Answer:
A,B and AB
Explanation:
Firstly homozygous are dominant in RR
Then heterogeneous are recessive in r
IF
RR breeds with rr
RR. Rr
f1 generation=Rr
Then
f1 crossing
Rr. and. Rr
f2 generation= RR,Rr,rr
Some general comments about gas exchange and diffusion will be made, followed by a description of how oxygen is carried in the blood. The binding of oxygen to hemoglobin will be discussed, including the oxygen saturation (or dissociation) curve and factors (allosteric effectors) which cause it to shift. Next, a discussion of the effects of carbon monoxide on oxygen binding will be presented. Finally, a description of artificial oxygen carriers will be presented. Most of these topics are covered in standard textbooks [6,10,54,113] and monographs on oxygen transport [112].
Answer: c) central vein.
Explanation:
The liver is an organ that is present both in humans and in vertebrate animals. It secretes the bile, essential for the digestion of fats, and it also has many other functions, including the synthesis of plasma proteins, storage of vitamins and glycogen and detoxifying function. It is responsible for removing various substances from the blood that may be harmful to the body, including alcohol, making them harmless.
The liver is divided by the sickle cell ligament into two main lobes, right and left. <u>There are two other smaller lobes, the square lobe and the caudate lobe</u>.
The hepatic triads are triangular areas located at the angles of the hepatic lobules, made up of a lax conjunctive stroma. <u>They contain a branch of the hepatic artery</u> (that irrigates the liver<u>),</u> <u>a hepatic portail vein</u> (a thick blood vessel that carries blood from the gastrointestinal tract and spleen to the liver so that nutrients are metabolized<u>)</u> and <u>a bile duct</u> (transports bile into the small intestine). Therefore, it does not contain a central vein.
1 2 and maybe 3 for sure 1 and 2 not 3 though
