Answer:

c.5

Explanation:

moles= mass/molar mass

molar mass of Ca(OH)2=74.092gmol-1

moles=370.47/74.092

moles =5

Considering the definition of molar mass, 5 moles of Ca(OH)₂ are present in 370.47 grams of Ca(OH)₂.

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.

In this case, you know the molar mass of the elements is:

Ca= 40 g/mole

O= 16 g/mole

H= 1 g/mole

So, the molar mass of the compound Ca(OH)₂ is calculated as:

Ca(OH)₂= 40 g/mole + 2× (16 g/mole 1 g/mole)

Solving:

Ca(OH)₂= 74 g/mole

Next, you can apply the following rule of three: If by definition of molar mass 74 grams of the compound are contained in 1 mole, 370.47 grams of the compound are contained in how many moles?

[tex]amount of moles=\frac{370.47 gramsx1 mole}{74 grams}[/tex]

amount of moles≅ 5 moles

Finally, 5 moles of Ca(OH)₂ are present in 370.47 grams of Ca(OH)₂.

1.) True

The reason this is true is because adjusting the camera allows you to get an understanding of how someone else should look or how they would likely look best when photographed. It also gives an understanding of how a camera should be aimed to get the best result.

2.) True

While many cameras have this feature, most are configured to only use this feature when the photographer selects it. This feature allows the photographer to adjust the camera in case they feel something isn't quite right with it, and it also allows them to get into the picture themselves if they feel they want to.

Hope this helps you, and have fun with whatever it is you are doing with your camera.

Explanation:

Answer: Depends on the balance between blood pressure and osmotic pressure.

Explanation:

The capillaries are part of the microcirculation that transports nutrients to the tissues and removes cell excreta. The walls of the capillaries are extremely thin, constructed of single - layer, highly permeable endothelial cells. Therefore, water, cell nutrients and cell excreta can all interchange quickly and easily between the tissues and the circulating blood.

The tissues of the body is made up of soo many capillaries which helps to deliver blood and it's contents to it. The hydrostatic pressure in the capillaries tends to force fluid and it's dissolved substances through the capillary pores into the interstitial spaces. Conversely, osmotic pressure caused by the plasma proteins( called COLLOID OSMOTIC PRESSURE) tends to cause fluid movement by osmosis from the interstitial spaces into the blood. This osmotic pressure excreted by the plasma proteins normally prevents significant loss of fluid volume from the blood into the interstitial spaces.

Therefore, a balance between hydrostatic pressure in the capillaries which is influenced by blood pressure and osmotic pressure in order for a net flow of fluid into or out of a capillary to occur.

A pulse of sugars labelled with a fluorescent dye is supplied to leaves of young plants. After a brief interval, tissue sections are obtained from the plant and examined under the fluorescence microscope. Tissues are scored for the presence of fluorescence and ranked from very high to low fluorescence. Which cells would contain the most fluorescence

a. xylem

b. companion cells

c. sieve elements

d. epidermis

Answer: b. companion cells

Explanation:

The xylem and phloem are the vascular tissues in plants. Their function is to transport water and sugars respectively to all the parts of the plant body. Xylem is only involved in water transport. Companion cells and sieve elements are the two components of the phloem. The companion cells are the storage house of sugars they have a role in movement of the sugars in and out of the sieve elements. They take up sugars via active transport by using their transmembrane proteins. The companion cells will show major fluorescence as these are the reservoir of sugars.

Answer:

The Hawaiian honeycreeper bird population will decrease because they rely on the Hawaiian silversword plants for survival.

Explanation:

The destruction of Hawaiian silversword plants due to human development hurts the Hawaiian honeycreeper bird population as the bird exists in a mutual relationship with the plants.

Hawaiian honeycreeper bird has a mutual relationship with Hawaiian silversword plants, where the bird feeds on the plant's nectar and pollinates the flowers. If the plant population decreases, it will result in a reduced food supply for the bird which decreases their population size.

Loss of the silversword plants also destroys their habitat which can impact their population. Therefore, human development results in a decrease in the Hawaiian honeycreeper bird population.

However, the loss of the honeycreeper bird population also affects the ecosystem as they play a very important role in seed dispersal and plant reproduction which reduces plant diversity and also negatively impact other species that depend on the Hawaiian silversword plants for food.

Therefore, the destruction of Hawaiian silversword plants hurts the Hawaiian honeycreeper bird population as the bird exists in a mutual relationship with the plants.

Explanation:Coastal wetlands in the southeastern U.S. provide many important ecosystem goods and services. In addition to supporting important fish and wildlife habitat, they maintain coastal fisheries, store carbon, improve water quality, protect coastlines, and provide recreational opportunities. In many ways, coastal wetlands are dynamic and resilient ecosystems; however, they are being subjected to tremendous environmental change at the regional (e.g., hydrologic alterations, nutrient enrichment) and global scale (e.g., climate change).

One aspect of global change that is expected to have a substantial impact on coastal wetlands is winter climate change. Salt marshes and mangrove forests are common coastal wetland ecosystem types that occupy similar estuarine environments but have different climatic tolerances. In warmer climates, mangrove trees often outcompete salt marsh grasses. However, mangrove forests are sensitive to freezing temperatures, and within the region, mangrove forests are currently found only in Florida, Louisiana, and Texas (though isolated individuals have been reported in Mississippi). Salt marshes are more dominant along colder coastlines where mangroves are not able to survive freeze events. Future climate change is expected to result in increased winter temperatures and, potentially, reductions in the intensity of freeze events which could lead to mangrove forest replacement of salt marsh in parts of the Gulf of Mexico and southeastern Atlantic coast.

From a functional perspective, salt marsh grasses and mangrove trees are foundation species that control ecosystem dynamics and, in stressful and highly dynamic environments, provide the structural properties needed by other species; hence, the ecological and conservation implications of grass-to-tree conversions in coastal wetlands could be large (in both positive and negative ways). Dr. Mike Osland, USGS Research Ecologist and GCPO LCC staffer, along with 4 collaborating scientists, has initiated a study that addresses the following question: how might winter climate change impact the distribution and abundance of salt marshes and mangrove forests in the southeastern U.S.?

Their results begin to illustrate the vulnerability of salt marshes in the southeastern U.S. to mangrove forest expansion and quantify the amount of salt marsh habitat within each state that could be impacted by mangrove forest expansion under various winter climate change scenarios. The preliminary results are striking in terms of the potential for mangrove forest range expansion and coastal marsh displacement in the region. The hope is that these analyses stimulate additional discussion, research, and planning regarding the potential ecological and conservation implications of winter climate change for coastal wetlands in the southeastern U.S.

Answer:

Salt marshes are coastal wetlands found throughout the world on protected shorelines and on the edges of estuaries where freshwater mixes with seawater.

Mangrove forests are those which contain Mangroves which are trees and shrubs that grow in saline (brackish) coastal habitats in the tropics and subtropics.

Answer:

Answer: Climate change will likely increase the frequency and strength of extreme events (such as floods, droughts, and storms) that threaten human health and safety. Climate changes may expose more people to diseases. Some groups of people (e.g., the very young and the very old) are especially vulnerable to health impacts. First, older people are physically more vulnerable to extreme heat, so population aging could exacerbate increases in heat-stress mortality brought on by climate change. Higher temperatures also exacerbate outdoor air pollution such as ozone, which also disproportionately affects older people. Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats. Climate affects population distribution both directly as well as indirectly through its effects on soil, vegetation and agriculture that have direct bearings on the pattern of population distribution. ... This explains a high density in the tropics, which are otherwise marked with extremes of climatic conditions.

Explanation:

Answer:

Glucose present as monomers within the cell will exert more osmotic pressure than a single glycogen molecule, resulting in endosmosis and the lysing of cells.

Also, the presence of free glucose molecules will result in increase in weight of the liver due to lack of efficient packing as in glycogen as well as the association ofnthe glucose molecules with water molecules.

Explanation:

Glycogen is a polysaccharide composed of glucose monomer units linked to Each other by α-1,4-glycosidic binds. α-1,6-branches arises at about every 10th glucose residue in the straight chain. Thus animals more glucose molecules to be stored within a much smaller space, thereby incresing the bulkiness of glycogen. Glycogen molecules are insoluble in the aqueous medium of the cell because it doesn't have enough free polar groups to participate in hydrogen bonding with water and are stored as granules and therefore do not affect the water potential or osmotic balance of the cell.

On the other hand, glucose molecules are highly soluble in water because it has many free polar -OH grours that form hydrogen bonds with water. If the glucosyl residues in large numbers of glycogen molecules were replaced with an equivalent number of molecules of free glucose, the free glucose will exert a high osmotic pressure inside the cell, causing the entry of water in the cell by endosmosis resulting in swelling and lysis ofnthe cell. Also, the space occupied by these free glucose units within the cell will be much larger than that of glycogen whichmenables efficient packing ofthe glucose molecules.

A. 3.9% people in the population would be expected to be heterozygous carriers

Explanation:

The genotype frequency for the CF affected is 1/2,500,

= 1/2500

= 0.004. This is equal to q^2

here q = frequency of recessive alleles combination or CF people. (H-W equation => p^2+q^2+2pq=1)

The allele frequency is the square root of q^2 value, which equals 0.02. The frequency of the dominant allele or p would be

1 - 0.02 = 0.98 (p+q = 1)

The frequency for the CF combinantion =0.004

the dominant or unaffected people genotype

= (098)^2

= 0.96;

and for the heterozygote, it is

= 2pq

=2(0.98)(0.02)

= 0.039 or 3.9%
