Charged particles

Neutrons

Protons

Electrons

Answers

Answer:

The answer is Neutrons

An isotope of oxygen with an atomic mass of 18 would have two extra Neutrons. Hence, option B is correct.

What is an isotope?

Isotopes are atoms with the same atomic number but different atomic masses. In other words, atoms having the same number of protons but different numbers of neutrons are called isotopes. Although isotopes have highly similar nuclear properties, they have equivalent chemical properties.

For instance, hydrogen has three isotopes. While tritium (one proton and two neutrons) is radioactive, the other two isotopes are unstable. Stable isotopes exist for most elements. For several elements, radioactive isotopes can also be produced. When compared to lighter isotopes of the same element, heavier isotopes often react more slowly.

An isotope has a different number of neutrons. Therefore, option B is correct.

Explanation:

Spartina is a group of grasses that dominates communities of salt marshes in many coastal areas. Many of the insects, snails, birds, mice, and other animals found in these communities rely on Spartina for food, nest building materials, protection for their young, etc. The roots of Spartina also form dense mats that hold together soil in these ecosystems. Many species that live in Spartina salt marshes cannot survive outside of these unique ecosystems. Because living near the ocean is desirable to many humans, many Spartina marshes have been drained & cleared for human development. Analysis of the destruction that came when Hurricane Katrina hit Louisiana in 2005, however, showed that the reduction of salt marshes in coastal Louisiana was a contributing factor to the storm surge penetrating further inland.
1. The value of Spartina salt marshes in protecting coastal areas from storm surge would be classified as which type?
A. Extrinsic.
B. Intrinsic.
C. Neither.
2. The value of Spartina salt marshes in holding soil together would be classified as which type?
A. Extrinsic.
B. Intrinsic.
C. Neither.
3. In general, you would expect species that only live in Spartina salt marshes to have a higher extinction risk than species that can survive in urban areas.
A. True
B. False
4. Based only on the information included in this scenario, extinction risk for species that only live in Spartina salt marshes would be most influenced by which factor?
A. Restricted geographic range.
B. Narrow habitat requirements.
C. Small population size.

Answers

Answer:

1)a. Extrinsic

2) b. Intrinsic

3) a. True

4) a. Restricted geographic range

Explanation:

1. Spartina Salt marshes are important to the coastal areas as they protect them from storm surge as affecting the erosion of salt marsh edges and it is classified as extrinsic.

2) b. Intrinsic

Intrinsic factors such as vegetation and soil affect the erosion of salt marsh edges.   It is determined by characteristics of soil and root biomass found under the ground.

3) a. True

Species that could survive in urban areas are less prone to extinction than the species that only survive in spartina salt marshes.

4) a. Restricted geographic range

A restricted geographic range is a factor that leads and affects the extinction in endemic species more.

C. Households exchange money for products in resource markets.
D. Household expenditures flow to the product market in exchange

Answers

The statement best summarizes the role of households in the flow of goods is households exchange money for products in resource markets. Thus, option C is correct.

Who are the consumers among households?

The final consumers of the goods and services produced by the businesses are the households. According to their tastes and preferences, they create demand in the market. The businesses supplied and produced goods in response to customer demand. As a result, a nation's production line is determined by its households.

To run a business, workers are needed, and business owners, managers, and employees also have families. In return for labor, the business pays wages, which increase household income.

Therefore, A company's output may fall somewhere in the middle of these two ideas. A landscaping company, for instance, might offer a homeowner a service and sell them a tree as a product.

If two heterozyotes for dwarfism have children what proportion of their kids would you expect to be of typical size and not exhibit dwarfism?

Answers

Answer:

3/4 or 75%

Explanation:

This question involves a gene coding for height in humans. The allele for normal height (D) is dominant to the allele for dwarfism (d).

If two heterozygotes for dwarfism are crossed i.e. Dd × Dd, the following gamete will be produced by each heterozygote parent:

Dd - D and d

Using these gametes in a punnet square (see attached image), the genotypes of the expected offsprings will be as follows- DD (1) : Dd (2) : dd (1)

(1) DD - typical normal size

(2) Dd - heterozygous normal size

(1) dd - dwarf

The offsprings expected to be of typical size and not exhibit dwarfism are offsprings DD and Dd, which represent 3/4 of the offsprings. Hence, the proportion is 3/4 or 3/4 × 100 = 75%.

Compare characteristics of severe weather conditions for thunderstorms tornadoes hurricanes and cyclones

Answers

Explanation:

Thunderstorms:

A thunderstorm is produced by a cumulonimbus cloud, or thunderhead, that includes rain showers, lightning, and thunder.

They start when the sun heats the earth's surface and warms the layer of air above it. This warmed air rises and transfers heat to the upper levels of the atmosphere. As the air travels upward, it cools and the water vapor contained within it condenses to form liquid cloud droplets. As air continually travels aloft in this way, the cloud grows upward in the atmosphere, eventually reaching altitudes where the temperature is below freezing. Some of the cloud droplets freeze into ice particles, while others remain "supercooled." When these collide, they pick up electric charges from one another; when enough of those collisions happen, the big buildup of charge discharges, creating lightning.Thunderstorms are most hazardous when rain decreases visibility, hail falls, lightning strikes or tornadoes develop.

Tornadoes:

tornado is a violently rotating column of air that extends down from the base of a thunderstorm to the ground.

When wind near the earth's surface blows at one speed and wind above that blows at a much faster speed, the air between them whips around into a horizontal rotating column. If this column gets caught in the thunderstorm updraft, its winds tighten, speed up, and tilt vertically, creating a funnel cloud.Tornadoes are dangerous—even deadly—because of their high winds and subsequent flying debris.

Hurricanes:hurricane is a swirling, low-pressure system that develops over the tropics with sustained winds that have reached at least 74 miles per hour.

Warm, moist air near the ocean's surface rises upward, cools, and condenses, forming clouds. With less air than before at the surface, the pressure drops there. Because air tends to move from high to low pressure, moist air from surrounding areas flows inward toward the low-pressure spot, creating winds. This air is warmed by the ocean's heat and the heat released from condensation, so it rises. This starts a process of warm air rising and forming clouds and surrounding air swirling in to take its place. i hope helps u marks as brainlist

D. Ultraviolet radiation is absorbed, and fewer air molecules cause the thermosphere to heat quickly.

Answers

Answer:

d

Explanation:

suns ultraviolet rays are absorbed in the thermosphere

The contributing factors cause the thermosphere to be warmer than the mesosphere is ultraviolet radiation is absorbed, and fewer air molecules cause the thermosphere to heat quickly.

What are the effects of ultraviolet radiation?

The experiment that ultraviolet light made plants grow more slowly is the experiment most likely has greater reliability in which the experiment repeated several times and each time found that plants grow slightly slower with ultraviolet rays because the experiment was repeated with the same.

The main effect of ultraviolet light on plant growth is during photosynthetic active radiation under high level, UV -B light increases the net plant photosynthesis in several plant species.

Higher production of dangerous radiation can be induced under both UV-B and high PAR in young and old plant leaves.When UV light is obtained by plants resins production increases and plant become richer in smelling and better in tasting.Due to increase in resin production the plant is protected  from pests and diseases.

Therefore, The contributing factors cause the thermosphere to be warmer than the mesosphere is ultraviolet radiation is absorbed, and fewer air molecules cause the thermosphere to heat quickly.
