What are the importance of physics

Answers

Answer 1

Answer:

Answer:

Physics contributes to the technological infrastructure and provides trained personnel needed to take advantage of scientific advances and discoveries. Physics is an important element in the education of chemists, engineers and computer scientists, as well as practitioners of the other physical and biomedical sciences.

Explanation:

Answer:

The correct option is (B)mantle convection

Explanation:

Tectonic plates at the earth's surface move because of the intense heat in the Earth's core. this heat causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell and producing a movement called mantle convection which is the slow creeping motion of Earth's solid silicate.

The answer is B. Mantle convection.

An organism's scientific name consists of...

Answers

Answer:

binomial nomenclature.

Explanation:

This means that an organism's scientific name is a combination of two terms.

The first is the name of the organism's genus, and the second is the name of the organism's species

together the genus and the species create the name of a single organism.

How do ants use formic acid to stay alive

Answers

"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.

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.

If the length of the ramp is 2m and the height of the ramp is 1m , what is the mechanical advantage?

Answers

Answer:

Mechanical Advantage is 2

Explanation:

M.A = length of ramp / height of ramp

= 2/1
