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.
With your partner, decide on a plan for investigating the effect of exercise on heart rate. The exercise could be running in place or doing jumping jacks. Record the steps below.
Pls I need the answer fast
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

organisms to utilize is an example
of..
A. mutualism.
B. commensalism.
C. decomposition
The nitrogen fixation bacteria makes the nitrogen available for the plants directly into the soil. This is an example of mutualism, where both bacteria and organisms are benefited.
Most leguminous plants like peas, bans, and cloves have colonies of nitrogen fixation bacteria. These bacteria are found attached to the roots nodules and tend to fix the nitrogen. Through this, the bacteria gain sugar from the plant.Hence mutualism is the end product of the interaction. This option A is correct.

how sexual reproduction plays its role in avoiding genetic monotomy
Answer:
Abstract
The relative contributions of sexual and asexual reproduction to the genetic structure of populations can be difficult to determine for fungi that use a mixture of both types of propagation. Nuclear RFLPs and DNA fingerprints were used to make indirect and direct measures of departures from random mating in a population of the plant pathogenic fungus Mycosphaerella graminicola during the course of an epidemic cycle. DNA fingerprints resolved 617 different genotypes among 673 isolates sampled from a single field over a 3-month period. Only 7% of the isolates represented asexual clones that were found more than once in the sample. The most common clone was found four times. Genotypic diversity averaged 85% of its maximum possible value during the course of the epidemic. Analyses of multilocus structure showed that allelic distributions among RFLP loci were independent. Pairwise comparisons between individual RFLP loci showed that the majority of alleles at these loci were in gametic equilibrium. Though this fungus has the capacity for a significant level of asexual reproduction, each analysis suggested that M. graminicola populations maintain a genetic structure more consistent with random-mating over the course of an epidemic cycle.

Answer:
Blood type is an example of ✔ codominance
Explanation:
Blood type is determined by the ✔ antigens on the blood cells.
✔ Antibodies attack foreign blood that does not contain the same antigens.
Blood type is an illustration of codominance.
What is blood type?Blood group also known as blood type refers to classification of blood on the basis of the absence and presence of antibodies and inherited antigenic components on the red blood cells surface. These antigens may be:
ProteinsCarbohydratesGlycolipidsGlycoproteinsThe blood type in humans is an example of codominance. In codominance, neither of the allele can inhibit the expression of the other allele. One of the example is the ABO blood group in humans. In this, both the alleles A and B are expressed.
Therefore, if a person is inheriting allele A from the mother and allele B from the father, he or she will have the blood type AB.
Thus, blood type is an example of codominance.

What are the 3 common characteristics of planets? Describe one of the characteristics of one of the planets in our solar system
Answer:
The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core. Scientists count eight planets overall. Pluto was reclassified as a dwarf planet in 2006.
