When an El Niño occurs, there is less wind in an area. This results in less upwelling, which in turn does not bring nutrient-rich, cold water to the surface. This has a negative impact on people who make their living from fishing. Lesson 2.12 Question 1 options: True False
When an El Niño occurs, there is less wind in an area. This results in less upwelling, which in turn does not bring nutrient-rich, cold water to the surface. This has a negative impact on people who make their living from fishing. This statement is true.
What happens when El Niño occurs?El Nio occurs when surface water in the equatorial Pacific warms above average and east winds blow weaker than usual. La Nia is the opposite condition. The water is cooler than usual during this phase of ENSO, and the east winds are stronger. El Nios occur every 3 to 5 years on average.
Trade winds weaken during El Nio. Warm water is pushed back east, toward the Americas' west coast.
During El Nio, the upwelling of cooler oceanic water along the South American coast decreases. The trade winds typically move from South America to Asia/Australia, dragging warm surface water away from the coast while colder, nutrient-rich water rises to shallow depths.
Thus, This has a negative impact on people who make their living from fishing. This statement is true.

Hello everybody! Can somebody help me please with these two questions? ( I don't know if it's really chemistry if not sorry! )
Answer:
1. C
2. B
Explanation:
1. Most living things need oxygen, water, and food to grow. ... Other living things eat plants or other animals for food. The cells of living things divide, allowing the living things to grow bigger and to change as they grow. The cells divide to form new cells that are different from the original cells.
2. The usual method of prokaryote cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicate and original chromosomes are separated.

Identify the forces acting on you when you are standing still. Explain why the forces do not cause you to move.
Answer:
When you are standing still, you are exerting gravitational force on the ground. The downward gravitational force is balanced by the normal reaction force acting upwards. Also, since you are not moving the resultant of all forces is zero. Since the resultant force is zero, then according to Newton's 1st law, there is no change in the state of rest.

What is another name for fiber?
Answer: Thread, strand, tendril and filament are all synonyms of fiber.
Explanation: Fiber is a thread from a vegetable tissue, mineral substance, or textile is formed. It's also a dietary material that contains cellulose, lignin, and pectin.
Let me know if you have any questions.
~ Lily, from Brainly.
There are many other names for fiber. Some of them are Carbohydrate, Non-starch polysaccharide, Dietary fiber, Crude fiber, Insoluble fiber, Soluble fiber, Resistant starch, Prebiotic fiber, and Functional fiber.
Fiber is a type of carbohydrate that the body cannot digest. It is found in plant foods, such as fruits, vegetables, grains, and legumes. Fiber is important for gut health, heart health, and weight management.
The different names for fiber reflect its different properties and functions.
For example, carbohydrate is the general term for all sugars, starches, and fiber.Non-starch polysaccharide is a more specific term for fiber that is not made up of starch.Dietary fiber is the term used to refer to all the fiber that is found in food. Crude fiber is a measure of the total amount of fiber in food, including both soluble and insoluble fiber.Insoluble fiber is the type of fiber that does not dissolve in water. Soluble fiber is the type of fiber that dissolves in water.Resistant starch is a type of starch that is resistant to digestion.Prebiotic fiber is a type of fiber that feeds the beneficial bacteria in the gut.Functional fiber is a type of fiber that has been shown to have health benefits beyond its basic function as a food source.Therefore carbohydrate, non-starch polysaccharide, dietary fiber, crude fiber, insoluble fiber, soluble fiber, resistant starch, prebiotic fiber, and functional fiber are just a few of the names given to fibers.

Celestial bodies emit different types of radiation, only some of which can be detected by traditional telescopes. Radio waves are invisible rays that can be detected only by radio telescopes. A radio telescope functions like a television antenna. Radio waves from space are sensed by a gigantic parabolic reflector, which concentrates them toward the top of a focusing antenna. A radio receptor converts the radio waves into electrical signals which are amplified and then transmitted to the center of the parabola. They are then recorded and analyzed in the laboratory so that scientists can obtain a radio image of the source observed. The parabolic antenna can usually be oriented to detect radio waves from all directions of space. Some radio telescopes are fixed. The largest radio telescope in the world, located in Arecibo, Puerto Rico, is fixed. Built in a natural valley shaped like a giant parabola, its reflector measures 305 meters in diameter. Mobile detectors suspended from cables permit the scanning of one of part of the sky. Unlike traditional telescopes, radio telescopes can be used both day and night, even when there is cloud cover.
Electromagnetic waves can carry more data at higher frequencies. Why would a scientist opt to transmit data at a lower frequency instead?
What are the limitations of sending information using electromagnetic waves?
What are the differences between analog and digital signals?
What are the advantages of using digital signals over analog signals?
Using reliable internet sources, identify three ways we use analog and digital signals in our everyday lives.
Answer:1)The reason as to why scientists opt to transmit data at lower frequency instead of electromagnetic even if it can carry more data at a higher frequencies is because using higher frequencies of electromagnetic spectrum travel shorter distances but have higher data carrying capacity.So this physical characteristic of electromagnetic waves limits the range and availability of frequencies for sending information.
2) Limitations of using electromagnetic waves in sending communication
communication is a process of transmitting and receiving information in the form of signals.high technology communication use electromagnetic waves,there are various types of electromagnetic waves which are used in communication which include radio-waves,microwaves,infrared e.t.c some of their limitations are
i)Because there is limited number of broadcast frequencies the use of transmitters must be restricted in some way or they will seriously interfere with each other.
ii)Through the air signals can be distorted by atmospheric conditions and signals from space are sometimes distorted by solar activity
iii)physical activities such as mountains and buildings can prevent or interfere with some transmissions
iv)Through the air signals are not private,so any tuned receiver within the range can pick up them.
3)Differences between digital and analogue signals
Analogue and digital signal are used to transmit information usually through electric signals.
An analogue signal is continuous wave denoted by sine wave and may varry in signal strength (amplitude) or frequency(time) an example is sound from human voice is analogue because waves are continuous..
A digital signal is a signal in which the original information is converted into a string of bits before being transmitted .example a must for computer processing where is described as using (0s and 1s)and therefore can not take any fractional value.
4)Advantages of using digital signals over analogue signals
one advantage of digital signals are inherently less susceptible than analog signals to interference caused by noise because with digital signal it is not necessary to evaluate precise amplitude,frequency or phase.
Another advantage based in capacity is that digital signals carry more information per second than analogue signals.
Digital signals maintain their quality over long distances better than analogue signals.
5)How we use digital and analogue signals in our everyday live
digital signal processing is the way of life of current generation
example is mobile phones do alot of digital signal processing .they process our our speech digitally to remove background noise,echo e.t.c
Television also do a lot of digital processing of video,audio signal to present them in a better way.
How radio telescopes are used to explore space
A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky in radio astronomy.It has several main parts, a dish and antenna,a receiver,a detector and an analyzer.The dish collects the radio signals from space ad focuses them on the antenna.
6)How radio waves are used on earth
Radio waves are used to transmit television and radio programs They have longer wave lengths and are reflected by the ionosphere
7) Reasons why telescopes convert radio waves (analog) to electrical(digital) signals for analysis
This is because signals can be easily stored and transmitted in digital form.The analog is continuous in time and it is necessary to convert this to a flow of digital values.
