What type of surface makes water turn into run-off? what happens when enough run-off water gathers to flow farther downhill? PLS HELP

Answers

Answer 1
Answer:

Answer:

A surface like a mountain.

Explanation:

The mountain cannot absorb the water and when snow melts it wil run down the mountain.
Answer 2
Answer: An uneven surface. When enough water gathers to move further downhill, the water overflows and while the water is going downhill, it can also cause erosion.

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.

vines and trees are both plants but, they are very different from each other. what adaptations can you see in these plants, and how do you think these adaptations help them survive

Answers

trees have well-developed roots and leaves.
vines can crawl in walls and other trees that catches better sunlight and rainwater. 

Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time.

Which type of reaction listed below is an example of an anabolic reaction ? (Hint : which equation represents photosynthesis?)

Answers

The process of converting carbon dioxide and water into sugar molecules, photosynthesis is 6CO₂ + 6H₂O→ C₆H₁₂O₆ + 6O₂, hence option A is correct.

What is photosynthesis reaction?

Such as sugars, and storing this chemical energy is known as photosynthesis which indicates that the products, a sugar molecule, and six oxygen molecules, are created.

Green plants and a few other species create their food through a process called photosynthesis, which involves the utilization of water, carbon dioxide, and sunshine.

When light energy is absorbed by chlorophyll (implied by the arrow) from the reactants, six carbon dioxide molecules, and six water molecules.

Plants, algae, and certain microorganisms employ the process of photosynthesis to transform light energy into chemical energy.

Therefore, the commonly used notation for photosynthesis is 6CO₂ + 6H₂O→ C₆H₁₂O₆ + 6O₂, hence option A is correct.

  • Recombinant DNA technology

Recombinant DNA technology is a part of genetic engineering whereby the DNA molecule from different species are fused together ( I.e. DNA  molecule is taken from a donor and inserted into the DNA of the host ).  

The process is carried out in order to produce a desired genetic combinations/trait in the offspring produced. which will be beneficial to science and other fields as required ( mostly agriculture and medicine ).

Hence we can conclude that the process is called Recombinant DNA technology.
