To clearly view the morphology of the prokaryotes, one needs a microscope with higher resolution i.e magnification of ×100. Use of oil for this purpose is important because it reduces the refraction of light as it travels from air to glass. this process increases the resolution of the microscope making it possible to view morphology of bacteria.

Answer:
The correct answer is - 1. true, 2. true, 3. false, and 4. true.
Explanation:
1. Rod cells are the photoreceptors present in the retina that are hyperpolarized not depolarized in dark due to sodium ions efflux.
2. Depolarisation of the bipolar cell of the retina by glutamate release by rods and cones.
3. The adaption according to the light is known as a light adaptation which takes place due to a large part of photochemical in both rods and cones which is reduced to retinal and opsins.
4. when the light reaction takes place retinal converted to opsin
Answer:
Hot, humid temperatures than today.
Explanation:
- The Carboniferous period is was a geologic period that spans about 60 mn years ago and is named for the coal-bearing period. In the beginning, the climate was warm and hot had temperature about 20 degrees, but in the middle cooling occurred and the temperature was about 12 degrees.
- The cooling and drying of the climate lead to the Carboniferous rainforest. The planet was much hotter and more humid than we see it today and had more carbon dioxide and greenhouse gases in the atmosphere than exists today.
Answer:
Seen on the explanation.
Explanation:
Glandular tissues are a mixture of both endocrine (ductless, hormones are secreted directly into the blood) and exocrine (have ducts, hormones are secreted into surfaces) glands.
The pancreas and salivary glands are both exocrine glands although the pancreas has an endocrine function via the islets of Langerhans, both aid in the digestion of food.
The pancreas lacks striated ducts and the intralobular duct is similar to the intercalated duct of salivary glands. It often has a collapsed lumens and the cells are cuboidal with little cytoplasmic staining in contrast to acinar cells.
The pancreas can also be distinguished from the parotid gland by the presence of the pancreatic islet (islets of langerharns) which has an endocrine function.
