seconds to almost 4 seconds?
Answer:
I am not 100% sure but my best guess would be the object is moving backwards/falling.
Explanation:
The graph shows the position of the object going from almost 9.0 to below zero. There are many situations that could fit this. Such as, something going above and below sea level. OR something moving in front and behind a certain point. My best guess would be moving backward towards an object OR falling from a certain point.

Cell is regarded as the basic and fundamental unit of life according to the cell theory. Every living organism must possess a cell, which contains organelles responsible for performing specific tasks. Cells of plants and animals are different in some ways and similar in other ways. Some of the true facts about plant and animal cells in accordance to this question are:Plant cells have chloroplasts while animal cells do not. This is why plant cells can synthesize their own food via photosynthesis. Plant cells have one large vacuole located at the centre of the cell while animal cells have several smaller vacuoles scattered throughout the cell.Plant cells have cell walls while animal cells do not. The cell wall of plants is made up of cellulose and gives the cell shape and strength.

How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution. bones (homologous structures) are used for similar uses if the organisms are more closely related bones (homologous structures) are used for similar uses if the organisms are more closely related sections of DNA are more similar in organism more closely related. sections of DNA are more similar in organism more closely related. organisms that are more closely related are found with similar embryonic structures. organisms that are more closely related are found with similar embryonic structures. fossils in various layers are more closely related if they are in the same layer
Answer:
Sections of DNA are more similar in organism more closely related
Cytochrome c is used to provide evidence for evolution because most animals have this protein and is has undergone very little changes in these organisms such that more closely related species have the most similarity in amino acid sequence of cytochrome c
Explanation:
Cytochrome c is a protein found in mitochondria and is an important enzyme in cellular respiration. Cytochrome c is a highly conserved (have undergone very little changes) protein that in found in many different species of organismsmsuch as plants, animals, and many unicellular organisms. Cytochrome c is made up of about 104 amino acids linked together by peptide bonds. Being a small-sized molecule (molecular weight about 12,000 daltons) also makes it easier for evolutionary studies to be conducted on it.
Organisms that are most closely related have the most similarity in the amino acid sequence of the cytochrome c molecule. The amino acid sequences in cytochrome c molecule present in organisms is as a result of the information in their DNA.Thus, sections of DNA are more similar in more closely related organisms.

liquid outer core, it is still solld because -
Answer: The inner core is solid because it is made of very dense, or heavy, materials - like iron and nickel. Even though it is very hot, these materials don't "melt" very easily, so they stay solid. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher.

Which of the following is not an example of coevolution? A. Prey evolve faster running to escape, and predators evolve to smarter at catching prey. B. Predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth. C. Plants evolve chemical defenses and herbivores evolve ways to neutralize the chemicals. D. Insects evolve green wings to blend into the environment, and predators evolve better eyesight to find the prey. Explain why.
The statement 'predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth' is NOT an example of coevolution.
Coevolution is an evolutionary process where two or more species evolve in a parallel manner.Coevolution is caused by an evolutionary race between species.In general, coevolution is caused by selective pressures between one taxonomic group on another.In conclusion, the statement 'predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth' is NOT an example of coevolution.

Which statement correctly describes a difference between asexual and sexual reproduction?
Answer:
B) Asexual reproduction involves one parent, and sexual reproduction involves two parents.
Explanation:
In asexual reproduction, offspring formed from only one parent whereas, in sexual reproduction, offspring produces from two parents. The offspring is identical to the parent in asexual reproduction while on the other hand, offspring is different from their parents. Sexual reproduction increases the chances of survival of the species due to genetic diversity whereas asexual reproduction has limited chances of survival due to lack of genetic diversity.
Asexual reproduction involves the production of offspring without the involvement of gametes, resulting in genetically identical offspring. On the other hand, sexual reproduction involves the fusion of gametes from two parents, resulting in offspring with genetic variation.
Asexual reproduction and sexual reproduction are two different methods of producing offspring in living organisms. Here are the differences between them:
1. Asexual reproduction:
Asexual reproduction involves the production of offspring from a single parent without the involvement of gametes (sex cells). This means that the offspring are genetically identical or clones of the parent.
Examples of asexual reproduction include binary fission in bacteria, budding in yeast, and regeneration in starfish. In binary fission, a single-celled organism divides into two identical cells. In budding, a small bud grows on the parent organism and eventually detaches to become a new individual. In regeneration, an organism can regrow a lost body part and develop into a complete organism.
2. Sexual reproduction:
Sexual reproduction involves the fusion of gametes from two parents to produce offspring. Gametes are specialized sex cells, such as sperm and eggs, which contain half of the genetic material of the parent.
In sexual reproduction, the offspring inherit genetic information from both parents, leading to genetic variation. This genetic diversity is important for the survival and adaptation of species over time.
Examples of sexual reproduction include humans, animals, and many plants. In humans, sperm from the male parent fertilizes an egg from the female parent, resulting in the formation of a zygote. The zygote then undergoes development to form a new individual with a unique combination of genetic traits.
