Answer:
14 Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
15 The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.
16 Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
17 Group 1: Alkali Metals
Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water.

WHAT IS The 2nd phase of mitosis
Answer:
When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.

pls help i need answer asap! The digestive system is a group of organs working together to convert food into energy and basic nutrients that are transported throughout the body. Food passes through a long tube inside the body known as the alimentary canal, made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Once food is chewed, the bolus is moved into the stomach for further digestion. Examine the Interconnections chart and select the body system that is responsible for moving the food from the start to the finish of the digestive system.

Plant cells have chloroplasts.Plant cells have one large vacuole, while animal cells have several smaller vacuoles.Plant cells have cell walls.CELL:
Cell is regarded as the basic and fundamental unit of life according to the cell theory. Every living organism must possess a cell, which contains organelles responsible for performing specific tasks. Cells of plants and animals are different in some ways and similar in other ways. Some of the true facts about plant and animal cells in accordance to this question are:Plant cells have chloroplasts while animal cells do not. This is why plant cells can synthesize their own food via photosynthesis. Plant cells have one large vacuole located at the centre of the cell while animal cells have several smaller vacuoles scattered throughout the cell.Plant cells have cell walls while animal cells do not. The cell wall of plants is made up of cellulose and gives the cell shape and strength.

What happens when plates meet? (4 complete sentences minimum)
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.

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
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.
Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.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***

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.

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.
