Water's polarity can be responsible for many of it's properties including it's attractiveness to other molecules. Water molecules attract one another based on the attraction between the positive end of one water molecule and the negative end of the other. Also the unequal sharing of electrons gives the molecules a slight negative charge near it's oxygen atom and a slight positive charge in it's hydrogen molecule.
Answer:
North Pole
Explanation:
The surface of the Earth is inclined perpendicular to the sunlight (as in the left hand side of figure 2), and so receives the maximum amount of sunlight per square area. The situation is most extreme at the north and south poles. At the north pole, the season is one long,cold night which last for six months.
Answer:
In general, leaf is considered to be organs of a plant. However, leaves collectively could be called as a foliage. Different tissues make up an organ. The leaf comprises of different tissues:
- The epidermis tissue makes the upper and lower surface of the leaves.
- The mesophyll tissue is present in the centre of the leaves and contains chloroplasts.
- Vascular tissues, xylem and phloem, are also present in the plant which allow transportation.
Answer:
The correct answer will be- Non-Mendelian inheritance (incomplete dominance)
Explanation:
Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.
In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.
Cross
RR (red) x rr (white) = Rr (pink)
Thus, incomplete dominance is the correct answer.
