Fossils of a microscopic organism are found in rocks determined to be over 3.5 billion years old. Identify TWO types of evidence

that would help answer the question of whether the organism was photosynthetic.
Biology
1 answer:
scZoUnD [109]3 years ago
3 0

Answer:

The first organisms that did photosynthesis used hydrogen to carry it out as plants do today, although at that time hydrogen sulfide gas was abundant, that is why it was supposed that they used that hydrogenated source as a requirement for photosynthesis In this way, the presence of gaseous and sulfur structures in these fossils could affirm that they were photosynthetic.

On the other hand, it is believed that the first photosynthetic organisms were not plants per se, but rather prokaryotic organisms. Photosynthetic life begins in water without a doubt and around 400 million years ago, plants conquered the air, at which time they developed a material known as a cuticle and which acts as a waterproof to prevent desiccation, but which in turn prevents gas exchange, which led to the next evolutionary step: the appearance of stomata.

Explanation:

According to Carrión, who was a «later, during the Carboniferous, the first trees and the first forests appear. Only the flower delays its appearance until 140 million years ago (Lower Cretaceous) although it arrives giving rise to plants (angiosperms) that will later have greater evolutionary success, since although the flowers lack greater adaptive advantages, they do allow more development fast from the seeds, which in the face of a catastrophe like the fall of a meteorite is an advantage, since it allows them to recover quickly ”.

Thus, "the great invention of angiosperms is the appearance of very rapid fertilization and the rapid formation of a seed, through a process of evolutionary alteration of embryonic development that is known as progenesis and leads to the passing of a individual with a late sexual development to another in which sexual maturation occurs much faster ”, Carrión details.

In short, a process of acceleration of embryonic development as a simple consequence of a mutation in a regulatory gene, and an organism competitively much higher from the ecological point of view emerges, capable of replacing a gymnosperm from its ecological niche. Not surprisingly, in the words of the UMU Professor, "the places where plants grow best today are places like the tropics, with lots of light and lots of water and where angiosperms predominate."...

Kisachek [45]

Answer:

2. synthesize its own food

Explanation:

Based on how they obtain their nutrition, living organisms has been classified to be either producers, consumers, or decomposers. Producers are organisms capable of synthesizing their own food using light (photosynthesis) or inorganic chemicals (chemosynthesis).

Consumers, on the other hand, cannot synthesize their own food and hence, rely on other organisms to obtain their energy source. Consumers feed on other organisms to obtain energy. In this question, a fruit fly is classified as a CONSUMER because it cannot synthesize its own food.

liberstina [14]

Deforestation is the most serious problem facing the world’s forests and the main regions of forest loss are Amazon rain forest.

Deforestation refers back to the decrease in wooded area areas internationally which are misplaced for different uses such as agricultural croplands, urbanization, or mining sports. significantly accelerated by means of human sports due to the fact that 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate

If forests are cleared, or even disturbed, they release carbon dioxide and different greenhouse gases. forest loss and harm is the cause of around 10% of worldwide warming. there may be definitely no manner we can fight the climate crisis if we do not prevent deforestation.

Forest loss captures  essential influences on woodland cover: deforestation and forest degradation. Deforestation is the whole removal of bushes for the conversion of wooded area to every other land use inclusive of agriculture, mining, or cities and towns.

What explanation describes the primary function of the cell in the table?
svp [43]

Answer: C) The cell can produce energy for cellular functions.

Explanation: A cell is the functional unit of all living things. Cells are made up different parts with specialized functions. Cells take in nutrients from food and convert them to energy which is needed for other cellular functions. The specialized functions of the different parts of a cell can only be carried out if sufficient energy is provided by the cell. The functions of different parts of a cell include reproduction, absorption of nutrients and removal of substances from the cell, protein synthesis but none of these functions will be carried out if energy is not supplied.
