<span>The question is asking us to choose the order of increasing complexity and the correct answer is
(3) organelles → cells → tissues → organs. Organelles are parts of cells, for example a mitochondrium is an organelle. Many cells form tissues and tissues form an organ. Many organ for an organism, for example, a human being is an organism - that's the whole animal or plant. </span>
Rats account for a decent amount of biomass globally. They are intermediate predators, eating a lot but also being eaten. If they went extinct, they would stop eating many insects and seeds / fruits -- the former would gain significantly in population, and the latter would lose some of their pollination. Both factors would harm the viability of at least some species of plants, by adding to plant eaters (insects) and reducing plant reproduction. Rats' predators would also suffer if they went extinct. The primary predators are birds of prey, such as hawks and owls. However, other animals such as skunks, foxes, weasels, coyotes, and even wolves eat rats. For predators in marginal environments, the loss of such a food source could drive them out of a habitat area.

Just took this test plz mark brainliest so i can help others like you and reach higher goals
Most sponge body plans are slight variations on a simple tube-within-a-tube design. which of the following is a key limitation of sponge body plans? sponges lack the specialized cell types needed to produce more complex body plans. the reliance on osmosis/diffusion requires a design that maximizes the surface area to volume ratio of the sponge. choanocytes must be protected from the hostile exterior environment. spongin cannot support heavy bodies.
The answer is: the genetic code is shared by all organisms.
Explanation: Genetic engineering means changing the DNA sequence by adding DNA from another source. We can easily insert DNA into another organism/ bacteria because they share the same genetic code/base paring rules. Genetic code include: Adenine with thymine and cytosine with guanine.
Hope this helped! :)
