Answer:
mitochondria because it provides the cell with energy
Answer:
Look below plz :))
Explanation:
1.) In a chemical change, the molecules in the reactants interact to form new substances. In a physical change, like a state change or dissolving, no new substance is formed. Explain that another way to say that no atoms are created or destroyed in a chemical reaction is to say, “Mass is conserved.”
2.) Carbon Dioxide and Water Out: During combustion, the atoms in ethanol and oxygen are rearranged into carbon dioxide and water. The carbon dioxide and water leave the top of the flame.
Supose the material of the skillet is iron.
The specific heat constant for iron is:
Since the unit of measurement for the specific heat constant is Joules per kilogram Kelvin, we transform the temperatures from degrees Celsius to degrees Kelvin:
T1 = 12 °C = 273.15 + 12 = 285.15 K
T2 = 84 °C = 273.15 + 84 = 357.15 K
We also convert the mass from grams to kilograms:
m = 46 g = 0.046 kg
The amount of heat absorbed by the skillet is:
Replacing the above values, we get:
The answer is 1557 J (joules) or 1.557 kJ (kilojoules).
If the material is aluminium, use the specific heat of aluminium in your calculation, which is:
Answer:
Carrying capacity is the maximum population of species an ecosystem can sustained with the various necessities needed for survival. An ecosystem comprising of sea title species and has its carrying capacity, will give sea title acess to adequate food, water, shelter, mates e.t.c. These are basic necessities for organisms survival. Once sea title have access to these, it will be preserved and life without been disturbed, prey on or compete for limited resources because resources are available for it's uses.
Explanation:
The carrying capacity of an ecosystem refers to maximum population of species an ecosystem can sustain with it's available resources for survival. The population size is limited by factors like food, water supply, space, shelter, mates e.t.c. A population depends on various components of it's ecosystem for nececities like food, water, space , mates e.t.c. An ecosystem can only support a given population and if it's exceed it carrying capacity, competition, predation and parasitism will set in.
