Answer:
Archaebacteria are primitive, single-celled microorganisms that are prokaryotes with no cell nucleus. Each archaea has the ability to live in very severe environments.
Archaebacteria are one of the six kingdoms of life: plants, animals, protists, fungi, eubacteria and
Gel electrophoresis is the movement of charged particles in a fluid or gel under the influence of an electric field. Results of this technique can be interpreted to find out if someone carries a certain gene or not.
NOTE: the steps of the signal transduction pathway to be arranged is in the attached file.
Answer:
The correct signal transduction pathway in order from the releasing of glucagon into the blood to the promotion of glycogenolysis includes:
- Glucagon binds extracellulary to G- protein coupled receptor.
-G protein releases GDP and binds FTP
-Activated G protein activates adenylate (adenylate) cyclase.
-Adenylate cyclase converts ATP to cAMP.
-Cyclic AMP activates protein kinase A
- phosphorylase kinase phosphorylates glucogen phosphorylase, an enzyme needed for glycogenolysis.
Explanation:
As carbohydrates from food consumed is digested, it's end product, the glucose, is assimilated into the cells for energy production through the help of insulin in a process called glycolysis. Excess of glucose is stored in the liver as GLYCOGEN.
In cases where there is reduced sugar in the blood (hypoglycemic state) another pathway (known as glycogenolysis through
GLUCAGON hormone) is initiated to elevate the concentration of glucose in the blood.
Answer:
The correct answer is "altering the equilibrium of ecosystems".
Explanation:
Ecosystem have a very complex and sometimes intricate equilibrium. Each species in an ecosystem have a role in the food chain, therefore, if humans affect the behavior of one species, undoubtedly, another species will be affected. In this case, insect populations are increasing as a result of birds modifiying they migratory behavior due to the presence of discarded food in the landfills. Most likely the increased insect populations will affect the plants population as well, creating a series of events that alter the equilibrium of the ecosystems.
An area that was covered by a glacier
Primary succession is a method of bringing about fertility in infertile land that can not be cultivated. This method usually involves plant species known as "pioneer species", that do not rely heavily on soil nutrients but add nutrients to the soil. The land under the glacier is likely to be void of nutrients and infertile, so primary succession will be needed there the most.
