Shimasparkle: 1)Arthropoda,2)antibiotics are drugs used 2 cure bacterial infections whyl vaccines re drugs injected in2 d bloodstream to create antibodies that prevent bacterial infections,3)diaphram,5)deamination is the break down of fat by the liver,6)skin,(tear gland.

You tried dear...but let me correct u in No 5: since, the body doesn't store excess protein it is deaminated in the liver. So, it's the breaking down of excess protein by the liver into urea, uric acid etc.
In No8: I think it should be the SEBACIOUS gland!

Cool......

Lateef9961: i dnt lyk arguing sha.

It is neiher argument anyway. I want you to know the FACT.

Lateef9961: yea,ur correct,wrought iron is the ansa,but u stil missed the other two.
Let me start by defining the osmoregulatn.
Osmoregulation is the regulation of amount or level of salt and wa ter in the body. In lower organism like amoeba,their osmoregulator is the contractile vacule,while in mammals,the osmoregulator is the kidney.
Vasopresin or anti durectin hormone is the hormone produced by the pituitary gland.
Vasopresin is used for the absorption of water in the kidney,for more explanation u can go and read the function of kidney.the deficiency of ANTI DURÈCTIN HORMONE is called DEURESIS, deuresis is a condition when excess urine is produce by the kidney. It is treatd by using dueretics drugs 4.gonadial artery ar the blood vessel that supply blood to the sex cell or gonad.
Other types of arteries are CAROTID ARTERY (Head arteries),PULMUNARY ARTERY(lung artery),HEPATIC ARTERY(liver artery),MESENTARY ARTERY(intestinal artery)etc.
So GONADOTROPHIN is a hormone produced by the pituitary gland,it stimulate the production the of sex hormone or either sperm or ova.
Once agaim am sory 4 dat number 7,it is WROUGHT IRON.

When you search and think very well, you will know that I'm correct just the way you agreed with me in number 7.

Lateef9961:
1.displacement is the distance covered in a specifìc directn.
2.scalar quantities ar quantities that has magnitude by no direction.
Examples are temperature,energy,speed etc.
3.vector quantities are quantities that has both magnitude and direction.
Example velocity,weight,magnetic field.
4.acceleration is the rate of change of velocity with time.
A=v-u/t
5. Machine is a device by the means of force applied at one(effort) end use to overcome another force at the other end (load).
6.degree celcius.
7.diaphram
8.gamma ray
9.red,blue and grèen
10.is a light that has been seperatd into its component.
8.

Is No7 diaphram or LENS?

Lateef9961: dnt be angry,he is jst playing wif u

exactly ooo! Abeg I'm jst playing my dear. Am so sorry once again! I like playing jokes. I'm so so sorry pls forgive me oooo

Lateef9961: u got 3/7.
Correction.
1.egestion is the removal of solid undigested waste from the body.
2.vasopresin is a hormone secreted by the pituitary gland.
It is used for the absorption of water in the kidney. Its deficiency is known as deuresis.
4.Gonadial artery
5.cerebrum is divided into two hemisphere.
So the MEDIAN FISSURE is the lining that divided the two hemisphere.
7.pig iron



U EVEN GOT 2/7

hehehehe you must be kidding. VASOPRESIN is another name for ADH. And it's function is OSMO-REGULATION. Gonadial artery is the (Gonadotrophins)! Hmmm! Check your question in No5: You even failed it. Consult your textbooks and confirm it. Reject any textbook that told you that PIG IRON is the purest is a FAKE textbook. CHEMISTRY and BIOLOGY students let's start our research and bring out your references.


My dear friend LATEEF, go and check very well. I will bring out references in due time.

Shimasparkle: wow,dat hurts

sorry dear.........am so sorry!!........which course are you applying for?

Shimasparkle: Wow wow wow,we've all learnt a lot 4rm bio/chem,kudos to guys lyk Ikem and Lateef and the rests,lets take a short switch to physics,,,right here....try it,they're cheap.1=what is displacement,2=what is a scalar quantity,gv 3 examples,3=what is a vector quantity,gv 3 examples,4=what is acceleration,5=what is a machine,6=what is the unit of linear expansivity,7=what part of the camera corresponds to the iris of the human eye,8=which radioactive ray has the greatest penetrating power,9=name the 3 primary colours,10=what is a pure spectrum.

you're questions are cheap indeed!! Please let another help me in answering this. That's SS1 work and some SS3.

Lateef9961: 1.what is EGESTION?
2.what is the usefulnes of vasopresin in the body?
3.what is responsible for the toughness and flexibility of the skin?
4.what is the name of the blood vessel that supply blood to gonads?
5.what is the function of MEDIAN FISSURE in the brain?
6.how meni cranial and spinal nerves ar in a somatic nervous system?
7.out of the three types of iron,wich of them is the most pure?

1) Egestion is the removal of from the body undigested waste food materials.
2) Osmo-regulation
3) Keratin
4)Gonadotrophins
5)Median fissure contains double fold of PIA MATER, its floor is formed by a transverse band of WHITE SUBSTANCE, the anterior white commissure, which is perforated by blood vessels on their way to or from the central part of the medulla spinlis.
6) Cranial = 12 pairs in human and 31 left-right pairs of spinal nerves
7)Wrought iron

But wait ooo! The CO2 is absorbed by the H2SO4 thus the release of CO2 becomes impossible. The equation for the reaction: H2SO4 + CO2 --------> H2CO3 + SO3.
However your explanation more accurate. When CaCO3 reacts with acid e.g HCl, CO2 is liberated:
CaCO3 + 2Hcl -------> Cacl2 + H2O + CO2.
Thermal dissociation of the marble liberates the gas as follows; etc but H2SO4 doesn't give the reaction!
CaCO3 ------------->CaO + CO2
The thing went off my memory!
Thanks bro!!

Lateef9961: èeyah i dnt even dat v commitd a lot of blunder oo,bcus i typed the qstn wen i was working.bt stil u got it sha. U got dat numba 1.
U didnt get dat numba 2 at al.
I wil gve u halve in dat numba 3.


Correction.
2.generally,Co2 is producd in the lab by the reactn of mable CaCo3 with all acid xcept H2So4 bcus H2SO4 wil coat a layer on the mable chip and form Ca(So4)2.
CaCo3 + H2so4---->Ca(so4)2.
3.the blood platelet wil secrete thrombokinase or thromboplastin.
-Thrombokinase wil convert prothrombin into thrombin.
-thrombin in the presence of calcium ion wil convert fibronogen into fibrin and fibrin wil form a mesh on the surface of the wound.

I failed NO2: but in NO3: we are saying the same thing. Review my answer once again!

Lateef9961: 1.Apart from silical gel,what oda compound has the ability to absorb HN3 gas?
2.why is it that H2SO4 is nt use in the productn of Co2?
3.state the mechanism of blood clothing

In NO1: I think there is an error there. Silica gel is used to dry all gases. If any compound has the ability of absorbing certain gas, it isn't a good drying agent to the compound. And two, the gas which you wrote HN3 I think it should be NH3 (ammonia) gas. If it's NH3 gas, apart from silica gel which dries all gases, another suitable compound is CaO (quick lime) which is a hygroscopic substance.
2). H2SO4 readily reacts with the CO2 thus:

H2SO4 + CO2 -----------> H2CO3 + SO3

3). The mechanisms for blood clotting aren't only three.
(i) Formation of prothrombinase
(ii) Prothrombin converted into the enzyme THROMBIN
(iii) Fibronogen (soluble) converted to fibrin (insoluble)

To some it may include; I) vascular spasm (ii) platelet plug formation (iii) coagulation
These are the first step as it involves a complex factors including Ca ion, enzymes, platelets and damage tissues activating each.

Jsplash: Hiiiiiii!
Gud a.m 2 ye all!

same to u bro!

Lateef9961: i made a mistake in dat no 3 i want 2 ryt hypertonic solution.
I got dat number 5 nw.
I got dat number 6 too. it is nt Oocyte,it cerebral cortex or grey matter.
Oocyte simply mins immature egg or ovum in the ovary.

Note, OOCYTE is simply mother EGG CELL. Tnx

Shimasparkle: What is the difference between empirical formular and molecular formular.

Molecular formula is the number and the type of atoms that are present in a single mole of a substance.
While empirical formula is also known as the simplest formula. It is the ratio of elements in the compound.
Some examples are (I): Glucose has a molecular formula of C6H12O6. But the empirical formula of CH2O. The combining ratio of Hydrogen to Oxygen is 2:1. (II) Hydrogen peroxoide has a molecular formula of H2O2. But empirical formula of HO etc..

Lateef9961: Gtd mawni pals.aw was ur nyt.

A DORMINANT GENE is the gene that expresses itself at the first filal generation (F1).
Offspring simply means new young ones produce after sexual reproduction. The features that these offspring possess that can show itself is a dorminant trait.

So it is NOT offspring but dorminant gene

Shimasparkle: all correct,thumbs up ikem,i tink my questns re too cheap,,lol,,,mind u,hiv/aids is an std nt a sex-linked trait

Don't mind my silly mistake. More questions from you

Jewel Bukky: As una don ansa am nw nd ma gurus' dey giv necessary corrections, wat else...
Kudos guyz!


@Mike, y u go giv me 8/10 nw...? I'll find time to check out d ques again nd d corrections u gave sha.

Good morning house!!!

U check and ask questions where necessary for explanation.
