A _______ is a segment of a chromosome that codes for a specific protein.

2 answers:

4 0

The correct answer is gene. Genes are carriers of the genetic material that get transferred from a parent to an offspring after sexual reproduction. If the proteins and the codes are synthesized badly, things like genetic disorders are created and these are diseases that get transferred from a parent to a child like Huntington's disease or anything similar.

Eutrophication can cause excess algae growth. Which of the following describes how nutrients contribute to eutrophication?

dusya [7]

Eutrophication of water bodies like lake, pond, shallow stretches of river, etc. is the phenomenon where excess growth of vegetation on the surface of the water takes place. This excess growth results in the clouding of the water, depletion of dissolved oxygen in water, and the death of aquatic organisms. The primary reason for the cause of eutrophication is the presence of nutrients in excess amounts in the water. The nutrients B. come from fertilizer and sewage runoff.

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.

How does an enzyme inhibitor work ?

Georgia [21]

An enzyme inhibitor works as a combination in order to slow down the rate of an enzyme-catalyzed reaction. In order for an enzyme inhibitor to do this, it impacts the of "S" and/or the turn over number. An enzyme inhibitor can also be organic or inorganic and can be found in drugs or antibiotics.
