DNA replication occurs during which phase of the eukar<br><br> yotic cell cycle?
Ann [662]

its either The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs or In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important. hope this helped!!

schepotkina [342]

Answer: No

Explanation: It is beneficial if the animals that are disadvantageous doesn't reproduce so it doesn't discredit natural selection. The traits in which variation is occured are more suitable for organism to live and reproduce in the environment are preserved and are passed from generation to generation.

However, natural selection effects limited number of progeny.

You dilute your bacteriophage for plating 10^-6. You mix 0.1ml of the bacteriophage dilution with 0.3ml of bacteria and plate wi
Blizzard [7]

Answer:

46 * 10^7 pfu/ml

Explanation:

Given -

Bacteriophage dilution = 0.1 ml

Volume of bacteria and plate with top agar  = 0.3 ml

Number of plaques = 46 pfu

Dilution (d) = 10^{-6}

Final concentration of phage stock is equal to

= \frac{pfu}{d*v}

Where pfu is the count of plaques

d is the dilution and v is the volume

Substituting the given values, we get -

\frac{46}{10^{-6} * 10^{-1}} \\= 46 * 10^7 pfu/ml

From the big bang theory, after cooling the debris, allowed the formation of the following
galben [10]

Debris (Hydrogen and helium) from the big bang gravitationally clumped together, and frequently these clumps got big enough to start fusion in their centers and form stars.

What is big bang theory?

The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.

Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.

The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode. The remaining hydrogen gas is now "contaminated" by this other material, and some of it forms an accretion disk in which planets form when it compresses under gravity.
