What landscape feature contributes to the dryness of deserts?
A. The open, flat areas of a desert prevent clouds from forming.
B. Desert canyons collect all water and funnel it out of the desert.
C. Desert lakes absorb all the water.
D. Mountains block the winds that bring rain clouds.
Answer:
As I'm Not % Sure I Can Say C & D don't seem Right, Leaving A & B Having Me to Think the Answer is A (Hope I'm Right Good-Luck)
Explanation:
Answer: Mountains block the winds that bring rain clouds.
Explanation: By acting as obstacles to the flow of air masses, mountains contribute significantly to the dryness of deserts. Orographic lifting is a process that occurs when moist air is forced to ascend as it approaches a mountain range. The moisture in the air condenses and forms clouds as the air cools as it climbs. As a result, on the windward side of the mountains, the air loses a lot of its moisture as precipitation. The air has already lost a significant amount of moisture by the time it reaches the leeward side of the mountains, creating a rain shadow effect. On the leeward side of the mountains, this impact results in a dryer area that is often a desert. Consequently, the existence of mountains influences

Answer: Genes are transcribed into RNA molecules, which are then translated into proteins.
Explanation: Genes are sections of DNA that contribute to certain traits, characteristics or functions. Genes code for proteins or parts of proteins that influence things like the immune system, skin pigmentation, hormone production, and eye color.
Answer:
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.

Explanation:

Answer:
If I were to be a scientist, I'd be a botanist. A botanist is a scientist who studies plants. For example, they study many different aspects like their genetic, physical structure, and the distribution. They also study the relationship between plants and their different environments.
I would choose to be a botanist, because they help save our plants which are very important. They also help with telling others what exactly causes pollution and possible ways to stop it. Botanist also help with providing human resources like food. Without botanist, we would have a lot less of resources that we use in everyday life.
I can see my life as a botanist in many different ways. I might be put in the chemical based section or I might be put in the analysis of plants. Overall if I were to see myself as any kind of scientist, It would have to be a botanist.

What are the phases of matter and the properties of each phase?
Answer:
The Phases of Matter are Solid, Liquid, and Gas. With Plasma as an exception. Solids are defined by their structural stiffness and resistance to form or volume changes. A liquid is a compressible fluid is one that adapts to the geometry of its container while maintaining a consistent volume regardless of pressure. Gas compresses easily, expands to fill containers, and takes up significantly more space than the liquids or solids from which it is formed. Plasma has no fixed shape or solid volume just like gas. That's the best I can explain, hope you find it helpful!

Which is a strong base? HCl NaOH NH3 H3CO3
Answer:
Its B
Explanation:
The answer above this one is right.
The strong acid and strong base has high rate constant of dessociation. Weak acid and base are the one whose rate constant for the dissociation is low, they do not dissociate readily in water. Therefore the strongest base among all is NaOH
What are acid and base?Acid is a solution which releases H⁺ hydrogen ion when dissolved in water. Base are the solution which relaeases hydroxide ion OH⁻ ion when dissolved in water
According to our question we are given four solutions HCl, NaOH, NH₃, H₃CO₃. Out of which HCl and H₃CO₃ are the acids as they release hydrogen ion in water. NaOH and NH₃ are base.Out of which NaOH is the one which readily give hydroxide ion when dissolved in water
Therefore the strongest base among HCl, NaOH, NH₃, H₃CO₃ is NaOH

Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its ---------------- energy increases and its ---------------------------- decreases.
Answer:
Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its -------Potential --------- energy increases and its -----------kinetic----------------- decreases.
Explanation:
Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. ... As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

Explanation:
What is the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis according to the balanced equation: 2H2O yields 2H2 + O2
Taking into account the reaction stoichiometry, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.
Reaction stoichiometryIn first place, the balanced reaction is:
2 H₂O → 2 H₂ + O₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
H₂O: 2 molesH₂: 2 molesO₂: 1 moleThe molar mass of the compounds is:
H₂O: 18 g/moleH₂: 2 g/moleO₂: 32 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
H₂O: 2 moles ×18 g/mole= 36 gramsH₂: 2 moles ×2 g/mole= 4 gramsO₂: 1 mole ×32 g/mole= 32 gramsDefinition of theorical yieldThe theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
Theorical yield of O₂The following rule of three can be applied: if by reaction stoichiometry 36 grams of water form 32 grams of oxygen, 29.2 grams of water form how much mass of oxygen?
\(mass of oxygen=\frac{29.2 grams of waterx32 grams of oxygen}{36 grams of water}\)
mass of oxygen= 25.956 grams
Finally, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.

Why do some animals die off while other similar animals survive in the same environment?
Answer:
Extinction is often caused by a change in environmental conditions. When conditions change, some species possess adaptations that allow them to survive and reproduce, while others do not. If the environment changes slowly enough, species will sometimes evolve the necessary adaptations, over many generations.

What is the kinetic energy of the 2 kg ball just before it hits the ground, travelling 28 meters per second?
Use this formula: KE=0.5mv²
Kinetic Energy (KE) is measured in Joules (J)
Mass (m) is measured in kilograms (kg)
Velocity (v) is measured in meters per second (m/s)
A) KE = 0.5 x 28 x (2)2 = 556 J
B) KE = 0.5 x 2 x 28 x 2 = 56 J
C) KE = 0.5 x 2 x (28)2 = 784 J
D) KE = 28 x 2 x (0.5)2 = 14 J
Answer:
The correct answer is C) KE = 0.5 x 2 x (28)2 = 784 J.
This is because the kinetic energy of an object is equal to one half times the mass multiplied by velocity squared.
In this case, the mass of the ball is 2 kg and the velocity is 28 m/s, so the equation would be KE = 0.5 x 2 x (28)2 = 784 J.
Answer:
KE = 784 J
Explanation:
ke= 0.5x2kgx28m/s
