Answer: d. All the body cells arise from mitotic divisions of the same fertilized egg.
Explanation:
After conception occurs and an egg is fertilized, mitosis takes place as the egg begins to divide into other cells. This is how all the cells in the body are eventually formed regardless of how specialized their roles are.
As a result, every cell in the human body shares the same genes so any biological liquid or structure of the body would indicate the criminal because they would share the same gene as the rest of the cells in the criminal.
The Six Kingdoms: Plants, Animals, Protists, Fungi, Archaebacteria, Eubacteria. How are organisms placed into their kingdoms?
Answer:
Organisms are placed into their Kingdoms based on their type of cells, their ability to make food, and the number of cells in their bodies.
Explanation: Hope this helps :)
The kingdom is the taxonomical classification. The six kingdoms are divided and differentiated based on the cell type, cell shape, structure, and similarities.
What is the kingdom?The kingdom is the first level of the taxonomical classification that contains a large number of species and further classifies the organisms based on their similarities and differences. It includes plants, animals, protists, fungi, archaebacteria, and eubacteria.
The species are classified based on the cell structure and their shape that makes them different from each other like the prokaryotes and the eukaryotes. Further, they are classified based on the cell number like single or multi-celled structures.
Then they are differentiated further based on the other characteristics like the cell organelles, cell function, and activities, mode of nutrition, reproduction, and the organization of the body.
Therefore, the kingdom classifies the organisms based on similarities and differences.

What is the relationship between the places where malaria is common and where the sickle cell allele is commonly found?
Answer:
At a global scale, the sickle cell gene is most commonly found in areas with historically high levels of malaria, adding geographical support to the hypothesis that the gene, while potentially deadly, avoids disappearing through natural selection by providing protection against malaria.Nov 2, 2010

Which statement best describes a function of the proteins embedded in the plasma membrane of cells? *
- They selectively allow certain particles into and out of the cell.
- They attract charges in the cell's environment to give the cell a net charge.
- They provide instructions for the processes in the cell.
-They store the energy required by the rest of the membrane to perform its functions.
Answer:
They selectively allow certain particles into and out of the cell
Explanation:
Proteins in the cell membrane allow some particles to enter and exit the cell. This type of passive transport is called facilitated diffusion.
Cells that are metabolically active and use a lot of energy: include red blood cells. include white adipose (fat storage) cells. are found in the dermal layer, just under the skin. are densely packed with numerous mitochondria. generally are not found in the human body.
Answer:
are densely packed with numerous mitochondria.
Explanation:
Mitochondria are considered as the energetic centers of the eukaryotic cells. These organelles (mitochondria) produce energy in the form of Adenosine Triphosphate (ATP) through the mechanism of cellular respiration, i.e., mitochondria are the organelles where aerobic phases of cellular respiration occur. In presence of oxygen, mitochondria convert chemical energy obtained from foods to ATP, which is the energy coin that cells use to carry out all their metabolic processes (e.g., reproduction, growth, development, etc). Thus, cells with high metabolic requirements need to have many mitochondria in order to produce more ATP.
For humans, linoleic acid is one of the essential fatty acids we must consume. It is plentiful in vegetable oils, and we use it to form compounds involved in immune responses. When it is decomposed through a process called b-oxidation, it produces effectively 27 NADH, 9 FADH2 and 9 ATP in the Krebs cycle, along with 9 FADH2 and 9 NADH as part of the decomposition.
Required:
How many ATP should this produce?
Answer:
18 ATP.
Explanation:
Total 18 ATP are produced because 9 FADH2 are converted into 9 ATP molecules and the earlier 9 ATP molecules are already present in the first b-oxidation process. The first Krebs cycle produces 27 NADH, 9 FADH2 and 9 ATP while on the other hand, the second Krebs cycle produces 9 ATP molecules from 9 FADH2 so total it produces 18 ATP molecules.
How are karyotypes useful? Select two answers
They can help us identity genetic mutations
They can help us identity chromosomes mutations
They can help us identity the gender of an individual
Mutation is a natural process that changes a DNA sequence. Most DNA changes Faul in a large areas of the genome that sits between genes, and usually they have no effect. When variation occur within jeans, there is more often a consequence, but even then mutations only really cause death or disease. Mutations also generates new variations that can give an individual A survival advantage.
Answer:
The correct answer is -
1) point mutation
2) deletion
3) inversion
4) frameshift mutation.
Explanation:
Point mutation or substitution mutation is a genetic mutation that takes place when there is a change in a single base nucleotide, it can be replaced with other nucleotides from a DNA or RNA sequence of an organism's genome.
Deletion is a genetic mutation that occurs when there is a loss of a segment of a chromosome. If the particular segment is responsible for an important protein or gene the offspring have to be with one copy only therefore, it is considered a bad mutation.
When there is a reversal of the segment of a chromosome occurs a change takes place in genetic material which is known as the inversion type of genetic mutation.
If any of the above mutations take place including deletion, inversion, replacement or insertion in one or more nucleotides to make a change in the amino acid sequence from the site of mutation forward is frameshift mutation.
Why don’t animals need cells with walls
Answer:
Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones .
Explanation:
true or false the typical X shaped chromosomes is the result of DNA replication
Answer:
True
Explanation:
Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.
When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.
Aquifer is the process of seeping of water under the ground.
Answer:
The process of seeping of water into the ground is called infiltration. The groundwater thus gets recharged by this process. At places the groundwater is stored between layers of hard rock below the water table. This is known as an aquifer.
Answer:
Explanation:
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater can be extracted using a water well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.
