(i)Muscular contractions
(ii)Villi and microvilli

(2b)
Plants have both chloroplasts and mitochondria and they are convert to starch immediately for storage. The former makes the sugar and the latter turns it into ATP. In other words is the process by which plants use light energy to convert carbon dioxide and water into sugars.
(2ci)
Euglena: use their chloroplasts to produce nutrients through photosynthesis. It is a dual organism as it can act both as an autotroph (make its own food) and heterotroph (feed on other substances).
(2cii)
Spirogyra: Longata performs photosynthesis to receive its nutrients. This alga contains special cells called stomata that open and close so the organism can take in carbon dioxide and release oxygen during the chemical reaction in photosynthesis

(i)Salinity
(ii)Fresh water
(iii)Tidal Influence

Tabulate
-Under Aquatic Habitat-
(i)they live in water
(ii)they respirate through gills or skin
(iii)they have stream line body
-Under Terrestrial Habitat-
(i)they live on land
(ii)they respirate through lungs
(iii)they have muscle and are more stronger to locomote
(3ai)
(i) Illegal falling of trees
(ii) Bush burning

(3aii)
(i) Establishment of forestry departments;
(ii) Establishment of Environment Protection Agency to improve the natural conservation
(iii) Creation of Parks and Games Reserves
(iv) Conservation education should be carried out through tree planting to campaign against bush burning, tree felling or poaching
(v) Establishment of zoological gardens for preserving endangered species.
(3b)
An endangered species is a species of animal or plant that is seriously at risk of extinction. This extinction is usually as a result of human activity.

(i) It helps to improve crop yield
(ii) It helps in production new varities of crops
(iii) It helps in studying the plant diseases and ways of controlling them.

Tabulate,Mode of feeding, features,
(i)Adult mosquito
-Mode Of feeding-
(i)They feed on algae, plankton, fungi and bacteria and other microorganisms In other microorganisms words Externally, the most obvious feeding structure of the Adult mosquito is the proboscis.
-Feature of mouthpart that adapts organism to mode of feeding-
(i)are very specialized, particularly those of the females, which in most species are adapted to piercing skin and then sucking blood.
(ii)Weevil
-Mode of feeding-
(i)they feed either on a single plant species or on closely related ones. In other words Adult weevils tend to be less-specialized in their feeding habits
-Feature of mouthpart that adapts organism to mode of feeding-
(i)consisting of two opposing mandibles, which are used to remove leaf sections or entire leaves. In other words it demonstrate on them to use phloem sap as their exclusive food source. ... Leaf-feeding beetles (Order Coleoptera) possess “chewingâ€
(iii)Cockroach
-mode of feeding-
(i)they have adopted themselves to all types and sizes of diet. To handle the various types of food all the appendages of cockroach act synchronously.
-Feature of mouthpart that adapts organism to mode of feeding-
(i)The mouth parts are composed of paired appendages like mandibles and maxillae and unpaired structures like labium, hypo-pharynx and labrum
(5b)
(i)Mouth and Buccal Chamber
(ii)Pharynx
(iii)Oesophagus
(iv)Gizzard
(v)Stomach
(5c)
(i) Manure spreading
(ii) Fertilizing
(iii) Pesticides
(iv) Animal dungs
(v) Sewage

The housefly life cycle closely mirrors that of most insects: a basic cycle that begins with an egg, then develops through a larva phase, a pupa phase, and finally, into an adult. During a warm summer -- optimal conditions for a housefly -- the cycle, from fertilized egg to adult, spans a mere seven to 10 days. After a male housefly chases down and fertilizes a female counterpart, she's ready to lay her eggs. Houseflies are solitary creatures.
Results which met the Ordinary standard (grades 1-6) were recorded as Pass. ... Grades D and E indicated a lower standard of attainment, but were still judged sufficient to be recorded on the certificate. Grade E or below was ungraded and not recorded on the certificate.
Postgraduate: University of the West Indies - A score of B, 65% or GPA of 3.0 is considered comparable to a UK 2.1, while a score of B-, 60% or GPA of 2.7 is considered comparable to a UK 2.2. ... A Level or CAPE grades will also be considered alongside degree scores.
Is Wassce equivalent to GCSE? Minimum of three passes at GCE A-level at grade C or above, and five passes at GCSE/IGCSE level at grade C or above, including English and Maths with equivalent qualifications such as African WAECs - 6 passes at grades 1-6, including Maths and English.
You are required to get at least a credit pass (50%) in your core subjects. Under the new WAEC grading system, A1 is Excellent, B2 Very Good, B3 Good, C4, C5 and C6 are interpreted as Credit, D7 and D8 are interpreted as Pass, while F9 is Fail.
Yes! It is possible to combine WAEC and NECO result for admission into any tertiary institutions in Nigeria. Many universities in Nigeria allow for the combination of both WAEC and NECO result.
WAEC internal can be easier because you're have been well prepared for the papers most recently (SS1 to 3). People usually write GCE while they'd abandoned books for months - if not years. This may make it more difficult to pass. There are other reasons WAEC internal could be more convenient as detailed in this post.
C6 (50-54%), C5 (55-59%) and C4 (60-64%) are credit grades. B3 (65-69%) is a Good grade. B2 (70-74%) is a Very Good grade. A1 (75-100%) is an Excellent grade.
According to the timetable, the West African Senior School Certificate Examination (WASSCE) for school candidates, 2020, will commence on 6th April, 2020 and will end on 5th June, 2020.
To register for NECO examination, candidates are to obtain a draft and pay a non-refundable fee of Twelve Thousand Naira Only (N12,000) paid via bank draft or to school management if internal registration. The payment can be done in any NECO office, banks and Nipost offices nationwide.
