Answer:
a. Osmosis
b. Diffusion
c. Facilitated diffusion
Explanation:
Mitochondria is the power house of the cell which is responsible for the production of energy from glucose molecules. If they are destroyed, no energy is available for transport of material in or outside of the cell. Only osmosis, diffusion and facilitated diffusion occurs because they are the types of passive transport in which molecules moves from a region of higher concentration to the region lower concentration without the use of energy.
Despite the absence of mitochondria, a cell can still conduct osmosis, diffusion, facilitated diffusion, exocytosis, pinocytosis, and phagocytosis. These processes don't rely on mitochondria for energy as they either use passive transport or acquire energy from the cytosol.
Explanation:In the absence of mitochondria, a cell would still be able to conduct the following transport processes: osmosis, diffusion, facilitated diffusion, exocytosis, pinocytosis, and phagocytosis.
Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Diffusion is the process where particles spread out from an area of high concentration to an area of low concentration. Facilitated diffusion is a type of passive transport that allows substances to cross cell membranes with the help of carrier proteins.
Exocytosis is the process by which a cell transports secretory products through the cytoplasm to the plasma membrane. Pinocytosis is a type of endocytosis wherein the cell takes in extracellular fluids.
Phagocytosis is a process wherein a cell engulfs a solid particle to form an internal compartment known as a phagosome. These processes do not rely on mitochondria for energy as they use passive transport mechanisms, or in the case of endocytosis, energy from the cytosol.

Which of these provides evidence from developmental blology of a shared evolutionary history?
a. the dna sequences of the cytochrome c genes in chimpanzees and spider monkeys are over 90% identical
b. the skeletal structure of a leg of a horse and a flipper of a whale are very similar
c. both snakes and dogs have pelvical bones even though they are vestigial structures of the snake
d. both lobsters and frogs go through metamorphosis as a process in their life cycle
Answer:
b
Explanation:
The evidence from developmental blology of a shared evolutionary history is both snakes and dogs have pelvical bones even though they are vestigial structures of the snake and the correct option is option C.
Snakes and dogs belong to different evolutionary lineages, yet both possess pelvical bones, which are vestigial structures in snakes. The presence of these bones in both species suggests a shared ancestry and evolutionary history.
This indicates that their ancestors once had functional pelvic structures, but over time, snakes lost the need for them and they became reduced and non-functional.
The presence of vestigial structures in different species indicates a common ancestor with a shared developmental pathway, supporting the idea of shared evolutionary history.
Thus, the ideal selection is option C.

5. Marina Silva says, “This is the first time it has happened thanks to the discourse
and activities of the federal government." Her tone can best be described as
O
A. awestruck
O
B. critical
O
C. egotistical
O
D. sentimental
Final answer:
Marina Silva's tone is best described as critical, emphasizing the significant role of the federal government's actions. The traditionalistic political culture refers to the maintenance of the existing social order, and the term sovereignty describes a state's recognition of another state's autonomous power. So the correct option is B.
Explanation:
Marina Silva's tone in the statement, “This is the first time it has happened thanks to the discourse and activities of the federal government,” can most appropriately be described as critical. The context of this statement is not provided in the question, but typically, if someone points out an occurrence for the first time due to government activities, there's an implication that they are spotlighting the role of the government as pivotal and noteworthy, often in a critical or evaluative way. Thus, this likely implies a recognition with potentially a hint of criticism of the government's action or inaction in a given context.
Regarding the question concerning the political culture where the government maintains the existing social order, the correct term would be traditionalistic. In a traditionalistic political culture, there is a maintenance of the status quo, and social and political relationships are characterized by a continuation of what has been historically established.
Regarding social media's impact on governance, the role of social media in organizing events and shaping public opinion has been significant. It has the power to influence politics by allowing information dissemination and organizing at unprecedented speeds, which can contribute to government misjudgment or swift social changes, often catching governments off guard.
In international relations, when a state recognizes another state's sovereignty, it is both exercising and bestowing power. Sovereignty acknowledgment implies respecting the autonomy and self-government of the other state, thereby highlighting a recognition of equal status in the international system.

Earth’s energy is a description of how Earth uses the energy from the Sun as it flows in and out of the Earth system.
Answer:
budget
Explanation:
Explain the difference between a theory, hypothesis, and
law.
Hypothesis
A hypothesis is an educated guess, based on observation. It's a prediction of cause and effect. Usually, a hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven but not proven to be true.
Example: If you see no difference in the cleaning ability of various laundry detergents, you might hypothesize that cleaning effectiveness is not affected by which detergent you use. This hypothesis can be disproven if you observe a stain is removed by one detergent and not another. On the other hand, you cannot prove the hypothesis. Even if you never see a difference in the cleanliness of your clothes after trying 1,000 detergents, there might be one more you haven't tried that could be different.
Theory
A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it. Therefore, theories can be disproven. Basically, if evidence accumulates to support a hypothesis, then the hypothesis can become accepted as a good explanation of a phenomenon. One definition of a theory is to say that it's an accepted hypothesis.
Example: It is known that on June 30, 1908, in Tunguska, Siberia, there was an explosion equivalent to the detonation of about 15 million tons of TNT. Many hypotheses have been proposed for what caused the explosion. It was theorized that the explosion was caused by a natural extraterrestrial phenomenon, and was not caused by man. Is this theory a fact? No. The event is a recorded fact. Is this theory, generally accepted to be true, based on evidence to-date? Yes. Can this theory be shown to be false and be discarded? Yes.
Law
A scientific law generalizes a body of observations. At the time it's made, no exceptions have been found to a law. Scientific laws explain things but they do not describe them. One way to tell a law and a theory apart is to ask if the description gives you the means to explain "why." The word "law" is used less and less in science, as many laws are only true under limited circumstances.
Example: Consider Newton's Law of Gravity. Newton could use this law to predict the behavior of a dropped object but he couldn't explain why it happened.
As you can see, there is no "proof" or absolute "truth" in science. The closest we get are facts, which are indisputable observations. Note, however, if you define proof as arriving at a logical conclusion, based on the evidence, then there is "proof" in science. Some work under the definition that to prove something implies it can never be wrong, which is different. If you're asked to define the terms hypothesis, theory, and law, keep in mind the definitions of proof and of these words can vary slightly depending on the scientific discipline. What's important is to realize they don't all mean the same thing and cannot be used interchangeably.
eh- hope you understand now..
Answer:
A theory is a group of related hypotheses that can be accepted as true based on repeated investigations with similar results. A law is a scientific concept that explains what patterns of behavior will be seen through repeated investigations.

Through the process of photosynthesis, light energy from the Sun was transformed into chemical energy in the form of sugar within a strawberry plant. The strawberries were then eaten by a bird, and the sugars were converted into other essential molecules, such as proteins or fats. When the bird produced waste, bacteria in the soil decomposed the waste into elements, such as carbon and nitrogen, which were recycled back into the ecosystem.
In this example, matter and energy changed forms and locations as they flowed through the ecosystem. What else is true?
A.Matter and energy were lost each time they changed forms.
B.The total amount of matter and energy increased.
C. Matter and energy were lost each time they changed locations.
D. The total amount of matter and energy remained the same.
Answer:
D.
Explanation:
In the given example the matter and the energy both changed the forms and locations but the amount of matter and energy remained the same. Therefore, option d is correct.
How does the energy flow through an ecosystem?The energy flows through the ecosystem from one trophic level to another. It is transferred between organisms in a systematic manner from producers to primary consumers, from primary consumers to secondary consumers, from secondary to tertiary consumers, and finally to decomposers.
In this way, the energy and the matter are circulated and released back into the environment so that they can be reused over and over again. There is a unidirectional energy flow in an ecosystem. The energy moves through the ecosystem and changes form but no new energy is created.

What are three ways body systems work together to maintain homeostasis?
Answer:
Each organ system performs specific functions for the body, and each organ system is typically studied independently. However, the organ systems also work together to help the body maintain homeostasis.
For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water. If the water level gets too low, more concentrated urine is produced so that water is conserved. The digestive system also plays a role with variable water absorption. Water can be lost through the integumentary and respiratory systems, but that loss is not directly involved in maintaining body fluids and is usually associated with other homeostatic mechanisms.
Similarly, the cardiovascular, integumentary, respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body. Rapid breathing can also help the body eliminate excess heat. Together, these responses to increased body temperature explain why you sweat, pant, and become red in the face when you exercise hard. (Heavy breathing during exercise is also one way the body gets more oxygen to your muscles, and gets rid of the extra carbon dioxide produced by the muscles.)

Explanation:
I just got the question lol
Hope it helped!
A collection of creatures that can breed with one another in nature and have healthy offspring is referred to as a biological species, hence option 2 is correct.
What is a species?Generating viable children is dependent on interbreeding. The offspring must be able to reproduce in order to be deemed "viable".
Humans have 99.9% of the same DNA as each other. Additionally, the 0.1% of human DNA that varies from person to person does not neatly fit the definition of the race since biology does not support the idea of race.
Because of this, we are too similar to one another to be classified as separate subspecies.
Therefore, the biological species concept, describes a species as members of populations that may interbreed with one another, hence option 2 is correct.

Note that the evidence shown on the map that indicates point B is most likely experiencing precipitation is the front represented by the line with bumps moving from low to high pressure.
On the map, the indication that point B is likely experiencing precipitation is the presence of a front represented by a line with bumps moving from low to high pressure.
This front typically denotes a transition zone where warm and cold air masses meet, leading to atmospheric instability and potential precipitation. As the front advances, it often brings changes in weather conditions, including cloud formation, rainfall, or other forms of precipitation, affecting areas along its path such as point B.
