How do ants use formic acid to stay alive

Answer 1

Answer: "When the crazy ants were dabbed with fire ant venom, they would go off and do this ... arid soils or severe freezes, that will be too harsh for them to survive.

Answer 2

Answer: Invasive “crazy ants” are rapidly displacing fire ants in areasacross the southeastern US by secreting a compound that neutralizes theother’s venom.It’s the first known example of an insect having the ability to detoxify another insect’s venom, researchers say.The crazy ant invasion is the latest in a series from the southernhemisphere and, like its predecessors, will likely have dramatic effectson the region’s ecosystems. Known for their painful stings on humansand other animals, fire ants dominate most ant species by dabbing themwith powerful, usually fatal venom. A topical insecticide, the venom istwo to three times as toxic as DDT on a per weight basis.invasive filesBut when a crazy ant is smeared with the venom, it begins anelaborate detoxification procedure—it secretes formic acid from aspecialized gland at the tip of its abdomen, transfers it to its mouth,and then smears it on its body.In lab experiments, exposed crazy ants that were allowed to detoxifythemselves had a 98 percent survival rate. This chemical counter-weaponmakes crazy ants nearly invincible in skirmishes with fire ants overfood resources and nesting sites. The research is published in thejournal science express.“As this plays out, unless something new and different happens, crazyants are going to displace fire ants from much of the southeastern USand become the new ecologically dominant invasive ant species,” says EdLeBrun, a research associate with the Texas invasive species researchprogram at the Brackenridge Field Laboratory at the University of Texasat Austin.Researchers have previously reported that where crazy ants take hold,the numbers and types of arthropods—insects, spiders, centipedes, andcrustaceans—decrease, which is likely to have a ripple effect onecosystems by reducing food sources for birds, reptiles, and otheranimals. They also nest in people’s homes and damage electricalequipment.

Answers

The statement that describes an insulator is A. It has a high resistivity because it opposes the movement of electrons.

Insulators simply mean the electrical equipment that are used to support electrical conductors as well as separate them as they do not allow the passage of current.

In an electrical insulator, the electric current doesn't flow freely. It possesses a high resistivity because it opposes the movement of electrons.

A strand of 10 lights is plugged into an outlet. How can you determine if the lights are connected in series or parallel? A) Unscrew one light. If the other lights stay on, it's a series circuit. B) Unplug the strand. If the first light stays on, it's a series circuit. C) Unscrew one light. If the other lights turn off, it's a series circuit. D) Cut the strand in half. If the plugged in half stays on, it's a series circuit

Answers

Answer: C) Unscrew one light. If the other lights turn off, it's a series circuit.

Explanation:

In a series circuit, all the components in the same path. The current in the entire circuit is same. The voltage drop across each component is different. If one component does not work, the entire circuit breaks and other components also stop working. On the other hand, in a parallel circuit, voltage drop across all the components is equal. Trouble in one component does not effect other components.

Hence, to check whether the lights are connected in series or in parallel, one light should be unplugged and if the other lights still work, it means they are connected in parallel otherwise in series. Thus, correct option is C) Unscrew one light. If the other lights turn off, it's a series circuit.

this answer is c because a series series circuit only has one path unlike a parallel circuit which has multiple circuits.

A stone is dropped from rest from a tall building how fast is the stone moving after 5s

Answers

Answer:

The final velocity is -49.05 meters per second.

Explanation:

Let's use an equation of constant acceleration:

$v=v_0+at\nv=v_0-gt\n$

Where a is the acceleration and g is the acceleration caused by gravity.

Since the object is being dropped from rest, $v_0=0 (m)/(s)$ .

We're looking for the speed after 5 seconds, so $t=5 s$ .

$v=(0(m)/(s))-(9.81(m)/(s^(2)))(5s)\nv=-49.05(m)/(s)$

So the final velocity is -49.05 meters per second.

Which has more Potential Energy a car parked on the top of the hill,a person on the top of the same hill sitting down eating a sandwich, or a man running fast at the bottom of the same hill?

Answers

As long as you're talking about gravitational potential energy the car at the top of the hill is correct. If you're talking about chemical potential energy, it would depend on how much gas is in the tank and what the contents of the sandwich were.

Answer:

50.2 m/s

Explanation:

First of all, we need to find the time it takes for the ball to reach the ground.

The vertical position of the ball at time t is given by

$y(t) = h +ut + (1)/(2)gt^2$

where

h = 120 m is the initial height

u = 0 is the initial vertical velocity

g = -9.8 m/s^2 is the acceleration of gravity

The ball reaches the ground when y = 0. Substituting into the equation and solving for t, we find the time of light:

$0=h+(1)/(2)gt^2\nt=\sqrt{-(2h)/(g)}=\sqrt{-(2(120))/(-9.8)}=4.95 s$

The vertical component of the velocity of the ball changes following the equation

$v_y(t) = u+gt$

Substituting t = 4.95 s, we find the final vertical velocity of the ball just before reaching the ground:

$v_y=0+(-9.8)(4.95)=-48.5 m/s$

where the negative sign means the direction is downward.

We also can find the horizontal component of the velocity: since we know the horizontal distance travelled is d = 64 m,

$v_x = (d)/(t)=(64)/(4.95)=12.9 m/s$

And the final speed is calculated as the magnitude of the resultant of the two components of the velocity:

$v=√(v_x^2+v_y^2)=√(12.9^2+(-48.5)^2)=50.2 m/s$
