The center is a sugar molecule(ribose), the side with carbon and nitrogen is called the base, and the other side is a phosphate chain.
Answer:
The correct answer is: 25 %
Explanation:
According to Mandel's law of inheritance, the dominant allele masks the expression of the recessive allele if present together. If a couple has 3 children with brown eyes. In a monohybrid cross, the ideal phenotypic ratio of the offsprings is 3: 1 or in other words, the dominant character chances to appear is 75% in phenotype.
So, by the law of dominance of monohybrid cross the chances of the fourth child to develop blue eyes is 25%.
Thus, the correct answer is : 25 %.
Answer:
Mutualism
Commensalism
Parasitism
Explanation:
In mutualism, both organisms benefit.
<em>Ex</em>. Sea anemone and clownfish. Clownfish gives the anemone food, the anemone allows the clownfish to use it as a home.
In commensalism, one organism benefits, while the other is neither harmed nor benefited.
<em>Ex</em>. Sharks or whales and remora fish. The remora rides along the belly of whales or sharks and when it eats, the pieces that float around, the remora eats the excess.
In parasitism, one organism is benefited, while the other is hurt.
<em>Ex. </em>Dogs and fleas. The fleas are constantly biting and feeding off of the dog's skin. The dog gets bitten and itches a lot.
Mutualism and commensalism are similar because at least one organism is benefited.
Parasitism and commensalism are different because instead of one organism not getting hurt, like in commensalism, that happens in parasitism.
Answer:
organelle X
Explanation:
the nucleus controls all activities carried out by the cell
Answer: All living things are comprised of cells are in the case of unicellular organisms a cell. And what determines if something is living is whether are not it can reproduce without the assistance of a host organism. Some organelles all cells contain whether prokaryotic are eukaryotic are cell membranes Genetic material (DNA and forms of RNA) a cytoplasm and ribosomes. Obviously there are many more organelles but these are some shared by all cells whether prokaryotic, eukaryotic or plant a type of eukaryote.
