Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.
Explanation:
There are two main reasons why cells divide rather than continuing to grow larger and larger: The larger a cell becomes the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Why does cell division remain important to an adult organism even after it is fully developed? It remains important because cells are renewed and wounds are healed in the process. When cells stop dividing to specialize in structure and function. When cells undergo programmed cell death.

What is the difference between flu viruses and the measles virus?
Answer:Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.
Explanation:
Explanation:
Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.
By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.

Find 2 ways that natural gas forms. List the steps of the two carbon pathways below. Label each location with A for atmosphere, B for the biosphere, G for geosphere, or H for hydrosphere. Use P for the anthroposphere.
Answer:
Biogenic and thermogenic
Explanation:
Biogenic and thermogenic are the two ways or mechanism that is responsible for formation of natural gas. Biogenic gas is formed with the help of methanogenic organisms that is present in marshes, bogs, landfills, and shallow sediments. Thermogenic gas is formed from organic matter that is buried in the deeper earth where the temperature and pressure are very high.
The organic pathway of the carbon cycle is the pathway in which carbon moves from atmosphere, through producers, herbivores and other organisms in the ecosystems, and converted back to the atmosphere.
In geological pathway, carbon moves from the atmosphere, through the ocean to rocks and the mantle, and then back to the atmosphere.

An organism’s adaptations are specific to its native environment. An organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. The following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in Canada, and a tropical rain forest in Belize.
Evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. In your answer, explain the survival challenges that plants face in these two environments.
Coniferous Forest
graphical representations of the temperature and precipitation in a coniferous forest from January to December
Tropical Rain Forest
a graphical representation of the temperature (top image) and precipitation (bottom image) in a tropical rain forest from January to December
Answer:
Ok so one graph shows the temperature it’s in the negative so the plant can’t survive all you have to say is the plant is struggling in the coniferous forest because of the climate there is not enough sun and not enough water the graph next to it shows the amount of water it’s getting and horizontally it’s showing the months and the plants progress the plant is barley surviving and will most likely die vs in the tropical rainforest as you can see the temperature is sunny all throughout the year it’s getting the warmth it needs and the graph next to it is again showing the amount of water it is receiving at first there’s not a lot but pushing more into spring and summer time going farther into colder whether there a lot more rain and because it’s a tropical forest the rain doesn’t turn into snow due with the warm climate it’s the perfect weather for the plant and it easily adapts to this weather because that is the natural environment plants need to grow no matter the plant they all need sun and water I hope that helped this is supposed to be a written out answer you can put it in your own words if you like or use it that way but I just did it and I got a 90% on the grade

Describe at least two ways in which nitrogen is important to biological processes. (Hint: Find the biological chemicals that contain nitrogen.)
Answer:
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food. Nitrogen is a key element in the nucleic acids DNA and RNA, which are the most important of all biological molecules and crucial for all living things. Without amino acids, plants cannot make the special proteins that the plant cells need to grow. Without enough nitrogen, plant growth is affected negatively.

Which of the following answers is NOT correct with regard to convection currents?
A. Convection currents in magma drive plate tectonics.
B.Convection currents in magma are a result of density differences.
C. Convection currents play a role in the movement of Earth’s inner core.
D. Convection currents in magma are caused by temperature differences.
Answer: C....Convection currents play a role in the movement of Earth’s inner core
The statement which is not correct with regard to convection currents is as follows:
Convection currents play a role in the movement of Earth’s inner core.Thus, the correct option for this question is C.
What is Convection current?Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.
The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.
Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.
Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.
Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.
Therefore, the correct option for this question is C.

A student prepares for a five-mile run so she eats a nutritious meal three hours before the run. Which correctly illustrates the transformation of energy from eating the meal to the five-mile run?
Answer: The transformation of energy from eating the meal to the five mile run is from
Chemical energy --> kinetic energy--> thermal energy.
Explanation:
In nature, energy exists in various forms. These forms are inter- convertible, that is, one form of energy can be transformed into another form. Such energy transformations are governed by the laws of thermodynamics.
The first law of thermodynamics states that energy cannot be created or destroyed but may be transformed from one form into another.
Living organisms which comprises the biotic components of an ecosystem are energy converters. For example:
--> plants convert solar energy into chemical energy during photosynthesis
--> animals convert chemical energy into kinetic energy when they move about. This in turn is lost as heat energy when highly complex organised food molecules are broken down.
From the question, the student ate a nutritious meal ( CHEMICAL energy) which is converted to KINETIC energy as she took a five miles run ( as she worked). 'Work' here refers not only to physical activities but also to the various metabolic processes necessary to maintain life. And each time work is done, kinetic energy is converted to heat( thermal energy)

How many times more erosion occurs in a soil with 3% moisture than a soil with 7% moisture is a 15 m s-1 wind?
Answer:
Twice.
Explanation:
If a soil with 3% moisture has twice the rate of erosion as compared to the soil having 7% moisture if both experience same speed of wind i. e. 15 m/s. This is because moisture held the particles of soil tightly with each other and prevent erosion in the soil so if the moisture becomes half in the soil then the rate of erosion is twice or doubled at constant wind speed.

How do living organisms maintain homeostasis within their bodies?
Answer:
The body regulates those levels in an example of homeostasis. When levels decrease, the parathyroid releases hormones. If calcium levels become too high, the thyroid helps out by fixing calcium in the bones and lowering blood calcium levels. The nervous system helps keep homeostasis in breathing patterns.
