Answer: Positive tropism, negative tropism

Explanation:

Stimulus can be define as external and internal agent which generate a response in an organism. If the growth and action is towards the stimulus it is called as positive tropism. If the growth and action is away from the stimulus it is called as negative tropism. Example, the growth of the stem towards the sunlight is called positive tropism whereas the growth of the root away from the sunlight is called negative tropism. Here, sunlight is the stimulus.

While soils are an important part of the global carbon cycle, they are not a part of the nitrogen and sulfur cycles.

Vladimir79 [104]

The correct answer is - False.

The soils are part of most of the major cycles that take place on the Earth, mainly because they are in touch with the other spheres. The carbon dioxide, as well as the nitrogen and the sulfur cycles too, end up in the soil in more cases than not during their cycles. While some are formed in it and than released, like the sulfur, the carbon mostly gets in it though the roots of the plants, as well as the decomposing organisms, and the nitrogen ends up in the soil with the water.

The soil is one of the most important pieces in the cycles of most of the gases on Earth, and without it, some will not even be possible.

some inkjet printers produce picoliter-sized drops. how many water molecules are there in one picoliter of water? the density of

GrogVix [38]

3.37 x 10¹⁰ molecules

Explanation:

Given parameters:

Volume of water = 1pL = 1 x 10⁻¹²L

Density of water = 1.00g/mL = 1000g/L

Unknown:

Number of water molecules = ?

Solution:

To solve this problem, we first find the mass of the water molecule in the inkjet.

Mass of water = density of water x volume of water

Then, the number of molecules can be determined using the expression below:

number of moles = $\frac{mass of water}{molar mass of water}$

Number of molecules = number of moles x 6.02 x 10²³

Solving:

Mass of water = 1 x 10⁻¹² x 1000 = 1 x 10⁻⁹g

Number of moles:

Molar mass of H₂O = 2 + 16 = 18g/mol

Number of moles = $\frac{1 x 10^{-12} }{18}$ = 5.6 x 10⁻¹⁴moles

Number of molecules = 5.6 x 10⁻¹⁴ x 6.02 x 10²³ = 33.7 x 10⁹

= 3.37 x 10¹⁰ molecules

PLEASE HELP ME, 20 POINTS

Marrrta [24]

Explanations:

Question 1: Lithium in 20.00+ g is C. or D., but 25.00+ g is D. which means this is the correct option.

I am unsure of Question 2. I don't think it is mole though.

Question 3: Boron in 25.00-30.00 g is B. or D., but 25.00 g would be C.

Question 4: 2.393 x 1024 atoms of Oxygen is 63.58 mole O. I don't know for sure, but I think this is correct.

I am NOT professional. There is a chance I am incorrect. Please reply to me if I've made a mistake.
