its called the Cuticle but that's on leaves not the plant its self

Yes, graphite is a relatively soft mineral with a hardness of 1-2 on the Mohs scale. This means it can be easily scratched by materials with a higher hardness, such as a fingernail, which typically has a hardness of around 2.5.

In electrical systems, positive (+) refers to the terminal with a higher voltage potential, usually designated for the flow of current into a component. Earth (or ground) serves as a reference point with a voltage of zero and provides a return path for current to complete the circuit safely.

Adding substances like water, clay, or sand to lava can help slow it down by cooling and solidifying it more quickly. Water can create a crust on the surface, while clay and sand can mix with the lava to thicken it and impede its flow.

Plasma proteins or blood proteins are various antibodies, clotting factors, albumin, globulin, fibrinogen and so on. In addition to proteins it has vitamins, ions, water, oxygen and CO2. Immunity and immune based process are carried out by these proteins.

Other chemicals that can act as catalysts for the luminol reaction include hemoglobin and horseradish peroxidase. These catalysts can enhance the chemiluminescence produced when luminol reacts with hydrogen peroxide in the presence of an appropriate metal ion.

he drew a table and decided to count the number of plants with each trait that turned up he thought it might help him to explain his results

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.

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.

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

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.

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."

expand, causing the air to become less dense and rise.

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.

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.

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.

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.

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

Hope that helps :)

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.

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 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.

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.

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.

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.
