PLEASE HELP!! WILL MARK BRAINLIEST AND THANK YOU!!! IM DESPERATE!!Find the area. ______m The 8 kg block is then released and accelerates to the right, toward the 2 kg block. The surface is rough and the coefficient of friction between each block and the surface is 0.4 . The two blocks collide, stick together, and move to the right. Remember that the spring is not attached to the 8 kg block. Find the speed of the 8 kg block just before it collides with the 2 kg block. Answer in units of m/s. Find the ratio of the surface area to volume of the rectangular prism brlow Which of the following best describes why invertebrates isn't considered a scientifically valid word when classifying animals? A. The term invertebrates describes all animals, so is not helpful in classifying organisms within the animal kingdom. B. The term invertebrates is unhelpful because all animals possess some sort of backbone or notochord. C. The term invertebrates classifies animals haphazardly based on a missing characteristic rather than a common one. D. The term invertebrates is too vague, since all animals evolved from single-celled organisms without a backbone. Dana has a portfolio of 8 securities, each with a market value of $5,000. The current beta of the portfolio is 1.28 and the beta of the riskiest security is 1.75.

Transport (ER) Because of genetic variation, a species of beetle has two different body colors, red and green. This species exists in a grassy environmentthat's mostly green. A new species of bird that eats these beetles enters the area. Arrange the steps of natural selection in the correct order.Green beetles and red beetles exist in theenvironment.Green beetles pass on their color trait tofuture offspringBirds that eat the beetles move into theenvironment.Red beetles are eaten by birds, but greenbeetles aren't eaten.The entire population of beetleseventually becomes green in color.
