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.

Answer:
False.
Explanation:
35 POINTS !!!! Part A
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

PHET Energy Skate Park Simulation .Consider this equation: gravitational potential energy = mgh. Which of those variables is changing as the skater moves up and down the track?
Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
In the equation gravitational potential energy = mgh, the variable that is changing as the skater moves up and down the track is the variable h, which represents the height or vertical position of the skater.
As the skater moves up the track, the height increases, resulting in a higher value for h. Conversely, as the skater moves down the track, the height decreases, leading to a lower value for h.
The other variables in the equation, m (mass) and g (acceleration due to gravity), typically remain constant unless specified otherwise. Therefore, the changing variable in this equation as the skater moves up and down the track is the height (h).

Which stage of mitosis occurs the least often and why?
Explanation:
The Anaphase stage is the shortest phase of mitosis. During this phase, disjunction occurs, and migration of sister chromatids away from each other to the poles of the cell occurs, leading to the formation of daughter chromosomes. Molecular motors use ATP to shorten the spindle fibers attached to each sister chromatid

Which statement is true regarding the taxonomic system?
Charles Darwin was the primary creator of the current taxonomic system.
All of the past, extinct species have been cataloged.
The current taxonomic system is based on the Linnaean classification system.
All of the current, living species in the world have been cataloged.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quich check
The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features. The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

how do organisms with many cell types develop from a single cell
Cell division, torso axis formation, tissue and organ development are all part of development, and cell differentiation refers to acquiring a final cell type identity.
What is cell division?The process by which a parent cell divides into two daughter cells is known as cell division.
Cell division is usually part of a larger cell cycle during which the cell grows and replicates its chromosomes before dividing.
Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Multicellular organisms form in a variety of ways, including cell division and the aggregation of many single cells. Colonial organisms form when many identical individuals band together to form a colony.
Thus, this way, organisms with many cell types develop from a single cell.

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.

Explanation:
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)
