Guanine and adenine are purines found in DNA. View Available Hint(s)for Part A True False Submit Part B
Answers
The given statement "Guanine and adenine are purines found in DNA" is true because both Guanine and adenine are purines found in DNA.
Purines and pyrimidines are the nitrogen-containing bases that makeup DNA. There are two purine bases, adenine (A) and guanine (G), and three pyrimidine bases, cytosine (C), thymine (T), and uracil (U).
Purine bases, on the other hand, are made up of two carbon-nitrogen rings joined together. In DNA, Guanine is paired with cytosine, and adenine is paired with thymine. DNA is a double-stranded, twisted helix that encodes genetic information. Each strand of DNA consists of nucleotides that are held together by covalent bonds.

space in the back containing the spinal cord and is surrounded by the backbones is known as epidural space.
Epidural space is the fatty space between the bony framework of the spinal vertebral column and the thick dura mater which surrounds the spinal cord. It consists of adipose tissue and blood vessels.
The connective tissue that surrounds the brain and spinal cord is known as the meninges. The dura mater, a thick and compact tissue that is repeated to create the periosteum of the inner skull, is the outermost layer. The arachnoid, a network of loose connective tissue devoid of blood arteries, lies underneath the dura. The corpus callosum connects the two parts of the brain and transmits information between them.

Complete the following sentences to describe the stages of the cell cycle. Choices may be used more than once. Then, place the sentences in chronological order beginning with a freshly divided cell.
Answers
After one full cycle of cell division, there is a phage called interphase. It takes up the majority (more than 95%) of the time inside the cell division process and is the longest period of the cell.
How might cell division be explained?When a parental cell divides, two or even more daughter cells are created. This process is known as cell division. For a lot of creatures, it is a crucial biological process. In order to develop, replenish (repair), and reproduce, multicellular organisms adopt this method.
Cell division is known for what purpose?To create new cells, cells divide. One cell splits to create two, then these two cells divide again to create four, and so on. Because old cells divide to create new ones, this process is also known as "cell division" or "cell reproduction."

Describe 2 symbiotic relationships between animals and chemosynthesizers seen at hydrothermal vents.
Answers
The first type of symbiotic relationship between animals and chemosynthesizers at hydrothermal vents is commensalism. and The second type of symbiotic relationship is mutualism.
Commensalism is when one organism benefits from the relationship while the other is neither harmed nor helped by it. For example, shrimp may live around the vents and scavenge food from the bacteria, while the bacteria still benefit from the warmth and minerals of the vents.
Mutualism is when two organisms both benefit from the relationship. For example, some species of clams at hydrothermal vents have bacteria living inside their gill tissues that produce energy for the clams through chemosynthesis.

Answers
According to the question, if a plant fixes X amount of energy, the second trophic level will have access to 10% of X, or 0.1*X, and the third trophic level will have 10% of 0.1*X, or 0.01*X.
Approximately energy will be available to the third trophic level will be 0.01*X.
What phases of an ecosystem's energy flow are there?
The transmission of energy from one organism to another, starting with the autotrophs and rising up the food chain as animals are consumed by one another, is referred to as energy flow. Pyramids of food and energy are another approach to show this kind of chain or just to show the trophic levels.

A scientist makes primers specific to a particular str fragment in elephants. These primers are then used to amplify the str fragment from 10 different elephants. Would you expect the fragment to be the same size in all the elephants? explain your answer.
Answers
The STR fragments will have different sizes for different animals.
STR means Short Tandem Repeats. STR forms the genome's microsatellite region. STR or microsatellite is that region of the genome where, about two to seven base pairs of the DNA, are repeated multiple times. Such sequences can have a few hundred repeats.
While replicating these micro-satellite regions, the accuracy of the DNA polymerase in proofreading the sequence of the newly synthesized strand, decreases, due to the multiple repeats. As a result of this, the DNA polymerase either adds more or adds less of such repeated sequences as compared to the parental DNA sequence.
This results in the generation of polymorphism in the repeat regions. Due to the difference in the size of the STR in different individuals, the size of the fragment amplified through PCR will vary for different elephants.

errors by dna polymerase that incorporate the wrong nucleotide into replicating dna can be repaired quickly by which two mechanisms?
Answers
The two techniques for promptly correcting DNA polymerase errors that introduce the incorrect nucleotide into replicating DNA are mismatch repair by specialised enzymes and proofreading by the polymerase itself.
DNA polymerase recognises and removes erroneous nucleotides that have been integrated into the freshly synthesised DNA strand during DNA replication, effectively editing its own work. This procedure helps to assure high fidelity replication since it takes place in real-time as DNA polymerase proceeds along the template strand. However, mistakes might still happen even after proofreading. A backup mechanism called mismatch repair finds and fixes mistakes that are missed by proofreading. Specialised enzymes use the template strand as a guide to identify, eliminate, and replace the erroneous nucleotide with the correct one. Following DNA replication, a repair process ensures that mistakes are fixed before they lead to irreversible mutations.
