Answer: 100mL sucrose solution and 900mL water
Explanation: sucrose solution is 500 mM, i.e. 500mmol/L
water is 0mmol/L
To get 50mmol/L we need 1/10 L of sucrose solution = 100mL
and made up to 1L with water
The sun is not a living thing. It is made up of gases, such as hydrogen and helium, rather than living cells, which are present in all forms of life
Answer: 1-TT, 2-Tt, 3-Tt, 4-tt
Explanation: It is pretty simple. you just have to match every letter together. Also, the genotype of this is 50% Tt (which is crossbred), 25% TT (which is tall), and 25% tt (which is short).
I hope this helped you out!
there is no clear evidence about plants evolving in the desert, or fossils of any kind of cactus despite their distribution over a large area. But, scientists are of the opinion that they acquired specific attributes millions of years ago, as a response to the vastly changing climate and conditions.
-Desert plant root system
A typical desert plant has a deep root system, which is a specific physical mechanism. As the roots grow deep down the soil, they absorb soil water, which is then transported to the upper portions of the plant.
-Desert plant leaves
Bear small foliage with waxy surface to minimize transpiration (loss of water through stomatal pores), which in turn, helps to conserve water.
Electrical conductivity tester.
If the bulb begins to glow brightly when the plug is submerged in the unknown solution then the solution has high conductivity.
The bright glow of the bulb resulting from the experiment indicates that the current flows easily through the unknown liquid.
