Hello, when Shelly's blood pressure rose her physical responses to missing the bus were --stress reactions.
Please click the thanks button and brainiest to help me stay on here thanks.
<span>If
a geological barrier (like a continent splitting apart) separates a
population of primates, then each population will evolve separately to
fit the different conditions of their environments.
As a hypothetical example, if one part of Pangea went north, the
primates on that part would adapt to cold temperatures. If the other
part went toward the equator, those primates would adapt to heat and
direct sunlight. Eventually they would evolve into different species
over many generations.</span>
Answer: B) energy released from exergonic reactions.
Explanation:
Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).
Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.
The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.
In mid-ocean ridge areas, ocean water is cycled through the crust because of the high heat flow in the area. Water in the rock is heated over the magmas, rising up and drawing in cold water from the sides. This process is occurring all over the world, and is the primary means for maintaining ocean salinity in a relatively constant range over the long term, as elements in the sea water when it is heated react with the rocks. There is so much water flow, cumulatively over the entire world, that this process basically buffers ocean chemistry.
Obviously large increases or decreases in salinity can and do occur in isolated basins that do not have free exchange with the open oceans.
Answer: for me the best option is D.
Explanation: lets explain this.
Cellular respiration begins with a process that divides the glucose within the cells making it readily available as a source of energy. This process can occur without oxygen (anaerobic respiration) or in the presence of oxygen (aerobic respiration). Anaerobic respiration generates more excess waste (lactate) than aerobic . Besides, high levels of lactate build within the muscle cells. Excess lactate slows the cellular respiratory process and is experienced as a burning sensation in the muscles if exercise continues.
