Why do you think species remain in a stage of stasis? A. A stable ecological niche leads to absence of selection pressure, which in turn causes species to remain unmodified or in stasis.
B. An unstable ecological niche leads to various selection pressures, which in turn causes the species to remain in a stage of stasis.
C. A stable ecological niche leads to various selection pressures, which in turn causes species to remain unmodified or in stasis.

Answers

Answer 1

Answer:

I believe that species remain in a stage of stasis because they have completely adapted to the environment they are in and are able to live successfully without any evolutionary changes. The species has all the necessary traits in order to survive.

Answer: A) A stable ecological niche leads to absence of selection pressure, which in turn causes species to remain unmodified or in stasis.

I hope it helps, Regards.

A scientific model is easier to interpret and understand when it includes the main parts or processes, rather than every detail of every part or process. is this true or false

Answers

This is true, because extra detail and collateral information begets you to digress and eventually lead some people astray because they lose interest. You'd rather be straight to the point and give key facts about your model instead.

Which structure is represented by the letter C?Choose 1 answer:

(Choice A)
Chloroplast

(Choice B)
Vacuole

(Choice C)
Nucleus

(Choice D)
Mitochondria

Answers

C! I just did cells and their organelles!

Final answer:

Determining which cell structure is represented by 'C' isn't possible without a diagram. However, the listed structures include the Nucleus, Chloroplast among others, with each playing a significant role in cell functionality.

Explanation:

Without the specific diagram, it's difficult to accurately determine which structure is represented by the letter C. However, given the options, the four choices, A) Chloroplast, B) Vacuole, C) Nucleus, and D) Mitochondria, are all essential components to a cell's functionality. The Nucleus acts as the control center of the cell, containing DNA and regulating gene expression. The Chloroplast, on the other hand, is unique to plant cells and is the site of photosynthesis where sunlight is converted into energy for the cell.

The characteristics of all organisms and viruses are determined by the instructions carried in _______. A. hydrogen bonds B. nucleic acids C. sugar bases D. phosphoric acids

Answers

the correct answer is B. the information that decides the characteristics of all organisms are contained in their nucleic acids. Nucleics acids are DNA and RNA. DNA have genes that code for proteins which are responsible for the structural and functional characteristics of organisms. DNA is transcribed into RNA and RNA is translated to proteins. Therefore information that is in these nucleic acids determines all the characteristics of organisms

The characteristics of all organisms and viruses are determined by the instructions carried in nucleic acid.

Further Explanation:

Nucleic acid is an information molecule that plays an important role in the storage and transmission of hereditary information. They are polynucleotide that means it is composed of a long chain of molecules. It is composed of a series of nucleotides that are identical to each other. It is the primary component of the DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA is the double-stranded genetic material that is present in each living cell. RNA is a single-stranded genetic material that helps in many cellular activities such as protein synthesis.

DNA acts as a master blueprint for life. It is present inside all living organism both eukaryotes and prokaryotes. It is present in bacteria and most viruses. RNA is the genetic material that is present in the certain virus. The genetic material helps in determining the class or species of the organism.
