The correct answer is a rodent that sleeps underground during day
A desert rodent such as kangaroo rat well adapted to live in dessert. It can survive without drinking water. Rodents make underground burrows at the base of shrub or small bush. It spends most of its day sleeping in the burrow underground to avoid intense heat and comes out to feed at night when temperature falls and desert becomes cooler.

Answer:
According to research, the concentration of gold ions in the seawater is 10⁻¹⁴g/cm³.
Answer:
The correct answer is option C.
Explanation:
Heat of formation is defined as change in enthalpy during the formation of 1 mole of compound from its constituent elements in its standard states.it is denoted by symbol . Its units are Kilo joules per mole.
- If <0, the change in enthalpy is negative then it means that energy is released during the formation of 1 mole of substance.
- If >0 , the change in enthalpy is positive then it means that energy is absorbed during the formation of 1 mole of substance.
For example:
286 kilo Joules of energy given out when 1 mole of liquid water is formed.
Answer:
Li⁺
Explanation:
In ion formation, the ionization energy plays a very important role. To form an ion, an atom will lose or gain an electron to become charged.
The higher the ionization energy of an atom, the more the energy required to remove an electron from it to form an ion.
- Ionization energy is the energy required to remove an electron from an atom.
- It is the readiness of an atom to lose an electron. The lower the value, the easier it is for an atom to lose an electron and vice versa.
Generally, down the group, ionization energy decreases. Since both potassium and lithium are in group 1, Li will have a higher ionization energy. It will take more energy to form Li⁺ compared to K⁺.
