Answer:
The correct answer is: a. Maggots do not arise spontaneously, but from eggs laid by adult flies.
Explanation:
- The meat in the open jars can be directly accessed by the adult flies for consumption. While accessing the food, some of these adult flies can lay egg into the jars which hatch to give rise to new maggots.
- The meat in jars closed by a gauze is exposed to the air but cannot be accessed by the adult flies as the flies are prevented from entering into the jar due to the presence of the gauze. As a result of this the flies do not consume meat, nor do they lay eggs and so no maggots will appear in this jar.
Wind and water carry sediments and deposit them in layers usually in a lake or ocean bottom. The process that turn sediment into solid rock are compaction and cementation. The processes of compaction and cementation together are known assedimentation.
Answer:
Option (b).
Explanation:
Melting temperature may be defined as the temperature at which the DNA strand melts. The melting temperature depends on the Guanine and cytosine content of the DNA.
The thymine binds with Adenine with two hydrogen bonds whereas cytosine binds with guanine with three hydrogen bonds. More energy is required to break the guanine cytosine bonds and they have high temperature. The second strand 5'-ACGGCTACG-3' contains more GC content and hence have high melting temperature.
Thus, the correct answer is option (b).
There is poor ingestion of prescribed medications in the elderly and this can lead to greater potential for medication problems due to polypharmacy. They are being provided with a lot of medications. Thus, resulting into diarrhea, disorders in the kidney or bladder as well as obesity and allergies.
Rudolf Virchow was the scientist whose revolutionary theory, contending that cells only arise from other cells, challenged the theory of spontaneous generation. It is a site of steroid synthesis, drug detoxification, and lipid metabolism.
What is metabolism?
- Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body's cells that change food into energy.
- Our bodies need this energy to do everything from moving to thinking to growing.
- Specific proteins in the body control the chemical reactions of metabolism.
- The chemical processes that let you stay alive are an example of metabolism.
- The rate at which you burn fat and calories you consume is an example of metabolism. The processing of a specific substance within a living cell or organism.
