A. internal and external anatomical features of the organisms.
B. ancestors that the organisms share in common.
C. chemical processes that occur within the organisms.
D. all of these
Answer:
D
Explanation:
The relatedness of organisms can also be determined by examining internal and external anatomical features of the organisms, ancestors that the organisms share in common and chemical processes that occur within the organisms. Therefore, option (D) is correct.
What are anatomy characteristics?Human anatomy is characterized by reproduction, inheritance, cellular organization, growth and development, response to stimuli, evolutionary-adapted traits, and metabolism.
Anatomical characteristics that are shared by multiple organisms as a result of a common ancestor are known as homologous structures. Homologous structures, or homologies, are the tetrapod limbs.

Why do individuals with recessive
traits show up with less frequency
in populations?
A. There are more dominant alleles in most
populations.
B. Individuals must inherit two copies of a
recessive allele to show the trait.
C. Recessive traits greatly outnumber dominant
traits in most populations.
The individuals with recessive traits show up with less frequency in populations because the individuals must inherit two copies of a recessive allele to show the trait.
What is an allele?"They are the alternative forms of a gene."
What is a recessive trait?It is a trait that is expressed only when the both alleles in the genotype are recessive.The genotype should be homozygous recessive for the trait to appear.What is a dominant trait?A dominant trait is a trait that is expressed even when one parent contributes the dominant allele.It is expressed when the genotype is heterozygous dominant or homozygous dominant.To learn more about recessive, dominant, and populations here,

Which characteristic is true of sexual reproduction but not of asexual reproduction?
Answer:
sexual reproduction involves to organisms
Explanation:
what do you see inside the cell? three chromosomes three sister chromatids three homologous pairs of chromosomes three homologous pairs of chromatids
Answer:
three homologous pairs of chromosomes
Explanation:
Inside the cell we can see three homologous pairs of chromosomes as in humans there are 23 pair of homologous chromosomes and they are very similar in size and shape.
Three chromosomes are not possible to see because there are only two chromosomes and if anyone is having three chromosomes then the person is suffering from down syndrome having 47 chromosomes.
Three sister chromatids is also not possible because only two sister chromatids are found after DNA replication.
Three homologous pairs of chromatids is also not possible because chromatids are not found in pair and sister chromatids are called homologous chromosomes.
Hence, the correct answer is "three homologous pairs of chromosomes".

Transcribe and translate the following DNA strand into an RNA strand: TACCA
GTAGATT
Answer:
Explanation:Key points:
Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.
Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).
Transcription has three stages: initiation, elongation, and termination.
In eukaryotes, RNA molecules must be processed after transcription: they are spliced and have a 5' cap and poly-A tail put on their ends.
Transcription is controlled separately for each gene in your genome.
Introduction
Have you ever had to transcribe something? Maybe someone left a message on your voicemail, and you had to write it down on paper. Or maybe you took notes in class, then rewrote them neatly to help you review.
As these examples show, transcription is a process in which information is rewritten. Transcription is something we do in our everyday lives, and it's also something our cells must do, in a more specialized and narrowly defined way. In biology, transcription is the process of copying out the DNA sequence of a gene in the similar alphabet of RNA.
Overview of transcription
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.
In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.
Example:
Coding strand: 5'-ATGATCTCGTAA-3'
Template strand: 3'-TACTAGAGCATT-5'
RNA transcript: 5'-AUGAUCUCGUAA-3'
For a protein-coding gene, the RNA transcript contains the information needed to synthesize a polypeptide (protein or protein subunit) with a particular amino acid sequence. In this case:
RNA transcript (acting as messenger RNA): 5'-AUGAUCUCGUAA-3'
Polypeptide: Met-Ile-Ser-STOP
In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.
Example:
Coding strand: 5'-ATGATCTCGTAA-3' Template strand: 3'-TACTAGAGCATT-5' RNA transcript: 5'-AUGAUCUCGUAA-3'
For a protein-coding gene, the RNA transcript contains the information needed to synthesize a polypeptide (protein or protein subunit) with a particular amino acid sequence. In this case:
RNA transcript (acting as messenger RNA): 5'-AUGAUCUCGUAA-3' Polypeptide: Met-Ile-Ser-STOP
RNA polymerase
The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.
RNA polymerase synthesizes an RNA strand complementary to a template DNA strand. It synthesizes the RNA strand in the 5' to 3' direction, while reading the template DNA strand in the 3' to 5' direction. The template DNA strand and RNA strand are antiparallel.
RNA transcript: 5'-UGGUAGU...-3' (dots indicate where nucleotides are still being added at 3' end)
DNA template: 3'-ACCATCAGTC-5'
RNA polymerase synthesizes an RNA strand complementary to a template DNA strand. It synthesizes the RNA strand in the 5' to 3' direction, while reading the template DNA strand in the 3' to 5' direction. The template DNA strand and RNA strand are antiparallel.
RNA transcript: 5'-UGGUAGU...-3' (dots indicate where nucleotides are still being added at 3' end) DNA template: 3'-ACCATCAGTC-5'
Stages of transcription
Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria. You can learn more about the details of each stage (and about how eukaryotic transcription is different) in the stages of transcription article.
Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription.

what evidence and logical reasoning support the conclusion that anaerobic organisms evolved first, followed much later by aerobic organisms?
Answer: The atmosphere of the early Earth consists mainly of carbon dioxide and nitrogen, with little or no oxygen. In this case, the ancient prokaryotes are anaerobic, which evolved in the absence of oxygen. Eventually, when photosynthetic bacteria became common, they released oxygen and changed the Earth's atmosphere.

Answer:
Characteristics that have helped humans survive major changes in the environment are their brains and body. Human's social cooperation with tool making always increases.
Survival of the fittest explains the mechanism of natural selection. The ability to adapt to new changes has helped humans survive major changes in the environment.
What is adaptation?Adaptation is the ecological process that is the process of the adjustment of the structures, behaviors, and physiology of the organism to suit the altered environment.
It is the variation that increases the fitness of the organism so that it can survive and reproduce in a specific environment. It is a dynamic evolutionary method, that is essential for the sustainability of the organisms.
