Answer: The correct answer is thymine.
Explanation:
DNA is a complex chemical compound which carries genetic information of a living being. It is a double helix structure. The full form for this is deodorize nucleic acid.
This compound is made up of 4 nitrogenous bases named as adenine (A), guanine (G), cytosine (C) and Thymine (T).
Adenine forms double hydrogen bonds with Thymine and cytosine forms triple hydrogen bonds with guanine.
In RNA, the nitrogenous bases found are adenine (A), guanine (G), cytosine (C) and Uracil (U).
The nitrogenous base Thymine is the only base which is found only in DNA.
Hence, the correct answer is thymine.
Answer:
Thymine.
Explanation:
DNA is present as the genetic material in case of almost all the organisms except some viruses only. RNA is present as the genetic material in case of the few viruses only.
DNA is made of the four nitrogenous bases, pentose deoxyribose sugar and the phosphate group. The adenine, guanine and cytosine are present in both the RNA and DNA. Thymine is present in case of the DNA only and absent in RNA and other molecule.
Thus, the correct answer is option (4).
b. Uncooked rice
c. Cut watermelon.
d. Cooked beef.
Answer:
Adipose tissue
Explanation:
Cartilage is the connective tissue consisting of large round densely packed cells with the nucleus pushed to the side. Other forms of connective tissue include Dense regular and irregular connective tissues, fibrous connective tissues, and loose or areolar connective tissue.
The connective tissue consisting of large round densely packed cells with the nucleus pushed to the side is called cartilage. Cartilage is a type of connective tissue that has a large amount of ground substance matrix and cells called chondrocytes, along with some amount of fibers. Other forms of connective tissue include Dense regular and irregular connective tissues, fibrous connective tissues, loose or areolar connective tissue. Dense connective tissue, including regular and irregular, consists of collagenous fibers packed in different alignments. Fibrous connective tissues contain copious amounts of collagen fibers but few cells or matrix material. Finally, loose or areolar connective tissue is encapsulated in a matrix and is found around blood vessels and most body organs.

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.
