Q1: What is an electromagnet?

A1: According to Microsoft Dictionary, a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.

__________________________________________________________

Q2: What are the parts of an electromagnet?

A2: According to Sciencing, Significance. Electromagnets are a vital part of everyday life.

Operation. Electromagnets behave the same way as regular magnets.

Construction. The basic components of an electromagnet are a wire and a power source.

Special Types of Electromagnets. Solenoids are electromagnets that are in the form of a helix.

__________________________________________________________

Q3: How is an electromagnet useful when compared to a permanent magnet?

A3: According to Toppr, The main advantage of an electromagnet over a permanent magnet is that we can quickly change the magnetic field by controlling the amount of electric current in the winding. The magnetic field created by an electromagnet is proportional to both the number of turns in the winding and the current in the wire.

Answer:

Diffusion, Facilitated Diffusion

Explanation:

Diffusion is a form of passive transport of matter across the cell membrane. Diffusion is a transport substance from the middle with already in the middle with a lower concentration until the concentrations are equalized. The magnitude of the diffusion is proportional to the chemical gradient.

Facilitated diffusion, also called carrier-mediated diffusion, is the movement of molecules across the cell membrane via special transport proteins, which are incorporated into cell membranes.

The mixture of two parent's dna and structure

Explanation:

My personal theory is when the dna of two parents mix it tries to make a child with a body structure similar to the parents. The mixing of the body structures was messed up and that is how we evolved, because over time our bodies grew due to the dna of our ancestors. This theory is most likley wrong, but might be close to right.

Upon examining a sample consisting of 100 cells, you find the following distribution of cell phases. If you know that the cell cycle for this type of cell takes two hours, how long, on average, does the cell spend in prophase

Answers

Answer:

the time that cell spend in prophase is 30 minutes

Explanation:

The computation is shown below:

= Number of cell ÷ sample

= 25 ÷ 100

= 1 ÷ 4

Now it takes two hours

So,

= 1 ÷ 4 × 2 hours

= 0.5

This 0.5 represent the 30 minutes

Hence, the time that cell spend in prophase is 30 minutes

Answer: 30 minutes

Why does the world store nuclear waste and not
just shoot it into the Sun or deep space?

Answers

Answer:

One is that this is very, very expensive. When the Parker Solar Probe was sent to take measurements of the Sun this year, it cost US$1.5 billion just for a spacecraft the size of a small car to get that far.

It seems simple to shoot an object towards something as big as the Sun - which is 1.3 million times the size of Earth. But it’s actually very hard. The Parker Solar Probe (a NASA robotic spacecraft en route to investigate the outer corona of the Sun) has to swing past the planet Venus seven times to slow itself down enough to get close to the Sun.

The other reason is that rockets sometimes blow up on the launch pad, or in the atmosphere. This would release the waste into the environment and make the problem even worse.

How many strands of mRNA are transcribed from the two “unzipped” strands of DNA?

Answers

Answer:

Since DNA is double-stranded, two different RNA molecules could in principle be transcribed from any gene, using each of the two DNA strands as a template.

Explanation:

During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA

the starting molecule for glycolysis is

Answers

Answer:

The starting molecule for glycolysis is glucose.

Explanation:

I think this picture might show why ⬇︎

The starting molecule for glycolysis is glucose.

In the end, glucose is split into two pyruvate molecules through glycolysis. Glycolysis can be thought of as having two phases that take place in the cytosol of cells. Due to the use of two ATP molecules, the first phase is known as the "investment" phase, and the second phase is known as the "payoff" phase.

Glycolysis is crucial because it is the metabolic pathway by which glucose is converted into energy for the cells. For all living things, glucose is the most important source of energy. The majority of cells in the human body use glucose as their preferred fuel: Red blood cells can only fuel themselves with it.

2.Biotic factors are dependent on abiotic factors for food and protection.

3.Abiotic factors affect the type and number of organisms that live in a particular ecosystem.

Explanation:

An ecosystem is an environment that contains both living and non-living parts that actively interacts together.

The living part of the ecosystem is the biotic factors and the non-living parts are the abiotic factors.

The biotic components actively depends on the abiotic component for nourishment. This is exemplified through the process of photosynthesis. Also, the shelter of organisms are derived from the abiotic factors. The abiotic factors have significant impact on the type and number of organisms that live in an ecosystem.
