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.

ASAP Determine whether the statement is true or false and why. “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to a different period in time becoming more human-like the closer to the present they are, showing a clear evolution into humans.”
A. False, it should read “We have discovered no series of humanoid fossils that are similar to humans, showing a clear lack of any transitional fossils as evidence of human evolution”
B. True
C. False, it should read “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to a different period in time becoming less human-like the closer to the present they are, showing a clear evolution away from humans.”
D. False, it should read “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to the same period in time, showing that many human-like species existed at once, but all went extinct.”

Answers

The statement is true.

Human evolution is a scientific term that refers to the process of biological evolution of the human species from its ancestors to the present.

The current knowledge of human evolution is the result of the convergence of various sciences such as:

Genetics.Physical anthropology.Paleontology.Geochronology.Archeology.Linguistics.

The results of various studies relate the current human species as a result of multiple evolutionary processes of hominimus species, ardipithecus, australopithecus, and homo that through time improved different aspects until reaching the human species that exists today.

According to the above, what is described in the fragment presented is true because it presents a correct version of what happened in human evolution. Meanwhile, options A, C and D are incorrect because they do not present correct information regarding human evolution.

Answers

Nucleic acid, just know nucleic acid is made up of nucleotides

When many nucleotides link together, they form a biomolecule responsible for storing genetic information called nucleic acids. Thus, the correct option is B.

What are Nucleotides?

Nucleotides may be defined as the basic unit of the polynucleotide chain of nucleic acids such as DNA or RNA. Each nucleotide is composed of three components. They are as follows:

A nitrogenous base.A pentose sugar (ribose in the case of RNA, and deoxyribose in the case of DNA).A phosphate group.

Nucleotides are the monomers of nucleic acids. Each nucleotide is joined together by covalent bonds known as phosphodiester linkage. This linkage is present between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar of next nucleotide.

Therefore, nucleic acids are formed when many nucleotides link together which are responsible for storing the genetic information.

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

Answers

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.
