Colder temperatures that last for a short period of time such as 3-4 days.
Answer:
Must have lived before.
Explanation:
For an organism to be classified as once living, an object must have been part of a living organism or is now dead. When a flower is plucked from a plant it is hard to distinguish between when it is considered alive and when it is now considered once living. An example of a nonliving object is an apple or a dead leaf.Apr 22, 2013

Then the submerged aquatic plants will note be able to receive light for photosynthesis. then those submerged aquatic plants will not have food/nutrients to survive, hence die. aquatic animals will not receive sufficient oxygen from those submerged aquatic plants, hence die also.
decomposes will breakdown all dead organisms to release carbon dioxide, and also deplete oxygen concentration during decomposition process.
eventually, habitat is rendered not livable. only the algae continue to proliferate uncontrollably at the water body surface.
Answer:
False
Explanation:
Remember Q=MCAT
Specific heat wouldn't be effected, rather, the energy necessary to change the temperature would.
The BRCA 1 and BRCA 2 genes are two genes that are sought in the genetic study of an individual in order to seek a predisposition to breast cancer (in women and also in men).
The genes of Tay-sachs, are researched in order to diagnose or eliminate Tay-sachs disease.
The first difference lies in the goal of the research: for the BRCA (screening) genes, a predisposition is sought and for the Tay-sachs genes, it is sought to confirm the disease.
The second lies in the technique used:
The first step in the study of these genes is to isolate and replicate them. The best technique for this is the PCR (polymerase chain reaction). By using primers we can amplify the gene we want. So the primers used in BRCA and Tay-Sachs research are necessarily different.
