Not really a question but just a reminder that YOU ARE WORTH IT!!! Dont let anyone tell you otherwise. You are beautiful and smart and brave. No matter if your apart of the LGBTQ community or if you wear a hijab. Dont hurt yourself just so you can look better. Even though I have no Idea what yall look like you are hotter than the sun. In the words of Melanie Martinez, Your body is imperfectly perfect. Always stand up for your beliefs and never ever stop. YOU ARE WORTH IT What percentage would my grade be if I got a 50% on a project that is worth 20% of my grade and my grade is 87%/B+.How much would my grade go down?PLEASE HELP ME Which best compares kinetic energy and temperaturo?A.

The options have an estimated fair value of $6 each. To provide additional incentive for managerial achievement, the options are not exercisable unless divisional revenue increases by 6% in four years. Blue initially estimates that it is not probable the goal will be achieved, but in 2022, after three years, Blue estimates that it is probable that divisional revenue will increase by 6% by the end of 2023.

(NEED HELP ASAP) BRAINLIEST NO FAKE ANSWERS1.A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans. After doing DNA analysis, they determine that the organisms share the following percentages of DNA:Organism A and humans share 85% of their DNA.Organism B and humans share 80% of their DNA.Organism C and humans share 90% of their DNA.Based on this information, which order should they go on the cladogram (from least related to most related)?(1 point)A, B, C, humansC, B, A, humansC, A, B, humansB, A, C, humans2.A cladogram shows the evolutionary relationship between humans, chimpanzees, and gorillas. The cladogram currently shows humans and chimpanzees with a more recent common ancestor compared to gorillas. Which piece of evidence, if true, would most likely weaken this hypothesis?(1 point)Fossils of humans appear in deeper sedimentary rock layers compared to fossils of chimpanzees.Amino acid analysis of the cytochrome c protein shows significant differences in the sequence of amino acids between humans and gorillas.DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorillas DNA sequence.The cells of the eye in embryos of gorillas and humans follow a similar pattern of development while chimpanzee embryos are different.3.The forelimbs of bats and humans have a very similar bone structure even though they appear very different on the outside. These structures are known as __________ because they result from species evolving __________.Which of the following answer choices correctly completes the above statement?(1 point)homologies; similar adaptations in similar environmentsanalogies; from the same common ancestoranalogies; similar adaptations in similar environmentshomologies; from the same common ancestor4.All vertebrate embryos have a tail and gill slits at some point during embryonic development. What does this suggest about vertebrates?(1 point)The embryos of these species require these structures to survive.These species evolved in similar environments.These species have the exact same DNA sequence.These species share a common ancestor.5.Fossil A is found closer to the surface compared to Fossil B. Which of the following conclusions can be made based on this statement?(1 point)Fossil A is from an older species than Fossil B.The species of Fossil A existed at the same time as the species of Fossil B.The species of Fossil A evolved from the species of Fossil B.Fossil B is most likely older than Fossil A.6.Vertebrate embryos all follow a very similar developmental process. Which statement could explain this similarity?(1 point)All vertebrates require the same nutrients during embryological development.All vertebrates develop a backbone that protects the spinal cord.All vertebrates inherit the same sequence of DNA from their parents.All vertebrates live in similar environments which require the same adaptations.7.Some mutations, or changes in the sequence of DNA, do not have any effect on the characteristics of the organism. Why is this?(1 point)The immune system repairs the mutated sequence during development.The protein built from this mutated sequence is deactivated by the cell.The mutated sequence still codes for the same amino acid.The cell recognizes mutations and ignores them when expressing the gene.8.What is typically studied when analyzing not-yet-born (or unhatched) animals?(1 point)embryological developmentevolutionary theorycausal recordsDNA sequencing9.What can scientists analyze to get a better understanding of how plants and animals evolved from a common ancestor?(1 point)petrified bones and imprints of plantsDNA moleculesvertebrate embryoslife cycles and behaviors10.How can embryos help scientists understand evolution?(1 point)Embryos contain the code for all life on Earth.Embryos go through various stages that suggest the animals evolutionary process.Embryos provide evidence for which life forms existed at the same time.Embryos are frequently fossilized and illustrate change over time.11.Astronomers have made great strides in sending probes out to other planets and moons in our solar system. If they were to find a living creature some place other than Earth, how could DNA analysis help them better understand the organism? Explain in 12 sentences.(2 points)12.In 1973, biologist Theodosius Dobzhansky wrote an essay titled Nothing in Biology Makes Sense Except in the Light of Evolution. Why is evolution so important for understanding biology? Explain your answer in 12 sentences.(2 points)13.You are a scientist tasked with writing a journal article on the evolution of alligators. In 35 sentences, describe the different forms of evidence you might use to analyze the evolution of alligators.(4 points) Can someone plzzzz helpppp meeeee!!! a 420$ dressed is 20% off, how much is the sales price?

It is a dream of a land where men of all races, of all nationalities and of all creeds can live together as brothers. The substance of the dream is expressed in these sublime words, words lifted to cosmic proportions: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty, and pursuit of happiness."The sentence that includes the phrase that all men are created equal is an example ofa reason.a claim.evidence.rhetoric.Please help!
