Answer:

Option A , natural resources and human labor

Explanation:

These days there is heated conversation everywhere regarding the sustainable development but when it comes to accountability of naturally available resources, most of the nations do not have any indices to measure the  consumption rate of natural resources or the left out resources.

Human population however is not even considered a resource in most of the nation and thus its accountability is questionable in all the nations.  

Hence, option A is correct

What do having the measles and being vaccinated against the measles have in common?
photoshop1234 [79]

They are both forms of active immunity.

<h3>What is active immunity?</h3>

When our own immune system defends us against a pathogen, this is known as active immunity. Our immune system develops active immunity when exposed to a potential disease-causing substance (i.e., pathogen). Active immunity is crucial since it not only "fights off" these pathogens but also lasts a very long period in the form of immunologic memory.

B and T lymphocytes with the ability to recognize a particular pathogen make up immunologic memory. These cells circulate at low levels in human bodies, but if they become "activated" by encountering the pathogen while traveling, they rapidly begin to multiply and send signals to other immune system components to do the same. There are two reasons memory cells are important. They first help our immune systems react swiftly. The immune response is prepared the moment the infection is contacted since they are secondly pathogen-specific.

I understand the question you are looking for is this:

What do "having the measles" and being vaccinated against the measles have in common?

  1. They are both forms of active immunity.
  2. They are both forms of neutral immunity.
  3. They are both forms of passive immunity.
  4. They are both forms of infection.
  5. They are both forms of immune deficiency.

Which statement best describes two paths carbon dioxide can take through the carbon cycle? Carbon cycle ends when carbon dioxide
tankabanditka [31]

Carbon dioxide plays an important role in carbon cycle. Carbon dioxide is used by plants in the process of photosynthesis to make food. The food is eaten by animals to gain energy and performs cellular respiration which releases carbon dioxide back to the atmosphere. This is the process of biological carbon cycle.

In geological carbon cycle, carbon dioxide enters the ocean by precipitation and combines with elements like calcium forming a compound and becomes the component of living organisms. Carbon compounds settles in the ocean when the organisms die.
