Explanation:
Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.
The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.

Answer:
Toxic Algae Blooms
Explanation:
Floodwater deposits a large amount of sediment. excess nutrients promote the growth of algae is a cause of eutrophication.
Answer:
Carbohydrates, Nucleic acids, Proteins, and Lipids
A carbohydrate is a biological molecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom ratio of 2:1.
Nucleic acids are bio-polymers, or large bio-molecules, essential for all known forms of life.
Proteins are large bio-molecules, or macro-molecules, consisting of one or more long chains of amino acid residues.
In biology, lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others.
Explanation:
<span>Symbols for lipids is C and H.
It also contains Nitrogen and phosphorous. DNA or RNA their symbol is C, H, O, N, P. Protein contains both sulfur and selenium which are C, H, O, N, P. Proteins are subunits of amino-acids.
Proteins can be carriers, signaling structural and also immune responses. They are made of the nucleus.
Lipids are hydrophobic and are naturally found in the body to mean that they don't mix with water reason being they are non-polar. Lipids make up phospholipids bilayer.
DNA is supercoiled, and their backbone which is made up of phosphate and sugars groups.</span>
