Scientists have studied a fruit fly, Drosophila, to better understand early embryonic development and have discovered that the cell cycle changes as embryonic development proceeds. Model A represents the first 13 cell cycles after fertilization, which only includes two phases. Model B represents cell cycles 14 through 16, which are more complex and include a G2 phase. The figure shows two circular models, labeled Model A and Model B, that represent the cell cycle of fruit flies after fertilization. Model A represents cell cycles 1 through 13, and it contains two phases. Model B represents cell cycles 14 through 16, and it contains three phases.
What of the following explains the advantage of a G2 phase during embryonic development?
A Cells can undergo the cell cycle more quickly with a G 2 phase.
B Cells can replicate more DNA with a G2 phase.
C Cells are checked for DNA damage before entering mitosis with a G2 phase.
D Cells are able to produce two new daughter cells with a G2 phase.
Answer:
C. Cells are checked for DNA damage before entering mitosis with a G2 phase.
Explanation:
G2 phase is very important phase of cell division in which cells are checked for DNA damage before entering mitosis with a G2 phase as well as correct duplication of the DNA is also verified and cell proteins that are necessary for cell division are also produced. This phase comes after S stage in which replication of DNA occurs so this G2 phase check the damages before starting of mitosis.

What are the qualities of greenhouse gas? Select the two correct answers.
A. transparent to infrared radiation
B. three or more atoms in a molecule
C. produced by human activity
D. absorbs and re-emits infrared radiation
E. composed of single atoms, not molecules
I agree with the user's answer above ^. I think both choices suit the qualities of a greenhouse gases. So, yes 'absorbs and re-emits infrared radiation' and 'transparent to infrared radiation' are correct.
Infrared radiation is emitted by greenhouse gases. Therefore, option"A" is correct.
What are greenhouse gases?A gas that can absorb infrared light is referred to as a greenhouse gas. Only molecules with three or more atoms have the capacity to absorb infrared light. Homonuclear diatomic molecules like N2 and O2 don't absorb or emit infrared light because their dipole moments don't alter much.
The quantities of greenhouse gases are influenced by numerous factors. Fossil fuels release CO2 . Since the Industrial Revolution, human activities, particularly the burning of fossil fuels, have led to persistent increases in the atmospheric concentrations of different greenhouse gases, including carbon dioxide, methane, ozone, and chlorofluorocarbons (CFCs).

In the oldest fossils found in Bitter Springs (Cyanobacteria), why can we only find the remains of single celled organisms
Answer:
Due to presence at early days of the planet.
Explanation:
We only find the remains of single celled organisms in the oldest fossils because the single celled organisms are the organisms that were present in the early days of this planet. These single celled microbes were present about 3.7 billion years ago while on the other hand, the oldest rocks are only a little older i. e. 3.8 billion years so these single celled organisms are considered as oldest fossils on this planet.

A light bulb has a resistance of 4 ohms and a current of 2 A. What is the voltage across the bulb?
volts
Answer:
8 V
Explanation:
V= IR
V = 4×2
V= 8 V
The answer is the ohms × current
Voltage is an electrical difference of potential across the circuit. The voltage of the bulb is 8V with a current of 2 A and a resistance of 4 ohms.
What is ohms law?Ohms law gives the relation between the current (I) in Amperes, voltage (V) in volts, and resistance (R) in ohms. The formula to calculate voltage is given as,
[tex]\rm V = I \times R[/tex]
Given,
Current (I) = 2 Ampere
Resistance (R) = 4 ohms
Substituting values in the equation to calculate voltage as:
[tex]\begin{aligned} \rm V &= \rm I \times R\\\\&= 2 \times 4 \\\\&= 8\end{aligned}[/tex]
Therefore, 8 V is the voltage developed across the bulb with 4-ohm resistance.

Answer:
Producers make food and energy for themselves, and don't have to waste any energy hunting or scavenging for food. They also reproduce more effortlessly than consumers, and their genetic diversity is also a factor that keeps them abundant and numerous.
how does the surface area to volume ratio affect the rate of diffusion
Explanation:
As the ratio gets smaller, it takes longer for items to diffuse.
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.
When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.
this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.
