Answer:
1-Ecological succession is the process of change in the species structure of an ecological community over time.
2-Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
3-A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system.

The job of both red blood cells and root hair cells is absorption. Red blood cells absorb oxygen through pulmonary veins and their capillaries in the lungs. Root hair cells, on the other hand, absorb water from the soil and transport them to adjoining cells for photosynthesis purposes.
Clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish are just a few examples of the large variety of organisms that can be found in a coral reef. The coral reef and its inhabitants are suffering due to several factors such as pollution, coastal development, sedimentation and destructive fishing practices. What would be the most likely result if some of the species in the coral reef are destroyed? Other organisms would move into the coral reef area The coral reef would be allowed to flourish without so many fish and plants living in and around it. The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance. The waters surrounding the coral reef will become cool with the decreasing number of organisms living there

Which of the following describes a function of the endoplasmic reticulum within a cell?
intracellular transport
lipid synthesis
protein modification
DNA storage
Answer:
lipid synthesis
protein modification
intracellular transport
This is if you have to pick more than one
Explanation:
Because i got it wrong
The most important function of the endoplasmic reticulum is intracellular transport within the cell but ER also performs other functions.
What is intracellular transport?The Endoplasmic Reticulum transports nutrients from one part of the cell to the other within the cell.
What is Endoplasmic reticulum?The endoplasmic reticulum (ER) is a continuous membrane structure in eukaryotic cells that forms a series of flattened sacs inside the cytoplasm.
There are two forms of ER that are commonly found:-Rough ER, which has ribosomes embedded within its structure, giving it a rough appearanceSmooth ER, which lacks these ribosomes and hence appears smooth.The endoplasmic reticulum (ER) plays an essential role in protein synthesis, folding, modification, and intracellular transport.

which two adaptations of herbivorous enables them to digest cellulose
Answer:
Cellulose Digestion in Herbivores
By means of the symbiotic gut bacteria, cellulose can be digested by herbivores with the help of monogastric digestion. Herbivores are less efficient than ruminants in the case of extracting energy from the digestion of cellulose. Here, cellulose is digested by microbial fermentation.
Explanation:
Their molar and premolar teeth help to crush and grind the food and bacteria present in their caecum help in the digestion of cellulose.
How does herbivorous digest cellulose?Cellulose is a polysaccharide made up of repeating glucose units linked by β-1,4-glycosidic bonds, only herbivores are able to digest this biomolecule.
Herbivores have molar and premolar teeth, this flat molars (back teeth) with rough surfaces, which are used for chewing up tough plant tissues. Ruminants have rumen having bacteria which are enabled animals to digest cellulose.
Inside the rumen of cattle, certain bacteria and protozoans are able to secrete the enzymes, which break the cellulose and convert it into glucose units to provide energy.
Therefore, teeth and bacteria two adaptations of herbivorous enable them to digest cellulose.

The image shows a rain forest ecosystem. The energy from plants, or producers, acts as the starting point of energy in the ecosystem. This energy is transferred to other organisms in the food web. In which two ways is the total amount of energy conserved in the ecosystem?
1.Some energy is transferred to the organisms, and the remaining energy is released into the ecosystem as thermal energy.
2. Bacteria eat the dead bodies of organisms to release the organisms’ stored energy into the atmosphere.
3.Some energy is transferred to the smaller organisms, and the rest is stored in the bodies of larger animals.
4.Some energy is transferred to the organisms, and the rest is released by plants in the form of carbon dioxide.
5.Bacteria eat the dead bodies of organisms, obtain all the energy, and store it in their bodies.
Answer:
3.Some energy is transferred to the smaller organisms, and the rest is stored in the bodies of larger animals.

Which of the following is a true statement?
A. Disruptions in an ecosystem are normal and natural changes.
B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.

5' ends of the pre-mRNA strand in Model 1. Where would i put it??
Answer:
I think the right side is 3 prime and left sde is 5 prime
Explanation:
Because the process of transcription takes place in nucleus so it should be put inside the nucleus.
What is nucleus?In genomics, a nucleus is a membrane-enclosed organelle within a cell that houses the chromosomes.
What is Transcription?The process in which information of a strand of DNA is copied into a new m RNA molecule is known as Transcription.
The enzyme responsible for transcription is RNA polymerase. Transcription start when RNA polymerase binds to a promoter region at the start of a gene directly or through helper proteins. Initiation, Elongation, and termination are the three steps of transcription. Transcription is carried out with the help of enzyme RNA polymerase and some proteins known as transcription factors. Enhancer and promoter sequences are the DNA sequences on which transcription factors attach to initiate the transcription process by directing RNA polymerase to the correct transcription site.The transcription initiation complex is made up of transcription factors and RNA polymerase working together.

what process is responsible for the absence of glucose and amino acids in urine
Answer:
The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron
Selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.
What is selective reabsorption?The selective reabsorption mechanism allows the absorption of different substances including glucose and amino acids in the urine.
This reabsorption occurs after filtration in the capillaries of the urinary system. The filtration and excretion of waste substances are associated with the formation of urea.In conclusion, selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.
