how can energy from the motion of the crank on a hand-powerd flashlight produce heat?

Answers

Answer 1

Answer:

When you manually crank the flashlight, a coil of wire inside the generator converts the mechanical energy into electrical energy. This allows an electrical current to flow through the flashlight, thus lighting the bulb of the flashlight.

Answer 2

Answer:

It's called thermal energy. The energy that comes from the temperature of the heated essence is called thermal energy.

Coracias garrulus is a blue bird with an orange-brown back. The offspring of this bird have an effective defense mechanism. The young birds vomit and cover themselves in a foul-smelling orange liquid when they sense a threat by predators. Which two systems alert the young bird to the danger and help produce the vomit it uses as a defense

Answers

Answer:

The correct answer is - Nervous and digestive systems.

Explanation:

Coracias garrulus is a bluebird that has a unique defense mechanism in which it senses the danger or threat they vomit and cover themselves with their foul-smelling orange-yellow vomit.

The orange vomit or liquid store in the digestive system of the bird and when the bird's sense threatens it activates its nervous system which then intern sends a signal to the digestive system and the urge of vomit on its young ones and cover in that.

The nervous and digestive systems are the body systems that alert the young bird to danger and help produce the vomit it uses as a defense.

The nervous system is a body system by which animals coordinate actions and sensory information such as alert signals.

The nervous system transmits signals to different parts of the body including the digestive system.

The digestive system is the body system that acts to digest foods, having reflexes that allow to eliminate them by vomiting.

In conclusion, the nervous and digestive systems are the body systems that alert the young bird to danger and help produce the vomit it uses as a defense.

Answers

Answer:

A-T base pairs in a DNI double helix are chemically distinct from G-C base pairs.

Explanation:

Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.

In the DNA molecule, Adenine (Purine) always form pairs with Timine (Pyrimidine), while Guanine (Purin) form pairs with Cytosine. Two hydrogen bonds unite the pair A-T, while three of them unite the pair G-C.

The structure of these bases is different hence, the chemical structure of the pairs is also different.

Give an example of how using soil, trees, or air might result in a tradeoff

Answers

Answer:

As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere. Trees provide many benefits to us, every day.Explanation:

sorry if that doesnt help but hopefuly it does:)

By using soil, trees and air will result in a trade off due to increasing in one factor and decreasing in another factor.

Using soil, trees and air result in a tradeoff by using the carbondioxide gas in the atmosphere. The trees increase in high and vegetative growth by decreasing the carbondioxide gas in the atmosphere. In tradeoff, one thing increases, and the another must decrease.

So if the trees grow in size the concentration of carbondioxide gas decreases due to the process of photosynthesis by the tree so we can conclude that using soil, trees and air will result in a trade off due to increasing in one factor and decreasing in another factor.

Are gender traits completely a result of societal expectations?

Answers

[tex]\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star[/tex]

No. Gender traits in humans are largely determined by biophysical processes. There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary.

But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to.

This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development

Which population would be most likely to increase if roseate spoonbills
disappeared from the community?
O A. Mangrove
O B. American crocodile
OC. Roseate spoonbill
OD. Mangrove tree crab

Answers

the population which would be most likely to increase would be the mangrove tree crab for they won’t be hunted no longer by the roseate spoonbills and therefore their numbers will increase

Answer:

D. Mangrove tree crab. There would be a drop in the predators that feed on them. Crocodile populations would drop to food shortage, and mangroves might also suffer from the high crab population, so only D is correct.

Natural selection causes what to occur?
1. evolution
2. survival of the fittest
The law of independent assortment
3. Mendel's law of segregation
4. genetic drift

Answers

Answer:

(1.) Natural selection causes evolution to occur.

Explanation:

Over time, the naturally occurring variation within a population that arise from mutations, alter in frequency. Some of these variants or traits, may confer advantages to certain organisms, allowing them to reproduce and pass on genes more successfully. These traits become fixed within the population, and eventually the individuals evolve to form a species.

Natural selection, acts on evolution, for or against traits.  It ensures that individuals with traits well-suited to their environments and reproductive fitness survive.      

Answer:

1. evolution

Explanation:

Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.
