Answer:
the cell wall!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Explanation:
it coversssssssssssssssssssss the cell and protects it
Answer:
Since the beginning of life of the first multicellular organisms, the preservation of a physiologic milieu for every cell in the organism has been a critical requirement. A particular range of osmolality of the body fluids is essential for the maintenance of cell volume. In humans the stability of electrolyte concentrations and their resulting osmolality in the body fluids is the consequence of complex interactions between cell membrane functions, hormonal control, thirst, and controlled kidney excretion of fluid and solutes. Knowledge of these mechanisms, of the biochemical principles of osmolality, and of the relevant situations occurring in disease is of importance to every physician. This comprehensive review summarizes the major facts on osmolality, its relation to electrolytes and other solutes, and its relevance in physiology and in disease states with a focus on dialysis-related considerations.
Answer:
Cardiac muscle.
Explanation:
Cardiac muscle is also known as heart muscle. These muscles regulate the proper working and functioning of the heart.
Cardiac muscles are involuntary muscles and show striations under the microscope. These muscles are uninucleate and connected by the intercalated disc. Cardiac muscles are branched so that each cardiac cells may attach with atleast with or four other cardiac cells.
Thus, the correct answer is option (A).
Answer:
The correct answer is b) asexually reproducing organisms, but not sexually reproducing organisms, pass all mutations to their offspring.
Explanation:
In asexually reproducing organisms all the mutation is passed to the offspring so the offspring are identical to the parents. Daughter cells contain all the genes that are present in the parent, therefore, in asexually reproducing organisms mutation leads to more evolutionary change.
In sexual reproduction, the offspring get half genes from male parents and half from female parent so a parent does not pass all the mutation in the offspring and in sexual reproduction selection pressure eliminate those offspring that have bad mutation so that the wrong mutation can not pass to next generation.
Therefore the correct answer is b.
Answer:
C. Pores
Explanation:
Nuclear pores, small channels that span the nuclear envelope, let substances enter and exit the nucleus. Each pore is lined by a set of proteins, called the nuclear pore complex, that control what molecules can go in or out.
