Answer:

Option (A), (B), (D) and (F).

Explanation:

Bacteria are involved in the domains of eubacteria and archaea. Bacteria are different from the other organism and shows different in the chemical and cellular structure of the cell.

The translation elongation factors are different in bacteria and other organisms. The translation factors of bacteria are EF-Tu and EF-Ts whereas the eukaryotic elongation factors are eEF-1 subunit α and eEF-1 subunit βγ. A single RNA pol is present in bacteria and three different RNA pol is present in eukaryotes. Peptidoglycan is present in prokaryotes. Phospholipids contain ester linkage in bacteria and ether linkage in archaea.

Thus, the correct answer is option (A), (B), (D) and (F).

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object? Formula=1/2mv^2 a(7.5 b(15 kg c

Westkost [7]

Hello!

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object?

We have the following data:

KE (Kinetic Energy) = 480 J

m (mass) = ? (in Kg)

v (speed) = 8 m/s

Formula to calculate kinetic energy:

$KE = \dfrac{1}{2} *m*v^2$

Solving:

$KE = \dfrac{1}{2} *m*v^2$

$480 = \dfrac{1}{2} *m*8^2$

$480 = \dfrac{1}{2} *m*64$

$480*2 = 64*m$

$960 = 64m$

$64m = 960$

$m = \dfrac{960}{64}$

$\boxed{\boxed{m = 15\:Kg}}\end{array}}\qquad\checkmark$

Answer:

15 kg

AlladinOne [14]

The correct answer is B. They will become separate species.

This is an example of allopatric speciation.
This means that the two populations of the same species gradually develop into separate species after being separated by a geographical barrier.
In the case of the Astyanax mexicanus, the two populations are separated by the cave.

Explain how DNA supports the theory of evolution?

max2010maxim [7]

Answer:

Because there are tens of thousands of genes in humans and other organisms, DNA contains a tremendous amount of information about the evolutionary history of each organism. ... It determines evolutionary relationships among organisms, and it indicates the time in the past when species started to diverge from one another.
