i) Saprophytes are plants, fungi, and microorganisms that feed on dead or decaying matter (or, in more current and specific usage, they feed on the fungi that feed on the decaying material).
ii) examples are
----> molds
----> ghost plant or Indian pipe
---->mushrooms
---->gnome plant.

Sexual reproduction:This is a type of reproduction which involves the fussion of male gametes(eg sperm cell) and the female gametes(eg egg cell) to form zygote which later develops to a young offspring

-Mutualism represents a symbiotic relationship where both species involved benefit from the relationship while commensalism represents a symbiotic relationship where only one organism benefits while the other does not benefit from the relationship
-Good examples for mutualism include the relationship between bees and flowers as well as humans and digestive bacteria while Examples for commensalism include hermit crabs using dead gastropods for shelter or millipedes travelling on birds

i)Hooks and suckers allow it to hold on tightly to the wall of the intestine
ii)Its flat body gives it a large surface area to absorb food
iii)It has no need of a mouth or gut as it absorbs already digested food
1ci) See the diagram.

Lightning. 1. A discharge of atmospheric electricity, accompanied by a vivid flash of light, commonly from one cloud to another, sometimes from a cloud to the earth. The sound produced by the electricity in passing rapidly through the atmosphere constitutes thunder.
(6ii)Nitrosomonas A genus of gram-negative, ellipsoidal or rod-shaped bacteria whose major source of energy and reducing power is from the oxidation of ammonia to nitrite. Its species occur in soils, oceans, lakes, rivers, and sewage disposal systems
[4/26, 09:43] DannyYoung Blogger: (6ai)
The enormous energy of lightning breaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxides. These dissolve in rain, forming nitrates, that are carried to the earth.
(6aii)
This organism oxidizes ammonia into nitrite as a metabolic process. Nitrosomonas are useful in bioremediation. They are important in the nitrogen cycle by increasing the availability of nitrogen to plants while limiting carbon dioxide fixation.

Azotobacter helps to synthesizes some biologically active substances, including some phytohormones such as auxins, thereby stimulating plant growth.
[4/26, 09:43] DannyYoung Blogger: 3ci) saprophyte are organisms which feeds and get their energy from dead and decaying organic matter. their feeding activities causes decay.
hence, they help in the recycling of organic materials.

Summary of Differences Between DNA and RNA. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is responsible for storing and transferring genetic information while RNA directly codes for amino acids and as acts as a messenger between DNA and ribosomes to make proteins.
