Researchers are investigating the incidence of algal blooms in neighborhood ponds. In summer, they collect water samples from over 100 neighborhood ponds in Dallas, Texas and surrounding cities. They also surveyed residents in each neighborhood to collect data such as average lot size, average home value, average resident income, and lawn care methods. The researchers found that neighborhoods with large lots, high home values, and high income levels were likely to use automatic sprinklers and synthetic fertilizers on their lawns. These same neighborhoods were very likely to have abundant algae in their ponds. Based on this research, which conclusion below provides the best explanation for why algae proliferate in neighborhood ponds?

a. Automatic sprinklers may house algae and may spray into neighborhood ponds.
b. High income neighborhoods are less likely to treat their ponds with chemicals that prevent algae growth.
c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.
d. Neighborhoods with expensive homes typically have larger, deeper ponds that are more likely to support algae proliferation.
e. Large lot sizes likely provide algae with extra room to grow, and the algae then washes into the pond.

Answers

Answer: c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.

Explanation:

Eutrophication is a natural phenomena in which the algal growth occurs in the water body due to increase in concentration of the fertilizers and manures being drained from the agricultural land into water. This causes decrease in oxygen level in water, and the aquatic animals in water will not survive due to scarcity of water.

According to the given situation, the growth of algae in the neighboring ponds is due to the drainage of lawn fertilizers into the neighboring ponds being washed from the lawns. This causes algae to grow abundantly in ponds.

Summarize what reasherchers did to improve the quality of post mining sites soil in

Answers

Answer:

The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.

A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic. The compacted soil after mine proves harder to  bring seed into the soil.

The researchers  try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created “planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.

The photograph shows rockweed. Which feature allows rockweed to
withstand the constant wave action of its environment?
A. The ability to carry out chemosynthesis
B. The ability to firmly attach to rocks
C. The ability to produce its own light
D. The ability to carry out photosynthesis

Answers

Answer:

B

Explanation:

This is the answer because if the rockweed is able to firmly attach its self to the rocks it would be able to withstand the constant wave action

The tendency to firmly attach to rocks allows rockweed to withstand the constant wave action of its environment.

Rockweed

It is a brown alga and grows in the rich intertidal zone.

The holdfast of a rockweed permits it to withstand the constant wave action of its surroundings.

Holdfast is a tiny stem-like composition which allows the weed to anchor firmly to the rocks.

The rockweeds possess some of the advantages over the normal weeds that permits them to sustain in water like the intense developed root systems.

Thus, the correct answer is option B, that is, the ability to firmly attach to rocks.

Prokaryotes are single-celled creatures belonging to the Bacteria and Archaea domains. Eukaryotes include animal cells, plant cells, fungus, and protists. Prokaryotic cells do not have a nucleus. Cells with a nucleus are referred to be eukaryotic cells. Aside from the nucleus, eukaryotic cells have other organelles. Ribosomes are the only organelles in a bacterial cell.

eous rocks are formed?​

Answers

Igneous rocks are formed by the cooling and hardening of molten material called magma . The word igneous comes from the Latin word igneus, meaning fire. There are two types of igneous rocks: intrusive and extrusive. Exam- elation: Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly. Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma . ... This changing of rock types is called the "Rock Cycle". Solid rock can be changed into a new rock by stresses that cause an increase in heat and pressure. A rock is a naturally formed, non-living Earth material. Rocks are made of minerals. The minerals may be so tiny that you can only see them with a microscope.
Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified: magma that cools slowly will form an igneous rock with large crystals. lava that cools quickly will form an igneous rock with small crystals. their visual appearance shows individual crystals interlocked together to form the rock mass. The cooling of magma deep in the Earth is typically much slower than the cooling process at the surface, so larger crystals can grow. Intrusive igneous rocks form in magma chambers that are deep underground. Many kilometers below the Earth's surface, molten rock called magma flows into cracks or underground chambers. There, the magma sits, cooling very slowly over thousands to millions of years. An intrusion is a body of igneous (created under intense heat) rock that has crystallized from molten magma. Gravity influences the placement of igneous rocks because it acts on the density differences between the magma and the surrounding wall rocks (country or local rocks). The most common river rocks used in landscaping and decorative construction are made of granite. Granite belongs to the "intrusive" category of igneous rock, which means it formed below the earth's surface as magma slowly cooled and crystallized. The rocks that form Earth's crust are continually destroyed and remade in an endless process called the rock cycle. Rock is formed by melting; by cooling and solidifying; by changing through heat and pressure; by weathering and erosion; and by compression and cementation.
