Kate and Sam are using a scanning electron microscope to study photosynthesis in algae. Which is a benefit of this type of microscope compared to
a light microscope?
Answer:
B. Produces highly magnified images
Explanation:
Trust me
Kate and Sam are using a scanning electron microscope to study photosynthesis in algae, and the benefit of using this type of microscope rather than a light microscope is that the scanning microscope gives clearer details of the process.
What are the benefits of using a microscope?The microscope gives a better view of the smaller things, and there are different types of microscopes, such as the light microscope, the electron microscope, etc., and other high-quality microscopes that are helpful for the better viewing of the samples. The light microscope has a lower magnification range than the electron microscope, and the species can be better viewed in the electron microscope. Depending on the application, different microscopes should be used, and photosynthesis can be seen better in a scanning microscope than in a light microscope.
Hence, the benefit of using this type of microscope rather than a light microscope is that the scanning microscope gives clearer details of the process.

Compare and contrast the burning of a Cheeto with the cellular respiration that
happens in your body.
Answer:
Cellular respiration is similar to combustion because both reactions rely on fuel (reducing and oxidizing agents) to start the reaction; the difference is that in cellular respiration, enzymes are used during the reaction. Both result in smoke (CO2 and H20) and energy.

Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.
Answer:
How the structures of plant tissues and organs are directly related to their roles in physiological processes.
o Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.
o Physiological processes are limited to photosynthesis, cellular respiration,
transpiration, and reproduction.
o Plant tissues are limited to meristematic, ground, dermal and vascular tissues.
o Plant structures are limited to cambium, guard cells, phloem, seed, stomata and
xylem
Explanation: Hope this helps have a safe and happy new year
Roots, stalks, leaves, flowers, fruit, and cones are the only organs found in plants. Photosynthesis, metabolic processes, transpiration, and fertilization are the only physiological activities.
Plant and plant tissues:Photosynthesis and the movement of mineral-containing water ions are critical processes in the development of healthy plants. Plants have three primary structures or organs:
LeavesStemsRootsThey're made up of groupings of specialized tissues with structures that are tailored to the functions they do.
Adaptations are distinctive features that help plants survive in their specific settings. Plants rely on their specialized structures to provide their fundamental requirements, protect themselves from predators, and aid reproduction.

Please help this is due at 11:59 tonight!!! Jimmy and Jenny have designed an experiment to test how termites react to the chemicals in ink pens. They use one termite in their experiment. Jenny draws four circles, using four different brands of black ink. Jimmy places the termite on each circle of ink and they watch the termite's behavior as it is placed on each circle, one try per circle. In all four cases, the termite veers off the ink circle. Jimmy and Jenny conclude that termites are not attracted to ink at all. What suggestion would you give Jimmy and Jenny concerning their experimental design?
A. Compare the termite’s behavior on ink circles to the behavior on pencil circles.
B. Run repeated trials with the one termite.
C. Use more than one termite and run many trials.
D. Use more than one termite and the same brand of ink pen each time.
Answer:
Use more than one termite and run many trials.
Explanation:
it's not A because we're not trying to figure out pencil's but the chemical's in ink. It's not B because using just one bug wouldn't really get us anywhere. It's not D because you'd actually want to try different brands of ink to see if maybe you had a lesser chemical ratio. It's C because not all the bugs will react in the same way as just one would. Also, doing multiple trials would show us if they would change their behaviors.

Energy conversion within a plant cell would be limited most severely by removal of the cell's - A mitochondria B chloroplasts C ribosomes D endoplasmic reticulum
Answer:
The answer is Mitochondria. I took the test and that's the correct answer.
Energy conversion within a plant cell would be limited most severely by removal of the cell's by mitochondria.
What is mitochondria?Mitochondria are membrane-bound organelles (mitochondrial, singular) that produce most of the chemical energy required for biochemical reactions in cells.
The chemical energy produced by mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Mitochondria contain their own small chromosomes. In general, mitochondria, and thus mitochondrial DNA, are inherited only from the mother.
Therefore, Energy conversion within a plant cell would be limited most severely by removal of the cell's by mitochondria.

Explain how the farms upriver were adding to the high nitrate levels. gizmo
Answer:
Farmers were adding high nitrate levels from many large corn farms along the river. The farmers spray fertilizers that have ammonia and nitrate onto their crops. During the drought, the farmers used extra fertilizer. As rained, the ammonia and nitrate from the fertilizer were washed into the river.
In the pigs produced 10 pounds of feces that contained ammonia and nitrate. The pit is too small to obtain such large amount. When it rained the waste overflowed in to the river.
Explanation:
The drought from the week before and the large rain fall played a large part in the outcome of the annomia and nitrate exposure to water.
The farms upriver were adding to the high nitrate levels. It was because of the excessive use of fertilizers and inadequate waste disposal techniques.
What are agrochemicals?There are chemicals that are used in agriculture. It includes fertilizers, pesticides, nematicides, insecticides, etc.
How does farm upriver add nitrate?The farms upriver used to apply agrochemicals, especially the ones rich in nitrate and urea. During fewer water conditions they used to apply more. That used to remain in the soil and washed down to the river along with the rain.
The farms did not use adequate waste disposal measures and hence the wastes rich in nitrogen were washed down to the river.
Hence, these practices increase nitrate levels in the river.
