Within the inner membrane of a chloroplast, interconnected sacs of membrane called ________ are suspended in a thick fluid calle
antiseptic1488 [7]

Answer:

Thylakoids, stroma

Explanation:

The interconnected flattened sacs within the inner membrane of the chloroplast are called thylakoid. Many thylakoids are come together and get arranges in a stack called a granum.

Thylakoid contains chlorophyll pigment and is responsible for absorbing the sunlight and conducting light reaction. These thylakoids or grana are suspended in a liquid called the stroma.

The stroma contains the enzymes which are required in the light-dependent reaction. It contains DNA, ribosome, starch. The synthesis of organic molecules occurs in the stroma.

aleksklad [387]

Full Question (figure attached):

Nucleic acid segments and ar

DNA and RNA are nucleic acids that can store biological information based on the sequence of their nucleotide monomers. Figure 1 shows a short segment of each of the two types of nucleic acids. Which of the following best describes a structural difference between DNA and RNA?

A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.

C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand

D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups

Answer:

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.

Explanation:

A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases - this is false. Both contain four types of nitrogenous bases. DNA contains cytosine, guanine, adenosine and thymine, whereas RNA contains cytosine, guanine, adenine, and uracil.

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose. - this is true, each nucleotide in DNA contains a deoxyribose sugar, whereas each nucleotide in RNA contains a ribose sugar

C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand - this is false. DNA is composed of 2 strands, and RNA is composed of one, but the DNA strands run in an anti-parallel configuration (one runs 5'-3', the other runs 3'-5')

D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups - this is false, both DNA and RNA nucleotides contain phosphate groups
