For all Biology elites (including undergraduate students of BIOLOGY). Let's meet,share ideas and solve questions here.

what is biology

Feel free to throw your questions.
@ Capableben,Biology is a natural science that deals with the study of life and living organisms.

Morning Biologists....have a gr8 day ahead.

How many hormones are produced at the anterior lobe of the pituitary gland? Name them together with their functions.

Ikemsinachi: How many hormones are produced at the anterior lobe of the pituitary gland? Name them together with their functions.

1.somatotropin:it is responsible 4 growth in mammals.
2.vasopresin or ADH:it x responsible for the reabsorption of water in the kidney.
3.oxytocin:1. It controls the flow of milk in the mammary gland.
2.it controls the opening and closening of uterine wall during birth.
4.prolactin:it enhance the production of milk in the mammary gland.
5.tropic hormone:it controls oda hormone in the body.

Under-secretion of Prolactin could lead to a condition called?

Zikdik:
Under-secretion of Prolactin could lead to a condition called?

insufficient breast milk

What is Histology?

Leebliss13: insufficient breast milk

The condition is hypoprolactinimea....tnx 4 trying though.

Histology is the study of the microscopic structure of tissues

You guys are doing great so far. An association that is neither beneficial nor detrimental to either population is .......... ? Give an example if you can.

1.The culticle that protects the outer part of the snail is?
2.which part of the skeletal system is the clavical found?
3.what is the function of the pinnae?
4.the thickest part of the mammalian brain is the?
5.the cells of the eye that detect bright light is?
6.blood is produced in the bone marrow in adult,bt in progeny,wat produces the blood?

ans is commensalism.
1.ramora and shark.
2.man and bacteria in the intestine.

Lateef9961: ans is commensalism.
1.ramora and shark.
2.man and bacteria in the intestine.

Err no...Commensalism is beneficial to ONE population.

1) Chitin.
2) Shoulder blade (or clavicle) is found in the appendicular skeleton.
3) The pinna or outer ear collects and directs sounds to the ear canal or auditory meatus.
4) Cerebral Cortex(not too sure about this)
5) Cone cells of the retina
6) The divisions of the haematopoetic stem cells in the foetus (if that is what you mean by progeny,because projeny naturally means offspring).

Zikdik:

ur kiding me ryt?
How commensalism beneficial to a populatn?

correction
1. Mantle
4.cerebellum
6.liver.

Define commensalism and explain it using of your afore-mentioned examples.

Lateef9961:
correction
1. Mantle
4.cerebellum
6.liver.

1. Ok. I mis-interpreted that question.
4. Thanks,that is a new one for me.
6. The haematopoetic stem cell starts its division in the liver.

oh oo zikdik,am sowi,itx symbiosis.
Examples are:
1.lichen (algae and fungi)
2.nitrogen fixing bacteria and root nodules.

1.How meni muscle attach the eye 2 the eye socket?
2.what x the function of lacteal?
3.what x a chyle?

Lateef9961: 1.How meni muscle attach the eye 2 the eye socket?
2.what x the function of lacteal?
3.what x a chyle?

1)Six.
2)absorbs emulsified fats (chylomicrons).
3)chyle is a mikly fluid containing lymph and emulsified fats.

Lateef9961: oh oo zikdik,am sowi,itx symbiosis.
Examples are:
1.lichen (algae and fungi)
2.nitrogen fixing bacteria and root nodules.

No,symbiosis is any lasting relationship between two organism. Mutualism is a relationship beneficial to both parties. Commensalism is beneficial to one party. Parasitism is harmful to one party.
NEUTRALISM is NEITHER beneficial NOR harmful to either party.
E.g : a squirrel and a bird on the same tree. They donot interact directly,but they belong to the same community.

Leebliss13: state duh all or none law..
.

Sorry guys, i have been kind of busy....can't believe the thread was dumped. Una no do well oh. @Leebliss, "If stimulus excceds the threshold potential, the nerve or muscle fiber will respond completely, otherwise impulse isn't felt at all". That is, for impulse to be felt, stimulus has to exceed threshold potential (70eV).
Who was the first biologist to define the term "prokaryotes" ?

Aristotle

DrPaulB: Aristotle

Err..that was the trick in the question. Aristotle was a philosopher, not a biologist.
The answer is Herbert Copeland.
