A person might use a floating g stick to see how fast a ricer flows because when you put th e stick in the water,the stick moves with the water and goes as fast as it does, so when you look at how fast the stick is, you know how fast the water is.
Explanation:
In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems.This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.
Answer:
1 H is consumed in exchanging the synthesized ATP in mitochondria with ADP in cytosol by adenine nucleotide translocator (ANT).
Explanation:
The electrons from NADH and FADH2 are transported in electron transport chain through various complexes that act as electron transporter, to oxygen. In this process, the pumping of protons from mitochondrial matrix to intermembrane space causes a concentration gradient and hydrogen ions diffuses out of matrix space through ATP synthase causing the production of ATP.
3 H are enough to pass through ATP synthase for the phosphorylation of ADP to produce ATP. 1 H or 25% of energy yielded from electron transfer is required to exchange the matrix ATP with the ADP in intermembrane space by adenine nucleotide translocator (ANT). This process provides continuous supply of ADP to mitochodaria and ATP which is exported to cytosol is utilized by cell to perform various functions. There will be no ATP production in mitochondria without ADP. So 4 H are required for 1 ATP production.
1 H for importing ADP to mtichodaria + 3 H for phosphorylation of ADP to ATP
1- Animals survive when they compete. In limited resources, animals either compete, kill or co-operat. There are 3 ways animals complete with each other to get access o limited resources. These ways are:
- Parasitism – In this relationship, one animal gets benefit and the other gets hurt.
- Mutualism – in this interaction, both organisms benefits each other and survives.
- Commensalism- In this interaction, one organism gets benefit whereas the other gets nothing in return.
2- Living organisms are classified as:
- Producers
- Consumers
- Decomposers
Producers are the energy generators. They are the biggest source of energy for other levels. Consumers feed on producers and other animals. And the end, when consumers die, decomposers feed on them, break down their bodies and mix it with soil increase its fertility and the cycle of energy flow goes on.
