Explain how density and matter are connected.


Answer 1
Answer: Density and matter are connected by their very definitions.

Density is defined as the amount of mass per unit volume.  Basically, density is the amount of matter present in a certain volume of space.  The more matter and the smaller the volume of space, the higher the density.  Higher density pretty much means more matter squished into the same amount of space.

What type of UV light is used in tanning beds, and why is it so dangerous?


The type of UV light used in tanning beds is UVA rays also known as tanning rays. These rays are so harmful because they are not absorbed by the ozone.

What do you mean by UV light?

UV light may be defined as electromagnetic radiation or light having a wavelength greater than 100 nm but less than 400 nm.

Tanning rays are so dangerous because they cause skin cancer. So, exposure to these UV lights on the skin is so harmful and deadly.

Therefore, the type of UV light used in tanning beds is UVA rays also known as tanning rays.

To learn more about Tanning rays, refer to the link:

UV radiation (Sunlamps)

These are so dangerous because they cause skin cancer. Not only is it skin cancer, it is the deadliest form of it. Exposure to radiation is horrible for you.

Is a class of diseases characterized by the uncontrolled division of cells?


The correct answer is "cancer"

Cancer is a class of diseases characterized by uncontrolled division of abnormal cells. The hallmark of cancer is dysplastic growth of cells that is resistant to apoptosis therefore the dysplastic growth of cells will eventually go into a tumorous growth consisting of abnormal cells and will eventually be vascularized and produce metastasis in other organs.

The enzymatic breakdown of any type of food molecule is called ________. A. diffusion
B. active transport
C. hydrolysis
D. denatured


Hydrolysis occurs in the presence of enzymes (organic compounds that generally increase the rate of chemical reactions) called hydrolases.

What is the hydrolysis?

It is a basic process of digestion and consists of the addition of water molecules to polysaccharide, fat or protein by specific enzymes that convert it into glucose, fatty acid and amino acid, respectively.

Characteristics of hydrolysis

  • It consists of the conversion of large nutrient molecules into small ones that are possible to absorb.

Therefore, we can conclude that digestion consists of hydrolysis, a water molecule is introduced to break bonds in large molecules by the action of specific enzymes.

Days 4-10 of the decomposition process is called the _____ stage.


Putrefaction. It has Latin origins and putre means to rot, rotten.

In this stage tissues and cells start breaking down, and that is what characterizes this stage the most.

Which product is missing from all of the products that are made after the electron transport chain of aerobic respiration? Glucose + Oxygen → Carbon Dioxide + Water + _________ Energy








All living organisms require energy for their life processes. The way they obtain this energy is via the process of cellular respiration. Cellular respiration is the metabolic (catabolic) reaction in which cells break down food molecules to release energy by combining glucose and oxygen. Cellular respiration can either be aerobic (with oxygen) or anaerobic (without oxygen). Aerobic cellular respiration involves three main stages viz: Glycolysis, Kreb's cycle and Oxidative phosphorylation.

The Oxidative phosphorylation of aerobic respiration further includes the Electron transport chain (ETC), which is a series of electron transfer in order to build a pump that will facilitate the synthesis of ATP (energy molecule). In a nutshell, after the ETC, 38 and 36 molecules of ATP are produced in prokaryotes and eukaryotes respectively.

The overall equation of aerobic cellular respiration is:

C6H12O6 + 602 ------> 6CO2 + 6H2O + ATP (energy)

Energy is the answer.

What occurs in the non living part of the water cycle?


Pathways through which nitrogen is recycled through the biosphere. Water that falls from clouds in the atmosphere to Earth's surface, such as rain, snow, and sleet. Precipitation that is not absorbed by the soil and flows over the surface of the ground. Process in which plants give off water vapor.
seeps in the ground and becomes ground water. Water is taken by roots of plants after going through plants the water moves in the atmosphere. ... in the living portion of the water cycle, water is taken up by.

The terms foliated and nonfoliated describe the _____ of a metamorphic rock. A. texture
B. location
C. chemistry
D. heat and pressure


I believe it's texture. Because foilated and nonfoilated are terms that describes the tecture of metamorphic rocks, with that being said. It's texture.
