Answer:
so they can do scientific stuff in there cells
Numerous scientists contributed to the development of the cell theory since it required the cooperation of numerous researchers to acquire evidence from various disciplines of study.
A key idea in biology is the cell theory, which holds that all living things are made up of cells. It began to take shape as microscopy and biological knowledge advanced throughout time.
Numerous scientists, including Rudolf Virchow, Matthias Schleiden, Theodor Schwann, and Anton van Leeuwenhoek, performed important roles.
Thus, these scientists' broad knowledge in fields like microscopy, botany, zoology, and medicine enabled them to put together a thorough understanding of cells, which led to the development and improvement of the cell theory.

Your friend says the following to you: "The lungs are the main part of the respiratory system. You really don't need the rest of the other organs [in the respiratory system]." Prove this to be a false statement.
Answer:
This statement is false because the respiratory system includes muscles that power your lungs. These muscles work together to move oxygen through your body and it cleans out waste like carbon dioxide.
The respiratory system also allows us to speak and smell. So we clearly need all of the organs in our respiratory system.
Answer: This statement is false because the respiratory system includes muscles that power your lungs. These muscles work together to move oxygen through your body and it cleans out waste like carbon dioxide.

Explain how deep currents form and move in the ocean.
Use complete sentences.
This is science 6th grade. Amplify.
Deep ocean currents are formed by differences in water density, which are usually caused by differences in temperature and salinity. The density of seawater increases as the temperature decreases and the salinity increases. This means that colder and saltier water is denser and sinks to the bottom of the ocean, while warmer and less salty water is less dense and rises to the surface.
These differences in water density set up a circulation pattern in the ocean known as thermohaline circulation. In this circulation, cold and dense water sinks in the polar regions and flows towards the equator, where it slowly rises to the surface. This creates a global conveyor belt of deep ocean currents that circulate water around the world's oceans.
The movement of deep ocean currents is also influenced by the Earth's rotation and the shape of the ocean basins. The Coriolis effect, which is caused by the Earth's rotation, deflects deep ocean currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The shape of the ocean basins also influences the movement of deep ocean currents, as currents tend to flow around the edges of the basins and are deflected by land masses and underwater ridges.
Overall, deep ocean currents are an important part of the global ocean circulation system and play a crucial role in regulating Earth's climate by transporting heat and nutrients around the world's oceans.

What is the ethical value of using a model organism, such as zebrafish for doing marine research on pathogens?
The organism can prevent diseases from being transmitted from one species to another, thereby reducing fish mortality.
The organism is immune to all diseases, so the effectiveness of new treatments can be studied over long periods of time.
The organism produces chemicals that can be extracted for use as antibiotics, so they are economically important.
The organism shares its physiology with humans, so testing of new drugs can be done without hurting people.

Why it was important that Gregor Mendel used thousands of pea plants in his experiments? Would Mendel have found the same results if he had used only twenty plants? Explain.
Answer:
Explanation:
Gregor Mendel used thousands of pea plants in his experiments to ensure that his results were accurate and reliable. By using a large sample size, he was able to reduce the effects of chance and random variation in his experiments. This is important because biological systems are complex and variable, and small sample sizes can lead to inaccurate or misleading results.
Mendel's experiments involved crossing pea plants with different traits (e.g., tall vs. short, yellow vs. green), and he counted the number of offspring with each trait. He found that the offspring followed predictable patterns of inheritance, which he summarized in his laws of inheritance.
If Mendel had used only twenty plants in his experiments, he may not have obtained the same results. With a small sample size, chance events can have a greater impact on the results. For example, if he crossed two pea plants with different traits and obtained only a few offspring, it's possible that chance events (such as mutations or environmental factors) could have influenced the results. This could lead to false conclusions about the inheritance of the traits.
Therefore, using a large sample size was critical to Mendel's success in developing his laws of inheritance. It allowed him to detect patterns that were consistent across many different crosses, and to demonstrate that these patterns were not the result of chance variation.

1. How can hanging clothes reduces the greenhouse gas emissions?
2. What is carbon footprint?
3. What is the difference between finite and infinite?
4. How does using a fan lowers the greenhouse gas emissions?
5. What is mitigating?
6. How can sweeping minimizes noise pollution?
7. How does planting can conserve our natural resources?
Answer:
Explanation:
1) Hanging clothes to dry reduces electricity use and greenhouse gas emissions and makes clothes last longer.
2) The carbon footprint serves as an indicator to compare the amount of greenhouse gases emitted over the entire life cycle from the production of a good or service along the supply chain to its final consumption
3) The word 'Finite' itself describes that it is countable, and the word 'Infinite' means it is not finite or uncountable.
Answer:
Explanation:
1.) Using hanging clothes instead of using any machine(dryer) reduces the emission of gases and uses natural ways (sunlight, wind) to dry them up.
2.) Carbon footprint can be defined as the amount of greenhouse gases especially carbon dioxide (CO2) and methane emissions, that relate to daily human activities.
3.) If the no. of elements are countable then they are said to be finite, while if the no. of elements are uncountable then they are said to be infinite.
4.) Fans help to evaporate moisture from the skin, providing a cooling effect as it creates breezes instead of cooling it, while
Air conditioners remove heat from the air by using energy-intensive refrigeration cycles,
Thus fan helps to reduce greenhouse gas emissions.
5.) Mitigating refers to the act of reducing or minimizing the negative impacts of a particular issue or problem.

What is a parasitic relationship?
A parasitic relationship is a sort of symbiotic relationship between two species in which the parasite benefits at the expense of the host while the host benefits from the parasite's presence. Living on or inside the host provides the parasite with nourishment, protection, and other resources for survival, development, and reproduction. In the meantime, the host suffers because the parasite frequently disrupts the host's tissues, organs, or other essential processes, which can result in diminished fitness, illness, or death.
Answer:
A.k.a Parasitism.
It's a sort of symbiotic relationship between two organisms, where a parasite is living off a host, but the parasite benefits, and the host is mostly harmed.
The parasite receives its nourishment and shelter from the host though it's in the parasite's best interest not to kill the host. In turn, the parasite relieves the host from certain diseases or allergies due to parasitic infections which may have protective effects.

balanced, which means that the forces pushing the rock in one direction are equal to the forces pushing the rock in the opposite direction. This is why the rock remains motionless on the flat sidewalk.
Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.
