GENERAL BIO DISCUSSION (3 Viewers)

[SASH_06_X]

What r you guys 's example for this dot point: Investigate the response of a named Australian plant to a named pathogen through practical and/or secondary-sourced investigation, for example: fungal pathogens, viral pathogens.
For the fungal pathogen I am doing Wollemi pine but I can't find a lot of information on it, this is all I have for now:

Example: Wollemi pine
Disease: Phytophthora dieback

Causative pathogen: Phytophthora cinnamomi

Symptoms:

• Rot of fine feeder roots
• Root cankers leading to dieback
• Decline in yield
• Collar rot
• Root lesions
• Leaves wilting and discolouration

The root lesions prevent uptake of water and nutrients from the soil which can cause the plant’s leaves to discolour and wilt. The plant attempts to respond to the pathogen by dropping its leaves to conserve energy to fight the fungus.

Is anyone else doing this plant and if you do can you please give some more info on this????

i use eucalyptus calophylla and the pathogen is sm phyto cinnamon
plant response:

• increased lignin production = protect cell wall from pathogenic damage = physical barrier (catalysed by PAL and phenolics and stuff to maintain healthy and thick plant roots)

ur only gonna get like a 3-4 marker on this so u don't need too much detail

I feel like my trial made me overconfident bc i havent started studying for bio again yet...

Should be right if i memorise all my examples but damn youse are making me scared now

this thread being created was the only reason why i properly started doing bio trial papers again

I'll try and do abt 10 before hsc but really its just about memorisation at this point which is kinda annoyin个 because the concepts are actually pretty enjoyable to learn but after that its just all about the examples

We looked at this similar question on the running bio examples thread

wait i wrote a response idk which thread it was, my eg was banksia and its sooo much easier

Cheers, hope your immune system can recover from the exhaustion of bio content overload

Is anything here relevant for mod 5?

Body Systems:

Respiratory System:
Delivers oxygen around the body and removes carbon dioxide

• Uterus enlarging causes ↑ intra-abdominal pressure
• Diaphragmatic breathing (hyperventilation)
• Tidal volume ↑

Cardiovascular System:
System of organs that deliver nutrients and oxygen to all cells in the body.

• ↑ cardiac output because placental nutrients
• ↑ heart rate
• ↑ stroke volume
• Decreased systemic vascular resistance
• Decreased blood pressure
• ↑ clotting factors

Musculoskeletal System:
Provides a framework for muscles and other tissue, and assists with mobility.

• ↑ BMI
• Stretch marks
• Lower back pain and cramps
• Sciatica (compression of nerves around thighs)

Endocrinological System:
Glands that secrete hormones (chemical messengers)

• ↑ pituitary gland hormone secretion
• Pregnancy hormones
• Β-HCG
• Oestrogen
• Progesterone
• ↑ thyroid hormones

Dermatological System:
Acts as a barrier, as well as body temperature regulator, cell fluid maintenance and Vitamin D synthesis

• ↑ skin pigmentation
• Stretch marks on belly

Gynaecological System

• Due to ↑ oestrogen and progesterone, and growing foetus
• Breast enlargement
• Areola pigmentation
• Vaginal proliferation (↑ lactic acid, decreased pH levels) to protect vagina
• Cervical gland hypertrophy (mucus plug)
• Breast
• Oestrogen causes ↑ adipose tissue, ↑ lactiferous duct
• Progesterone causes breast lobule enlargement

Urological Changes

• ↑ renal blood flow (40%)
• ↑ urinary frequency
• ↑ kidney size

Gastrointestinal Changes

• Oesophageal relaxation
• Intra-abdominal pressure rise
• Reduced level mutility

A is umbilical cord
B is amniotic fluid

excuse me wtf is all this

just know pregnancy hormones

If I was in high school as the person I am today, I would be number 1 in nationals.
Sorry Hiva, but you'd have no chance against a 100%er like me.

 

[[Blank]]

I love being the best, so I wonder what sort of competition I could partake in where I could have fun with friends of mine like @Hivaclibtibcharkwa

 

[[Blank]]

I could do bio, but I would need a reason, for I have limited time.
Hmmm... I actually don't know how competition works between students of different disciplines within uni.
@Hivaclibtibcharkwa, could you help inform me on whether or not my efforts in computer science or engineering can be compared to your biology and teaching studies on a national level?
(I don't want to have a school-district-only competition, because I could just choose to pick any school to study at with that logic.)

 

[[Blank]]

We can 1v1 anytime. I’m always looking for someone that can challenge me.

remember our duels on the bio marathon thread? It’s still there.

Yeah, but the conditions for a 1v1 has to shake the world to some extent.
Like imagine the fight of babalonia with Gilgamesh or the two god Hivas.

Im offering this potential as a genuine possibility, but we have to come up with a competition that includes a MASS of plebeian (in comparison to the two of us) competitions.

guys whats a disadvantage for CRISPR-CAS9 despite the fact that its unethical with the creation of 'designer babies'

guys whats a disadvantage for CRISPR-CAS9 despite the fact that its unethical with the creation of 'designer babies'

talk about how introducing the possibility for germline gene editing raises implications for biodiversity bc you don't know how it could spread and relate it to all of the issues of that so basically (horizontal gene transfer i dont remember sorry, genetic diversity and variation) all that stuff i think. sorry i can't fully remember or even understand what im saying rn its been a while

 

[its_ace21]

horizontal gene transfer

we didnt learn that whats that

 

[synthesisFR]

we didnt learn that whats that

i have no clue sorry its one of those things that i can recall but dont know tf it is

 

[its_ace21]

Bacteria can basically swap genes with each other. It’s another way antibiotic resistance spreads so fast View attachment 40111

ok tysm
