As we know there is a certain force called the frictional force that is required in order to resist the movement of a certain object. This frictional force occurs whenever two objects are rubbed against each other. The frictional force generated is converted to heat energy in due time making the surface hot.

all plants give out oxygen during day and carbon dioxide during night. Do you agree with this statement. Give reason
Citrus2011 [14]

This statement is incomplete.

"All plants give out oxygen during day and carbon dioxide during night"

Explanation :

Photosynthesis occurs only during day time.

During this time oxygen is produced . Some oxygen is used for respiration and rest of oxygen is diffused out into air.

Carbon dioxide produced during day time by respiration is used in photosynthesis.

But at night time, no photosynthesis occurs  and hence no oxygen is produced oxygen from air diffuses into leaves to carry out respiration and carbon dioxide produced by respiration diffuses out into air.

Hence Respiration occurs day and night .. Hence Carbon dioxide  is emitted  all the time....

Which statement describes how enzymes and substrates are related? The enzyme influences the speed of change from substrate to pr
azamat

Correct answer: A). The enzyme influences the speed of change from substrate to product

The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.

They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.

Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.

HELP PLEASE!! Field test is done on the milkweed in the wild and the clothianidin content per plant was about 1 ppb. larvae spen
MrMuchimi

Answer:

In the question it is given that the milkweed with clothianidin above the 1ppb concentration will result in less successful hatching of monarch butterfly eggs. Along with the data from the experiments, the exposure of clothianidin on the monarch habitats will lead to a decrease in the population of the monarch butterfly initially. Then in later generations if any mutation occurs and a resistant butterfly is developed then the population of the monarch butterfly will recover. But without this mutation the population size will be reduced and the size and weight of the butterfly will also get reduced.
