What Chaaracteristics coyuld You use to help you decide if a plant is a manocot or a dicot?

Dicots are woody, monocots are not. Dicots have two cotyledons, monocots have one. The flower petals group differently. Dicots have a three hole depression on their seeds, monocots have one. There are a few more differences that you can look up.

Is mansanitas fruit juice or extract used in making bioethanol?

Yes, the juice or extract of mansanitas fruit can be used as a feedstock for bioethanol production due to its high sugar content. The sugars can be fermented into ethanol by yeast, a process commonly used in bioethanol production.

Do you drill for petroleum?

Lots of companies drill for petroleum, It's one of the biggest industries in the world.

What are proteomic tools and their applications?

proteomics tools are basically used for protein structure determination and analysis.

proteomic tools includes, mass spectometry, NMR, terminater and traitor technology, quadrupole analyzer, MALDI-TOF.

What is a good hypothesis for soap to dissolve in water?

A good hypothesis could be: "I hypothesize that soap will dissolve in water because the hydrophilic (water-attracting) part of the soap molecule will interact with the water molecules, leading to the breakdown of the soap into its components."

How do you make a best out of waste science project?

There are many items that can be used to make a best out of waste science project. One could turn a CD into a clock, make a chime out of old keys, or make a pencil container out of old toilet rolls.

What happens to gases when you heat them up?

When you heat a gas, the energy you supplied is converted into the gas molecule becoming more energetic (obviously) and will bounce against its fellows more vigorously, and if free to do so, all the molecules will expand the volume they occupy.....

Added:

..... and / or pressure increases.

Cone shaped mountains that spew out lava or gas?

These mountains are likely volcanoes, with the conical shape formed by layers of hardened lava and volcanic ash. The lava and gas are released during volcanic eruptions, which occur when pressure builds up beneath the Earth's surface and forces magma to the surface. Eruptions can vary in intensity and can have significant impacts on the surrounding environment.

Do observations or inferences involve interpretation?

Observations involve direct sensory perception of something happening or existing, while inferences involve drawing conclusions or making interpretations based on observations and prior knowledge. Inferences require interpretation as they involve connecting information to form a logical explanation or hypothesis.

How can moving water on earths surface do work?

Moving water on Earth's surface can do work through hydroelectric power generation. The kinetic energy of flowing water is converted into electricity by turbines connected to generators. This renewable energy source is harnessed to produce electricity for various applications.

Is a tissue a organized group of cells?

Tissue is a group of similar cells that preform a common function.

Hope that helps :)

What happens when a solid a liquid and gas when it changes its state?

When a solid changes to a liquid, it melts and gains more kinetic energy. When a liquid changes to a gas, it evaporates and gains even more kinetic energy. When a solid changes directly to a gas without passing through the liquid state, it is known as sublimation.

What kinds of rocks form most of the crust of the earth?

The majority of Earth's crust is composed of igneous rocks, particularly basalt and granite. These rocks form through the cooling and solidification of molten material from beneath the Earth's surface.

Hurricanes eventually move back out to sea and blow themselves out?

Hurricanes can weaken and dissipate over time due to factors like encountering cooler waters or wind shear. As they move over land, they lose the warm ocean water that fuels their intensity. The friction from the land surface can also disrupt the storm's structure and cause it to break apart.

What is the conclusion of a magnet?

A magnet is an object that produces a magnetic field and attracts materials containing iron, nickel, or cobalt. Magnets have two poles, north and south, which attract or repel each other depending on their orientation. The magnetic force between the poles is strongest at the ends of the magnet.

What is the difference between accessory pigments and chlorophyll?

Carotenoids are mostly yellow-red-orange-brown in colour, chlorophyll is green. Carotenoids serve two main purposes in plants - protection from exces sunlight (a bit like sun-screen), and they can absord some sunlight which they then transfer to chlorophyll. Chlorophyll absords sunlight and is involved in photosynthesis.

Where does the energy that reaches the earth's surface come from?

The energy that reaches the Earth's surface mainly comes from the Sun in the form of solar radiation. This energy is essential for supporting life on Earth by driving weather patterns, ocean currents, and the photosynthesis process in plants. Some energy also comes from geothermal sources within the Earth's core.

What factors contributed to the Great war?

The main factors that contributed to the outbreak of the Great War (World War I) were militarism, imperialism, nationalism, and alliances. The assassination of Archduke Franz Ferdinand of Austria in 1914 served as the spark that ignited the conflict among the major European powers.

What is a hardened layer of magma called?

A hardened layer of magma is called a lava flow or volcanic rock.

Which layer of earth is like the shell of an egg?

The "Crust" is one of the Earth's layer.It can be compared to an eggshell

What the materials you need for the question does color affect the rate in which ice cubes melt?

For the question "Does color affect the rate at which ice cubes melt?", the materials you would need include several ice cubes of different colors, a timer, a tray to hold the ice cubes, and a controlled environment with constant temperature. By observing and timing the melting of ice cubes of different colors placed in the same conditions, you can compare the rates at which they melt to determine if color affects the melting rate.

Where could the organisms have come from in the 1768 broth experiment described?

the organisms could come from the heat in the broth if you boil it,cause if you boil it,it creates organisms. It will only work if you put a cap on top of the bottle you are boiling. the one with the cap on is not cantaminated. The one without the cap is cantaminated and already has organisms in it.so the organisms come from the oxygen in the one where it does not have the cap on

List two Geothermal energy uses from a volcano?

  1. Geothermal power generation: The heat from a volcano can be harnessed to generate electricity through geothermal power plants, which convert the natural steam and hot water from the underground reservoirs into usable energy.
  2. Geothermal heating: Heat from a volcano can be utilized for direct heating applications, such as heating buildings, greenhouses, spas, and swimming pools through geothermal heat pumps or district heating systems.

What is the chemistry related careers involved in developing a better breed of paddy?

Careers in developing a better breed of paddy may include agricultural chemists who study the chemical composition of soil and water, plant biochemists who investigate the metabolic pathways in plants, and biotechnologists who genetically modify crops for desired traits. These professionals work together to improve the nutritional content, disease resistance, and overall yield of paddy crops through chemical research and innovation.
