Answer:
According to cell theory, all organism arise from the pre existing cell. Cell acts as the structural and functional unit of the living organism. Viruses may be defined as the organism that contain DNA and RNA as their genetic material. Viruses are smaller than bacteria and can affect the different forms of life.
Viruses are non-living as well as acellular organism because they cannot perform the metabolic process that are performed by the living organism. They acts as non - living organism as they do not reproduce, show growth and metabolism outside the host environment. They only shows growth and reproduction once they enter inside the host organism.

Why is it important that farmers plant crops during the winter that improve the levels of nitrogen in the soil?
These crops can fix nitrogen into usable nitrates.
These crops have root nodules that contain bacteria.
These crops produce fruit that quickly decomposes into usable nitrogen.
These crops all use nitrogen in their specialized photosynthesis process.
Answer:
These crops can fix nitrogen into usable nitrates.
Explanation:
There are certain crops which are called cover crops, specifically legumes like peas, vetch,clover and winter field beans . Farmers grow these crops during winter before the growth of actual target crops like cabbage etc which are thirsty for Nitrogen.
What is special about these cover crops is their ability to fix nitrogen into the soil from the atmosphere. There are various ways through which these leguminous crops can fix nitrogen into the soil:
Some legumes like hairy vetch and crimson clover, may fix upto 100 pounds of nitrogen per acre for the utilization by the crop growing in same soil next season.Other legumes like red clover and bigflower vetch can fix from 30 to 80 pounds of nitrogen per acre .Now how the legumes fix nitrogen is through a symbiotic relationship with soil-dwelling bacteria. These are the bacteria that dwell in soil and take nitrogen from atmosphere and provide this nitrogen to leguminous crops through roots which later fix this nitrogen into nitrates.In return, the bacteria can get food in the form of carbohydrates from legumes.This phenomenon confers the leguminous crops with an ability to fix nitrogen in the soil that can be used by the nitrogen requiring crops like cabbage when grown next season in same soil.
Hope it help!
Nitrogen fixation is the process by which nitrogen present in the earth,s atmosphere is converted into ammonia or to the interconnected nitrogenous compounds. Nitrogen fixation is important to life because fixed inorganic compounds are essential for the biosynthesis of the nitrogen containing compounds.
Some plants such as legumes have collaborating relationship with the diazotrophic bacteria which fix atmospheric nitrogen into ammonia. These bacteria contain nitrogenase enzyme whici is responsible for biological nitrogen fixation. The reaction for the nitrogen fixation is as follows
[tex]N_{2} +8H^{+} +8e^{-} -->2NH_{3} +H_{2}[/tex]
The majority of the plants which show symbiotic relationship with the diazotrophic bacteria are legume plants which belongs to Fabacae family.
Since most of the legume plants are grown during the winter season these plants fix nitrogen into suitable nitrates.
Therefore the answer is these crops can fix nitrogen into usable nitrates as most of the legume plants are grown during winter.

Fernanda is working on a physics project. She is experimenting by rolling a marble down a ramp and then seeing how far it rolls along the floor after leaving the ramp.Which would be the dependent variable in Fernanda’s experiments?
The physics project on which Fernanda is working is the rolling a marble down a ramp and observing the distance marble would roll along the floor after leaving the ramp.
Each experiment has an independent and a dependent variable. Independent variable is one whose change is not controlled by the change in another variable or factor. Dependent variable is the one which is measured or determined in any experiment, it varies depending on the changes in independent variable.
In the given experiment, the dependent variable is distance the marble rolls after leaving the ramp as the distance marble rolls depends on the angle at which marble is released on the floor or the material with which the marble is made or the size of the marble. So the independent variable can be any of those, angle at which marble is released on the floor or the material with which the marble is made or the size of the marble.
Answer:
The distance the marble rolls after the ramp
Explanation:
because of the place and directions and the floor place.
what is the relationship between the properties of water and transpiration that takes place in plants?
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. hope this helps and plz friend me im jake and im 13
The process through which the water is released from the plant to the environment is called as transpiration. The water from the root is passed on to the leaf surface through xylem by capillary action of water.
The water exhibits capillary action due to properties such as surface tension, cohesion, and adhesion. With the help of adhesion property, the water molecules binds with the xylem wall molecules, due to cohesion, the water molecules bind with one another and facilitates continuous as well as easy movement from root to the leaf through stem.
The majority of Earth is covered with water. Water takes longer to heat up and cool down which has an impact on the air temperature. The slow change in water temperature is due to water's
to something in the water
This is because of the high specific heat capacity of water.

Which component of the cell membrane functions to actively transport molecules into the cell
The protein component of the cell membrane function to actively transport molecules into the cell.
What is the cell membrane?All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant microenvironment within the cell, and also that membranes serve a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell. Another is that there will be proteins on the cell's membrane, which is its plasma membrane, that communicate with other cells.
These proteins may be lipid proteins, which include both a protein and a fatty acid, or they may be glycoproteins, which contain both a protein and a sugar moiety. Additionally, those proteins that adhere out of the cell membrane enable cell-to-cell communication.
Additionally, a cell's membrane offers some structural support. Additionally, various cell kinds have distinct types of plasma membranes, and the lipid component of the plasma membrane generally contains a lot of cholesterol. This is distinct from a few other membranes found inside the cell.
There are several plants and microorganisms, such as algae and bacteria that have various defense systems. They really have a cell wall surrounding them, which is stronger and more sturdy than a plasma membrane.
Therefore, proteins are the components involved in active transport.

what type of sample can give information on how long someone has been exposed to a poison? Blood Muscle Hair
They would need to give a Blood sample. If someone gives a blood sample, whoever is testing it, can tell a large number of things. (ex. if you're dehydrated, how many red blood cells to white blood cells ratio, if you have a vitamin deficiency, and a ton of other things.) They will be able to tell how long you've been exposed to something poisonous because they will be able to see the changes that the poison has made to the blood stream, and the way it affects it.
Hope this helps!! (:
Final answer:
Hair samples are the most informative for determining how long someone has been exposed to a poison because they encapsulate a chronological record of exposure, unlike blood or muscle tissue which reflect recent exposures.
Explanation:
When it comes to understanding how long someone has been exposed to a poison, hair samples can provide valuable information. As hair grows, substances such as toxins can be deposited in the hair shaft, providing a chronological record of exposure. This is why hair analysis is often used in forensic toxicology when assessing long-term low-level exposure to toxins such as heavy metals, including arsenic, mercury, and lead. Blood and muscle tissues do not provide as clear a historical record of exposure because they are more reflective of recent exposures rather than a long-term timeline.
how does carbonic anhydrase change the reaction between carbon dioxide and water?
It catalyzes the reaction by making it fast (both forward and reverse reactions).
Naturally, the reaction between CO2 and H2O is very slow in the formation of carbonic acid. However, in the blood, due to the presence of the enzyme, the reaction is much rapid by millions of factors. This is because the enzyme reduces the activation energy of the reactants. The enzyme is important in respiration of cells and in pH regulation,
One hypothesis regarding the extinction of dinosaurs is that a meteor hit the earth causing an explosion so powerful that dust blocked out the sun. Consider the model above and explain why would this have caused a mass extinction?
There is no model visible, but the main theory as to how an asteroid/meteor impact would cause a mass extinction is that the force of the projectile landing onto the surface of the earth would launch so much debris and material into the atmosphere that it would block out most if not all light from the sun, leading to a inevitable food pyramid crash. As the producers die and become harder and harder to find, primary consumers decline which leads to the decline of secondary consumers, and so on until you reach the apex predators in the ecosystem(s).

describes one of Isaac Newton's contributions to the world of science
Final answer:
Isaac Newton made monumental contributions to physics, including formulating the laws of motion and the law of gravity, inventing calculus, and improving the theories of light and color, which remain foundational in physical science.
Explanation:
Isaac Newton's Contributions to Science
Sir Isaac Newton (1642-1727) was a pivotal figure in the history of science, making groundbreaking contributions across several fields. His most renowned work, the Philosophiae Naturalis Principia Mathematica, laid the foundation for classical mechanics through his laws of motion and the universal law of gravity. Besides these achievements, Newton invented calculus, which is fundamental to advanced mathematics and engineering, and greatly advanced the theories of light and color, impacting the field of optics.
Newton's laws of motion established a formulaic way to predict the movement of objects both on Earth and in space, marking a significant transformation from the Renaissance to the modern era of thought about the physical universe. This was a move away from the theologically-intertwined science of the past towards a model based on empirical evidence and mathematical precision. Through his work, Newton distilled the Scientific Revolution's findings, building upon the legacies of predecessors like Galileo and Kepler, to provide a comprehensive framework that remains influential in physics today.
Newton's methods and theories emphasized the importance of basing scientific inquiry on observation and experimentation rather than on established authority or solely philosophical reasoning. This approach was integral to the advancement of the Scientific Revolution, setting the stage for the modern scientific method.
