Which of the following statements support(s) the theory of the endosymbiotic origin of chloroplasts?
Chloroplasts have their own DNA, separate from the DNA in the nucleus.
They contain their own ribosomes to translate and make proteins.
They self-replicate and reproduce on their own.
They don't have similarities to photosynthetic prokaryotes.
I only
I and II only
I,II, and III
I, II, and IV
Answer:
C
Explanation:
According to the endosymbiotic idea, a few eukaryotic cells' organelles were previously prokaryotic microorganisms. Chloroplasts and mitochondria divide by binary fission. Therefore, option (C) is correct.
What is Endosymbiotic Theory ?According to the endosymbiotic theory, eukaryote cell organelles like chloroplasts and mitochondria descended from separate bacteria that eventually developed symbiotic relationships with other cells.
Both mitochondria and chloroplasts have circular, single-stranded DNA in addition to not having histones. Prokaryotes are the only organisms that have single-stranded, circular DNA. They contain their own ribosomes to translate and make proteins. These qualities would enable the mitochondria and chloroplasts to thrive on their own, supporting the endosymbiosis theory.
Therefore, option (C) supports the theory of the endosymbiotic origin of chloroplasts.

write a short note on akaryotic cells
Answer:
Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms. Protozoa, fungi, plants, and animals all have eukaryotic cells. ... They can maintain different environments in a single cell that allows them to carry out various metabolic reactions
Answer:
Explanation: Akaryocytes, also known as akaryotes or acaryotes, are cells without a nucleus. The most common type of akaryocytes are viruses. The name is derived from the Greek prefix "a-", meaning "without" and the Greek "karyo-", meaning "nut" or "kernel". ... This cell biology article is a stub.

Some of the constants could be...
- Sunlight
- Water
- Room temperature
- Hours of light
- Soil quality

What is responsible for the red tide phenomenon? It is a phenomenon that usually coincides with storm surges; the name comes from the red kelp that often washes ashore as a result of rough weather. Red tide occurs in patches of water where certain species of dinoflagellates flourish. They are so abundant that the water becomes discolored and takes on a red hue. Red tides occur once a year and in accordance with the lunar cycle. The water appears red as a result of reduced levels of photosynthetic pigmen
Answer:
Red tide occurs in patches of water where certain species of dinoflagellates flourish.
Explanation:
Red tides refer to the noticeable microalgae proliferation that can be recognized for being a big spot in the sea of a characteristic coloration. This phenomenon is caused by two microalgae groups: diatoms and dinoflagellates, both part of phytoplankton.
Red tides occur when certain environmental factors -such as temperature, light, nutrients availability, ph, etcetera- favor the overproduction of these organisms. These species produce toxins that turn to be dangerous for other animal species that feed on them.
Because these microorganisms produce pigments, their accumulation on the sea surface can be noticed as reddish, brown, or greenish color spots of variable extension.
