Answer: Monocytes.
Explanation:
Monocytes have a abundant amount of gray cytoplasm with fine lilac granules in it and because of this the cytoplasm appears ground glass.
The vacuoles are vacant and there is a gap sen in the cell as vacuoles when observed under microscope. The vacuoles of the monocytes are not stained.
They have a U-shaped nucleus and are extremely motile. The monocytes are lightly stained as compared to leukocytes.
The endoplasmic reticulum aids in the production and movement of proteins and other materials through the cell.
Answer:
D- Multicellular life
Explanation:
Multicellular organisms are those organisms composed of two or more cells, these species include most fungi, animals and plants. On the other hand, unicellular organisms include bacteria and archaea (i.e., prokaryotes), as well as unicellular eukaryotic species (e.g., protists). Multicellular organisms exhibit a higher organizational level compared to unicellular organisms because in these organisms cells are organized into successive hierarchical levels in order to carry out diverse functions (i.e., tissues, organs, organ systems, etc).
Answer:
Organisms get larger and develop into different stages of life >> Growth and development
Heal wounds, replace damaged cells >> Replace cells
Organisms make more of the species to keep them from going extinct >> Reproduction
Explanation:
Growth refers to the irreversible process by which organisms/tissues/cells increase in size and mass. Moreover, development can be defined as the progression from earlier to later maturation stages (e.g. fertilized ovule develops into a seed that will produce a mature tree). Cell replacement is a natural mechanism that occurs when cells become aged or in response to external/internal damage. During cell replacement, cells are produced from other cells by cell division. Finally, reproduction is a key biological process by which organisms (called parents) produce new genetically related organisms (i.e., offspring). According to the mode of transmission of genetic information, reproduction can be divided into sexual reproduction (offspring are different from parents) and asexual reproduction (offspring are the same as parents).
Answer:
The proximal tubule of nephron in the kidney is composed of single layer of cuboidal cells that are covered with striated borders.
Explanation:
Proximal tubules or proximal convoluted tubule is an important part of vertebrate kidney which is located between bowman's capsule and loop of Henle.
Proximal tubules are divided into 2 parts- Proximal convoluted tubules and Proximal straight tubules.
Proximal convoluted tubules are located entirely to the renal cortex and the Proximal straight tubules descend into the outer medulla.
The major function of Proximal tubules are mainly absorption and secretion.
The proximal tubules helps to regulate the pH from the filtration and also causes sodium reabsorption that is driven by P type ATPase.70% re absorption of sodium takes place in the proximal tubules through active transport.
Moreover elimination of ammonia takes place through proximal tubules by breaking glutamine to alpha ketoglutarate.
