Answer: Nitrogen
Explanation:
Harmful algal blooms can occur in lakes, reservoirs, rivers, ponds, bays and coastal waters, and the toxins they produce can be harmful to human health and aquatic life. Harmful algal blooms are mainly the result of a type of algae called cyanobacteria, also known as blue-green algae.
The answer is nitrogen, nitrogen helps algae grow and when it grows in excess it takes away the dissolved oxygen from the water which kills off fish, which puts more nitrogen in the water making algae grow even more until it snowballs and destroys the aforementioned ecosystem.

how can food handlers reduce bacteria to safe levels when preparing vegetables
These can be done by washing of the vegetables, good kitchen Hygiene and proper storage.
Vegetables are perishables, with some quantity of stored water and therefore they harbor bacteria.
Hands should be washed before handling to prevent contamination.Thorough washing should be done under running water to remove the bacteria. The water current sweeps away the bacteria.Further washing of the vegetables in the warm water with 2% saline solution is needed to kill some other bacteria and pesticides resistant to cold water. This is also remove pesticides residue on the leave surfaces.The vegetables should be stored in the refrigerator to slow down the activity of the bacteria prior to cooking or before eating.for more on handling of handling of vegetables to remove bacteria; https://brainly.com/question/4179837

in the ecosystem energy budget, primary productivity is like _____.
Answer: Income
Explanation:
In the ecosystem energy budget, primary productivity is like income. This is because primary production is the way in which energy enters an ecosystem.
I hope this helps :}
In the ecosystem energy budget, primary productivity is like income. Therefore, the correct option is B.
What is primary productivity?Primary productivity is the rate at which organic matter is produced by photosynthesis in an ecosystem. It represents the energy that enters the ecosystem from the sun and is available for consumption by other organisms. Therefore, like income, primary productivity is a source of energy that is available to be “spent” by organisms in the ecosystem.
Option A, debt, is not an appropriate analogy for primary productivity, as it implies a negative balance. Option C, the interest rate, is also not an appropriate analogy, as it does not represent a source of energy but rather a factor that affects the rate of exchange of energy. Option D, spending, is a closer analogy, but it does not capture the fact that primary productivity is a source of energy, rather than an action that depletes energy. Therefore, the correct option is B.

What three things might influence a slide when conditions are right? What types of material can make up a flow? (Site 1).
A slide can be influenced by friction, weight, and the angle of the slope. The materials that form flow generate less friction depending on the environmental conditions.
A slide is a movement that occurs when a fragment of soil/rock suddenly moves down a slope.
Slope stability is a factor influenced by the angle of the slope and the strength of the materials (e.g., rocks) on it.
The slide movement can ultimately be considered as a battle between friction versus gravity.

when preparing pure cultures, dilution is necessary for
Dilution is necessary during pure culture preparation to reduce the bacterial load and allow readable colonies to grow.
Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.
Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.

Aristo was riding in a car and noticed a pond that was covered in algal blooms due to excess phosphorus in the water. Which of these other features in the landscape could be the reason for the high levels of phosphorus? many cars cow pasture solar panels forest.
Algae blooms are caused by an oversupply of nutrients like to water bodies, causing eutrophication. In the exposed example, a reason for the high levels of phosphorus is option B. Cow pastures.
-------------------------
Eutrophication is a biological process produced in water by an oversupply of nutrients or organic matter.
The source of these high nutrient levels, especially nitrogen and phosphorus, are anthropogenic activities.
This oversupply favors phytoplankton multiplication, especially cyanobacteria.
Cyanobacteria can grow in seawater, but blooms mainly occur in freshwater where the salinity level is low.
These algae species that affect freshwater bodies are microscopic, photosynthetic organisms.
Blooms of cyanobacteria reflect the sanity state of water and its abiotic characteristics. They cause severe disasters in water biota and affect human health.
This overgrowth leads to an enhance in primary productivity and reduces the pass of radiation to deeper strata. This fact affects biota in deeper zones.
Gradually sedimentation begins, caused by the death of some vegetable organisms that sink in the bottom.
These sediments suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
Phytoplankton overgrowth on the surface and fermentation process in the bottom, originate toxic compounds that can damage the animals in the water body and humans that get in touch with this water.
Animals die, creating more sediments in the bottom where there are anaerobic conditions.
The lack of oxygen and light continued to increase in decomposition, and fermentation produces a bad smell and toxicity.
Concerning the sources of nutrients that might be causing these events, we can mention, among others, cow pasture.
Cow pasture increases the levels of phosphorous on the ground, which ends in water streams, and from there to ponds or lakes.

A student creates an experiment to determine the effects of oxygen on the growth of a water plant. The student fills three containers with water and adds an aquatic plant to each. Container 1 is open to the air, container 2 has a lid that prevents the exchange of air, and container 3 has a lid with a tube that pumps air into the container. After three weeks, the student observes that containers 1 and 3 have healthy green plants, while the plant in container 2 has not grown, and the leaves show browning areas.
Which explanation provides the reason for the difference in the growth of the plant in container 2?

What safety precautions must I take in a minerals investigation?
Which type of plant would NOT
live on land?
A. alga
B. fern
C. moss
D. roses
Answer:
A. AIga
Explanation:
Alga can live in freshwater lakes or in salt water oceans. Most green alga occur in fresh water, usually attached to rocks and wood.
The ferns are most commonly plants of shaded damp forests of both temperate and tropical zones. Some fern species grow equally well on soil and upon rocks others are confined strictly to rocky habitats.
Mosses are distributed throughout the world except in salt water and are commonly found in moist shady locations. They are best known for those species that carpet woodland and forest floors. Hence, mosses break down exposed substrata, releasing nutrients for the use of more complex plants that succeed them.
Roses typically grow in warm climates and flower in the summer months. However, some roses can grow in the hot tropical climate found in Florida, while others can grow in hardiness zones as low as 2, which have winter temperatures that drop as low as -50 degrees Fahrenheit.
Hence, A. Alga is the correct Answer.
What flower has an ugly bud but a beautiful blossom?
Explanation:
Caladiums are tropical to sub-tropical plants grown mainly for their exquisite, colorful leaves. These foliage plants occasionally have a surprise up their metaphorical sleeve. Blooming on caladium plants isn’t common, but tubers planted in favorable locations tend to produce small flowers. These inflorescences aren’t as impactful as a rose or dahlia but have their own charm and, sometimes, a strong pleasant scent. There are several schools of thought on what to do with caladium flowers. While some growers believe pinching them off helps force energy to the tubers, others leave the small blooms with no ill effect on the plant.
