You will measure and compare the heart rates of ten learners before and after
exercise. Choose ten learners in class who are willing to participate in this activity
They are the runners. Each of these runners must choose a classmate who will
measure his or her pulse rate.
Write down the question you are trying to answer in this investigation.
1.Write a hypothesis about the relationship between exercise and heart rate.
Answer:
Exercise is responsible for the increasing heart beat.
Explanation:
Exercise is responsible for the increasing heart beat because our body needs oxygen more faster during exercise. When we exercise our body needs quick energy and oxygen which can be provided by heart as well as the heart also removes carbondioxide which is produces during respiration process so the heart beat increases in order to provide energy and oxygen to the muscles.

You will build a simulation of a population using the same elements as the simulation pictured here and show how
the traits in this population change in years 5 and 10.
- Trait A
- Trait B
- Trait
1 circle = 50 organisms
Start off with 2,500 plants of which 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip
leaves. Each circle in your simulation will represent 125 organisms. Calculate how many circles you need for each
trait, and then create your simulation. Be sure to include a key that states the color coding for each trait.
According to the concepts of percentage and proportions, we can make the simulation with 20 circles, each of them representing 125 plants. Traits A = 10 circles. Trait B = 5 circles. Trait C = 5 circles.
To solve this problem, we need to know two concepts, percentage and proportion.
What is a percentage?A percentage can be defined as a fraction or a part of 100. It is denominated as percent (symbol %).
100 refers to the number of parts into which the unit has been divided.
So, X% means that for every 100 parts, X parts are of our interest. Or, that we are interested in X fraction from a total of 100 parts.
What is a proportion?A proportion is the equal relationship between two determined ratios or quantities.
In the exposed example we need to represent this population of 2500 plants with circles.
We know that,
Each circle represents 125 plants50% of the population have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves .So here, our unit is the population. We can say that our population of 2500 plants is composed by 100 subunits or parts.
2500 plants ------------ 100 parts
So now we will calculate how many plants are represented by the 50% and 25% of the population.
If 100% of the population equals 2500 plants, how many plants are 50% of the population and 25% of the population.
100% -------------------- 2500 plants
50% -------------------- X = (50% x 2500 plants) / 100% = 1250 plants.
25% ---------------------X = (25% x 2500 plants) / 100% = 625 plants
Now we know that from the total of 2500 (100%) plants,
1250 (50%) have medium-tip leaves, 625 (25%) have wide-tip leaves, and 625 (25%) have drip-tip leaves.Finally, we need to calculate how many circles represent these numbers. So, we know that 1 circle equals 125 plants. The question is, how many circles represent 2500, 1250 and 625 plants.
125 plants ----------------- 1 circle
2500 plants -------------X = (1 circle x 2500 plants) / 125 plants= 20 circles.
1250 plants --------------X = (1 circle x 1250 plants) / 125 plants = 10 circles.
625 plants ---------------X = (1 circle x 625 plants) / 125 plants = 5 circles.
So, our simulation must have 20 circles, from which
10 circles represent medium-tip leaved plants (Trait A), 5 circles represent wide-tip leaved plants (Trait B), and the remaining 5 circles represent drip-tip leaved plants (Trait C).In the attached files you will find the image.

Human blood is 90% water and 10% solute. What would happen if you gave
a patient an IV of pure water (0% solute)? The patient's cells will
remain unchanged.
swell or lyse.
shrivel.
Answer:
When a person receives fluids intravenously (through an IV bag, for example), a saline solution is sometime used. Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.
Explanation:
The answer is B: It swells.
A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.
what diseases can affect the digestive system?
what diseases can affect the respiratory system?
how do these diseases in each of these organ systems disrupt homeostasis?
Answer:
Lots of things can effect the lungs and GI systems from virus to bacteria. Any illness in either location can upset homeostasis. homeostasis is just the baseline normal of a human. So, if an illness causes fever then it upsets the balance, both chemical as well as hormonal.
Marine iguanas feed on seaweed. Seaweed contains starch Starch is digested by enzymes in the digestive system. Explain why the shape of an enzyme is important for digestion.
Answer: The enzyme is a catalyst that speed up the rate of the reaction.
Explanation:
The enzyme can be defined as the protein that is involved in the catalytic activity of the reaction. The shape of the enzyme is important as it determines to which substrate it binds to. The enzyme is specific to the substrate and binds to a specific kind of substrate. During the digestion process the enzyme binds to the specific substrate like protein, carbohydrates, fats, and other biomolecules present in the food to simplify the digestion process. Starch is digested into maltose by the enzyme salivary amylase in the mouth.

Is the following cell a plant of an animal cell? How do you know? Plant cell because there is a cell wall and a chloroplast O Plant cell because there is a large vacuole and a cell wall 0 Animal cell because there is a cell membrane and no chloroplasts O Animal cell because it has a cell wall and a a large vacuole
Answer:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.

La principal función del aparato respiratorio es inhalar oxígeno y eliminar dióxido de carbono. El oxígeno inhalado penetra en los pulmones y alcanza los alvéolos. Las capas de células que revisten los alvéolos y los capilares circundantes se disponen ocupando el espesor de una sola célula y están en contacto estrecho unas con otras. Esta barrera entre el aire y la sangre tiene un grosor aproximado de una micra (1/10 000 cm). El oxígeno atraviesa rápidamente esta barrera aire–sangre y llega hasta la sangre que circula por los capilares. Igualmente, el dióxido de carbono pasa de la sangre al interior de los alvéolos, desde donde es exhalado al exterior.
La sangre oxigenada circula desde los pulmones por las venas pulmonares y, al llegar al lado izquierdo del corazón, es bombeada hacia el resto del organismo (véase Función del corazón). La sangre con déficit de oxígeno y cargada de dióxido de carbono vuelve al lado derecho del corazón a través de dos grandes venas: la vena cava inferior y la vena cava superior. A continuación, la sangre es impulsada a través de la arteria pulmonar hacia los pulmones, donde recoge el oxígeno y libera el dióxido de carbono.
Intercambio de gases entre las alveolas y los capilares
Para mantener la absorción de oxígeno y la emisión de dióxido de carbono, entran y salen de los pulmones entre 5 y 8 L de aire por minuto, y cada minuto se transfiere alrededor del 30% de cada litro (cerca de tres décimos de galón) de oxígeno desde los alvéolos hasta la sangre, aun cuando la persona esté en reposo. Al mismo tiempo, un volumen similar de dióxido de carbono pasa de la sangre a los alvéolos y es exhalado. Durante el ejercicio, es posible respirar más de 100 L de aire por minuto y extraer de este aire 3 L de oxígeno por minuto. La velocidad de entrada del oxígeno en el organismo es una medida importante de la cantidad total de energía consumida por este. La inspiración y la espiración se llevan a cabo gracias a los músculos respiratorios.

Pls help quick plzzzzzzzz
1. Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.
2. Germination:When a seed falls on the ground, it needs warmth and water in order to germinate; some seeds also need light. Dicots have seed coats that soften with moisture. After being planted in the soil for a few days, the seed absorbs water and swells until the seed coat splits.

A) Karen: I think they must all be different species of ladybugs.
B)Troy: I think each ladybug has the same number of spots as its parents.
C)Isaac: I think it depends on the age of the ladybugs. As they get older they add more spots.
D)Fred: I think it has to do with the sex of the ladybug. Males will add more spots to compete for the females.
E) Andrea: I think it depends on what each ladybug was born with.
F) Alice: I think they change their number of spots when there is a need for them to do so.
