Answer:
The algae provide food for fishes and other organisms, leading to decreased algae populations
Explanation:
Excessive nutrients lead to algal blooms and low-oxygen (hypoxic) waters that can kill fish and seagrass and reduce essential fish habitats. ... Eutrophication sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants.
A population of a certain kind of fish is introduced into a new habitat. These fish have variations in color from light to dark. Because of the lighting conditions and predators in this new habitat, light colored fish survive better near the surface and dark-colored fish survive better near the bottom. What change would likely result after many generations of these fish living in this environment
Answer:
There would be two populations of fish:
Light-colored fishes near the surface
Dark-colored fishes near the bottom.
Explanation:
After many generations, there would be two populations of fish: Light-colored fishes near the surface and Dark-colored fishes near the bottom as light-colored fish survive better near the surface and dark-colored fish survive better near the bottom due to the lighting conditions and predators in the new habitat.
1. What does the dermal tissue system do?
Answer:
Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots). Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss.
Describe las diferentes características que puedas observar entre los dos ejemplos¿A qué tipo de roca pertenecen?
Nota: Imagen de las rocas en archivo adjunto
Answer:
A- Roca sedimentaria
B- Roca Ignea
Explanation:
A- Características: A simple vista pareciera ser una roca con restos fósiles sedimentados, de colores opacos en los tonos de los marrones. Pareciera ser una roca sedimentaria. Las rocas sedimentarias se forman por acumulación de sedimentos en capas, uno sobre otro, incluyendo dentro de estas capas restos animales o vegetales que quedan incrustrados. Una vez tapados por mas capas, a medida que pasa en tiempo, los restos se van fosilizando y las capas se sedimiento se van solidificando hasta formar una roca.
B- Características: A simple vista se pueden observar distintos colores: rosa, blanco y negro. Entre estos tres, el rosa es el color que predomina. Cada color, correspondiente a un mineral, se observa en forma granular. La textura de este elemento parece ser suave, lo que indica un uso industrial y consecuente importancia económica. Puede tratarse de una roca de granito, de orígen igneo intrusivo. Conformadas principalmente por cuarzo y feldespato, de granos visibles a simple vista. Pueden observarse tambien otros minerales presentes. Por esta composición de minerales, la roca adquiere coloración general rosa, gris o blanca. El cuarzo da color blanco. El feldespato, predominante, puede dar colores claros a rosa salmon en distintas tonalidades. Otros compuestos pueden aportar colores oscuros como el que se oberva en la foto.

Darwin's scientific theory of evolution explains and predicts which of the following?
A Species change over time.
B
Extinct species are NOT related to living species.

Nuclear fusion
Plants
?
Plant life decay
Answer:
A. Hydropower(Water cycle)
B. Plants(Photosynthesis)
C. Sun(Nuclear fusion
D. Fossil fuels(Plant life decay)
Explanation:
Hydropower can be regarded as water power which as a result of energy gotten from running water i.e water cycle
Plants are multicellular organisms and they can produce their food on their own, they utilize the process of photosynthesis.
Nuclear fusion involves coming together of two atomic nuclei , energy is involved
.
fossil fuel is one that is formed as a result of decomposition of dead organisms of many years and it involves some cycle of plants or animals decay
Answer:
hydropower = water cycle
sun = nuclear fusion

What is the difference in the shape of a muscle tissue cell and a nerve tissue cell?
Answer:
The shape of a nerve cell in a nerve cell in an animal is different from the shape of a muscle cell. A nerve cell is long and branched whereas a muscle cell is pointed at both ends and has a spindle shape.
Muscle and nervous tissues rely on electrical activity to function. Muscle tissue generates force to provide movement, and nervous tissue is responsible for transmitting electrical and chemical signals throughout the body. Muscle and nervous tissues are considered excitable tissues.

For stars in the main sequence, which color of stars tend to have higher absolute brightness? (2 points)
The HR diagram is shown with Absolute Brightness on the y axis from negative four to six and Surface Temperature on the x axis from 40,000 to 2,500 degrees Celsius. There are several dots plotted between four and six absolute brightness and 10,000 to 2,500 degrees Celsius labeled Supergiants. There are several dots plotted between 1.5 and three absolute brightness and 7,500 to 2,500 degrees Celsius labeled Giants. There are several dots plotted between negative four and negative two absolute brightness and 30,000 to 7,500 degrees Celsius labeled Dwarfs. Down the middle, there are several dots plotted diagonally from ordered pair 40,000 and five down to 2,500 and negative three labeled Main Sequence.

Answer:
Blue Stars
Explanation:
Hope this helps :)
Blue stars tend to have higher absolute brightness for stars in the main sequence.
What is absolute brightness?Absolute brightness, also known as absolute magnitude, is a measure of the luminosity of a celestial object such as a star or planet, expressed as an apparent magnitude that the object would have if it were placed at a standard distance of 10 parsecs (32.6 light-years) away from Earth.
It is an objective measure of an object's intrinsic brightness, independent of its distance from Earth. Absolute brightness is a useful tool in astrophysics for comparing the luminosities of stars and determining the distance to remote stars and galaxies. It provides a standardized method of comparison, allowing scientists to study the evolution and distribution of stars and galaxies throughout the universe.
