The two ways that the human population change as a result of the agricultural revolution are:

1. Use of Iron technology. Some of the benefits of iron technology in agriculture include iron has replaced the use of steel and plows and there was no further need to domesticate any other animals. Iron technology has made the lives of farmers in agriculture easier and faster due to iron technology.

2. Use of GMO. To protect plant form insect damage, it can be made intoa transgenic plant. Transgenic plant are called genetically modified organisms (GMO) because there is a gene added or removed in the original plant to obtain a characteristic that would enhance the plant's production such as insect damage.

What are restriction enzymes? what are restriction enzymes? exonucleases that degrade single-stranded dna endonucleases that ran

tangare [24]

Restriction enzymes, also known as restriction endonucleases, are enzymes that cut a DNA molecule at a particular place. They are essential tools for recombinant DNA technology. The enzyme "scans" a DNA molecule, looking for a particular sequence, usually of four to six nucleotides.

In the figure below, ΔMNO≅ΔPQR.What is the measure of ∠P? Show your work and explain your reasoning.

Juliette [100K]

Answer:

$\huge\boxed{\sf P = 79.5\°}$

Explanation:

Given that:

ΔMNO ≅ ΔPQR

That means

M ↔ P

N ↔ Q

O ↔ R

So,

∠P ≅ ∠M

Given that P = 3x + 20.4 and M = 5x - 19

3x + 20.4 = 5x - 19

Add 19 to both sides

3x + 20.4 + 19 = 5x

3x + 39.4 = 5x

Subtract 3x to both sides

39.4 = 5x - 3x

39.4 = 2x

2x = 39.4

Divide both sides by 2

x = 19.7

Given that:

P = 3x + 20.4

P = 3(19.7) + 20.4 (x = 19.7)

P = 59.1 + 20.4

P = 79.5°

compare and contrast the processes of photosynthesis and aerobic respiration. how are they similar and how do they differ?

Brut [27]

Answer:

Explanation:

Photosynthesis and cellular respiration (aerobic) are both metabolic processes that occur in specialized organnelles of living cells. These two processes are so unique to one another in the sense that one uses the product of the other as a reactant and vice versa.

Photosynthesis is an anabolic reaction that occurs in the Chloroplast of autotrophs in which captured energy from sun is used to synthesize organic food (glucose) by combining carbondioxide (CO2) and water. Oxygen is released in this photosynthetic process.

6CO2 + 6H20 --------> C6H12O6 + 6O2

Aerobic cellular respiration, on the other hand, is a catabolic process undergone by every aerobic living cell (in the mitochondria) in which glucose is broken down in the presence of oxygen to produce ATP (energy) releasing CO2 and water (H2O) in the process.

C6H12O6 + 6O2 ------> 6C02 + 6H2O

One spectacular difference is that photosynthesis uses solar energy (from sun) while aerobic cellular respiration uses chemical energy to power the process.

Answer:

Evidence of metamorphism can be indicated by flat, horizontal layers within the rock.

Explanation:

Metamorphic rocks refer to rocks that are modified with heat or pressure, which change their physical and chemical properties. The main reason behind this modification is the rearrangement of the mineral crystals, which occurs due to their response to the previously-mentioned properties of heat and pressure.

There could be different types of evidence of metamorphism. However, the main evidence can be indicated by the presence of flat, horizontal layers within the rock, also known as foliation, a process that occurs when the pressure squeezes the minerals, leading to a flat, horizontal layer. Then, scientists could analyze the composition of these layers to identify minerals or even fossils within it.
