Answer:

It is usually of uniform thickness. (Ans. E)

Explanation:

In the plant cell wall primary cell wall is existing between the mid lamella and the secondary cell wall. The structure of the primary cell wall is thin, and flexible in nature and they are made up of pectin, hemicellulose, cellulose.

The primary cell wall is the part of the cell wall that has the capability to enlarges the layers by the mechanism known as an acid growth mechanism, with the help of this mechanism plant cells grow via plant cell wall enlargement at a poor pH level.

Genetic code

Cadons

Explanation:

genetic code is the code that allows an organism read the information in it genes. The information provide instructions for building and operating a living organism.

The genetic code is a combination of sequential nitrogen base A, G, U, C formed in the mRNA chain. These four bases is what make of the letters of the genetic code which combine together to form the cadons

In the past 250 years how many volcanoes have erupted?
lesya [120]

Answer:

Graph showing known historically active volcanoes, number of volcanoes reported to be active each year, and population. The line labeled "Known Historically Active Volcanoes" (right scale) is the cumulative number of volcanoes with an historically recorded eruption by that year. "Volcanoes Active Per Year" since 1400 CE (black line) and 10-year running mean of same data (thick red line) is also based on reported eruptions (those with uncertainty dates greater than 1 year are not included, nor are uncertain eruptions). "Population" (right scale) is the world's estimated human population; data from McEvedy and Jones (1978) and (since 1750) Population Reference Bureau, Washington, D.C. See text for further explanation.

A dramatic increase in both the number of historically active volcanoes and recorded eruptions took place about 1500 CE. These resulted in part from the great Spanish/Portuguese marine explorations – the Age of Discovery – around the end of the 15th century, when explorers opened Latin America and much of the western Pacific to European record-keeping. Perhaps equally important was the development and widespread distribution of the printing press in the late 15th century, markedly increasing the likelihood that new volcanological records would survive. Through the 17th and into the early 18th century the recognition of additional active volcanoes generally corresponded with steadily increasing eruption reports. By the 18th century global trade was flourishing, the Industrial Revolution was under way, and the heightened reporting of eruptions noticeably accelerated the discovery of new volcanoes. The list has continued to grow, with several important volcanic regions such as New Zealand, Alaska, and Hawaii being unrepresented until the last 250 years.

iragen [17]

Suppose bad weather and pollution dramatically reduce the supply of crawfish in Louisiana next year. This would most likely lead to an increase in the marginal utility of crawfish consumption.

Marginal utility of a commodity or service is the change in total utility resulting from consuming an extra unit of that commodity or service.

The marginal utility of a good or service tells about the happiness experienced or the contentment obtained by the consumers as a consequence of the increment or decrement in consumption by one unit.

There exist three kinds of marginal utility. They include positive, negative as well as zero marginal utility.

Which of the following statements is true about dna
Ray Of Light [21]

Answer:

D. The site of transcription is within the nucleus

Explanation:

this is because the process of DNA is converted into RNA

This requires a protein called RNA polymerase. It will copy certain regions of DNA and convert them into RNA (this occurs in the nucleus) and then this RNA goes to the cytoplasm, where it will be translated into a protein.

Therefore, its D.
