The backbone of the double helix is made up of ____ molecules and ____ groups, and the two chains are joined together by hydrogen bonds between the ____

Answers

Answer:

The backbone of the double helix is made up of SUGAR molecules and PHOSPHATE groups, and the two chains are joined together by hydrogen bonds between the NUCLEOTIDE BASES

Explanation:

DNA is a double helix structure. It looks similar to a twisted ladder. The backbone is like the sides of the ladder. They are made up of sugar molecules called deoxyribose and phosphate linked together. The nucleotide bases make up the rungs. Each rung is made up of 2 complimentary bases that are held together by hydrogen bonds.

Final answer:

The backbone of the double helix is made of sugar-phosphate molecules and groups. The two chains are joined by hydrogen bonds between the nitrogenous bases. These bases are adenine (A), thymine (T), cytosine (C), and guanine (G)

Explanation:

The backbone of the double helix, such as DNA, is made up of sugar-phosphate molecules and sugar-phosphate groups, and the two chains are joined together by hydrogen bonds between the nitrogenous bases

More specifically, the sugar is deoxyribose, and the phosphate group is a component of each nucleotide. The strands of the helix run in opposite directions, making them antiparallel. The nitrogenous bases that join the two strands are adenine, thymine, cytosine, and guanine - adenine always binds with thymine and cytosine with guanine.

Explain the characteristics scientists use when observing organisms and placing them in the six kingdoms .

Answers

The characteristics that scientists used to classify living organisms into six kingdoms include the following:
1. Cell type: living organisms are classified into prokaryotes and eukaryotes based on the presence of nucleus and distinct arrangement of the organelles in their cells.

2. Mobility: living organisms are categorized into kingdoms based on their ability or inability to move about.

3. Cell structure: the cells structure was used to divide living organisms into plants and animals. Those living organisms that have cell wall are classified as plants while those who do not have cell wall are classified as animals.

4. Number of cells: living organisms that are made up of only one cell are classified as unicellular while those with many cells are termed multi cellular.

5. Reproduction method: living organisms are classified based on whether they reproduce sexually or asexually.

6. Manner of obtaining energy: living organisms that can prouduce their own food are called autotrophs while those that can not produce their own foood are termed heterotrophs. Plants are essentially categorised as autotrophs while animals are described as heterotrophs.

Answer:

cell type – prokaryotic or eukaryotic

cell structure – cell wall

nutrition – autotrophic or heterotrophic

body type – unicellular or multicellular

Brain evolved in the lineages before the evolution of
fishes.
A. True
B. False

Answers

Yes, brain is involved in the lineages before the evolution of fishes

A. True ✓

Final answer:

The statement is true. The evolution of the brain predates the evolution of fishes.

Explanation:

The statement that the brain evolved in the lineages before the evolution of fishes is true.

The evolution of the brain can be traced back to earlier lineages, such as invertebrates like worms and insects. These organisms had simple nervous systems that gradually evolved into more complex structures. As vertebrates evolved, the brain became more sophisticated, with different regions responsible for various functions.

Fishes, being vertebrates, have brains that are more advanced compared to invertebrates. However, they are not the first organisms to have evolved brains. The evolution of the brain predates the evolution of fishes.
