When prokaryotic bacterial cells undergo cell division, the single circular chromosome replicates to form a second chromosome. This new chromosome, like the original, attaches to the plasma membrane. Next, the plasma membrane pinches inward, and a cell wall forms across the middle of the cell to separate the two chromosomes and form two daughter cells. How does cell division in bacteria differ from mitosis in eukaryotes?

The Life Cycles of Stars: How Supernovae Are Formed

It is very poetic to say that we are made from the dust of the stars. Amazingly, it's also true! Much of our bodies, and our planet, are made of elements that were created in the explosions of massive stars. Let's examine exactly how this can be.

Life Cycles of Stars

A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. As the gas spins faster, it heats up and becomes as a protostar. Eventually the temperature reaches 15,000,000 degrees and nuclear fusion occurs in the cloud's core. The cloud begins to glow brightly, contracts a little, and becomes stable. It is now a main sequence star and will remain in this stage, shining for millions to billions of years to come. This is the stage our Sun is at right now.

As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and glows red. The star has now reached the red giant phase. It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths it will take from there.

diagram of the life cycles of low and high-mass stars

The life cycle of a low mass star (left oval) and a high mass star (right oval).

The illustration above compares the different evolutionary paths low-mass stars (like our Sun) and high-mass stars take after the red giant phase. For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.

On the right of the illustration is the life cycle of a massive star (10 times or more the size of our Sun). Like low-mass stars, high-mass stars are born in nebulae and evolve and live in the Main Sequence. However, their life cycles start to differ after the red giant phase. A massive star will undergo a supernova explosion. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different. The force of gravity overcomes the nuclear forces which keep protons and neutrons from combining. The core is thus swallowed by its own gravity. It has now become a black hole which readily attracts any matter and energy that comes near it. What happens between the red giant phase and the supernova explosion is described below.

Answer:

Enzyme- Peptidase/protease

Explanation:

According to this question, a student is conducting an experiment to determine the roles of molecules in metabolic processes such as digestion. Based on what she found out that the molecule, which itself can be broken down into amino acids, can also break down proteins into amino acids, this suggests that the molecule being described is a PROTEOLYTIC ENZYME.

This is because an enzyme is made up of proteins which can be denatured or broken down into its simplest unit (amino acids) and also, a substance that breaks down amino acid is said to be PROTEOLYTIC.

However, another observation that the molecule is found in high concentrations in the small intestine was made, hence, the enzyme is a PEPTIDASE OR PROTEASE, which are secreted into the small intestine by the pancreas to aid digestion of proteins.

The size of the image seen by a friend has been 2 mm.

Magnification can be given as the process of enlarging the image to a degree unlike the physical and the apparent size. The use of magnification glass has been forming the enlargement of the images or objects.

The magnification can be given as:

m = v/u

Where, m = magnification, v = object height, and u = image height

The size of the object (v) = 0.5 mm

The size of the image seen (u) = 10 mm

The magnification (m) of the image seen by a person has been:

m = 0.5 mm / 10 mm

m = 0.05

The image seen by a friend of the object (u) of 0.1 mm with a magnification (m) of 0.05 is:

0.05 = 0.1 mm/ u

u = 0.1 mm/0.05

u = 2 mm

Thus, the size of the image seen by a friend with the magnification same as the person has been 2 mm.

Given parameters:

Mass of rock Tobias found  = 475kg

Volume of initial water  = 2000mL

New volume  = 2025mL

Unknown:

Density  = ?

Solution:

Density is the mass per unit volume of a substance.

Mathematically;

               Density  = [tex]\frac{mass}{volume}[/tex]

Volume of rock = New volume - Initial volume = 2025 - 2000 = 25mL

Now let us convert the mass to g;

     1000g  = 1kg

       So; 475kg will be 475000g

So;

  Density of stone = [tex]\frac{475000}{25}[/tex]   = 19000g/mL or 19000g/cm³

Answer:

destroy the RNA polymerase altogether

prohibit the RNA polymerase from starting initiation

stop the RNA polymerase from moving along the DNA strand.

These are the correct answers

Explanation:

A virus can be stopped from spreading in its host by destroying the RNA polymerase altogether, Prohibition so the RNA polymerase from the starting initiation, and by stopping the RNA polymerase from moving along the DNA strand. Thus, the correct options are A, B, and C.

A virus is a sub-microscopic organism, which is an infectious agent that replicates only when present inside the living cells of an organism by using its replication machinery. Viruses infect all the life forms, from animals and plants to the microorganisms, such as bacteria and archaea.

Viruses can be stopped from spreading in the host body by destroying the RNA polymerase, this RNA polymerase is responsible for the multiplication of RNA from host DNA in an organism. By prohibiting the activity of RNA polymerase from initiating the replication the multiplication of viruses can be stopped. This RNA polymerase moves along the host DNA and forms new strands for the replication purpose.

Therefore, A, B, and C all are correct options.

Answer:

The average energy of motion of particles in a substance is its kinetic energy. Therefore, temperature is the measure of the average kinetic energy of the particles of a substance. The thermal energy of the substance is the total energy of the substance.

Explanation:

We want to explain the relationship between particle motion, temperature, and thermal energy.

First, let's explain the relationship between thermal energy and temperature.

When we have a given object, as we give it thermal energy (there are different ways, like radiation, conduction, etc) the temperature of the object increases.

So we can say that the temperature is a measure of the stored thermal energy.

Now, the relation between temperature and particle motion is more interesting.

As we increase the temperature of a given object, the increase in energy (again, the temperature is related to energy) comes from an increase in the kinetic energy of the particles that make the object.

Thus, when we increase the temperature of something, the particles that conform it move more (remember that the kinetic energy is related to the velocity of the particles). This is why we usually see an increase in the volume when we heat up something.

And also this is why most elements have more volume in the gas phase than in the liquid phase, for example.

These are the relations between thermal energy, temperature and particle motion.

Explanation:

The process in which the exposed "interior" of an apple becomes/turns brown is caused by enzymatic actions in the apple. This browning reaction occurs in many fruits and tubers (like banana and yam). This process requires oxygen to proceed and hence can be restricted by the presence of an antioxidant. Ascorbic acid is an antioxidant that can assist in countering the effect of the oxygen molecules in this browning.

Lemon contains a good amount of ascorbic acid which can assist in counteracting the effect of oxygen and prevent the browning from taking place.
