Testosterone is a small steroid hormone that is important in cell signaling. Which of the following indicates where testosterone enters a cell and why it is able to cross at that point?
А
1, because testosterone is nonpolar and can diffuse through the membrane.
B
2, because testosterone covalently binds to a surface protein and transports into the cell.
C3, because testosterone dissolves in water and flows through the channel
D
4, because testosterone is filtered out of the extracellular fluid and taken into the cell by endocytosis.
<
Answer:
A
Explanation:
explanation is given in answer
Testosterone is a steroid hormone. It is a primary sex hormone. It plays key role in the development of male reproductive tissues such as testes and prostate.
Testosterone is lipophilic signaling molecule. The plasma membrane consist of lipid bilayer so testosterone diffuse through the lipid bilayer and enters the cell.
So, the answer is option A because testosterone is nonpolar and can diffuse through the membrane.
other options-
B because testosterone covalently binds to a surface protein and transports into the cell- incorrect. Testosterone doesn't binds to a surface protein and transports into the cell, it diffuses through the cell membrane.
C because testosterone dissolves in water and flows through the channel-incorrect. Testosterone is nonpolar.
D because testosterone is filtered out of the extracellular fluid and taken into the cell by endocytosis-incorrect. Testosterone is not filtered out of the extracellular fluid and it is not taken into the cell by endocytosis.

Match each example of irony with the type of irony it represents.
1. The reader knows that the boy is about to break up with his girlfriend, but the girlfriend doesn't know.
Dramatic irony
2. Dave's blood pressure medicine game him a heart attack.
Situational irony
3. "Oh, great! I'm so glad it's raining, and I forgot my umbrella."
Verbal irony
ok so...
1. The reader knows that the boy is about to break up with his girlfriend, but the girlfriend doesn't know. That is dramatic irony
because Dramatic Irony appears when the readers know something the character does not know. For example, in scary stories, the reader often knows where the bad guy hides, but the character does not. As the character approaches the hiding spot, the readers may experience heightened suspense due to the dramatic irony.
2.Dave's blood pressure medicine game him a heart attack. That is
Situational irony.
Situational Irony happens when something happens that the reader does not expect to happen. For example, if someone robs a thief in a story, that portrays situational irony. Readers would not expect a thief who robs others to be the one who gets robbed.
3. "Oh, great! I'm so glad it's raining, and I forgot my umbrella." That is Verbal irony
Verbal Irony occurs when a character says one thing but means something else. This type of irony is also known as sarcasm. For example, a parent might reveal verbal irony, or sarcasm, by showing up at the door of an extremely messy room and commenting, "I've never seen your room this clean before! You are grounded." Clearly, the parent revealed sarcasm when commenting about the cleanliness of the room.

Using the weather data in Table 1, create a 12-hour general weather forecast for the next day following the data collected.
Questions and Conclusion
1. Write a summary of the weather that occurred during the 24 hours in Table 1.
2. What are the possible sources of error in the weather data?
3. What relationships do you notice between temperature, dew point, humidity, cloud cover, and air pressure? Provide evidence for these relationships from data in Table 1.
4. In conclusion, how did your graphs support or contradict your 12-hour forecast for the following day?
5. Describe additional data you could collect to make your forecast more reliable.
6. What did you learn about weather forecasting by completing the activity(optional to answer, but an idea for something to write as a response would help)
Explanation:
1. During the day, the earth is heated by the sun. If skies are clear, more heat reaches the earth's surface (as in the diagram below). This leads to warmer temperatures.However, if skies are cloudy, some of the sun's rays are reflected off the cloud droplets back into space. Therefore, less of the sun's energy is able to reach the earth's surface, which causes the earth to heat up more slowly. This leads to cooler temperatures.When forecasting daytime temperatures, if cloudy skies are expected, forecast lower temperatures than you would predict if clear skies were expected.At night cloud cover has the opposite effect. If skies are clear, heat emitted from the earth's surface freely escapes into space, resulting in colder temperatures.However, if clouds are present, some of the heat emitted from the earth's surface is trapped by the clouds and reemitted back towards the earth. As a result, temperatures decrease more slowly than if the skies were clear.When forecasting nighttime temperatures, if cloudy skies are expected, forecast warmer temperatures than you would predict if clear skies were expected.
2. The possible sources of error are human error and misreading the data.
3, As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases. High relative humidity of the air occurs when the air temperature approaches the dew point value.
4. When forecasting if cloudy skies are expected, forecast lower temperatures than you would predict if clear skies were expected.
5. A more reliable approach to weather forecasting is known as the steady-state or trend method. This method is based on the knowledge that weather conditions are strongly influenced by the movement of air masses that often can be charted quite accurately.
6. Weather forecasts are made by collecting as much data as possible about the current state of the atmosphere (particularly the temperature, humidity and wind) and using understanding of atmospheric processes (through meteorology) to determine how the atmosphere evolves in the future

A population of rabbits moves to a dry desert environment. How could natural selection be a main contributing factor to speciation in this rabbit population?
A) Most of the rabbits die due to dehydration.
B) Some rabbits reproduce at a different rate.
C) The rabbits are able to interbreed with other species of hare living in the desert.
D) Some of the rabbits are better adapted to the drier environment.
Answer:
D) Some of the rabbits are better adapted to the drier environment.
Explanation:
Natural selection is when the environment favours certain traits in organisms. Organisms that possess these traits are more likely to survive and pass on the traits to their offspring, leading to evolution.
Speciation is when populations become different enough (for example due to natural selection acting on variation in the population) that new species form.
If some rabbits posses traits that make them better adapted to the drier environment, then these rabbits are more likely to survive and pass on these traits to their babies. Eventually, this can cause speciation, as the rabbits that live in the desert are subject to different selective pressures (drier environment)

Explain how seeds travel. Be sure to give examles to support your explantion psb quic
Answer:
Wind, Water, Animals, and Fire.
Explanation:
Wind moves seeds from one place to another. When the seed gets into the air, it gets pushed by wind to another place. Water moves seeds when seeds fall into water and the water moves the seed downstream, or the water evaporates. Seeds get moved by Animals when, for example, a bird eats seeds then flies to another location, and poops out the seeds. Seeds also get moved by Fire when a forest fire erupts and the seeds fall to the ground after the fire dissipates.

Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?
A)The atoms form a bond with a bond length of 25 pm
B)The atoms form a bond with a bond length of 75 pm
с)The net force between the atoms is attractive at 25 pm
D)The net force between the atoms is attractive at 75 pm
Answer:
A)The atoms form a bond with a bond length of 75 pm
Explanation:
The Morse curve is a plot of potential energy against internuclear distance between two atoms.
When two atoms are far apart, the bond energy is zero, this means that there is no significant interaction between the both atoms. Hence, when two atoms are positioned at infinite distance from each other, they do not interact with each other appreciably. At internuclear distance within the range of atomic diameter, attractive forces predominate between atoms. At shorter distances repulsive forces predominate and the energy of system is quite high. The minimum point in the plot of a Morse curve represents equilibrium between attractive and repulsive forces.
The internuclear distance that corresponds to this minimum point is known as the equilibrium bond length.
For the plot shown in the question, the minimum point occurs at an internuclear distance of 75pm. This corresponds to the bond length of the system.

How are combustion,
respiration, and decomposition similar to each
other?
Answer:
The waste products of carbon dioxide and water are also formed. Combustion, which is the burning of carbon compounds, which are fossil fuels, is often compared to cellular respiration because the two processes are extremely similar. ... It's as if our bodies burn our food for energy.
Combustion, respiration and decomposition are similar to each other because they release carbon dioxide.
Combustion is the reaction that occurs between an oxidizable material and oxygen, which is revealed through flames and generates the release of energy.
The different components that are completely oxidized, gives rise to the formation of liquid water and carbon dioxide and even sulfur dioxide.
Respiration is a gas exchange system with the environment, where a fuel molecule, glucose, is oxidized.
Humans take in oxygen through inspiration and exhale carbon dioxide as a waste product produced by the body.
The decomposition of organic matter is useful for microorganisms for two reasons: as an energy supply for their growth, and as a carbon source for the formation of new cellular material.
Carbon dioxide, methane, organic acids, and alcohols are waste products released in the acquisition of energy.
Therefore, we can conclude that combustion, respiration and decomposition are similar to each other because they release carbon dioxide.
