DNA and amino acids hope this helps
B. nucleolus.
C. chromatin.
D. DNA.
Answer:
Option A, Cytoplasm
Explanation:
Cytoplasm is the fluid contained with in the cell membrane into which all cell organelles are found including the nucleus. Cytoplasm basically has two parts a) endoplasm and b) ectoplasm. The endoplasm has all the organelles while the ectoplasm is the fluid at the periphery of cell membrane. The cell memebrane keep the cytoplasm confined with in the cell and does not allow it to spill.
Since all the cell components are found with in the cytoplasm, it is clear that cytoplasm lies out of the nucleus. Thus, option A is correct.
Answer:
The correct answer will be option- A
Explanation:
The nucleus is the membrane organelle which encloses the DNA of the organisms. The presence of the nucleus is the characteristic feature of the eukaryotes.
The nucleus encloses the genetic material in the form of either DNA or a loosely arranged structure called chromatin. The nucleus also contains a structure called nucleolus distinguished by a dense round structure during the interphase.
Since the nucleus lacks the cytoplasm which is enclosed by the cell membrane of the cell therefore, option-A is the correct answer.
b. by polluting near by streams with pesticides and herbicides
c. by recycling
Answer:
The correct answer is the b-by polluting near by streams with pesticides and herbicides option
Explanation:
Hello!
let's solve this!
Agriculture is helping to reduce biodiversity since with the use of herbicides and pesticides, living things can no longer feed. Also when placed near streams, they also contribute to pollute the waters.
The correct answer is the b-by polluting near by streams with pesticides and herbicides option
b. two or more plastics mixed together to make a new plastic
c. two or more materials mixed together that chemically mix into a new material
d. two or more materials mixed together to make a stronger material but the individual components remain visible
GREETINGS!
D is the answer
Explanation:
A composite is made by combining two or more other materials so they improve one another but keep distinct and separate identities in the final product. So a composite isn't a compound (where atoms or molecules bind together chemically to make something quite different), a mixture (where one material is blended into another), or a solution.

Answer:
Alveoli
Explanation:
Answer:
brush border cells....!!
The simple cuboidal cells of the proximal tubule are referred to as Proximal Convoluted Tubule (PCT) cells.
They have a distinct feature of having prominent microvilli on their luminal surface that forms a brush border.
These microvilli contribute to creating a large surface area which facilitates the maximization of the absorption and secretion of solutes including Na+, Cl¯, glucose, among others - a key function of this portion of the nephron.
These cells are responsible for the active transport of ions across their membranes and hence they possess a high concentration of mitochondria to produce sufficient ATP.
The PCT cells, forming a simple cuboidal epithelium, are active in secretion and absorption of molecules.
They are observed in the lining of the kidney tubules and are critical to the kidney's filtration function.
