I get A level biology questions ....
Should I continue?

I don't undastand....is 304 d jamn score or number of student

Mine is My father and mother and myself...
Chikenna...���

Keep it coming.........

Littlefinger:
Neurons? That's a first, but why don't they utilize fats?

u see fats have what we call the glucose sparing effect...This means that whenever enough fat is available for metabolism glucose is left alone for cells that can't do without which is the brain....

the explanation is complicated but let leave it simple

GdexFolami:
Chemistry!!!

Hehehe.....
inside the airbag of a car there is a gas that when it is decomposed cause the bag to inflate when accident happens ....

What is the gas??

define isobars isotherm and tautomerism

Littlefinger:
Jesus is Lord! Just when I was starting to feel like a guru. well, I cannot kill myself, so I will answer the questions I know which are the 1st and last. 1st-Parotid gland last-Glucagon, Insulin, Somatostatin. what are the answers to the others?

Hehehehe....

Types ofpsuedopodia are axopodia. lobopodia. reticulipodia. filopodia..

Example of the cells are the neurons

Oya ask me any question both advanced or olevel.......

whales2020:
nice one here.... well,am a part 3 MBBS student of OAU... feel free to drop any questions or request concerning OAU MEDICINE.....

and to our aspirants, freshmen to be.. I say congratulations in advance,

Dr. whales

Hi sir...

I want to ask which textbook do oau medicine student uses for there 200 level for anatomy physio and biochemistry

u see this is simple physics....

Due to the fast movement of the car coupled with the weight of the driver on the balanced side...the car will tilt a little bit which may allow for continued movement...

Physics student will understand.....

fowosh:
course not curse

it was intentional bro......

Hahahahahah.......lol

Which curse were u given in university of ur choice .....

Is it from medicine to soil science
or it is from accounting to library and information science ....
and if u are lucky it may be from pharmacy to food and nutrition.....lol.....
Let's keep it coming.....

Actually none is preferable in Nigeria.....
But I will advise u go for physiology ........

if u study medicine u will unfastand.....

those textbooks ehn......


pharmacology anatomy physiology and d rest........

Which u must buy by fire by force if u want to pass ......

although PDF file is available most don't like it due to concentration and other factors......

Those textbooks are costly. sha

pls do oau uses only five subjects in olevel like ui for screening or all our olevel subjects for screening??

like ......If u what to know the molecular basis of the causes of sickle cell

it is not right for muslims to pray inside the church.....

it does not follow the sunnah of the prophet.....
I am not against love in religion it is just not right for Muslims to pray in church.....

Shut up and stop making empty threats. He is entitled to his own opinion, and so are you. The Europeans and Americans that practice racism are they not developed?
You just bring up any reason as to why African and Nigeria is underdeveloped.

Because europeans and Americans are developed is not a point to encourage RACISM .............SMH......

But which kind of wahala is this one....
After 9months of strike.....
Those government will blow at last niooooo.....
Toying with the lives of ladokites.......
but wait and tinubu is the chancellor....SMH

It usually pays off to be a brilliant student

A new born baby's head when touched , one feels a part of the head which is soft to to touch and a beating pulse is also felt..

This part of the skull( which is the baby's head ) is called FONTALLES...

It function is to allow for the head of the baby to pass through the pelvic of the mother during delivery..

After few months the soft is hardened up....

The definition for haploid is often written

“ Half number of chromosomes”

Is Wrong!



The correct one is

“ One complete set of chromosomes which has half number of chromosomes than diploid set”



Organisms are composed of cells. The cell, therefore, is the most basic unit of life. However, an organism is not reducible to individual cells. That is to say that a living organism depends on the intricate ways in which its cells differentiate, specialise and interact.



Every aspect of a cell is governed by the expression of its collection of genes. Genes are composed of nucleotides that are organised into a molecule known as DNA. DNA is considered to be the basic unit of information in biological systems.




DNA codes for proteins. This is only a minority of the whole strand, however, and the rest was considered “junk”. The junk (non-coding) sections of DNA also serve important purposes, such as regulation of gene expression. There are many other genetic interactions that are just as important as the coding sections in determining how an organism develops.

Evolution:

DNA replication is imperfect. The presence of mutagens, faulty genetic repair mechanisms and the sheer number of replications means that mutations inevitably occur. Some prokaryotic organisms can also exchange genetic material with each other.



Viruses can also introduce changes to an organism’s DNA. Since the advent of sexual reproduction, DNA is also being altered at each instance of reproduction. All of these things mean that DNA changes over subsequent generations.




This also means that a population will have variation, differences between each individual. Some changes are detrimental to an organism’s survival. Some changes may improve an organism’s survivability. As long as an organism is a reproductive success, its genes will stand a chance of being passed on.




Environmental factors will affect an organism’s ability to reproduce. These are known as selection pressures and will, in effect, filter a (varied) population for those best able to survive those pressures. This is known as natural selection.There is competition within each niche between organisms that fill that niche. In order to survive, other organisms must either fill other niches or populate a different environment.


This process has continued for an unimaginably long period over an even greater number of generations of organism that must fill niches that are always changing.This process is more than capable of producing the massive spectrum of organisms that exist today. Each organism is well-adapted enough to survive and successfully reproduce in its niche. There is no such thing as a “pinnacle of evolution”

Vultures’ digestion may hold the key to preventing biological warfare.

Vulture stomachs can process and sterilize anthrax spores, and when they eat botulism-infected carcasses, the bacteria gets killed.
When vultures eat dead rodents containing hantavirus, the disease ends in their system, and they’re fine.



Normal Vital signs in human adults:

Temperature
Rectal (most accurate) / Aural (the ear) is 99.6 F/ 37.7

Oral is 98.6 F / 37 C


Blood pressure: systolic (100-120 mmHg), diastolic below (80 mm Hg)


Pulse: normal resting pulse can range between 60-100 beats per minute. This number is decreased in athletes.

The immune system is very complex and can fight many diseases on its own.
