5. The first protein produced by

Lady bird [3.3K]

Answer:

when an organism is covered by sediment,it begins to decay, when decaying,the organism releases a gas.This process in turns leaves a thin film of carbon that preserves part of the organisms.The hallow that forms on the sediment is the carbon film that contain fossils of the organism.

f a protein is coded for by a single gene and this protein has six clearly defined domains, which number of exons below is the g

lana66690 [7]

Answer:

The correct answer is C) 8 exons.

Explanation:

If we assume that each domain matches with an exon, and we have a 6 domain protein (domain= the functional regions of the protein that include the active site), there must be at least 6 exons in the gene. Also, remember that exons include the 5'- and 3'- untranslated regions or UTR. So, assuming that each unstraslated region is equivalent to an exon, there must be at least 8 exons in the gene (6 exon for each domain and one 2 exons for UTR).

Anyway, be careful, because this is a simple exercise where we assume a lot of things. In the real world, the first exon tends to include the 5'-UTR and it is already proved that one exon is not always equivalent to one protein domain.

semi anThe bones of a prehistoric man found in the desert of New Mexico contain approximately 5% of the original amount of carbo

Kitty [74]

Answer:

24555 years

Explanation:

Data provided in the question:

Half life of carbon 14 = 5700 years

carbon present in the dead man = 5% of the original amount of carbon 14

Now,

let the initial Amount of carbon be 'A'

Therefore,

after half life

Amount of carbon = $\frac{A}{2}$

Thus,

$\frac{A}{2}$ = $Ae^{kt}$

here,

k is the decay constant

t is the time = 5700 years

therefore,

1 = $2e^{k\times5700}$

or

0.5 = $e^{k\times5700}$

taking natural log both the sides

-0.69314 = 5700k

or

k = - 0.000122

therefore,

for dead man Amount of carbon = 5% of A = 0.05A

thus,

0.05A = $Ae^{( - 0.000122)t}$

or

0.05 = $e^{( - 0.000122)t}$

taking natural log both the sides

we get

-2.995 = - 0.000122 × t

or

t = 24555.18 ≈ 24555 years

Give one example of how classification is used in school

weeeeeb [17]

One way classification is used at school is the separation of different subjects and subject materials. Kind of like, one day you may go to a math class, while another day you may go to a french class.
