Reproduction

Asexual reproduction is a type of reproduction by which offspring occurs from a single organism, and inherit the genes of that parent only, it does not involve the fusion of gametes, and almost never changes the number of chromosomes.

Asexual reproduction requires only one parent. Since there is only one parent, there is no exchanging of genetic information, and the offspring are clones of the parent. Asexual reproduction in plants can occur in a variety of forms, including budding, vegetative propagation, and fragmentation.

Different types of asexual reproduction in animals and plants are

• Stems. In some species, stems arch over and take root at their tips, forming new plants. 
• Leaves. This photo shows the leaves of the common ornamental plant Bryophyllum.
• Roots. 
• Plant Propagation. 
• Apomixis. 
• Budding. 
• Fragmentation. 

1. Rapid Populating
Asexual reproduction gives the ability to produce large quantities of of offspring. This helps to fill up niche’s quickly and prevent intruders and competition from invading.

2. No Mates Required
Finding a mate can be very difficult for organisms that are in desolate environments, like the deep ocean. Asexual reproduction takes the need to find a mate away, allowing these organisms to multiply.

3. In Case of Emergency
In terrible situations, plants and organisms can keep themselves alive and produce others to help them without the help of a mate, or other reproductive source. Plants are a great example of this. If no pollinator is available to pollinate, then they can clone by asexual reproduction.

4. No True Investment
Asexual reproducers do not have to carry their offspring for a long amount of time and produce more than one at a time. This makes it a quick and inexpensive process for them in the terms of time.

Science

Why do cells reproduce:  Growth - increase in number of cells

                                         Maintenance of existing cells

                                         Repair of damaged cells

What is cellular reproduction:

Enables parent cell to pass on genes & cell components to daughter cells

Process = cell division

Different organisms reproduce by

Cell division in prokaryotes

1. Genetic information = single, circular dna
2. Prokaryotic cell division = Binary fission
3. DNA copying is first
4. Protein ring forms
5. Sep = cross wall forums
6. One genome goes to each daughter cell.
7. End result: 2 genetically identical daughter cells.

DNA: Organized in chromosomes

Accurate passage of genetic info is difficult.

Chromosomes help organize the process

remember:

Genes = code for protein

Genes = Sequences of nucleotides

           = Segments of dna double helix

Chromosome Contains:

Dna double helix

Centromere

Histones:  Proteins packaged with DNA (Chromatin)

DNA Orginsations:

Chromosomes occur in homologous pairs

Each homologue is same length and contains same genes in same order.

Diploid: cells with pairs of chromosomes (2n)

Found in most cells of the body

My E-portfolio - My blog & year 10 digitech google+ community

My E-portfolio is going to be used to visually showcase the work that i will be doing in technology this year. I will be doing in technology this year. My blog will be used to reflect on my learning in technology. The Year 10 DigiTech Google+ Community will be used to collaborate with other students about the work that we complete in Digitech.

We will be developing a game relating to "sustainability" we have been trailing a game to learn new skill in scratch.


These are the skill i learnt

• Learnt how to code
• Learnt how to make back drops
• Learnt how to make sprites

Pak 'n Save Poem

Dear Manager

My teacher goes to Pak ‘n Save everyday.

She ask to pay but they say nay.

It’s OK, they say to her.

Thanks for the donation you kind sir.

I’ll be back tomorrow if you don't mind

Of course, if it's to help mankind.

My teacher, asks for a box

you say sorry no boxes in stock

She comes to school and blonks it down

Mr Hendricks frown is turned upside down

Thank you from all of us from GI school

Manger our love's out to you.

Length of Chains

                   Walt 1) Arrange length in order.

                           2) Find Mean, Median, Mode, Range.

                           3) Explain the differences in length.

        

Pairs	Length of chain in centimetres
Ben & Dion	86
Wesely & Koliata	169
Lorenzo & Liam	170
Ifa & Tane	192
Alyssa & Shanelle	192
Andrea & Lana	200
Ketura & Serena	220
Stephanie & Cherish	286
Petuana & Yazmin	304
Munokoa & Samuel	320
Viliami & Howard	383

                      

                           

                      Mean of this table is 230.

                      Median of this table is 200.

                      Mode of this table is 192.

                      Range of this table is 297.

I Knew Ben and Dion’s chain was the smallest because it was a sad 86 centimetres long and that Viliami and Howard’s was the longest because it was whopping 383 centimetres long. To make Ben and Dion’s chain longer they would of had to cut the strips skinnier. To have made every one chain longer they would have to cut their strips skinnier.

E-asttle score T4 2015.

In this test I got a 4a and last time I had dropped from a 4p to a 3a which was dreadful. I was very proud of myself and I think that my score when up because of my self confidence. Over all  I am above the national standard and I have a pretty good score.

Watched the RWC on Sunday morning.

Watched RWC on Sunday morning.

Watch            Did not

B   G             B   G

10  5             3    7

We got this data by show of hands. It is clear that more boys watched the RWC than the girls. I think it is because the boys are more  interested in the RWC than the girls. In our class we all made a prediction and I had the closest prediction the score was 34 for the All Blacks and 17 to the Australians. I put down 32 for the All Blacks and 17 to the Australians.

All Blacks VS Australia

This Sunday NZ go up against Aussie. It will be a tough fight but I think and hope the All blacks will come out on top. I predict the score will be 32 to the All Blacks and 17 to the Aussies. I think the player of the day will be Beauden Barrett or Ma’a Nonu. Hopefully you give it your all, All Blacks.

Basic Facts T4 2015

For my latest Basic Facts score I got 656. I Improved by 4 because I had 648 and even though that's not a big leap it’s big enough. The reason I only increased by four is because for every answer you get right that's two points and I got more than before so I have improved.

I think I’m at the national limit only just. The next thing I need to learn is my hcf, lcm and prime numbers.

Not allowed

In the weekend I was not allowed to go to my friend Munokoa's house for the night because my parents did not know my friend. I told them Samuel my best friend who they knew might be going for the night. So they said "if Samuel can go than you can." It turned out Samuel's mum said no because she did not know him as well.

Dear Mrs Parkes

Dear Mrs Parkes

Thank you for all the help you have given not only me but my class. Also for the suggestions you gave to my teacher.

You have really helped me with my writing and I think because of that I concentrate more on my sentences and making sure I have good ideas for my stories.I concentrate more on improving my work than I use to.

I really enjoyed the the 4x4 poem, descriptive writing and persuasive writing. The 4x4 poem was different than anything I had done before. The descriptive writing I have done before but you gave me more ideas for that as well. My absolute favourite was definitely the persuasive writing.

Next term I have to focus more on my editing.

Once again thanks for your help and I hope you continue to help us.

Yours sincerely

Robin

E-asttle T3

This is my E-asttle score from this term. I have dropped dramatically since my first test this year. I am very disappointed with my score but I don't know what happened, I tried super hard. I tried to get at least 4a but that didn't happened. According to E-asttle I need to learn to estimate numbers reasonably.

 

Flag change

Everybody In NZ have their own opinion about the changing of the flag and which one they like but, the original flag I grew up with. Seventy percent of NZ want to keep it the same so that means only thirty percent want to change it. In my opinion, why waste twenty five million dollars on something small instead of on something that would make a difference in our communities and the people living here. Yes sure the national flag symbolizes our country but why have a flag that does it for us, tourist don't come to NZ because of the flag they come to see our beautiful scenery and welcoming communities. If we made our communities look better and the people in the communities happier than maybe more tourist will visit and enjoy it more.
