Black holes are inviable because they don't reflect light? true or false

Answers

Answer 1

The gravity of a black hole is so strong that not even light can escape. Even if a bright star is shining right next to a black hole, you cannot see the black hole. Instead of reflecting the light as other objects do, the black hole just swallows the starlight forever.

Characteristics of living things
Respond to stimulus-Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.)
Cells and cellular structure-A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Genetics-how traits are passed from parents to their offspring. The passing of traits from parents to offspring is known as heredity, therefore, genetics is the study of heredity.
Metabolism-the chemical reactions in the body's cells that change food into energy.
Homeostasis-the state of steady internal, physical, and chemical conditions maintained by living systems.
Adaption-the biological mechanism by which organisms adjust to new environments or to changes in their current environment.

What is a natural way to control an aphid population?

release ladybugs into habitat
praying mantis
insecticide

Answers

Answer:

I would say that the answer is A, or releasing ladybugs into a habitat.

Explanation:

This is the only "natural" way to control an aphid population. However, please note that as well as ladybugs, praying mantis's also eat aphids. But, the answer choice doesn't describe the option very well, so that is why I say that it is A.

Hope it helps!

The natural way to control an aphid population is release ladybugs into habitat. The correct option is 1.

What is Ladybug?

Ladybugs are natural aphid predators that can consume large numbers of them, assisting in population control without the use of harmful chemicals.

A natural way to control an aphid population is to release ladybugs into the aphid's habitat.

Although praying mantises are natural predators of aphids, they are less effective at controlling their population than ladybugs.

Insecticides, on the other hand, are chemical treatments that can be harmful to both beneficial insects and the environment.

As a result, using insecticides to control aphid populations is not a preferred method, particularly in natural or organic settings.

Thus, the correct option is 1.

The human foot has three arches, but the chimpanzee foot only has one. Therefore, option B is correct.

What is the difference between humans and chimpanzees?

Humans have a significantly more developed brain, better motor control, and less body hair. The human brain's neural network has been found to be much more complex, and spindle neurons have also been discovered.

Nucleotide-for-nucleotide was discovered to differ from the human genome with which it was compared by roughly 1.23 percent. This equates to roughly 40 million changes in our DNA, with half most likely the result of mutations in the human ancestral line and the other half occurring in the chimpanzee line since the two species split.

The human foot has three arches, but the chimpanzee foot only has one. Therefore, option B is correct.

In this case, we have a large population of lizards that live on an island. These particular lizards can either have an all-green tail or a tail with a black tip. In the large population there are many of each type, but one day, two green-tailed lizards and three lizards with black-tipped tails were picked up by a sailor and dropped off on an island that had no lizards of this kind. It was noted that the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators. The lizards began to breed and eventually produced their own large population after a few years. Make a prediction about what you might find if you visited this island after several years based on what you have learned.

PLEASE HELP!!!

Answers

This is a complicated question that's a little easier if you break it down!

Island One:

- Lizard tails are all green or black tipped.

- This island has many of each type.

Sailors Moved:

- two green-tailed lizards

- three black-tipped lizards

On Island Two, we know that the black-tipped lizards are more likely to survive since the question tells us that "the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators".

The green tailed lizards do not have this advantage, and the predators are eating more of them because of this (especially if there are a lot of predators!).

We also know that the lizards on the island were able to reproduce and form a large popuation- not all of them were eaten by predators.

Based on this information we can predict:

There are going to be a lot more black tipped lizards (or they may all be black tipped lizards) because they have an advantage in surviving longer.

Moving a book to a lower shelf decreases potential energy.
True
False

Answers

Answer:

True

Explanation:

Moving a book so the potential energy of the system decreases is a true statement.

What is potential energy?

A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.

A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.

Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.

Therefore moving the book to a lower shell change potential energy, which decreases.
