Low profile, monk. Wasn't well known. Scientific community's attention was diverted somewhere else, Theory of Evolution. His article wasn't published in more commonly read journals. Only a few people read his article.
can't be bothered constructing proper sentences lol sorry

+his experimental and mathematical calculations were beyond the understanding of most other scientists. ie progressive

What's so hard about fractions

150% of them lie though.

BWAHAHAHAAHAAH
omg sorry idk why i found that so funny HAHA

Describe the changing composition of blood as it moves though, kidney, brain, lungs, intestines

 

[ocatal]

Kidney - Decrease in nitrogenous wastes.
Lungs - Increase in oxygen and decrease in CO2.
Intestines - Increase in digestive end products.

discuss the role of quarantine in preventing the spread of disease and plants and animals into Austracross regions of Australia

Quarantine prevents the spread of pathogens, organisms which are a potential threat to Australian plants, animals and people. Due to the effective measures taken by the AQIS the spread of such organisms has been substantially reduced, an example of this is the Mad Cow's Disease which affected a great proportion of UK and the countries supplied by them however Australia put a strict ban on the transportation of livestock from UK which resulted in Australia not getting affected by the Mad Cow's Disease. Also, there has been strict measures to control the spread of fruit flies within Australia which has resulted in certain cities being free of fruit flies.

fuck

this is A class crazy bro

kidney-> Blood loses urea, and other toxic stuff
brain-> Blood loses oxygen
lungs-> Blood loses CO2 and gains O2
intestines-> Blood gains glucose and loses O2?
Where does glucose get lost....In the brain?

identify the form(s) in which each of the following is carried in mammalian blood: carbon dioxide oxygen water salts lipids nitrogenous waste other products of digestion

fcking most stupid dot point in the world.

fcking most stupid dot point in the world.

Carbon dioxide: 70% as bicarbonate ions, 23% as carbaminohaemoglobin and 7% dissolved in plasma.
Oxygen: 98.5% as oxyhaemoglobin and 1.5% dissolved in plasma.
Water: Main solvent that forms plasma.
Salts: Dissolved in plasma as ions (i.e. electrolytes).
Lipids: As chylomicrons dissolved in plasma.
Nitrogenous wastes and products of digestion: Carried in plasma.

Explain the relationship between replication of DNA and evolution.

 

[jacksonhughes95]

DNA replication is the process in which two identical strands of DNA are formed. It is significant as it allows large amounts of genetic information to be passed on through generations. New variations are possible if the code changes. If this change is favourable it will enable survival and continuity of the species, in turn allowing the species to evolve suitable to it's particular environment.

Most offspring resemble their parents in a number of characteristics, but there are often some characteristics in the offspring that are unexpected.

Explain, using examples, how genetics and the environment can effect the phenotype of individuals.

Explain the relationship between replication of DNA and evolution.

When DNA replicates in meiosis there is a production of a new set of gametes which have different characteristics. DNA mutation can also occur which too produces a new set of characteristics (for both meiosis and mitosis). If these new characteristics are more beneficial to the organism in terms of surviving and reproducing then that characteristic will have more chances of proliferating by natural selection, thus increasing the occurrence of this characteristic, which is evolution.

During replication, genes can undergo mutation which can result in a change in phenotype. If the gene is a favoured characteristic then it will pass onto the offspring and the characteristic will become more prevalent by natural selection. An example of this is the pepper moth evolution during the industrial revolution.
The environment can also affect the phenotype of an organism. For example, if a bean plant(bullshitting the name lel) is grown in a light-deprived room while it's phenotype is to be short, it will grow tall and thin towards light. Mutations can also occur by the environment, for example if a fair skinned person is exposed to enough UVR then the person's pigments will undergo mutation resulting in the darkening of skin colour.

do tell what i've missed out on
