Answer:
<em>A. If populations can interbreed, they are considered one species.
</em>
Explanation:
The organisms of a species have the ability to interbreed with one another leading to the formation of an offspring. For speciation to occur, the organism have to get diverged and isolated.
In speciation, a hereditary species parts into at least two relative species that are hereditarily not quite the same as each other and can never again interbreed.
In Allopatric speciation, the species gets geographically parted from their parent and evolves accordingly while in sympatric speciation, evolution of species occur when it stays in the same place as their parent.
Many prokaryotes are adapted to live inside the body because the majority of bacteria are mesophilic.
Depending on the optimal temperature of development, there are three types of bacteria:
* Mesophilic bacteria prefer average temperatures between 20 and 40 ° C. The majority of bacteria is mesophilic. This is the case of pathogenic bacteria of man and animals, but also commensal bacteria of natural cavities, cutaneo-mucous membranes and especially saprophytic environmental bacteria involved in the degradation and recycling of dead organic matter. (necromass).
* The psychrophilic bacteria have an optimal temperature of development close to 0 ° C.
* Thermophilic bacteria can live at high temperatures (45 ° C in hot springs).
A. Fruits provide nourishment for seedlings.
Answer:DNA is the hereditary molecule that determines hair color in humans, However, the DNA molecule itself is colorless
Explanation:
<span>The yeast will produce the most cellular respiration at an optimum temperature. This temperature will be at a normal room temperature. If the temperature of the environment surrounding the yeast is too low, the rate will decrease, because the molecules involved in the process of cellular respiration will slow down resulting in lesser rate. In addition, if the temperature of the environment surrounding the yeast is too great, the rate will also decrease, because the enzymes involved in cellular respiration will denature causing the rate to decrease. Therefore, the yeast will have the greatest rate of cellular respiration at room temperature. </span>
