The correct answer is eukaryotic cells.
Microscopic subunits within the cell represent the organelles found only in complex eukaryotic cell. The communication between those organelles via signal molecules are also a good example of the functioning of eukaryotic cell.
Eukaryotic cell is a cell that contains a nucleus and organelles, and is enclosed by a plasma membrane.
When the organism become bipedal, they walk with 2 legs so there are 2 arms that were unused. Some of them try to use that hand by grabbing stick or stone, leading to tools. They start to think more to develop tools and their brain capacity become increased.
The ability to use stone tools will help in food digestion since it can break the food easier. This reduces the needs for bigger teeth/jaw.
the correct answer is A- Reproductive isolation occurred through behavioral isolation
A process of formation of a new species from an existing species is called speciation. New species may formed due to geographical or reproductive barriers which isolates the members of a population of a species to form a new species.
In the given question, speciation in In the leopard frogs occurred due to a particular or specific call given by males to the females. The courtship call lead to reproductive isolation due to change in behavior. Such type of behavioral change will help in recognizing mates of the same species and this will act as a reproductive barrier among the other related species.
The reason behind this is that <span>Ruby inherited both alleles, which are incompletely dominant. The correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has actually come to your great help.</span>
<span>The sun's heat supplies and is used in many earth processes such as life and temperature, maintaining balance.
1. Photosynthesis and sustain life
2. Climate and temperature
The one component in photosynthesis that can't be recycled but must be constantly available is </span>energy.
Light energy, mostly from sunlight,<span> is the main requirement for photosynthesis to occur. </span>
<span>Photosynthesis is a process wherein light energy is converted into chemical energy. </span>
<span>Chemical energy is generated to support the various activities of a plant or an organism.</span>
