“the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment”.
Answer:
It will become less negative
Explanation:
When a train moves in a direction with decreasing velocity , then it is for sure than acceleration is also decreasing. With stowaways in between before 1 KM of completion of the journey will bring the vehicle in a situation where it will have negative acceleration. Now it is given that force remains same , then with constant mass it is the acceleration which has to increase in order to justify the equation
Since the acceleration was already negative, an increase in acceleration will make it less negative
Explanation:
DNA gyrase is an VERY important bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA. Gyrase categorized to a class of enzymes known as topoisomerases that are involved in the control of topological transitions of DNA. The mechanism by which gyrase is able to influence the topological state of DNA molecules is of inherent interest from an enzymological standpoint. Much attention has been focused on DNA gyrase as the intracellular target of a number of antibacterial agents as a paradigm for other DNA topoisomerases. Current knowledge concerning DNA gyrase by addressing a wide range of aspects of the study of this enzyme. I hope this makes sense to you!
Question 1: The correct answer should be the one that shows the producer first, (->) followed by the herbivore, (->) with the carnivore last.
Producers are organisms that harvest their own 'food' using things like the sunlight and water. Examples of producers are grass and other vegetation.
The herbivore, or an organism that consumes only vegetation and/or algae, consumes the producer.
⇒
The carnivore consumes meat, or other animals such as the herbivore. It's the last.
⇒
⇒
Therefore the answer is
B.

Question 2: I'm pretty sure that succession as well as regrowth after volcanic eruption (Just look at Mount St. Helens. After 30-35 years after the eruption, nature is
still recovering) happens over time/slowly. I would say global warming [C](?) would be the answer.
The digeorge syndrome is a genetic disorder, which caused by the deletion in the chromosome number 22. This disease is characterized by the congenital heart disease, immunodeficiency, and hypocalcemia.
In this case, the most frequent clinical manifestation is hypocalcemia. Hypocalcemia is the condition, in which the blood calcium level would be declined to a significant level.
