Answer:
B) Functional magnetic resonance imaging
Explanation:
fMRI or Functional magnetic resonance imaging is the technique which is used to measure the neural activity in the brain of humans and other animals.
The technique is based on the concept that the activity in the neurons is coupled to the flow of the blood in the neurons. The change in the rate of blood flow to the region of neurons shows that that part of the neuron is activated at that time.
Therefore by measuring the changes in the blood flow, the technique scans the neural activities of the brain.
Thus, Optio-B is the correct answer.
Chromatin: is a complex made up of genetic material (DNA), wrapped in protein , such as histones,present in the cells of eukaryotes<span>.
</span>Chromatids :before the cell divides, the chromosomes are copied, and each chromosome consists of two segments in the form of bat, the chromatids. Each cromátide corresponds to a copy of one of the 46 strands of DNA in every one of my cells (sperm and eggs).
Chromosomes: are present in cells that are in the process of Division. In place of chromatin, we can observe in the nucleus, small bat-shapedbodies quite stained, easily visible when observed under a microscope<span>.</span>
hope this helps!
Water enters a plant through the root hair along the concentration gradient. From the roots cells water moves into the xylem. Xylem is the major water conducting tissue in the plants. The main driver of water movement in the xylem is the transpiration. Transpiration is the loss of water from the aerial parts of plant. in this way water moves up to the leaves where water is used in the photosynthesis.
Answer:
Ecosystems are influenced by both biotic and abiotic factors. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.
