In sexual reproduction of Rhizopus,resistant spherical spores are formed,called zygospores,which are thick-walled,and it makes them resistant to environmental hardships.The zygospores are the only diploid phase of Rhizopus stolonifer reproduction.They are composed of two suspensor cells which are former gametangia or hyphae.There is a suspensor on either side of a large,rough,dark brown spore.They suspensor cells are present to provide support.The zygospores forms from two special haploid haphae of opposite mating types that touch due to hormonal proximity to each other.The two cytoplasms intermingle,also known as plasmogamy.As this occurs,the nuclei of both parents enter the conjuction,causing the resting spore to develop. zygospore has fully formed,meiosis occurs and haploid spores are formed and dispersed.The zygospore can become dormant for several months at a time. Meiosis still occurs and sporangium similar to the asexually produced sporangium is created when the zygospore finally cracks open.

the leaf of a flowering plant is adapted for photosynthesis because carbon(iv)oxide, water, chlorophyll, sunlight, mineral, suitable temperature and enzymes are present. carbon(iv)oxide is diffused into the intercellular spaces through stomata of the leaves and later diffuses into the mesophyll cells containing chloroplasts. menral salts derived from the soil pass into the roots of the plant by osmoisis and dissolved mineral salts are conducted by xylem from roofs of stem. the light from sunlight is trapped.

the tapeworm is an endoparasite which carries out parasitic feeding on its host. food is absorbed though its entire body surface. the hooks and suckers are used for attachment to the intestine of the host to avoid dislogment. the entire body surface is used also for the absorption of food.

3ai.Sewage is a water-carried waste, in solution or suspension, that is intended to be removed from a community.
3aii. -Increased organic matter (from the sewage) breaking down in the river reduces the amount of dissolved oxygen in the water body as the decomposition process uses up the available dissolved oxygen. -Sewage heightens the levels of nutrients, increasing the bioavailability of nutrients, which can increase productivity of plankton near the sewage outfall
3b. Terracing is a soil conservation practice applied to prevent rainfall runoff on sloping land from accumulating and causing serious erosion. Terraces consist of ridges and channels constructed across-the-slope. Terracing is also practice of creating nearly level areas in a hillside area. The terraces form a series of steps, each at a higher level than the previous. Terraces are protected from erosion by soil other barriers. Terraced farming is more common on small farms and in underdeveloped countries, since mechanized equipment is difficult to deploy in this setting.

I.Hydrophytes 1. the moisture inside the plants leaves its function is to lessen water loss it does this by not letting the water diffuse out so easily. The cutile is like a protective film covering the epidermis of the leaves it works as a protective waxy covering and tends to be thicker on the top of the leaf. Without it the sun would evaporate all the moisture leaving the leave dry shrivelled and worth less. 2. The roots work by absorbing water and minerals to be from the soil and transported by the xylem and phloem (vascular bundle) to be used for photosynthesis and respiration

i.Test cross: The crossing of an organism, with an unkown genotype, to a homozygous recessive organism (tester) . A cross between an individual of unknown genotype or a heterozygote (or a multiple heterozygote) to a homozygous recessive individual. Test cross can be used to decide the genotype of the F1 generation. The test cross can be used to support the idea that the recurrence of the recessive character in the F2 generation is due to the heterozygous condition of the F1 . The test used to prove whether any given pair of traits could be alleles (different characters). ii. Monohybrid cross: Monohybrid cross is a term for a pairing in which two members of a parent generation share a genetic trait that is affected by two alleles, or DNA sequences. These parents are typically both heterozygous and the way in which the trait will be expressed in members of an offspring generation can be expressed through a simple analysis in how the alleles can pair off.FiNANCiAL ACCOUNTiNG

Nothing has yet been determined regarding a successor. The point is, on every account, too important to be left open till the present leader has passed away. A change of leadership, always hazardous, is especially hazardous when the army is in the field and the enemy is on the watch. If the Divine wisdom judged it necessary that Eleazar should be invested with the high priesthood before Aaron died, much more is it necessary that, before Moses lays down the scepter, a successor should be appointed and placed in command.(2b)He had absolute trust in GodHe was a man of age,not given to fear.He possessed diplomatic wisdom to quell riots,as seen in his speech to the people,never to fear because of the massive stature of the CanaanitesHe possessed the ability to learn from his master as shown in his decision to spy Jericho just as Moses spied Canaan (5a)Mathew reports that John the Baptist refused at first to baptize Jesus when He(Jesus) demanded that He be baptized by John.This was because John saw himself as not being fit to baptize Jesus,rather Jesus should carry out baptism on him.John must hav thought it unnecessary to baptize He who was sinless,since his(John's)baptism was one of repentance.However,Jesus persuaded John to go ahead and baptize Him to fulfil all righteousness.As Jesus came out of the water after His baptism,the heavens opened and the spirit of God in the form of a dove came and rested on Jesus and a voice from Heaven said;"This is my beloved son,with whom I am well pleased".(7a) The Conversion According to Luke’s historical record (Acts 9:1ff), Saul, armed with arrest warrants for those of the Christian Way, departed from Jerusalem en route to ancient Damascus, some 140 miles to the north. As he drew near that city, a light brighter than the noonday sun suddenly engulfed him. A voice inquired: “Saul, Saul, why do you continue to persecute me?” The double use of his name suggests a reproof (cf. Matthew 23:37; Luke 10:41; 22:31). Saul responded: “Who are you, Lord?” The title “Lord” was employed at this point as a mere term of respect, for he knew not who had addressed him. The voice was identified as Jesus of Nazareth! The stunned persecutor was instructed to enter Damascus where he would be informed as to what he “must do.” Blinded as a consequence of this miraculous vision in which Christ actually appeared to him (9:17; 1 Corinthians 15:8), Saul was led into the city. For three agonizing days he fasted and prayed. Finally, Ananias, a messenger selected by God, arrived. He restored Saul’s sight and commanded him to “arise, and be baptized, and wash away your sins, calling on his name” (Acts 22:16). After certain days passed, the former persecutor began to proclaim among his fellow Jews that Jesus “is the Son of God” (see Acts 9:19-22).(8a) According to James,believers should be the doers of the word and not hearers only.For if they are more hearers, they are like a man who observes his face in a mirror but soon as he goes awayhe forgets what his face looks like.(8a continues)He who has heard the perfect law and preserves in its by his actions,shall be blessed in his doing. For somebody to be truly religious, he must bridle his tongue,else his religion is in vain,he is decieving himself.To buttress his teaching,James spoke about Abraham's justification, not merely for his matching action that the scripture was fulfilled which says that Abraham believed God,and it was reckoned to him as righteousness.
