How long does it take for mammals to evolve into a distinctly new species? What changes occur over
this time?

Answers

Answer:

i hope this helps <3

Explanation:

A new study by Matt Davis at Aarhus University throws these losses into stark relief. He estimated how long it would take for mammals to evolve enough new species to replace the ones that we have eradicated. And his most realistic answer is somewhere from 3 million to 7 million years.

The time that would be taken for mammals to evolve into a distinctly new species is 3 million to 7 million. The changes that will occur will be mental and physical changes.

What is evolution?

Evolution is a process of changing human characters or other animal characteristics over time. Evolution happens with time, and it is a natural process.

Species is a term that refers to different animals and plants living in the environment. Organisms of the same species can reproduce with each other. Other species are different from the one species.

Evolution in every species occurs with time and environmental conditions for better survival in the environment.

Thus, it would take mammals between 3 million and 7 million years to evolve into a wholly new species. The alterations that take place will affect both the mind and the body.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement best describes an environmental consequence of this process?

A. Chemicals added to the liquid can contaminate groundwater.
B. Wastewater is contaminated with oil and becomes sludge in landfills.
C. Water vapor is released into the air, which is considered a greenhouse gas.
D. Heavy metals are released into surrounding soil, poisoning local vegetation.

Answers

Answer:

Option A, Chemicals added to the liquid can contaminate groundwater, this statement best describes an environmental consequence of this process.

Explanation:

Fracking is a process of digging fossil energy sources, which need a lot of water and uses local water resources. It is drawn with high-pressure water, sand and elements, creating high pressure to block the porous rock and discharge gas. The  spill itself stops energy from the drilling position, and may even make earthquakes, mainly due to the pumping of overflowing wastewater into porous rock types such as limestone. The most significant result of water distortion is on groundwater.

• Chemicals added to the liquid can contaminate groundwater.
O Wastewater is contaminated with oil and becomes sludge in landfills.
Water vapor is released into the air, which is considered a greenhouse gas.
Heavy metals are released into surrounding soil, poisoning local vegetation

Answers

The correct answer is that chemicals added to the liquid can contaminate groundwater.

Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.  

The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

Moosehead Lake in Maine is a beautiful lake, spanning 74,890 acres with a maximum depth of 246 feet. The most sought-after fish to be found in Moosehead Lake are: Landlocked salmon, lake trout, brook trout, and burbot. According to Tim Obrey, a regional fisheries biologist with the Maine Department of Inland Fisheries and Wildlife, the fishing at Moosehead declined from phenomenal to just "really good" during the late 1980s, but has rebounded due to careful management. This table shows the populations of three major fish in Moosehead Lake over a 30 year period. Moosehead Lake was illegally stocked with smallmouth bass in 1970. Fish Populations in Moosehead Lake Year Smallmouth Bass Salmon Lake Trout

Smelts are the primary food source for lake trout and salmon in Moosehead. In the late 1980s, we documented a dramatic increase in the abundance of wild lake trout in Moosehead Lake. Swelling lake trout numbers taxed the forage base and the smelt population took a dive. What would be appropriate action for Wildlife Management to make to correct the problem? Choose ALL that apply.

B) One hundred small, one-hectare size areas should be conserved
C) Native species should be maintained or planted within the greenspace to promote biodiversity.
D) Exotic species should be cultivated and planted to increase biodiversity in the protected greenspace.
E) The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.

(WILL GIVE BRAINLIEST WHOEVER CAN ANSWER RIGHT!!!!!!)

Answers

When one of the trophic web links disappears, it affects the whole chain. In management programs it is important to consider these consequences to keep the whole ecosystem equilibrium. In the exposed situation, Native species should be maintained or planted within the greenspace to promote biodiversity and The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.

--------------------------------------

The trophic chain is the energy transference process that involves different organisms, from autotroph or producers, to the consumers or decomposers.

The disappearance of one link affects the whole system. The direct superior link does not have enough food supply, while the immediately anterior link is beneficiated for not being eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link. Top-down control refers to scenarios where superior predators control the structure and dynamic of an ecosystem.

It is necessary and significant to consider these modifications in the whole ecosystem while planning management actions to keep an equilibrium.

In the exposed example we know that the most wanted species are

Landlocked salmon, lake trout → which increased its population size sharply over the last yearsbrook trout, and burbot

Smelts, which are the primary food source for lake trout and salmon, decreased in population size significantly.

Finally we know that smallmouth bass was introduced in 1970.

This information suggests that the decrease in smelts' population is due to the predation of the species by the lake trout, which population increased sharply in size. The change on smelts' population size, might affect the blook trout and salmon populations, that also feed on semelts, and might also affect other species occupying inferior levels.

When implementing a management program, it would be necessary to promote biodiversity by growing native species in greenspaces and ensure their survival and reproductive succes. In the exposed case, it is necessary to preserve smelts' population, so it would be also necessary to remove from these green spaces the secondary consumers -trouts and salmon- that feed on them, to ensure the smelts' population growth and recovery.

8. At the surface of a swimming pool a 2.0 L balloon is under 760 mmHg of pressure. If that balloon is taken to the

0.45 L
b. 1.6L
2.4 L
d. 95 L
a.
C.
voru

Answers

The new volume of the balloon is 1.6L

HOW TO CALCULATE THE FINAL VOLUME:

Using Boyle's law, which states that the pressure of a given gas is inversely proportional to its volume i.e PV = K

Boyle's law equation is as follows:

P1V1= P2V2

Where;

P1 = initial pressure (mmHg)P2 = final pressure (mmHg)V1 = initial volume (L)V2 = final volume (L)

According to this question,

P1 = 760mmHg

V1 = 2L

V2 = ?

P2 = 950mmHg

Using P1V1 = P2V2

760 × 2 = 950 × V2

1520 = 950V2

V2 = 1520/950

V2 = 1.6L

Therefore, the new volume of the balloon is 1.6L
