What determines whether a particular cell is able to respond to a hormone? What determines whether a particular cell is able to
Zielflug [23.3K]

Answer:

<u><em>The correct option is the presence of a specific hormone receptor.</em></u>

Explanation:

Every cell membrane contains certain cell surface receptors which detect an extracellular molecule and allow it to perform function inside that particular cell. The cell surface receptors receive and transmit signals.

For a specific hormone to function inside a particular cell, the cell must possess a specific hormone receptor embedded in the plasma membrane which will detect the hormone and allow it to function inside the cell.

The statement, "All living organisms can reproduce, and parents pass on biological information to offspring," best describes whi
ehidna [41]

Answer:

A. inheritance and reproduction

Explanation:

These two terms are interrelated as the act of one (reproduction) gives rise to the other (inheritance). The process whereby offsprings are produced using gametes (sexual reproduction) or without gametes (asexual reproduction) from a an organism called the parent is called REPRODUCTION. Reproduction is necessary to ensure the survival of a particular species.

During reproduction, the genetic material (DNA) in form of chromosomes of an organism is passed down from parents to offsprings in a process called INHERITANCE or HEREDITY. The information needed for certain processes like growth, reproduction, survival and others are contained in the genetic material, and are transferred from the parents to their progenies.

In sexual reproduction, this biological information encoded in the genetic material is passed on via gametes produced by each parent (male and female) during meiosis.

A hairdryer uses 1500 J of electrical energy in 1 second. The hairdryer changes 1300 J of this to useful thermal energy in 1 sec
Katarina [22]

200 J of energy is wasted by the hair dryer.

Steps

  • The hairdryer is provided with 1500 J of electrical energy per second
  • Of this 1500 J, 1300 J of energy is actually used and converted to useful thermal energy per second
  • The remaining energy, 1500 - 1300 = 200 J is dissipated

Dissipated energy

  • The energy that is not efficiently transported or changed is wasted energy.
  • We cannot create or destroy energy.
  • An employable type of energy is created through transformation.
  • Only a portion of energy that is changed or transferred can be done so in a way that is helpful.

Thus, 200 J of energy is wasted by the hair dryer.
