I will copy and paste a paragraph from the site

During the COVID-19 pandemic we witness the increased use of rapid executive decisions by governments, based on scientific advice. What role does that leave for citizens participation? An important one. Because good policy solutions depend on scientific expertise and the lived reality of citizens.

Citizens’ perceptions and concerns are by definition biased, but they represent a reality which is at least as important as the scenarios perceived by scientists. Based on that, I would like to highlight three arguments in particular that underline the importance of active and effective citizens’ participation in the times of Corona.

I really hope this helps!

Public participation is important in a democratic society during the pandemic for several reasons, such as responsiveness and transparency. Public participation in decision-making during the pandemic is important for transparency, accountability, responsiveness, etc.

Public participation is crucial for ensuring transparency in the decision-making process during the pandemic. When citizens are involved in the decision-making process, they are better informed about the policies and procedures being implemented to manage the pandemic. This creates a sense of accountability on the part of the government, which is important for maintaining public trust and confidence. Public participation also ensures that the policies and procedures being implemented are responsive to the needs and concerns of the public. When citizens are actively involved in the decision-making process, they are better able to communicate their needs and concerns to the government.

Hence,  Public participation is important in a democratic society during the pandemic for several reasons, such as responsiveness and transparency.

The reinforced, threadlike pseudopods that radiate from the cell as depicted in these illustrations of radiolarians are generally characteristic of the group of organisms known as Rhizarians.

Rhizarians are a diverse group of single-celled eukaryotes that are characterized by their threadlike pseudopods, which they use for locomotion and feeding.

Mostly unicellular eukaryotes make up the ill-defined yet species-rich subgroup known as the Rhizaria. They are all non-photosynthethic, with the exception of the Chlorarachniophytes and three species of the genus Paulinella in the phylum Cercozoa, but many foraminifera and radiolaria have a symbiotic connection with unicellular algae.

These pseudopods are reinforced by microtubules, which give them their characteristic appearance.

Radiolarians are one of the most well-known groups of Rhizarians, and are distinguished by their intricate and beautiful silica skeletons.

Two resources that bacteria will need to complete for as the population grows are : C. Space  D. Food

Bacteria are ubiquitous, free-living organisms and often consisting of one biological cell.

The bacteria will need food and space as the population grows larger. While light and oxygen may be important for some types of bacteria, the question specifies that bacteria are growing on a gel that provides nutrients, so it's safe to assume that they already have access to the necessary nutrients.

As the population of bacteria grows, they will need more space to spread out and access to more food to sustain their increased metabolism and growth. Oxygen may also become a limiting factor if population becomes too dense and uses up the available oxygen in Petri dish.

The stress in spring with Young's modulus is equivalent to 300 Pascals, given that its deformation is 30. The stress in the spring is 9000 Pascals.

Firstly, it's important to note that stress and deformation are related to each other through Hooke's law, which states that stress is proportional to deformation for a linearly elastic material like a spring.

Mathematically, this can be represented as:

Stress = Young's modulus × Deformation

Substituting the given values into the equation, we get:

Stress = 300 Pa × 30

Stress = 9000 Pa

It's important to note that stress is a measure of force per unit area, so it's important to specify the cross-sectional area of the spring to fully define the stress. Additionally, the units of stress can vary depending on the system of units used, but in this case, Pascals are used, which are the SI units of stress.

The expected maintenance rate prescribed by the HCP fοr the intravenοus fluid fοr Henry wοuld be apprοximately 62.5 ml/hοur.

Tο calculate the expected maintenance rate fοr Henry, we can use the Hοlliday-Segar methοd, which recοmmends a maintenance fluid rate οf 100 ml/kg/day fοr the first 10 kg οf bοdy weight, plus 50 ml/kg/day fοr the next 10 kg οf bοdy weight, plus 20 ml/kg/day fοr any additiοnal bοdy weight.

Based οn Henry's weight οf 4000 gm (which is 4 kg), his expected maintenance fluid rate wοuld be:

100 ml/kg/day x 10 kg = 1000 ml/day fοr the first 10 kg οf bοdy weight

50 ml/kg/day x 10 kg = 500 ml/day fοr the next 10 kg οf bοdy weight

20 ml/kg/day x (4 kg - 20 kg) = 0 ml/day fοr any additiοnal bοdy weight

Sο, the expected maintenance fluid rate fοr Henry wοuld be:

1000 ml/day + 500 ml/day = 1500 ml/day

Tο cοnvert this tο an hοurly rate, we can divide by 24 (the number οf hοurs in a day):

1500 ml/day ÷ 24 hοurs/day ≈ 62.5 ml/hοur

Therefοre, the expected maintenance rate prescribed by the HCP fοr the intravenοus fluid fοr Henry wοuld be apprοximately 62.5 ml/hοur.

In contrast to aerobic and anaerobic cellular respiration, the ending molecule (byproduct) of fermentation is organic.

Fermentation is the anaerobic respiration in which a carbohydrate molecule is broken down into smaller molecules such as organic acid or alcohol and releases energy.

The two types of fermentation are alcoholic fermentation and lactic acid fermentation. Alcohol fermentation, carried out by yeast, produces ethanol and carbon dioxide as byproducts, while lactic acid fermentation, carried out by some bacteria and muscle cells, produces lactic acid as a byproduct.

An example of alcoholic fermentation is the production of ethanol from glucose, and an example of lactic acid fermentation is the production of lactic acid from pyruvate.

Thus, the ending molecule (byproduct) of fermentation is organic. The byproducts of fermentation include organic compounds such as ethanol, lactic acid, and carbon dioxide. Therefore, it's an organic byproduct.

The cells that form a protective barrier to the vascular system of a root and prevent water from leaking out under pressure from the stele are the endodermis cells.

The endodermis cells form a continuous cylinder around the root, known as the endodermic cylinder, through which all materials must pass before reaching the stele. This cylinder is composed of a thick band of tightly packed cells with a waxy cuticle, which prevents water from passing through and maintains pressure in the stele.

The epidermal cells of a root form a protective barrier to the vascular system, where all materials must move through the symplast and prevent water from leaking out under pressure from the stele.

In botany, symplast is a continuum of living plant tissues consisting of the cytoplasm of living cells and the plasmodesmata that interconnect them. This means that the symplast is the living component of the plant, with every living cell containing a part of it that is contiguous with other living cells, forming a continuous cytoplasmic space that extends through the entire plant.

It should be noted that water can be lost through the cuticle and cell wall of root hairs, which is not related to the stele. To prevent water from being lost, the root endodermis, a single layer of cells enclosing the vascular tissue, can be selectively permeable to water, causing it to move into the xylem via the apoplast rather than the symplast, where it can be transported up the plant.

The four main families of biochemicals (macromolecules) are nucleic acids, proteins, carbohydrates, and lipids.

Nucleic acids, such as DNA and RNA, are composed of nucleotides, which are made up of a phosphate group, a sugar (deoxyribose or ribose, respectively), and a nitrogenous base. DNA is composed of four nitrogenous bases (adenine, thymine, cytosine, and guanine) while RNA has adenine, thymine, cytosine, and uracil.

Proteins are composed of amino acids and form the four levels of structure: primary (linear sequence of amino acids), secondary (alpha helix or beta pleated sheet), tertiary (3D folding of the polypeptide chain), and quaternary (more than one polypeptide chain).

Carbohydrates are composed of monosaccharides (simple sugars like glucose), disaccharides (double sugars like sucrose), polysaccharides (many sugars like starch or glycogen), and polyalcohols (like glycerol).

Lipids are composed of fatty acids, alcohols, and carboxyl groups. Fatty acids are chains of hydrocarbons with a carboxyl group at one end, while alcohols have a hydroxyl group at the end. Phospholipids, which form cellular membranes, are made of two fatty acids, a phosphate group, and a hydrophilic head group.

Waxes are also lipids, composed of long chains of fatty acids with an alcohol attached to one end. Cholesterol is a lipid composed of four fused hydrocarbon rings with hydroxyl and methyl groups attached.

A forest found in a broad belt in Northern Eurasia and North America, where conifers predominate is called the Taiga.

The term “Taiga” comes from the Russian word for forest or woodland. It is the largest terrestrial biome on earth, covering approximately 17 million square kilometers, or 11% of the earth's land area. It is primarily found in high latitudes, just south of the Arctic tundra.

Taiga Forests are located across northern Russia, Mongolia, Scandinavia, Alaska, and Canada. There are distinct seasons in the Taiga, with long, cold winters and short summers. Due to the region's high latitude and the tilt of the earth, the sun's rays are scattered, leading to long periods of darkness during the winter.

The summer is brief and characterized by 24 hours of daylight in some locations. The Taiga is a region of coniferous trees, including spruce, pine, and fir trees. These trees have adapted to the harsh environment, with their needles remaining green all year to capture sunlight during the brief summer months.

The Taiga is also home to a variety of mammals, including bears, wolves, lynx, and moose. In the winter, some animals hibernate, while others migrate to warmer regions.

At this time it became the general view that viruses were biologically "alive." This changed in 1935 when the tobacco mosaic virus was crystallized and scientists demonstrated that the particles lacked any mechanisms necessary for metabolic function.  It was determined that viruses consisted of a nucleic acid, DNA or RNA, surrounded by a protein shell and the scientific view changed: viruses are complex biochemical mechanisms but not alive. When not in contact with a host, the virus remains dormant. During this time there are no biological activities occurring and the virus is nothing more than a static organic particle. In this state viruses can remain for extended periods of time, waiting to come into contact with the appropriate host. When in contact with a host, it becomes active, reacts to its environment and/or host and directs its efforts toward self-replication. The viral goal now is to produce more viruses to attack host cells.
