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.
Answers
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.

D. to have only small substances travel across the cell.
Answers

Answers
Ovulation starts when the secretion of Luteinizing hormone (LH) peaks in females.
Ovulation is simply the release of eggs from the ovaries of females. It happens as a part of the menstrual cycles of the female gender.
The release of eggs from the ovary is triggered by an acute rise in the level of LH in females. LH in males stimulates the production of testosterone.

A scientist fills a glass container with water and places an aquatic plant inside the container, then closes the lid and places the
container in direct sunlight. The scientist observes small bubbles on the surfaces of the plant's leaves on days 1 and 2, but no
bubbles on day 3. The scientist concludes that the bubbles were caused by photosynthesis. Which substance should be
added to the water in order for the bubbles to reappear? (1 point)
Answers
Answer: Are there any options? you either add C02 because it has run out gas or you and in minerals that also contain C02.
Explanation: you need C02 to have photosynthesis, so with a closed off lid, the gas is going to eventually run out.
Carbon dioxide should be added to the water in the container in order for the bubbles to reappear in the glass container while placed in sunlight. Carbon dioxide is a component of photosynthesis.
What is Photosynthesis?Photosynthesis is the process by which plants prepare their own food in sunlight and in the presence of carbon dioxide gas. Photosynthesis process takes place in the chloroplast of cells.
Photosynthesis is an anabolic reaction in which carbon dioxide and water reacts in the presence of sunlight which is trapped by the chlorophyll present in the leaves of plant to produce glucose (carbohydrate) and oxygen gas, which is later utilized in the process of respiration.

What effect does increase salinity have on the density of water?
1. No affect unless temperature also changes
2. Decreases density
3. Increases density
Answers
Answer:
3
Explanation:
For example,The density of seawater depends on the content of salt. It is known that the density of salt is 2.165g/cm3, so the more salt, the greater the density of mixed liquid.
Answer:If you know that dissolution of salt only marginally affects the volume of the solution, how would you expect the density to evolve? It should reasonably increase.
Explanation:
at a given temperature, Should salts be dissolved in the water, and the volume remains reasonably constant, the density
. A solute binds water molecules around itself in a coordination sphere, and should a salt be dissolved, both anion and cation must be solvated; hence an increase in solution density with respect to water.

b. Which types of reproduction are followed in sugar cane plant and in mango tree?
Answers
Sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.
Sugar cane is usually reproduce by using asexual reproduction i.e. by the use of pieces of stem of sugar cane called setts that contain at least one node. It is necessary that these cuttings contain a node because when they are placed and covered in the ground, primary roots arise from these nodes.
While on the other hand, the mango trees can be propagated both by sexual and asexual reproduction. Sexual reproduction involves the fusion of male and female sex cells during flowering stage. Grafting, Cutting, Layering and Budding are the asexual means for the propagation of mango tree.
Among these the grafting technique is considered as the most suitable method of vegetative propagation of mango so we can conclude that sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.
