Which statement best accounts for the decline in bighorn sheep populations? 1. Predators of the sheep decreased in number. 2. Sheep ewes that have shorter, spiked horns increased in number. 3. Human activities directly and indirectly affected the sheep. 4. The sheep were listed as a "species of concern" by Glacier National Park.

Answers

Answer:

The statement which best accounts for the decline of the bighorn sheep population is - " Human activities directly and indirectly affected the sheep."

Explanation: Explaination of the following statements -

Predators of the sheep decreased in number.

Predation is rarely considered a major mortality factor (Wishart 1975, 1978). It is well known that bighorn sheep are preyed upon, but there is little information available on the effect(s) of predation on the populations of bighorn sheep. Numerous citations document the stalking and/or killing of bighorn sheep by a number of predators.

Thus , this statement is not correct.

Sheep ewes that have shorter, spiked horns increased in number -The larger, wild relative of the domesticated sheep is the bighorn sheep. Males are called "rams" and have long spiral horns, while females are called "ewes" with shorter, spike-like horns. With white areas on the muzzle, the back of the legs and around the rump, the coat is short, coarse and usually brown. The sheep will shed its hair once a year to reveal a new coat underneath.

Thus , the statement does not match with the decline of the bighorn sheep.

Human activities directly and indirectly affected the sheep. -: Disease transmission, human interference, overgrazing, and loss of habitat are often cited as factors responsible for decreases in the abundance and distribution of bighorn sheep. these all factors comes under the human activities which directly /indirectly results in the declination of the bighorn sheep.

Hence, this statement is correct .

The sheep were listed as a "species of concern" by Glacier National Park.  

Home to 400 to 600 bighorn sheep, Glacier National Park lists the animal as a "species of concern," that is, at risk of being endangered.  The research has also shown just how sheep-like bighorns could be. They're creatures of habit, that is.  Therefore , the national park indicated the species at risk , but were not responsible for their declination.

Hence, this statement is incorrect.

Therefore , the correct answer is 3 ( Human activities directly and indirectly affected the sheep.)

A marshy area dries up, and most of the organisms in a population of flowers die. However, some of the flowers have adaptations that allow them to survive the change. If the land stays dry, what will the population of flowers be like several generations from now?

A. The population will have greater genetic diversity because the additional stress caused by lower water levels will result in increased immigration.

B. The population will have the same genetic diversity as when the area was marshy.

C. The genetic diversity will be less than in the original population, as more flowers will have the adaptations to live in the drier conditions.

D. The flowers will all die off because they could not survive in the drier conditions.

Answers

Answer:

C

Explanation:

All that is left are the plants capable of surviving in dry conditions; whereas before there were plants that thrived in more marshy conditions. Therefore decreased genetic diversity. The adaptations of the plants will be much less diverse.

Hydrogen bonds can be found between no other molecules except water.


Answers

Answer:

Without hydrogen bonds, water molecules would move faster more rapidly, with less input of heat energy, causing the temperature to increase more for each calorie of heat added.

Explanation: This would also greatly reduce the amount of heat energy needed for phase changes from ice to liquid, and from liquid to vapor.

Answer: Not really a question but....Two molecules of water can form a hydrogen bond between them that is to say oxygen-hydrogen bonding; the simplest case, when only two molecules are present, is called the water dimer and is often used as a model system.

Answer:

Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.

Explanation:

A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.

The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.

    None of the other options are correct, as they involve more or the same use of fossil fuels per person.

5x + 11 = 8x + 20

By substituting,

5x - 8x = 20 - 11

-3x = 9

x = -9 / 3

x = -3

So the correct option is D

Which statement is true about oxygen and nutrient levels of rivers? TIMED TEST

Your answer:

Fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.


Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.


Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.


Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.

The warming of the atmosphere by the trapping of heat being radiated to space is called
a)condensation
b)evaporation
c)the greenhouse effect
d)radiation

Answers

Answer:

The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. Solar energy absorbed at Earth's surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it.
