Answer:
The energy is recycled
Explanation:
This energy is taken by decomposers such as bacteria and fungi and scavengers such as vultures. The biomass is converted to other biomolecules/biomass by these organisms. However, the process is not 100% efficient. Some of the energy is lost as heat.
B. Both Technicians A and B wrong answer
C. Technician A only
D. Neither Technician A nor B
p.s "both"is wrong
Answer:
C. Only tech A is correct
Explanation:
Oil control rings are designed differently than compression rings. A typical oil control ring consists of three separate pieces: two very thin metal rings called scrapers, and a spacer ring called an expander placed in the groove between them.
the transfer of heat continues, which of the following can be expected
to occur over time?
The Earth’s crust will become less stable.
The Earth’s outer shell will get softer.
Volcanic activity will increase.
The continents will continue to move around.
Answer:
D or the last answer.
Explanation:
The continents will continue to move around because of the heat on the earth, that's why they will also continue to shift over time.
The right answer is that a strongest bugs were able to survive pesticides, reproduce and create more resistant pests.
Pesticide resistance is a hereditary trait that gives an organism the ability to survive pesticide application at lethal doses for most individuals of the same species.
This resistance, manifested by the absence of inhibition, or reduced inhibition, of the development of a population of pests, may be natural or acquired.
* It is natural if the phenomenon is observed from the first application of a pesticide.
* It is called "acquired" if the phenomenon is observed only after several applications of a pesticide, as a result of the selection over several generations of naturally resistant individuals.
Harmful species develop resistance to pesticides through natural selection: the most resistant specimens survive and transmit their genetic traits to their offspring.
When she plays football, she uses more energy than usual.
Some of her body systems work faster than normal.
Task:
Describe what happens to her circulation system and her breathing
system when she plays football. Explain why these changes happen.
Draw diagrams to help explain your ideas.
Keywords to include: respiration, heart, lungs, oxygen, carbon dioxide,
alveoli, inhalation, exhalation, diffusion, red blood cells (13 marks)
Answer:
Firstly, when we exercise, or do some activity (in this case football), we use more energy than usual...
The reason some of her body systems work faster than normal, is to keep the body working and in the equilibrium, so that she won’t get tired too fast.
Related to circulation, her blood flow increases, since she needs more oxygen to reach the muscles faster, due to the exercise/activity (Lactic acid builds up, so more oxygen is required.)
Her breathing increases to take in more oxygen(O2), and give out more carbon dioxide(CO2).
Her body respires more(respiration), both aerobically(with oxygen), and anaerobically(without oxygen), lactic acid builds up due to anaerobic respiration.
(Here, energy is released from glucose to generate a substance called lactic acid. ... Therefore anaerobic respiration cannot be used for a prolonged period of time without having damaging effects on a cell.)
When she inhales (Oxygen), it goes to the lungs, to the alveoli ( Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going)
In the Alveoli, diffusion takes place, this is where oxygen is diffused into the blood, and carbon dioxide is diffused (taken into) into the lungs.
Then we exhale, which gives out the carbon dioxide(CO2), this happens really fast, we also breathe so fast, this process happens within seconds.
Red blood cells contain something called haemoglobin, this combines with oxygen To form oxyhaemoglobin, then when the red blood cell reaches the muscle, it gives the oxygen, converting oxyhaemoglobin back to haemoglobin.
Heart: pumps blood faster (as I said before), to ensure oxygen gets distributed faster to where it’s needed
