Explanation:
What happens when the thin filament in a muscle fiber slides over the thick filaments?
Answer:
As the thin filaments slide inward, structures called Z-discs come toward each other and the sarcomere shortens but the lengths of thick and thin filaments do not change. The sliding of the filaments and shortening of the sarcomere cause shortening of the whole muscle fiber and ultimately the entire muscle.
Answer:
Sliding of the filaments and shortening
Explanation:
As the thin filaments slide inward, structures called Z-discs come toward each other and the sarcomere shortens but the lengths of thick and thin filaments do not change.

3. Quantitative data uses numbers to Measure observed changes. How could this experiment be modified so that quantibtive data could be collected to show that water diffused into the dialysis bag?
CAN ANYONE PLEASE ANSWER!!
Answer:
Mass the bag before and after its exposure to the solution. If diffusion occured, then there should be an increase in the bag's mass.
Explanation:
please mark brainlyest
To modify the experiment to collect quantitative data showing that water diffused into the dialysis bag, you could measure the change in the weight of the dialysis bag before and after the experiment.
Here's how you can do it: Prepare the dialysis bag and fill it with a known volume of a solution. For example, you could fill the bag with 100 mL of a sugar solution. Weigh the dialysis bag using a balance before placing it in the beaker with water.
Place the filled dialysis bag into a beaker of pure water. Make sure the dialysis bag is fully submerged in the water. Allow the setup to stand for a specific amount of time (e.g., 1 hour) to allow water to diffuse into the dialysis bag.
After the specified time, carefully remove the dialysis bag from the beaker of water and gently pat it dry with a paper towel to remove any excess water on the outside. Weigh the dialysis bag again using the same balance.
Calculate the change in weight of the dialysis bag by subtracting the initial weight from the final weight. The weight difference represents the amount of water that has diffused into the dialysis bag.

Answer:
The answer would be B,
Explanation:
Increased size of gray areas is the change over time in the landsat maps that would most likely be associated with the contaminated water habitats nearby. Thus, the correct option is B.
What are Landsat maps?
Landsat is a moderate spatial-resolution imagery which provides the large areas of repeated data coverage at a scale that enables the users to see the detailed human-scale processes, such as urbanization, but not the individual houses.
The Landsat series of Earth Observation satellites have continuously acquired images of the Earth's land surface, which provides uninterrupted data to help the land managers and policymakers to make informed decisions about the natural resources and the environment. The increase in the gray areas in the landsat maps is associated with the water contamination.
Therefore, the correct option is B.

What is narcolepsy ?Narcolepsy is a type of sleeping disorder is characterized by severe and persistent daytime sleepiness which can cause impairments in school, work, and social settings.
Narcolepsy affects hundreds of thousands of Americans both children and adults, the symptoms include excessive daytime sleepiness (EDS), where the brain is unable to regulate wakefulness and sleep.
Other symptoms are rapid eye movement (REM) sleep, this sleep irregularly begins within minutes after falling asleep.
It can be up two types Types such as narcolepsy type 1 (NT1) and type 2 (NT2); NT1 is associated with cataplexy, which means sudden loss of muscle tone.
NT1 can be diagnosed with the low levels of hypocretin-1; NT2 was otherwise known as narcolepsy without cataplexy do not have cataplexy or low levels of hypocretin-1.

Four students are discussing heat, thermal energy, and temperature. Claire says temperature indicates the amount of heat in an object. Hazel states that heat is a transfer of energy. Connor says that, if two objects have equal masses, the hottest object has the most thermal energy. Evan disagrees. He says that, if two objects have equal masses, the hottest object has the most heat.
Answer:
Claire and Conner are correct
Explanation:
trust me.....
Among the four students, Hazel and Connor are correct in their statements. Heat is indeed a transfer of energy, as stated by Hazel. Similarly, Connor is right in saying that if two objects with equal masses are compared, the hottest object possesses the most thermal energy. Thus, correct option is (d).
Hazel is right when she says that heat is the thermal energy that is transferred between objects when there is a temperature difference. This is a cornerstone idea in thermodynamics. The claim made by Claire is untrue because temperature really measures the average kinetic energy of an object's molecules rather than the quantity of heat it contains.
The idea that thermal energy, which is connected to the kinetic energy of particles in an object, rises with temperature is supported by Connor's assertion. Consequently, the object with a greater temperature does actually have more thermal energy when two things have equal masses.
Evan's argument against Connor's assertion is unfounded. Temperature measures the intensity of heat, not the overall amount of thermal energy. Therefore, the correct pair of students are Hazel and Connor (option d).

Answer:
The answer to this question is B.) asexual reproduction
Explanation:
Hope this helps :) !!!!!!!!!!!!!!!!!
In asexual reproduction fewer offspring are produced. Asexual type of reproduction is the type of reproduction in which single parent is involved. Thus, option B is correct.
What is asexual reproduction?
Asexual reproduction is defined as the mode of reproduction in which only single parent is involved and in asexual reproduction fewer offspring are produced. There are several types of asexual reproduction and these are binary fission, spore formation, vegetative reproduction, and fragmentation.
Reproduction has been defined as the process that has been carried out by the living organisms and during the process of the reproduction the living organisms produces their own young ones and feed them. Reproduction has the supreme quality of the living things.
There has been two types of the reproduction and these are the sexual as well as asexual reproduction. The process of the reproduction in which two parents has been involved has said to be sexual mode of reproduction and the process of the reproduction in which only single parent has been involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, In asexual reproduction fewer offspring are produced. Asexual type of reproduction is the type of reproduction in which single parent is involved. Thus, option B is correct.

What hypothesis might the experimenter have been testing with this experiment?
Answer Plato:
Increased levels of carbon dioxide cause air to heat up more rapidly.
Answer:
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.
Explanation:
The hypothesis that the experimenter might have been testing with this experiment is increased levels of carbon dioxide cause air to heat up more rapidly.
The experimenter is likely testing whether higher concentrations of carbon dioxide in the atmosphere lead to a faster rate of temperature increase in the surrounding air. This hypothesis is relevant to the study of climate change and global warming, where elevated levels of carbon dioxide, primarily from human activities, are believed to contribute to the Earth's temperature rise due to the greenhouse effect.
In conclusion the experiment would involve exposing air samples to different concentrations of carbon dioxide and monitoring the rate of temperature increase to determine if there's a correlation between CO2 levels and heating rate.

A particular type of potato can only be produced by cloning from it's eyes or budding. Large commercial growers worldwide now plant only this particular type. Some scientists are warning that exclusively growing this type of potato by asexual reproduction presents a serious disadvantage. Why are these scientists concerned?
If an economically important crop such as the potato as highlighted in the illustration can only be produced by cloning, it is normal for scientists to be concerned because a single even of disease attack might end up wiping the entire crop away.
Cloning is more or less mitosis - a division of vegetative cells. In other words, there is no form of genetic recombination in clones. All clones have exactly the same genes as themselves and their parents.
The implication of an entire population of an organism having the same genetic composition is that they will be resistant and susceptible to the same limiting factors - be it biotic or abiotic. Just an event of a disease outbreak might end up wiping all the population away because there will not be any resilience.
