7. Discuss the practical and theoretical differences between an interval training program used to improve the ATP-PC system and a program designed to improve the ATP production via glycolysis.
The ATP-phosphocreatine (PC) system is more suitable in conditions of high energy expenditure, whereas glycolysis is a step during cellular respiration.
What is cellular respiration?Cellular respiration is a chemical process by which aerobic cells generate energy in the form of ATP by using foods as a source of energy in presence of oxygen.
During cellular respiration, glycolysis (glycolytic pathway) is the first step for ATP production.
The ATP-PC system is anaerobic, works in hypoxia conditions (oxygen absence), and is faster to provide energy than cellular respiration.
However, the ATP-PC system is energetically less efficient than cellular respiration in terms of the number of ATP molecules produced per unit of glucose.

If a person inherits genes for a dark complexion and blue eyes from their parents, what aspect of inheritance does this refer to
The answer is Genotype.
What is Genotype?-
A phenotype is an individual's observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

The sum of the genetic traits in this population is called its V gene pooly. COMPLETE In guinea pigs, fur length is controlled by one gene. The Fallele generates long fur and the f allele generates short fur. Because only one F copy is needed to show the trait, if a guinea pig has the FF or Ff allele combination, they will have long fur. If they have the ff allele combination, they will have short fur. There is a total of 7 8 alleles in this population, There are 5 Falleles in the population. There are 3 ✓ falleles in the population. Look at the data for a guinea pig population to answer the following questions. COMPLETE Guinea pig 1: Long fur (FF) Guinea pig 2: Short fur (ff) If having long fur helps a guinea pig survive, what would you expect to see change in the population as it evolves? Guinea pig 3: Long fur (FF) DONE Cuinas nin 1. Innn fuar (Cf)
If having long fur helps a guinea pig survive, then it is expected to see the F allele is more common in the population as it evolves.
What is natural selection?Natural selection can be defined as the process of differential survival and reproduction of the fittest organisms.

D. A living organisms position in the flow of energy through an ecosystem.
Explanation:
Its like each step up in the food web/pyramid.
Trophic level is a living organism's position in the flow of energy through an ecosystem. The correct option is D.
A biological organism's place or function in the movement of energy through an ecosystem is referred to as its trophic level. It symbolises the ecological community's hierarchy of feeding.
A trophic level's inhabitants have comparable feeding habits and occupy a certain place in the food chain.
The first trophic level is occupied by the primary producers, including plants and algae, which use photosynthesis to transform sunlight into energy.
The second trophic level is occupied by herbivores that consume producers directly, followed by primary carnivores (predators that consume herbivores) on the third level, and so forth.
A complex network of energy flow and nutrient cycling occurs within an ecosystem at each trophic level as creatures consume and are consumed by one another.
Thus, the correct option is D.

Most water is reabsorbed from the filtrate by which region of the nephron?.
The main function of the nephron is to regulate water and other substances within the body where 67% of filtered water is reabsorbed in the proximal convoluted tubule by osmosis.
What is a nephron?It is a complex structure made up of elements such as the loop of Henle, the distal convoluted tubule, the proximal convoluted tubule, and the renal glomerulus.
Through the afferent arterioles, the blood plasma reaches Bowman's capsule, where the glomeruli are located, then the filtered fluid goes up to the proximal convoluted tube for another filtration to take place and part of the water is reabsorbed, the glucose, sodium and amino acids.
Therefore, we can conclude that water reabsorption along the nephron follows solute reabsorption and occurs in the proximal convoluted tubule by osmosis.

How do the kidneys compensate for acid-base imbalances?.
Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.
Acid-base ImbalanceWhen the amount of acid or base produced in the human body is greater than or less than the required amount of acid or base, and the rate of excretion by the kidneys is above or below normal, the body will experience an Acid-base imbalance situation.
To correct acid-base imbalance in the body the kidney will reabsorb HCO₃ form the urine and while secreting Hydrogen ions back to the urine.
Hence we can conclude that Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.
