An algal bloom can have a drastic, and often detrimental, impact on ________ biomes.
omeli [17]

Fish and other aquatic life may have a harder time finding food as a result of algae blooms, and whole populations may move away or even perish as a result.

Thick, green muck produced by harmful algal blooms has an adverse effect on clear water, leisure activities, companies, and property values.

  • The process of eutrophication, which happens when the environment becomes enriched with nutrients, increases the quantity of plant and algae development in estuaries and coastal waters, is what causes harmful algal blooms, dead zones, and fish kills.
  • The excessive growth of algae in water bodies is referred to as eutrophication.
  • Algal blooms are what are known as these phytoplankton masses or blooms.
  • Blue-green algae blooms (also known as cyanobacteria, contaminated water supplies, and hypoxia are some of the known effects of cultural eutrophication.

How are vascular and non-vascular plants different, and how do each of them work through osmosis?
Lilit [14]

Answer:

Explanation:

Vascular plants have tubelike structures that carry water, nutrients, and other substances throughout the plant. Nonvascular plants do not have these tubelike structures and use other ways to move water and substances.

Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues. Non-vascular plants do not have true roots, stems, or leaves and the tissues present are the least specialized forms of tissue. Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses. Some examples of non-vascular plants include moss, algae, liverwort, and hornwort.

How vascular plants work through osmosis

The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots to the rest of the plant. Through the xylem vessels, water enters and leaves cells through osmosis.

How non vascular plants work through osmosis

Because non vascular plants do not have the xylem and phloem ystem, they absorb water right into their cells through their leaves when it rains or when dew falls. Internal cells get their water by passive osmosis. While, they use rhizoids to transport nutrients and minerals.

Which microscope did Anton van Leeuwenhoek use to observe single-celled organisms?
likoan [24]
<span>Anton van Leeuwenhoek learned to grind lenses ( 1668) and develop simple microscopes.

</span>

Leeuwenhoek heated the middle of a small soda glass rod , over a flame. On pulling apart the two ends, the glass rod elongated into thin whiskers . 
Heating the end of this whisker resulted in a tiny high quality glass sphere. These glass spheres then became the lens of his microscope, with the smallest sphere providing the greatest magnification.

Leeuwenhoek's designs were very basic. The body of the microscope was a single lens mounted in a tiny hole on a brass plate. The specimen was then mounted on a sharp point that sticks up in front of the lens. It's position and focus could be adjusted by turning the two screws.

The entire instrument was about 3 to 4 inches long and had to be held up close to the eye, requiring good lighting and great patience to use.

Shkiper50 [21]

Answer:

Option 3, of the abiotic factors found in their environment

Explanation:

The abiotic factors such as absence of sunlight and extremely cold temperature represents picture of an extreme habitat under an ice shelf in Antarctica.  

The optimum temperature requirements of bacteria for its survival ranges from 10oC to 20oC. In case,  if a bacteria lives in an environment where temperature is less than -5oC or higher than  50oC, then such habitats are considered to be “habitats with extremities”  as special physiological mechanisms are required to maintain the homeostasis and survive.

Likewise absence of sunlight further adds to the extremities of the habitat.

Option 3, is correct

mafiozo [28]

Answer:

B. Habitat

Explanation:

Habitat destruction is the process by which natural habitat is damaged or destroyed to such an extent that it no longer is capable of supporting the species and ecological communities that naturally occur there. It often results in the extinction of species and, as a result, the loss of biodiversity.
