Answers
Mutations are rare and can occur in body cells.
Mutations are changes in the DNA sequence of an organism.
They can occur in both body cells and reproductive cells, meaning they can be passed down from generation to generation.
Mutations can be beneficial, harmful, or have no effect on an organism's fitness.
While some mutations can lead to diseases, others can help an organism adapt to its environment or improve its chances of survival.
However, most mutations are rare and do not have a significant impact on the organism.
Therefore, it is not accurate to say that mutations are always harmful.
Germline mutations specifically occur in reproductive cells and can be passed down to offspring.

What was the climate like prior to the extinction ?
Answers
Answer:
The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

Over time, the mice develop local adaptations that result in divergence of the original species o After the dinosaurs went extinct, the mammals they coexisted with them see a significant increase in species
Answers
The example not of adaptive radiation is: (2) After a few plant species have gone extinct in an area, a surviving plant species spreads into this same area, and its population triples in size.
Adaptive radiation is the phenomenon of increase of the species having a common ancestor therefore developing into several different lineages. In the given question, the same extinct plant species spread into the area and increase in size, but no new species are observed and hence it is not an example of adaptive radiation.
Extinction is the phenomenon of disappearance of a certain species from the whole world. When the last living individual of any species, dies off, it is said to become extinct.

Photosynthesis and cellular respiration are two close related and complementary processes. Photosynthesis produces organic molecules and releases oxygen, which are used during cellular respiration to produce water, ATP, and CO₂.
What are photosynthesis and cellular respiration?
Photosynthesis is a process plant cells go through when absorbing sunlight.
During photosynthesis, light energy and inorganic compounds are used to produce organic compounds -glucose- and release oxygen.
It occurs in chloroplasts and involves two stages: light-dependent and light-independent reactions.
• During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions. It occurs in the thylakoid membrane in the electron transporter chain.
• The light-independent reaction occurs in the Calvin cycle in the stroma. During this stage, carbon from CO2 is fixated, and sugar molecules are synthesized
Cellular respiration is the process through which cells use organic compounds to produce energy.
Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
Aerobic Respiration1. Occurs in the presence of free oxygen.
2. Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
3. Respiration occurs in the mitochondria.
4. Takes place in two steps or stages: Krebs cycle and electron transporter chain.
5. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
Anaerobic Respiration1. Occurs in the absence of free oxygen
2. Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
3. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
4. Lactic fermentation produces lactic acid and 2 ATP
5. Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
6. The whole anaerobic process occurs outside the mitochondria.
Photosynthesis is complementary to cellular respiration.

The factors that affect the fluidity of the plasma membrane are as follows:
temperaturecholesterolthe kind of fatty acids in the phospholipids that form the cell membrane.An increase in the cholesterol concentration generally decreases membrane fluidity, which is why lipid rafts have a much higher concentration of cholesterol than the surrounding membrane. This means that decreasing cholesterol content would make the membrane more fluid.

Explanation:
Eukaryotic genes can be introduced into bacteria by recombinant DNA techniques. If the introduced gene encodes a protein that is also found in bacteria (for example, a universally used glycolysis enzyme) then, expression of the eukaryotic gene may produce a protein that functions in the bacterial cell. The mouse gene for a glycolysis enzyme is introduced into an E. coli cell that has a mutant gene for the bacterial version of the same enzyme. Even though the mouse enzyme should function in the bacterial cell and restore the cell's ability to perform glycolysis, it does not. Provide two possible reasons why this experiment does not work and propose a solution to overcome one of the problems you suggest.
Answers
Answer:
Introns are the non coding regions that are available in the eukaryotic genes, before being transcribed they get spliced out. Prokaryotic genes do not have introns and so the cells do not have intron splicing enzymes and hence cannot remove introns from the RNA. Hence if introns are present in the mouse gene, they will not be removed after it is transcribed in E.coli. If such RNA with introns is translated, it results in an altered protein with extra aminoacids or an incomplete protein.
1. The prokaryotic RNA polymerase does not recognize the eukaryotic promoter, so there is no transcription. A eukaryotic gene that will be introduced into bacteria for expression must be engineered to have a prokaryotic promoter.
2. There is no Shine–Dalgarno sequence in the eukaryotic gene promoter, so even if an mRNA is produced, the prokaryotic ribosome will not efficiently recognize the translational start site. If a prokaryotic promoter is used to express this gene, it should have the Shine–Dalgarno sequence within it.
