are the most reactive nonmetals.
16. The elements in group_
are very unreactive.
17. The elements in group_
react very violently with water.
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.

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***

C: Converting radiant energy into chemical energy.
Explanation:
Only plants (producers) in a typical ecostystem can convert radiant energy into chemical energy.
Answer:
Converting Radiant energy into Chemical energy.
Explanation:
There are two main purposes for plants. 1. Providing oxygen 2. serving as producers. As we know, plants take in the sunlight from the sun and make glucose with it. This glucose in its form is chemical energy that benefits both the plants, or the consumers that eat them, or some parts of the plant. It does not talk about oxygen or atmosphere except for nitrogen, which they actually get from the ground. Therefore, Converting Radiant energy into Chemical energy would be the right answer.

What effect did an increasing human population have on the sustainability of a managed ebony forest?
A)The ebony forest population increased when managed, even as the human population grew. As the human population grew, forest management caused more trees to be produced.
B) The ebony forest population remained stable when managed, even as the human population grew. Forest management allowed more trees to be grown.
C) The ebony forest went extinct. As the human population grew, it was not possible to maintain the forest, even when it was managed.
The ebony forest went extinct. As the human population grew, it was not possible to maintain the forest, even when it was managed. That is option C
Forest is one of the renewable resources that needs to be conserved.
This is because the importance of forest to humans, wildlife and the soil can not be over emphasized.
Their benefits include:
They provide a protective cover for the soil against the action of wind and rain.They act as wind-breaks, reducing wind speeds and checking the erosion of the surrounding land.They provide homes for wildlife.When there is increase in human population, the chances of a conserved forest like ebonyi forest to survive is diminished.
This is so because, with the increased population there will be:
Increased demand for timber,Clearing of forest for growing crops, Setting up industries, building roads and houses.Therefore, the government may be forced to clear the forest to attend to the needs of the growing population. This can cause the ebonyi forest to go extinct.

A group of students were interested in showing photosynthesis occurring visually. They decided to use bromothymol blue which is an indicator that turns green when there is a high concentration of carbon dioxide and blue when there is a low concentration of carbon dioxide in water. All the tubes started out blue, but students blew carbon dioxide into two of the test tubes turning them green. They left one test tube of each color as their control and put a piece of aquatic plant in the other two tubes. Then, they put all four of these tubes outside (Monday 7 am). When the students checked their tubes in the afternoon (Monday 1 pm), they were so excited to see that tube D had turned blue! Carbon dioxide was going away and being replaced with oxygen. When the students checked their experiment early the next morning, tube B and D had both turned green! Did photosynthesis occur during the experiment? Support your claim with evidence explain your reasoning.
Answer:
photosynthesis did not occur.. because if photosynthesis had occured oxygen would be produced..but the tubes turned green proving there was more carbondioxide than oxygen Which proves photosynthesis didn't take place.
hope my ans helps
be sure to follow me
stay safe
have a good day
As the test tube turned green, it means that photosynthesis did not occur in the test tubes.
What is bromothymol blue?Bromothymol blue (BMB) is a dye that turns yellow when exposed to acid. When carbon dioxide is added to a solution, it produces carbonic acid, which lowers the pH.
When the pH is greater than 7.6, BMB is blue, green when the pH is between 6-7.6, and yellow when the pH is less than 6.
Carbon dioxide dissipates in water to produce a weak acid. As a result, an acid-base indicator like bromothymol blue (BTB) can be used to detect the presence of CO2.
The person basically use bromothymol blue as an indicator to determine how much CO2 remains in test tubes containing light-exposed plants.
Thus, as there were some drawbacks in the experiment, the test tube B and D got green color, which means the level of carbon dioxide were more. This implies, photosynthesis did not occur.

How are photosynthesis and cellular respiration connected as a cycle?
Answer:
Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off).
glucose + oxygen + (energy) → carbon dioxide + water
C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O
Respiration is the process of producing energy from glucose. It uses glucose and oxygen to give water, carbon dioxide and energy (thus making it exothermic).
carbon dioxide + water + energy → glucose + oxygen
6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2
As you can see from the equations, they are essentially the reverse of each other.
Another difference is how they are used. Respiration occurs in the mitochondria of all living cells, whereas only plants photosynthesize.
In plants, they make their own glucose using the sun's energy, then respire to allow them to use the glucose for the energy they can use. The glucose can also be stored and used in many other ways other than in respiration.
