The answers to last week's multiple choice questions are as follows:

It is fitting and proper at this stage to go into a discussion of a topic in this subject before going into the typical questions and answers of the topic. The topic referred to is "The Law" :

The Law is really very compli cated and it will take volumen to explain clearly what it is and its functions in details. For the purpose of this column, however, we will just go into the general aspects of the Law and the aspects which are relevant to this subject.

The Law, broadly speaking, is a collection of rules made, amended and repealed when necessary by LaW— making or Legislative bodies for the protection of human basic rights and for the prevention of possible expiertation of a person's ignorance of his rights that are due to him in justice. The Law is enforceable by the mechinery of the state (Govern-. ment)

(1)a,The main problem here is to know

where one process stops and the other begins.

Pollination is the transfer of pollsz from the burst anther to a mature stigna. The agent of this transfar-

·rance may be the wind or an insect. But the pollen must come from the same species.

Krtilization is the fusion of a mele gamete (in póllen grain) and a female. gamete (ovule). The sugary saorition of a mature stigns caunes the pollen grain to adhere and encourage it to grow a pollen tubs down, the style towards the ovary: The direction of ita growth is due to the attraction of female elemente in the overуVE Finally, on reaching the micropyle the male gamete which, travelled doim the pollen tube fuess with the ovum (female gazete) thum completing the process of fertilization with the formation of a zygote.

b. The purpose of pollination is to

bringabout fertilization which off÷ acte sexual reproduction, The zygote: becomes an embryo and the ovule growt and becomes a seed within which deve: -lops the embryo, Mithout the prod- uction of more hardy offspring, there would be less chance of the continuation of a healthy species. (except in cases where vegetative reproduction can be carried out, but then, auch a method hae ita disadva

In any developed society,- such as Hong Kong, there must be an acce- ptable system of Law, whereby an division can be drawn between right and: wrong in eo far as human conduct is concerned, "Society must be prot- ected from wrong-doers and dishonest people. For this purpose, the Law declares that doing such and such a thing is wrong, and prescribes the...- type and degree of punishment to be imposed on the people guilty of such an offence, or it shows how a civil s wrong can be redressed or compenset- ed.

When a person is found guilty of, or convicted of a serious offen- ca, the Law declares that be must be punished by being put into prison. The imprisonment serves three import- ant purposes. Firstly, the person imprisoned may through his own conscience reform and become a law- abiding citizen again; secondly, his being sent to prison may serve as a deterrent to others, which is to say, stopping other people from Following his suit to commit an off-

ence of Law; and thirdly, if the prisoner does not show any sign of reformation, at least the community can be safe while he is, being locked up in prison.

So long there is a community of people there is need for a system of Law, particularly in a business community, where frață, dishonesty, forgery and embezzlement are not uncommon. Unless everyone in the community is so honest that his word is his bond, and unless be can steadfastly resist any form of tem- ptation such as oribery and corrupt- ion, we cannot go about our daily tasks without the Law. The Law is. therefore, indispensable to everyone in a civilized community.

The Law in Hong Kong as in other commonwealth countries, falls into 2 districtkinda - common law and stat- ute law

Common Law is based on the cus- toms, habits and folkways of England Down through the ages, the English Judges have been known to decide cas- as in accordance with the customs of the common people. Once a judge has handed down his decision, it becomes what is known as a precedent and is binding on future case tried in his court and the lower courts. The decision then becomes part of the common law system. A judge'a opinions which are often given to justify and strengthen his decisions are another basis of the common law. As custome do not change suddenly or easily, it is obvious that common law remains for the most, part unchanged and has a long and traditional history of its

Own.

The statute law is enacted by law-making bodies of the State, Va need new laws to implement the common law from time to time, In Hong Kong, the Legislative Council is the' law- making body. All laws enacted by the Legislative council are called

ordinances and fall under the cate gory of Statute Law. If there should be a conflict between Common Law and Statute Law, the latter is superior and is the one applicable.

(iv) ovary and/or receptacle swells.

2. a. When the pollen comes from the same flower it is known as self-pollin- ation but if it dame from another flower of the same species, it is known as oross-pollination.

b. The advantages in areas-pollination

(1) The gametes are small and numer

oust the process, therefore is -physiologically scenonical.

(11) The union of two strains of

parental nuclear materials tends to produce more healthy offsprings.

(iii) Valuable qualities may be contr- ibuted by each parent thos producing a more hardy or even new Variety..

(iv), Deterioration of the species less probable in other words diseasen of one parent may be passed onto the next.

(v) Offsprings are more widely

dispersed.
