<h3><u>Answer;</u></h3>

TGA ATA CCT

<h3><u>Explanation;</u></h3>
  • DNA is a nucleic acid that stores all the genetic information of an organism.
  • <em><u>DNA is a double stranded molecule and contains the nucleotide bases, Adenine, Guanine, Thymine, and Cytosine.</u></em>
  • <em><u>The DNA strand and its complementary strand are held together by hydrogen bonds between the base pairs on both stands. Guanine base on one strand is bonded to Cytosine base on the opposite strand. Adenine bonds or pairs with Thymine base on opposite  strand.</u></em>

Nonrenewable resources are used much more prevalently today despite knowing that they pollute and will run out in the future. wh
KIM [24]

We are not using more renewable resources because we have been using fossil fuels since the 18th century and renewable resources are comparatively new. Also, we have limited knowledge about them, so it will take time to change our mindset toward renewable resources.

Based on exhaustibility, there are mainly two types of resources, renewable resources, and non-renewable resources.

Renewable resources are those resources that are replenished while non-renewable resources are those resources that are not replenished.

The non-renewable resources take millions of years to form and once exhausted they cannot be made more.

Examples of renewable resources are solar energy, wind energy, geothermal energy, etc. while examples of non-renewable resources are fossil fuels like coal and petroleum, metals, etc.

Despite the fact that the supply of non-renewable resources like coal and petroleum is limited and they also cause pollution, the use of them is rampant around the world.

The use of fossil fuels is widespread because we have been using them since the 18th century and the use of renewable resources is a very recent phenomenon.

Also, a major hurdle for using renewable resources is the upgrading of current technology to harness these resources.

The newer technologies are generally more expensive to employ, for example, the solar cells used for storing solar energy are made up of elements like silicon, silver, and gallium which are expensive.

Unattached microbes are moved from the lungs to the epiglottis by the _______ effect.
lisov135 [29]

Answer:

The unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>

Explanation:

Mucociliary escalator, also known as mucociliary clearance, is one of the major defense mechanisms that protects the lungs. It describes the self-cleaning mechanism of the bronchi which are present in the lungs. The effectiveness of this mechanism depends on the properties of the produced mucus and on the quality and number of the cilia present in the lining of the airway.

Therefore, the unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
