Scientific investigations often lead to the formulation of new scientific questions. The observations Charles Darwin made during his time aboard the H.M.S. Beagle prompted him to ask which question? Do living organisms change over time and, if so, how? Are the finches of the Galapagos Islands the same as those on the mainland? Can selective breeding occur in nature? Can the accumulation of gradual changes in a population lead to a new species over time?

Answers

Charles Darwin is known as the man behind the concept of natural selection - that some traits that give relative advantage would appear more and more often, eventually changing the species over time. The correct answer is thus the last one: "the accumulation of gradual changes in a population leads to a new species over time". It especially can't be the first option - we know that organisms chance over time (children become adults) - so we didn't need Darwin to realize that, this is somehting that people have understood for a long time. His discovery was connected to selective breeding, but his major insight was gradual evolution, not the breeding itself.

Charles Darwin observed that the accumulation of gradual changes in a population leads to a new species over time.

Further Explanation:

Scientific experimentations are the logical and practical procedures that determine the efficiency of a particular claim using scientific means. Charles Darwin was the one who gives the theory of evolution that occurred by natural selection. According to Darwin, evolution was descent with modification. There is a common ancestor between the species that changed over time and became new species. Natural selection is the reason why the population grows adapted for well suited to the environment over time.  

 

The pre-existing heritable variation in the group is the prime condition for natural selection to happen in the environment between the species. Natural selection is the process by which the well-suited organism in the population gets selected due to stress in the atmosphere thus evolving the species. In Darwin's book ‘The Origin of Species’, all these facts and information are mentioned, and the ideas of evolution and natural selection are well-reflected.

Which is the best definition of a prokaryotic cell? It has a cell wall but lacks a well–defined nucleus and organelles, and its cytoplasm doesn't have much structure.It contains a membrane–bound nucleus and organelles, and its organelles have specialized duties.
It contains a membrane–bound nucleus, a large central vacuole, a cell wall, a cell membrane, and chloroplasts.

Answers

Options:
it has a cell wall but lacks a well–defined nucleus and organelles, and its cytoplasm doesn't havemuch structure. - this is the correct one!


It contains a membrane–bound nucleus and organelles, and its organelles have specialized duties.
no!, this is false! prokaryotes don't have membrane-bound nucleus!

It contains a membrane–bound nucleus, a large central vacuole, a cell wall, a cell membrane, and chloroplasts.- no!, this is false! prokaryotes don't have membrane-bound nucleus!


so, for this we only needed to know that prokaryotes DON'T have a membrane-bound nucleus (and this is also perhaps their most important property)

Explain how the burning of the food calories in the burning of the wood are similar and how they are different

Answers

Answer:

The burning of wood and the burning of food calories produce carbon dioxide and heat. The calory burning gives energy to the body but in wood burning only wood becomes a carbon compound i.e. ash.

Explanation:

The burning of wood and the burning of calories release carbon dioxide and heat. In the body, oxygen breaks down the food calories and produces CO2 which release from the body by exhalation. The heat produced by food burning causes sweating. Oxygen also helps in burning of wood. In this way the food calory burning and wood burning are similar.  

In calory burning the complex food becomes simpler and helps in tissue metabolism. In wood burning atmospheric oxygen helps in burning, and they release other gases like carbon monoxide, nitrogen to the environment which is not happening in case of metabolism. The complete burning of wood results in carbon compounds. In calories burning excess energy is stored in the form of fat. Because food calories are nothing but energy derive from different food.

similarity: both burnings lead to energy production and both result in CO2 emission.
difference: food is burned in the process called cellular respiration. this process consists of a few certain stages preventing our body from heat shock.
