Question: How are the amounts of oxygen and carbon dioxide related to each other?

Observe: Put two Elodea sprigs into a test tube. Put the O2/CO2 probe into the tube with the Elodea. Click Play. As the Gizmo runs, Pause () it a few times.

A.
How do the oxygen (O2) and carbon dioxide (CO2) levels change over time?


B.
What is always true about the total amount of O2 and CO2 in the test tube?


C.
What happens when the CO2 reaches zero?




Revise and repeat: Click Reset. Remove the plants. Repeat the experiment with two snails.

A.
How do the gas levels change?
O2


CO2












B.
What is the total of O2 and CO2?








Challenge: In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:

6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy

How do these equations explain why the total amount of O2 and CO2 remains the same?

Answer:

As the sweat evaporates off your skin, you cool down. Sweat is a great cooling system.

Explanation:

Answer: When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down. Sweat is a great cooling system, but if you're sweating a lot on a hot day or after playing hard you could be losing too much water through your skin.

Answer:

24 * 10 ^ 13 electrones

Explanation:

Tenemos la siguiente información;

Carga en un solo electrón = -1.6x10-19 C

Carga en el electrón en consideración = -38 uC o -38 * 10 ^ -6 C

Ahora,

si la carga en 1electron es -1.6x10-19 C

x electrones tienen una carga de -38 * 10 ^ -6 C

X = -38 * 10 ^ -6 C / -1.6x10-19 C

24 * 10 ^ 13 electrones

Answer:

Explanation:

Answer:

1km/hr every 1.5 minutes

Explanation:

The acceleration is 40 km/hr²

The initial velocity of the car is= 35km/hr

The Final velocity of the car is = 45km/hr

The Time taken by the car is = 0.25

Acceleration= velocity/time

= 45-35/0.25

= 10/0.25

= 40

Acceleration is 40 km/hr²

Explanation:

Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!

Answer:

C - Animals competing with each other

Explanation:

C is the only one that doesn’t give evidence of evolution

A shows the similarities between the skeletons in different animals. This can help scientists see what organisms have similar structures and what animals they could have evolved from

B shows what organisms could share a common ancestor. Homologous means that the organisms have the same structure in some part of them. Vestigal means the organism has a part to it’s body that is useless. This easily shows what organisms could have a common ancestor

D shows how animals could have evolved from living in the water to being able to survive on land. Pretty self-explanatory

Animals have always competed with each other, so that doesn’t give any evidence of evolution

Answer:

The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration (in which plants release water from their leaves during photosynthesis). This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest.

Answer:

B) 5m/s^2

Explanation:

The formula for acceleration is [tex]\frac{vf-vi}{t}[/tex]

vf is the final velocity which in this question is 25m/s

vi is the initial velocity which in this question in 0m/s because it says "A stopped car"

t is the time which is 5 seconds

When you put these numbers into the formula you get 5m/s^2

Explanation:

cellular respiration is the process of taking organic molecules like C6H12O6 and breaking them down for energy, ATP. Regardless of whether cellular respiration occurs in plants or animals it is the same process, just plants get their C6H12O6 from photosynthesis while animals get it from food

Explanation:

Biomagnification is the process by which toxins and pollutants become increasingly concentrated in the bodies of animals as they move up the food chain. This means that organisms at the top of the food chain, such as humans, can end up with dangerously high levels of these pollutants in their bodies if they consume contaminated prey.

This phenomenon is particularly concerning when it comes to certain toxins, such as mercury and persistent organic pollutants (POPs) like PCBs and DDT. These toxins can have serious health consequences, including neurological damage, developmental delays, and cancer.

One example of biomagnification in action is with mercury contamination in fish. Mercury is released into the environment through various human activities, including burning coal and waste incineration. When this mercury enters waterways, it can be transformed into methylmercury, a highly toxic form that accumulates in the tissues of fish and other aquatic organisms.

As larger fish consume smaller fish, the concentration of methylmercury in their bodies increases, leading to dangerously high levels in the bodies of top predators like sharks and swordfish. When humans consume these contaminated fish, they can also accumulate dangerous levels of methylmercury in their bodies.

Similarly, POPs like PCBs and DDT can enter the food chain through contaminated soil and water. As these toxins move up the food chain, they become increasingly concentrated in the bodies of top predators like birds of prey and mammals like seals and polar bears.

These toxins can have serious health consequences for these animals, including reproductive problems and weakened immune systems. When humans consume these contaminated animals, they can also accumulate dangerous levels of these toxins in their bodies.

Biomagnification is a serious issue that highlights the importance of careful monitoring of environmental pollutants and the need for sustainable practices to prevent contamination in the first place.
