Answer: True

Abiotic factors are the non-living factors which play important role for sustaining life on earth. These includes water, soil, air and sunlight. Water is important for all the trophic levels of the food chain. Water is the necessary ingredient of the available biomass in all the trophic levels. The large part of the body weight in all the organism consists of water. In the absence of water the organisms may not survive and they will die. If the organisms from the lower trophic levels decline in number then the dependent organisms of the higher trophic level will also decline.

Therefore, the statement Abiotic factors, like water, are critical to most food chains. is true.

On the Galapagos Islands, Darwin observed tortoises with domed and saddle-shaped shells. How did Darwin's observations of these

photoshop1234 [79]

Answer:

The correct answer would be C. The tortoises provided evidence that different species have adaptations suited to their particular environments.

Darwin observed that how different environment on different island lead to the development of different species as a result of adaptations and natural selection.

For example, tortoise inhabiting well-watered islands which used to have short and cropped vegetation had developed a dome-shaped shell.

In contrast, the tortoise inhabiting the arid islands had developed saddle-shaped shells. It is because they needed to stretch their necks in order to reach branches of cactus and other vegetation available in the area.

Consequently, they developed long necks and high peak to the front edges of their shells. It made it possible for them to stretch their heads vertically.

How is enthalpy used to predict whether a reaction is endothermic or exothermic?

Radda [10]

Answer:

$329.48 KJ/mol$ heat is released by the combustion of $2 mol$ of methane

Explanation:

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).

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

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

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

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

$= -787 KJ/mol+1116.48 KJ/mol$

$=329.48 KJ/mol$

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

*What is the relationship between DNA and gene expression? How do they depend on each other?*

Solnce55 [7]

Answer:

Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins? or other molecules, it is called gene expression
