Answer:
Respiration is a process in which energy is released due to the breakdown of glucose molecules with the addition of oxygen forming carbondioxode, water and energy in the form of Adenine tri phosphate (ATP). In respiration process, carbondioxide is released in the atmosphere and oxygen is used for breakdown of food. This carbondioxide is used by the plants in the process of photosynthesis and oxygen is released in the atmosphere which is again used by animals for respiration.
Correct Answer: A). Dissecting microscopes and compound light microscopes
After magnification the object appears larger in size that is measured by the magnifying power. It can be found out by dividing the focal length of the scanning object to the focal length of the eye piece. From the above given option the greatest difference that is found in the magnifying power is between the dissecting microscope and compound light microscope.
Hence, the correct answer would be option A.
Amongst the options provided, the biggest difference in magnification power is between transmission electron microscopes and dissecting microscopes. Dissecting microscopes provide lesser magnification but enable three-dimensional viewing, while electron microscopes offer superior magnification and detail, at the cost of the specimen's life.
Therefore, the correct answer is option b.
The greatest difference in magnifying power lies between b. transmission electron microscopes and dissecting microscopes.
Dissecting microscopes provide lower magnification, typically ranging between 20 to 80 times the object size, and are suitable for viewing larger objects such as tissues (Fig 3.2b). They also offer a three-dimensional view of the specimen.
On the other hand, transmission electron microscopes utilize a beam of electrons instead of light.
This mechanism facilitates much higher magnification and detail while providing superior resolving power. However, this method requires the destruction of the specimen and cannot be used for viewing living cells.

Answer:
The 2 types of behavioral adaptation are migration, and hibernation.
Explanation:
Adaptation of animal is the fitness towards its environment. If an animal can't adapt, it will perish with time. Adaptation may be genetic or acquired. But basically, adaptation is 2 types - physical adaptation, and behavioral adaptation.
Physical adaptation includes the coloring of the body, camouflage activity of an organism. The behavioral adaptation is the respond of the organisms to their habitat. This includes hibernation, estivation, migration, etc.
Some animals are affected by the temperature difference of the environment. Therefore, they adopt some methods to survive in extreme temperatures.
The cold-blooded like amphibians hibernate during winter. They undergo a long sleep during cold weather and become active in summer. Similarly some animals like desert lizard active in the morning. When the temperature increase they burrow themselves under the ground. This is called estivation.
Birds migrate during the adverse season i.e. in winter. They temporarily go to a different place to spend the cold month and return during the advent of summer. This is one type of behavioral adaptation. They also migrate for better breeding ground and food.
Some fishes also migrate for breeding and food.
Answer:
The substrate uptake rate depends not only on its concentration but also on other environmental factors (temperature, toxicity, pH, etc.) and on the state of cells, what particular transporters are expressed and take part in nutrients consumption.
Answer:
VERY SLOWLY.
Explanation:
When he air we breathe is readily saturated with water, the sweat on your skin can't evaporate. This state of the body will leave you feeling sticky and warm, in as much as the body tries to cool down. High humidity in hot weather will only worsen your discomfort, as the moisture simply sits on your skin unable to evaporate.
In the effort to cool, our bodies must work even harder. This leaves our body to excessive sweating, depth of blood circulation, increased rate and also increased respiration.
