Answer:
D. The energy flow is not dependent on any members of the ecosystem
Explanation:
The energy flow in an ecosystem is not dependent on any member of the ecosystem. It is the flow of energy through the food chain, energy is passed from members in one trophic level to members in another or the next trophic level. The flow of energy in an ecosystem is important because it helps in maintaining balance in ecology.
what are the limitations of the respiratory system?
Answer:
Having gills, or the ability of gills.
Explanation:
Our lungs can't filter out water and use the oxygen in the water, sadly.
And, we can't hold our breath for that long, compared to other mammals (the only way that we can hold our breath for a long time is if we breathe in pure oxygen).
If a blue-colored flower crossed with a white-colored flower produced light blue-colored flower offspring, then it's most likely a case of
independent assortment.

How do nutrients move through an environment? What drives the movement of nutrients?
Answer:
The nutrient cycle is a system where energy and matter are transferred between living organisms and nonliving parts of the environment. This occurs as animals and plants consume nutrients found in the soil, and these nutrients are then released back into the environment via death and decomposition.
The nutrient cycle is a system that transfers energy and matter between living organisms and non-living elements of the environment.
How do nutrients move?As the concentration of nutrients around the root system decreases, nutrients from higher concentration areas diffuse - or move - toward low concentration areas and the roots. They only move a short distance, however. Potassium (K) and phosphorus (P) primarily move via diffusion.The nutrient cycle is a system that transfers energy and matter between living organisms and non-living elements of the environment. This occurs when animals and plants consume soil nutrients, which are then released back into the environment through death and decomposition.The movement of nutrients to the root surface in response to a concentration gradient is referred to as diffusion. When nutrients are found in higher concentrations in one area than in another, there is a net movement to the low-concentration area, resulting in equilibrium.To learn more about : Diffusion.

Which part of an animal cell controls the cell's activities
Answer:
Nucleus
Explanation:
Cell structures and their functions
Cytoplasm A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen.
Nucleus Contains genetic material, including DNA, which controls the cell's activities.
You just went to McDonald's and purchased a Big Mac what type of macromolecule is represented in each of the following?
Answer:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.
in what ways is ATP like a fully charged battery?
Answer:
ATP ATP can be compared to a fully charged battery because both contain stored energy, whereas ADP resembles a partially charged battery. Releasing Energy From ATP The energy stored in ATP is released when ATP is converted into ADP and a phosphate group.
Explanation:
The ATP molecule is comparable to a battery that can be recharged. It is ATP when ultimately charged. It's ADP when it's worn out. When the battery runs out, it is simply recharged rather than discarded.
What is ATP?A vital "energy molecule" in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers cells' energy by liberating its phosphate groups when it interacts with enzymes like ATP triphosphatase. The molecule comprises an adenine bicyclic system, a furanose ring, and a triphosphate chain.
The discovery of ATP was announced in 1929 by two research teams. It was isolated from mammalian muscle and liver by Cyrus H. Fiske and Yellapragada Subbarow at Harvard Medical School (Boston). Karl Lohmann discovered it in muscle tissues while working for the Kaiser Wilhelm Institutes in Berlin and Heidelberg.
Over the next 15 years, ATP separation from other sources came next. In 1987, Koscak Maruyama of Chiba University (Japan) provided a thorough analysis of ATP's discovery and structural elucidation.
Therefore, ATP is like a rechargeable battery because it can be recharged and discharged.

Strong pull
Weak push
The force used on your arm when you walk a dog on a leash and it tries to
chase something is known as Strong pull.
Strong pull is defined a physical force which is usually aggressive or
coercive and it involves the movement in a particular direction due to
different factors or reasons.
The Dog in the example has a leash on and applies a force in the direction of
the thing it wants to chase which is a perfect example of a strong pull.

A characteristic common to eukaryotic cells that is not found in prokaryotic cells is the
cell membrane
presence of DNA
use of ribosomes for protein synthesis
presence of mitochondria
Answer:
Presence of the Mitochondrion!!
Explanation:
~
A characteristic common to eukaryotic cells that are not found in prokaryotic cells is the presence of mitochondria. Thus, the correct option for this question is D.
What is a Prokaryotic cell?A prokaryotic cell may be defined as a type of cell which is present in prokaryotes. This type of cell typically lacks a well-defined nucleus and other membrane-bound cell organelles. Organisms like bacteria, archaea, etc. possess this type of cell.
All prokaryotes and eukaryotes have a cell membrane known as a Plasma membrane. Most prokaryotic organisms have a small amount of genetic material in the form of a single molecule known as circular DNA.
Protein synthesis is one of the essential functions of all cell types. Ribosomes are significantly found in every type of eukaryotic as well as prokaryotic organisms like bacteria.
Therefore, the presence of mitochondria is a characteristic that is only common to eukaryotic cells but is not found in prokaryotic cells.
