What are the two autotrophic forms of metabolism​

Biology
1 answer:
cricket20 [7]2 years ago
3 0
Autotrophic behaviour depends on the ability of the cell to carry out photosynthetic or aerobic respiratory metabolism, which are the only processes able to deliver sufficient energy to maintain carbon fixation. The Calvin cycle is used by bacteria to synthesize organic compounds.

Mendel did experiments in which he kept track of the inheritance of seed texture (wrinkled or smooth). First he created true-bre
sveticcg [70]

Answer:

smooth was dominant over that for wrinkled

Explanation:

In complete dominance, a gene may have two different variants or 'alleles', dominant and recessive. A dominant allele is a gene variant that is able to produce a certain phenotype, even in the presence of other alleles, while a recessive allele is a gene variant that is masked by the dominant allele in heterozygous individuals (i.e., individuals that inherited different alleles from each parent). By crossing smooth and wrinkled pea plants, Mendel observed the offspring (F1) were smooth rather than mixed, indicating one type of seed texture was dominant over the other. Subsequently, Mendel observed that alleles for different traits (e.g., seed texture and seed color) assorted independently during meiosis.

Which discovery in the 1800s lead to the development of germ theory
bogdanovich [222]

<u>Answer:</u>

Discovery of vaccine for smallpox, viruses and actual organisms that cause many diseases lead to the development of Germ Theory.

<u>Explanation:</u>

  • Theory was the 'predominant theory' of 'disease transmission' before germ theory but it is no longer accepted as a 'scientific theory' of diseases.
  • 'Formal and reliable experiments' on germs and diseases relationship were 'conducted by Louis Pasteur'.
  • He showed that growth of microorganisms was not a spontaneous generation and his pasteurization experiment provided key pieces of evidence that supported germ theory.

Which of the following statements is true?
Jlenok [28]
<span>Let's look at all the statements:Which of the following statements is true? Parts of an ecosystem only include biotic factors such as plants and animals. - this is not true, it also includes abiotic factors, such as stones If a common plant in an ecosystem becomes diseased, the ecosystem may become unbalanced. - this is the true statement! it could be a source of food for other animals, and thus it could influence the population of other species Abiotic factors include decomposers such as fungi and bacteria. - this is false, those are biotic factors. Tundras have a high diversity of species. - this is not true - compared to the rain forest, for example, tundras are not very diverse</span>

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. Oxygen wil
Juli2301 [7.4K]

The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.

Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.
