Answer: They may be prokaryotic is false.
Explanation:
Protists are eukaryotic organisms i.e they have membrane bound organelles and Nucleus. They are neither plants,animals or fungus. Protists have many form of nutrition and they may be aerobic or anaerobic.
Some protists photosynthesized like algae while others are heterotrophs
They may be unicellular or multicellular.
Some protists have cell walls while others don't.
Blood, a fluid connective tissue, provides a transport system within our body for oxygen and other important substances. Cartilage provides strong support and connection for our skeletal framework. And the function of bones is to support and protect soft tissues and organs in our body.
AnsweR:
Rough endoplasmic reticulum.
Explanation:
The endoplasmic reticulum is a member of the endomembrane system and is present as a continuation of the nuclear membrane. They are divided into the rough endoplasmic reticulum and smooth endoplasmic reticulum.
Rough endoplasmic reticulum has ribosomes on its surface and is responsible for the synthesis of secretory proteins. Smooth endoplasmic reticulum synthesize lipids.
Therefore cells that intensely biosynthesize secretory proteins like neurons, white blood cells have a greater amount of rough endoplasmic reticulum than another cell of the body.
Answer:
Evolution of species over a long duration happens due to adaptive learning of organisms in new environments. If the organism is flexible in different physiological environments, it will evolve. The metabolic processes change according the environment to an extent. Like breathing at a high altitude when Oxygen content is less.
Answer: A, excessive pollution decreases a communities access to affordable clean water.
