Answer:
DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.
DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.
DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.
Explanation:
DNA ligase seals the fragment, DNA polymerase adds a new nucleotide, DNA gyrase unwinds the DNA, and helicase makes a dent in double helix.
What is DNA replication?DNA replication is the physiological method that generates two identical replicas of DNA from a single original DNA molecule in molecular biology.
DNA replication takes place in all living organisms and is the most important component of biological inheritance.
Helicase, primase, DNA polymerase, and ligase are the four main enzymes that aid in DNA replication.
Many proteins and enzymes play a role in DNA replication, including: Topoisomerase: This enzyme relaxes the super-coiled nature of DNA. Helicase: Helicase is a protein that separates the two strands of DNA at the replication fork.
The fragment is sealed by DNA ligase, a new nucleotide is added by DNA polymerase, the DNA is unwound by DNA gyrase, and a dent in the double helix is made by helicase.
Thus, this can be the match for the given scenario.

Which two structures produce energy that cells can
use?
O A and B
OB and C
O Cand D
O D and A
Answer:
According to the plant cell scheme, the two structures that produce energy that cells can use are D, which corresponds to mitochondria, and A, which is a chloroplast, so the answer is D and A (fourth option).
Explanation:
In the plant cell —unlike the animal cell— there are organelles called chloroplasts, responsible for converting light energy from the sun into chemical energy. In addition, there are mitochondria, which also provide useful energy to the cell.
In the chloroplast, photosynthesis takes place, a process that during the light phase produces ATP and NADPH⁺ from solar energy. In the mitochondria, energy in the form of ATP is obtained from glucose, due to oxidative phosphorylation and the electron transport chain.The organelles indicated in the diagram are mitochondria (A) and chloroplast (D), both responsible for producing energy for the plant cell.
Answer: D and A

how does the cytoskeleton help maintain cell shape?
Answer:
Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest. ... Microfilaments also provide some rigidity and shape to the cell. They can depolymerize (disassemble) and reform quickly, thus enabling a cell to change its shape and move.

Which phase consistently has the least number of cell in that phase?
Answer:
Cytokinesis had the least number of cells in that phase.
Specific proteins produced in a cell are directly related to the A. Number of mitochondria in the cell. B. Sequence of sugars and phosphates in the cell. C. Type of ribosomes in the cell. D. Sequence of nucleotides in the DNA of the cell.
Answer:
D. Sequence of nucleotides in the DNA of the cell.
Explanation:
Proteins are a type of biomolecules in living systems responsible for many phenotypic characteristics in organisms. Proteins are synthesized by a process called gene expression, which encompasses transcription and translation.
Using the central dogma of biology to trace, DNA (genes) contains information that encodes the production of proteins in the body. Therefore, the sequence of nucleotide bases in the DNA of a cell determines the sequence of mRNA that will be produced during transcription and ultimately, determines the specific type of proteins (amino acid chain) that will be produced in a cell during translation.

Explanation:
Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds.
Calcium, which is a metal, donates 2 electrons to chlorine.
The individual calcium atoms become ions with a negative 2 charge.
The bond between calcium and chlorine makes the atoms stable.
Calcium and chlorine attract each other.
Which best describes Shameeka’s error?
Calcium is a metal, so it donates protons, not electrons.
The individual calcium atom has a positive, not negative, 2 charge.
The bond formed makes the atoms unstable, not stable.
Calcium and chlorine repel, not attract, each other.
Answer:
The individual calcium atom has a positive, not negative, 2 charge.
Explanation:
The error in her study is in the second line of her note which suggests that the individual calcium atoms becomes ions with a negative 2 charge.
When atom loses electrons, it has a net positive charge on it. Not a negative charge. This is because the number of protons is now more than electrons. Therefore, a net charge on the calcium atom will be a positive one. This is her mistake.Answer:
B) The individual calcium atom has a positive, not negative, 2 charge.

What scientific theories?Scientific theories are the theories that are given by scientific facts and information. These theories are based on observation of natural things and places.
There is the transfer of energy in the natural world. Every organism and plant is connected with each other in the form of a transfer of energy. This is called a food chain.
In the food chain, the organism is divided into different levels. These levels are based on their food. They are autotrophs, heterotrophs, and decomposers. Autotrophs have the largest amount of energy.
Thus, the correct option is C) It involves a transfer of energy.

many
B. Robins and sparrows have different types of bases.
C. Robins and sparrows have different arrangements of the bases.
D. Robins and sparrows have the same arrangement of the bases.
Answer: the answer is C —> AP.EX
Explanation:
The nucleotide bases are the nitrogenous rings that form the backbone of the nucleic acid. Robins and sparrows have the same bases with different arrangements. Thus, option C is correct.
What are nucleotide bases?The nucleotide bases or the nucleobases are the fundamental units that together with the sugar molecule and phosphate make the structure of the DNA or RNA.
There is a total of five nucleotide bases divided into purines and pyrimidines based on their ring structures. The purine consists of adenine and guanine, pyrimidine of cytosine, uracil, and thymine.
The bases are universal in organism containing the DNA or RNA but only differs in their arrangements that result in the development of the various traits and characteristics of the organism.
Therefore, in option C. the bases are arranged differently in species.
