Answer:

carbon dioxide

Explanation:

Carbon is present in both the hydrosphere and the atmosphere as carbon dioxide (CO2). This compound is derived from the combustion of plant remains and the respiration of plants and animals. CO2 is absorbed by chlorophyllated plants and chemosynthesizing bacteria and is used to form carbonated organic compounds (cellulose and starch).

Part of this gas returns directly to the atmosphere by breathing in the plant. The plants are ingested by the animals. From the combustion of these foods in the animals' organism, CO2 returns to the atmosphere, or when these animals die, it will be part of the organic debris that, due to the death of chlorophyllated vegetables and bacteria, will form vegetable debris, which upon combustion will return the CO2 to the atmosphere.

Answer: In the case of the celery in salt water, water would leave the cells and the stalk will become wilted.

In the case of the beaker with plain water, the water will move into the cells in the stalk. You would see this better if the stalk was already wilted.

1. Simple columnar and pseudostratified columnar epithelium both are considered simple epithelium that consist of column-shaped

Y_Kistochka [10]

Answer:

Both options are true.

Explanation:

The cylindrical epithelium is a simple epithelium, which is characterized by having a cell layer, where all the cells are supported on the basement membrane, and its nucleus has reverse polarization in relation to the rest of the cells of our body, that is, they are found in a not very common position.

Simple cylindrical epithelia are found in areas of absorption or assimilation and exchange of gases or nutrients, since this shape is what allows them optimal diffusion through the epithelium, an example of the tissues in which this cellular architecture is found. They are the intestinal tract and the respiratory tract.

In the case of pseudostratified epithelium, it is very similar in function to the cylindrical one, with the difference that it gives a multilayered appearance, that is, its cells are stacked one from the other, giving the appearance of more than one epithelial layer as the stratified epithelium of our epithelial organ, but nevertheless it is not like that, there are many cells of irregular shape with a support in the basal one, that is why it is a single layer.

This last epithelium is also found in the airways in large numbers.

olganol [36]

Answer:

The missing word is Repair.

Explanation:

It is known in medical parlance that if handled correctly, DNA repair can lead to correction of the diseased gene.

The known/major methods for gene repair are:

repair of base excision
repair of nucleotide by excision and
mismatch repair.

Nutritionists some nutritions also claim that certain foods such as strawberries, celery, broccoli, and even lemon can help repair DNA.

Cheers!
