Answer: Matter and Energy
Explanation:
The producers make food by the help of the process known as photosynthesis.This is the way by which the energy from the sun is transferred from sun to the plants.
Matter is made and transferred from one tropic level to another tropic level. The organic matter is transferred from the producers to the consumers.
The primary consumer converts energy from them to the secondary consumers.
So, the conclusion is that matter and energy is transferred from one tropic level to another tropic level.
Answer: see explanation
Explanation:
(1). Substainibility actually means finite, renewable etc.
Sustainable resources are natural resources that are renewable and can be harnessed for important things for mankind without short of supply
(2). Water is too cheap, compared to its real value, and is rarely taken into consideration when decisions are made regarding resources. In general, decisions that determine how most of water is utilized are taken by a limited number of people.
(c). Reducing the development of thermal power stations: power station produces 80% of our electricity and consume a lot of water. We can do this by rewarding farmers that uses irrigation farming efficiently.
The answer is 44 chickens and 28 rabbits.
We have a system of two equations.
x - the number of rabbits
y - the number of chickens
Both chicken and rabbit have only 1 head, so the first equation is: x + y = 72.
Since rabbits have 4 legs and chickens 2 legs, the second equation is: 4x + 2y = 200.
Now, let's solve the system:
x + y = 72
4x + 2y = 200
___________
y = 72 - x
⇒ 4x + 2 · (72 - x) = 200
4x + 2 · 72 - 2 · x = 200
4x + 144 - 2x = 200
2x + 144 = 200
2x = 200 - 144
2x = 56
⇒ x = 56 ÷ 2 = 28
So, there are 28 rabbits.
Since
y = 72 - x = 72 - 28 = 44,
there are 44 chickens.
Answer:
Extraction of genomic DNA
Explanation:
Resuspend the cells(any number), smaller numbers also work, in 10-20 ul of TE buffer or milli Q water. boil for 5-10 min in a waterbath, quick chill, short spin. use the supernatant as a template for PCR.
If cells are very less, u can directly add cells to the PCR reaction without enzyme,boil for 5-10 min in a waterbath, let it cool slowly, short spin. Add enzyme to the supernatant and start the reaction at extension step followed by normal PCR reaction steps.
In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis<span>. This occurs when a seed initially situated in an environment of complete darkness is exposed to light. A brief exposure to electromagnetic radiation, particularly that whose wavelength is within the red and far-red lights, results in the activation of the photorecepter phytochrome within the seed. This in turn sends a signal through the signal transduction pathway into the nucleus, and triggers hundreds of genes responsible for growth and development</span>
