Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.
The first one is epidermis, the second one is the dermis i believe, I hope this helps
There are various imaging techniques in collecting information about the brain and its adjacent structures. To enumerate, there are the cranial ultrasound (for children with cranial sutures that are not closed yet), cranial CT-scan, cranial MRI, brain PET scan, and cranial functional MRI. Only the brain PET scan and cranial functional MRI can collect information about the brain function by detecting fluorodeoxyglucose (FDG) in the brain as this lights up in functional areas of the brain in PET scan; and by detecting brain activity through changes in blood flow in cranial functional MRI.
<em>While it is not an imaging technique, electroencephalogram or EEG can detect brain function.</em>
The products of photosynthesis, oxygen and glucose, are the reactants of cellular respiration. The products of cellular respiration, carbon dioxide and water, are the reactants of photosynthesis.
Answer:
The International System of Units (SI, abbreviated from the French Système international (d'unités)) is the modern form of the metric system and is the most widely used system of measurement.
Explanation:
The seven SI base units, which are comprised of:
Length - meter (m)
Time - second (s)
Amount of substance - mole (mole)
Electric current - ampere (A)
Temperature - kelvin (K)
Luminous intensity - candela (cd)
Mass - kilogram (kg)
