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.

Answer:
A warm welcome to all present here. Today I am going to give a speech on deforestation. Deforestation is the process of cutting down the forest, without replanting them again.

Can bacteria break down plastics?
Give reason
Answer:
Yes, bacteria can break down plastics because they break down the molecules of the plastics into their original building blocks and by secreting an enzyme which “eats” the chemical bonds in the chain, the molecules are broken down into their smaller components.
how can so much DNA could fit inside a bacterial cell.
Answer:
The reason so much DNA could fit inside a bacterial is because the DNA are double-stranded, looped, coiled, and foleed into the cell. The DNA is tightly fitted around the nucleus.

Which method gives the actual age of a fossil in years?
Answer:
Radiometric dating methodsExplanation:
Researchers use a clock to estimate the date a rock or fossil was produced in order to ascertain its age. Radiometric dating methods, which are based on the natural radioactive decay of specific elements like potassium and carbon, are widely used by geologists to date ancient events.

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.

Complete question:
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.
Group of answer choices
A) behavioral . . . prezygotic
B) mechanical . . . postzygotic
C) temporal . . . prezygotic
D) gametic . . . postzygotic
Answer:
A) behavioral . . . prezygotic
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
There are different types of reproductive barriers.
Pre-copulatory o pre-ziygotic:
Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.
