Answer:
Nuclear magnetic resonance is a method of physical observation in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus.
Explanation:
Answer:
The correct answer is - The decomposers decompose dead algae and plants which take up most of the oxygen.
Explanation:
Eutrophication is taken place when there is a high amount of nutrients, minerals are present in a waterbody which allow algae to grow rapidly and cause depletion of oxygen due to the decomposition of dead organisms. There are the following stages in the eutrophication process:
- rapid growth of Algae and other plants
- due to algal bloom, the sunlight is blocked, and plants and organism start dying.
- The decomposers take up most of the oxygen by decomposition
- The animals start dying without oxygen
Answer;
Biophysics
Explanation;
-Biophysics is the study of physical phenomena and physical processes in living things, on scales spanning molecules, cells, tissues and organisms. Biophysicists use the principles and methods of physics to understand biological systems.
-It is an interdisciplinary science, closely related to quantitative and systems biology.
-The electrocardiogram is a diagnostic tool that is routinely used to assess the electrical and muscular functions of the heart. During an ECG, sensors that can detect the electrical activity of your heart are attached to your chest and sometimes your limbs.
Answer:
1- They have circular DNA, RNA and 70s ribosomes
2- They reproduce by binary fission
3- They can synthezise ATP
Explanation:
Mitochondria and chloroplasts are semi-autonomous organelles that are similar in many aspects:
- Both of them have a similar size with bacterias,
- Both of them have enzymes that synthesize ATP,
- Both of them have DNA, RNA, and 70s ribosomes, these last ones characteristic of prokaryotes. They are capable of synthesizing proteins. Their DNA is circular and double-stranded,
- Both of them reproduce by binary fission, as prokaryotes do.
Because of all of these characteristics, mitochondria and chloroplasts are suggested to be once free-living bacterias.
