What happens to the surface are as the cubes get larger?
Answers
Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.

A. they are both key components of plant cells.
B. they both produce chemical and electrical energy.
C. they are both key components of solar panels.
D. they both use energy from the sun to separate electrons from atoms.
Answers
Answer:
D. They both use energy from the sun to separate electrons from atoms.
Explanation:
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH.
Photovoltaic systems use the photons produced by sunlight to generate direct current (DC) electricity. When the photons hit the panel they are absorbed by the panel's semiconducting silicon material.

Tratando-se sobre atividades aeróbias, segundo Cooper (1972), qual das alternativas abaixo não está correta? a) Aumento da eficiência dos pulmões e coração. b) Aumento das cavidades do coração, aumento do volume total de sangue e volume máximo de oxigênio (aumento da absorção, captação e transporte de oxigênio). c) Aumento do número e tamanho dos vasos sanguíneos. d) Melhora da tonicidade muscular e dos vasos sanguíneos. e) Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL) URGENTE
Answers
Answer:
Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL)
Explanation.
Esto debe revertirse, debe ser una disminución del colesterol malo y un aumento del colesterol bueno.
Básicamente, el ejercicio aumenta el HDL y reduce los triglicéridos. En condiciones normales, los ejercicios aeróbicos no reducen el LDL. Sin embargo, cuando se combina con cambios en la dieta y una pérdida de peso bien controlada, el efecto combinado podría reducir el LDL.
En las condiciones estándar, el ejercicio recomendado por semana es de 150 minutos de ejercicios suaves o 75 minutos de ejercicio vigoroso por semana.
Por lo tanto, cuando se calcula por semana, esto sería un promedio de 20 minutos de ejercicio por día.
Andar en bicicleta, caminar, hacer jardinería y aeróbicos acuáticos son ejemplos prácticos de ejercicios leves o moderados que podrían aumentar el HDL. Sin embargo, el baile aeróbico, el trote y el salto de cuerda son ejemplos de ejercicios vigorosos que, cuando se combinan con la dieta y la pérdida de peso, conducen a una disminución del LDL.
This should be reversed, it should be a decrease in bad cholesterol and an increase in good cholesterol.
Basically, exercise boosts the HDL and lower triglycerides. Under normal conditions, Aerobic exercises do not reduce LDL. However, when combined with dietary changes and well-monitored weight loss the combined effect could lower LDL.
Under the standard conditions, the recommended exercise per week is 150 minutes of mild exercises or 75 minutes of vigorous exercise per week.
Therefore, when calculated per week this would be an average of 20 minutes of exercise per day.
Biking, walking, Gardening, and water aerobic are practical examples of mild or moderate exercises that could boost HDL. However, Aerobic dancing, jogging, and rope jumping are examples of vigorous exercises which when combined with dieting and weight losses leads to a lowering of LDL.

the apple."
Soledad: "There are two forces: the desk pushes up on the apple and gravity pulls
downward on the apple."
Misha: "There are many forces acting on the apple; but, it is the holding force in the
apple that keeps it on the desk."

Ethan filled 10 cups of the same size with equal amounts of water. He divided the cups into five groups of two cups each. The groups were placed in five different locations around his house. After two weeks, he measured the remaining water to determine how much had evaporated, by measuring how much water remained in each cup.
Answers
Answer:
See the answer below
Explanation:
Ethan filled 10 cups of the same size with equal amounts of water. He divided the cups into five groups of two cups each. The groups were placed in five different locations around his house. After two weeks, he measured the remaining water to determine how much had evaporated, by measuring how much water remained in each cup.
What is the dependent (data) variable?
A. Location of cups
B. Amount of time they were left in locations
C. Amount of evaporated water
D. Size of cups
The dependent variable is the variable whose value is dependent on other variables, particularly the independent variable, in the course of experiments. As the independent variable becomes varied during the experiment, the value of the dependent variable also varies along.
Hence, in this particular scenario, the dependent variable would be the amount of evaporated water. This amount would be dependent on the location of the cups around the house which, in this case, would be the independent variable.
The correct option is C.

When water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. Which property of water accounts for this occurrence
A) cohesion
B) pH
C) polarity
D) surface tension
Answers
Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
In water molecules hydrogen bonds provides a special dipole - dipole attraction. Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine). This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge. This makes the molecule of water polar. By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.This property of water is polarity of water.
The property of water that is at work as described in the question is polarity.
Water is composed of oppositely charged ends; a positive end and a negative end. These oppositely charged ends are called "dipoles".
The occurrence of dipoles in water makes water a polar molecule. Thus, when water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. This is possible because of the property of polarity possessed by water molecules.

what is different between leaching and erosion
Answers
Erosion is the natural process by which soil / rock are removed from the Earth's surface by exogenetic processes such as wind or water flow, transported and deposited in other locations. Leaching is the removal of soluble material from soil or other material by percolating water.
Erosion is the natural process by which soil / rock are removed from the Earth's surface by exogenetic processes whereas Leaching is the removal of soluble material from soil or other material by percolating water.
What do you mean by soil erosion?Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

Faults form in the lithosphere.
Plates move toward each other.
Answers
The statement that describes transform boundaries is "Faults form in the lithosphere," which is the third option, as transform boundaries occur where two tectonic plates slide past each other in opposite directions.
What are transform boundaries?
Transform boundaries are a type of plate boundary where two tectonic plates move past each other horizontally without being destroyed or created. They occur when two plates slide past each other. This sliding motion results in the formation of cracks or fractures in the lithosphere, which can cause earthquakes. The movement along transform boundaries is typically smooth but can be interrupted by sudden motions that release large amounts of energy and cause earthquakes.
Hence, the statement that describes transform boundaries is "Faults form in the lithosphere," which is the third option.
