Higher death rates. ...

Dirtier air. ...

Higher wildlife extinction rates. ...

More acidic oceans. ...

Higher sea levels.

Explanation:

Answer:

Global warming and climate change are two of the most pressing issues facing our planet today. The increase in temperature and changes in weather patterns have caused a significant impact on the environment and the different regions of the world.

In the Arctic, the ice is melting at an alarming rate, leading to rising sea levels. This has devastating effects on the wildlife that depend on the ice for survival. Polar bears, for example, are struggling to find food as the ice they hunt on disappears.

In Africa, climate change is leading to droughts and food shortages. This is particularly devastating for the millions of people who depend on agriculture for their livelihoods. Without adequate rainfall, crops fail, leading to famine and displacement.

In Southeast Asia, rising sea levels and more frequent storms are causing coastal erosion and flooding. This is leading to the loss of land and homes, as well as damaging critical infrastructure such as power plants and hospitals.

Overall, global warming and climate change are causing significant damage to the environment and the people and animals that depend on it. Urgent action is needed to mitigate the effects of these phenomena and prevent further damage to our planet.

How will the increase in the tuna population affect the other populations? Be sure to explain whether the dolphin population, the squid population, and the herring population will change, and why.

Answers

Complete question:

Scientists have been studying four populations in one area of the Atlantic Ocean. In this area, both tuna and dolphins eat squid, and squid eat herring (a type of fish).

The data shows that recently the tuna population increased. How will the increase in the tuna population affect the other populations? Be sure to explain whether the dolphin population, the squid population, and the herring population will change, and why.

You will find the image in the attached files.

Answer:

Tunas´ population increasesSquids´ population decreases because more tuna eat themDolphins´ population decreases because there are fewer squids availableHerrings´ population increases because they do not suffer predation by squids.

Explanation:  

In the trophic web occurs a process of energy transference through different organisms placed at different levels.  Each level feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.

If any of the links change their population size (increasing it or decreasing it), it affects the superior links and the immediately anterior link.

In the exposed example of the trophic web, tuna feeds on squids. If the tuna population increases in size, there will be more individuals feeding on squids. Squids will be affected because too many animals are eating them, and they will not have enough time to reproduce and recover the normal population size. The mortality rate by predation is higher than the natality rate, meaning that the squid population will decrease.

Dolphins also feed on squids. But as the tuna population increases in size, competition for squid prey will be higher. Both species (tuna and dolphins) will compete for food. But tuna will eat more squids, and hence, dolphins will be affected and decrease in population size.

Usually, herrings are eaten by squids. But as the squids' population decreases, herrings will not suffer from predation, and their population will increase in size.

So, to sum up:

Tunas´ population increasesSquids´ population decreases because more tuna eat themDolphins´ population decreases because there are fewer squids availableHerrings´ population increases because they do not suffer predation by squids.

What is the relationship between force, mass, and motion?

Answers

Answer: If an object is accelerating, then Force = Mass x Acceleration. If it is moving at a constant speed, then Kinetic Energy = 1/2 mass x velocity squared but in this case, there is no force acting on the object. Perhaps this will help understand the relationship between force and mass. Force is anything that acts on an object, from a person pushing on something to gravity holding the Earth in orbit around the Sun, to cause it to change speed or direction. If there is no change in speed or direction, then no force is acting on it. This relates to mass in the following way. THE GREATER THE MASS, THE GREATER THE FORCE NEEDED TO MAKE THAT MASS CHANGE SPEED OR DIRECTION. Think of it like this; what takes more force to push up a hill, a car, or a bicycle. The bicycle has less mass and therefore requires less force to push it.

Force = Mass x Acceleration if an object is accelerating.

What is Motion?

Kinetic Energy = 1/2 mass x velocity squared if it is moving at a constant pace, yet there is no force acting on the item in this scenario.

This will make the connection between force and mass more clear. Any action that exerts force on an object—from a person pushing something to gravity keeping the Earth in its orbit around the Sun—to change its speed or direction is referred to as force.

No force is acting on something if there is no change in its direction or speed. The following is how this relates to mass. The force required to cause a mass to change speed or direction increases with mass.

Therefore, Force = Mass x Acceleration if an object is accelerating.

The organelle found in both animal and plant cells that is clear but contains dissolved nutrients and ions is - vacuole as it stores nutrients, ions, water, and waste.

A vacuole is a double membrane-bound small cavity or space in the tissues of an organism containing air or inorganic or organic molecules as fluid present in the cytoplasm of a cell.

This organelle usually containing food or nutrients, ions, and waste in the fluid form, inside of both plant and animal cells.In the animal cells, these are present in small sizes and more than one whereas in the plants a single large vacuole is found that sometimes takes up most of the space of the cell.

It takes 600 J of work to lifta crate straight up but 1,200 Jto pushthat crate up a ramp to the same height. What's the efficiency of the ramp?

Answers

Answer:

50 percent

Explanation:

The efficiency of ramp can be found by using this formula

(Output work/input work)*100.

Amounts of work to lift up = 600j

Amount of work bro take up to same height = 1200j

Efficiency of ramp = (600j/1200j) * 100

= 0.5 x100

= 50 percent

Therefore from the calculations above, the efficiency of this ramp is 50 percent

Strength and quantity of electromagnetic can be controlled by currents of electricity because it depends on the electric current. Electromagnets is to be controlled by controlling the electric current.

The quantity of current flowing through the coil can also control the strength of the electromagnetic field around that coil.

What do your muscle cells do when they run out of oxygen for respiration?

Answers

Explanation:

When your muscle cells run out of o2 4 respiration, it relies on stored fat or lipids for energy..(glycolysis) ...

Normally this transition does not last long because muscles also depend on glucose for energy..

When muscle cells run out of oxygen for respiration, they switch to anaerobic respiration, producing lactic acid as a byproduct.

When oxygen runs gone, muscle cells switch to anaerobic respiration. Aerobic respiration generates ATP from oxygen. Muscle cells switch to anaerobic respiration during severe activity or low-oxygen settings.

Muscle cells use glucose to respire anaerobically. Glycolysis generates ATP, although less efficiently than aerobic respiration. Lactic acid, a consequence of anaerobic respiration, can build up in muscles and cause tiredness, discomfort, and burning.

Anaerobic respiration offers short-term energy but is unsustainable. Muscle cells will resume aerobic respiration to efficiently create ATP and remove lactic acid once oxygen is available.
