Which of the following statements about eukaryotic RNA is true?
O -A small cap of extra nucleotides is added to both ends of the RNA.
O -The modified RNA molecule is transported into the nucleus.
-Exons are spliced together.
-Introns are not transcribed from DNA to RNA.
Answer:
A small cap of extra nucleotides is added to both ends of the RNA
Hope you like it
Thank you ❤️
The statement 'exons are spliced together' is TRUE. The exons are the coding regions of genes.
RNA splicing is a eukaryotic mechanism by which non-coding sequences of genes called 'introns' are removed from the precursor messenger RNA (pre-mRNA), whereas protein-coding sequences called 'exons' are spliced together.These gene coding sequences (exons) are spliced together by a macromolecular complex known as the spliceosome.In consequence, a pre-mRNA is converted into a mature mRNA, which is subsequently used for protein synthesis.In conclusion, the statement 'exons are spliced together' is TRUE.

A hypothesis is a plausible explanation for a particular fact, observation, or process. Write a hypothesis about how the various concentrations of acid will affect the amount of limestone that is dissolved from each jar.
The hypothesis will state as follows: IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase.
WHAT IS A HYPOTHESIS?
A hypothesis is a crucial part of the scientific method. It is a testable explanation of an observation or a proposed answer to a scientific question. A hypothesis, which must be testable via experimentation, can either be accepted or rejected depending on the outcome of the experiment. A hypothesis is an IF, THEN statement that must include the independent and dependent variables of the experiment i.e. it must show how the dependent variable (effect) is affected by the independent variable (cause).In this case regarding the dissolution of limestone with respect to different concentrations of acid, a possible hypothesis will state as follows:
"IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase".

A. where light energy is not available.
B. in oxygen-rich environments.
C. when water has a pH of 7.
Answer: the answer would be a
Explanation: because I had the same question too on acellus and got a right
Photosynthesis makes use of light energy while chemosynthesis is the main source of energy capture where light energy is not available.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

When glycogen is formed from monosaccharides, it occurs by a process called hydrolysis.
True
False
Answer:
yes its true. it occurs by a process called hydrolysis
The formation of glycogen from monosaccharides happens through the process of dehydration. So the statement is false.
What is the process of glycogen formation?
The process of formation of glycogen is called glycogenesis. Glycogen is the storage form of glucose, a primary carbohydrate in the liver and the muscle cells of animals
The process of Glycogenesis happens when the levels of glucose in the blood are high enough to allow the excess glucose to be stored.
The process of glycogenesis is stimulated by the insulin hormone. It helps the muscle cells to uptake glucose into themselves. Insulin is not required for the transport of glucose into the liver cells.
However, insulin has very important effects on the metabolism of glucose inside the liver cells. Insulates stimulates the process of glycogenesis and inhibit the process of glycogenolysis, which is the breakdown of glycogen into glucose.
Therefore the statement is false.

Most chemical reactions within cells do not occur spontaneously. Instead, they need a catalyst to get them started. Why do you think this is so?
Answer:
A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions. By bringing the reactants closer together, chemical bonds may be weakened and reactions will proceed faster than without the catalyst.

How long does it take for mammals to evolve into a distinctly new species? What changes occur over
this time?
Answer:
i hope this helps <3
Explanation:
A new study by Matt Davis at Aarhus University throws these losses into stark relief. He estimated how long it would take for mammals to evolve enough new species to replace the ones that we have eradicated. And his most realistic answer is somewhere from 3 million to 7 million years.
The time that would be taken for mammals to evolve into a distinctly new species is 3 million to 7 million. The changes that will occur will be mental and physical changes.
What is evolution?Evolution is a process of changing human characters or other animal characteristics over time. Evolution happens with time, and it is a natural process.
Species is a term that refers to different animals and plants living in the environment. Organisms of the same species can reproduce with each other. Other species are different from the one species.
Evolution in every species occurs with time and environmental conditions for better survival in the environment.
Thus, it would take mammals between 3 million and 7 million years to evolve into a wholly new species. The alterations that take place will affect both the mind and the body.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement best describes an environmental consequence of this process?
A. Chemicals added to the liquid can contaminate groundwater.
B. Wastewater is contaminated with oil and becomes sludge in landfills.
C. Water vapor is released into the air, which is considered a greenhouse gas.
D. Heavy metals are released into surrounding soil, poisoning local vegetation.
Answer:
Option A, Chemicals added to the liquid can contaminate groundwater, this statement best describes an environmental consequence of this process.
Explanation:
Fracking is a process of digging fossil energy sources, which need a lot of water and uses local water resources. It is drawn with high-pressure water, sand and elements, creating high pressure to block the porous rock and discharge gas. The spill itself stops energy from the drilling position, and may even make earthquakes, mainly due to the pumping of overflowing wastewater into porous rock types such as limestone. The most significant result of water distortion is on groundwater.To learn more about fracking, refer:
