Answer:
In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
The story of the evolution of early birds winds through the chapter as an example of the dynamic nature of science. Why is it likely the dinosaur-bird evolutionary tree will be modified again?
Choose one:
A. The fossil record is incomplete, so the relationship between birds and dinosaurs will never be resolved, leaving the evolutionary tree to always be questioned.
B. The process of science is one of continual discovery, and new information is likely to be discovered that could change our current understanding.
C. Because dinosaurs are extinct, the dinosaur-bird evolutionary tree can never be resolved.
D. Because of the rapid advancements in technology, DNA analyses will ultimately prove that birds did not descend from dinosaurs.
Answer: B the process of science is one….
Explanation:
The process of science is one of continual discovery, and new information is likely to be discovered that could change our current understanding. Option B is correct.
The process of scientific inquiry is characterized by its dynamic and evolving nature. This applies to fields such as paleontology and evolutionary biology, including the study of the evolution of early birds and their relationship to dinosaurs.
The fossil record is incomplete, and while it provides valuable insights into the history of life on Earth, it does not capture every species that ever existed. As new fossils are discovered and technologies improve, our understanding of the relationships between different species, including the evolution of early birds from dinosaurs, can change.
Advancements in technology have allowed scientists to gather more detailed information from fossils, perform more precise analyses, and even extract DNA from ancient remains. These technological innovations can lead to new discoveries and a better understanding of the evolutionary relationships among different organisms.
Additionally, the scientific community encourages skepticism and critical evaluation of existing theories. New evidence, whether from fossils, genetic studies, or other sources, can prompt researchers to reevaluate and modify their understanding of the dinosaur-bird evolutionary tree.
In conclusion, the dynamic nature of science, the ongoing discovery of new evidence, and the advancement of technology all contribute to the likelihood that the dinosaur-bird evolutionary tree will continue to be refined and modified as our understanding of the past evolves. This is a fundamental characteristic of the scientific process, which seeks to refine and improve our knowledge over time.

What is the route of blood flow in a closed system?.
Answer:
In a closed circulatory system, blood is contained inside blood vessels and circulates unidirectionally from the heart around the systemic circulatory route, then returns to the heart again, as illustrated in Figure 21.2a.
Explanation:
Which of the following directly causes deforestation?
A. Wind
B. Biomass
C. Nuclear fission
D. solar
Answer:
The answer is C. Wind levels usually remain static in a specific location, so any existing life is not affected much. Biomass contributes to growth as it enriches the soil. Solar (assuming it's referring to the widespread increase in the use of solar energy) could actually be indirectly beneficial to forests. Nuclear fission, however, can cause harm to plants. Some known effects on plant life include stunted growth, reduced germination, and genetic mutations in addition to the direct burning that could be inflicted on plants in some cases.

what's kreb cycle? explain in brief
Answer:
Kreb cycle is the sequence of reactions by which most living cells generate energy during the process of aerobic respiration. It takes place in the mitochondria, using up oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.
Explanation:
Definition:
A cycle of reactions catalyzed by enzymes in which the pyruvate derived from nutrients and converted to Acetyl Coenzyme A is completely oxidized and broken down into carbon dioxide and water to produce high-energy phosphate compounds, which are the source of cellular energy.
In eukaryotes, the Krebs cycle reactions take place in the mitochondrial matrix, a dense solution that surrounds the mitochondria crests: in addition to water, the matrix contains all the enzymes necessary for the biochemical reactions of the cycle, coenzymes, and phosphates.
Equation:
The overall reaction for the citric acid cycle is as follows: acetyl-CoA + 3 NAD+ + FAD + GDP + P + 2H2O = CoA-SH + 3NADH + FADH2 + 3H+ + GTP + 2CO2.
