Answer:

c) Decreased land availability for growing food to feed the growing population.

Explanation:

  • Growth of population demands increased use of resources.
  • As the population grows more and more settlements and industries are built .
  • Clear lands are taken up by companies and builders to build factories , roads and settlements.
  • As a result the availability of agriculture decreases to a great extent.
  • Hence land for growing food crops also falls short.
  • Lower food production ultimately leads to a hunger stricken population.
  • Thus , decreased land availability for growing food feed the growing human population  is a direct impact of growing population.

Explain how thing that plants or animals do are done by the work of cells.
ipn [44]
<span>Basically because of the presence of cellular organization and hierarchy which organs are influenced by individual autonomic cells.

The cellular organization relates with one another since the colossal cell, the organ system is fundamentally composed of cells. Cells are the building blocks of these structures and which creates such organ and organ system. They associate as one cell intercommunicates with another cell until all received the message and translates it and sends it with another organ and to cell -vice-versa. And also, they become interdependent with the other cell -other tissue -other organs -other organ system. </span>
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole. Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis.This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. How? Through cell division called, mitosis. Excerptmeiosis –cell division specifically in the sex cells.<span> </span>

GuDViN [60]
Wow! this si a huge question but analyzing all the datils from ths option you give me I have to say that C option: <span>Heat energy became trapped in the atmosphere by greenhouse gases and was used as an energy source in the building of macromolecules, is the one that gets closer to what the scientists have said recently. Take into account for example, the examinations of Dr. Stanley Millers. I think this can help you</span>

Nonvascular plants have a system that transports water and nutrients throughout the plant’s body
solniwko [45]

Answer:

False

Explanation:

Plants, based on whether they can conduct water and nutrients, are classified into vascular and non-vascular plants. Vascular plants also called TRACHEOPHYTES are plants that possess certain special tissues called vascular tissues used for conducting water and nutrients in a plant. These conducting tissues are xylem and phloem.

On the other hand, non-vascular plants do not possess vascular or conducting tissues, hence, they cannot transport water and nutrients throughout the plant. Hence, such plants are naturally found in moist areas e.g. mosses. Therefore, based on the question asked, the answer is FALSE.

How is enthalpy used to predict whether a reaction is endothermic or exothermic?
Radda [10]

<u>Answer:</u>

<em>329.48 KJ/mol heat is released by the combustion of 2 molof methane</em>

<u>Explanation:</u>

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)

\Delta H \ reaction=[ 2(\Delta HfCO_2)+ 4(\Delta HfH_2O)]-[2(\Delta HfCH_4)+4(\Delta HfO_2)]

                            =2 ( -(393.5 KJ)/mol)-[2( -74.6 KJ/mol)+4(-241.82 KJ/mol)]

                            = -787 KJ/mol-[ -149.2 KJ/mol-967.28 KJ/mol]

                           = -787 KJ/mol+1116.48 KJ/mol

                                          =329.48 KJ/mol

<em>In this question, </em><em>the enthalpy of formation</em><em> has positive value and hence the </em><em>reaction is endothermic</em><em> in which the heat is released. </em>
