Answer:
it would block the S-phase entry and cell growth
Explanation:
The Rb protein is known to be a major G1 checkpoint. Rb is also known to be a tumor suppressor since this protein limits cell proliferation by preventing entry into the S-phase entry and cell growth. When the cell is ready to enter the division phase, Rb is phosphorylated and thus inactivated. In HL-60 cells, it has been shown that the levels of phosphorylated Rb protein increase with progression from G1 to S and to G2/M. This protein acts as a negative regulator that blocks the activity of the E2F transcription factor.
What happens to groundwater when the rate of infiltration is less than the rate of water being pumped out of the ground? a. The water table is unchanged. b. The water table increases. c. The water table lowers. d. The water table is unaffected by infiltration.
Answer:
the answer is The water table lowers.
When the rate of infiltration is less than the rate of water being pumped out of the ground, the water table lowers. Thus, the correct option for this question is C.
What is a Water table?A water table may be defined as a boundary that lies below the ground and between the soil surface and the area where groundwater saturates spaces between sediments and cracks in the rock. The water that percolates down to the earth constitutes the water table.
According to the context of this question, if the rate of infiltration is less that means the percolated water is significantly less as compared to the water that is taken or being pumped out of the ground. In a more simple sense, water collected in the ground is less than the water taken from the ground. Due to this, the water table declines.
Therefore, when the rate of infiltration is less than the rate of water being pumped out of the ground, the water table lowers. Thus, the correct option for this question is C.

What is the material that allows plants to capture energy from the sun? How many different types of this material are there? (site 1)
Answer: The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. This is the process called Photosynthesis, by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel.
Explanation:
During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food). The photosynthesis process occurs in all plants and algae, as well as in some bacteria species.

If an object with 80 j of gravitational potential energy is raised twice as high, what would be its new gravitational potential energy?
a. 100 j
b. 160 j
c. Can't be calculated without
knowing its weight.
The gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy. And like this.
So, the answer is b. 160J

GIVING BRAINLIEST TO THE PERSON WHO HELPS ME!
Answer: The history of science is also a history of people resisting new discoveries that conflict with conventional wisdom.
Explanation: When Galileo promoted Copernicus’ theory that the Earth revolves around the sun – counter to church doctrine about the Earth being the center of the universe – he wound up condemned by the Roman Inquisition in 1633. Charles Darwin’s theory of evolution – that new species develop as a result of natural selection on inherited traits – ran into opposition because it contradicted long-held scientific, political and religious beliefs. Alfred Wegener’s 1912 proposal that Earth’s continents move relative to each other – the theory of continental drift – was rejected for decades, in part because scientists held fast to the traditional theories they’d spent careers developing.

List and describe the roles of the three different types of RNA involved in transcription and translation.
mRNA(messanger RNA)-results from transcription and contains the codons for protein synthesis .mRNA is synthesized by an enzyme called RNA-polymerase. It plays an important role in translation because it contains the codons that pair with anticodons from tRNA
t-RNA(transffer RNA)-carries the amino acids to the protein synthesis site(ribosome) and contains the anticodon that pairs with the codon from mRNA during translation
r-RNA(ribosomal RNA)- keeps the two ribosomal units together for the translation to take place
The three different types of RNA that are involved are:
mRNA(messenger)tRNA(transfer)rRNA(ribosomal)RNA'sThree major types of RNA are mRNA, or messenger RNA,which serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA,which serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled.

How is the respiratory and circulatory system of amphibians?Amphibians have three structures for breathing:
The lungsThe mucous membranes of the pharynx and mouthand The skin.The lungs are made up of two bags with no internal division. When still in the larval stage, they breathe through gills.
How does the circulatory system of amphibians work?Amphibians have a dual circulation, meaning the blood passes through the heart twice to complete the cycle. The blood reaches the heart, travels towards the lungs, returns to the heart and only then is carried to the body.
Whit this information, we can conclude that In the circulatory system there is the distribution of oxygen to the body and in the respiratory system the gas exchange.

Bacteriophage and E.coli are alike in the sense that they both lack membrane-bound organelles.
What are bacteriophage?Viruses that infect bacteria are called bacteriophage. The words bacteriophage mean "bacteria eater". Bacteriophages take over the machinery of host cells to produce copies of themselves and then destroy the host cell in the process.
Bacteriophages are composed of a supercoiled nucleic acid which is surrounded by a protein capsid.
A bacteriophage adheres to the surface the susceptible bacteria and injects its genetic material. This way they occupy the genetic machinery of the host and produce several copies of their own nucleic acid and also the protein capsid to surround it.
The result is the lysis of bacterial cell and release of thousands of bacteriophage viruses which are capable of infecting more bacteria in the same manner.
Bacteriophage are acellular structures lacking any membrane bound cell organelles. E.coli is a kind of prokaryotic bacteria which also lack membrane bound organelles.
Therefore, the correct option is D.

Explain how it is possible for nutrients to be transported to the cells of a flatworm with no circulatory system.
Answer:
Flatworms are beings that do not have a heart, veins, arteries, capillaries, hemolymph, or some type of circulatory fluid. Their circulation occurs between cells or intercellularly and they are responsible for transporting substances by diffusion from cell to cell.
Explanation:
Flatworms are considered multicellular eukaryotic organisms. This implies that in their cells they have a cellular nucleus, in which the DNA is contained, structuring the chromosomes. Likewise, they are made up of several types of cells, each one specialized in a specific function. They lack a structured circulatory system as such. Because of this they do not have specialized structures such as a heart or blood vessels, however, the circulation of certain substances is established between their cells. This is done thanks to the diffusion process. Substances pass from one cell to another through this process.This does not apply to all flatworms, since in some species of bog and digenae there is a certain organization and some very small conducting vessels known as the endolymphatic system, the which forms a kind of plexus in the parenchyma.It should also be noted that some species do not even have a digestive system, being the digestive tract the one in charge of digestive functions and the distribution of the nutrients they receive.
