"Untreated water from a factory flowing into a lake" is an example of point source pollution.
Why? You can actually point to a specific source- the factory. Runoff isn't considered point source.

If I helped you mark brainliest.

Answer: untreated water from a factory flowing to the river.

Explanation: Point source pollution can be defined as the single source by which the polluted water is coming or pollution is coming.

Here the source is factory and the polluted water from the factory is discharged into the lake.This water from the lake can be transferred to other places.

So, the point source is polluted water from factory

Which of the following organelles assembles proteins? ribosomes Golgi apparatus nuclear envelope or endoplasmic reticulum

Artist 52 [7]

The right answer is Ribosomes

The ribosome is a complex composed of RNA and ribosomal proteins, associated with a membrane (in the granular endoplasmic reticulum) or free in the cytoplasm. Common to all cells (prokaryotes and eukaryotes), the ribosome (and especially its composition) varies according to the organisms, even if it is always composed of two distinct subunits.

The ribosome is a huge ribonucleoprotein complex that allows the translation of mRNAs into proteins.

A person will most likely develop aphasia as a result of damage to which parts of the brain?

Anna11 [10]

Answer:

The correct answer is Broca's area or Wernicke's area.

Explanation:

Aphasia refers to a language disorder, which arises due to the destruction of the parts of the brain, which are accountable for language. Aphasia generally causes due to the destruction of Wernicke's area or Broca's area. For the majority of the individuals, these are the sections of the brain's left hemisphere.

The condition known as aphasia generally takes place suddenly, usually as the outcome of a head injury or stroke, however, it can also arise gradually, in the individuals suffering from a brain tumor. The disorder hampers both the comprehension and expression of language and at the same time the tendency to read and write.

Bill the explorer was hiking through the Brazilian rainforest when he came upon a strange, new organism which had yet to be clas

inn [45]

Answer:

Bill should classify the organism as a bird.

Explanation:

It would be right for Bill to classify the newly discovered organism as a bird. This is because the birds are a category of animals which have feathers as well as hollow bones. As for the flying criteria, not all birds belonging to this category can fly. For example, ostrich and kiwi cannot fly but yet still belong to the category of birds, Hence, this newly found organism can be classified into birds as it has feathers and hollow bones.

These are the components of the reservoirs of carbon that are exchanged in our environment. name these components

Marat540 [252]

Answer:

Carbon is a non-metallic and solid chemical element that is found in certain inorganic compounds and in all organic compounds. There are several types of carbons, which are the following:

CRYSTALS

Diamond: by having a SP 3 hybridization, this carbon is the hardest element. It is characterized by having a tetrahedral structure. It is characterized by being a high quality electrical insulator and is also a semiconductor.

Graphite: this material is composed of numerous sheets that have hexagonally located carbon atoms. Thanks to its SP 2 hybridization it manages to conduct electricity.

AMORPHES

A. Natural: these carbons are impure and are the result of the petrification processes of decomposed organic materials.

Coal: this rock has different percentages of carbon ranging between 50% and 80% of its totality. It is characterized by its black being with greasy or matte sheen, it is brittle, extremely hard and consists of compressed lignite.

Peat: This material is characterized by its abundance of carbon, has a rather dark brown color and is composed of compact organic matter. Something that differentiates it from the other materials is that the peat can crumble.

Anthracite: this mineral is the one with the highest amount of carbon, which reaches 95% of its total composition. It has a characteristic brightness and hardness.

Lignite: this has a texture similar to wood, matter from which it comes. It is brown or black and is formed from compressed peat.

B. Artificial: these are stone carbons which depend on their composition and age.

Animal carbon: this material is the result of bones that undergo dry combustion or distillation.

Coke coal: this fuel is acquired from distilled coal that calcites are added to achieve better combustion. This process is carried out in closed furnaces where the fuel is subjected to extremely high temperatures.

Retort coal: this material, widely used in construction, is a good conductor of electricity and heat. It is characterized by its hardness and is found in retort walls of refractory material. In them, coal is distilled.
