Peptide A: Ala 10%, Glu 5%, Ser 5%, Leu 10%, Arg 10%. His 5%, Ile 10%. Phe 5%,Tyr 5%, Lys 10%, Gly 10%, Pro 5%, and Trp 10%. Peptide B: Ala 5%. Val 5%, Gly 10%, Asp 5%, Leu 5%.

Peptide C: Ala 10%, Glu 10%, Gly 5%, Leu 5%, Asp 10%, Arg 5%, Met 5%, Cys 5%,Tyr 5%, Phe 5%, His 5%, Val 5%, Pro 5%, Thr 5%, Ser 5%, Asn 5%, and Gln 5%.
Answers
The order of the three peptides is Peptide C, Peptide A, Peptide B.
A cation-exchange column is a type of chromatography that separates molecules based on their net charge. At a neutral pH of 7.0, the charge of a peptide depends on the distribution of positively charged and negatively charged amino acids within its sequence.
The order of elution from a cation-exchange column can be predicted based on the net charge of each peptide. At neutral pH, positively charged amino acids like arginine, lysine, and histidine will have a positive charge, whereas negatively charged amino acids like aspartic acid and glutamic acid will have a negative charge.
Peptides with more positively charged amino acids will bind more strongly to the negatively charged cation-exchange polymer and will be eluted later.
Based on this information, we can predict the order of elution of the three peptides as follows:
Peptide C, which has the highest concentration of negatively charged amino acids, will be eluted first.
Peptide A, which has a balanced distribution of positively and negatively charged amino acids, will be eluted next.
Peptide B, which has the lowest concentration of negatively charged amino acids, will be eluted last.

Answers
The correct answer is d. they share an ancestor. When two animals have an identical sequence of amino acids in a protein, it suggests they share a common ancestor with a conserved genetic information.
When two animals have an identical sequence of amino acids in one of the proteins found in their cells, it indicates that they share a common ancestor. Proteins are encoded by genes, and the sequence of amino acids in a protein is determined by the DNA sequence of the corresponding gene. The DNA sequence is passed down from generation to generation through inheritance.
If two animals have the same sequence of amino acids in a specific protein, it suggests that the DNA sequence coding for that protein has been conserved over time, likely due to a shared ancestry. This conservation of the protein sequence indicates that the genetic information for producing that protein has been passed down from a common ancestor to both species.
On the other hand, options a, b, and c are not necessarily true based solely on the fact that two animals have an identical sequence of amino acids in a protein. The animals could have different dietary habits (option a), may have been exposed to different mutagenic substances (option b), and do not necessarily belong to the same genus (option c). Only the shared ancestry (option d) is directly indicated by the identical protein sequence.

F- Explain the global carbon-climate cycle during the Cretaceous period. (Write only one paragraph describing what happened during the Cretaceous geological period in order to have good source rocks.)
Answers
During the Cretaceous period, high temperatures and abundant vegetation resulted in increased \(CO_2\) levels, leading to the accumulation of organic matter and the formation of good source rocks for oil and gas.
During the Cretaceous period, spanning from approximately 145 to 66 million years ago, the global carbon-climate cycle played a crucial role in the development of favorable conditions for the formation of good source rocks. The period was characterized by high global temperatures and abundant vegetation, resulting in increased carbon dioxide \((CO_2)\) levels in the atmosphere.
The elevated \(CO_2\) levels fueled vigorous photosynthesis, leading to the accumulation of organic matter in marine and terrestrial ecosystems. As this organic matter was buried and subjected to heat and pressure over millions of years, it transformed into oil and gas, creating potential source rocks. The warm climate and prolific vegetation during the Cretaceous, along with the subsequent geological processes, contributed to the formation of the rich hydrocarbon reserves that are vital to our energy resources today.

Answers
slower; the base pair size of the band is larger than that of the tubulin band. The CAMV35S promoter is often used in genetic modification of plants, and its band size is larger than that of the tubulin gene. Therefore, it would move slower during gel electrophoresis.
Based on their size and charge, biomacromolecules (DNA, RNA, proteins, etc.) and their fragments can be separated and analysed using gel electrophoresis. It is used in clinical chemistry to separate proteins by charge or size (IEF agarose, effectively size independent) and in biochemistry and molecular biology to separate a mixed population of DNA and RNA fragments by length, estimate the size of DNA and RNA fragments, or separate proteins by charge.

Answers
Within eukaryotes, organelles perform specialized tasks like photosynthesis, energy production, and membrane synthesis.
The majority of them are membrane-bound structures that serve as the locations of particular biochemical reactions. Because it houses a cell's DNA, the nucleus is one of the most crucial eukaryotic organelles. Chloroplasts and mitochondria are two additional crucial organelles that are thought to have evolved from simple single-celled organisms and play significant roles in energy conversion. Because they transform energy from one form to another—from food nutrients to ATP—mitochondria in eukaryotic cells behave somewhat like batteries. Accordingly, cells with high metabolic demands can satisfy their higher energy requirements by containing more mitochondria. For instance, muscle cells from athletes have more mitochondria than muscle cells from sedentary individuals.

cells within the same organisms are capable of differentiating into specific cell types because they are able to select which genes they inherit from stem cells. true or false
Answers
False.
Cells within the same organism differentiate into specific cell types through a process called gene expression, not by selecting which genes they inherit from stem cells.
All cells in an organism contain the same set of genes, but not all genes are active or expressed in every cell. Differentiated cells express only the genes necessary for their specific functions, while other genes are turned off or silenced.
This regulation of gene expression is controlled by a variety of factors, including DNA methylation, histone modification, and transcription factors, which determine which genes are turned on or off in each cell type. Stem cells have the potential to differentiate into multiple cell types, but this is not because they selectively inherit specific genes.

Answers
Answer: extremely high up I think
Explanation: hope this helped
The option (D) is correct. Extremely high up accurately describes the mesosphere.
What do you mean by mesosphere?The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.
Moreover, the mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere.
Hence, it is the coldest place on Earth and has a temperature on the order of − 85°C (− 120°F). Just below the mesopause, the air is so cold that even the very scarce water vapor at this altitude can be sublimated into polar-mesospheric noctilucent clouds.

why does hereditary spherocytosis result in normocytic, normochromic anemia in the peripheral smear?
Answers
Hereditary spherocytosis results in normocytic, normochromic anemia in the peripheral smear because of the increased destruction of the red blood cells (RBCs) that are spherical rather than the normal biconcave shape.
Hereditary spherocytosis (HS) is an inherited disorder of the RBCs, which is caused by mutations in genes encoding proteins of the RBC membrane and cytoskeleton. The membrane and cytoskeleton protein deficiencies result in a decrease in the surface-to-volume ratio of the RBCs, leading to their sphere-shaped morphology. Additionally, this sphere-shaped morphology renders the cells more vulnerable to shear stress, decreasing their flexibility and making them less deformable than normal RBCs.
Consequently, HS is associated with splenomegaly, hemolytic anemia, and hyperbilirubinemia, which can lead to bilirubin gallstones and neonatal jaundice. In HS, the sphere-shaped RBCs are not as flexible as the normal biconcave-shaped RBCs. Thus, they become trapped in the smaller blood vessels of the spleen and destroyed, leading to hemolytic anemia. The removal of these sphere-shaped RBCs results in the formation of reticulocytosis, the premature release of immature RBCs, which leads to normocytic, normochromic anemia in the peripheral smear.
In conclusion, HS is an inherited disorder of the RBCs, caused by mutations in genes encoding proteins of the RBC membrane and cytoskeleton. The sphere-shaped RBCs are not as flexible as normal RBCs, and they become trapped in the smaller blood vessels of the spleen and destroyed, leading to hemolytic anemia.
