erosion ___ A) is the same as weathering B) is always a destructive process C) happens more quickly in cold climates than in warm ones D) is the movement of sediment from one location to another

Answers

Erosion is the action of surface processes that remove soil, rock, or dissolved material from one location on the Earth's crust, then transport it away to another location.

So, I think the answer is Letter B: is always a destructive process

The triplet code can produce 64 possible codon combinations. What is an advantage of this? A. Every single codon specifies more than one amino acid. / B. Every single amino acid has more than one codon. / C. The first two bases of the codon specify the amino acid.

Answers

The answer is B. Every single amino acid has more than one codon.

There are 20 different amino acids, but there are more than 20 combinations of three nucleotide bases on DNA. There are 64 different combinations of three nucleotide bases on DNA, which is about 3 times more than the number of amino acids. Therefore, every single amino acid has more than one codon is the right answer. But, it should be taken into consideration, that 2 out of 20 different amino acids have only one codon - methionine and tryptophan.

Which statement represents a fact about the rock cycle?A. All the processes involved in the rock cycle occur beneath the surface of Earth.

B. Fossils, skeletal remains, and living organisms do not play a role in the rock cycle.

C. The rock cycle is driven by energy from the Sun as well as from the interior of Earth.

D. Every transformation between states happens as a result of heat from magma.

E. Nearly all rocks transition from one form to another on a human timescale.

Answers

The answer is : The rock cycle is driven by energy from the Sun as well as from the interior of Earth. The sun provides energy for surface processes such as weathering, erosion, and transport. This is the one of the major source of energy for the rock cycle. Weathering happens when there is a interaction with the air, water and organism which cause the rock to break down, and the pieces of rock are carried away by wind, moving water, etc. through erosion.

Answer: Substitution

Reasoning: In the DNA strand, we have taken a letter out and put in another letter to see what happens. This method is called substitution, when we take something out, and put a new piece in.

A student is examining leaf cells. Which organelle is most likely to be missing from the cells?

Answers

The organelle which is most likely to be missing from leaf cells is Lysosomes.

Lysosomes are an important organelle for eukaryotic animal cells as they contain the digestive enzymes. The macromolecules or foreign matter which are harmful for the cells enter the animal cells easily but not the plant cells as the plant cells contain cell walls. Phagocytosis or digestion of macromolecules is not much needed in plant cells so a lysosome can be missing from the leaf cell.

A cell is the most basic form oflife. It is what most of the organisms are made off. For the organism tofunction, the cell must also function. It has organelles too that helpsfunctions what the microorganisms need. A leaf cell contains chloroplasts thatanimal cells and other cells do not have. The chloroplast is where the photosynthesishappens. It needs sunlight for the process of photosynthesis. Notice that theleaf has a broader surface area to enable them to be exposed to the sun.
