In the past, conservationists were concerned with leaving the environment in a better state than the condition he or she found it. The contemporary environmentalism movement, on the other hand, increasingly seems to view humankind as an inherently intrusive interloper upon nature.
Match each energy type with the source uses
Answer:
Geo thermal : Nuclear reactions
Bio mass : plants
Solar : sun rays
Hydro power : Water
Explanation:
Geothermal energy is also used to directly heat individual buildings and to heat multiple buildings with district heating systems. Hot water near the earth's surface is piped into buildings for heat. A district heating system provides heat for most of the buildings in Reykjavik , Iceland.
The major biomass sources currently used are sugar cane and corn to produce bioethanol , and rapeseed for biodiesel production. Other sources are also used such as sunflower seeds, soybean, canola, peanuts, jatropha , coconut and palm oil for biodiesel, and wheat, sugar beet, sweet sorghum and cassava for bioethanol
Conversion of energy from sunlight into electricity
Hydropower or water power is power derived from the energy of falling or fast-running water, which may be harnessed for useful purposes.

Snakes are reptiles that sometimes warm themselves by laying on rocks in the sunshine. Many small rodents live among the cracks in these rocks and use the tiny spaces to hide. The snakes capture and eat the rodents. Which of the following relationships is the LEAST similar to the relationship between the snake and the rodent?
A. a bird eating a worm
B. a fox hunting a rabbit
C. a frog swallowing a flying insect
D. a tick feeding on blood from a deer
It’s D because in all of the other examples, it was a bigger animal eating a smaller one. Not only that, but this is a parasitic relationship rather than predator and prey. A parasitic relationship is when one animal gets benefited, but the other one gets harmed. For example, dogs and fleas.
I hope this helps!
Have a great day!
Stay safe!

A tick feeding on blood from a deer relationship is the least similar to the relationship between the snake and the rodent, hence option D is correct.
What are the characteristics of snake?The rattle of the rattlesnake, which is believed to serve as a warning signal to other organisms. Snakes can regulate the quantity of venom they release, and they can bite either aggressively to get at prey or defensively to defend themselves.
Snakes do not want to squander their limited supply of venom, which they have at their disposal at all times, on nonprey organisms.
Snakes are reptiles that will occasionally lie on rocks in the sun to warm themselves. The cracks in these rocks are home to numerous little rodents, who hide in the confined areas.
Therefore, a tick feeding on blood from a deer is the correct option.

1. A. What is a compound?
1. B.What is one inorganic compound vital
for chemical reactions in cells? What are four groups
of organic compounds important to living things?
2. A.What three important functions does
water perform in cells?
2. B.Suppose a cell is seriously
deprived of water. How might this lack of water affect
the cell's enzymes? Explain.
3. A.Which of the four types of organic
compounds serve as an energy source for cells?
3. B.Which of the four types of organic
molecules contain the element nitrogen?
3. C.An organic compound contains only the
elements carbon, hydrogen, and oxygen. Could this
compound be a carbohydrate? Could it be a protein?
Explain.
Answer:
1a - A chemical compound is a chemical substance composed of many identical molecules composed of atoms from multiple elements held together through chemical bonds. atoms of the equal element bonded in a molecule do not form a chemical compound, in view that this would require two different elements
1b - Inorganic compounds are critical within the body and responsible for many simple functions. The primary inorganic compounds are water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and a few acids , bases, and salts. The body is composed of 60–75% water.
2a - it helps with chemical reactions, cellular form and size and helps the cell regulate temperature.
2b - The chemical reactions vital for life would no longer occur or slow it down.
3a - carbohydrates, lipids, proteins, and nucleic acids
3b - Proteins and nucleic acids
3c - A carbohydrate has only Carbon, Hydrogen, and Oxygen, with the hydrogen and oxygen in the ratio 2:1. A protein is made of amino acids. ... So without nitrogen atoms, the compound cannot be a protein. it can be a carbohydrate, because it contains the elements of a compound. An organic compound contains only the elements carbon, hydrogen and oxygen.

Gregory wanted to know what type of food spiders prefer to eat, so he performed two different investigations.
In one investigation, he observed a spider in his backyard every day for thirty days. He wrote down what the spider ate each day.
In another investigation, he placed the same type of spider in an aquarium that recreated a portion of his backyard environment. Each day, for thirty days, Gregory placed four different items in the aquarium—a leaf, a cricket, a fly, and a beetle. Then, he wrote down which item the spider chose to eat first.
Which investigation produced the most reliable results?
A. Neither investigation would produce useful data.
B. The first investigation would produce more reliable results because it only required daily observation.
C. Both investigations have benefits and limitations and should be examined together to get the most reliable result.
D. The second investigation would produce more reliable results because Gregory was able to control the conditions of the experiment.

What are codons?A segment of three adjacent nucleotides within a DNA or RNA molecule that, when read, denotes the presence of a certain amino acid. There are particular codons that indicate the beginning or end of the translation process. These particular codons are referred to as start, stop, or termination codons.
There are three codons that are referred to as stop codons because they halt the process of translation. These codons are UAA, UAG, and UGA. An amber codon is what's known as the result of a mutation that takes the form of a stop codon but finishes its work prematurely. • The letter AUG is what's known as a start codon, and it's important because it kicks off the translation process.
There are a total of 64 distinct codons, 61 of which specify amino acids and 3 of which serve as termination signals.

What are non-native species?A native species present in ecosystem is the result of only “natural” processes. A non-native species is introduced by human action, either accidentally or deliberately, outside of its natural range.
Examples of non native species includes, Gypsy moth, Nutria, Zebra mussel, etc.
