IrinaK [193]

Answer:

The correct answer is "The eggs must have internal membranes".

Explanation:

Amniotes are animals that have adapted to reproduce putting eggs on land (reptiles, birds or mammals). The eggs of amniotes have internal membranes that let gases but not water pass through. This characteristics allows the embryo to breath inside the egg, and allow the egg to not dry out on land. Therefore, the eggs of the new species of animal must have internal membranes in order to allow its reproduction on land.

Do the information given and the map best describe adaptive evolution, convergent evolution, or coevolution? Explain your respon
miss Akunina [59]

Hi, the given question is incomplete, it is missing a diagram, the diagram is given in the attachment below,

Answer:

The correct answer is adaptive evolution.

Explanation:

Based on the given information, it is clear that it best illustrates the phenomenon of adaptive evolution. It is known that different species of finches exhibit an ancestor, which is common, however, all the species have shown adaptation based on the kind of food they are getting within their surroundings.  

The evolutionary modifications that arise by getting adaptive to the specific environment are termed as adaptive evolution. These changes arise due to the phenomenon of natural selection, which further enhances the tendency of reproducing or survivorship after going through some of the challenges presented by the surroundings.

During aerobic respiration, the energy within the bonds of a glucose molecule is released in small amounts in a step-by-step, en
Rus_ich [418]

Answer: In this process, the energy released in form of ATP (Adenosine triphosphate) is used to POWER BIOCHEMICAL PROCESSES.

Explanation:

Aerobic respiration is the process by which living organisms breaks down glucose molecule to release energy. Oxygen is used for this process that's why the name aerobic.

Aerobic respiration releases energy within the bonds of glucose step by step in an enzyme controlled reaction. The stages of these processes includes:

--> Glycolysis: In this stage, glucose molecules are split to produce two molecules of ATP and two molecules of NADH (another energy carrying molecule).

--> Krebs Cycle: this is the second stage which occurs in the mitochondria of cells. The 2 ATP molecules generated from glycolysis is used to produce two more ATP, 8 more NADH and 2 molecules of FADH. This makes it a total of 16 energy molecules ( including 2 molecules of ATP from glycolysis).

--> Electron transport chain: this is the last stage of aerobic respiration which takes part at the inner member of the mitochondria. Electrons are transported from molecule to molecule down an electron-transport chain. Some of the energy from the electrons ( NADH and FADH from kreb cycle) is used to pump hydrogen ions across the membrane, creating an electrochemical gradient that drives the synthesis of many more molecules of ATP. As a result 32 more ATP are generated.

In conclusion, a total of up to 36 molecules of ATP from just one molecule of glucose in the process of aerobic respiration which are used to power biological processes.
