A model cell with damaged DNA was created to explain the importance of checkpoints in a cell cycle. The G2 checkpoint accidentally failed to work during experimentation. What do you think is the likely consequence of this failure?.
Answer: the consequenc of this failure is The cell continued to divide uncontrollably to create more damaged cells Which can lead to deadly diseases like cancer, breast cancer and many more
If the G2 checkpoint accidentally failed, then the cell will enter into division. The likely consequence of this failure is that the cell proliferates in an uncontrolled manner.
The cell cycle is controlled by checkpoints that regulate the progression through different phases of the cell cycle.
The G2 checkpoint acts to prevent the entry in mitosis of cells that have damages in its genetic material (DNA) in order to repair it.
When the cell undergoes failures in the G2 checkpoint control, the cell divides in an uncontrollable manner and thus generate groups of damaged cells (e.g., a tumor).

Why is air temperature above land warmer than the air temperature above water in the same location during the summer?
Answer:
Sea breezes happen during the hot, summer days due t the unequal heating rate of land and water
Explanation:
Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

Which statement describes how the models will be similar? *
Answer:
A
Explanation:
They will all be formed around carbon chains and rings
In all the four types of biomolecule models, all the biomolecules should have carbon chains and rings in their models. Thus, the correct option is A.
What are Biomolecules?Biomolecules are the basic and the main components of the food components that we eat. Biomolecules provides us energy in the form of ATP through cellular respiration and performs many vital role in the body of the organism.
The major classes of biomolecules are carbohydrates, fats, protein and nucleic acids. The common thing in all the four biomolecules is that they are formed of carbon chains and rings.
All the biomolecules are formed by carbon atoms, and other components like oxygen, hydrogen, nitrogenous bases, etc.

What type of weather is associated with High Pressure systems?
Question 4 options:
it is always different
snowy weather
clear sunny skies
cloudy stormy weather
Answer:
it's option C) clear sunny skies.
The type of weather associated with High pressure systems is : ( C ) clear sunny skies
High pressure systems have a greater amount of air pressure within their systems, when compared to its surroundings. Due to the presence of high air pressure within the system the air in the system is pushed into the surroundings.
Types of pressure systemsThere are two types of pressures systems and they are
High pressure system ; Possess more air pressure within the system Low pressure system ; Possess less air pressure within the systemAs the air leaves the high pressure system into the surroundings the system becomes clearer ( i.e clear sunny skies is evident in a high pressure system).
Hence we can conclude that the type of weather associated with high pressure systems is clear sunny skies

How does galaxy composition typically relate to the age of the stars in the galaxy? (1 point)
Star aging emits gas and dust, so galaxies with the youngest stars typically have the lowest proportions of dust and gas.
Star formation and the presence of young stars is common across galaxies, regardless of the proportions of dust and gas present.
Stars form from dust and gas, so galaxies with younger stars typically consist of higher proportions of dust and gas than other galaxies.
O Star formation consumes dust and gas, so galaxies where stars are oldest typically consist of higher proportions of dust and gas than other galaxies.
H
Galaxy composition typically relate to the age of the stars in the galaxy
through Stars being able to form from dust and gas, so galaxies with
younger stars typically consist of higher proportions of dust and gas than
other galaxies.
Components of a StarDustGasThe age of stars are usually determined through the amount of gas and dust
present in them. Stars burn gas to emit light and the younger ones have
more proportion of gas present than the older ones. The older ones have
less proportions due to more gas being burned over time.
The stated facts therefore makes option C the most appropriate.

Match the digestive organ on the left with its function.
Answer:
pancreas: secretes digestive enzymes into the small intestine
esophagus: the place where peristalsis takes place
small intestine: area of the digestive tract where most nuturients are absorbed
stomach: area of the digestive tract that follows the esophagus
large intestine: area of the digestive tract where mostly water is absorbed
Explanation:
peristalsis: so the food can move down towards your stomach, independently of gravity
pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes
small intestine: it is really really long -> more time to absorb nutrients
large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place

In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.
Answer:
prokaryotes
Explanation:
All cells translate using ribosomes. Prokaryotic DNA lacks a nucleus, therefore translation happens before transcription. Simultaneous transcription and translation takes place.
What is translation in prokaryotes?In all cells, translation takes place at ribosomes. Prokaryotes translate DNA before transcription is finished because their DNA is not bound by a nucleus. Both transcription and translation take place at once. When a start codon on mRNA attached to a small ribosomal subunit is recognized by an initiator tRNA anticodon, translation can start. A second tRNA is recruited as the big ribosomal subunit joins the tiny subunit.
This is not conceivable in eukaryotes because translation takes place in the cytoplasm outside of the nucleus, whilst transcription takes place in a membrane-bound nucleus.
