Which of these buildings is most likely to have indoor air pollution

2 answers:

<span>The building from the list provided with the highest likelihood of air pollution is a tightly sealed house with an unvented water heater. The school with leaks will let air exchange happen so that isn't it, and having a carbon monoxide detector only reports existing air pollution it doesn't prevent air pollution, it could have issues but we don't know. The tightly sealed house with the unvented water heater is a near sure thing.</span>

when heater is on for long time without having ventilation then carbondioxide will be converted into carbon monoxide and causes air pollution.

So according to above explanation,

C. A tightly sealed house with an unvented water heater, is the correct answer.

Which of the following would most likely be found in the sands at Myrtle Beach?

sergejj [24]

The correct answer is option A, that is, placer deposits.

The concentration of heavy deposits known as the placer deposits are produced by the gravitational action, generally found in streams. The minerals that take place as placer deposits comprise copper, gold, magnetite, cassiterite, and copper.

The formation of placer deposits takes place when the metal-bearing rock on land is weathered and the generated debris is washed down to the sea by the rivers. Further by the action of waves, currents, and rides the particles of heavy metal gets amassed to produce mineral sand deposits. These generally occur as beach deposits.

In the above diagram of a plant cell, what is the function of structure 3?

kramer

Explanation:

B. serves as the control center of the cell and contains the cell's genetic information

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wounucleuscarbohynd around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Further Explanation:

A cell's structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins

<h2>Cell Cycle </h2>

Explanation:

Eukaryotes grow and divide by cell cycle.

The main parts of a cell cycle are an ordered series of events – Gap 1 or G1 phase, Synthesis or S phase, Gap 2 or G2 phase, and the mitosis or M phases.

Interphase period (G1, S, G2 phases) - cell grows by size, duplicates its content, replicates its DNA, and finally prepares for mitotic cell division .

Mitosis and cytokinesis - formation of two identical daughter cells

Cell cycle is regulated by regulatory or restrictive checkpoints in the cell cycle which are activated with detection of a defective DNA.

Proliferation of undesired or cells with defective DNA like in case of tumor cells is controlled by the action of suppressing agents like p53 and cyclins.

The tumor suppressor gene protein p53 prohibits division of tumor cells. Cyclins regulate cell cycle by activation of the enzyme cyclin-dependent kinase.
