The two algae seen here are classified as green algae. That means they make their own food by photosynthesis. The algae on the left is one-celled, or unicellular. The algae on the right is many-celled, or multicellular. How are these two types of algae different? Question 5 options: Only the the multicellular algae contains a chloroplast. They are different only in how many cells make up each algae. Only the multicellular algae has chlorophyll for photosynthesis. The multicellular algae cell has many more parts than the unicellular algae.

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
