Answer:
Both can hunt for their food (heterotrophs), but euglena can also make their own food (autotroph) with its chloroplasts. Amoeba have pseudopods to move/eat, but euglena have flagella to move. How are euglena and paramecium similar and different? ... Both also use flagella to move, but volvox move together in colonies.
Explanation:
Answer:
3584.21 J/kg.K
Explanation:
Applying
Q = cm(t₂-t₁)........... equation 1
Where Q = Quantity of heat absorb, c = specific heat capacity of the metal, m = mass of the metal, t₁ = intial temperature, t₂ = Final temperature.
make c the subject of the equation
c = Q/(m(t₂-t₁)........... Equation 2
From the question,
Given: Q = 1362 J, m = 15.2 g = 0.0152 kg, t₁ = 17°C, t₂ = 42°C
Substitute these values into equation 2
c = 1362/0.0152(42-17)
c = 1362/0.38
c = 3584.21 J/kg.K
Endocytosis is a type of bulk transport which involves the movement of large particles through the membrane in and out
Answer:
The element A is S (sulfur)
Explanation:
The elements for the 3erd period in the periodic table are Na, Mg, Al, Si, P, S, Cl and Ar.
The one that has 6 e⁻ in its valence shell is the S, because it is missing 2 e⁻ to reach the octet rule. 2 e⁻ to has the most stable noble gas conformation.
The IE of S = 3360 kJ/mol
It is a little lower than Cl because the electron is so far from the nucleus, that's why we have to apply a very low ionization energy to rip the electron off.
Gay-Lussacs law relates the pressure of gas with temperature when all the other conditions are kept constant.
It states that for a fixed amount of gas, pressure of gas is directly proportional to temperature when the volume is constant.
where P - pressure, T- temperature and k - constant
temperature has been given in Celsius, we need to convert to Kelvin
Temperature in K = Temperature in Celsius + 273.15
1st instance T1 = 35 °C + 273.15 = 308.15 K
P1 = 97 kPa
2nd instance T2 = 75 °C + 273.15 = 348.15 K
P2 - needs to be calculated using following equation
P2 = (97 x 348.15)/308.15
P2 = 110.0 kPa
