Answer: Mobile Sources, Stationary Sources, and Area sources

In my own words.

Explanation:

Mobile sources such as cars and vehicles that run on oil release carbon monoxide which pollutes the air.

Stationary sources such as factories burn fossil fuels and release green-house gasses.

Area sources such as lumber and fire-wood places burn wood and release harmful gasses in the air.

zloy xaker [14]

Answer:

Lipid intake through diet is important for the infants as it helps in growth, development.Brain, retina and nerve tissues contain long chain PUFA(Poly unsaturated fatty acid) that is provided through the intake of lipids.

Explanation:

Dietary lipid is traditionally be consider as an important and essential nutrient for the infants as they provide many function in the body of infants They helps for proper growth and development of the infant.Thus selection of dietary lipid is important.Brain, and other neural tissue contain long chain poly unsaturated fatty acid that are important for producing eicosanoid. They are powerful mediators as they helps in different functions that are performed by cells and tissues.More over fat provide energy that are required for doing various physiological activities.

The graph below shows the radioactive decay of a material whose half life is 25 years.
yawa3891 [41]
The half life is the time taken for the amount of a substance to become half of its original value. If we take the initial value to be 30 on the y-axis, the half of 30 is 15. We check the time at which the substance has reduced to 15 atoms and this is about 40 seconds. <span>40 seconds therefore, is your answer.</span>

The protein thorain is encoded by the gene thrL, and thorain is a negative regulator of the thrMN operon. Assume there is no oth
KIM [24]

Answer:

The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.

Explanation:

Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.  

With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.
