The correct answer among the choices presented above is option D. The uterus is a pear-shaped muscular organ that houses the developing fetus. It is the organ located in the lower body of a female mammal. It is a major reproductive organ of most mammals.
Answer: Option 'd' is correct.
Explanation:
Since we have given that
Number of fish caught = 100
Number of tagged fish in catch = 24
So, total number of the fish in the pond is given by
Number of fish caught + Number of tagged fish in catch
=100 +24
= 124
So, the best estimate to find the number of fish in the pond is 124.
Hence, Option 'd' is correct.

Answer:
(D) acetyl CoA, NADH, H+, and CO2.
Explanation:
The given explanation is about oxidative decarboxylation of pyruvate into acetyl CoA and carbon dioxide. The reactions are catalyzed by enzyme complex pyruvate dehydrogenase. During the reaction, pyruvate loses one of its carbon atoms in the form of CO2 and the rest of two carbons form the acetate which in turn combines with CoA to form the acetyl CoA.
Since it is an oxidative decarboxylation, the released electrons are accepted by NAD+ which in turn is converted into NADH + H+.
Overall, there is the formation of one molecule of acetyl-CoA, CO2 and NADH + H+ each from one molecule of pyruvate.
Answer:
Natural science is a branch of science concerned with the description, prediction, and understanding of natural phenomena, based on empirical evidence from observation and experimentation. Mechanisms such as peer review and repeatability of findings are used to try to ensure the validity of scientific advances.
Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, Earth science, and astronomy. These branches of natural science may be further divided into more specialized branches (also known as fields). As empirical sciences, natural sciences use tools from the formal sciences, such as mathematics and logic, converting information about nature into measurements which can be explained as clear statements of the "laws of nature".[1]
Modern natural science succeeded more classical approaches to natural philosophy, usually traced to Taoists traditions in Asia and in the Occident to ancient Greece. Galileo, Descartes, Bacon, and Newton debated the benefits of using approaches which were more mathematical and more experimental in a methodical way. Still, philosophical perspectives, conjectures, and presuppositions, often overlooked, remain necessary in natural science.[2] Systematic data collection, including discovery science, succeeded natural history, which emerged in the 16th century by describing and classifying plants, animals, minerals, and so on.[3] Today, "natural history" suggests observational descriptions aimed at popular audiences.[4]
