3 0

Answer:

The correct answer would be calcium ion and cAMP.

Secondary messengers refers to the intracellular signaling molecules which pass the signals from the receptors located on the surface of the cell to the target molecule present within the cell.

The secondary messengers can be classified into three major class:

  1. Cyclic nucleotide for example cAMP (cyclic adenosine monophosphate), cGMP (cyclic guanosine monophosphate)
  2. DAG (diacylglycerol) and IP₃ (inositol triphosphate)
  3. Calcium ions (Ca⁺⁺)  

Hence, from the given options, calcium ion and cAMP would make the correct choice.

The organs represented in the image are the Brain, nerve, and spinal cords that monitor and react to changes in the body and its environment.

<h3>What are Organs?</h3>

Organs may be defined as an assemblage of tissues that structurally construct an operational unit specialized to accomplish a distinct operation and functions in the body of a living organism.

The nerves function in sending and receiving signals to the brain from external stimuli. They give the perception of feeling pain, relaxation, stress, etc to the brain according to the situations.

The complete question is as follows:

The picture shows an organ system in the human body.

Brain, Nerve, and spinal cord.

What do these organs do in the human body?

  • They filter pathogens and dead cells out of lymph before it returns to the blood.
  • They monitor and react to changes in the body and its environment.
  • They release hormones that control the activities of cells and organs.
  • They identify and destroy things that are foreign or harmful to the body.

Therefore, the correct option for this question is B, i.e. They monitor and react to changes in the body and its environment.

The first place that the reabsorption of water is not automatically coupled to the reabsorption of filtered solutes occurs in th
Alina [70]

Answer:

False

Explanation:

The correct answer is false because Reabsorption of water and other filtered solutes like vitamins, sodium e.t.c. take place in the proximal convoluted tubules.

Reabsorption is when water and solutes in the PCT are removed and moved back into the blood and it's a process that take place through bulk transport.

The solutes and water are transported from the PCT to the interstitium and then move into peri-tubular capillaries and reabsorption in PCT is isosmotic i.e solutes have the same osmotic pressure.

In a power house, energy is usually produced for use.

The mitochondrion is tagged the powerhouse simply because energy for use in the body is produced in this cell organelle.

  • The metabolic processes that releases energy from food materials occur in the mitochondrion.
  • The kreb cycle takes place in the mitochondrion.
  • Cellular respiration in which energy is liberated from food materials occur here.
  • Without the mitochondrion, the body will not be able to have energy to perform its life functions.
