Julie has been working in the laboratory with a new antibiotic. First, she placed an
antibiotic on a petri dish of bacteria. Then she placed a solution of distilled (plain)
water in the petri dish and observed under the microscope that water moves into the
bacterial cells, causing them to burst. In the control group of bacteria that did not
receive the antibiotic, the cells do not swell or burst. Julie is trying to determine what
organelle must be damaged by the antibiotic to allow for the cell to burst.

Answers

Answer 1

Answer:

contractile vacuole.

Explanation:

Contractile vacuole is an organelle which is damaged from the antibiotic and as a result the cell burst. The main function of contractile vacuole is to regulates the quantity of water inside the cell. If the contractile vacuole is damaged so it does not regulate water required by the cell as a result more water enters inside the cell which results in the bursting of the cell.

Earth with any other period of Earth?

Answers

Answer:

Hadean ("Hades-like") Era. This era began with the formation of the earth from dust and gas orbiting the Sun about 4.6 billion years ago. During this era the surface of the Earth was like popular visions about Hades: oceans of liquid rock, boiling sulfur, and impact craters everywhere, meanwhile, during, for example, the Cretaceous period, Earth's land assembled essentially into two continents, Laurasia in the north and Gondwana in the south. These were almost completely separated by the equatorial Tethys seaway, and the various segments of Laurasia and Gondwana had already started to rift apart, and there were oceans of seawater, teeming with life such as Mosasaurs and Ammonites. During the Cretaceous period, the land was hospitable and warm enough to support large numbers of lifeforms, including the dinosaurs.

Which will increase the rate of a chemical reaction?
adding a catalyst
decreasing the pressure
decreasing the temperature
removing a catalyst

Answers

Answer:

Addition of a catalyst

Explanation:

A catalyst tends to alter the rate of a chemical reaction thereby increasing the rate of the reaction

Adding a catalyst will increase the rate of a chemical reaction. Therefore, option (A) is correct.

What are the functions of catalyst?

A substance known as a catalyst is one that, without being consumed during the reaction, accelerates or reduces the temperature or pressure required to initiate a chemical reaction.

A substance which when utilized in limited quantity in responses changes the pace of a reaction without being consumed in the actual response is known as an impetus and this peculiarity is known as Catalysis.

Without actually participating in the reaction, catalyst is used to speed it up. The reaction rate is sped up by catalyst, but the equilibrium constant remains unchanged.

Explanation:

Scientific models help scientists understand the processes in the natural world by providing simpler representations of those processes.

What are scientific models?

A physical, mathematical, or conceptual representation of facts, data, processes, etc to be used as an aid for understanding the said facts, methods, or data are called scientific models.

These scientific models are used by scientists to comprehend or recognize various processes in our world by referencing their scientific knowledge which helps them to better understand and then explain any observable pattern.

Scientific models need to be consistent with the existing explanations or observations. Scientific models are based on facts but they cannot be considered ultimate facts themselves.

Scientific models can be consensus models, mental models, or expressed models based on their representation.

Therefore, the aid used by scientists to properly understand the natural world by providing simpler representations of those processes is called scientific models.

which reaction is exothermic? a reaction thast asorbs energy from the environment. a reaction that requires an activation energy. a reaction that releases energy into the environment. a reaction that does not involve a change in energy

Answers

An reaction that releases energy into the environment.

The enthalpy change (energy taken in for bond breaking of reactants - energy released for bond forming of products) can be used to determine whether a reaction is exothermic or endothermic. Since an exothermic reaction has a negative enthalpy change, it means it releases more energy than what it takes in. Hence the third statement is correct.

An exothermic reaction is a reaction that releases energy into the environment. Thus, the correct option is C.

What is a Reaction?

A reaction may be defined as a process through which one or more substances known as reactants, are converted to one or more different substances, known as products.

An exothermic reaction shows the negative enthalpy change by which it can be assumed that it releases more energy in the environment as compared to consumption during the reaction.  

Therefore, an exothermic reaction is a reaction that releases energy into the environment. Thus, the correct option is C.

What usually happens when new evidence is discovered that is not already explained in an existing theory? Group of answer choices The existing theory is discarded, and a new theory is developed. Scientists choose sides and either support the existing theory or the new evidence. The theory is adapted to account for the new evidence.

Answers

Answer:

The best answer to the question would be - The theory is adapted to account for the new evidence.

Explanation:

If a piece of new scientific evidence is discovered for an already existing scientific theory that is already not explained in the theory it would be lead to the modification of the theory in order to make the theory so it can explain the newly find evidence.

If the theory can not be modified to fit the new scientific evidence the given theory is rejected ultimately. But more often theories are modified to explain the newer findings.

Thus, the best answer to the question would be - The theory is adapted to account for the new evidence.

What usually happens when new evidence is discovered that is not already explained in an existing theory is that more scientific evidence would be gathered about it.

Needless to say, a scientific theory may be modified and rejected if it cannot be made to fit the new findings; in such circumstances, a more accurate theory is then required

Accepted theories may however, be modified or overturned as new evidence Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more.

Scientific evidence

Scientific evidence is evidence which serves to either support or counter a scientific theory or hypothesis.

Students in a science class were asked to investigate how missing or damaged organelles affect cellular homeostasis for cells found in muscle tissues. Which of the following questions should they ask to determine if these muscle cells are functioning properly? A. At what rate do the ribosomes of the cell need to work to produce enough glucose to meet the high energy needs of the cell? B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? C. At what rate do the chloroplasts of the cell need to capture enough sunlight to meet the high energy needs of the cell? D. At what rate does the cell wall need to break down its carbohydrate structure to meet the high energy needs of the cell?

Answers

Answer:

B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?

Explanation:

Organelles are specific in their functioning and hence, each organelle contributes its own quota to the cell's proper functioning. According to the question, a muscle tissue is being worked on to determine the effect of a missing or damaged organelle on its cell.

Mitochondria are organelles found in all eukaryotic living cells. They are the organelles responsible for the synthesis of ATP (energy) used by the cell as a result of the glucose that gets converted in them during cellular respiration.

Therefore, to determine if the muscle cells are functioning properly, the question that: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? should be asked.

Note that, Chloroplast and cell wall are not found in muscle cells, which is an animal cell. Likewise, ribosomes are not organelles for synthesis of glucose.
