Explanation:
Cell death, also called apoptosis, is an essential part of life. As cells become old or broken, they are cleared away and destroyed. Mitochondria help decide which cells are destroyed.
The mangroves trees help in holding the soil in place, they help in absorbing the energy of waves, and they help in filtering water and better the quality of it.
Mangroves are a kind of estuarine or coastal wetland, featured by the existence of salt amended shrubs and trees, which develops beside the coast in subtropical or tropical latitudes all around the world. Several of the mangroves forests can be determined by their dense tangle of prop roots, which make the trees seem to be standing on stilts above the water.
The mangroves safeguard the shorelines from destructing hurricane, storms, winds, and floods. They help in inhibiting erosion by stabilizing the sediments with their tangled root infrastructure. They sustain the clarity and quality of water, trapping the sediments and filtering pollutants arising from land.
Answer:
C A single genotype produces a range of phenotypes that differ in the degree or magnitude of expression of the particular trait specified by the gene.
Explanation:
Variable expressivity refers to the range of signs and symptoms that can occur in different people with the same genetic condition.
For example, the features of Marfan syndrome vary widely— some people have only mild symptoms (such as being tall and thin with long, slender fingers), while others also experience life-threatening complications involving the heart and blood vessels. Although the features are highly variable, most people with this disorder have a mutation in the same gene (FBN1).
Charles Darwin; he studied the different beak shapes/sizes of Galapagos finches and found that over time, they changed due to their needs for the food found around them (evolution).
