Answer: I believe the answer is B. Sorry if i'm wrong
Explanation:
The answer is dnaA, it is a protein that enacts start of DNA replication in microscopic organisms. It is a replication start figure which advances the loosening up of DNA at oriC. The onset of the start period of DNA replication is controlled by the grouping of DnaA.
Answer and Explanation,
Sand dollar, any of the invertebrate marine animals of the order Clypeastroida (class Echinoidea, phylum Echinodermata) that has a flat, disk-shaped body. They are close relatives of sea urchins and heart urchins. The sand dollar is particularly well adapted for burrowing in sandy substrates. Very small spines used for digging and crawling cover the entire surface of its body and are appressed backwards toward the posterior anus. The mouth is located in the centre of the body’s underside. The upper surface exhibits pentaradiate symmetry, with a pattern of five “petals” spreading out from the centre. Some species found stranded on the shores of North America have five or six slots, or lunules, through the test (external skeleton). Most sand dollars measure from 5 to 10 cm (2 to 4 inches) in diameter. Species of comparable size occur in shallow coastal waters throughout the rest of the world, except in Europe and Antarctica.
Answer:
Explanation:
In one mole of carbon, there are 6.02×10^23 atoms. So in two moles, there will be twice that: 1.204×10^24
Answer:
0.67 atm
Explanation:
From the question,
Applying Boyles law
PV = P'V'......................... Equation 1
Where P = Initial Pressure of the sample of gas, P' = Final pressure of the sample of gas, V = Initial volume of the sample of gas, V' = Final volume of the sample of gas.
make P' the subject of the equation above
P' = PV/V'.................... Equation 2
Given: P = 10.0 L, V = 1.0 atm, V' = 15.0 L
Substitute these values into equation 2
P' = (10.0×1.0)/15.0
P' = 0.67 atm
