Look at the chart below to answer this question. Which substance is the LEAST dense of the three substances?
Substance A
Substance B
Substance C
Answers
Answer:
Substance B
Explaination: Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.

Astronauts need to take water to take on the moon so that the plants could grow in a lunar plant growth chamber.
What affects lunar plant growth chamber?Plants can be grown in the lunar regolith. Plants grown on the moon were not as robust as the plants which are grown in soil of the Earth, or even as those in the control group grown in a lunar simulant made from the volcanic ash, however they did indeed grow well.
Real lunar and the Martian regolith seem to contain all the essential ingredients which are required for the growth of plant. However, there is a very small amount of reactive nitrogen and growing food materials in it that requires a large amount of water. Regolith can only store up to thirty percent of the water which organic soil of the Earth can store.

La influencia que tiene la temperatura en la reproducción de los paramecios, en muestras de agua estancada
Answers
Answer:
Para un paramecio la temperatura óptima requerida para llevar a cabo sus funciones metabólicas (incluida la reproducción) se encuentra entre 24 °C y 28 °C
Explanation:
Los paramecios (género Paramecium) son protozoarios, es decir, organismos microscópicos del reino protista. Un paramecio es un organismo unicelular que puede llevar a cabo todas las funciones esenciales de un modo funcionalmente similar a una célula animal. Los paramecios pueden reproducirse tanto de manera sexual como asexual (bipartición). Estos organismos viven en cuerpos de agua dulce rica en nutrientes orgánicos como estanques, charcos, regiones de ríos parcialmente estancadas, etc. En estos ambientes los paramecios se reproducen de un modo óptimo a una temperatura entre 24 °C y 28 °C, donde pueden llegar a dividirse hasta 4 veces al día.

Why do hydrogen atoms form a molecule but helium atoms do not?
Answers
Answer:
Explanation:
In terms of old school electron shells - One Hydrogen atom on it's own has an empty shell, and therefore to fill the shell it needs another electron. In the case of Helium, it already has two electrons at the same energy level - so it cannot accept any new electrons i.e. it cannot form new bonds.
Answer:
Hydrogen atoms can form a molecule as 2 hydrogen atoms together can result in a low energy combination of 2 electrons of the same energy level.
Explanation: Helium atoms already have 2 electrons of the same energy so therefore it cannot accept more.

Describe an adaptation to a plant's life cycle and explain how this adaptation helps the plant survive. Source StylesNormal
Answers
Answer:
The adaptation of a plant in an environment ( for example,desert) depends on the structural parts of the plant which enables it to complete it's life cycle.
Explanation:
Plants are found in different types of environment. They need to possess and show some features that will enable them to live successfully and reproduce in that particular environment. Such features may be structural, functional or behavioural which are known as ADAPTATIONS.
Furthermore, in environment where there is scarcity of water supply, plants known as xerophytes can survive or thrive. They show the following adaptations:
--> well developed roots: the roots grow down to great depths if necessary and branch extensively in order to absorb water from as large an area as possible.
--> presence of swollen stems: These stems contains water storage cells which are called succulents. They help the plant withstand long period of drought.
--> Reduced leaves: This helps in reducing water loss from leaves through transpiration. For example in plants like the cacti, the leaves are reduced to spines.
Therefore, these structures helps the plant survive in its present environment.

What changes occur in taste receptors when the membrane is depolarized during receptor potential A. Voltage-gated Ca2 channels open, triggering the release of neurotransmitter. B. Voltage-gated Cl- channels open, triggering the release of neurotransmitter. C. Voltage-gated Ca2 channels open, inhibiting the release of neurotransmitter. D. Voltage-gated Cl- channels open, inhibiting the release of neurotransmitter.
Answers
Answer:
A. Voltage-gated Ca² channels open, triggering the release of neurotransmitters.
Explanation:
For taste mechanisms to function properly, it is necessary the activation of taste receptors.
Through the activation of taste receptors, transduction cascades occur, involving ion channels that are located in the apical or lateral membranes. There occurs a subsequent release of chemical neurotransmitters that send signals to the control centers.
Salty and sweet flavors produce the membrane depolarization that results in Ca+ ions´ entrance to the cell. Ca+ initiates the release of neurotransmitters. Afferent gustative neurons receive the message and send it to the control center, the encephalon. After that, gustative cells go back to the initial state, repolarizing.

*WRITE AS A CER*
Answers
Answer:
Read explanation
Explanation:
Surface C exerts the least amount of friction on the box. Evidence that proofs this claim is that the length of time it took the box to stop is greatest compared to surfaces A and B. The box and the amount of force added is the same for each surface test. It would take the box less time to come to a stop the more friction there is upon the surface. Surface A having the quickest stop time meaning it has the most friction and C having the most time showing that it has the least amount of friction. In conclusion, surface C exterts the least amount of friction on the box.
