Explanation:
out line three advantage of presence of. membranes in cell organelles
Answer:
Membrane-bound organelles offer several advantages to eukaryotic cells. ... If these enzymes were released in the cytosol, they could chew up the cell's proteins, nucleic acids and lipids, leading to cell death. The membrane surrounding the lysosome keeps those digestive enzymes away from the rest of the cell
Explanation:
Answer:
Membrane-bound organelles offer several advantages to eukaryotic cells. First, cells can concentrate and isolate enzymes and reactants in a smaller volume, thereby increasing the rate and efficiency of chemical reactions.

Explanation:
Living things obtain matter from their environment and release waste back into it. This matter moves in a cycle. Plants use air, water, nutrients, and sunlight to make food and grow. Some animals eat the plants and use their matter to grow. When those animals die, decomposers will grow using the matter from the animals' bodies. The decomposers release this digested matter back into the air and soil. The matter in an ecosystem is recycled. Gases are a type of matter that moves through an ecosystem. For example, oxygen and carbon dioxide are cycled between organisms and the air. The producer in the diagram takes carbon dioxide from the air. It uses this gas and water to make sugar, releasing oxygen as waste. Then the consumer breathes in the oxygen and uses it in its body. It also eats the producer for food, represented as carbon in the diagram. The decomposer takes oxygen from the air and food from the consumer or producer. The consumer and decomposer make carbon dioxide, putting it into the air. When producers use it again, the matter is recycled. Describe in words how carbon and oxygen move through an ecosystem. (my little bro needs help and I am to lazy to do it)
Answer:
"living things obtain matter from their environment and release waste back". plants use carbon dioxide, then let out oxygen for us to use. When animals die, decomposers release the digested matter back into the air and soil. Different types of gases move throughout a ecosystem and is recycled between organisms and air. (again going back to the air recycled between a plant and a human).
Answer:
the decomposers release carbon dioxide that help plans grow then they can do photosynthesis then the oxygen is given to animals then they die then decompose and that's a cycle

many pathogenic bacteria species are bcoming resistant to antibiotics. explain how such adaptions can develop through the process of natrual selection
Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. ...

Which of the following patterns in the fossil record would be an example of an organism evolving through punctuated equilibrium?
A. dorsal fins appearing, disappearing, and reappearing in species of ancient aquatic reptiles, mammals, and fish
B. a species of flower changing in shape, followed by a change in the beak shape in its preferred species of pollinator
C. the shell shape of a species of snail remaining unchanged for millennia until it changes to an entirely different shape
D, whale species gradually changing from land-dwelling mammals that walked on four legs to marine mammals without legs
Whale species gradually changing from land-dwelling mammals that walk on four legs to marine mammals without legs would be an example of an organism evolving through punctuated equilibrium. So, the correct option is (D).
What is Punctuated equilibrium?Punctuated equilibrium is defined as the theory that proposes that once a species appears in the fossil record, the population will be stable, showing little evolutionary change for most of its geological history, with little or no morphological change. The condition is called statis.
This balance is the idea that evolution is rapid rather than following the slow, but steady path Darwin suggested. Long periods of stagnation with little activity are interrupted by intermittent bursts of activity in the case of extinction or emergence of new species.
Thus, Whale species gradually changing from land-dwelling mammals that walk on four legs to marine mammals without legs would be an example of an organism evolving through punctuated equilibrium. So, the correct option is (D).

Monitoring a population's age structure plays an important role in successful wildlife management. Which of the following scenarios can be an indicator of overexploitation in fish?
A)
fish catch not reaching older ages
B)
decline in fish catch
C)
both a and b
D)
none of the above
Answer:
d none of the above
Explanation:
because the answer is not one of the a,b,c,d
Answer:
C) both a and b
Explanation:
You're exploiting fish by catching them at a young age. A decline in fish catch can be a consequence of fish exploitation.
A student has two beakers (Beaker X and Beaker Y) of clear unknown liquids. The student knows that one liquid is a weak acid and one is a weak base. She knows that both liquids are equally concentrated as either an acid or a base. The student also knows that the pH of the liquid in Beaker X is 8. Therefore, the student concludes that Beaker X contains the acid and Beaker Y contains the base.
1) State whether or not the student’s conclusion is correct.
2)Explain your answer.
3)Describe the likely outcome in terms of acids, bases, and buffers, if the liquids in
Beaker X and Beaker Y were combined.
Answer: Y E S
Explanation:
A weak conjugate acid-base pair, which can be either a weak acid and its conjugate base or a weak base and its conjugate acid, must make up a buffer in order to maintain a pH range properly.
What is meant by buffer solution?A buffer is a substance that can withstand a pH change when acidic or basic substances are added. Small additions of acid or base can be neutralized by it, keeping the pH of the solution largely constant.
For procedures or reactions that call for particular and stable pH ranges, this is significant. The pH range and capacity of buffer solutions determine how much acid or base can be neutralized before pH changes and how much pH will vary.
A weak conjugate acid-base pair, which can be either a weak acid and its conjugate base or a weak base and its conjugate acid, must make up a buffer in order to maintain a pH range properly. The pH that is desired while making the buffer will simply determine which should be used.
1) As the pH of beaker X is 8 it must be base, the student's conclusion is not correct.
2) Acidic pH values are those below 7, while alkaline pH values are those above 7 (basic).
3) If the liquids combine they create a buffer solution as a buffer exists made by combining a large volume of a weak acid or weak base with its conjugate.

In recent scientific history, the classification of the protist kingdom has changed several times. They are now grouped to consider their development over time instead of simply by what they look like or how they move. Which statement best describes the reason for these classification changes?
A. Traditional scientists did not have enough information about protists to attempt to clasify them.
B. Originally, scientists drew inaccurate conclusions about the classification of protists based on flawed data.
C. Changes in classification of this kingdom are made each time modern scientists discover a new species of protists.
D. The classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms.
Answer:
D
Explanation:
The statement that best describes the reason for these classification changes is the classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms. The correct option is D.
What are the characters of the protist kingdom?All eukaryotes that are not fungi, animals, or plants are collectively referred to as protozoa. It is a tremendously diverse group of species as a result.
Beyond a rather straightforward organizational structure, the eukaryotes that make up this kingdom, Kingdom Protista, do not share many characteristics.
Therefore, the correct option is D. The classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms.

Are all animals that share a food source classified in the same trophic level
ANSWER QUICK PLEASE!!!
Answer:
it depends on the food web that the animal is on but they can sometimes
Explanation:
Answer:
An organism may not always occupy the same trophic level, depending on the food web. Assigning organisms to trophic levels isn't always clear-cut. For instance, humans are omnivores, meaning they can eat both plants and animals. So they may be considered both primary and secondary (or even higher!)
