Afamily's apartment lease has expired, but their landlord has indicated to them that they may remain on the premises until a sale of the building is closed. they will be charged their normal monthly rental during this period. the right held by the family is called a(n) ) tenancy at will. b) estate at sufferance. c) year to year holdover. d) estate for term.

The correct answer is A) tenancy at will.

Explanation:

Tenure at will, also known as equity at will, is a property tenure - without a lease or written agreement - that can be terminated at any time by either the tenant or the owner (owner). It exists without a lease or contract and usually does not specify the duration of a tenant's duration or the exchange of payment. A lease arrangement at will is desirable for tenants and landlords who wish to have the flexibility to change rental situations easily and without breaking a contract.

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
