A book is sliding along a desktop. Because the book is in motion, you know that the forces acting on the book are ______? What i

s the force acting against the book?

Answer:

Normal force, gravity and Friction.

Explanation:

The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table. If the friction is low between the book and table then the book moves easily on the surface.

Carbon dioxide and oxygen enter and exit a leaf by diffusion. which structure(s) on a leaf allow(s) this process to happen?
Montano1993 [528]
The stomata and their guard cells allows this happen.

Stomata is like a hole or gap on a leaf, most of them are present in a bottom side of the leaf, since waxy cuticle is not present over there. And 2 guard cells make up a stomata.

Guard cells are able to control the size of the stomata, depending on the situation. For example, the guard cells close up during day time because a lot of sunlight may cause more water loss.

In conclusion, guard cells and the stomata are the main structures that allow carbon dioxide and oxygen (water too) diffuse in and out of leaves.

Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, a
sattari [20]

Answer: natural selection

Explanation:Natural selection, gene flow, gene drift and mutation are the mechanisms for EVOLUTION.

The dominant purple allele must have been acquired from previous parent gene, by natural selection

Definitely the available   alleles from previous flower population were white and purple flowers. But, because the parents of purple flowers exhibit VARIATION, in their gene pool,  they showed dominance over  the recessive white colour flowers in the same population.  

◼ from Darwin’s observation and deduction, Organisms who acquired certain characteristics from variation  tend to survive than others, and therefore pass these inheritable characteristics to their offspring.

◼Thus the purple flowers dominated the population for the available resources, among the other flowers colours, (competitions) therefore it leads to a stable population in size after a period of time., while the white colour flowers are recessive

◼Darwin concluded that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).

Based on this, natural selection takes place, and the purple flowers with best variation will have selective advantage (dominance)above white colour flowers(recessive).

Consequently, they have higher survival rates compare to white flowers in the population this is   survival of the fittest by natural selection of purple flowers

The frequency of the white colour flower will reduced because of less manifestation of traits from generation to generation from reduced gene pool due to recessive trait, however the frequency of Purple flower will increase because the number of copies of allele of purple flowers is greater than the total number of all the flowers population( white flowers+purple)
