Answer:
Explanation:
(A) Heterotrimeric G-proteins are composed of three distinct subunits (α, β, and γ). Receptor activation causes the binding of the G-protein and the α subunit to exchange GDP for GTP, leading (more...) The second class of GTP-binding proteins are monomeric G-proteins (also called small G-proteins).
Monocots<span> have distinct structural features. L<span>eaf veins of the monocots are parallel. Flower parts are in multiples of three per whorl. Stems have no pith region. Other characteristics of monocots are: its embryo is with a single cotyledon and its pollen is with single pore. </span></span>
Answer:
Option B, Co-dominance
Explanation:
This is an example of codominance inheritance pattern.
When two alleles representing two different characteristic traits are expressed equally in the offsprings resulting from a cross, then this genetic inheritance pattern is called as codominance .
For example -
A red flower with genotype "RR" is crossed with a white flower "rr" resulting into pink color offsrping with genotype "Rr"
Here, both the red and white traits of flower color are expressed equally thereby giving pink color to the offspring flower.
The same thing is happening in case of true breeding black and white mice.
Hence, option B is correct
Answer:
Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up.
