Answer:

So basically the rows are called periods, and the columns are called groups. The groups show that those elements have similar characteristics. There are also different families such as the noble gases and alkali earth metals. The elements are placed where they are because of the atomic number which is directly equal to the number of protons there are. The atomic mass is the number of both protons and neutrons. Also, even though the number of protons can be equal to the number of electrons, that isn't always the case. It could be an isotope which is basically for when an element or atom isn't neutral. Umm, so, I hope this helped. I know it's very long but if you need anything else just ask!! c:

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.

Answer:

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.

Answer:

The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

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:

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:

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.

Explanation: I got it correct on a quiz I did that had this question

Move your hand away. Therefore, option (C) is correct.

A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.

The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

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.

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.

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.

Answer:

ocean gyre

Explanation:

The ocean gyre may be defined as the large system of a circulating ocean currents that is formed as a result of wind patterns globally and by the forces created by the rotation of the Earth. It helps to create a large ocean conveyor belt that helps in circulating the ocean waters in the entire planets. Thus the ocean water keeps a check on the heat of the earth and maintains a balance of heat on the planet.

The ocean gyres makes the movement of the ocean water on the entire globe and thus forms a large loop of the circulating ocean water.
