Answer:
Break down lignin.
Explanation:
The continual slow degradation of the phenolic portions of lignin (humic acids) provides a long-term supply of nutrients to plants. Phytoplankton (the primary producers in aquatic systems) do not synthesize appreciable amounts of lignin, and so fungi are not necessary to decompose it!

a skeletal muscle generates the greatest tension when it is:
Explanation:
A skeletal muscle generates the greatest tension when it is: partially stretched before being stimulated
Skeletal Muscle generates the greatest tension when the muscle is stretched to an intermediate length, by length-tension relationship.
How tension generates in skeletal muscle?Muscle tension is highest in skeletal muscles when stretched to an intermediate length, as indicated by the length-tension relationship.
When skeletal muscle fiber contracts, myosin heads link to actin to create cross-bridges, and the thin filaments slide across the thick filaments as the heads pull the actin, resulting in sarcomere shortening and muscular contraction stress.
The amount of stress produced by a muscular contraction is determined by two factors: the number of active muscle fibers and the frequency of neural stimulation of the muscle fibers.
Therefore greatest tension generates in skeletal muscle when it is stretched to the intermediate length.

how is carbon transferred from the biosphere to the hydrosphere?
Answer:
Animal and plant respiration place carbon into the atmosphere. When you exhale, you are placing carbon dioxide into the atmosphere. Plants use carbon dioxide from the atmosphere to make the building blocks of food during photosynthesis. Carbon is found in the hydrosphere dissolved in ocean water and lakes.

i dont know why wont you ask your dad
True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
no mutation random mating no gene flow infinite population size and no selection (natural nor forced).You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

An airtight, temperature-controlled glass box containing actively growing tomato plants was placed under a light source. Plastic wrapping that only transmits green light was placed over the box, and two days later air samples from inside the box were collected and analyzed. The most likely change in air quality is:
The most likely change in air quality is a decrease in carbon dioxide (CO2) present in the box.
Photosynthesis is the process by which green plants produce their own food in the presence of light and carbon dioxide. The most important indicator of air quality is carbon dioxide. This gas is removed during photosynthesis.
This implies that after two days, analysis of the air samples from the pot will definitely indicate a large decrease in the amount of carbon dioxide present in the box.

I think its B? Can someone explain it to me tho
Explanation:
I think it should be C because increase in temperature increases molecular motion. Therefore the speed of the moving molecules of both enzymes as well as the substrate will be accelerated. This
will enhance the colliding probability for both enzyme active sites and substrate molecules and more collisions occur between the enzyme active sites and substrate molecules generate greater chances for the reaction to occur. This can continue up to a certain point, after which there is a rapid decline in enzyme activity. This point is referred to
as optimum temperature. When the temperature increases beyond the optimum temperature, the hydrogen bonds, ionic bonds and other weak chemical bonds of enzyme active sites may be disrupted.
This will result a change in the shape of the active site of enzyme which will alter the complementary nature of the active site of enzyme molecules. Therefore, the
complementary binding of enzyme active sites and substrate molecules will be prevented. The above event is called as denaturation of enzyme molecules.
Therefore the rate of enzyme catalyzed reaction or in this case, photosynthesis will start to decline when the temperature increases beyond the optimum temperature and stops completely at certain
temperature, although rate of collision will keep on increasing.
What are two types of evidence that support the hypothesis that earth and the rest of the solar system was formed by a condensing nebula
Comets, Asteroids and metoeorites support the hypothesis that earth and the rest of the solar system was formed by a condensing nebula.
What are the functions of asteroids?An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere.
They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types ("stony") are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron).
Almost all of the asteroids in our solar system are orbiting in a broad band 19,400,000 miles wide between Jupiter and Mars. The asteroids are orbiting the Sun, each one traveling around the Sun fast enough for the orbits not to degrade.

What are the four most common elements in all living things
Answer:
Oxygen
Oxygen is the most abundant element contained within living organisms, composing about 65% of the human body. Oxygen is also the most abundant element in the Earth's crust, and in the air that is essential for most life on Earth. Oxygen's presence in the body is largely in the form of water, which is used to produce the energy within the body needed to sustain life.
Carbon
Carbon forms the basis for all life on Earth; indeed, life forms on Earth are referred to as carbon-based life forms, emphasizing the importance of this element for life. Carbon atoms readily bond to other atomic elements, such as oxygen and nitrogen. Since carbon can so readily bond to other elements, long chains of bonds can form and provide the physical and chemical structure needed for the complex processes and structures that occur within living organisms, such as structural proteins and genetic information in the form of nucleic acids.
Hydrogen
Hydrogen is the simplest element, as its atom contains only a single proton and a single neutron. As a result of this simplicity, hydrogen readily bonds with other elements, making it an important component for the formation of living organisms. Hydrogen is the other element (along with oxygen) which forms water, a crucial component for most life forms on Earth. Hydrogen is also a byproduct in many biological reactions, including photosynthesis and metabolism.
Nitrogen
Nitrogen is one of the most abundant elements on Earth, composing approximately 80% of the air on Earth. Nitrogen is an important element in the development of plant life, as compounds containing these elements are readily absorbed and used by plants. Nitrogen is also an important component of many proteins and deoxyribonucleic acids (DNA), which is crucial for genetic material to be passed on to subsequent generations of life.
Sulfur
Sulfur is a major component of two essential amino acids used by living organisms: cysteine and methionine. These amino acids, like all amino acids, are crucial for the construction of proteins that are used for structural stability and repair of living organisms. For example, the structural integrity of hair and feathers can be attributed to these amino acids. Sulfur is also used as a source of energy and is metabolized by some species of bacteria and other lower life forms.
Phosphorus
Phosphorus is used in the formation of phospholipids, a type of molecule that is a major component of the cell membrane of all living cells. Without this cell membrane, cells would not be able to develop and would not have the structural stability to form in the first place. This protective layer of phospholipids holds all the internal components of cells in place, allowing for the processes that maintain the life of the cell to take place. The phospholipid layer also protects the cell by keeping any unwanted or potentially destructive materials outside of the cell.

A. Reinforcement and support C. Elasticity
B. Exchange of gases D. Formation or root hairs
Reinforcement and support
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).
