Ikemsinachi: 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: 4/5,kudos

Shimasparkle: 1.Where can u find the chromosome in the human cell?2.how is the female/male chromosome represented,3.the gene that is expressed in the F1 generation is called?4.give two examples of sex-linked trait,5.what is haemophilia

Lateef9961: 1.which part of the brain controls vasolidation and vasoconstriction?
2.the hormones that controls metamophosis in amphibian is?
3.which part of the male reproductive is the sperm stored until it x ejaculated?
4.vitamin d is also knwn as what?
5.bowing of leg is causd by the lack of...........?

Shimasparkle: 1=Hypothalamus,3=Epididymis,5=lack of vitamin D,but hey,,im late

Ikemsinachi: ok

Ikemsinachi: Sorry for being late bro. I had a busy day. Am jst returning now!

Well, bro tnx for ur contribution. You tried very well. But you shoul know that MEDULLA OBLOGATA controls on the INVOLUNTARY ACTIONS like yawning, sneezing etc.

When the animal is hot, there is excess heat in the body. Blood flow in the dermal capillaries is stimulated, and the heat vessels in the skin dilated-this is called vasodilation.
Similarly, when the animal is cold, the blood vessels I the skin constricts-this is called vasoconstriction.
The skin does this so as to regulate the body temperature of the animal.
Normally, the flow of blood is controlled by the heart.
But on that node, in the brain there is an organ called HYPOTHALAMUS- it lies bellow the thalamus in the brain that is connected to the PITUARY gland. This hypothalamus regulates the body temperature, osmo-regulation and blood pressure.
So it is the hypothalamus and NOT the medulla oblongata.

Jsplash: 1.Medulla Oblongata
2.Thyroxine nt sure
3.Epidydimis
4.Calciferol
5.Vit. D

Shimasparkle: ok we're waiting

Ikemsinachi: Good one here! You made me release that the protozoa {tryposome} lives in d salivary gland of a tse tse fly. It affects mainly farm animals like cow. The effect on them makes the cow suffer from fever-- I've forgotten d name of the fever. It also causes weakness to cow. Where there are too many cows, tse tse flies must be there.

You tried bro! I failed it woefully!!

adebayor1490: Okayyyyyyyyyyyyyyyyyyyyyyyyy

Ikemsinachi: No 5:
Cocci are bacteria that are circular in shape. They may stick 2geda to form chains {stretococci}, they may occur in bunch or cluster {staphyloccoci}, they may also occur in pairs i.e. they stick 2geda in pairs{diplococci}.
The causative agent is a bacterium.


Trypanosomiasis is caused by tse tse fly which causes sleeping sickness. Is not a zoonotic disease


Cancer is the outward growth of abnormal cells. Is not a zoonotic disease


Since a zoonotic disease is cured by a veterinary doctor, it must have been a disease related to farm animals. Two options now left, it's either option C or D



Peace#

Ikemsinachi: wat are the two numbers I failed??
