no mitochondria; anaerobically
mitochondria; aerobically
no mitochondria; aerobically
None of the above
Answer:
no mitochondria; anaerobically
Explanation:
Red blood cells have no mitochondria and generate energy anaerobic. So, the answer would be B. You can easily eliminate A. and C. because they mention that blood cells have a mitochondria, but they don’t.

Explain how hydrogen fuel cells work, and why they provide a healthy, clean way to produce heat and electricity. (Site 1).
Answer:
As there are no moving parts, fuel cells operate silently and with extremely high reliability. Due to their chemistry, fuel cells are very clean. Fuel cells that use pure hydrogen fuel are completely carbon-free, with their only byproducts being electricity, heat, and water.

describe in detail, the pathway of an oxygen molecule as it moves from the air outside your body, into your blood and to cell in a muscle in your arm
Answer:
The oxygen molecule enters the human body from the mouth or nose and reaches the phraynx and then the larynx, trachea and the bronchus. It then enters the lungs which then the red blood cells takes the oxygen from the blood and carries it to the muscle in the arm.
The pathway of an oxygen molecule from the air outside your body to a muscle cell in your arm involves several sequential steps, including inhalation, gas exchange in the lungs, transportation through the bloodstream, and diffusion into muscle cells.
During inhalation, you breathe in air through your nose or mouth. The air travels through your respiratory system, passing through the trachea (windpipe) and into the bronchi, which branch into smaller tubes called bronchioles. Eventually, the inhaled air reaches the alveoli, tiny air sacs located at the end of the bronchioles in the lungs.
In the alveoli, oxygen molecules diffuse across the thin walls of the air sacs and into the surrounding capillaries. Oxygen diffuses from an area of higher partial pressure (in the alveoli) to an area of lower partial pressure (in the capillaries). Hemoglobin, a protein within red blood cells, binds to the oxygen molecules in the capillaries, forming oxyhemoglobin.

Which of the following does not directly cause erosion?
O Ice
OLichen
ОSun light
oChemicals
Answer:
a ice
Explanation:
ice doesnt cause erosion directly
Photosynthesis takes place in two separate but dependent series of steps:
First, the light dependent reactions and then the light independent reactions.The light independent reactions (AKA the dark reaction/Calvin cycle) of photosynthesis occurs:
A.Only in the dark in plants
B.In the light and dark in plants
C.Only in the light in plants
D.None of the above
Answer:
Your answer wold be B: In the light and dark in plants
Explanation:
In the light and dark in plants is the correct answer
The option (B) is correct. In the light and dark in plants.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Moreover, photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Hence, the primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process. It's not particularly efficient by human engineering standards, but it does the job.

19. Engineer It In some rivers and lakes, dams
are constructed to harvest energy by converting the
kinetic energy of moving water into electrical energy.
Water from behind the dam flows through a turbine
that transforms kinetic energy into mechanical
energy. The turbine turns a generator that converts
mechanical energy into electrical energy.
The water from behind the dam could flow to the
turbine either through an opening near the middle or
top of the dam or by flowing over the top of the dam.
Which type of water flow would be the best design for
sending a consistent flow of water past the turbines?
Explain your reasoning.
Answer:
A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.

btw here u go
Explanation:
in q 1, part a, we need to tell what we observed in the growth of plants. we observed that the plant h was groing faster and healthier that plant g due to the fact that it was provided with a nutritive solution.
in its part b, we write the conclusion, i.e the plant which was provided with a nutritive solution grew more as all minerals required by the plants were replenished properly.
In q2, part a, we just compare their physical properties such as the plant g was not as healthy as plant h and plant h grew faster and taller than plant g.
in q2, part b, we just write what the solution is supplying the plant with, you can also check each one of their speciality on the web and write it also.
