a control plate in your particular case is a ampicillin plate with no inoculation of your transformed bacteria. its purpose to make sure that during the process of handling the plate there were no contamination by bacteria in the surrounding.

Because although the flies could not lay the eggs on the meat because they were to big to get through the netting they could lay them on the netting knowing that the maggots when they hatched would be small enough to fit through the netting holes to get to the meat therefore being able to nurish themselves.

Both. Rocks are made of minerals.

Besides the gases that comprise air, air can also contain variable amounts of water vapor, characterized by the term, "relative humidity". Because the amount of water vapor held in air can change, it is simpler and more sensible to express component gas percentages on the basis of dry air.

The smallest unit of a substance that has the properties would be either an atom, or more probably a molecule. An atom does not ordinarily exist by itself in nature.

Examples of mass movements include protests, civil rights movements, labor strikes, and social justice movements. These movements involve a large number of people coming together to create change and advocate for a common cause.

Mendel conducted experiments crossing pea plants with different traits, such as flower color and seed texture. He observed that certain traits were dominant over others, and traits were inherited independently of each other. This led to the discovery of his laws of inheritance.

When switching to a high power objective, the field of view becomes smaller and the depth of field becomes shallower. This can make it harder to keep the object in focus due to the increased sensitivity to small movements. Additionally, the increased magnification may require more precise adjustments to the focus to keep the object in view, making it easier to lose sight of the object.

On average, a person's mouth can hold about 1-1.5 teaspoons of water comfortably. This would equate to roughly 75-115 drops of water, depending on the size of the droplets.

Centinewton is a unit of force equal to one hundredth of a newton. It is often used to measure small forces, such as in scientific experiments or to calibrate instruments.

Phase difference in wave propagation results in interference patterns. When waves with a phase difference interact, they can either reinforce each other (constructive interference) or cancel each other out (destructive interference), affecting the overall amplitude of the resulting wave. This phenomenon is commonly observed in various wave systems, such as light and sound.

The function of damping current is to reduce oscillations or ringing in a circuit by dissipating excess energy. It helps stabilize the system and prevent it from overshooting or oscillating uncontrollably. Damping currents are often used in applications like electrical circuits, mechanical systems, and control systems to improve system response and stability.

Heating an oxygen tank can cause the pressure inside the tank to increase, potentially leading to an explosion if the tank cannot withstand the pressure. This is because the heat can cause the oxygen molecules to move faster and collide more frequently with the walls of the tank, increasing the pressure. It is extremely dangerous to heat an oxygen tank and should never be done.

Metric unit of mass is Kilogram and that of weight is Newton.

Hope I am not wrong You are not wrong. A Newton is a unit of FORCE and weight is the force of gravity acting upon a mass. Mass is the quantity of matter in something. Gravity acts upon a mass and the force of gravity acting upon it is called it's weight. Why make a distinction you may ask? Because the force of gravity is different in different places on our planet. The weight of a mass on the moon would be a lot less than it's weight on earth because gravity on the moon pulls down with a lot less force than gravity on our earth. This concept is very important to scientists and Physicists and Engineers, when they make calculations.

Yes, the angel of refraction does depend on the wavelength of the light passing through a medium. This is known as dispersion, where different wavelengths of light are bent at different angles as they pass through a medium, causing them to separate.

Yes, a rose dipped in liquid nitrogen will eventually thaw as it absorbs heat from its surroundings and warms up. The process will depend on the temperature of the surrounding environment, but the rose will return to its natural state once the liquid nitrogen evaporates.

5 * 10**-12 mol

32 * 10**-9 mol

Concentration (M) * Volume (L) = mols

C1*V1=C2*V2

(5*10**-12)*V1=(32*10**-9)*V2

(5*10**-12)*V1/(32*10**-9)=V2

(5*10**-3)*V1/32=V2

The volume of the 5 picomolar solution that you wish take = V1

The volume of the 32 nanomolar solution that you need to make V1 at 5pM concentration = V2

Take V2, and place into graduated cylinder and fill to V1.

Distilled water freezes at 0°C (32°F), just like normal tap water. However, because distilled water lacks impurities and minerals present in tap water, it may freeze slightly faster. This is due to the absence of impurities that can act as nucleation sites for ice crystal formation.

No. Vitamin C and other vitamins will not substitute for birth control.

The physical appearance of an organism, known as its phenotype, is influenced by its genetic makeup (genotype). Genes contain instructions for producing proteins that determine traits like eye color, height, and hair texture. Variations in genes lead to the diversity in phenotypes seen across different organisms.
