential routes should be available. Obstructions like locks, blocked doors are inadvisable. Routes should be free from items that are not needed within the area. Also, multiple routes that are separated from each other is recommended for evacuating numerous amount of people at the same time or when fire blocks one, there would be another choice available.
Plasma proteins account at least 8% of the plasma, they contribute to osmotic pressure and maintain water balance in blood and tissues, other functions includes transport and enzymatic activities. Plasma proteins include albumin, fibrinogen and globulin (alpha, beta and gamma). Globulin proteins may be used to fight infections such that gamma globulin antibodies are released by the plasma during immune response.
