Answers

Answer: in 1925, people were sick and planes couldn’t land in nome, Alaska. Teams of dogs delivered the medicine

Explanation: I got it right on a quiz

In 1925, people were sick and planes couldn’t land in Nome, Alaska. Teams of dogs delivered the medicine has the most objective tone. Thus, the correct option is D.

What is the objective tone?

Objective tone is an impartial tone. This tone does not show any kind of feelings for or against a topic which therefore, is an unbiased or neutral feeling. The objective tone often uses higher level words and avoids pronouns such as I and you in the sentences, creating a type of formal tone. Subjective tone is a personal, biased, emotional, and often informal kind of tone.

Objective tone refers to an impersonal style of writing, which gives us the information about something however it does not include any information about the writer. So, a sentence like this: "In 1925, people were sick and planes couldn't land in Nome, Alaska. Teams of dogs delivered the medicine" is of the objective tone, Because it just tells us a fact.


Therefore, the correct option is D.

What do you mean by soil fertility?

Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.

A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities, e.g., calcium, magnesium, sulfur, iron.

The following properties contribute to soil fertility in most situations: Sufficient soil depth for adequate root growth and water retention; Good internal drainage, allowing sufficient aeration for optimal root growth.

Answers

Answer:

The absence of ADH is not too dangerous.

Explanation:

If there is no place for the storage of ADH hormone in the pituitary hormones, no death occur of the individual because ADH is related to the conserve of fluid in the blood. If this hormone fails to perform its function properly, it causes the body to retain too much water. This more water retention may cause you to feel heavier than normal, and less active so the person did not die due to the deficiency of this disease.

Cual de estos no se podria observar en un microscopio optico crestas mitocondriales, poros de la membrana nuclear, cromosomas de una celula animal condensados durante la mitosis, las dos capas lipidas que forman la membrana plasmatica

Answers

Answer:

Crestas mitocondriales, poros de la membrana nuclear y las capas lipídicas que forman la membrana plasmática no son visibles al microscopio óptico.

Explanation:

El límite de resolución de un microscopio óptico es de, aproximadamente, de 0,2 μm (es decir 10⁻⁶ m). Es decir, que en un microscopio óptico sólo podrán verse células y estructuras celulares mayores a 0,2 μm, y en algunos casos serán visibles sólo con tinciones especiales.

Por ende, entre las cuatro estructuras que se nos presentan en el problema sólo los cromosomas de una celula animal condensados durante la mitosis pueden verse al microscopio óptico.

Tanto las crestas mitocondriales como los poros de la membrana nuclear y las capas lipídicas que forman la membrana son estructuras muy pequeñas y visibles solamente al microscopio electrónico.
