What is algae bloom?
Svet_ta [14]
<span>Algae bloom or algal bloom is an obvious appearance or rapid increase and accumulation of millions of algae and tiny plant-like organisms in the water. The blooms of these microscopic algae or phytoplankton is the result of abundant sunlight, nutrients, and the right water conditions.  These blooms may take place in freshwater and in marine environments as well. They come in different colors, cyanobacteria blooms for instance are often blue-green which literally means that blue-green algae comes to bloom</span> .

Astronomers use __________ to remotely identify the ________ of an object by the unique pattern of lines in its spectrum.
Aliun [14]

Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.

Infrared spectroscopy helps to identify the atoms and molecules in the object.

The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.

The Doppler shift enables astronomers to discover extrasolar planets.

As a planet orbits its star, the star is alternately moving away from or toward us.

Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.

What is true of lithospheric plates?
klemol [59]

Answer:

A. They are constantly moving. I think.

Explanation:

Each lithospheric plate is composed of a layer of oceanic crust or continental crust superficial to an outer layer of the mantle. Containing both crust and the upper region of the mantle, lithospheric plates are generally considered to be approximately 60 mi (100 km) thick. Earth's tectonic plates may have taken as long as 1 billion years to form, researchers report today in Nature. The plates — interlocking slabs of crust that float on Earth's viscous upper mantle — were created by a process similar to the subduction seen today when one plate dives below another, the report says. A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.

A stem cell that has the potential to differentiate into any cell derived from either the endoderm, ectoderm, or mesoderm lineag
dlinn [17]

Answer:

Totipotential.

Explanation:

There are different cell potencies. A <u>totipotent</u> cell is a stem cell that can divide itself and <u>differentiate in any cell </u>that the organism needs. That is to say, endodermal cells, ectodermal cells, mesodermal cells, or extra-embryonic tissues. As cells differentiate themselves, they can gradually lose their potential. The cell's category that follows is pluripotent cells. These are stem cells that can only differentiate into ectoderm cells, endoderm cells, or mesoderm cells. Then we have multipotent cells, which differentiate into tissue cells. The next category is oligopotent cells. They give a limited number of specific cells, and lastly unipotent cells, only differentiate in one type of cell.
