CAN SOMEONE PLEASE HELP ME WITH THIS PLEASE I WANT TO PASS!!!

Answer:

Materials

• Scrap piece of paper

• Pen or pencil

• Clock or timer that shows seconds or a helper with a watch

• Comfortable exercise clothes (optional)

• Calculator

Preparation

• Practice finding your pulse. Use the first two fingers of one hand to feel your radial pulse on the opposite wrist. You should find your radial pulse on the "thumb side" of your wrist, just below the base of your hand. Practice finding your pulse until you can do it quickly. (You can alternatively take your carotid pulse to do this activity, but be sure you know how to safely take it and press on your neck only very lightly with your fingers.)

• Measure your resting heart rate, which is your heart rate when you are awake but relaxed, such as when you have been lying still for several minutes. To do this, take your pulse when you have been resting and multiply the number of beats you count in 10 seconds by six. This will give you your resting heart rate in beats per minute (bpm). What is your resting heart rate? Write it on a scrap piece of paper.

• You will be measuring your heart rate during different types of physical exercises over a period of 15 minutes. Choose at least two different exercises. Some examples include jumping rope, lifting a two-pound weight, riding a bike, hula-hooping, walking, etc. Gather any needed materials. (If you want to make a homemade hula-hoop, steps for doing this are given in the activity Swiveling Science: Applying Physics to Hula-Hooping .) Do you think the activities will affect your heart rate differently? How do you think doing each activity will affect your heart rate?

Procedure

• Choose which exercise you want to do first. Before starting it, make sure you have been resting for a few minutes so that your heart is at its resting heart rate.  

• Perform the first exercise for 15 minutes. While you do this, write down the number of beats you count in 10 seconds after one, two, five, 10 and 15 minutes of activity. (You want to quickly check your pulse because it can start to slow within 15 seconds of stopping exercising.) How do the number of beats you count change over time? How did you feel by the end of the exercise?

• Calculate your heart rate after one, two, five, 10 and 15 minutes of exercise by multiplying the number of beats you counted (in 10 seconds) by six. How did your heart rate (in bpm) change over time?

• Repeat this process for at least one other exercise. Leave enough time between the exercises so that your heart rate returns to around its normal resting level (this should only take a few minutes). How did you feel by the end of the second exercise? How did your heart rate change over time for this exercise?  

• Take a look at the results you wrote down for this activity. Which exercise increased your heart rate the most? Which exercise increased your heart rate the fastest? Which exercise(s) elevated your heart rate to the target heart rate zone (50 to 85 percent of your maximum heart rate, where your maximum heart rate is 220 bpm minus your age)? Do you notice any consistent patterns in your results?

• Extra: Try this activity again but test different physical exercises. How does your heart rate change when you do other exercises? How are the changes similar and how are they different?

• Extra: Measure your heart rate while lying down, while sitting down, and while standing. How does your heart rate change with body position?  

• Extra: Repeat this activity with other healthy volunteers. How does their heart rate compare to yours? How does their change in heart rate while exercising compare to how yours changed?  

• Extra: Try this activity again but vary the intensity of your exercise. What intensity level elevates your heart rate to 50 percent of its maximum heart rate? What about nearly 85 percent of its maximum? Be sure not to exceed your recommended target heart rate zone while exercising

Explanation:

If you did a moderately intense exercise, such as walking, you may have seen an initial jump in your heart rate (where your heart rate falls within the lower end of your target heart rate zone within about one minute of exercise), but then your heart rate only slowly increased after that. After 15 minutes, you may have reached the middle of your target heart rate zone. To reach the upper end, people usually need to do a moderately intense exercise for a longer amount of time (such as for 30 minutes). If you did a more strenuous exercise—hula-hooping, for example—you may have seen a higher initial bump in your heart rate (such as reaching the middle of your target heart rate zone after just one minute of exercise), and then your heart rate stayed about the same for the remaining 14 minutes of exercise. Overall doing a more strenuous exercise generally raises a person's heart rate faster compared to doing an exercise that is only moderately i

Answer:Metaphase

Explanation:

Answer:

Multicellular organisms.

Explanation:

Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms.

Answer: Anything living needs to have certain conditions, if for example a group of flightless birds who are adapted for warm weather had their environment get colder each year and more extreme the surrounding plants and other animals may have a difficult time surviving and this will cause the birds to have less food. The birds also will not be accustomed to these changes and will not be able to adapt their bodies fast enough. This also makes reproduction difficult and in turn further dwindles the population.

Answer:

Contact inhibition.

Explanation:

Contact inhibition is a response of a cell in which cell growth stopped when it touches or comes in contact with another cell. When the normal and healthy cells grows and touching other cells, the cell receives a red light signal to stop its growth so the cell stop its growth while on the other hand, if there is no contact with other cell the cell continues its growth.

Answer:GGU

Explanation:

GGU. I just completed it on gizmos

The tRNA molecules in Lucy's white blood cells. RNA Pairing Rules A ↔ U ​​​​G ↔ C Anticodon CCA Codon GGU.

Once the mRNA codon has been translated by the ribosome, transfer RNA, also known as tRNA, is in charge of directing the appropriate amino acid into protein synthesis. Because of this, each mRNA codon needs a corresponding tRNA anticodon.

Each nitrogenous base in RNA must mate with a complementary base according to the following rules:

Adenine is complementary with uracil A=U

Cytosine is complementary with Guanine C=G

In this case, it can be seen that:

Therefore, for the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).

Answer:

methionine-proline-glycine-leucine-stop

Explanation:

Using an amino acids chart, you can line up the 3 bases in each section to find the protein chain that corresponds. The stop at the end marks the end of protein synthesis, which ends the sequence.

The compound comprising carboxylic and amino groups is called amino acids. They are vital for the formation of proteins in the cells.

Sequences are read in the three pairs of codons in the form of triplets to form a form an amino acids sequence.

The amino acid sequence that will be formed from the given sequence AUG-CCC-GGA-UUA-UAG will be:

methionine-proline-glycine-leucine-amber

Therefore, Met-Pro- Gly- Leu- Amber is the amino acid sequence.

Answer:

1.732 seconds

[tex]s=ut+\dfrac{1}{2}at^2[/tex]

Explanation:

s = Displacement of ball = 15 m

g = a = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]

u = Initial velocity of the ball = 0

t = Time taken

From the kinematic equations we use the following formula

[tex]s=ut+\dfrac{1}{2}at^2\\\Rightarrow 15=0t+\dfrac{1}{2}\times 10t^2\\\Rightarrow t=\sqrt{\dfrac{15\times 2}{10}}\\\Rightarrow t=\sqrt{3}=1.732\ \text{s}[/tex]

The object will reach the ground after 1.732 seconds.

The formula used is [tex]s=ut+\dfrac{1}{2}at^2[/tex].

See the answer below

Explanation:

The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.

Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.

The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.

The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.

Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.

Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.

Answer:

Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.

Explanation:

The Adenosine Triphosphate (ATP) is a molecule made of adenine, ribose, and three phosphate groups, which are the ones that store the energy in its bounds.  The ATP is the molecule that provides the energy to the different processes that happen in a cell. The molecule is made from the glycogen, fats, and carbohydrates that the body has absorbed in the intestines. When the body needs energy, the ATP loses one or two phosphates, becoming ADP and AMP. When the phosphorylation happens, which is the loss of phosphate, the energy is released.
