Select the answer that best describes the relationship between photosynthesis and cellular respiration.
Question 5 options:
Cellular respiration and photosynthesis have a linear relationship where cellular respiration creates energy for photosynthesis to occur.
Photosynthesis uses light eneregy to create the carbon dioxide needed for cellular respiration to occur while cellular respiration also creates carbon dioxide that is released into the atomosphere. This creates a positive feedback loop of carbon dioxide production.
Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen which is needed for cellular respiration to occur. Cellular respiration takes the glucose and oxgyen and produces water and carbon dioxide that is needed for photosynthesis while also producing energy.
Celluar respiration uses the energy from the sun to create ATP which is used in the process of photosynthesis to produce oxygen and water which are essential to life on this planet.
C. ''Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen which is needed for cellular respiration to occur.
Cellular respiration takes the glucose and oxygen and produces water and carbon dioxide that is needed for photosynthesis while also producing energy'' this is the correct answer.
What is the difference between Photosynthesis and respiration?Photosynthesis is a process that occurs in the body of plants in which carbon dioxide and water are converted into oxygen and glucose in the presence of light energy. In this process of photosynthesis, oxygen is released into the atmosphere whereas glucose is stored in different parts of the plant body.
Glucose is used as food by the plant generating energy in the form of ATP and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide with the release of energy. Water and carbon dioxide are the by-products of cellular respiration and ATP is energy that is transformed from the process of cellular respiration.
So we can conclude that option C is the correct answer.

4. What is the energy balance or energy budget in relation to the Sun and Earth?
Answer: Earth’s energy budget describes the balance between the radiant energy that reaches Earth from the sun and the energy that flows from Earth back out to space. Energy from the sun is mostly in the visible portion of the electromagnetic spectrum.
Explanation:
The energy balance between the earth and atmosphere is reached when the energy from the Sun equals the energy that is lost by the Earth back into space. The Earth maintains a steady average temperature and a steady climate in this way.
What energy balance in relation to the Sun and Earth?The balance between the solar energy that enters Earth and the energy that leaves Earth and travels back into space is known as the Earth's energy budget. The visible region of the electromagnetic spectrum is where the majority of the sun's energy is found.
With greenhouse gases in the atmosphere helping to keep the planet habitable, the temperature of the Earth is a delicate balancing act. Multiple mechanisms work together to maintain this temperature balance.

separated from each other.
B) The chromosome number per cell is conserved.
C) Sister chromatids are separated.
D) Four daughter cells are formed.
In meiosis I, homologous chromosomes of a pair are separated from each other. Option A.
What is meiosis?Meiosis is otherwise known as the division of sex cells or reductional division. It is a division in which diploid cells divide to produce haploid cells.
Meiosis occurs in 2 main stages:
Meiosis IMeiosis IIMeiosis I consists of prophase I, metaphase I, anaphase I, and telophase I. Meiosis II, on the other hand, consists of prophase II, metaphase II, anaphase II, and telophase II.
At the prophase I stage of meiosis I, chromatin materials thicken to form threads and homologous chromosomes pair up to form a tetrad. Non-sister chromatids then go ahead to exchange chromosomal segments in a process known as crossing over.
At metaphase I, paired homologous chromosomes line up at the center of the cell to form a metaphase plate. Spindle fibers engage each tetrad.
At anaphase I, homologous chromosomes of a pair are pulled apart by the shortening of the spindle fibers. Their journey to the poles is completed at telophase I. This effectively ends the journey of meiosis I before the cell proceeds to meiosis II.
In other words, the separation of homologous chromosomes of a pair happens during meiosis I.
