D. The mitochondria use carbon dioxide, water, and sunlight to
produce sugars and oxygen.
Answer:
B
Explanation:
the equation for photosynthesis is:
carbon dioxide + water ---> glucose +oxygen
(light)
The statement that correctly describes the process of photosynthesis is that chloroplasts use carbon dioxide, water, and sunlight to produce sugars and oxygen. The correct option is B.
What is photosynthesis?Photosynthesis is the process of producing food, nutrition, and energy. It is done by plants and algae because only they contain chlorophyll. Those organisms containing chlorophyll can perform photosynthesis.
It is a chemical process and the process involves, carbon dioxide, water, and sunlight, and it produces sugar and oxygen as a byproduct. The oxygen is released, whereas the sugar gives the energy.
The process can be described as chloroplast absorbing the sunlight for plants, and the process can only occur in the presence of light or sunlight.
Thus, the correct option is B. The chloroplasts use carbon dioxide, water, and sunlight to produce sugars and oxygen.

4. In transcription, how come the whole DNA molecule is not copied into mRNA?
Answer:
Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template. Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors.
Explanation:
DNA is transcribed into mRNA and this mRNA has the complementary sequence of DNA but is not identical to DNA.
What is transcription?The mechanism for transferring genetic information becomes more complicated if both strands of DNA serve as transcriptional templates.
If both strands of DNA serve as transcriptional templates, dsRNA would be produced, preventing the synthesis of proteins.
Because its sequence is complementary to the DNA template, the mRNA is not an exact replica of the DNA segment even though it includes the same information.
Therefore due to complementary not identical sequences of mRNA during transcription whole DNA molecule is not copied to mRNA.

The Human Body in Space
NASA monitors the bodies of animals and humans to see how they react to extended periods in space. When the body is in space, it no longer has the strong pull of Earth’s gravity on it. Because the body’s systems normally function in the presence of gravity, NASA has been studying the effects of weightlessness on the body.
Weightlessness Takes a Toll
On Earth, the heart naturally pumps blood more forcefully to the upper body than to the lower body, where gravity helps the blood flow down. In space, the heart continues to pump the blood more forcefully to the upper body, but the balancing force of gravity does not pull the blood to the lower body. This uneven blood flow causes astronauts’ faces to become puffy and their lower bodies to become thin.
The shape of the spine also changes in space. Without the force of gravity pushing the vertebrae closer together, the spine stretches out and causes pain in some cases.
Another system affected in space is the body’s balancing system. To balance itself, the brain acquires information from the eyes, muscles and tendons, and a set of sensors (called the vestibular apparatus) in the inner ear. In space, the only balancing information that can be relied on enters through the eyes, so astronauts have difficulty moving around.
The most serious problem for astronauts, however, is bone loss. In space, the bones lose minerals, such as calcium, potassium, and sodium. The bone loss in the legs can be as high as ten percent, and even exercise does not completely solve the problem.
Laboratory in Space
With the completion of the International Space Station (ISS), NASA will be able to study some of the effects of long-term exposure to weightlessness. NASA also plans to expand its studies to better understand how the immune system is affected and how radiation, which is much greater in space,
affects humans. Radiation can pose serious health threats, including cancer and neurological damage.
Because people working together on the ISS will be in small spaces for long periods of time, NASA also plans to study how working in confined spaces affects astronauts’ personalities.
Infer What does NASA expect to gain by studying the effects of long-term space travel on the human body?
Answer:
Knowledge gained during the early years of human spaceflight indicated an adaptation to the new environment. While the empirical evidence was limited, the biomedical data indicated that microgravity alters the musculoskeletal, cardiovascular, and neurosensory systems.

Explain the function of enzymes and how enzymes
can be denatured.
Answer:
They speed up chemical reactions and are denatured by high temperatures and high pH.
Explanation:
Enzymes speed up chemical reactions. They have specifc conditions that allow them to work effectively. Temperature and pH affects how enzymes work. The optimum temperature is the temperature at which enzymes will function best. In most instances they are around 37-40°C (in the human body). Temperatures above this will denatured (destroy) the enzymes therefore they cannot do their task. At Temperatures below the optimum temperature the enzymes activity is decreased to the point where they may not be active.
Optimum pH is the pH at which the enzymes works best. These vary based on the type of enzyme. Any pH above the optimum will denatured the enzymes (destroy). pH below the optimum will decrease the ezymes activity to the point where they may not be active

What is fracking fluids?In order to enhance the amount of hydrocarbons that may be extracted, drilling operations use fracking fluid (also known as frac fluid). The fluid stops the well from corroding. Among other things, it prevents blockages, bacteria from growing, and lubricates the extraction process.
In summary, the chemical composition varies from well to well and is complicated. Depending on the exposure amount, several of these substances can be dangerous to human health.
According to estimates from the oil and gas sector, chemical additives only make up about 1%.
Therefore, It destroys animal habitats and causes topsoil to erode- deforestation 2) pollutes groundwater with dangerous chemicals- injecting fracking fluids into the ground 3) harms aquatic creatures and vegetation- oil spills during transport on a ship.

describe a specific exmaple of postive action that reduce human imapct on land?
Answer:
Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and out-going infrared (thermal) radiation that are part of Earth’s energy balance. Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. Since the start of the industrial era (about 1750), the overall effect of human activities on climate has been a warming influence. The human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruptions.
