Greenhouse gases are REALLY bad for the environment and one of the major cause of global warming. Greehouse gases can stay lasting in the air for 20 to 200 years.
Answer;
-All of the above,
Genetic research and testing includes; the Human Genome Project, gene therapy
, and genetically engineering drugs.
Explanation;
-Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder.
- Genetic research is the study of human DNA to find out what genes and environmental factors contribute to diseases. It is concerned with the study of the role of genes in traits such as the development of disease. It has a key role in identifying potential targets for therapeutic intervention and also in understanding genetically based variations in response to therapeutic interventions.
A is the answer hope i could help
Answer:
Following statements are correct
A graded potential has a threshold Graded potential amplitudes decay over distances
Graded potentials can summate in space and time
Graded potential amplitude increases with stimulus strength
Explanation:
Graded potential is generated in a neuron when ions enter or exit through the ligand gated channels. In general, this potential decreases with time before reaching axon. Signals that reach the graded potential, determine whether the amplitude of the potential will reach the threshold and hence causes action potential. Graded potential travel only over a short distance and is either depolarization or hyperpolarization. Their strength reduces with time as the charged ions move out of the membrane. They summate temporally or spatially
Graded potentials spread by passive means i.e spreading electronically to neighboring membrane regions.
Hence, the correct statements are
A graded potential has a threshold Graded potential amplitudes decay over distances
Graded potentials can summate in space and time
Graded potential amplitude increases with stimulus strength
