Mitochondria converts the chemical energy stored in food into compounds that are more convenient for the cell to use.
The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria.Almost all eukaryotic cells (cells with clearly defined nuclei) have a membrane-bound organelle called a mitochondrion, whose main job is to produce huge amounts of energy in the form of adenosine triphosphate. Mitochondria normally have a circular to oval shape and can be anywhere between 0.5 to 10 m in size. In addition to providing energy, mitochondria also generate heat, control cell growth and death, and store calcium for cell signaling functions.Variables influence how many mitochondria each cell contains.Therefore, the correct answer is mitochondria.

What are representative organisms from the archea and eukarya, fungi, and protista?
In 1969, R.H. Whittaker proposed a classification of five kingdoms. His classifications of the kingdoms were Monera, Protista, Fungi, Plantae, and Animalia. He primarily uses cell structure, body organization, mode of nourishment, reproduction, and phylogenetic linkages as classification criteria.
Representative organisms of Archea: Pyrolobus fumarii, which has a maximum survival temperature of 113 °C (235 °F), and species of Picrophilus, which were isolated from acidic soils in Japan and are the most acid-tolerant creatures known—capable of growth at about pH 0—are all members of the archaea.
Representative organisms of Eukarya: Prokaryotes are single-celled microorganisms that lack nuclei, such as bacteria and archaea, while Eukaryotes, which include ourselves and all other animals, plants, fungi, and single-celled protists, have nuclei that serve to separate their DNA from the rest of the cell.
Representative organisms of fungi: Yeasts, rusts, smuts, mildews, molds, and mushrooms are all examples of fungi. Additionally, there are several fungus-like species that do not actually belong to the kingdom Fungi but are frequently referred to as fungi, such as slime molds and oomycetes (water molds).
Representative organisms of protista: The protists are a varied group of eukaryotes that are indistinguishable from fungi, animals, or plants. Amoebae, red algae, dinoflagellates, diatoms, euglena, and slime molds are among the creatures that belong to the kingdom of Protista.

Scientists sometimes build conceptual models rather than physical models because in some cases it is easier to experiment on a conceptual model than a physical model. true false
It is true that scientists sometimes build conceptual models rather than physical models because in some cases it is easier to experiment on a conceptual model than a physical model.
Conceptual models are ethereal, psychological depictions of proper task execution. In order to systematize processes, people employ conceptual models instinctively and intuitively.
Reasons why the answer is true:
First off, it's because it might occasionally be challenging or impossible to create a physical model of a naturally occurring occurrence. Second, since testing ideas on a conceptual model is sometimes simpler than testing them on a physical one. Thirdly, because in some circumstances conceptual model development is required before physical model construction.

Why do signaling responses that involve changes in proteins already present in the cell?
Protein signalling reactions take milliseconds since they are already present in the cell, but gene expression reactions take hours. This occurs because both the protein and the modifying enzyme needed to change the protein are already present in the cell.
What role do proteins play in cellular signalling?The proteins known as receptors in cells attach to signalling molecules to start a physiological reaction. Different chemicals are unique to certain receptors. Nerve growth factor receptors bind nerve growth factor, insulin receptors bind insulin, dopamine receptors bind dopamine, and so on.
The intracellular receptor is the same in many different types of cells, but the collection of genes that the receptor controls varies depending on the cell type.

Richard feels that the increasing use of fuels such a coal or diesel to generate electricity are leading to pollution in his neighborhood. He therefore decides to use solar energy as a source for generating electricity. Which device should Richard use?
The potential for solar energy is the highest of all the available renewable energy sources. The two main solar energy technologies are concentrated solar-thermal power (CSP) and photovoltaics (PV) (CSP).
Unlike fossil fuels, which will eventually run out, the sun has more than enough energy to supply the demands of the entire planet. The sole constraint on solar energy as a renewable resource is our capacity to efficiently and economically convert it to electricity. Some energy sources, as opposed to fossil fuels, are entirely renewable and don't release greenhouse gases. Solar energy, hydropower, wind, geothermal, and biomass energy are some of these green and sustainable alternative energy sources. The energy sources that are now available are quickly running out due to the rising demand for energy. Large-scale fuel use results in the release of many gases and undesirable airborne particulates.

Explanation:
What path does a protein in the secretory pathway take, starting from its site of synthesis?.
Every protein starts its production in the cytoplasm. However, some are moved to other cellular locations while the majority remain there permanently. Post-translational transport may be used to import them into the mitochondrion, peroxisome, chloroplast, and nucleus.
Beginning with the intake of amino acids, which are utilized by the rough endoplasmic reticulum to create freshly produced proteins, the secretory route proceeds in a vectorial fashion. The Golgi complex receives these new proteins and processes and sorts them there. Protein cargo is transported from the ER to the Golgi, where it is altered before being transferred to various locations inside the cell, such as the lysosomes and the cell surface. Proteins produced by the endoplasmic reticulum (ER) are processed in the Golgi before being sent to the cell.learn more about protein here: https://brainly.com/question/10058019

How would you isolate the serum, and not the plasma, from the blood if you just withdrew a fresh vial of blood from the sheep without adding any anticoagulant?
To isolate the the serum, and not the plasma, from the blood if you just withdrew a fresh vial of blood from the sheep without adding any anticoagulant, you should let the blood sit for 10 minutes, then withdraw the top layer (serum). Hence, option b is correct.
Without using a centrifuge, whole blood can be separated from plasma or serum by simply letting it stand or just sit for about 10 minutes . All of the cells will eventually settle down due to gravity (if time is not the question). The supernatant is the plasma if citrated blood is allowed to stand in a tube.
The serum will eventually separate, though, if you leave the undiluted whole blood to stand. This might not be as useful if you are working with small amounts of blood, but you could still try it.

What is a chemical reaction called that builds new and larger molecules from camller starting molecules?
A chemical reaction called that builds new and larger molecules from smaller starting molecules is called anabolism.
In the field of science, anabolism can be described as a process through which larger, complex molecules are made from simpler, smaller molecules. In the body of an organism, the process of anabolism results in the formation of complex biomolecules required for sustaining life.
As opposed to catabolism, the process of anabolism requires energy. In the body, energy in the form of ATP is usually used for the reactions of anabolism to occur.
A simple example of anabolism is the production of proteins from amino acids. Amino acids join together to make long chains in order for the formation of proteins.
