Answer:
See the answer below
Explanation:
Watson and Crick modeled the structure of the DNA as being made up of 2 strands with each strand composed of a long chain of nucleotide bases. The DNA. The 2 strands are said to be associated by a hydrogen bond and are twisted around each other in a ladder-like manner to form a helix structure.
Specifically on the bases, Watson and Crick modeled that the nucleotide bases component of one strand of a double helix DNA are complementary to the nucleotide bases of the other strand according to the base-pairing rule.
The base-pairing rule states that adenine always pairs with thymine while guanine always pairs with cytosine. This thus means that with the nucleotide sequence of one strand known, the sequence of the other strand of a double helix DNA can be determined.
b. phagotrophs
c. osmotrophs
d. saprozoic feeders
Answer:
The correct answer will be option-B.
Explanation:
Protist is the group of the organism which is eukaryotes but nither considered true animals, fungi and plants.
Their mode of nutrition is either osmotrophic or phagotrophic. The phagotrophic feeds on the macroparticles like organic particles by surrounding the particle and swallowing it through phagocytosis. The ingested particle gets digested inside the body pf the organism. The phagotrophic organisms are like amoeba and dinoflagellates.
Thus, Option-B is the correct answer.
B.There is an increase in the amount of oxygen being delivered to the muscle cells during the process of aerobic respiration.
C.There is an increase in the amount of glucose being produced in the muscle cells during the process of aerobic respiration.
D.There is an increase in the amount of lactic acid being produced in the muscle cells during the process of anaerobic respiration.
The reason the basketballplayer experiences this muscle soreness after a workout is there is an increase in the amount of lacticacid being produced in the muscle cells during the process of anaerobicrespiration. The correct option is D.
Muscle fatigue is characterized by a reduction in maximal force or energyproduction as a result of contractile activity.
It can start at various points along the motorpathway and therefore is typically classified into central and peripheral components.
Muscle fatigue is a sideeffect that makes it difficult to move normally. Some people feel a stingingsensation in their muscles.
They may also be tired all the time and lack the energy to perform daily tasks. Muscle fatigue is frequently caused by exercise.
The most crucial etiology of skeletalmuscle fatigue has been identified as intracellular acidosis caused primarily by lactic acid accumulation.
Thus, the correct option is D.

Answer:D
Explanation:.........
B. Algae is a meaningful term for taxonomists.
C. Algae represent a group of closely related organisms that share a common ancestor.
D. Algae is a general term for several aquatic organisms that are photosynthetic.
D. or B.because algae is cabable of producing oxygen through photosynthesis
Pepsin is found in the stomach. Salivary amylase is found in the mouth. Arginase is also found in the liver. The pH of the pepsin in the stomach is acidic. The pH of the pepsin in the stomach is acidic (around 2), the mouth pH is nearly neutral, and the liver pH is basic.
Different organs of the body function well at different pH levels because enzymes exhibit their best activity in a specific pH range The enzyme that acts in the stomach can't act in the mouth due to a change in pH. The mouth has a nearly neutral pH, ranging from 6.5 to 7, and in this place, the salivary amylase works best and carries out the initial digestion of the carbohydrates. Pepsin works in stomach having a pH nearly 2.
Hence, the pepsin enzyme in the stomach works best at an acidic pH of about 2. The amylase works best at neutral pH. The liver enzyme arginase works best at a basic pH.

Answer:
the answer is B ( the stomach is more acidic thank the mouth, which is more acidic than the liver
Explanation:
Answer:
would increase, population, and chances of getting more food for survival.
Explanation:
By the increase in secondary consumers, that would give more food and energy and the ease of finding food for the tertiary consumers, which will give more energy for activities and therefore sexual activity can no longer be lacking the energy barrier, and due to that the population of tertiary consumers increases, eventually leading to the same effect and increase in Quaternary consumers.
