What happens when black holes accrete matter too quickly?

Answers

Answer 1

Answer:

These objects are called quasars, or active galactic nuclei. However, most black holes are too compact to pull such material — which is mostly gas — in immediately. ... Eventually, the gas is moving so fast that it gets extremely hot and luminous, generating radiation that we can often see from Earth.

Which material would result in the least amount of energy transfer?

A reflector that is bright in color and smooth.
A reflector that is dark in color and smooth.
An absorber that is bright in color and rough.
An absorber that is dark in color and rough.

Answers

The least amount of energy transfers by a reflector that is dark in color and rough is the correct option D.

A common example of energy transfer that we see in lifestyle is the transfer of kinetic energy—energy-related to motion—from one moving object to a stationary object via work.

Thermal energy transfers occur in three ways:

ConductionConvectionRadiation

Energy can't be created or destroyed, meaning that the entire amount of energy within the universe has always been and can always be constant.

Energy is transferred by one among the subsequent four sorts of energy pathways:

Mechanical work – a force moving an object through a distance
Electrical work – charges moving, to a possible difference
Heating temperature difference caused electrically or by reaction
Radiation energy transferred as a wave eg. light, infrared, sound - the Sun emits light radiation and infrared.

Therefore, the correct option is D means a reflector that is dark in color and rough results in the least amount of energy transfer.

What do you think some of the negative consequences of gender socialization could be?

Answers

Gender socialization is the process by which individuals learn and internalize the norms, attitudes, and behaviors associated with their gender. While gender socialization can have some positive effects such as promoting socialization and community building, it can also have negative consequences.

One negative consequence of gender socialization is the reinforcement of gender stereotypes. Stereotypes are oversimplified and often inaccurate beliefs about groups of people, and they can lead to discrimination and prejudice. Gender stereotypes can limit individual choices and opportunities, as well as contribute to gender-based violence and other forms of inequality.

Another negative consequence of gender socialization is the pressure to conform to traditional gender roles and expectations. This pressure can limit individual expression and creativity, and it can also contribute to mental health issues such as anxiety and depression.

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water

Answers

The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.

Why do polar molecules repelled by the phospholipid bilayer?

Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.

What component of the phospholipid bilayer is water-repellent?

While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

What was fingerprint?

A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Fingerprints on surfaces such as glass or metal are caused by moisture and grease on the finger. Ink or other substances transferred from the peaks of friction ridges on the skin to a flat surface such as paper can be used to create deliberate imprints of whole fingerprints.

Fingerprint records generally include impressions from the pad on the final joint of the fingers and thumbs, while fingerprint cards may also include sections of the fingers' lower joint regions.

What are the stages of bee development (eggs,larvae,pupae)

Answers

The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.
