The interaction between two polar molecules would involve HYDROGEN BONDS.
Polar molecules are molecules that have both positive and negative charges as a result of the differences in the electronegativity of the atoms that made up the molecule. Polar molecules interact through dipole dipole inter molecular forces and hydrogen bonds.
The answer is cross-pollination, by using parents that had different traits.
Gregor Mendel researched pea plants and he <span>established the principles of heredity. To explain his experiments and discoveries, he invented terms dominant and recessive in reference to traits. In his experiments, he used cross pollination which includes the crossing of parents with different traits. For example, he crossed a plant with green peas and a plant with yellow peas (two different traits) and studied how these traits are inherited to the next generation.</span>
Answer:
A histone modification mechanism proliferate through a process that includes post translational modification procedure. The methylation, acetylation as well as ubiquitylation are one of the main modifiers that help in activation of silent genes and ultimately these covalently bonded histone modifiers help in regulating chromatin. The PTM has a main role in altering histone structure by these modifier's recruitment....
Answer:The correlated trait exercise shows that when two characters are correlated, the optimal values and selection strengths rise and fall together.
Explanation: Correlation refers to statistical (linear) relationship between two random variables. When traits are correlated, change in one is associated with change in the other.
Correlation coefficient (c.c.) measures strength of association between two variables in the same individual or experiment. It can range from -1 to +1. C.c. can be positive, negative or weak.
1. A positive c.c. means that an increase in one variable is associated with an increase in the other variable.
2. A negative c.c. means that an increase in one variable is associated with a decrease in the other.
3. A c.c. near zero indicates a weak relationship between the variables.
Correlation can be represented by scatter plot as shown in the attached image.
Answer:
Whorl-1- petals
Whorl-2- petals (mutant)
Whorl-3- carpels (mutant)
Whorl-4- carpels
Explanation:
ABC model of flower explains the role of various genes in the formation of a flower from the shoot. Each gene forms a particular structure of a flower in the following manner:
1. A gene -sepals. (Whorl-1)
2. A + B- Petals (Whorl-2)
3. B+ C - stamens (Whorl-3)
4. C- carpels. (Whorl-4)
If a flower lacks the B gene, the effect will be observed in the phenotype in which B gene is involved that is in the formation of petals and stamens or whorl 2 and whorl 3.
The flower will produce
whorl-1- petals
Whorl-2- petals (mutant)
Whorl-3- carpels (mutant)
Whorl-4- carpels
