How do dating methods help to support the theory of natural selection and biological evolution? How is it different than Darwin’s original ideas on speciation? Differentiate between absolute and relative dating techniques, giving one example of each. What is punctuated equilibrium?
Dating methods provide evidence of the age of fossils and the timing of key evolutionary events. Absolute dating techniques give a numerical age, while relative dating techniques provide a relative age. Punctuated equilibrium is a theory of evolution that suggests long periods of little change followed by rapid evolution.
Explanation:Dating methods help to support the theory of natural selection and biological evolution by providing evidence of the age of fossils and the timing of key evolutionary events. Absolute dating techniques, such as radiometric dating, provide an actual numerical age for fossils or rocks. For example, radiocarbon dating can be used to determine the age of organic materials up to about 50,000 years old. Relative dating techniques, such as stratigraphy, provide an understanding of the relative age of fossils or rocks. For example, the law of superposition states that in undisturbed rock layers, the oldest rocks are at the bottom and the youngest are at the top.
Darwin's original ideas on speciation did not involve dating methods, as these methods were not well-developed during his time. Instead, he focused on observational evidence from the natural world to propose his theory of evolution by natural selection.
Punctuated equilibrium is a theory in evolutionary biology that suggests that species may undergo long periods of little or no change, followed by relatively short periods of rapid evolution. This theory was proposed by Stephen Jay Gould and Niles Eldredge in 1972 as an alternative explanation to the gradualistic model of evolution proposed by Charles Darwin.

A cuticle occurs on the surface of organisms of many phyla and appears to be an advantageous feature. why have higher organisms not retained this structure?
While the cuticle has several advantages such as protection, they do not confer much advantage to larger eukaryotes. This is because of their limiting factor to growth (size). The cuticle would also restrict development of different skin structures such as fur. Additionally, while the cuticle provides leverage for muscular movements on arthropods, nematodes, and flatworms, it is not necessary for larger animals since the same function is rendered by the endoskeleton.

Scientists observed a rock stratum with fossils. If mollusks evolved before arthropods, where will their fossils be found?
Answer:
Fossils of mollusks would be found in lower strata than that of arthropods
Explanation:
Fossils are found in different layers of sedimentary rocks. The fossils of organisms that evolved earlier are found in the lower strata while those evolved later are preserved as fossils in the upper strata. If mollusks evolved before arthropods, fossils of arthropods would be present in upper layers while those of mollusks would be found in deeper layers.
If mollusks evolved before arthropods, their fossils would typically be found in older rock strata, deeper in the Earth's crust, relative to the rock strata containing arthropod fossils.
In the geological principle known as the Law of Superposition, it is generally accepted that in undisturbed rock layers, the older rocks are found at lower depths, and the younger rocks are found closer to the surface. This principle is fundamental to the study of stratigraphy and the dating of fossils within rock layers.
So, if scientists observe a rock stratum with fossils and they know that mollusks evolved before arthropods, they would expect to find mollusk fossils in rock layers that are deeper (older) than the rock layers containing arthropod fossils. This stratigraphic order aligns with the concept of relative dating in geology, where the sequence of fossil appearances in rock layers can provide insights into the order of evolutionary events.

Vestibular senses, kinesthetic sense, and skins senses all make up:
The correct answer is Vestibular senses, kinesthetic sense, and skins senses all make up: Somesthetic senses
Somesthetic senses are the sensation that is produced by the skin, joint, muscles, viscera and organs of balance. Merely looking at the word, the first part “soma” means body, esthetic, which is the second part, means feelings.
Further ExplanationWe have three somesthetic sense system, they are the skin senses, the kinesthetic sense, and the vestibular senses
The skin senses: It plays the role of receiving and transmitting information from the outside into the central nervous system. The sensory receptors collect information about pressure, temperature, including pain. Simply put, the skin senses is the sensory systems used for processing touch, cold, pressure and pain.
The kinesthetic senses: when your eyes are closed with your hand raised above your head, you surely know where hand is because there are receptors known as proprioceptors, which is responsible for telling you about joint movement or contracting. These special receptors are part of the body senses movement and tell you where your arms, hand, leg are located in relation to each other. This senses is known as kinesthetic senses. It is the senses of posture, muscle movement and strains on joint and muscle.
The vestibular sense simply refers to the sense of balance. This senses structure is present within the innermost chamber of the ear. Vestibular sense are structures in the air that tells you about the body position. Simply put, it refers to the senses of balance, acceleration and position in space.

Analyze and conclude 7. which, if any, of the blood samples tested cna the patient with type b+ blood receive? explain why. 8. explain how you were able to use your knowledge of how different types of blood react with anti-a, anti-b, and anti rh antibodies to determine the blood types of the four samples. 9. if a person has type a blood, he or she would have antibodies for what blood type? 10. why is type o negative blood known as the universal donor? why is o positive not a universal donor?
The blood types of the four samples were determined on the basis of the anti-factor present. The condition of each of the blood samples are given below:
If the blood sample reacts with anti-a, then the blood sample must not have an antigen A.If the blood sample reacts with anti-b, then the blood sample must not have an antigen B. If the blood sample reacts with anti-Rh, then the blood sample must not have antigen Rh.Based on this, it may be concluded the result as:
Blood reacts with anti-A possess Blood group B.
Blood reacts with anti-B possess Blood group A.
Blood reacts with anti-A and anti-B possess Blood group O.
What do you mean by Rh-antigen?Rh-antigen may be defined as the transmembrane proteins that are expressed at the surface of erythrocytes.
If a person has Blood type A, he or she does not have anti-A antigen and possesses anti-B antibodies. This is because the anti-A antigen is a foreign substance for their body. Due to the presence of the Rh factor, the O-negative blood type is known as the universal donor because it does not have positive Rh to stimulate any abnormal reaction in the body, while O-positive has the Rh factor which stimulates or triggers various abnormal reactions.Therefore, it is well described above.
