Answer:
D. The dodo was unable to adapt to environmental changes.
A) a multiple allelic system
B) sex linkage
C) codominance
D) incomplete dominance
E) epistasis
The flower color trait in radishes, as described in your question, is a classic example of incomplete dominance, as the offspring's phenotype (purple flowers) is a blend of the parental traits (red and white flowers).
The flower color trait in radishes, as described in your question, is an example of incomplete dominance. In incomplete dominance, neither allelic version of the trait is completely dominant, resulting in an offspring phenotype that is a blend of the parental traits.
In your presented case, neither the red flower trait nor the white flower trait is entirely dominant, which is why a cross between a red-flowered and a white-flowered radish produces all-purple offspring. This is a classic example of incomplete dominance in biology.

Answer:
The answer is TRUE Edge confirmed
The major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.
Gram-positive bacteria do not contain an outer plasma membrane, whereas Gram-negative bacteria have a lipid-rich outer plasma membrane.
This outer plasma membrane contains lipopolysaccharide (LPS) in addition to phospholipids and proteins.
Moreover, Gram-positive bacteria are also surrounded by thick layers of peptidoglycan.
In conclusion, the major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.

Answer:
Microbiologists use the gram stain technique to identify the gram-positive and gram-negative bacteria on the basis of the composition of their cell wall.
The major difference between the cell wall of gram-positive bacteria and gram-negative bacteria is that in gram-positive bacteria peptidoglycan is the major component which makes gram-positive cell wall whereas in gram-negative bacteria their cell wall has a thick outer layer of Lippo polysaccharide and a thin inner layer of peptidoglycan.
So in gram stain gram-positive cell wall retains the crystal violet because of the thick peptidoglycan layer and appears violet and gram-negative appears pink as it lacks the outer thick peptidoglycan layer.
Answer:
The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later
