Which components bond with andenine in a section if double stranded DNA

Biology
1 answer:
GREYUIT [131]3 years ago
3 0

Answer: 3 and 5 only

Explanation:

Adenine is a purine nitrogenous base and it pairs with thymine which is a pyrimidine nitrogenous base with a triple hydrogen bond in a DNA structure. The adenine binds with thymine directly and indirectly with a deoxyribose sugar which is attached with it in the back it forms the part of sugar phosphate backbone and in the front hydrogen bonding helps in the stabilizing the DNA structure by binding two separate strands of DNA in a stable double helical structure.

9514 1404 393

Answer:

  • time: 1.122 seconds
  • range: 10.693 m
  • maximum height: 1.543 m

Explanation:

<u>Given</u>:

  runner is launched at 30° angle to horizontal at 11 m/s

  acceleration due to gravity is g = -9.8 m/s²

<u>Find</u>:

  runner's hang time

  runner's distance to the landing point

  runner's maximum height

<u>Solution</u>:

The (horizontal, vertical) speed components will be ...

  (11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)

The time of flight can be found from the height formula:

  h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch

The time we're concerned with is the time when h(t)=0 and t>0.

  0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)

The second factor is zero when ...

  t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time

__

The distance to the landing point will be the product of horizontal speed and hang time:

  d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing

__

The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...

  h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height

5. What is the difference between mitochondria and chloroplast?
FinnZ [79.3K]

Answer:

C. Mitochondria convert sugars into energy, while chloroplasts carry out

photosynthesis.

Explanation:

Chloroplasts have the ability to use light to convert carbon, derived from carbon dioxide into sugar. Mitochondria on their part break down simple sugars into carbon dioxide and release energy. Chloroplasts are larger and have greater complexity than mitochondria, and they have several critical functions to perform, besides the generation of ATP. Apart from converting carbon dioxide to carbohydrates they synthesize amino acids, fatty acids, and the lipid contained in their own membranes.

Mitochondria are to be found in both plant and animal cells, whereas chloroplasts are found only in plant cells. The former have a structure composed of a prokaryotic cell, whereas Chlorplasts are made up of stacks of thylakoids surrounded by a fluid called stroma. According to some theories, mitochondria exist because of endocytosis of aerobic bacteria, while chloroplasts are around because of the result of endocytosis of photosynthetic bacteria.

Chloroplasts exist only in plant cells and lend the green color of most plants. Mitochondria on the other hand are found in both animal and plant cells and are engaged in the production of ATP. To use simple layman language, mitochondria in animal cells changes energy into forms that animals can use, while chloroplasts in plant cells convert sunlight into energy that plants can use. From this it follows that mitochondria in a sense are the power plant in the animal cells, because it generates energy. Chloroplasts provide the green color to the plant due to the chlorophyll present in them.

Mitochondria cells are 1 to 10 um long in length. These can change shapes, get around, and divide into two. The cell is surrounded by an envelope of two membranes. The membrane on the outside is smooth while the other one is marked by what are called cristae.

Photosynthesis happens only in plants. This is because only plants contain chloroplasts. Thus we can see that mitochondria and chloroplasts are the building blocks of life for plants and animals respectively in the sense that they provide nourishment to the organisms. The two are also representative of the dividing line between the two kingdoms of life on earth-the animal and the plant.

These two structures are markers of two philosophies of life form if one may use the use the term. One that is self sustaining, manufacturing its own food, the other that is dependent upon the former as the primary source of food, but far more complex and evolved way of life in many other aspects.

Evolution is the
lina2011 [118]

Answer:

Evolution is the <u>biological process</u> that happens over time in a population, giving rise to new <u>species.</u> The theory of evolution states that all organisms alive on Earth today <u>have a common ancestor</u> which lived <u>years ago</u>.

Explanation:

Evolution is one of the fundamental reason of diverse life on Earth today. Principally, this process takes place by changes in genetic elements via mutations and crossing-over. The positive changes (mutations) allow the organism to develop better condition in order to survive in changing environmment. However, if the changes takes place at major scale, it also leads to the creation/development of new species. To explain this further, I have added a photograph where we can see how different organisms were evolved in the history of Earth.
