Biofeedback headsets measure your brain waves, using EEG. They're small bands that sit easily on your head and measure activity through sensors
Through reabsorption of carbonic acid in the tubule or through ammonia
The answer is a generalist, able to be flexible in major dimensions of its niche. In addition, as coyotes extended their variety they also extended their set menu. As soon as omnivores restricted by the grassland fauna of rabbits, mice, and insects they now resourcefully consume the whole thing from small mammals and birds to livestock and animals, bounties and vegetables, meat and trash. Their environment has also extended to contain a collection of natural and social altered environments as well as the woodlands, the savannahs and the swamplands, the parks and the golf courses, the suburban backyards, and the urban expansions.
B) Bacteria can be treated with antibiotics, viruses cannot.
Antibiotics have no target when dealing with viruses. Antibiotics work on bacteria because it targets the growth machinery in bacteria. Viruses are found inside a human cell and reproduce by inserting their DNA into a human cell. There are antivirals and vaccines out there for viruses. Our body’s immune system fights against viruses with antibodies!
Answer:
All of these choices are correct.
Explanation:
Cell cycle is the process of growth and division of cell. It comprises of interphase and mitosis. In interphase the cell grows, replicates its genomic content and prepares itself for division. In mitosis the division occurs.
Cell cycle is controlled by a group of kinases called as Cyclin dependent Kinases (CDKs). They act by phosphorylating their substrates. They are of various types like Cdk1, Cdk2, Cdk4 etc. They become active when they bind to a regulatory protein called cyclin. They are also of various types like Cyclin A, Cyclin B, Cyclin C etc. Level of cyclin and corresponding CDK increases and decreases according to the stage of cell cycle. For example in S phase of cell cycle concentration of cyclin A and E shoots up. CDK2 is able to bind to these cyclin molecules and hence it becomes active.
Cell cycle has major checkpoints where the condition of cell is analysed before it proceeds to the next stage of cycle. If any abnormality is detected, repair mechanism is activated or the cell is killed. Checkpoints do not allow cell cycle to proceed in damaged cells.
p53 is a tumor suppressor protein which can halt cell cycle when it detects some abnormality in cell. It usually acts in G1/S checkpoint (before the DNA replication starts in cell) and G2/M checkpoint (before the cell division begins). Hence, all of the above statements are true.
