Answer:
1. codominance Both members of an allelic pair contribute to phenotype producing a mixture of phenotypic traits
2 . Rh factor: An inherited protein found on the surface of the red blood cell membrane
3 . hemophilia: A hereditary condition for bleeding due to the inability to clot properly
4 . holandric gene: A gene located on the Y chromosome in XY species
Explanation:
Codominance occur when a pure breeding White flower crosses with a pure breeding Red flower and gives PINK offspring
Rhesus Factor is an antigen that appears on the surface of red blood cells. it is an important factor to consider during blood transfusion.
Hemophilia is a sex-linked condition where the sufferer is unable to have a blood clot.
Holandric gene can ONLY be passed from males (carriers of XY chromosomes) to their sons
Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
Explanation:
in dim light the iris contract ,the the pupils widens to allow more light to enter the eye,in bright light the iris relaxes and size of pupil becomes smaller to reduce amount of light entering the eye. NOTE: the muscle do not expand they either contract and relaxes
