The evolution from vesicles to true cells was best facilitated by the development of (2 points) a membrane separating the cell from its environment organic molecules:______.
a. such as carbohydrates and lipids self-replicating molecules,
b. such as RNA and DNA inorganic molecules,
c. such as nitrogen and oxygen
Answer:
b. such as RNA and DNA
Explanation:
DNA and RNA represent essential molecules present in all organisms. These nucleic acids (DNA and RNA) are composed of large chains of nucleotides that function to synthesize proteins required for cellular processes and to produce cell structures. Both RNA and DNA are highly stable biomolecules capable of storing and transmitting genetic information, which has been a requisite for the evolution of modern cells. Moreover, it is important to note that DNA is a double-stranded molecule and therefore it is more stable than single-stranded RNA.
Answer:
self replicating molecules, such as RNA and DNA

Consider that RR is red (dominant) and WW is white (dominant) plant phenotypes. The offspring of a cross between an RR plant and a WW plant would be pink and white. all pink. all white. red and pink.
Answer:
A, all Pink
Explanation:
Consider that RR is red (dominant) and WW is white (dominant) plant phenotypes. The offspring of a cross between an RR plant and a WW plant would be pink and white. Then the offspring would be pink.
What is dominant plant?Key species that shape how an ecosystem functions are called dominants. Typically, aboveground characteristics are used to evaluate plant dominance.
Individual species, on the other hand, might not scale proportionally belowground compared to aboveground. This is crucial in ecosystems like grassy and shrubby biomes, where the majority of biomass is distributed below ground.
Dominant species are important organisms that influence how an environment works. Typically, plant dominance is assessed using aboveground traits. Individual species may not scale proportionally belowground compared to aboveground, on the other hand.
Therefore, Consider that RR is red (dominant) and WW is white (dominant) plant phenotypes. The offspring of a cross between an RR plant and a WW plant would be pink and white. Then the offspring would be pink.

During strenuous exercise, Max's body produces lactic acid and his blood pH begins to decline. His kidneys go to work to preserve acid-base balance by doing all of the following EXCEPT __________.
a. reabsorbing bicarbonate
b. generating new bicarbonate
c. reabsorbing hydrogen
d. secreting hydrogen
Answer:
c. reabsorbing hydrogen
Explanation:
In this scenario, the individual's kidneys will do all of the following except for reabsorbing hyrdogen. This is because, in a scenario like this where the body pH levels decline the kidneys begin to secrete hydrogen, they do not reabsorb it. It is this process of acid elimination that ultimately causes the body's pH levels to begin rising and restoring themselves to normal. Therefore the answer to this question is c.

An ecosystem experiences a loss of denitrifying prokaryotes. Will this loss affect the health of the ecosystem?
OA. No, because denitrifying prokaryotes do not produce the usable form of nitrogen needed by organisms.
OB. Yes, because an excessive level of usable nitrogen could accumulate and disrupt the ecosystem's balance.
OC. No, because atmospheric nitrogen is not necessary to most organisms in an ecosystem.
D. Yes, because plants and animals will no longer have the usable form of nitrogen that they need to grow.
egion Scor
Answer:
The correct answer is option D. Yes, because plants and animals will no longer have the usable form of nitrogen that they need to grow.
egion Scor
Explanation:
Denitrifying prokaryotes are the organisms that perform the denitrification process in which nitrate is reduce to nitrogen gas in absence of the oxygen with the help of soil microbes such as denitrifying bacteria. It is a essential process that helps in the recycling of nitrogen.
Denitrification can negatively impact global warming by increasing nitrogen gas in environment and losses of nitrous oxide and reducing soil fertility and there would be loss of productivity in agriculture.
Thus, the correct answer is option D.

DeKwami is conducting an experiment in which he needs to use both sucrase and catalase. Which pH should he prepare to ensure that BOTH of the enzymes will show some activity?
Answer:
pH of 6.5
Explanation:
The pH favorable to an enzyme where it is most active is called optimum pH. The optimum pH of sucrase is about 6.0 while that of catalase is 7.0. Both enzymes can however still show some activity when the solution is slightly basic or slightly acidic (from it's optimum pH). Hence, getting the middle point (6+7/2 = 6.5) between the optimum pH of the two enzymes and preparing same will ensure the enzymes show some activity.

Answer:
b. Has risk factors that include atherosclerosis
Explanation:
Ischemic stroke happens when there are underlying factors such as atherosclerosis. Atherosclerosis is caused by clogging of fat and cholesterol in the blood vessels. The reduction in the flow of blood to the brain is usually as a result of blood clumping together and blocking the blood vessels carrying blood to the brain.
The symptoms of ischemic stroke include dizziness, loss of coordination, headache etc.
When both participants in a species' interaction develop adaptations in direct response to one another, this could progress into all of the outcomes except:
Answer:
coevolution
Explanation:
Coevolution refers to the process where two or more species modify each other's evolution via natural selection. Darwin mentioned how insects and flowering plants could coevolve by reciprocal evolutionary modifications. Coevolution has firstly been associated with mutualism between species including, for example, birds and flowering plants. However, coevolution may also involve host-parasite relationships, such as associations involving parasitic organisms and their sexually reproducing hosts. Finally, there are situations where coevolution involves both parasitism and mutualism (i.e., antagonistic coevolution).
The adaptation in direct response to one another could lead to all the outcomes except : Intraspecific interaction ( option 5 )
Intraspecific InteractionIntraspecific interaction is a kind of interaction seen within same species that compete for basic necessities for survival such as food, habitat and water. It does not lead to evolutionary changes within the species, therefore they do not develop adaptations in response to the competition
Hence we can conclude that the adaptation in direct response to one another could lead to all except intraspecific interaction

Answer:
Reinforcement
Explanation:
Reinforcement can be referred to as anything that can be used to increase, enhance or strengthen a desirable behavior in a person or an organism. Reinforcement is of two types, they include positive reinforcement and negative reinforcement. Positive reinforcement has to do with adding a reward in order to enhance a desirable behavior, while negative reinforcement has to do with removing an undesirable thing in order to strengthen a desirable behavior.
From the question asked, because the presence of insects after moving the decaying logs increased the frequency at which the bears moved the decaying logs, the finding of the insects is, therefore, a reinforcement. The finding of the enhanced or strengthened the desirable behavior.

How might you model the relationship between a tomato plant and the hornworm caterpillar? Identify the components of the model, including inputs and outputs.
Answer:
Ok, there are multiple ways of model this, one of the ways can be:
Knowing that a hornworm can strip a tomato plant of its foliage in about two days, we can count the number of hornworms (x, the input) and find the number of plants (y, the output) that they can eat in a day.
So, if a hornworm can eat a plant in two days, then in one day the worm can eat half a plant.
Then:
y = (0.5plants/worm)*x
This says:
The number of plants eaten in one day (y) is equal to half of the number of hornworms
OF course, there are a lot of other ways to model this, for example we can use the time as a variable x, and the number of plants as y.
Knowing that a worm eats a plant in two days:
y = (0.5 plants/day)*x
Now x is the number of days, and y is the number of plants that can be eaten by a single worm

Answer:
The correct answer would be -
Fat produce greater energy than the carbohydrates and protein.
due to the facts fats and proteins both have carbon bonds
Explanation:
Fat have highest number of carbon bonds in comparison of the amount of the carbon bonds present carbohydrate and protein and similarly protein have greater number of carbon bonds
Digestion of the fats provides the most energy per gram, due to the fact that more carbon bonds to break. Protein as well gives the higher energy per gram if compared to carbohydrates.
Thus, the correct answer is -
Fat produce greater energy than the carbohydrates and protein.
due to the facts fats and proteins both have carbon bonds
Answer:
Fat
Explanation: (answer for second part)
The amount of carbon bonds in fat is much greater than the amount in carbohydrates and proteins. Fats give you the most energy per gram, so there must be more carbon bonds to break, thereby releasing more energy.

When you decide whether or not the data supports the original hypothesis, you are.... asking questions asking questions forming a hypothesis forming a hypothesis making observations making observations drawing conclusions
Answer:
drawing conclusions
Explanation:
When a scientist decides if the data collected during an experiment supports the original hypothesis, such a scientist is trying to draw a conclusion from the experiment.
The drawing of conclusion represents one of the significant steps in the scientific method. After observations have been made and hypothesis formulated, the next step is to test the hypothesis through experimentation. Experimentation involves gathering data and at the end of the day, the data are analyzed to see if it conforms with the hypothesis or otherwise.
If the data conforms with the original hypothesis, the hypothesis is accepted as being true, and if otherwise, such a hypothesis is subjected to further testing instead of being accepted.

Calculate the percentage loss of mass between the sucrose solutions 0.1 mol/dm3and 0.5 mol/dm3. Give your answer to three significant figures
Answer:
The percentage loss in mass between sucrose solutions 0.5 mol/dm³ and 0.1 mol/dm³ is 80.0% loss in mass
Explanation:
The molecular formula of sucrose is C₁₂H₂₂O₁₁
The molecular mass of sucrose is 342.3 g/mol
Therefore;
The mass of sucrose in 0.1 mol/dm³ solution = 0.1 × 342.3 = 34.23 g
The mass of sucrose in 0.5 mol/dm³ solution = 0.5 × 342.3 = 171.5 g
The percentage loss in mass of the sucrose is given as follows;
[tex]Percentage \ loss \ in \ mass = \dfrac{Original \ mass - New \ mass}{Original \ mass } \times 100[/tex]
Therefore;
[tex]Percentage \ loss \ in \ mass = \dfrac{171.5 - 34.23}{171.5} \times 100 = 80.04 \%[/tex]
Which gives, the percentage loss in mass between sucrose solutions 0.1 mol/dm³ and 0.5 mol/dm³ is 80.0% to three significant figures.
