Lenny accidentally drops his matchbox car into a graduated cylinder. The car has a mass of 10 grams and the water level in the cylinder rises from 41 ml to 46 ml. Determine the density of the matchbox car. The formula for density is D =
m
v
.
A) 0.5 g/ml
B) 2 g/ml
C) 15 g/ml
D) 50 g/ml
Answer:
B) = 2 g/mL
Explanation:
Given data:
Mass of car = 10 g
Volume of water = 41 mL
Volume of water+ car = 46 mL
Density of car = ?
Solution:
Density is equal to the mass of object divided by volume of object.
Formula:
d = m/v
volume of car = Volume of water+ car - Volume of water
volume of car = 46 mL - 41 mL
volume of car = 5 mL
d = 10 g/ 5 mL
d = 2 g/mL
Is Protein a short term energy source or a long
term energy source?
Answer:
short term
Explanation:
Short-term response energy storage devices are usually applied to improve power quality, particularly to maintain the voltage stability in power systems, throughout a contribution during transients (few seconds or minutes) [4].
When do enzymes stop reacting to the substrates?
Answer:
If the reaction is divalent metal ion-dependent, you can stop the reaction by adding an excess of EDTA to bind the metal.
You can kill the protein by adding perchloric acid, then precipitate the perchlorate with an equivalent amount of potassium carbonate, leaving nothing but carbonic acid in the supernatant, which bubbles off as carbon dioxide. Centrifuge the sample and take the supernatant to analyze for the product.
A rather slow method is ultrafiltration, using a micro-centrifugal ultrafilter (e.g. Microcon) with a molecular weigh cutoff smaller than the molecular weight of the enzyme. This can be done at 4oC to slow down the reaction during the separation.

What is difference between unicellular and multicellular organisms?
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore, all cells have a cell wall but only plant cells have a cell membrane. The given statement is false.

What are three ways energy is used by the organisms?
Answer:
Organisms use energy to survive, grow, respond to stimuli, reproduce
Explanation:
Three ways energy is used by the organism are food, nutrients, and sunlight.
What are living organisms?Living organisms are those organisms that grow, adapt, and reproduce their young ones. Organisms need energy for their biological purposes. Organisms get energy from plants and other animals. This energy is used in the form of glucose.
Cellular functions require energy, which living things must obtain from food, nutrition, or sunshine. Energy is used in a cell for the transport, synthesis, and breakdown of nutrients and molecules.
Glucose and ATP are the two types of molecules that organisms primarily use for chemical energy. In the entire biological universe, both molecules are used as fuel.
Therefore, the energy is used by the organisms in three ways that are food, nutrients, and sunlight.

2. Which two biomes are known asthe dry biomes?
tundra and forest
desert and tundra
desert and grassland
Answer:
The desert and tundra biomes have very different temperatures as well as extremely different plants and animals. The desert can get very hot during the day, but cool off quickly at night. It has sandy soil and supports very little plant life. Animals found in the desert include lizards, javelinas, Gila monsters, coyotes, bobcats, scorpions, and kangaroo rats. The tundra is cold, dry, and often dark. The average temperature is about 10°F. The soil below the surface is permanently frozen, and is called permafrost. A few types of plants grow during the short summer season. Animals found in the tundra include caribou, foxes, wolves, and Arctic hares.

What do scientists do when experiments are not possible
Answer:
Well, to be honest I think that they might just figure out another way to do that experiment.
Explanation: My reasoning is, that if an experiment isn't possible due to complications like maybe it could be to dangours or it could have reaction that they don't know about. So if they aren't able to do an experiment then they might find a safer one to do or they might just skip it and research more about it and see how it would react to certan things.
