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
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.
Why is it dangerous to a fetus for the pregnant mother to drink alcohol?
If the pituitary is so important and Eric is not getting replacements of hormones the pituitary makes (except for ADH), why isn’t he dead? To answer this question, think through the cascade of events from hypothalamus to effect.
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.

What is the probability of the offspring having red-green color blindness for the cross that is represented by the Punnett square?
0 percent
25 percent
50 percent
75 percent
Answer: 25%
Explanation: This is the correct answer on Edge 2020 (just took the unit test review and made a 100%) ^-^.
X-linked recessive disorder refers to the genetic condition in which mutations or errors are associated with the gene are present on the X chromosome. The male will be affected by the disorder, while the females can be carriers.
In the given Punnett square, there is a 25% chance that the offspring can be -red-green color blind.
Red-green color blindness in people refers to the difficulty in distinguishing the colors like red, green, orange, and yellow. People with color blind have a normal life and there is no proper cure for the condition.
Thus, the percentage of the offspring that will be red-green color blind is 25%.

Which of the following best describes soil fertility?
O An inexpensive way to maintain plant health and maximize crop productivity
O The amount of nutrients available in a soil
O A measure of soil quality which stays constant throughout a growing season
O The quality or ability of a soil to provide nutrients to plants
Answer:
O the amount of nutrients available in soil
Explanation:
good answer
Measure of soil quality which stays constant throughout a growing season is best describes the soil fertility.
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.

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.
