25 % is the probability that one of the offspring from that cross will have only the b factor. So, the correct option is (D).

A Punnett square is defined as a specialized tool derived from the laws of probability that is used to predict the likely offspring from a cross or mating between two parents.

An example of a Punnett square which is shown in the attached image shows the results of a cross between two purple flowers, each with a dominant factor and a recessive factor.

Only one in four plants or 25% of the plants had white flowers (bb) containing only b while The other 75% have purple flowers (Bb, Bb), because the purple factor (B) is the dominant factor. This shows that purple color is the dominant trait in the plant.

Thus, 25 % is the probability that one of the offspring from that cross will have only the b factor. So, the correct option is (D).

Solutes move along a concentration gradient in a solution or across a semipermeable membrane via simple diffusion.

Simple diffusion is accomplished through the formation of hydrogen bonds between water molecules and solutes. Water molecules surround individual solute molecules, maximizing hydrogen bonding. However, hydrogen bonds are extremely transient, and the solution is constantly stirred as a result. This aids in the even distribution of the solute throughout the solution. This simple diffusion can occur across cell membranes, between the individual phospholipids that comprise the membrane, if the molecules are small enough. Water can move along a concentration gradient through a cell membrane in this way, which is known as osmosis.

Depending on which specific class of genes is inhibited in each whorl, the flower structure would be altered by the absence of petals (b), the absence of stamens (c), or the absence of sepals (a), while the other floral organs would still develop according to their genetic program.

The ABC model of flower development is a widely accepted model that explains the genetic regulation of floral organ identity in flowering plants. According to this model, different combinations of three classes of genes, namely class A, B, and C, determine the development of four floral whorls: sepals in the first whorl, petals in the second whorl, stamens in the third whorl, and carpels in the fourth whorl.

Inhibition of class B genes in the second whorl would disrupt the development of petals, resulting in a flower without petals. This would lead to a flower structure with only sepals, stamens, and carpels.

Inhibition of class C genes in the third whorl would affect stamen development, resulting in a flower without stamens. The flower would still have sepals, petals, and carpels.

Inhibition of class A genes in the first whorl would affect sepal development, leading to a flower without sepals. However, the remaining floral organs, including petals, stamens, and carpels, would still be present.

Answer:

The polarity of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.

The cohesion of water molecules to each other helps transport water from the roots to the leaves on plants.

When water warms or cools, hydrogen bonds either break or form.

Thus, water absorbs or releases a great deal of heat, helping to moderate temperatures.

Water is a versatile solvent.

Blood and other biological fluids are aqueous solutions with a diversity of dissolved solutes.

Explanation:

The sentences presented in the question above had their various spaces complemented by the words that best fit the sentence and that were capable of forming true invormations on water.

Water is a very versatile solvent as it is capable of dissolving and mixing with various substances both liquid and solid. Furthermore, water has a great capacity to absorb or release heat, which is very useful for the entire planet, as this allows water to be very efficient in regulating temperature.

Water is formed by H2O molecules, which hold these molecules together are the hydrogen bridges formed between them. Hydrogen bridges are broken through heat, which allows the water to evaporate, but at low temperatures these bridges are strengthened and new bridges can be created, which allows the water to become solid.

The properties of water are extremely important for life on the planet and for most biological processes we know about. Among these properties we can mention polarity and cohesion as one of the most important. Polarity allows water to be a polar substance, while cohesion allows water to create an attractive relationship between molecules.
