i need someone to answer this quick please!! the question is looking at this picture, how does the energy change throughout the pyramid? Is there the same amount of energy at each level? please be specific and no one word answers
Answer:
In these Trophic Levels, Ten percent of energy is being passed up from one trophic level to another. Suppose, 10 percent of energy is being passed up from primary producers to primary consumers. Then, again, 10 percent of energy is being passed up from primary consumers to secondary consumers. the rest 90 percent of energy is used for metabolism, excretion, etc. Since producers produce their own food, the Suns energy is being passed down to the producers which are autotrophs. Since, Heterotrophs like the consumers can't produce their own food due to not being able to photosynthesize, The consume 10 percent energy from each trophic level going up
This is an trick question what is there but you can't see it
13. As a direct result of the life process called
cellular respiration in humans,
(1) liquid wastes are eliminated from the body
(2) food is digested and absorbed into the blood
(3) energy is released from digested food within
the cells
(4) nutrients are transported within the cells
Through cellular respiration, cells use organic compounds taken from food to produce energy. Option (3) energy is released from digested food within the cells.
What is cellular respiration?
Cellular respiration is the process by which cells degrade organic compounds and turn them into energy.
Cellular respiration follows two ways, aerobic and anaerobic respration, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
In human, occurs aerobic cellular respiration.
1. Occurs in the presence of free oxygen.
2. Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
3. Respiration occurs in the mitochondria.
4. Takes place in two steps or stages: Krebs cycle and electron transporter chain.
5. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
According to this framework, the correct option is (3) energy is released from digested food within the cells.

We used different color to stain different chromosomes: orange for Christine X yellow for Christine y green for Christine 13 blue for chrose 18 and red for chromosome 21. Based on the slide analysis do you think that the baby would have any Christine abnormaity?
If the newborn possesses a pair of sex chromosomes, it would be able to identify the sex of the child based on the chromosomes' staining colors.
The child is thought to have one chromosome X and one chromosome Y, the sex chromosomes that determine male features, according to the colors used in the analysis. A person's sex is determined by a pair of chromosomes called the "sex chromosomes." In humans, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). Consequently, the baby would be male.
Therefore, the correct option is A.

What is one likely result of protecting environmental resources for future generations
Answer:
Our environment supports and houses our ecosystems, allowing them to grow and thrive. If we fail to protect our environment, we will put the lives of humans, animals, plants and more at risk.
Why is it important to preserve natural resources for future generations?
Conservation is the practice of caring for these resources so all living things can benefit from them now and in the future. All the things we need to survive, such as food, water, air, and shelter, come from natural resources. Some of these resources, like small plants, can be replaced quickly after they are used.
How do environmental problems affect the life of the future generation?
Children's immune systems are still developing, leaving their rapidly growing bodies more sensitive to disease and pollution. Extreme events can destroy homes, schools, childcare centers and infrastructure critical to children's well-being. Droughts and flooding can destroy crops and cut access to clean water.

Answer:
One likely result of protecting environmental resources for future generations is that it will help mitigate the effects of climate change and preserve biodiversity. According to the web search results123, protecting environmental resources such as forests, wetlands, oceans, and soil can reduce greenhouse gas emissions, enhance carbon storage, prevent land degradation, conserve water resources, and support the survival of various species of plants and animals. This can benefit not only the future generations but also the current ones by improving their health, well-being, and livelihoods. Protecting environmental resources for future generations also requires sustainable use and management of natural resources, which can foster innovation, efficiency, and cooperation among different stakeholders

What are 3 activities that release carbon dioxide into the atmosphere?
Answer:
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
What are the top 3 human activities that produce CO2?
Eighty-five percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil, including gasoline. The remainder results from the clearing of forests and other land use, as well as some industrial processes such as cement manufacturing.
What causes carbon dioxide to increase in the atmosphere?
Human Activity Is the Cause of Increased Greenhouse Gas Concentrations. Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

help please! we have to look at the pyramid and create a claim about how we think energy will change and if there is the same amount of energy at each level
Answer:
As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller. While energy can not be created or destroyed is it released as heat within each level. Approximately only 10% of energy is passed from one level to the next.

Describe the roles of B and T cells in providing immunity for a specific viral disease
B and T lymphocytes protect against viruses.
B cells produce antibodies that neutralise virus particles. B cells triggered by viruses create high amounts of virus-specific antibodies. These antibodies neutralise the virus, preventing it from infecting healthy cells.
T lymphocytes kill infected cells directly. They destroy virus-infected cells before they spread to healthy ones. T cells also stimulate and coordinate the immune response to target the viral infection. B and T lymphocytes cooperate to fight viruses.

Which of the following explains why nuclear energy is nonrenewable?
SEV3.a (MC)
Which of the following explains why nuclear energy is nonrenewable?
a There is a finite amount of hydrogen.
b There is a finite amount of uranium.
c Nuclear fusion can only happen seldomly
d Nuclear fission can only happen seldomly.
The nuclear energy is nonrenewable because b. There is a finite amount of uranium.
Nuclear energy is generated by nuclear reactions, either nuclear fission or nuclear fusion. Nuclear fission is the process where the nucleus of an atom is split into two smaller nuclei, releasing a large amount of energy. Nuclear fusion is the process where two atomic nuclei are combined to form a heavier nucleus, also releasing energy.
While the fuel for nuclear power plants is primarily uranium, which is abundant on Earth, it is still considered nonrenewable. This is because there is only a finite amount of uranium available on Earth, and once it is used up, it cannot be replaced. While there are efforts to extract uranium from seawater and other unconventional sources, it is still not considered a renewable resource.
The finite nature of uranium reserves is the main reason why nuclear energy is considered a nonrenewable source of energy.
Therefore, the correct option is b There is a finite amount of uranium.
