Answer:
It is important that nursery practices are favorable for maintaining physiological processes of seedlings that will result in high capacity for growth and survival after outplanting. ... Production of high-quality seedlings requires close attention to all phases of nursery management.
pls give brainliest for the answer
Answer:
The correct answer is - Both move with constant speed.
Explanation:
If an object moves in a particular way that it covers the same distance at the same times the speed considered as constant suppose if two objects a and b both travel 10 m and 20 m respectively and the time they take in travel are 2 and 4 seconds respectively than we can say they both have a constant speed.
The relation between the variables x,t, and v is
x=v.t
If V is constant which is the speed we get a straight line x-t in the graph.
By the given information we can say that both objects A and B are traveling at a constant speed.
Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
Gravity , Explosion
<u>Explanation:</u>
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.
