3. A cell with 10 chromosomes undergoes mitosis.
(a) How many daughter cells are created:
Answers
Answer:
In a cell with 10 chromosomes undergoes mitosis, the result are 2 daughter cells each with 10 chromosomes
Explanation:
Cells have the ability to reproduce or replicate through 2 processes:
Mitosis
Meiosis
Mitosis differs from meiosis because the final result is always
2 daughter cells
The daughter cells are identical to the mother cell and this includes the same number of chromosomes
This means in mitosis 1 cell with 10 chromosomes leads to two identical cells each with 10 chromosomes.

3. What do you think most public water is used for?
Answers
Answer:
The Earth might seem like it has abundant water, but in fact less than 1 percent is available for human use. The rest is either salt water found in oceans, fresh water frozen in the polar ice caps, or too inaccessible for practical usage. While population and demand on freshwater resources are increasing, supply will always remain constant. And although it's true that the water cycle continuously returns water to Earth, it is not always returned to the same place, or in the same quantity and quality.

Answer:
The genetic material in the germline cells is passed onto offspring, not somatic cells.
Explanation:
A body cell is another terms for somatic cell. Germline cells refer to cells involved in reproduction, like the egg and sperm. During reproduction, only these cells combine to start creating the new life. Therefore, the genetic changes that occur in body cells have no effect on the offspring because the change is not also found in the germline cells. Should there be genetic changes in the germline cells, then these alterations would be present in the offspring.

Which compound can only be made if it has access to magnesium ions?
Answers
Answer:
Hope it helps
Explanation:
Green plants absorb light in their leaves and convert it to energy by photosynthesis. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.Plants need minerals for healthy growth. They are absorbed through the roots by active transport as mineral ions dissolved in the soil water.Magnesium ions and nitrate ions are needed by plants. A plant will not grow well if it cannot get enough of these ions, and it will show symptoms of mineral deficiency. Fertilisers are used to replace minerals used by plants.
Nitrogen fertilisers - such as ammonium nitrate and ammonium phosphate - provide plants with water-soluble sources of nitrogen that they can absorb through their roots. They allow farmers to increase the yield and quality of their crops. However, overuse can cause problems. Eutrophication happens when excess nitrate (or phosphate) enters rivers or lakes from fields. This can lead to the death of fish and other aquatic animals.

Pls helpthe sun hits the ocean at the equator more directly than at the poles. how does this support the flow of currents in the ocean?
Answers
The Sun creates a lot of thermal energy in the atmosphere and the oceans. Currents created as warm equatorial waters move to the north carrying heat. Due to this, the cold polar waters go south, and there get heated.
What is thermal energy?Thermal energy refers to the energy within a system and is responsible for its temperature.
The Sun heats up the air at the equator. This air will move toward the poles and cools down there with time.
In this process, the wind that occurs due to air currents will induce currents at the ocean surface.
The currents at this surface are propagated down deeper due to the differences in the forces on different parts of the water.
Thus, It is the main reason that the sun hits the ocean at the equator more directly than at the poles.

Lab: exercise and homeostasis lab report
if anyone has done this pls help
ill give brainliest
Answers
Introduction:
The question that was trying to be answered in this lab was “How does exercise affect a person’s heart rate, breathing rate, and perspiration level?” Based on this question, the hypothesis that was formed was “If effects of exercise and exercise are related, then exercising will increase heart rate, breathing rate, and perspiration level”.
What is homeostasis?Homeostasis refers to the mechanism of the body to maintain a stable internal environment instead of changes taking place in the external environment.
Homeostasis in the body is maintained through three vital organs, as mentioned before, the kidneys, liver, and brain. These regulate the temperature, iron content in our blood, retention, and production of energy and overall blood composition. This was helpful because the whole lab report was based on homeostasis and the effect that it had on exercise.
Materials and Methods:
1. Materials:
a. People to exercise
b. A clock or stop watch
2. Procedure:
Choose one volunteer to complete jumping jacks at a pace that can be maintained for eight minutes. Make sure the volunteer is inactive for a few minutes before the experiment begins.Measure the heart rate by taking his or her pulse, you can do this one of two ways: Radial Pulse, Carotid PulseMultiply the number of beats in 15 seconds by 4 to calculate the beats per minute. Record the data in the table below the 0 minutes box.Measure the person’s perspiration level from 0 to 5: (0 = none; 5 = droplets dripping down the face). Note this observation in the table. Have the volunteer do jumping jacks for 2 minutes. After 2 minutes, measure the heart rate, breathing rate, and perspiration level (refer to steps 2 through 5), and record the data. Measure the pulse, breathing and perspiration levels as quickly as you can so that the volunteer can resume exercise. Do not have volunteer wait while you do the calculations and enter the data. Repeat step 6 three more times (remember, 2 minutes each at a time, totaling 8 minutes) and record your data at each point. After the final recording of the dependent variables, wait one minute with the volunteer at reset. Then measure all of the variables again. Record this data under the “9 Time (Min.) Box”.Analysis:
There is an increase effect of exercise over time on the circulatory and respiratory systems, as shown in both Table 1 and Table 2. As the students began their exercise in two-minute intervals, their heart rates increased on average from 73 beats per minute to 115 beats per minute. Shawn’s individual heart rate began at 84 beats per minute, and after lifting 5-pound weights for 8 minutes, his heart rate increased to 114 beats per minute . Also, his breathing rate showed an increase from 36 breaths per minute to 44 breaths per minute.
Based on this data shown, the amount that you exercise does effect the circulatory and respiratory systems by causing a, on average, dramatic increase in beats/breath per minute in the measured variables.
Conclusion:
According to the data collected, the hypothesis that was developed at the beginning of the experiment: “If effects of exercise and exercise are related, then exercising will increase heart rate, breathing rate, and perspiration levels”; was accepted . Based on the data shown our individual group charts and the class averages, the effect that exercise has on the respiratory and circulatory systems is that it develops an increase in heart rate (Start: 73/ Finish: 115), breathing rate (Start: 38/ Finish: 56), and perspiration levels (Start: 0/ Finish: 1).
