Answer:

Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Algae can be multicellular or unicellular. Unicellular algae occur most frequently in water, especially in plankton.

The pictures below show two processes. (4 points)
Evgen [1.6K]

Answer:

  • Both processes form minerals.
  • Volcanic eruptions form precipitates and shifting of tectonic plates form minerals.

Explanation:

Both volcanic eruptions and the shifting of tectonic plates form minerals. Volcanoes and their eruptions can directly or indirectly lead to the formation and/or deposit of minerals such as diamonds and zinc. Shifting also forms minerals due to the forces of compression the plates apply on each other as they move past.

Volcanoes are known the cause precipitates because when the erupt, the ash that is released mixes with water vapor which then becomes rain eventually.

A researcher discovers a new prokaryote that lives on the seafloor near hydrothermal vents. This organism reduces CO2 to form C6
expeople1 [14]

Answer:

D. Chemoautotrophs

Explanation:

Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.

Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.

Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.

Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.

Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.

Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.

Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.

A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N
Paladinen [302]

Answer:

The box will not move because balanced forces are acting on it.

Explanation:

According to Newton's first law of motion, an object will remain in its state of rest or motion along a straight line unless acted upon by an unbalanced force.

An unbalanced force is an individual force acting on any side of an object which is not balanced by a force of equal magnitude acting in the opposite direction.

From the image, two forces of equal magnitude of 10 N are pulling the 100 kg box in opposite directions. Since the two forces, 10 N each are pulling the object in opposite directions, they are balanced forces. Therefore, the box will not move because balanced forces are acting on it.
