Which of the following statements about the acidic nature of gastric juice is true.
a. It partially digests food protein.
b. It converts the inactive digestive enzymes to their active form.
c. It halts the biological activity of proteins.
Answer: b. It converts the inactive digestive enzymes to their active form.
Explanation:
A. It partially digests food protein is true about the acidic nature of gastric juice.
Why is gastric juice acidic?The acidic nature of gastric juice plays a key role in breaking down food in the stomach, particularly protein. The main component of gastric juice is hydrochloric acid, which lowers the pH of the stomach to a highly acidic level, typically between 1.5 and 3.5.
This low pH helps to denature proteins, which makes them easier to break down by digestive enzymes like pepsin. Pepsin is an enzyme that breaks down proteins into smaller polypeptides, and its activity is greatest in an acidic environment.

the mass of dna per nucleus in a certain fungus ranges from 4 to 10 picograms. nuclei with 5 picograms of dna are most likely derived from cells in which of the following parts of the cell cycle?
The nuclei with 5 picograms of DNA are most likely extracted from cells in the c) G1 phase of the cell cycle.
The G1 phase is the first phase of the cell cycle, during which the cell grows and performs all the metabolic functions necessary for cell division. This phase is also known as the gap phase because it is the period of time between the end of cell division and the beginning of DNA replication.
The G1 phase typically lasts for about 10-12 hours in most cells. During this phase, the cell grows in size and synthesizes all the proteins and other molecules needed for DNA replication.
The cell also replicates its organelles, so that each daughter cell will have a complete set. Finally, the cell checks its DNA to make sure it is intact and ready for replication. If the DNA is damaged, the cell may enter a special checkpoint where it can repair the damage or, if the damage is too severe, the cell may undergo apoptosis (programmed cell death).
Hence the correct option is c).

Photosynthesis is an example of a chemical reaction because: c.) endergonic; light energy is used to build chemical bonds.
What is endergonic reaction?An endergonic reaction requires free energy to proceed and example of an endergonic reaction is photosynthesis. Photosynthetic organisms perform the reaction using solar photons to drive the reduction of carbon dioxide to glucose and oxidation of water to oxygen.
Photosynthesis starts with molecules of water and carbon dioxide. When light is added, then molecules break apart to rearrange into new molecules of glucose and oxygen.
Photosynthesis is an endergonic reaction because plants cannot start the photosynthesis until they absorb light energy. Chlorophyll absorbs the light energy, which is used for the photosynthesis reaction to occur.

How much more atp is generated from glucose 6-phosphate, compared to glucose, when it is metabolized by the glycolytic pathway?.
2 ATPs are generated from glucose 6-phosphate during the glycolytic pathway.
The glycolysis pathway, which is a series of enzyme-mediated steps, is used to metabolize G6-P in the cytoplasm of the cell. The first step of glycolysis is the isomerization of glucose-6-phosphate (G6P) into fructose-6-phosphate, which creates triose-phosphate and two pyruvate molecules as well as a small amount of ATP (net gain of 2 ATP molecules). The majority of ATP is then produced by the aerobic oxidation of pyruvate in differentiated cells. Although glucose is frequently regarded as the primary energy source for cells, it is actually primarily a major supply of carbon skeletons for cell growth and survival. Indeed, under some circumstances, particularly during prolonged fasting or during cell proliferation, glucose oxidation to CO₂ to provide energy should be avoided to allow the delivery of essential functions.

Dna replication relies on the blank______ of dna strands according to the blank______ rule.
DNA replication relies on the ___complementarity___ of DNA strands according to the ___AT/GC___ rule.
Define DNA replication.DNA replication is the process by which genomic DNA is copied into cells. Before a cell can divide, it must first copy (or replicate) its entire genome so that each resulting daughter cell has its own complete genome. This is a semi-conservative process, meaning that each new copy of DNA contains one parent strand and one new strand of the original DNA. Replication is an essential process because each time a cell divides, the two new daughter cells must contain the same genetic information or DNA as the parent cell. It is found in the nucleus of eukaryotic cells and the nucleoid region of prokaryotic cells. DNA replication occurs in the S phase of the cell cycle before cell division
The principle of complementarity governs both transcription and DNA replication due to the fact that when two DNA or RNA sequences are arranged antiparallel to each other, the nucleotide bases at each position in the sequences are complementary or mirror images.

What is the advantage of the branching design of the bronchioles on our lungs into 700 million alveoli?
Your lungs' principal airways (bronchi) split into bronchioles, which are progressively smaller passageways that join to tiny air sacs (alveoli).
The lungs have a high surface area to volume ratio due to the many and tiny size of the alveoli. This removes the constraints often imposed by the concomitant increase in size and weight of the gas exchange system, allowing animals to grow to considerably bigger sizes.
What about lungs?Respiration, a process of gas exchange, is the major purpose of the lungs (or breathing).Carbon dioxide, a waste product of metabolism, leaves the blood during breathing while oxygen from the incoming air enters. Reduced lung function refers to the lungs' diminished capacity to exchange gasses. When you breathe in and out, you may have lung pain on one or both sides of your chest. Technically, because the lungs have so few pain receptors, the discomfort isn't emanating from inside them. Instead, the lining of the lungs, which does include pain receptors, might be the source of the discomfort.Networks of intricate tubes that make up our two lungs are hung on each side of the heart in the chest cavity by a support system formed of elastic fibers. The nose serves as an air filter by capturing dust particles on its hairs as it draws air in through the mouth and other openings.

Dicu how croing-over lead to greater variability of phenotype. Give an example to help explain your anwer
In Crossing-over, a part of the chromosome will be exchanged with another part in phenotype.
Crossover provides for the exchange of DNA sequences between homologous chromosomes during meiosis. This process forms a new arrangement of the genetic information stored on the maternal and paternal chromosomes. New combinations of genes residing on the same chromosome increase the genetic diversity of offspring, making them different from their parents.
For example, one chromosome contains two mutated genes of hers that affect a particular trait in an organism. Without crossbreeding, both mutated genes are passed on to offspring. However, the process of crossover can segregate genes between two homologous chromosomes. Since only one of the homologous chromosomes is inherited from one parent, the odds of inheriting both mutated genes are reduced and the offspring will have only one mutated gene of hers.
