If there are 1,000 kilocalories of energy available at the
producer level, how much energy will be available at the 3rd
consumer level?
Answers
Answer:
1 kilocalorie of energy
Explanation:
As you go up from each layer, you divide the amount of energy by 10. (Otherwise known as the Rule of 10)
So if the producer has 1000 kilocalories of energy, the grasshopper would have 100 cause you divide it by 10.
Then from the grasshopper to the mouse, you would divide 100 by 10 to get 10.
And finally from the mouse to the owl, you divide 10 by 10 to get 1 kilocalorie of energy.

Next Sandra tests the hardness of each mineral by scratching it with different materials as shown in the chart. The values in the chart are based on the Mohs Scale of hardness, which ranks the hardness of minerals on a scale of 1 to 10. The harder the mineral is, the higher its rating will be. If the material is harder than the mineral, it will scratch the mineral. For example, according to this scale, if a mineral is unable to be scratched by a steel nail, then the mineral has a hardness greater than 6.5.

Answers
Answer: The Low Pressure systems will usually be found more North where it gets verycold but can really happen anywhere, and High pressure systems are usually found in the Southwest during winter.
Explanation:
High Pressure:A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward. On a weather map, you may notice a blue H, denoting the location of a high pressure system.
Low Pressure:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation. Because of Earth’s spin and the Coriolis effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator. This is called cyclonic flow. On weather maps, a low pressure system is labeled with red L.
How do you think the sequence of amino acids in an enzyme relates to its ability to bind to a specific target molecule?
Answers
Answer:
The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). ... Thanks to these amino acids, an enzyme's active site is uniquely suited to bind to a particular target—the enzyme's substrate or substrates—and help them undergo a chemical reaction.
Explanation:
Enzymes are biocatalyst that accelerates the rate of chemical reaction without itself being consumed. Enzymes are mostly proteins.
The binding of enzyme with substrate is highly specific. A given enzyme usually binds to only one kind of substrate. The substrate binds to the enzyme at the active site.
Active site is the region of an enzyme where the substrate binds. The active site consist of sequence of amino acid residues which is uniquely suited to bind to a specific substrate.

Write a description or a reason why you are doing this activities of conserving our natural resources.

2. Hanging clothes -
3. Walking -
4. Feeding the stray animals -
5. Using back page of paper -
6. Using fan -
7. Watering the plants -
8. Sweeping -
Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

how do creationists and evolutionists differ in their views of natural selection?
Answers
Answer: creationists believe in higher power to create things as is and evolutionists believe we originate from a common past and constantly change
Explanation: Creationists believe the belief that the universe and living organisms originate from specific acts of divine creation, as in the biblical account, rather than by natural processes such as evolution.
The theory of evolution is based on the idea that all species are related and gradually change over time. Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism.
Answer:
Creationists believe that natural selection is a God ordained process. Evolutionists believe that natural selection is a scientific process.

Why do your fingers look like prunes after swimming for a long time?
Answers
Answer:
pruney fingers are caused by shrinking blood vessels. When you soak in water, your nervous system sends a message to your blood vessels to shrink. Your body responds by sending blood away from the area, and the loss of blood volume makes your vessels thinner.
Answer:
This is because when you swim in a pool for a while your hand seem to be pruney and it is because when the hand is soaked in water, the nervous system sends a message to the blood vessels in your hand to shrink.

Answers
Answer is homeostasis
Explanation:
Homeostasis is the stable point of a cell
is the state of steady internal, physical, and chemical conditions maintained by living systems.This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.
