<span>Algae blooms are the consequence of large amounts of fertilizers in the water. Algae use the presence of increased nutrients and enhance their own growth. It is known that they produce an oxygen in the photosynthesis, so it is not a problem while they are still alive. But when these organisms die, their decomposition begins. For the process of decomposition, the oxygen is needed and ultimately it will be depleted from a body of water. This could lead to the death of aquatic animals that depend on oxygen. So, in the population will survive only those who are able deal with the lack of oxygen in the water</span>
Cross pollination is the transfer of pollen of different species to stigma of different species of plants.
Cross pollination results in healthy, viable and diverse plants.
Mendel observed that traits could either be dominant or recessive.
Blended traits or incomplete dominance is the condition in which dominant allele could not produce its trait alone instead blending with recessive allele takes place giving new phenotype to progeny.
Explanation:
In cross pollination pollen transfer takes place from anthers to stigma. In Mendelian genetics the anthers of the plant was removed because it has both male and female parts on same plant so that self pollination does not take place.
The importance of cross pollination is that it creates diversity in the plant species since the traits having different alleles are combined to form the progeny plant. The offspring are healthier and high quality seeds are found.
Mendel observed that traits are either dominant or recessive in general. It was observed that when homozygous parents were crossed, the progeny in F1 generation always had dominant trait. The recessive trait only appeared when F1 generation offspring were self pollinate.
Blended traits or incomplete dominance appear when alleles get blended and exhibit the traits in phenotype. The phenotype appeared will not be matching with either parents.
The example is a white coloured flower is crossed with red colour flower the resultant colour of the flower is pink. It shows that dominant allele red is not completely dominant and gets blended with white colour.
<span>When there is the presence of gills it will be easy to determine if the animal is aquatic or mollusk.
Aquatic means related to water. While Mollusca is termed as the large phylum of invertebrate animals whose members are called mollusks. Most of the mollusks live in water.
The most numerous mollusks are mantle which is important for cavity and is used for excretion and breathing, the presence of radula and their structure of the nervous system.</span>
