c. When bread is ingested in the mouth, batang mixes it with saliva which contains ptyalin converting it into maltose. It enters the muscular chamber the stomach, it is churned and retained for three to four hours. It then passes to the small intestine where it is acted upon by amylopsin to complete breakdown to maltose and alkaline, intestinal juice that break down maltose to glucose. The glucose is absorbed and transported by capillaries to the liver which processes it. Undigested food passes to the large intestine where water is absorbed and makes the wastes to become semi solids called faeces. The faces then pass into the rectum and out of the body via the anus.

– When one touches a hot object, the sensory receptor in the skin receives the stimulus

– An impulse is transmitted from the receptor to the spinal cord, via the dorsal root/sensory neurone

– The intermediate neurone in the spinal cord passes on the impulse to the motor neurone

– The motor neurone then sends the impulses to an effector organ (muscle) via the ventral root

– All the neurones are linked by synapses across which impulses are sent

– The muscle upon receiving the impulse contracts causing the hand to be withdrawn from the hot object

(Pick Any Three)

(i) It provides water for photosynthesis

(ii) To get rid of excess water in the plant

How to Answer NECO Biology Questions

This section the article is for everyone and especially for all those candidates who are desperate to knowing the right thing to do in order to achieve excellent performance in NECO Biology examination.

The following are the special tips on how to answer NECO biology questions:

Once you have settled to take your examination in the examination hall, the next thing that you must do first is to read through the instructions on top of the page before you can proceed with reading the questions.

Most times, some instructions are specific to some questions, maybe one or two questions. Here, you still have to take those instructions very serious.

Before you can proceed to answering NECO biology questions, it is highly recommended that you read carefully to understand any question before you can start to answer the questions.

It is possible to see questions that would be similar to what you have been seeing before, probably in past questions, but they are not the same.

This is the point where it is very necessary that you meticulously go through the question before you answer, to avoid choosing the wrong option for objectives and giving wrong explanations for theory questions.

In every NECO examination, there is/are usually some questions that are specially made compulsory by the Nation Examination Council. These questions are always seen in the paper 2 which is theory aspect of it.

You must ensure that you are able to answer those compulsory questions before you can think of answering any other ones. The compulsory questions do carry special mark.

Just like any other examinations, the complexity of every question in NECO government examination varies. After you have gone through the questions, you would be able to tell which of the questions are simple and the ones that are difficult.

The best approach in such case requires that you answer the questions from the simplest to the most complex ones. This is important because it will help to cushion you against examination tension.

Not only that, it also helps in the management of your time. If you are finding any question difficult to answer, you have to leave it and go to the next. Thereafter, you can re-visit those questions that you have left unanswered.

Though it is advisable that you start answering your question from the simplest, leaving the more difficult ones at the first attempts, it does not imply that you should submit you examination without answering those ones you skipped.

It quite understandable that you may not know all the asked questions, you are still required choose your answers even the ones that you do not really know very well.

Sometime, your guess can fall in place and become the right answer. So always ensure that you attempt all you question before you submit.

After you have attempted the entire given questions, you still have to go through all the answers to check for any errors and possible corrections.

By going through the questions, you would be able to see any skipped question(s), if any and the ones you mistakenly clicked the wrong options.

It is an error to assume that NECO biology examination is hard. Failure to perform excellently in NECO biology examination is a question of whether the candidate knows the right things to do and if he/she is doing it right.

The poor performance that have been seen in some candidates’ results over the years are as a result of poor application of the basic principles for writing NECO biology examination and some other factors that I am going to show you here.

Inadequate Preparation

This is the most important aspect of the reasons for poor performance in NECO biology that should be considered.

It is obtainable in all areas that when there is poor preparation for any examination they will be poor result. As a good student, you are required to prepare for the NECO biology examination to the point that you would be sure of scoring high.

Reading without Past Questions

During the preparation phase of NECO biology examination and any other subjects, it is very pertinent that candidates make use of past question papers with reference to their answers.

Failure to make use past questions and answers is one the reasons why many candidates are left in abeyance immediately they enter the examination halls for the biology examinations.

Due to the ignorance of the nature of the examination, they will not even know to answer and most time it will result to examination tension and probably fever for the students.

Poor Time Management

Time management is another important factor that can lead to poor performance in every examination. You should learn how to manage your time especially when you are in the examination hall.

The practice of time management starts from the period of the candidate’s preparation for the examination. Once you can answer your past questions comfortably with the limited time that will be provided, you will still manage your time very well on the examination date.

Lack of Adherence to Given Instructions

There are some students who are fond of ignoring instructions when come for examination. Jumping into answering of questions without reading the given instructions is very wrong. This contributes in a big way to poor performance in the examination.

If you want to have good performance in NECO Biology, you have to strictly pay close attention to any given instructions.

Submitting Incomplete Answers

When a candidate submits the examination without attempting all the questions, it will automatically affect his/her score. It is important you answer all the questions before your submission.

The final product, urine, collects in the renal pelvis, flows through the ureters to the bladder, and is excreted via the urethra.
