Mercury, Venus, Earth, Mars, and the earth's moon have similar compositions and densities. These planets are close to the sun, rocky, and dense.
There 2 ways to solve this
1- Directly :
80% of water in the fresh berries è 20% of water in the dried berries
36 Ibs of the fresh berries è X Ibs of the dried berries
X =
<span> = 9 Ibs</span>
<span>2- </span>If you do not understand the first method, the second one is more explicit:
First, we gonna calculate the weight of the berries without water (dehydrated):
<span>36 * 80% = 28.8 Ibs (of water in the berries)</span>
Then:
<span>36 – 28.8 = 7.2 Ibs (of completely dehydrated berries)</span>
Next, we gonna add 20% of water in the dehydrated berries:
X (total weight of dried berries) è 100%
7.2 Ibs of dehydrated berries è 80%
X = <span> </span>
= 9 Ibs
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,

Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,

Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,

If V = 2V and p = 2P
Then,


Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
A male lizard will do this to attract a mate.
The group of choices is as follows:
Proteins' primary function is to provide energy to cells.
Lipids' unique 3D structure determines their function.
Nucleic acids are critical components of plant cell walls.
Carbohydrates include glucose, a critical molecule for cellular respiration
Answer:
The correct answer is - Carbohydrates include glucose, a critical molecule for cellular respiration
Explanation:
Macromolecules are the large molecules of nutrients that are made by the polymerization of monomers or smaller subunits and perform various cellular functions. These molecules are protein, carbohydrate and nucleic acids.
The biological function of these molecules is not limited but they have different primary functions and among the given group of choices the best function is carbohydrate perform cellular respiration to produce energy as its primary function to provide energy to cells.
