Density = mass / volume. therefore, something with a greater density either has a larger mass or a smaller volume. Think of density as how compressed something is: more "stuff" (mass) or a smaller "space" (volume) will make whatever that material is more compressed.
Answer:
1: Organism
2: Population
3: Community
4: Ecosystem
(the word bank literally gave it away)
Explanation:
You can see that box 1 is next to 1 animal, so it's an organism.
You can see box 2 is next to a group of the same animals, so it's a population
You can see box 3 is next to a small group of multiple species, so it's a comunity
You can see box 4 is next to a fully functioning group of species, so it's called an ecosystem
The answer is
Recombination is an exchange between homologous chromosomes (e.g. chr 1 from mom x chr 1 from dad). Since it usually happens during meiosis, these strands are later separated. Recombination can be unequal or equal, but it's usually equal, and unequal crossovers are generally quite small (but a common source of addition/deletion).
Reciprocal translocation refers to an exchange between different chromosomes (e.g. chr 1 x chr 2). It is considered a large scale mutation (resulting in a large addition to one chromosome, and a large deletion in another).
<span>bones and footprints preserved in stone are examples of fossils. Fossils hardened animal remains such as shells, bones, and teeth.</span> That is the best i can come up with. Hope it helps any.
In the course of recent years, 60 percent of all biological community administrations have declined as an immediate consequence of the change of area to the creation of nourishments, powers and strands. This ought to shock no one, say seven of the world's driving ecological researchers, who met to all things considered study the pitfalls of using markets to prompt individuals to assess the natural expenses of their conduct and arrangements. We are getting what we pay for.
