The right answer is B) Specialized tissues come together to create the stomach, which is an organ.
* Cells linked to each other form a set called tissue. The cells composing a tissue are not all identical, but they work together to provide a specific function.
* Each organ is a recognizable structure (eg, heart, lungs, liver, eyes, stomach) that provides a specific function. An organ consists of different types of tissues and, therefore, different types of cells.
The stomach is a thoraco-abdominal organ, located in the abdomen and in contact with the chest wall.
The stomach is a dilated segment of the digestive tract located between the esophagus and the duodenum. Its main function is to turn the food bolus into a mixture called gastric chyme.
The stomach is composed of two parts, two sides (anterior and posterior), two edges (small and large curvature) and two orifices (the cardia, upper orifice, and the pylorus, lower orifice).
Answer:
Photosynthesis consist of two types of reaction 1 light dependent reaction 2 light independent reaction or dark reaction.
Explanation:
light dependent reaction
light dependent reaction or light reaction occur in the thylakoid of granum of chloroplast.During light reaction light energy is absorbed by various pigments of the photosystem and is finally converted into chemical energy.
During light reaction water is split in presence of sunlight to form H+ and OH- ions.The OH- ions releases electron.The released electron is then transported through various electron carriers resulting in the formation of ATP molecule by cyclic photo phosphorylation and NADPH by noncyclic photophosphorylation.
Light independent reaction
Light independent reaction or dark reaction occur in the stroma of chloroplast.The ATP and NADPH that is formed during light reaction is used as 3:2 ratio for per molecule of glucose production.
Answer:
In the electromagnetic spectrum, the visible spectrum is the part, which is perceptible to the human eye. The electromagnetic spectrum in this array of wavelengths is known as simply light or the visible light. A general human eye will react towards the wavelengths in the range between 380 to 740 nm. A human eye sees the sky as blue that comes in the wavelength 490 nm because of the scattering of the visible light by the particles in the atmosphere. This concludes that 490 nm is the sole wavelength, which is reaching the eye.
