Answer: b
An inherited modification of structure or function that allows an organism to survive and reproduce in its environment.
Explanation:
Adaptation helps an organism to become better suited to survive and reproduce in its environment. It is change in an organism's structure or behavior.
Change in physical features of an organism is considered as structural adaptation. Example- fur in bear
Change in the way an organism does things to survive is called behavioral adaptation. Example- bird calls and migration from one place to another.
Adaptation is an essential feature that helps an organism to better servive in the environment. In case, an organism fails to adapt to changes in its environment, its immune system becomes weak and fails to work. This threatens its life and it becomes ill. This may also result in its death.
B) The water molecules remain together. The salt molecules break apart.
Step-by-step explanation:
When the salt is being place upon the water, the sodium in salt becomes attracted to the water molecules. Both H20(water) & NaCI (salt) start to become drawn, during this reaction. This causes water to remain together, while the salt is broken apart and dissolves. Hope this helps!
Answer:
d) A constitutively active mutant form of PKA in skeletal muscle cells would lead to an excess in the amount of glycogen available.
Explanation:
This occurs in the process of Glycogenolysis. The process involves breaking down of glycogen to glucose -1- phosphate and glycogen which helps in the release of glucose into the blood stream to prevent hypoglycemia(low blood sugar). The glucose-1-phosphate is later converted to glucose -6-phosphate. The latter enters the glycolytic pathway in which the reaction is catalysed by the enzyme phosphoglucomutase.
This homeostatic glucose regulation is regulated by the protein kinase(PKA)/ cAMP pathway in the skeletal muscles, the liver and the pancreas.
Answer:
Explanation:
mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.
FGF5 is a gene that is encoded in the DNA.
In developed nations people have more fast food options which lead to cardiovascular disease. As well as screen time all day since this is one of the factors of cardiovascular disease. Undeveloped nations don't have fast-food or television to watch all day, since they play outside.
