How does photosynthesis start?
Which is one factor that contributes to the formation of polar, temperate, and tropical zones?
the angle of the Sun's rays
the direction of seasonal winds
the presence of prevailing winds
the movement of wind near a mountain
The one factor that contributes to the formation of polar, temperate, and tropical zones is the angle of the Sun's rays. Thus, option "A" is correct.
What is the climatic condition of tropical zones?The climate on Earth can be divided into three major zones, tropical, temperate, and polar.
The tropical ones are at the Equator and near to it, the temperate ones are at the mid-latitudes, and the polar ones are at the higher latitudes.
This is a result of numerous factors, such as the shape of our planet, as the sunlight falls at different angles at different parts of it, so some parts get much more heat, while some much less.
Thus, option "A" is correct.

One factor that contributes to the formation of polar, temperate, and tropical zones is the angle of the Sun's rays. The angle of the Sun's rays determines the amount of solar energy that reaches a particular region.
What is the cause of formation of polar?This is due to the Sun's rays, which are more oblique in the northern regions and more direct in the tropics. The length of the day in a specific location is also influenced by the Sun's rays' angle. The duration of the day is longer in the tropics than in the polar regions, and this directly affects the local temperature.
The Sun's rays are directed more directly and at higher angles, which results in higher temperatures. Predominant winds also aid in the development of the arctic, temperate, and tropical zones. Predominant winds move warm air from the equator to the poles and vice versa, which has an impact on a region's temperature.
The temperature of an area is also influenced by the direction of the predominant winds. For instance, temperatures in the area will be lower if the predominant winds are from the east than if they are from the west. Predominant winds have an impact on the amount of moisture in the air, which can change a region's climate.
Polar, temperate, and tropical zones can also occur as a result of wind movement close to mountains. This is so that the mountain and the surroundings won't be separated by the wind.

Why is it important to know the difference between science and pseudoscience? to look intelligent to make informed decisions to score well on tests to tell believable stories
Answer:
The difference between science and pseudoscience is that science organizes knowledge in testable explanations and predictions about the universe while a pseudoscience is a claim or a belief which is carried out as scientific but has no valid.
Explanation:
It is important to know the difference between science and pseudoscience because it helps in telling believable stories to people who do not have this sense of understanding and still have myths in their mindsets. Thus, the correct option is D.
What is Pseudoscience?Pseudoscience may be defined as the collection of claims and assertions that are presented as science but that lack valid facts or conclusions based on scientific methods.
If you know the exact differences between both terms, then only you should communicate with others and spread the knowledge in place of ancient concept and mythology.

Advantages of using ethanol as fuel
A. It is a carbon-neutral activity
C. It does not produce toxic gases when burnt
D. It can be mixed with conventional petrol to make gasohol
Disadvantages
B. It takes a lot of plant materials to produce the ethanol
Explanation:
It has been proven that blending ethanol with conventional petrol produces gasohol and this helps to reduce the harmful emissions of CO, hydrocarbons, etc. This then means that vehicles that run on ethanol produces fewer harmful emissions than those that run on gasoline. For ethanol, it produces a no net carbon dioxide emissions.
Ethanol is considered to be atmospheric carbon neutral when the combustion of ethanol is made from biomass (such as sugarcane and corn). Ethanol is made plant materials like grains and crops that possess high starch. Also, it can be made from sugar content such as sugar cane, sorghum, corn, barley and sugar beets.

Describe how the light-independent reactions of photosynthesis/ respiration work. Describe what happens in the light-dependent part of the cycle compared to the light-independent part of the cycle (light reaction/dark reaction)
Answer:Photosynthesis in desert plants has evolved adaptations that conserve water. In harsh, dry heat, every drop of water must be used to survive. Because stomata must open to allow for the uptake of CO2, water escapes from the leaf during active photosynthesis. Desert plants have evolved processes to conserve water and deal with harsh conditions. A more efficient use of CO2 allows plants to adapt to living with less water.
Some plants such as cacti can prepare materials for photosynthesis during the night by a temporary carbon fixation and storage process, because opening the stomata at this time conserves water due to cooler temperatures. In addition, cacti have evolved the ability to carry out low levels of photosynthesis without opening stomata at all, a mechanism for surviving extremely dry periods.
image
Cactus: The harsh conditions of the desert have led plants like these cacti to evolve variations of the light-independent reactions of photosynthesis. These variations increase the efficiency of water usage, helping to conserve water and energy.
CAM Photosynthesis
Xerophytes, such as cacti and most succulents, also use
phosphoenolpyruvate (PEP) carboxylase to capture carbon dioxide in a process called crassulacean acid metabolism (CAM). In contrast to C4 metabolism, which physically separates the CO2 fixation to PEP from the Calvin cycle, CAM temporally separates these two processes.
CAM plants have a different leaf anatomy from C3 plants, and fix the CO2 at night, when their stomata are open. CAM plants store the CO2 mostly in the form of malic acid via carboxylation of phosphoenolpyruvate to oxaloacetate, which is then reduced to malate. Decarboxylation of malate during the day releases CO2 inside the leaves, thus allowing carbon fixation to 3-phosphoglycerate by RuBisCO. Sixteen thousand species of plants use CAM.

How does an iron nail change after being exposed to the oxygen in the air over a long time? Question 24 options: It burns It decays It molts It rusts
Answer:
It rusts
Explanation:
Iron is a chemical element that has the ability to RUST when exposed to air and water. Rusting is actually a prolonged chemical process or change that results when iron reactively combines with water and oxygen in the atmosphere to from hydrated (III) oxide in a process called OXIDATION. This compound is behind the color change of the metal.
According to this question, a nail made of iron will change after being exposed to the oxygen in the air over a long time by RUSTING via the oxidative reaction of the iron constituent of that nail with oxygen.

Write characterize progression of infectious disease.
Answer:
* Infectious disease management depends on precise portrayal of disease progression so transmission can be forestalled. Gradually progressing infectious diseases can be hard to characterize because of a latency period between the time an individual is infected and when they show clinical signs of disease.
* Defining directions through sickness states from infection to clinical illness can assist researchers with creating control programs dependent on focusing on individual infection state, possibly decreasing both progression and creating misfortunes because of the illness.
Explanation:
Gradually progressing infectious diseases are hard to characterize in light of the fact that they are frequently connected with an inactivity period between the time an individual is infected and when they give clinical indications or side effects of illness.
To successfully control infectious diseases, it is paramount to see how the disease progresses.
