Om maniere te ondersoek wat die uitputting van hout as hulpbron sal verminder
[lu 3.3]
1. Stel ‘n alternatiewe materiaal voor waaruit elk van die volgende produkte vervaardig kan word:
Kurkproppe (boombas)
Rayonmateriaal
Houtplanke vir die maak van meubels
Houtsaagsels
Papier
Dwarslêers (spoor)
Houtkissies (vrugte)
Potlode
2. Watter funksies wat deur bome (woude) as ‘n lewensonderhoudende stelsel verrig word, kan deur niks anders verrig word nie? (Sien par. 1)
Aktiwiteit 3:
Om die belangrikste woudstreke op ‘n kaart aan te dui
[lu 1,1]
Raadpleeg ‘n atlas om die belangrikste woudstreke in die RSA aan te dui.
Indringerspesies
Suid-Afrika se natuurlike omgewing is reeds deur meer as 100 spesies vreemde fauna en flora binnegedring. Dit het aanleiding gegee tot wydverspreide ekologiese skade en verliese van etlike miljarde rande ten opsigte van verlore landboupotensiaal en ander grondgebruike. Boonop is die uitroei van indringerspesies ‘n duur en tydrowende proses.
Die indringerplante wat die afgelope dekades die vinnigste versprei het en reeds honderde duisende hektaar ingeneem het, sluit in
hakea , Australiese
Acacias , die Mauritius-doring, paraffienbos, lantana, waterlelie, nasella-graspol, verskeie dennespesies en die litjieskaktus.
Vreemde visspesies soos forelle en babers het ook reeds sommige rivierstelsels se inheemse vis verdring, terwyl eksotiese voëlsoorte soos Europese spreeus en Indiese myna-voëls ‘n oorlas in stedelike en moontlik in landelike gebiede is. Hul presies getalle is egter nie bekend nie. Uitheemse rotte en muise is probleemdiere in menslike nedersettings, terwyl die Argentynse mier Suid-Afrika se fynbos bedreig deurdat hy die saadverspreidende inheemse mier verdring.
Suid-Afrika se kosbare waterbronne word ook swaar getref deur indringerplante. Oewerhabitats is veral kwesbaar vir indringing en die bo- en middellope van talle riviere is byna heeltemal toegegroei deur digte plate silwer en swart wattelbome (
Acacia -spesies).
In fynbosgebiede het digte plate indringerplante die waterbalans van bergopvanggebiede versteur en skep indringers ‘n baie groter brandgevaar as die natuurlike plantegroei.
Al sewe die belangrikste biosfere word deur indringerplante bedreig en fynbos, savanna en woudgebiede word die swaarste getref. Tot dusver is pogings om indringerplante in die subkontinent se formele bewaringsgebiede in bedwang te bring, met wisselende sukses toegespits op indringerbome en -struike. Indringing deur onkruid en grasse word meestal oor die hoof gesien en weinig ekologiese inligting is beskikbaar oor hierdie probleem.
Aktiwiteit 4:
Om navorsing oor indringerspesies te doen en daaroor te skryf
[lu 1.2]
Om indringerspesies uit te roei, is ‘n duur en tydrowende proses.
1. Skryf kort aantekeninge oor een indringerplant en een indringerdier wat in julle omgewing voorkom.
a) Indringerplant
b) Indringerdier
Enkele voorbeelde van indringerplante
Litjieskaktus
Besmetting deur litjieskaktus belemmer boerderybedrywighede en veroorsaak dat die waarde van besmette grond verminder.
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities.
before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these
Jharna
continue..
sometimes due to these physical problems..the diagnosis may be misdiagnosed.
treatment for autism.
well it depends on the severity.
since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision.
play therapy.
speech therapy.
Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game.
string and beads game.
the more you interact with the child the more effective
Jharna
results you'll get..
please consult a therapist to know what suits best on your child.
and last as a parent. I know sometimes it's overwhelming to guide a special kid.
but trust the process and be strong and patient as a parent.
