What are the two basic categories of reproduction?

Sexual and Asexual. Sexual reproduction requires that two cells (sperm and egg) unite to produce the first cell of the new organism. Asexual reproduction is a single organism that can reproduce without the aid of another.

1 watt hour equals how many watts?

1 watt-hour equals 1 watt times 1 hour, or 3600 joules.

What is a Pluto Platter?

A Pluto Platter is an early version of the Frisbee that was first introduced by the Wham-O toy company in the 1950s. It was later rebranded as the Frisbee due to its popularity and resemblance to a flying saucer.

What is the component tht have Rf value is 0.56?

It is difficult to identify a specific component based solely on an Rf value of 0.56, as Rf values can vary depending on the specific conditions of the experiment, such as the mobile phase composition and stationary phase used. More information about the experimental setup or characteristics of the component would be needed to make a more accurate identification.

How many watts does a cablebox use?

-21-inch Standard TV: 74 watts -42-inch LCD TV: 195 watts -DVD Player: 15 watts -VHS Player: 17 watts -Blu-Ray: 19 watts -Satellite Decoder: 35 watts -Converter Box: 08 watts -Cable Box: 25 watts -42-inch LCD TV: 195 watts -26-inch CRT TV: 74 watts

IS 100 watt amp big enough to play shows?

It depends on the size of the venue and the type of music being played. A 100 watt amp could be sufficient for small to medium-sized venues, especially if it is mic'd through a PA system. For larger venues or louder genres of music, a more powerful amp may be needed.

How many volts come out of an Australian power point?

As of 2000, Australian power points supply AC 230v at 50hz. Pre-2000, it was 240v at 50hz.

Why do i have black marks on wall above gas fire?

Black marks above a gas fire could be due to soot buildup from incomplete combustion. Ensure that the gas fireplace is properly ventilated and that the burner and logs are clean. It's also important to have the fireplace inspected regularly by a professional to prevent any potential fire hazards.

How do you convert a volt into a watt?

Volts are an electrical measure of potential difference and Watts are a measure of power.

The high school physics way of calculating the power (P) in watts, would be to multiply the given current (I) by the voltage (v).

P = V * I

From Ohms Law we know that V = I * R,

where R is the resistance of the electrical circuit given in Ohms, so we could also state that

P = (I * R) * I = I2 * R

So you have two equations there that should be useful.

Two major components of any computer system are its?

Some major components of a computer system are the following:

  • The CPU
  • The arithmetic unit
  • Memory
  • The processor
  • Input
  • Output
  • Hardware
  • Software

(Some of these overlap. For instance, a CPU is a processor, and is also part of the hardware of a computer.)

What are the principal parts of the cell?

The principal parts of a cell include the cell membrane, cytoplasm, nucleus, and organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. Each part carries out specific functions that contribute to the overall survival and functioning of the cell.

Is electronic laboratories a scam?

If you are talking about the "work from home" company in Georgia I have to say "YES". They have our money and a working, completed board that my husband assembled and we have heard nothing from them in over a month. The 2 email addresses I found for them from their web site both came back undeliverable. No phone numbers were given on any of the written correspondence we received BEFORE we sent our money. I am in the process of filing a complaint with the Post Office for mail fraud.

Latest model of computer?

The latest model of computer can vary depending on the brand and type of computer. As of now, some of the latest models include the Apple MacBook Pro with M1 chip, the Dell XPS 13, and the Microsoft Surface Laptop 4. These models are known for their powerful performance, sleek design, and advanced features.

Can you connect logitech x-540 to a TV?

Yes, you can connect the Logitech X-540 speakers to a TV using an RCA audio output or a headphone jack on the TV. Use an RCA-to-3.5mm adapter or cable to connect the TV to the 3.5mm input on the X-540 control pod for audio output.

What power socket do they use in Dubai?

In Dubai, the power sockets typically used are Type G, which have three rectangular pins in a triangular configuration. The standard voltage in Dubai is 220-240V and the standard frequency is 50Hz. It is advisable to bring a universal adapter if your plugs are not compatible with Type G sockets.

What is the supply voltage in us?

It's difficult to figure out exactly what your question is referring to...so I'll cover as many bases as I can.In the United States, the Electrical grid is delivered to consumers in the form of AC 110 - 125 volts, and runs at 60 Hz (cycles per second). Compare this to Europe which runs at 220 volts at 50 Hz. The actual voltage will very from time to time depending on customer demand, utility supply, and a number of other factors which are essentially out of our control. however, the 60 Hz SHOULD stay the same all the time.Inside the computer, the power supply uses a transformer to exchange voltage for amperes, reducing the voltage to about 12 volts, converts the AC to DC with a rectifier bridge, and store the resulting DC into a capacitor to smooth the flow out a bit. the power supply then breaks the power up into 12V, 5V, -5V, and -12V. If the motherboard in the computer needs other voltages (3.3v, 1.7v, etc), then the motherboard must reduce the voltage further itself).I hope this is what you needed.

What safety precautions should you take when carrying out food tests?

When doing food tests, you need to take proper safety precautions, including having a sanitary work space. Make sure the work area including the floor is clear, keep hair back, and use tongs for heated test tubes.

A network of canals that is covered with ribosomes is called what?

The network of canals that is covered with ribosomes is known as the rough endoplasmic reticulum. The ribosomes on the rough endoplasmic reticulum are involved in protein synthesis.

What would be a typical joules rating for a surge suppressor designed for home use?

Destructive surges can be hundreds of thousands of joules. A protector rated for hundreds of joules does not claim to protect from the other and typically destructive surge. In fact, a 250 joule surge will simply be converted by electronics into low voltage DC to safely power its semiconductors.

A destructive surge may be 20,000 amps. So a minimal 'whole house' protector for all homes should be at least 50,000 amps. Any protector that fails on a surge did not provide effective protection. And was a potential house fire.

What are communication mediums?

Communication mediums are the tools or methods used to transmit information between individuals or groups. Examples include face-to-face conversations, written documents, emails, telephone calls, video conferences, social media, and more. Each medium has its own advantages and limitations in terms of speed, clarity, and richness of communication.

How are watt mega-watt giga-watt defined?

A megawatt is 1000 kilowatts (also equal to 1341 horse power) or 1*10^6 watts, a gigawatt is 1000 megawatts. A watt is equal to one joule per second and a joule is defined as the amount of work done when 1 ampre of electrical current is passed through 1 ohm of resistance. Ohm is defined as the amount of electrical resistance of a conductor in which 1 ampre of current is produced by a potential of 1 volt across its terminals.

Is there a difference between a 9-volt 200mA power cord and a 9-volt 2 amp power cord?

Yes, there is a difference. The 9-volt 2 amp power cord can handle a higher current flow compared to the 9-volt 200mA power cord. This means it can power devices that require a higher current draw without being damaged.

What are framing bits used for?

Framing bit is a common practice in telecommunication. Framing bit is a bit that precedes a T1 or J1 frame. It is used for the purpose of synchronization of the incoming data with the receiver.
