A scientist is extracting the DNA of a multicellular organism. He finds that 20% of the strands bases are Thymine. Based on Chargaff's rule, what percentage of the
strands bases would be Adenine?

A. 20%
B. 70%
C. 40%
D. 60%

Answers

Answer:

A. 20%

Explanation:

A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.

Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.

A + T + G + C = 100%

Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S

Since A=T = 20% in accordance to Chargaff rule.

2. What does letter B represent on the Earthquake model?

A:Epicenter
B:Focus
C:P wave
D:O S wave

Answers

Answer:

A.

Explanation:

The letter B represents the Epicenter of the earthquake.

The focus would be the letter A and C would be called the fault.

The epicenter is the point closest to the point where the earthquake originated but on the surface and not underground. The hypocenter is the point within the earth where an earthquake rupture starts.

There are two forms of diabetes. Type II diabetes is also known as late-onset diabetes because it typically affects adults. Consider the following information about Type II diabetes:

Studies have shown that the lifetime risk for developing Type II diabetes is 40% for individuals who have one parent with Type II diabetes.
If a person has two parents with Type II diabetes their risk rises to 70%
Other factors that affect your risk for Type II diabetes include obesity, a sedentary lifestyle (not moving around much), a small or large birth weight, and stress.

Use the information above to answer the question: Is your risk of having Type II diabetes due to your genes, or due to the influence of the environment on your genes (epigenetics), or both?

Answers

Answer:

Both

Explanation:

As explained in the passage wether your mom or dad or both have had type ll diabetes in the past determines your risk of having it as well which is part of your genes. But also the influence of the environment on your gene is also a cause to type ll diabetes . Some people would rather stay inside rather than get exercise or some people would rather eat candy or sweets for breakfast or dinner all these things are causes of type ll diabetes which they are caused by the influence big the environment on your genes.

Erythrocytes (red blood cells)have no nucleus, mitochondria, orother organelles at maturity. Theseorganelles are ejected when the RBCenters the bloodstream, or shortlythereafter. Should this still beconsidered a cell? What will be theeffect of having no nucleus? In thesecells, the lack of mitochondria is anadvantage. Why?

Answers

Answer:

Erythrocytes are not considered true cells, because of their lack of a nucleus. The effect of having no nucleus makes their self-reproduction impossible, and the absence of mitochondria is a disadvantage because they have to obtain energy by alternative reactions.

Explanation:

Erythrocytes, or red blood cells, are the structure in charge of transporting gases in the blood. When these cells are mature, they have already lost their nucleus —in order to have space to house the hemoglobin molecule— which prevents mature red blood cells from being able to reproduce.

Additionally, red blood cells do not have mitochondria —the main energy generator in eukaryotic cells— so in order to obtain energy they need to perform lactic fermentation, with a lower enegetic yield, which may be a disadvantage, but sufficient for this structure to perform its function.

Life coaches, business coaches, We may or may not take them seriously, but we must know something. Most, if not all of them, be it famous ones or not-so-famous ones, agree at one valuable point: goals are crucial. Short-term as well as long-term goals are the key the achieving a more successful life.What professionals such as Tony Robbins claim is that having goals will provide you with a direction in life. The steps you take will gain value as to whether or not they take you any closer to those goals. If they dont, the best thing to do would be to evaluate how they can be changed or even left out and substituted for more efficient ones. Robbins, continually tells the story of how he wrote down every single thing he wanted to achieve in life along with the actions he would take to do so and how he did indeed achieve all of those things.When it comes to landing that beautiful and profitable a dream job, setting a long-term goal can undoubtedly direct your actions. If you choose to focus only on the short-term aspects of work and professional development, odds are that you will end up near-sighted. You will only work hard at things that can bring you immediate compensation. Those things are not naturally going to land the dream job. They will keep you alive, pay bills, and buy some food, but wont necessarily satisfy the requisites to get to the top, whatever that can mean to you.If you do choose to have a long-term goal that is dream-job related, the chances are that you will choose different paths. You will not see that ten-month course as a waste of time, since it will give you useful skills. You will spend your money more wisely, viewing it more as an investment than as a necessary evil. You will gain a new perspective of what time means and develop the sense that immediacy is overrated.There are those who call themselves realistic or, more honestly, pessimistic. They may claim that setting long-term goals is nothing but a recipe to feeling like a failure. Truth be told, it is indeed possible that you wont achieve every single thing you wish for, which is actually in most cases for us that we don't necessarily achieve our every goal. It might be our lack of willpower or that our goal was just not engineered very well. So that is a reality not only for you but for everyone else on this planet. However, not achieving something should not be a synonym for failure. It can mean some rethinking is important, some assessing needs to be done, a new plan should be concocted. Great minds goals, such as Elon Musk, are not only long term but also ambitious. And if they fail on their way, they find the means to try again, now with improved knowledge from the previously failed experience.Tony Robbins says that most people overestimate what they can do in a year, and underestimate what they can do in a decade. That is the real recipe for failure: seeing time as a factor of stress and pressure instead of an ally. By giving yourself a grand goal and a good amount of time to do it such as landing the dream job in five to ten years, you are being more realistic than you would be by either giving up altogether or trying to do it impossibly quickly. Landing a dream job takes time and effort, but as long as you set good reasonable goals, you can accomplice almost anything.
