NUCLEOTIDES.... is not a component of lipids..
Thanks..
Nucleotides are not a component of lipids.
WHAT ARE LIPIDS:
Lipids are one of the four biomolecules we have in nature. Structurally, lipids are made up of monomers called FATTY ACIDS and GLYCEROL. Each of these monomers are made up of long chains of carbon, meaning that lipids also have long chains of carbon.However, nucleotides are monomers of another biological molecule called nucleic acids and hence, cannot be a component of lipids.

explain how longitude lines were established
Answer: Eratosthenes was the first to propose a system of longitude between 260 - 201 B.C. Greek astronomer Hipparchus was the first to use longitude to define a location (along with latitude). Longitude lines run from the North and South Poles and are measured by one arcdegree. These lines are called meridians. Unlike latitude, longitude was not able to be determined until the 18th century as a result of difficulty. The Royal Observatory in Greenwich, England marks zero degrees longitude. Longitude was accepted after the 18th century after it was able to be determined and measured by mathematics.

A car is traveling 5 m/s North, its displacement is
after 9 seconds?
Given parameters:
Velocity of the car = 5m/s North
Time = 9s
Unknown:
Displacement of the car = ?
Solution:
Displacement is the distance traveled in a specific direction. It is a vector quantity with magnitude and direction.
To find displacement use the expression below;
Displacement = Velocity x Time
Input the parameters and solve;
Displacement = 5 x 9 = 45m due North
The displacement of the car is 45m due North

Which of the following is a MECHANICAL wave vibration? * O Sound waves O Light waves O Radio waves O Reflection
Answer:
An example of vibration by mechanical waves is sound waves.
Explanation:
Mechanical waves are those capable of transmitting energy, which can propagate in the same direction, resulting in an alteration of the mechanical properties of a material. As a result of this, the material presents changes in the energy of its atoms and molecules.
Sound waves are mechanical waves, which require a medium for transmission and act as elastic waves capable of propagating longitudinally, producing a vibration.
Sound propagates and can produce waves in water or vibrations that reach the eardrum and enable the reception of this sound.
The other options are not correct, because light and radio waves are electromagnetic waves that are transmitted in a vacuum, without producing vibrations. Reflection is a property of light.

what is active transport and what does it require?
Answer:
An active transport is the movement, requiring energy, of ions or molecules across a membrane into a region of higher concentration.
Memory technique:
To help you remember the difference between active and passive energy, think of being active, like playing football or jumping rope. All these things require energy, just like an active transport. Passive transport does NOT require energy.

Answer: the answer is D or can be interior
Explanation: because I took the test and I picked have Steep sides and it's wrong hi relief is wrong and high Evolation is wrong so in conclusion D is your answer
Hope this helps!
The phrase that describes a typical feature of plains is that it can be interior. Thus, the correct option for this question is D.
What do you mean by Plains?Plains may be defined as a type of landform that has a broad area of relatively flat land. These are one of the most common types of landforms on the earth's surface. They significantly cover more than one-third of the world's land area. Plains exist on every continent.
According to the context of this question, mountains are landforms that usually have a high relief and a high elevation. A canyon has steep sides along with narrow valleys. So, plains are the landforms that significantly have an interior and flat land.
Therefore, the phrase that describes a typical feature of plains is that it can be interior. Thus, the correct option for this question is D.

tridactyla
Pilosa Chordata
myrmecophaga Tridactyla
Myrmecophaga tridactyla
Answer:
Myrmecophaga tridactyla
Explanation:
This question involves the level of classification of the Giant anteater. The classification system ranks from kingdom to species. However, living organisms are named according to the BINOMIAL NOMENCLATURE. Binomial nomenclature is a system of naming living organisms as given by Carolus Linnaeus.
This binomial nomenclature, as the name implies, uses two Latin names; one which is the generic name of the organism and the other which is the specific name. Based on the principles that govern this naming system, the GENERIC name must begin with a capital letter while the specific name is written in small letters all through.
Following this principle of binomial nomenclature, the proper scientific name of the Giant anteater is as follows:
Generic name - Myrmecophaga
Specific name - tridactyla
Hence, the scientific name of the Giant ant eater is Myrmecophaga tridactyla.

This is NOT a part of the phosphorus cycle.
phosphate is absorbed from the soil by plants
atmospheric phosphate
phosphate in plants is eaten by animals
Phosphate is incorporated into sedimentary rocks
Answer:
Many plant crops need more phosphorus than is dissolved in the soil to grow optimally. In addition, crops are usually harvested and removed – leaving no decaying vegetation to replace phosphorus. Therefore, farmers replenish the phosphorus ‘pool’ by adding fertilisers or effluent to replace the phosphorus taken up by plants.
Explanation:
Atmospheric phosphate is NOT a part of the phosphorus cycle. thus, option B is correct.
What is the phosphorus cycle?The phosphorus cycle is a biogeochemical cycle that deals with the movement of phosphorus in the form of different compounds.
The soil absorbs the phosphate salt dissolved in water, although the amount of phosphorus present is relatively low.
Phosphorus is absorbed by the animal from plants or from plant-eating animals.
When plants and animals die, a microorganism decomposes them, which is then recycled into the soil and water. Soil and water end up in sediments and rocks, where they weather and release phosphorus.
