Write a 2 paragraph summary about the structure of DNA from the information on the first page.
FYI the picture is attached

Answers

Answer:

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT might instruct for blue eyes, while ATCGCT might instruct for brown. The complete DNA instruction book, or genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes.

COMPARE AND CONTRAST ACTIVE IMMUNITY AND PASSIVE IMMUNITY

Answers

Active Immunity is natural.

Passive Immunity is maternal.

Active Immunity from Vaccination.

Passive Immunity is Artificial.

Passive Immunity:

   Does not require previous exposure to a disease agent

   Takes effect immediately

   Does not last long (up to a few months)

Active Immunity is produced inside of the body, whereas passive immunity is introduced from outside of the body.

Active Immunity is from direct infection and vaccination.

Passive Immunity is from Breast milk, Injection, Mother to baby through the placenta.

Active Immunity takes effect over time (typically several weeks).

Passive Immunity takes effect immediately.

Active Immunity's length of efficacy is Long-term to lifelong.

Passive Immunity is short-term.

Active Immunity is produced by memory cells, Passive Immunity is not.

Hope this was insightful and enough information.

Answer: While active immunity occurs when an individual produces antibodies to a disease through his or her own immune system, passive immunity is provided when a person is given antibodies

Explanation: wo types of immunity exist — active and passive: Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else.

Which statement describes a connection between photosynthesis and cellular respiration?

Question 6 options:

Water is a product of photosynthesis and is a reactant for cellular respiration


Oxygen is a product of both photosynthesis and cellular respiration


Oxygen is a product of photosynthesis and is a reactant for cellular respiration


Water is a product of both photosynthesis and cellular respiration

Answers

Answer: Water is a product of both photosynthesis and cellular respiration

Explanation:

The correct answer is C. Oxygen is a product of photosynthesis and is a reactant for cellular respiration.

What is photosynthesis and cellular respiration?

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells and involves the absorption of light energy, the conversion of this energy into chemical energy, and the synthesis of glucose from carbon dioxide and water. Oxygen is a byproduct of photosynthesis, as it is produced when water is split into hydrogen and oxygen during the process.

Cellular respiration is the process by which cells convert the chemical energy stored in glucose into ATP (adenosine triphosphate), which is the main source of energy for cells. This process occurs in the mitochondria of cells and involves the breakdown of glucose through a series of reactions that release energy. Oxygen is a reactant for cellular respiration, as it is required for the breakdown of glucose.
