Plants make glucose during photosynthesis. Some of the glucose is changed into insoluble
starch.
What happens to this starch?
Answer:
need thanks
Explanation:
starch is also a form of glucose
it is formed from CARBON DIOXIDE SUNLIGHT AND DI HYDROGEN OXIDE(WATER)
it will be used to prepare food for plants
Answer:
Some glucose is used for respiration , while some is converted into insoluble starch for storage. The stored starch can later be turned back into glucose and used in respiration.

Answer:
B. From 200 m to the surface
Explanation:
Photosynthesis is a process which is light-dependent. Therefore, regions where light availability is not sufficient or event absent will not support photosynthesis.
In the oceans, light availability decreases with increasing depth. Below, a certain depth in the ocean, light availability becomes insufficient to support photosynthesis and this is usually below 200 m. The uppermost region of the ocean from 200 m to the surface of the ocean is sufficiently illuminated to permit photosynthesis by phytoplankton and plants. This region is called the euphotic zone.
Therefore, from the attached image, the correct option is B, since it represents the euphotic zone of the ocean.
Protein molecules are the building blocks of the body. They are made up of long chains of amino acids. Draw the general structure of an amino acid.
Answer:
Please find the diagram of the general structure of amino acids attached.
Explanation:
Proteins are one of the four major biomolecules in living systems. As rightly stated in this question, they are building blocks of the body. However, proteins are biological polymers made up of monomeric units called AMINO ACIDS. A long chain of these amino acids make up a protein molecule.
An amino acid generally consists of a central carbon atom called ALPHA CARBON, attached to an amine group (-NH2), a carboxylic acid group (-COOH), and a side chain (R side chain). All 20 amino acids that exists in nature have this general structure but differs only in the type of SIDE CHAIN (R group) they possess i.e. all amino acids have a different R side chain.
Please find the diagrammatic representation of the general structure of amino acids as an attachment.

Please help me finding an information: why there is life on Earth
Answer:
It seems possible that the origin of life on the Earth's surface could have been first prevented by an enormous flux of impacting comets and asteroids, then a much less intense rain of comets may have deposited the very materials that allowed life to form some 3.5 - 3.8 billion years ago.

I hateeee science
Answer:
Advantages:Solar:does not pollute,Renewable energy
Disadvantages:Expensive,Uses a lot of space
Disadvantages Wind:The wind is inconsistent,May reduce the local bird population
Advantages:unlimited, free, renewable resource
Biofuels Advantages:Cost-Benefit.
Disadvantage:Monoculture. Use of Fertilizers.
Nuclear fusion disadvantages:Scaling down the sun
Advantages:potential advantages of nuclear fusion energy are manifold, as it represents a long-term, sustainable, economic and safe energy source for electricity generation.
Fuel Cells:Advantages: Hydrogen fuel cells emit only water, so there are no carbon dioxide emissions and no air pollutants that create smog and cause health problems at the point of operation.
Disadvantages:fuel cells and electric motors are less durable than petrol engines and diesel engines, so they are not so long-lasting
Wave Power Advantages:Suitable to Certain Locations. The biggest disadvantage to getting your energy from the waves is location.
Effect on Marine Ecosystem
advantages:the energy is renewable
Geothermal Advantages:Environmentally Friendly. Geothermal energy is more environmentally friendly than conventional fuel sources such as coal and other fossil fuels.
Renewable.
disadvantages:Environmental issues. There is an abundance of greenhouse gases below the surface of the earth.
Coal disadvantage:The major disadvantage of coal is its negative impact on the environment.
Advantage:oal is easy to burn.Coal produces high energy upon combustion.
Oil :Advantages:Oil has High Energy Density. Oil is Easily Available.
Disagavantege:Oil is a non-renewable source of energy. Burning oil produces carbon dioxide gas
Natural Gases disadvantages:Gas is highly flammable, which means leaks can result in explosions.Natural gas is toxic.
Advantages:Natural gas is environmentally friendly because it burns cleaner than other fossil fuels.
Explanation:
transcribe and translate dna
Answer:
The human genome contains around 30 000 genes, each of which codes for one protein. Large stretches of DNA in the human genome are transcribed but do not code for proteins. ... The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
Explanation:
Compare and contrast how genetic information is passed in sexual and asexual reproduction. Science
Asexual Both. Sexual
Uniform. Offspring. Diverse
Indentical Trait. Different
Budding Type of reproduction. 2 parents
1 parent Flowers
What statement best explains how the traits of an organism are determined by the DNA in each of their cells? Answer F DNA is translated into a strand of mRNA, which is used to control cellular functions G The information from DNA is used to determine the amino acid sequence of proteins H The hydrogen bonds of DNA are broken to provide the energy for protein synthesis. J The DNA double helix is unzipped, and each strand codes for a single protein.
Answer:
The information from DNA is used to determine the amino acid sequence of proteins
Explanation:
DNA is the genetic material of living organisms, which serves as a storage molecule for the genetic information needed to synthesize useful products (proteins). The information in the DNA, however, must undergo GENE EXPRESSION in order to be decoded.
The process of gene expression involves two major processes viz: transcription and translation. Transcription is the process by which DNA is used as a template to synthesize mRNA molecule while Translation is the process by which mRNA is used to synthesize amino acids, building blocks of proteins. Hence, the information from DNA is used to determine the amino acid sequence of proteins.

Oxygen molecules are small enough to fit through the phospholipid bi-layer, they do
this through what process?
Answer:
I think it's Simple Diffusion
Explanation:
Simple Diffusion Across the Cell (Plasma) Membrane: The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.

If a stationary front does not move much, what kind of weather can you expect in your area?
Answer:
A stationary front forms when a cold front or warm front stops moving. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
Explanation:

What medium does sound waves travel the fastest
In (solid, liquid, or gas) why？
Answer:
Sound travels fastest in solids and slowest in air. Water is in between. This is because the particles in solids are closer together than the particles in liquids or gases, and the particles in liquids are closer together than the particles in gases. The tighter particles are packed in a space, they collide more frequently. This allows sound, which is simply the combined collisions of particles, to travel fastest in solids. So, to reiterate, sound travels fastest in solids, then water, and slowest in air.
