Cell- The fundamental units of all living organisms are cells. There are many billions of cells in a human body. They provide the body structure, absorb nutrients from meals, turn those into energy, and perform certain tasks.
Extracellular Matrix ECM- The extracellular matrix (ECM) is a complex network made up of several multidomain macromolecules arranged according to the cell/tissue in which they are found. The mechanical characteristics of tissues are influenced by the structural stability of the composite formed by the linking of ECM components.
Macromolecules- Any extremely big molecule, typically having a diameter between 100 and 10,000 angstroms ([tex]10^{-5}[/tex] to [tex]10^{-3}[/tex] mm). The smallest component of a material that nevertheless has its distinctive qualities is its molecule.

. If the producer level of an ecosystem contains 46,894 calories, how much energy wouldbe found at the secondary consumer level of that same ecosystem?a. 4,689 caloriesb. 468,940 caloriesC. 468 caloriesd. 46,894 calories
Answers
Energy levels in an ecosystem
To be able to calculate how much energy there is at a certain level in an ecosystem, it is necessary to understand how the energetic pyramid works: it shows the energy retained as new biomass at each trophic level.
from bottom to top:
-Solar energy
-primary producers: 100% of energy
-primary consumers: 10% of energy
-secondary consumers: 1% of energy
-tertiary consumers: 0.1% of energy
Therefore, if there is an ecosystem with 46,894 calories, to know how many calories would be at a secondary consumer level it is necessary to multiply that number by 0.01 (which corresponds to 1% of the total energy). Then:
46,894 x 0.01 = 468.94
Therefore, the correct answer to this question is option c, 468 calories.

Scientific researchers discovered agents that behaved like bacteria causing diseases such as rabies and hoof-and-mouth, but were much smaller. At this time it became the general view that viruses were biologically "alive." This changed in 1935 when the tobacco mosaic virus was crystallized and scientists demonstrated that the particles lacked any mechanisms necessary for metabolic function. It was determined that viruses consisted of a nucleic acid, DNA or RNA, surrounded by a protein shell and the scientific view changed: viruses are complex biochemical mechanisms but not alive. When not in contact with a host, the virus remains dormant. During this time there are no biological activities occurring and the virus is nothing more than a static organic particle. In this state viruses can remain for extended periods of time, waiting to come into contact with the appropriate host. When in contact with a host, it becomes active, reacts to its environment and/or host and directs its efforts toward self-replication. The viral goal now is to produce more viruses to attack host cells.

What is Dissolve?This is referred to as the process in which a solute is merged with a solvent thereby forming a solution and it varies according to certain properties and features.
The supplies such as beads, feathers, and crayons are all incapable of forming a solution with water as a result of their molecular structures and their non polar parts which is why they are referred to as being insoluble substances.

statement that describes the process of cellular respiration
Answers
Answer:
Statement that describes the Process of Cellular Respiration is Converting chemical energy that is stored in food molecules into a form that is useful to living things.
Explanation:
Living cells release energy through the breakdown of glucose molecules, a process known as cellular respiration. There are three processes that make up cellular respiration.
GlycolysisKrebs CycleElectron Transport ChainGlycolysis, the first phase of cellular respiration, happens in the cytoplasm. In this step, enzymes convert a glucose molecule into two pyruvate molecules, releasing energy that is then transferred to ATP. Following glycolysis, the pyruvate is transformed into two molecules of acetyl CoA in a brief event known as the transition reaction.
The other two phases of cellular respiration take place in the organelle known as a mitochondrion. The inner membrane of the mitochondrion encloses a region known as the matrix, and the outer and inner membranes are separated by an intermembrane space.
The Krebs cycle, the second phase of cellular respiration, occurs in the matrix of a mitochondrion. At this point, the cycle completes two rounds, producing all of the carbon atoms.

When the Carbon dioxide changes its state from gas to solid directly that is called dry ice.
How might dry ice be used for cleaning?Similar to sand blasting, dry ice cleaning, commonly referred to as cryogenic cleaning, uses solid CO2 or dry ice pellets instead of sand. The pellets expand by a factor of 700 when they hit the ground and evaporate into carbon dioxide gas. This expansion causes the contaminant to be raised and separated from the basic substance. creates daily dry ice blasting tools and exports them to numerous nations across the world.
In order to create dry ice, gaseous CO2 is first compressed and rapidly cooled to create liquid CO2. The liquid is next allowed to expand at a lower pressure to create CO2 snow. Finally, a hydraulic press compresses this snow into usable Dry Ice blocks, slices, or pellets.

False statements regarding a bacterium that is R+ is F+.
Everywhere you look, you can find bacterium (plural: bacterium), which are typically free-living organisms made up of just one biological cell. They make up a sizable group of prokaryotic bacteria. Bacteria, which are among the earliest life forms to exist on Earth and are typically a few micrometers in length, are found in most of its environments. The deep biosphere of the Earth's crust, acidic hot springs, radioactive waste, and soil all support bacterial life. By recycling nutrients, such as fixing nitrogen from the atmosphere, bacteria play an important role in many stages of the nutrition cycle. The decomposition of dead bodies is a part of the nutrition cycle, and the putrefaction stage is brought on by bacteria. Extremophile bacteria offer the nutrients required to maintain life in the biological communities surrounding hydrothermal vents and cold seeps.
