Answer:

Explanation:

The genetic code dictates which proteins the cell manufactures. ... The sequence of nucleotides in DNA genes determines the order of amino acids in a protein. This is the direct connection between your genes and your traits.

Answer:

Let’s expand to real traits. What determines the subtle shape of a bone, or having five finger buds that make four-boned fingers (the first bone is part of the palm, but one winds up only making two bones (the thumb) that isn’t part of the palm. All five have various muscle attachments passing under the wrist and attaching to specific points along the forearm. And don’t forget that the thumb has extra muscle at the base of the palm.

Each and every detail of making this marvelous structure depends on specific signaling proteins during gestation. How much of a protein exists translates into how far a bud is from the edge, and which edge - - pinky on one edge, thumb on the other. As a general principle, every blood vessel, bone, organ, muscle, tendon, tooth bud, and I’m just scraping the surface here, takes a shape that is pre-programmed by specific proteins, made by specific genes, in a subtle “how much of this specific protein is nearby” dance with thousands of proteins that interact in a mind-blowingly sophisticated dance.

Creationists refuse to accept that six hundred million years is enough time to evolve something so utterly marvelous, especially when they misunderstand that evolution doesn’t happen in discrete steps, it oozes.

Species-level change happens that slowly.

It oozes.

And 600 million years after that chordate animal with four fins, each having one (two?) long stiff bones and five twig-bones on the end, today we have bats and chimpanzees and homo erectus. Or as Barbra Striesand sang in one of her early numbers (in a child’s voice) “Lions and tigers and bears, Oh my!”

With a huge vocabulary, developed very very slowly over hundreds of millions of years, genes can express blueprint-level information, and all of it based on proteins.

g In the elimination reaction of t-butanol and t-butyl bromide. A. They have a common intermediate and require a strong base B.

11111nata11111 [884]

Answer:

Both reactions share a common intermediate and differ only in the leaving group

Explanation:

The elimination reaction of tertiary alkyl halides usually occur by E1 mechanism. In E1 mechanism, the substrate undergoes ionization leading to the loss of a leaving group and formation of a carbocation.

Loss of a proton from the carbocation completes the reaction mechanism yielding the desired alkene.

In the cases of t-butanol and t-butyl bromide, the mechanism is the same. The both reactions proceed by E1 mechanism. The leaving groups in each case are water and chloride ion respectively.

Light from three different lasers (A, B, and C), each with a different wavelength, was shined on the same metal surface. Laser A

kenny6666 [7]

Explanation:

It is known that each metal has a different work function and it is just the energy required to remove the electron from the surface.

The relation between energy and work function is as follows.

$\Delta E = Q + K.E$

where, $\Delta E$ = energy of photon

Q = work function

K.E = kinetic energy of electron

When the value of Q is large then the amount of energy required by the photon is also large and vice-versa.

And, when there is not sufficient energy to remove an electron from metal surface or energy is less than its work function then electron will not be removed.

On the other hand, when incoming photon will have enough energy then electron will be ejected.

In the given situation, light from laser A is not able to remove the electron from metal surface which means that energy of photon is less than work function Q.

As, both B and C are able to remove electron from the surface of metal. So, after the removal of electrons rest of the energy of photons is transferred to eject electrons and this energy is converted into kinetic energy.

As energy of B is greater than the energy of C and A has the lowest energy among all.

Therefore, order of energy from lowest to highest is as follows.

A < C < B

Now, the relation between energy and wavelength is as follows.

E = $\frac{hc}{\lambda}$

where, $\lambda$ = wavelength

So, energy is inversely proportional to wavelength. Therefore, increase in energy means decrease in wavelength.

Therefore, increasing order of wavelength is as follows.

B < C < A

Which of these equations is balanced?

aev [14]

B is the answer. For an equation to be balanced there must be the same amount of each element on the two sides. The only one where this is the case is B.
