Which organism in the food chain is
responsible for transforming radiant
energy into chemical energy?
Grass->Prairie Dog -> Coyote -> Soil Bacteria
Answer:
The organism in the food chain responsible for transforming radiant energy into chemical energy is;
Grass
Explanation:
Radiant energy is the energy present in electromagnetic waves which carry photons that may be considered as energy packets. It is an energy present in the Sunlight, which is an electromagnetic waves, and it is the energy in the electromagnetic waves that plants convert to chemical energy for food in the process known as photosynthesis as follows;
6CO₂ + H₂O + Radiant energy → C₆H₁₂O₆ + 6O₂
Therefore the organism in the food chain responsible for transforming radiant energy into chemical energy is the plant, grass
Why is a pyramid shape used to represent the energy in an Ecosystem?
Answer:
An energy pyramid shows the flow of energy at each trophic level in an ecosystem. A pyramid shape is used because energy is lost at each trophic level when organisms use it up.

Jay painted the inner four walls of a box. Then he put an ice block into it such that it did not touch the walls, but he couldn't do the same when he put water in that box. Why?
Answer:
Liquid takes the shape of container, so it will always touch the walls of the box in which you put it.
Explanation:
We know that a solid has a definite shape and a definite volume hence it occupies only its own volume in the box, it does not touch the walls of the box.
However, a liquid does not have a definite shape and volume. It occupies the volume of the box. Therefore, the liquid water must definitely touch the walls of the box.
A gas at a pressure of 360 torrs and a volume of 750 ml. If the pressure becomes 1.5 atm what is the new volume?
Answer:
V₂ = 236.84 mL
Explanation:
The relation between pressure and volume is inverse.
We can write it as follows :
[tex]P_1V_1=P_2V_2[/tex]
We have,
P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.
So,
[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]
So, the new volume of the gas is 236.84 mL.
What are the end products of anaerobic respiration in yeast cell ?
Answer:
glucose ethanol and co2
please follow me and mark it brainliest
Answer:
In anaerobic respiration yeast breaks down glucose, forming ethanol and carbon dioxide as its waste products. When the glucose is nearly used up, and provided that oxygen is present, yeast uses the ethanol as a respiratory substrate to produce carbon dioxide and water in aerobic respiration.

In a 63.17 g sample of SOs, how many grams are sulfur?
Answer:
25.30 gram
Explanation:
No of moles = given mass / molar mass
No of moles = 63.17/80.06
0.7890 moles
Mass of sulphar = no of moles× molar mass of sulphar
Mass of sulphur = 0.7890×32.065
25.30 gram
Which of the following correctly describes the difference (on average) between an electron in a 2s orbital and an electron in a 3s orbital?
Answer:
C: electrons is the 3s orbital are higher than those in the 2s orbital
Explanation:
Looking at the options, the correct one is that the electrons in the 3s orbital will possess more energy than those in the 2s orbital. This is because the the 2s orbitals will be filled with electrons first before the 3s orbital.
Also from basics we know that the energy of an orbital increases as the quantum number increases.

2. How much force, in g cm / s2 , is exerted by a golf ball described in problem 1 striking a tree while accelerating at 20 cm / s2 ? Show how you can solve this problem without knowing that F = m a. Explain your solution.
Answer:
F = 1000 g cm/s²
Explanation:
Let the weight of 1 ball is 50 gram
Acceleration, a = 20 cm/s²
We need to find the force exerted by a golf ball. We know that,
F = ma
So,
F = 50 g × 20 cm/s²
F = 1000 g cm/s²
So, the required force is 1000 g cm/s².

A tank for storing liquid as a base of area 1.5 meters square. What is the pressure on the base of the tank when it contains water weighting 4500n
Answer:
3000 Nm^2
Explanation:
We must remember that pressure is defined as force per unit area.
We have been given the following information in the question;
Area of the tank= 1.5 m^2
Weight of water in the tank = 4500N
And;
P = F/A
F= force
A = area
P = 4500 N/1.5m^2
P= 3000 Nm^2

Determine el número de moles presentes en una esfera de titaniode 0.5 cm de radio, sabiendo que la densidad del titanio es de 4507kg/m³. =433
Answer:
0.0493 moles de Titanio
Explanation:
Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:
Volumen de la esfera:
Volumen esfera = 4/3π * Radio³
Volumen = 0.5236cm³
En m³ (1m³ = 1x10⁶cm³):
0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³
Masa en gramos:
5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio
Moles -Masa molar Ti: 47.867g/mol-:
2.36g de Titanio * (1mol / 47.867g) =
0.0493 moles de TitanioAgNO3 (aq) +

If an object has a Mass of 11g and a volume fo 13mil, what is its density?
A.143g/ml
B.0.85g/ml
C.2g/ml D.24g/ml
Answer:
[tex]\boxed {\boxed {\sf B. \ d \approx 0.85 \ g/mL}}[/tex]
Explanation:
Density is found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the object is 11 grams and the volume is 13 milliliters.
[tex]m= 11 \ g \\v= 13 \ mL[/tex]
Substitute the values into the formula.
[tex]d= \frac{11 \ g}{13 \ mL}[/tex]
Divide.
[tex]d=0.846153846 \ g/mL[/tex]
Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 4 to a 5.
[tex]d \approx 0.85 \ g/mL[/tex]
The density is about 0.85 grams per milliliter.

A. Sound has longer wavelengths than light
B. Light has a greater mass than sound
