Jackson uses a battery operated toothbrush that is rechargeable. What happens when Jackson plugs his toothbrush into an electrical outlet to recharge it?
Answer:
Explanation:
The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use.
Thirty corn seedlings of equal size were randomly assigned to one of three treatment groups. At the beginning of the experiment, the plants in group I were dried and the mass was determined.
Answer:
The definition of the particular situation is outlined throughout the following section of the justification.
Explanation:
The query given seems to be incomplete. Please find the full issue attachment.
(a)
CO2 provides an inorganic component containing cellular mass. Throughout the atmosphere, plant species suck up CO2. Plants manufacture sugars throughout the mechanism of photosynthesis. Sugar is turned into glucose, cellulose as well as certain carbohydrates processed in cell walls. This raises the density of the plant. The process needs water, Carbon dioxide respectively.(b)
Sunlight is absorbed by chlorophyll as well as converted through chemical energy. The plant utilizes biochemical resources to synthesize sugars. The volume including its plant has risen due to the manufacture of sugars, respectively. For producing sugars, plants require light. The loss in mass has been caused by cellular respiration. There's this community of crops in the dark. They don't do photosynthesis, hence.Because to get power for something like the operations including its plant, individuals had to undergo respiration. So there is no photosynthesis, and therefore there is no sugar development. But instead to release energy, the sugar contained in the plant is eaten. And that's why the amount including its plants holding in darkness reduces.There are 3 steps given below for cellular respiration:
GlycolysisKreb's Cycle Electron Chain of TransportCellar respiration fills certain living things with energy.
⇒ [tex]C_6H_{12}O_6 + 6 O_2\rightarrow 6CO_2 + 6H_2O + (ATP) power.[/tex]
The generated CO2 has so far been delivered from the body including its plant. Therefore the plant mass was indeed decreased by this.

Which of the following statements about enzyme functions is true
What are found in both mitochondria and typical prokaryotic cells?
80S ribosomes and circular DNA
70S ribosomes and circular DNA
70S ribosomes only
circular DNA only
Answer:
B) 70S ribosomes and circular DNA
Explanation:
Remember: Mitochondria is found in the cytoplasm of almost all eukaryotic cells.
All prokaryotes have 70S ribosomes. Eukaryotes have 80S ribosomes, with some exceptions like mitochondria and chloroplast.
Circular DNA is DNA that forms a closed loop and carries genetic material. In both prokaryotes and eukaryotes, the chromosome represents circular DNA, although in eukaryotes, the chromosomes are more complex in structure.

Explanation:
Early scientists were confused by the Euglena because they wanted to classify all living things as either plants or animals. Why do you think the scientists were confused?
Answer:
Euglena perform photosynthesis through the presence of chloroplasts in their cells, but they are also able to feed like animals by consuming and digesting organic material. They have features of both an autotroph(an organisms that produces its own food, such as plants) and a heterotroph (an organism that can not produce its own food and instead need to consume organic matter). Due to having features associated with both plants and animals, this would cause confusion to the scientists at the time who struggled to classify them as either plant or animal.

Answer:
What sends oxygenated blood back to the heart from the lungs?
Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

Explanation: The spiders could destroy the ecosystem of a region where it had not been presented, since insects or some mammals are defenseless against this species because they had never seen or interacted with it, it can hunt and reproduce to a great extent, becoming a problem, and by taking flowers from another region totally different from yours (in animal and plant life) can cause serious damage, since these flowers could bring dangerous insects even for humans, and for native species, ending with what can eat.

Which statement correctly describes what proteins, lipids, and glycogen have in common
Answer:
They are all used as primary energy sources during exercise. They are each stored in the liver to be used as a ready energy reserve. They each can be broken down to provide ATP to cells.
Answer:
The statement that correctly describes what proteins, lipids, and glycogen have in common is C. they each can be broken down to provide ATP to cells. Proteins, lipids, and glycogen all consist of a group of molecules, which means they can be broken down to these smallest items. ATP, or adenosine triphosphate, is a molecule that can be found in anything, and which we need for everything because it is a source of energy in living beings.

HE SPRAYS THE OTHER HALF WITH WATER AFTER 3 DAYS OF THE TREATMENT THERE IS NO CHANGE IN THE APPEARANCE OF THE GREEN SLIME OR EITHER SIDE OF THE SHOWER.WHAT IS THE INDEPENDENT VARIAB LE
DEPENDENT VARIABLE
CONTROL GROUP
CONSTANT
Answer:
INDEPENDENT VARIABLE: COCONUT JUICE
DEPENDENT VARIABLE: APPEARANCE OF GREEN SLIME
CONTROL GROUP: THE SIDE OF THE SHOWER HE SPRAYED WITH WATER
CONSTANT: SAME TIME OF MEASUREMENT, SAME SHOWER
Explanation:
- Independent variable is the variable that is changed or manipulated by an experimenter. In this experiment, Homer sprays a side of his shower with COCONUT JUICE and the other side with water. This means that the independent variable is the COCONUT JUICE.
- Dependent variable is the variable that responds to the independent variable. It is the variable that is measured by the experimenter. In this experiment, the dependent variable is the APPEARANCE OF GREEN SLIME on the shower.
- Control group is the group in an experiment that does not receive the experimental treatment (coconut juice). This means that the control group of this experiment is the SIDE OF THE SHOWER HE SPRAYED WITH WATER.
- Constants or controlled variable are the variables in an experiment that are kept unchanged throughout the experiment. In this case, the constant is SAME TIME OF MEASUREMENT, SAME SHOWER.

O pump wastes.
O exchange O2 and CO2 gases.
filter wastes.
O transport O2 and CO2 gases.
Answer:
exchange O2 and CO2 gases.
Explanation:
The respiratory system's main function is to exchange oxygen and carbon dioxide gases within the body. The organs that make up the respiratory system include the nose, pharynx and larynx, the trachea, bronchi, and the lungs. Each of these organs help with the process of breathing and/or the exchanging of gases within them.

What is the approximate average yearly total snowfall gradient between locations A and B?
(1) 0.25 in/mi (2) 2.50 in/mi (3) 0.40 in/mi (4) 4.00 in/mi
Snowstorms that continue three hours or longer, have consistent wind speeds of at least 35 mph (about 56 km/h), and have visibility of less than a quarter mile are referred to be blizzards. Thus option C is correct.
What average yearly total snowfall gradient?The image demonstrates a snowfall gradient, or the variation in snowfall rates from one place to the next. Weather.com meteorologist Brian Donegan stated, “It may happen everywhere that gets snow showers and is fairly regular.”
For clouds and snow to form, there must be adequate moisture in the atmosphere. Snow cannot form if there is insufficient moisture. The atmosphere must continuously add moisture to the clouds in order for snow to continue to create and fall to the ground during heavier precipitation.
Therefore, 0.40 in/mi is the approximate average yearly total snowfall gradient between locations A and B.
