Dr. Charles is using fMRI when she uses strong magnets to track changes in the brain's blood-oxygen levels.
Functional magnetic resonance imaging or (fMRI) is a techique used to measure brain activity by detecting changes associated with blood flow. When an area of the brain is in use, blood flow to that region will increase.
Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.
Definition: the principles that govern heredity were discovered by a monk named Gregory Mendel in the 1860,s on of these principles, now called Mendel law of segregation states that all pairs separate or segregate during gamete formation and randomly unite at fertilization <span />
Fermentation doesn't need oxygen in its process while respiration needs oxygen.
Fermentation is also known as anaerobic respiration and respiration is known as aerobic respiration.
Answer: adenosine triphosphate (ATP) - the high energy chemical compound with three phosphate groups that provides energy for all other cell activities
endocytosis - when cells engulf or ingest substances
cellular respiration - chemical reactions in plants and animals that break down food molecules into energy (ATP)
movement of particles or molecules from higher concentration to lower concentration - diffusion
when cells expel or get rid of substances from within- exocytosis
a solution that has a higher salt concentration than the salt - hypertonic
the relatively constant state in the internal environment of an organism - homeostasis
Explanation:
Adenosine triphosphate or ATP is the energy currency that is required for providing energy for metabolic functions and activities in the body.
Endocytosis can be defined as the process through which a cell engulfs another cell or substances to get rid of them.
Cellular respiration can be defined as the process through which the food in the organisms is oxidized and broken into parts to release energy.
Diffusion involves the movement or transfer of gas, liquid, and solid particles from a region of higher to lower concentration without the requirement of semi-permeable membrane.
Exocytosis is a process in which the cell releases those substances that are required by the cell.
Hypertonic is a solution that has more solute concentration than solvent concentration.
Homeostasis is a tendency to maintain constancy in the internal environment of body in relation to changes occurring in the surrounding.
