<span>The moths that are the same color as the trees in their environment thrive over time due to camouflage, and their populations increase.</span>
Photosynthesis consists of light and dark reactions.
Answer:
If the cell has not properly copied its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death.
Explanation:
<span>Features matched with its description
A: stalactites 3: tubes with hollow centers
B: stalagmites 2: tubes without hollow centers</span>
<span>C: speleology 1: cave science</span>
D: speleothems 4: cave features
<span>
</span>Speleology is shortly defined as the<span> scientific study of caves.</span> Speleothems are structures<span> formed in a cave by the deposits of minerals from water dripping from the fractures of the ceiling of the cave. Most common types are the stalactites and stalagmites. </span>
<span>Stalactites began as a ring of crystals which later becomes small tubes with a hollow center.</span><span> Stalagmites, on the other hand, are tubes formed without hollow centers. </span>
Answer:
How Mutations Can Lead to Human Evolution?
Explanation:
A mutation is the random change in the nucleotide sequence or in the DNA organization (genotype) of a living being, [1] that produces a variation in its characteristics and that is not necessarily transmitted to the offspring. It occurs spontaneously and suddenly or due to the action of mutagens. This change will be present in a small proportion of the population (variant) or the organism (mutation). The genetic unit capable of mutating is the gene, the unit of hereditary information that is part of DNA.
In multicellular beings, mutations can only be inherited when they affect reproductive cells. A consequence of mutations can be, for example, a genetic disease. However, although they may seem harmful in the short term, mutations are essential to our long-term existence. Without mutation there would be no change, and without change life could not evolve.
