The genetic diversity of a rocky shore habitat declines precipitously as the climate warms, causing a decline in the number of species present. The decline of species along the rocky shore negatively affects the entire region, including bird populations and shallow offshore habitats. This scenario is best described as a change in the region's ______________________.
The scenario that is best described here is a change in the region's BIODIVERSITY. This measure (biodiversity) indicates the genetic/phenotypic variability found in a region.
Biodiversity refers to the genetic and phenotypic variability of the organisms found in a particular geographic region or the variety of life on the Earth's planet.
Biodiversity can be used to indicate the amount of variation at different levels (i.e., genetic, species, and ecosystem levels).
The different types of animals, plants and microorganisms that live in a forest represent an example of biodiversity.

why are antibiotics not effective against viruses?
Answer:
Viruses are different to bacteria; they have a different structure and a different way of surviving. Viruses don't have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.

Estimating the weight of a dinosaur using only bones is difficult. Another way is by using scale models. The density of a dinosaur is scaled based on the average density of what living animal
Given what we know about the methods used by scientists to estimate the weight of a dinosaur, we can confirm that the density of a dinosaur is scaled based on the average density of the common crocodile.
Scaling the density of an extinct animal based solely on bones can be a daunting task. Since the bones themselves do not offer much information on which to base such a calculation, scientists are often forced to rely on other estimations. One such example is the bone scaling method.
This method relies on the genetic relationships shared between the dinosaur and current-day living animals. This offers the ability to compare the dinosaur to the known body mass of a modern-day living animal. The animal most commonly used is the crocodile, however, though this method can provide the scientists with a degree of accuracy, it lacks precision.

Onion root tips contain cells that are constantly dividing. Why was it important to use the onion roots tips to observe chromosomes during mitosis rather than a cell from another part of the plant?
a. Because cells in the leaves do not have DNA or chromosomes.
b. Because chromosomes only form during mitosis, one part of cell division
c. Because root cells are naturally purple, so you can see the chromosomes
d. Because cells in the leaves only divide, but do not undergo mitosis.
Explanation:
the answer to your question is A
Onion roots are used to see mitosis because of rapid growth at the onion tips and at the stage of mitosis,leaves of the plants has division in the cells but there is no mitosis. the correct answer is option D.
What is the significance of mitosis ?The significance of mitosis is that in the stage the chromosomes are paired and the pairing of this homologous chromosomes makes the chromosomes visible at the equatorial plate.
Leaves do not undergo cell mitosis as they do show the cell division from various types of tissues but the mitosis is absent and the root cells show rapid division in the lateral sides and because of roots being the active site of division, these are considered more to see mitosis happening.
Thus, mitosis being absent in leaves takes the roots to be considered option.
