Explanation:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
The preserved remnants or traces of extinct animals, plants, and other organisms are known as fossils. Because they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.
What is evolution?According to the idea of evolution, modern life forms have evolved from more ancient ones.
The original theory suggested that this occurred slowly and gradually, but fossil evidence suggests that the process occasionally went wrong and engaged in some very bizarre experiments.
Therefore, they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.

1. Will loves to go fishing in the coastal estuary. He brings home his catch every weekend and bakes the fish for dinner. The next time he goes to his favorite fishing area, a sign is in place, warning residents of high heavy metals in the water. Which statement best explains the impact of eating fish from the estuary?
Heavy metals can biomagnify in large fish, making human consumers ill.
Heavy metals are water soluble; humans can eat them in small amounts.
Large fish will die from the heavy metals, but small fish can be consumed.
Will should avoid small fish but can collect large fish with less heavy metals.

In an experiment that compares a combination mental-physical practice condition to an all-mental practice condition, an all-physical practice condition, and a no practice condition, the typical results show that participants in the combination mental-physical practice condition would learn the skill
a. as well as or better than those in the all-physical practice condition.
b. about as well as those in the all-mental practice condition.
c. about as well as those in the no practice condition.
d. The results would depend on the combination of the amount of mental and physical practice.
The combination mental-physical practice condition is effective to learn the skill as well as or better than those in the all-physical practice condition. Mental-physical practice enhances both cognitive and physical skills.
Mental practice, also known as mental/skill rehearsal, refers to the cognitive (i.e., thinking) rehearsal of a given skill prior to its execution.
It has been shown that mental practice can be effective for enhancing the performance of both cognitive and physical skills.
The mental-physical practice has been shown to be helpful to enhance self-motivation, confidence, and reduce feelings of anxiety.
Mental practices always must be employed to supplement physical practices instead of replacing such physical exercises.

Along one side of a DNA molecule, the nucleotides are connected to each other by ________ bounds between _______
Answer:
Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide.
Explanation:
Along one side of a DNA molecule, the nucleotides are connected to each other by covalent bonds between the phosphate group pf one nucleotide and the third carbon atom of the pentose sugar (deoxyribose sugar) in the next nucleotide.
How nucleotides are arranged in DNA?Two nucleotides are attached via a phosphodiester bond to form dinucleotide. Another nucleotides are added in same manner to form polynucleotide chain.
In this polynucleotide chain, the nucleotides are connected to each other by covalent bonds between phosphate group of one nucleotide and third carbon atom of deoxyribose sugar and forms a phosphate backbone of DNA.

the spinal cord achieves the function of locomotion through __________.
Answer:
groups of neurons called central pattern generators
The spinal cord achieves the function of locomotion through groups of neurons called central pattern generators, hence option A is correct.
What are the groups of neurons in the spinal cord?Even when cut off from the brain and sensory inputs, "central pattern generators" (CPGs) nerve networks in the spinal cord can generate rhythmic motions like swimming, walking, and hopping.
In the absence of sensory or descending inputs that contain precise timing information, central pattern generators are neural networks that, when triggered, may create rhythmic motor patterns like as walking, breathing, flying, and swimming.
The spinal cord facilitates the movement of bodily components, accidents frequently result in people being unable to utilize certain body parts like the legs.
Therefore, the spinal cord achieves the function of locomotion through groups of neurons called central pattern generators, hence option A is correct.
