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.

when preparing pure cultures, dilution is necessary for

Answers

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.

What three things might influence a slide when conditions are right? What types of material can make up a flow? (Site 1).

Answers

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.

Why do cells have a high surface area to volume ratio? *
A. to contain more nutrients
B. to contain more organelles
C. to more readily exchange substances across the cell.
D. to have only small substances travel across the cell.

Answers

Answer: C

Explanation: Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

Which type of plant would NOT
live on land?
A. alga
B. fern
C. moss
D. roses

Answers

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.

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.
