#4-6-Base your answers to questions #4-6 on the information below and on your knowledge of biology. Five individuals had their pulses taken in beats per minute (bpm) before and after exercise. The data are shown in the chart below. 4. State one reason why an individual's pulse rate increased during exercise 5. Calculate the average pulse rate before exercise for this group, to the nearest tenth___________bpm . 6. State why the individuals in this group have different pulse rates before exercise *
Answer:
4. (answered below); 5. 66.2; 6. (answered below)
Explanation:
4. The individual's heart rate increased because the individual needs more oxygen supplied to their muscles so the heart has to pump the oxygenated blood through the body at a faster rate.
5. Take average of the number of the pulse before exercise:
(68 + 70 + 54 + 64 + 75) / 5 = 66.2
6. Different individuals are different sizes and are in different states of health. An individual who is more physically fit will have a slower rate rate because their heart muscle is "exercised" or worked more and pumps blood more efficiently.

The brown circle A is an effector, and the blue circle B is a receptor.
The brown circle A is a receptor, and the blue circle B is an effector.
The brown circle A shows neurotransmitters being absorbed, and the blue circle B shows neurotransmitters being
released.
Answer:
The brown circle A is a receptor, and the blue circle B is an effector.
Explanation:
The brown circle indicates a receptor whereas the blue circle is an effector because brown circle have sensory cells which receives the sensation due to pins into the foot and this information is taken to the central nervous system through sensory neurons while on the other hand, blue circle is an effector to which instructions comes from the central nervous system through motor neurons and as a result the dog pulls away its foot from the region where pin is placed.
Answer:
C. The brown circle A is a receptor, and the blue circle B is an effector.

How might green spaces help reduce the negative impact that humans have on Earth’s water supply?
It would give nature a place to fight back, and become more healthy, and less hindered. Cities mess up the evaporation cycle, and because of parks, the water is able to be soaked up by grass, and then released through evaporation. When it rains over a city, the water goes into gutters, and becomes more polluted.
How is the small intestine designed to absorb digested food ?
Answer:
Small intestine is designed to more and more area for absorption of digested food and transfer into the blood for circulation throughout the body. The inner lining of small intestine has a large number of finger-like projections called villi. These villi provide a large surface area for absorption of food.
Explanation:
Hope this helps!
Have a good day or night!
➜ The small intestine is the main region for the absorption of digested food. The inner lining of small intestine has millions of tiny finger-like projections called villi. The presence of villi gives the inner walls of the small intestine a very large surface area for absorption of digested food. The villi are richly supplied with blood vessels which take the absorbed food to each and every cell of the body.
Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. decrease the rate of oxygen diffusion from the alveoli to the blood. increase the partial pressure of carbon dioxide in the alveoli. decrease the rate of carbon dioxide diffusion from the blood to the alveoli. have no effect on either the partial pressure or diffusion rate of gases.
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
Describe three ways in which economies are
likely to be affected by climate change
Answer:
1. Climate change affect the geography within which economy of the world operate
2. It changes the comfortability of human within the global industry
3. Growth Zone is affected
Explanation:
1. Climate change affect the geography within which economy of the world operate: economic of the world are affected by change in climatic condition in the since that there is shift in the usual period of seasons. For example, taken Nigeria as a region in West Africa, rainfall is expected to start around March in almost all part of the country, however, due to climate change, some part don't still have rain till May. This causes a shift in farmers plan and affect the supply of farm produce to the local market and to the global market, in turn affecting the gross domestic product of the country.
2. It changes the comfortability of human within the global industry. Take for example, fossil fuel, it is part of human being to address some unfavourable conditions among which is climate change which causes global warming, during this period, the way industries and people uses fossil fuel are been changed and it have direct effect to global economy.
3. Growth Zone is affected: change in climatic condition changes world economy growth zones. Thus could be seen in transportation sector, when the water level is affected, international movement of cargoes by ship are affect and hence, some trades agreements are altered thereby changing the growth zone.

Sickle cell anemia is an inherited form of anemia - a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body.
Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like
sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels. How does sickle cell anemia affect the blood flow in a human?
Answer:
RBCs are round red blood cells that easily move through blood vessels and carry oxygen with them to provide cells oxygen. In sickle cell anemia, the shape of the red blood cells is like sickles or crescent moons.
These cells occur due to mutation on the gene that produces this protein which results in rigid, sticky cells that can get stuck in small blood vessels and blocks the flow of blood, oxygen to parts of the body.
