Science: Ecosystem Passage, Jan. 14, 2022 1. Read the passage about the ecosystems. 2. Answer the questions in complete sentence

s. 3. Use correct spelling and punctuation marks. Ecosystems Name: An ecosystem is a community of plants and animals and the physical environment in which they live. There are many different types of ecosystems. Some examples include Arctic regions, deserts, evergreen forest, rain forests, mountains, and marshes. Earth has many different types of plants and animals, and they are perfectly adapted to live in one of these communities, or ecosystems. The plants and animals of a particular ecosystem depend on that ecosystem for survival. Animals that live in a rainforest could not live in an Arctic region. Animals living in a marsh could not survive in the mountains. When an ecosystem is changed, the plants and animals living there are affected. Cutting down the trees of a rainforest or evergreen forest would not only change the way an area looks, but it would cause huge changes for the plants and animals living there. Imagine The monkeys of a rainforest living in an area with no trees. They could not do so. Monkeys needed trees for hunting, sleeping, transporting themselves from place to place, and safety. Remove the trees from an ecosystem that is made of trees and the plants and animals living there would perish. Marshlands are an ecosystem that consists of water, trees, and tall grass. Remove any one of those from a marsh and all animals living there would disappear. Drain the water from a marsh and the animals and the plants would disappear. With no water, the plants of a marsh would die. With no water, the animals that live in water would die. Animals that hunt for food in and around the water would disappear. Where would they go? Animals used to living and hunting in a wet area would either die or go in search of another wet area in which to live. A marsh could be changed in another way: pollution. Polluting the water of a marsh would cause similar results. Science Standard: S4L1. Obtain, evaluate, and communicate information about the roles of organisms and the flow of energy within an ecosystem. c. Design a scenario to demonstrate the effect of a change on an ecosystem 1.RI. 4.3 Explain why events, procedures, ideas, or concepts,in a historical, scientific, or technical text, including what happened and why, based on specific information from the text Explain what would happen to an animal if the vegetation around them disappeared? 2. RI. 4.3 Explain why events, procedures, ideas, or concepts,in a historical, scientific, or technical text, including what happened and why, based on specific information from the text Explain why animals living in a rain forest could not survive in the arctic. 3.RI.4.2 Determine the main idea of a text What is the passage mainly about? (Short Answer) 4. RI.4.4 Determine the meaning of general academic vocabulary and domain specific specific words Remove the trees from an ecosystem that is made of trees and the plants and animals living there would perish. In the sentence above, what does the word perish mean? A. To grow B. To decay C. To eat D. To see R.L.1 Refer to details and examples in a text when explaining what the text says explicitly and when drawing inferences from the text. 5. Explain what would happen to animals if and when the water disappears? 6.4.RI.5: Describe the overall structure (e.g., chronology, comparison, cause/effect, problem/solution) of events, ideas, concepts, or information in a text or part of a text. Remove the trees from an ecosystem that is made of trees and the plants and animals living there would perish. Cause: Effect:​

How are muscles the contractile specialists of the body?
Mariana [72]
<span>Muscle cells are uniquely adapted to contractile function due to three main things. FIrst, they have a large capacity for storage of readily available glycogen to use for work. Second, they contain the actin and myosin cross-bridge cycling structure to perform a contraction of a muscle fiber. Finally, each fiber has central nervous innervation to control contraction and relaxation of the muscle fibers.</span>

What are the common promoter elements found in eukaryotic genes, and how are they different from enhancer elements?
V125BC [204]

Answer:

In eukaryotic cells you find core and proximal promoters.

Promotors are specific DNA sequences where transcription factors (proteins) and RNA polymerase binds to initiate transcription. Promotors are located upstream the coding sequence

Core promoters are where RNA polymersae binds and proximal promoters are where transcription factors bind.

Enhancer elements are DNA sequences where transcription factors (proteins) bind to increase the rate of expresion of an specific gene. Enhancers can be located either upstream,  downstream or thousands of nucleotids away  from the of the coding region.

Explanation:

Promoters and enhancer are key elements for controling gene regulation. Transcription begins when chromatin rearranges from a condensed state to a accesible state, this allow to transcrition factors and RNA polymerase to  bind specif DNA sequences (promotors).  Proteins bind to enhancers , this complex develops a DNA loop, so that the protein that is bound to the enhancer interacts with the RNA polymersase. When this interaction is made, the activity of the RNA polymerase is increased.
