The correct answer is 13,800 feet.

Explanation:

30 to 40 feet has an area of 30 x 40 = 1200 sq ft

100 to 150 feet has an ares of 15,000 sq ft.

To get to the answer, you simply subtract 1200 from 15,000 to get 13,800.

Hope this helps! :)

Answer:

Prokaryotic cell-- no organelles, no membrane.

Eukaryotic cell -- Have organelles and membrane.

Explanation:

For the model of prokaryotic cell, we construct the model by removing organelles from the cell whereas in the eukaryotic cell, we add the organelles because in eukaryotic organisms, organelles are present in the cell that performs specific function. In the model of prokaryotic cell, we have to remove membrane around the nucleus whereas membrane president around the nucleus. In the prokaryotic cell, nucleus is not visible while on the other hand, in eukaryotic cell, the nucleus is visible and can be differentiate from other organelles.

Answer:

The actual gas that causes air pollution is called a pollutant

Explanation:

Air pollution is the decrease in air quality. Air pollutants are the gases that cause air pollution.

Pollutants are harmful substances and particles that affect the quality of the environment and are man-made or natural. Fly ash from volcanic eruptions is a natural pollutant that deters the air quality.

The air pollutants like carbon monoxide, sulfur dioxide, and carbon dioxide released from the burning of fossil, coal, and vehicles alter the air quality and result in a change in weather conditions.

Therefore, the pollutants are the actual gases that cause air pollution.

Answer:

Lower Salinity in the ocean water.

Explanation:

The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.

Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.

As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. ... Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases

Answer:

By using carbon-14 in the experiment in order to prove the statement.

Explanation:

Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.

Answer:

If two tectonic plates collide, they form a convergent plate boundary. Usually, one amongst the converging plates will move beneath the opposite, a process called subduction. ... The new magma (molten rock) rises and will erupt violently to make volcanoes, often building arcs of islands along the convergent boundary. When two plates are moving far from one another, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the world and erupts to make new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the method of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges aren't as violent as they're at convergent plate boundaries.

La respuesta correcta para esta pregunta abierta es la siguiente.

A pesar de que se te olvidó incluir las opciones o incisos para responder a tu pregunta, podemos comentar lo siguiente, basándonos en nuestro conocimiento sobre la materia.

Podemos pensar que la hormona que no produce este niño que sufre de gigantismo es la hormona llamada somatotropina. Esta hormona es muy importante durante el crecimiento y desarrollo del niño en la infancia porque secreta la adenohipófisis, una glándula vital para el correcto y proporcionado desarrollo en la etapa de la niñez.

Entonces, si no hay una secreción correcta de la hormona somatotropina, ésta hace que el niño desarrolle la condición llamada gigantismo.

Entonces podríamos decir lo siguiente.

Un estudiante presenta una condición especial llamada gigantismo su altura es mucho mayor que la de los compañeros de la misma edad y se descarta que la causa sea un problema heredero podemos suponer que este estudiante tiene insuficiente de la hormona de crecimiento o somatotropina. Esta hormona no ingresa a las células en su mecanismo de accion por ser una derivación de aminoácidos.

Question:

Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.

Dichotomous Key of Ranunculaceae

#1.

a. Fruit is a group of alkenes.............................. go to step 2

b. Fruit is a group of follicles..............................go to step 4

#2.

a. Petals are not present.....................................go to step 3

b. Petals are present............................................Ranunculus

#3.

a. The flower has 4 sepals.................................. Clematis

b. The flower has 5 sepals................................... Anemone

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium

The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus

Answer:

The species belongs to Delphinium genera.

Explanation:

A dichotomous key is relatively simple to interpret. All you need to do is to:

- carefully observe your organism,

- know some technical terms or have a biological dictionary, and

- follow the descriptions.

The dichotomous key is going to lead you to the answer.

In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.

So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.

#1.

a. Fruit is a group of alkenes.............................. go to step 2.

b. Fruit is a group of follicles..............................go to step 4.

We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium  

We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***
