Lignin

It is a complex organic polymer that form an important structural materials in the support system of vascular plants and can also be found in some algae. This is an important molecule in the structural composition of cell wall, such as in wood and bark. This also allow woods and barks to have strong, rigid which allows them to no break easily. Lignin can also be found inserted in the cell wall of this plants.

All but one of the girl's traits are determined by her chromosomes. that is
dolphi86 [110]

Out of the following given choices;

A) her sex.

B) how tall she is.

C) how long her hair is.

D) the color of her eyes.

The answer is C. The length of hair is not determined by genetics but rather by the time period of the growth phase (anagen phase) of the hair follicle, before shedding in the telogen phase. The longer the anagen phase the longer the hair will be before shedding. The hair on the head has longer anagen phase compared to hair in regions such as the eyebrows.

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false
kolbaska11 [484]

Answer:

True

Explanation:

<em>The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.</em>

<u>Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells. </u>

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms.  During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

What is the function of RBC
avanturin [10]

Answer:

When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.

The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.

There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.

Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water
