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.
How would the finch populations on these islands change over time?
The finch population's beaks will be modified; on dry islands, they will have larger beaks, while on rainy islands, they will prefer medium or short beaks.
What is natural selection?Natural selection is an evolutionary mechanism. Organisms that are better adapted to their surroundings are more likely to survive and pass on the genes that helped them thrive. Species change and diverge as a result of this process.
Because of the differences in environmental conditions, the finch populations on the dry and wet islands are likely to change differently over time.
Finches with traits that allow them to efficiently extract nutrients from dry seeds would have an advantage on the dry island, where food and water resources are limited.
Natural selection would favour these traits over time, increasing the frequency of these advantageous traits within the dry island finch population.
Thus, this way, the finch populations on these islands change over time.

In 100 words or more, explain the role natural selection plays in causing biological resistance.
Plz help
Answer:
The ability of a microorganism to tolerate the effects of an antibiotic is known as antibiotic resistance. It's a certain kind of drug resistance. Antibiotic resistance develops naturally through random mutation, but it can also be engineered by putting a population under evolutionary stress. Bacteria will then transmit genetic information in a hominid-like manner once such a gene has been formed. Following the development of such a gene, bacteria may use plasmid exchange to transfer genetic information horizontally (between individuals). Multiresistant bacteria, also known as superbugs, carry several resistance genes. the reasons for it Transformation protocols can also be used to incorporate antibiotic resistance into a microorganism. This may be a good way to get artificial genes into a microorganism. Antibiotic tolerance is a product of natural selection in evolution. Antibiotic activity is a type of environmental pressure; bacteria that have developed a mutation that allows them to survive will continue to replicate. They will then pass this trait on to their children, resulting in a generation that is completely immune.

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.

6. Which of the following is NOT true of the excretory system? a. Kidneys remove waste from the blood b. Removes waste from sweating c. Excretes feces d. Excretes urine
Kidney waste from sweating is not true of the excretory system.
The correct answer is option B.
What does the excretory system do?The principal function of the urinary system is to maintain the volume and composition of body fluids within normal limits. One aspect of this function is to rid the body of waste products that accumulate as a result of cellular metabolism, and, because of this, it is sometimes referred to as the excretory system.
What are the parts of the excretory system and their functions?The primary excretory organs in the human body are the kidneys, ureters, and urinary bladder, involved with the creation and expulsion of urine. Through these organs, much of the nitrogenous waste of the body, especially urea, is expelled.
