The answer to this question is 'convergent evolution'. Basically, this is when species of different lineages independently evolve similar functional features.
Development of wings is a classic example as this has independently evolved in insects, birds, pterosaurs, and bats.

How are living things organized from atoms to molecules

zhannawk [14.2K]

Answer:

The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

A list of the cell fibers from largest to smallest would read: 1. microtubules, intermediate filaments, microfilaments

Dahasolnce [82]

A list of the cell fibers from largest to smallest would read:

1. microtubules – is a microscopic tubular structure that is present in numbers in the cytoplasm of cells. These are usually aggregated to form complex structures.

2. intermediate filaments – are cytoskeletal components that is usually found in the cells of vertebrate species and other organisms like plants, fungi, unicellular organisms.

3. Microfilaments – are filamentous structures that can be found in the cytoplasm of eukaryotic cells and it will form part of the cytoskeletons. They are composed primarily of polymers of actin. But in cells, they usually interact with other proteins.

in experiment 1, which of the following factors was systematically changed so that its effects could be observed? A.light intens

Stels [109]

Explanation:

A.light intensity

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

At the compensation point, the rate of CO2 production by respiration matches the rate of CO2 utilization in photosynthesis- there is no net CO2 production . Since photosynthesis is rate limited, the rate of energy intake can be reduced in order to reach the compensation point; lowering the light intensity would slow the rate of photolysis and thus photosynthesis. Similarly, an increase in light intensity

increases the rate of photosynthesis- the CO2 level would be reduced as more inorganic CO2 is fixed, together with producing O2 as waste.
would increase the temperature of the environment- light energy is converted to heat energy which increases temperature.
lead to higher levels of humidity- the heightened temperature increases the rate of evaporation of water from tissues, and thus increases the humidity (water vapor content of the surrounding air)

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.
