Answer:
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Explanation:
By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).
Explain the difference between the three types of selection
Th difference between the three type of selection has been that stabilization selection keeps allele frequency constant, direction selection changes the allele frequency over generation, while disruptive selection maintain high allele frequency.
What is natural selection ?
Natural selection is the process by which populations of organisms adapt and change.
The 3 Types of Natural Selection
Stabilizing SelectionDirectional SelectionDisruptive SelectionStabilizing SelectionStabilizing selection is natural selection that keeps allele frequencies relatively constant from generation to generation. In other words, unless the environment changes, things stay the same.
A classic example of stabilizing selection is human birth weight Very low birth weight and very high birth weight are mutually selected to keep the mean birth weight
Directional SelectionDirectional selection is a natural selection that causes gradual changes in allele frequencies over several generations. This usually occurs when environmental/selection pressures change or when favorable new alleles emerge within the population.
Example: Recent findings show that climate change is affecting fish size in certain habitats.
Disruptive SelectionDestructive selection is natural selection that maintains high frequencies of two different allele sets. In other words, individuals with intermediate phenotypes or alleles are selected.
Destructive selection causes polymorphism: the persistence of two or more distinct phenotypes in species . This can occur in environments that exhibit variability.
For example, birds in the Galapagos Islands use their beaks to forage seeds of various sizes.
Therefore, the difference between the three types of natural selection is that:
Stabilizing selection keeps allele frequencies relatively constant from generation to generation.
Directional selection causes gradual changes in allele frequencies over several generations.
Destructive selection maintains high frequencies of two different allele sets.

Place 14 oz of crushed ice into a small pot. Then add about 125 mL of water to it.
Using the thermometer, measure and record the initial temperature of the ice water. List this temperature in °C in the “0” minutes row of your data table in the lab handout. *Do not allow the thermometer to touch the bottom of the pot when recording measurements.
Place the pot on the stove, and turn the knob to the medium-low setting.
Using the thermometer, measure the temperature every minute until the water begins to boil vigorously. Record this data in the table on your lab handout.
At each measurement, also record what is happening to the water. Be sure to record the times of these events:
The ice melts.
The water forms steam.
The water begins to boil.
Once the water has begun to boil, stir the water constantly with the spoon.
Continue to measure and record the temperature every minute until almost all the water has boiled and the pot is close to empty.
Record the last temperature, and turn off the stove. DO NOT TOUCH THE POT WITHOUT SAFETY EQUIPMENT.
Create the x-axis and y-axis of a graph.
Label the x-axis as follows: Time (min).
Label the y-axis as follows: Temperature of Water (°C).
Along the x-axis, create and label 15 marks, one for each minute of the experiment. (Hint: The origin starts at 0.)
Along the y-axis, create and label temperature markings for every 20 degrees. (Hint: The origin starts at 0.)
Refer to the data from your experiment to plot the points on your graph. Then connect each of the data points with a line.
Look over your graph to make sure it is clear and correctly labeled.
Either save your graph as a computer file, or take a picture of your graph and upload it as a file on your computer.
Describe your experience in performing the experiment. What went well? What could have been
improved?
Examine your line graph. How does the graph’s slope change over time?
Examine your line graph. Why does the slope change?
How could you apply the knowledge gained from this experiment in the real world?

Answer:
A. freeze at the same temperature at which it melts, depending on whether the temperature is rising or falling.
Explanation:
Option A is the correct.
Freezing and melting are two changes that occur in the state of matter. Freezing is known to be the change that occurs when a substance (liquid) changes to solid when there is a decrease in temperature. While melting is known to be the opposite and it refers to the change that occurs when a solid changes to liquid as a result of increase in temperature.
When substances freeze, they do so in the same temperature as they melt. This is true because both freezing and melting actually describe similar transition of matter. So, it depends whether temperature is rising or whether it is falling.

A que se denomina metaboismo? Diferenca anabolismo de catabolimo da 4 ejemplos diferencia reaccion endegonica de exergonica
Answer and Explanation:
Metabolismo: El término hace referencia a todos los cambios y las reacciones quimicas y biológicas que ocurren en cada célula del organismo y que resultas escenciales para el funcionamiento adecuado del organismo (una buena nutrición, crecimiento, reparación celular, conversion energética, etc.).
Estas reacciones ocurren a lo largo de toda la vida del organismo. Cada celula toma sustancias que luego modifica químicamente para integrarlas como nuevos componentes celulares. Algunos de estos componentes son utilizados en reacciones como la respiración celular.
El metabolismo puede ser dividido en anabolismo y en catabolismo. Durante el anabolismo suceden reacciones que consumen energía (ATP) para sintetizar moléculas complejas a partir de moléculas simples, y que son necesarias para el funcionamiento del organismo. Mientras que durante el catabolismo suceden reacciones que liberan energía al deegradar o reducir moléculas grandes en otras mas simples, para que el cuerpo pueda asimilarlas y las transforme en energia (ATP). Esta energía luego será utilizada en los procesos anabólicos.
Ejemplos:
- Respiración celular: Degradación de molécula del glucosa para liberar y obtener energía y consecuentemente, moleculas mas simples (CATABOLISMO)
- Ciclo de Krebs: Oxidación de la molécula acetil-CoA y obtención de energía en forma de ATP (CATABOLISMO).
- Digestión: Degradación del alimento para obtener elementos mas asimilables por la célula y energía (CATABOLISMO).
- Degradación de ADN y ARN (CATABOLISMO).
- Fotosíntesis: Transformación de compuestos inorgánicos en orgánicos utilizando energía solar (ANABOLISMO).
- Síntesis proteica: Utiliza aminoácidos y energía para formar proteinas necesarias para el organismo (ANABOLISMO).
- Ciclo de Calvin: Usa moléculas de CO2 para formar glucosa (ANABOLISMO).
- Gluconeogénesis: Síntesis de glucosa a partir de precursores diferentes a los glúcidos (ANABOLISMO).
Reacción excergónica: reacción espontánea que se lleva a cabo y donde se produce la liberación de energía. No necesita energía para suceder.Reacción endergónica: reacción no espontánea. Necesita energía para suceder. Ocurren reacciones celulares a partir del consumo de energía.Which statement below best explain the difference between microevolution and macroevolution

A new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction. true or false
Answer:
True
Explanation:
It is true that a new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction.
This happens due to physical separation of members of a population.
Geographic isolation :Geographic isolation occurs when populations are separated by geographical barriers like rivers, mountain etc.The population is separated from exchanging genetic material within the same species and results in evolution of a different trait.

If you drink a gallon or more of fresh water at a single sitting, what happens to your blood and then what might happen to the cells in the blood?
Answer:
I hope this will help
Explanation:
When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.
Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.

How do you think about the invention of the microscope? Influenced the cell theory?
And what are the components of the cell theory?
Answer:
See the answer below
Explanation:
The invention of the microscope paved way for the development of the cell theory because, without it, the cell and all the organelles of the cell would not have been discovered and or studied in great detail. It was through the use of a microscope that Robert Hooke was able to observe and name the cell and it was through the same microscope that the fine details of the cell were able to be studied by other scientists, culminating in the formulation of the cell theory.
The cell theory states that all living organisms are made up of cells, the cell is the basic unit of all life, and cells can only arise from already existing cells (via cell division). The components of the cell theory, therefore, are:
Living organisms are made up of cells.The cell represents the basic unit of life.Cells can only arise from preexsiting cells.What does an ecopsychologist study? a. the mental health of environmental scientists b. the relationship between animals' interactions and their mental health c. the relationship between animals' behavior and the environment d. the relationship between a person's mental health and the environment
