Answer:

Corn

Explanation:

Being a plant and having chlorophyll in its structures, corn is able to capture sunlight and converting it into chemical energy, through photosynthesis.

Photosynthesis is a process carried out by plants to produce their own food. The plant draws carbon dioxide from the air and energy from the sun. Through this process, the plant produces its own food consisting essentially of glucose.

Briefly, we can say that photosynthesis uses carbon dioxide, water and sunlight (in the form of heat) to produce organic compounds (glucose) and oxygen.

What is a single celled organism able to do? survive on its own make tissues grow to large sizes differentiate
bekas [8.4K]

Within multicellular organisms, tissues are organized communities of cells that work together to carry out a specific function. The exact role of a tissue in an organism depends on what types of cells it contains. For example, the endothelial tissue that lines the human gastrointestinal tract consists of several cell types. Some of these cells absorb nutrients from the digestive contents, whereas others (called goblet cells) secrete a lubricating mucus that helps the contents travel smoothly.

However, the multiple cell types within a tissue don't just have different functions. They also have different transcriptional programs and may well divide at different rates. Proper regulation of these rates is essential to tissue maintenance and repair. The spatial organization of the cells that form a tissue is also central to the tissue's function and survival. This organization depends in part on polarity, or the orientation of particular cells in their place. Of course, external signals from neighboring cells or from the extracellular matrix are also important influences on the arrangement of cells in a tissue.

Which distinguishes a dwarf planet from a planet?
Rashid [163]

Answer:

It's size

Explanation:

The definition of a dwarf planet is "a celestial body that orbits the sun and has a spherical shape but is not large enough to disturb other objects from its orbit"

Essentially, "dwarf" is an adjective. Just like saying the colour distinguishes a purple planet...

. The Henry's law constant for helium gas in water at 30 ∘C is 3.7×10−4M/atm; the constant for N2 at 30 ∘C is 6.0×10−4M/atm. a.
ludmilkaskok [199]

Explanation:

1) Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

M_{g}=K_H\times p_{g}

where,

K_H = Henry's constant

p_{He} = partial pressure of gas

a)  K_H=3.7\times 10^{-4} M/atm

p_{He}=2.1 atm

Putting values in above equation, we get:

M_{He}=3.7\times 10^{-4} M/atm\times 2.1 atm = 7.77\times 10^{-4} M

The solubility of helium gas is 7.77\times 10^{-4} M

b)  K_H=6.0\times 10^{-4} M/atm

p_{N_2}=2.1 atm

Putting values in above equation, we get:

M_{He}=6.0\times 10^{-4} M/atm\times 2.1 atm = 1.26\times 10^{-3} M

The solubility of nitrogen gas is 1.26\times 10^{-3} M

2)

a) Mass of solute or methanol , m= 14.7 g

Mass of solvent or water , m'= 186 g

Mass of the solution = M = m + m' = 14.7 g + 186 g = 200.7 g

w/w\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100

=\frac{14.7 g}{200.7 g}\times 100=7.32\%

The mass percent of methanol is 7.32%.

b) Molality is defined as moles of solute per kilograms of solvent.

m=\frac{\text{Moles of solute}}{\text{Mass of solvent in kg}}

Moles of methanol = \frac{14.7 g}{32 g/mol}=0.4594 mol

Mass of solvent = 186 g = 0.186 kg

m=\frac{0.4594 mol}{0.186 kg}=2.4610 mol/kg

The molality of methanol is 2.4610 mol/kg.
