Explain how homologous structures are used as a source of evidence to infer evolutionary relationships between modern and fossil organisms

Answers

Answer 1

Answer:

Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

Explanation:

Answer 2

Analogous structures demonstrate that identical selective pressures might result in similar adaptations, whereas homologous structures indicate evidence for shared ancestry.

What are analogous structures?

In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.

While comparable structures demonstrate that similar selective pressures can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features).

Therefore, homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

1. Describe the structures of the chloroplast where photosynthesis takes place.

2. What would happen if the stomata of a plant leaf were glued shut? Would that plant
be able to perform photosynthesis? Why or why not?

3. What are the reactants needed to perform photosynthesis? The products?

4. What happens to the products of photosynthesis?

Answers

Answer:

In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.

The plant leaf would not be able to perform photosynthesis. The leaf needs to have its chloroplasts facing the sun, so that they can absorb the sunlight to perform photosynthesis.

During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6). The oxygen will leave the plant through the stomata and enter Earth's atmosphere.Explanation:

alveoli

Explanation

During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Required Answer :-

The exchange of gases takes place in the alveoli.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Additional information :-

Alveoli are microscopic air sacs.

They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.

Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.

CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.

Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.

Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.
