In order for high force crossbridges to form in contracting skeletal muscle, calcium must a. bind to calmodulin to phosphorylate the myosin. b. phosphorylate the tropomyosin which moves it. c. phosphorylate the troponin to move the tropomyosin. d. bind to tropomyosin which moves the troponin. e. bind to troponin which moves the tropomyosin.
Answers
Answer:
e. bind to troponin which moves the tropomyosin.
Explanation:
Troponin (Tn) is a protein complex composed of three different proteins: troponin C (TnC), troponin I (TnI), and troponin T (TnT). This complex is found both in skeletal muscles and cardiac muscles, where TnC attaches calcium ions through four and three calcium ion-binding sites, respectively. When a muscle is relaxed, Tn attaches to tropomyosin to prevent muscle contraction. During muscle contraction, calcium channels open and cytosolic calcium ions bind to TnC, thereby Tn changes its conformation and moves the tropomyosin. This process relieves the inhibition of the interaction between actin and myosin filaments, which makes muscle contraction possible.

How is viral reproduction different from the reproduction of single-celled and multicellular
organisms?
A. The virus depends entirely on a host cell to reproduce.
B. The virus relies on nucleic acids, such as DNA, to reproduce.
C. The virus relies on proteins to reproduce.
D. The virus reproduces very rapidly, but in smaller numbers.
Answers
Answer:
A. The virus depends entirely on a host cell to reproduce
Viral reproduction different from the reproduction of single-celled and multicellular organisms because the virus depends entirely on a host cell to reproduce. Thus, option A is correct.
What are the difference between single- celled and multicellular organism?The main difference between single- celled and multicellular organism is that single- cellled organisms are made up only single cell on the other hand multicellular organisms are made up of multiple cells.
Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Prokaryotic Cell
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.
Eukaryotic cell
Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organism.
Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,viral reproduction different from the reproduction of single-celled and multicellular organisms because the virus depends entirely on a host cell to reproduce. Thus, option A is correct.

Which is a correct graphical representation of the organization levels of a
biological system?
Answers
Answer:
1. Biosphere
2. Ecosystem
3. Community
4. Population
Explanation:
The correct graphical representation of the organization levels of a biological system is as follows:
Cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere. What is the level of organization of the biological system?The level of the biological system may be defined as the arrangement of structures that are usually characterized by relationships with things at higher levels that are being composed of things at the next lower level. A cell is the smallest level of organization for living things while the biosphere is the highest level of organization for living things.
A cell is the basic structural and functional unit of living organisms. The collection of cells gives rise to the formation of tissues which are combindly known as organs. Organs give rise to the organ system that completely formed a living entity.
Therefore, the correct graphical representation of the organization levels of a biological system is well represented above.

B. tRNA is always present in a cell, but Never present in viruses
C. Ribosomes are always present in a cell, but Never present in viruses.
D. Genes are always present in a cell, but always present in viruses..
Explanation:
A. RNA polymerase is always present in a cell, but sometimes present in viruses. RNA polymerase is the enzyme responsible for transcription in eukaryotic cells, it is the enzyme that stimulates transcription, that is, the passage from DNA to RNA. All RNA viruses encode in their genome an RNA-dependent RNA-polymerase (RdRp) that acts as a catalytic subunit, along with other viral and cellular proteins, in the replication of the viral genome. B. tRNA is always present in a cell, but Never present in viruses Transfer RNA is a type of ribonucleic acid that is responsible for transporting amino acids to ribosomes where, according to the sequence specified in a messenger RNA (transcribed, in turn , from DNA), proteins are synthesized. C. Ribosomes are always present in a cell, but Never present in viruses. Ribosomes are responsible for the granular appearance of the cytoplasm of cells. It is the most abundant organelle, several million per cell. Viruses do not have cytoplasm or ribosomes (elements necessary to form a cell), so they cannot multiply on their own and they need to infect the cell of another organism to do so.D. Genes are always present in a cell, but always present in viruses.Genes are the storage units of genetic information, they are fragments / segments of DNA that encode a specific functional product. Viruses are small pieces of RNA (ribonucleic acid) or DNA (deoxyribonucleic acid), many are encapsulated in an envelope made of base of proteins known as capsid, others protect their genetic material with a membrane or envelope derived from the cell they infect and some others also surround their capsid with a cell membrane. RNA viruses bring with them their own genetic information copying machines (eg, RNA polymerase enzyme) or possess genes (genetic information) that produce the proteins required to assemble the copying machines within the cell that they infect, thereby which makes them independent of the cellular machinery and capable of infecting cells that are not actively reproducing.

ATP synthesis takes place in the mitochondria of eukaryotic cells.
ATP is regenerated from ADP through the process of phosphorylation.
energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups.
most of the readily available energy stored in ATP is stored during the manufacture of adenosine.
the ribose sugar in the model above is the direct product of photosynthesis.
Answer:
The correct answer is given below:
Explanation:
ATP synthesis takes place in the mitochondria cell organelle in the eukaryotic cells, however, a small part of ATP generation takes place in other cell regions but most of the ATP synthesis is occurs in the inner membrane of mitochondria which makes it energy house of the cell.
ATP is formed by the addition of phosphorus to ADP and this process is called phosphorylation.
Each bond of the adenosine and its three phosphates has stored energy in their covalent bonds. The last two phosphates have a high amount of energy in their bond.

mendel,s experiment is applicable not only in plant but also in animals
Answers
Answer:
Yes, this is true. This is because animals also carry genes which codes for a certain trait, and these traits have their own allele. Mendel's experiment portrayed tall plants and dwarf plants being crossed, moreover the colour of the flowers could also be taken as an example. In the similar way, animals, for example, mice, could be white furred or brown furred. They both carry alleles which codes for their fur colour, like plant alleles which codes for either tall or dwarf.
