which ventricles are divided by the septum pellucidum?
Answer:
The septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain.
Explanation:
The septum pellucidum separates the lateral ventricles. The lateral ventricles are divided into two halves by the septum pellucidum, a thin, vertical partition of tissue. It is formed of white matter and is situated in the frontal region of the brain.
The corpus callosum, a sizable bundle of nerve fibers that links the two hemispheres of the brain, is considered to have been influenced by the septum pellucidum.
The biggest ventricles in the brain are called the lateral ventricles. They are situated on each side of the brain, and cerebrospinal fluid is contained inside them (CSF). The CSF assists in removing waste from the brain and spinal cord in addition to cushioning the brain and spinal cord.

ribozymes are rna molecules that have enzymatic activity. this conflicts with the belief of early molecular biologists that
Ribozymes conflict with the belief of early molecular biologists that each enzyme is a polypeptide. A ribozyme is composed of RNA.
A ribozyme (ribonucleic acid enzyme) is an RNA molecule capable of speeding up a chemical reaction.
In consequence, ribozymes have catalytic activity.
For example, within the ribosome, the large subunit of ribosomal RNA acts as a ribozyme that links amino acids during the synthesis of polypeptide chains.
On the other hand, enzymes are specific proteins (composed of amino acids) that can speed up chemical reactions.

Scientists have observed a gradual increase in temperatures in locations all across Earth, an event often called . The increase in temperature is one aspect of , a long-term change in weather patterns.
Answer:
Climate or Global Warming
Dunno what you're asking exactly-
A long-term change in the typical weather patterns that have come to characterize local, regional, and global climates on Earth is referred to as climate change.The phrase is synonymous with a wide variety of observed outcomes that are a result of these changes
What is a long-term change in weather patterns?
Storms, heat waves, floods, and droughts are just a few of the disasters that are getting worse as a result of rising temperatures.Warmer temperatures produce an atmosphere that can hold onto, release, and gather more water. This alters weather patterns such that wet areas get wetter and dry ones get drier. The long-term pattern of the weather in a place is called the climate.Hour by hour, day by day, month by month, or even year by year, the weather might change.A region's climate is determined by its weather patterns, which are typically monitored for at least 30 years.The climates in different places of the world vary.When the weather is consistent for several days or weeks at a time, a weather pattern develops.Cold weather, wet and rainy weather, and hot and dry weather are a few typical weather patterns.Heat waves, flooding, and blizzards can occur as a result of persistent weather patterns. Climate Change Causes... Greenhouse Gases.... Reflectivity or Absorption of the Sun's Energy.... Changes in the Earth's Orbit and Rotation.... Variations in Solar Activity.... Changes in the Earth's Reflectivity.... Volcanic Activity. These phenomena cover changes like sea-level rise, ice mass loss in Greenland, Antarctica, the Arctic, and mountain glaciers around the world, changes in flower/plant blossoming, and extreme weather events, in addition to the higher temperature trends indicated by global warming. The average thickness of 30 well-studied glaciers has declined by more than 60 feet since 1980, indicating that glaciers are thinning. Due to climate changes, the ocean level is rising, glaciers are melting, CO2 levels in the atmosphere are rising, the forest and wildlife are disappearing, and water life is also being disrupted.In addition, it is predicted that many species of plants and animals would become extinct if this trend continues.To learn more about weather patterns refer

to which part of a dna molecule are nucleotides added?
Answer:
Nucleotides are exclusively added to the 3' end of the developing strand when DNA is produced in the 5'-to-3' orientation. The 5'-phosphate group of the new nucleotide attaches to the 3'-OH group of the final nucleotide of the developing strand.
At the 3' end of the deoxyribose sugar, an upcoming nucleotide is added. The existing nucleotide's 3'-OH end and the new nucleotide's 5' phosphate make a phosphodiester bond. In this way, new nucleotides are added.
How does DNA polymerize?
The DNA is made up of nucleotides. Each nucleotide of DNA is made up of a deoxyribose sugar, a phosphate group, and a nitrogenous base. Nitrogenous bases include adenine, guanine, cytosine, and thymine. The sugar of the DNA has a lack of oxygen at the 2' end. A glycosidic bond connects the sugar's 1' end to the nitrogen base.
The 5' end of sugar is attached to the phosphate group. The 3' end of sugar is attached to the 5' phosphate of the new upcoming nucleotide. A phosphodiester bond is formed during the addition of new nucleotides. Two phosphate groups of the new nucleotides are removed. Example: If ATP comes, then it will make AMP and attach to the DNA chain.
Hence, at the 3' -OH end of sugar of the existing nucleotides, a new one is added.

Answer:
active transport (moving particles against the concentration gradient)making proteinscell division (for growth and repair)transmission of nerve impulsesHope this helps!
ATP is the energy currency of the cell and it is required almost everywhere. 4 cellular activities that would require the energy of ATP will be cellular respiration, ion transport, muscle contraction, nerve impulse.
What is the role of ATP ?The role of ATP is providing energy where it gets hydrolysed into ADP along with the phosphate ion where the reaction provides energy and this reaction brings about energy in the activity.
The cellular activities are the activities that take place inside the cell and various activities that will link to them in order to perform various functions. DNA synthesis, biochemical reactions, cellular respiration, cellular activities all takes place with the help of ATP.
Therefore, ATP is required almost everywhere in both cellular respiration activities and cellular activities.

what physical feature of dna is affected by the pairing of purines with pyrimidines?
Answer:
Its width.
Explanation:
The size of pyrimidines and purine is different because each group has a different structure (1 or two rings). Therefore, the width of DNA is "constant".
If we would pair two pyrimidines or two purines, the width of DNA would be different in both cases.
