Answer:

In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.

laiz [17]

Peter and rosemary discovered a natural ecosystem with an extreme climate, oscillating between cycles of intense drought and abundant rainfall, as well as an uncontaminated area that had never been explored by humans. This was an excellent location to study the evolution of Galapagos finches.

  • For their outstanding long-term studies showing evolution in action in Galápagos finches, Peter and Rosemary Grant are renowned.
  • They have shown that natural selection is responsible for the incredibly quick changes in body and beak size in response to variations in the availability of food.
  • Due to the lack of predators or rivals for the finches, Daphne Major makes an excellent location for research.
  • (The cactus finch is the only other finch on the island.)
  • The weather, and consequently the availability of food, has a significant impact on the medium ground finch's capacity to survive.

dimaraw [331]

A scientific claim is developed by answering questions raised through suitable hypotheses that allow making predictions, which can be tested by experimental procedures.

<h3>What is a scientific claim?</h3>

A scientific claim is a body of knowledge obtained by answering the equation formulated through the observation of the real world.

These observations are capable of raising plausible explanations or hypotheses that can be tested (confirmed or rejected) by using the scientific method.

An inquiry activity may be, for example, the observation of the movement of a cylinder in aqueous solution.

In conclusion, a scientific claim is developed by answering questions raised through suitable hypotheses that allow making predictions, which can be tested by experimental procedures.

Explain the connection between the oxidation of water in photosystem II of the light-dependent reactions and the synthesis of gl
dezoksy [38]

Answer:

Please find the explanation below

Explanation:

This question is describing the processes involved in photosynthesis. In the light-dependent stage of photosynthesis, specifically photosystem II (PSII), water is oxidized in a process called PHOTOLYSIS OF WATER. This process produces electrons and Hydrogen ions (H+). The electrons produced via this process is accepted by NAD+ to yield NADH.

The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).

The law of conservation of mass

Explanation:

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
