What is thermal pollution?
A( Heat lost to the air and water causing environmental changes
B( Heat used to warm up an area.
C( A bi product of light energy
D( A form of energy
(80 points!)
Answers
Answer: A (Heat lost to the air and water causing environmental changes
Explanation: Simply put, thermal pollution comes from hot water or cold water being dumped into a body of water. Bodies of water naturally tend to dissipate the heat gained from warm currents, underwater hot springs, and from the sun. Thermal pollution is called that because it overwhelms the natural temperature control mechanisms that work in the water.
Answer is letter A-Heat lost to the air and water causing environmental changes

Which of the following is/are true about eukaryotic transcription?
A) RNA polymerases bind directly to the core promoter (TATA box)
B) Transcription factors are required for RNA polymerase ll-dependent transcription
C) RNA polymerase ll transcribes the protein-coding genes
D) Poly-A tail is the last part of transcript synthesis by RNA polymerase ll.
E) rho factor participates in transcription termination
Answers
Answer:
Option B is true (Transcription factors are required for RNA polymerase ll-dependent transcription)Explanation:
Option B is correct because many different transcription factors are involved in the eukaryotic transcription, particularly genes transcribe by RNA polymerase II. TFIID, A, B, F, E, and H are general or basal transcription factors of human.
Option A is wrong because RNA polymerase II first bind with the general transcription factor, TFIID. TFIID recognise the TATA box and forms a platform for TFIIB binding.
Option C is wrong because RNA polymerase II transcribe protein coding genes but it also transcribe small nuclear RNAs (snRNAs).
Option D is incorrect because transcription of poly-A tail is synthesized by template-independent RNA polymerase called poly(A) polymerase.
Option E is also incorrect- rho factor or rho-dependent termination is used by bacterial transcription termination process.

How do animals and plants play a role in the water cycle?
Answers
Answer:
Plants, especially trees, contribute to the water cycle via transpiration, where water evaporates from the surface of their leaves. Close to 10 percent of all water enters the water cycle due to plant transpiration. Animals contribute to the water cycle via respiration, perspiration and urination.
Explanation:
Without the water cycle, freshwater lakes and rivers would not exist and living things would not be able to thrive on land far from the ocean. do not just benefit from the water cycle -- they participate in it. The contributions of living organisms to the water cycle are vital.
Plants, particularly trees, contribute greatly to the water cycle because of the processes they use to . Unlike animals, which get their energy from food, plants convert sunlight into usable energy through photosynthesis. Plants also and through their roots.
When a tree absorbs water, it travels throughout its branches to its leaves. Needed for photosynthesis, trees and plants cannot get the energy they need from the sun without water. During photosynthesis, some excess water from the surface of the leaves, becoming water vapor. The water vapor in the process of travels into the atmosphere and becomes part of the water cycle, in the same way as evaporated water from lakes, rivers and oceans.
At first glance, it may not seem that plant transpiration contributes that much to the global water cycle. But plants and trees supply a large amount of the world's water via this process. About 10 percent of all water enters the cycle via plant transpiration.
Though they don't contribute as much as plants, animals still supply some of the water present in the water cycle. Animals contribute water mainly through , .
When animals breathe, their warm lungs fill with air. Inside the lungs, some of that air condenses into water vapor. When an animal exhales, they release more water vapor than they breathed in, which adds to the water present in the water cycle. Many animals also . When droplets of sweat evaporate from the surface of an animal's skin, they take a bit of the animal's body heat with them. They also turn into water vapor and enter the water cycle, just like water evaporating from plant leaves.
When animals consume water, they to expel the excess, which then then evaporates and re-enters the water cycle. Even animal dung contains some water which may re-enter the cycle in the same way. Though trees represent the biggest living contributors to the water cycle, animals also play a valuable role in recycling Earth's water. Without living creatures, the water cycle’s effectiveness diminishes, and less water recycles. Though often not included in the explanation of the water cycle, all living organisms contribute to it in their distinctive ways.

1. If one body system did not interact with other systems the body would possibly not totally collapse the body it would just affect what you can do and your functions that you could do.
2. If a persons heart rate increases it would benefit the muscular system because the heart puts more blood to the muscles making it stronger.
3. the difference between the left and right side of the heart is that the right receives oxygen-poor blood and pumps it to the lungs while the left pumps the oxygen-rich blood through and to the arteries and other parts.
4. Thats a SUPER broad question.But in layman terms. Muscles are connected to Tendons, When you want to move anything. your muscles will pull on the tendons which pull on a bone.Muscles contracting causes movement. even things where you feel like you’re pushing. its still a muscle pulling, muscles cant push, can only pull (when you “push” its your chest muscles contracting pulling your arm in towards the middle of your body, e.g pushup/bench press).
5. Unlike the small intestine, the large intestine produces no digestive enzymes. Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.
6. The body systems are used to address the basic needs of survival by sending signals differently to different body parts.
