Answer 1

Explanation:

Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

Hope this helps :)

The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?

Answers

Answer:

9 amino acids

Explanation:

A segment of a gene that has 27 nucleotides will code for 9 amino acids.

Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.

number of amino acids = number of nucleotides/3

27/3 = 9 codons/amino acids

What height in meters must the student climb in order to reach the top of the hill?

Answers

Answer: 256 or 300 sorry if i was incorrect

Explanation:

The student must reach the top of the hill, and this is entirely dependent on the hill's elevation, which varies from one area to the next and is not constant in any particular area.

What is the significance of the hill in the ecosystem?

The hill is the highest point on Earth and plays an important role in ecosystems because it can provide a variety of different habitats for plants and animals as well as act as barriers that separate different ecosystems, such as the forest ecosystem present on one side of the hill from the grassland ecosystem present on the other side of the hill, and it is also a depositary of minerals and other resources.

Hence, the student must reach the top of the hill, and this is entirely dependent on the hill's elevation, which varies from one area to the next and is not constant in any particular area.

Whether its in losing weight learning the guitar,speed reading, or starting our own business. For those of us who have triedand failed, success seems elusive. Why is it one person succeeds where anotherpersonal fails? First and foremost, I believe it is in their mindset. But secondly,I believe that successful people have developed certain habits, either naturallyor through research that the rest of us havent stumbled upon yet.(2) What is important to you? Finding your core values may seem a bit off-topicwhen it comes to success, but creating goals that are in line with your valuesis key to creating intrinsic motivation. Sit and reflect on what you value most.Pick a handful of things and actually write them down. Remind yourself ofyour values every day, and reflect on whether you are honoring those valuesthrough your work.(3) Choose one goal to start. Something large enough that will give you a sense ofaccomplishment, while aligning well with your core values. Focus is key here.The more focused you are on one goal, the higher chance you have of success.Set a date for success. Identify when your hope to achieve your goal. Keepit realistic, while not giving yourself too much time. By setting a time limit, youare making the process more real. Believe fully in your ability to achieve yourgoal. Visualize yourself having completed your goal in the exact time-frameyou have chosen, although finishing early is also acceptable. You dont needto consider the failures that will happen along the way. Success is inevitable.Others may think you will fail, dont let yourself be one of them!(4) Set up negative consequences for missing the deadline. Necessity is the motherof all invention. If you can manage to keep yourself intrinsically motivated,thats great. If not, this will help kick you into gear and keep your eye on theprize. Prioritize the tasks you have in front of you. Dont always do the mosturgent thing first. Pick the task thats the most important. Sometimes theseoverlap, which is nice. By always accomplishing whats most important, youare making clear progress toward your goal.(5) Push yourself. Go out of your comfort zone. This is the best way to learn, andthe best way to make progress quickly. If youre looking for new ideas, beingrisk averse will not help. This takes a lot of self-awareness. Try and beconscious of when you are holding yourself back out of fear. Push yourself tobe courageous, and take that next step. Failure is inevitable when you takerisks, which is what youll be doing if you want to succeed. By its very definition,the desire to succeed at something means you are risking failure. Many peopletend to give up far too early. Use failure. Treat it as a good thing, and marchon!(6) Take time every day to sit quietly and reflect on your values, goals, and progressmade so far. Where have you excelled, and where can you do better. Iseverything you are doing still lining up with your core values? Always look forways to improve. Never stop learning. Know what everyone else is doing,and what everyone else has done, and how they did it. Search wide forknowledge that might help you, and any inspiration that may do the same.Never think you have nothing to learn from others.(a) On the basis of your reading of the above passage, make notes on itsusing recognizable abbreviations (Min. 4) wherever necessary.
