What happens to an organisms energy storage molecules when it reproduces
An organism's energy storage molecules decrease when it reproduces.
How does energy decrease?As a transfer molecule, ATP, between exergonic and endogenic reactions, energy is quickly depleted.
When cells divide during mitosis or meiosis, ATP and NADPH are used to power the processes.
As mitochondria are randomly distributed, their ATP generation continues because ATP is not stored but is constantly used.
The hydrolysis of ATP results in the formation of ADP, inorganic phosphate ion, and the release of free energy.
To carry out life processes, ATP is constantly broken down into ADP, and ADP, like a rechargeable battery, is constantly regenerated into ATP through the reattachment of a third phosphate group.
Thus, we can conclude that energy decreases when organisms reproduce.

During dna replication the wrong nucleotide was inserted in the DNA sequence. Which of the following terms describes the situation? Mutation, translation, regeneration, or transcription.
The situation in which the wrong nucleotide was inserted during DNA replication is referred to as a mutation.
DNA replication is the process by which DNA makes an identical copy of itself. This is critical for cell division during growth or repair of damaged tissues. DNA replication is a highly regulated process that occurs in three stages. Initiation, elongation, and termination are the three stages. The replication of DNA occurs in the nucleus of eukaryotic cells, and it is carried out by several enzymes in a semi-conservative manner.
During DNA replication, the two strands of the double helix unwind and separate. Each single strand then serves as a template for the formation of a new complementary strand. DNA polymerase is the primary enzyme involved in DNA replication. The addition of new nucleotides to the growing strand in a complementary manner occurs in the presence of DNA polymerase.
DNA Replication and Mutation During DNA replication, mistakes may occur. These errors, which can result from damage to the DNA molecule or mistakes made during DNA synthesis, are referred to as mutations. When a mistake is made during DNA replication, the incorrect nucleotide is inserted into the growing DNA strand. This can cause a mutation in the DNA sequence, which can have a wide range of effects, from none at all to severe genetic disorders.
The wrong nucleotide's insertion into the DNA sequence causes a mutation. DNA replication errors can result in a variety of mutations, including base pair substitutions, deletions, and insertions. These mutations can have a range of effects, from none at all to severe genetic disorders, depending on their location and severity.

What type of forensic technique should be used? Police discovered a badly damaged corpse the body was damaged beyond recognition the police expert however can use DNA _____ to identify the victim?
Answer:
DNA profiling or DNA fingerprinting
Explanation:
DNA profiling is also known as DNA fingerprinting which is widely used in to determine an individual's DNA characteristics.
DNA profiling is widely used in forensic technique in victim or criminal investigations, where DNA is collected that can be hair, blood, body tissue sample or other. The sample is then compared with other suspect's sample which are expected to to be involved to determine whether there is a genetic match and that will help to identify the victim or criminal.
DNA profiling is used to match genetic formation between people which will help to identify parentage testing as genes inherited in the family is almost same and the the victim body will be identified.
Hence, the correct answer is DNA profiling.
Answer:
DNA fingerprinting

Answer:

Explanation:i just did it
The following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option (B), as the beginning of a gene is the promoter.
What is the significance of the transcription initiation?Transcription initiation has many implications, such as the fact that prokaryotic initiation is different from eukaryotic initiation, where the RNA polymerase first binds at the promoter site of the gene, where it starts moving towards the gene, and then after reaching the termination site, the transcription stops. In this process, the final product is mRNA from DNA.
Hence, the following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option, as the beginning of a gene is the promoter.

What is DNA?
DNA has been known as the molecule that contains the genetic information that is necessary to generate proteins. This is due to the sequence of the nucleotides, which are the monomers of DNA. Each nucleotide has been contained a different base Adenine (A), Timine (T), Guanine (G), Cytosine (C).
When the cell has needs to synthesize the proteins, DNA has not used directly but the transcribed into RNA. This RNA has been directed to the ribosomes, organelles where the protein synthesis has been taken place, and according to the sequence of RNA which is complementary to DNA, the different amino acids has been coded. During translation, aminoacids are joined together to form proteins.
Therefore, All cells contain the same genetic information. Stem cells are the only cells that do not have an X or Y chromosome and can therefore go into either a male or female. Thus, option C is correct.

Base your answers to question 8 on the information below and on your
knowledge of biology. Evolution leads to changes in how frequently
certain traits appear in a population. 8) Describe how the process of
natural selection can result in an increase in frequencies of certain traits
found in a population *
Answer:
Natural selection refers the effect of selection pressure on the frequency of allele in the population.
Generally,natural selection increases the chances that certain allele will survive for long period of time, and therefore the chances of successive reproduction. Therefore organisms with these alleles with higher chances of reproduction have high selective advantages, and therefore better adapted to withstand the selective pressure and therefore undergo directional selection within the organisms in the population.
Consequently, they are better reproduced, and thus well populated.The r frequency of their traits is well expressed from generation to generation, and therefore naturally selected, and evolve over long period.
