What is photosynthesis?Photosynthesis is one of the many chemical reactions that occur in living organisms.
Photosynthesis is the process by which living organisms known as plants use the energy of sunlight to convert carbon dioxide and water into chemical energy stored in foods.
These chemical reactions are known as metabolic reactions and are essential for the growth and development of the living organism.
Considering the given descriptions of metabolic reactions:
Photosynthesis is the process some organisms are able to use by which they convert light energy to chemical energy. It is the main method by which photosynthesizing organisms use for carbon dioxide fixation to produce food nutrients.
The green pigment that absorbs light and provides energy for photosynthesis is chlorophyll.
Pigments are substances that absorb some wavelengths of light and reflect others, giving something its color.
Chlorophyll is found within chloroplasts. Thylakoids are disc-shaped sacs in chloroplasts where photosynthesis takes place.
Through the process of respiration, cells produce energy from carbohydrates. In living organisms such as man, the citric acid cycle is a set of chemical reactions that break down pyruvate, producing electron carriers for an electron transport chain that powers ATP production.
Adenosine triphosphate, ATP, is a substance that stores and releases energy for most cell processes.
The electron transport chain refers to a series of molecules in the inner membranes of chloroplasts and mitochondria down which excited electrons pass, releasing energy for ATP production.
ATP production can occur under aerobic or anaerobic conditions.
Aerobic reactions are processes that require oxygen while anaerobic reactions do not require oxygen.
The process by which NAD is recycled under anaerobic conditions in order to continue the breakdown of carbohydrates to supply energy for producing ATP is called fermentation.

A humpback whale is classified as a mammal while a basking shark is a fish. Which taxonomy classification are the same for a humpback whale and a basking shark
Answer:
A. Domain, kingdom, phylum only
Explanation:
The domain is Bacteria, Archaea, and Eukarya which every living thing falls under, the kingdom is every animal (now that's excluding plants and bacteria), and the phylum is a primary category in biological taxonomy especially of animals that ranks above the class and below the kingdom.
The taxonomic classification that is the same for a humpback whale and a basking shark is Phylum.
A chordate refers to an animal (Kingdom Animalia) of the phylum Chordata.This phylum includes all vertebrates as well as two other subphyla tunicates and cephalochordates.Chordates are characterized to have a notochord, pharyngeal slits (embryo development), nerve cord, and a tail.In conclusion, the taxonomic classification that is the same for a humpback whale and a basking shark is Phylum.

The space surrounding the nucleus of an atom contains what particles?
Answer:
An atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outer region of the atom, which holds its electrons in orbit around the nucleus.
The space surrounding the nucleus of an atom contains electrons.
Negatively charged electrons are subatomic particles that orbit the nucleus of an atom at a particular energy level, or electron shell. Compared to the other particles inside the nucleus, protons and neutrons, they are very light and small. Despite having much less mass than protons and neutrons, electrons play an important role in determining the general behavior and characteristics of atoms.
The configuration of electrons in an atom's electron shell determines its chemical structure and reactivity. Depending on how far they are from the nucleus, electrons reside in different energy levels, with the maximum number of electrons allowed in each level.

In the late 1800s, a biologist studying animal embryos coined the phrase "ontogeny recapitulates phylogeny," meaning that the physical development of an animal embryo (ontogeny) seemed to retrace the changing form of the species during its evolutionary history (phylogeny).
Why would embryonic development retrace evolutionary steps?
Answer:
Embryo provides information about their ancestors.
Explanation:
Embryonic development retrace evolutionary steps because embryo provides evidence for evolution as embryo formation in widely-divergent groups of organisms are conserved. This embryo provides information that leads to their ancestors from which they evolve so we can say that embryonic development provides evidence for evolution of an organism.

Answer:
1. The difference between the normal hemoglobin protein DNA sequence and the sickle cell hemoglobin DNA sequence is a base to base shift, in this case adenine (GAG) to thymine (GTG).
2. The difference affects the amino acid sequence of the protein by replacing glutamic acid (Glu) with valine (Val).
Explanation:
In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the amino acid sequence of globine β, incorporating valine instead of glutamic acid. This represents a molecular mutation - point mutation - by subtitution, which corresponds to missense mutation.
Normal hemoglobin protein in a RBC
DNA CTG ACT CCT GAG GAG AAG TCT
Amino acids Leu Thr Pro Glu Glu Lys Ser
Sickle cell hemoglobin protein in a RBC
DNA CTG ACT CCT GTG GAG AAG TCT
Amino acids Leu Thr Pro Val Glu Lys Ser
When GAG is transcribed to mRNA, the CUC codon is obtained, which codes for glutamic acid. Thymine substitution causes the DNA sequence to change to GTG, which is transcribed as CAC, the codon that encodes the amino acid valine. The change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease.

Describe the rate of division of cancer cells
Answer: God bless you
Explanation:
Cancer cells divide without a 'go' signal. Normal cells cease dividing when DNA is damaged, but cancer cells continue. 'Daughter' cells with aberrant DNA or chromosomal numbers result.
What are cancer cells?Cancer cells are able to divide even if they have not received the signal that says "all clear." Cancer cells, on the other hand, will continue to divide even in the face of genetic (DNA) damage, which causes normal cells to cease dividing. "Daughter" cells are the end product of this process, and they are characterized by aberrant DNA as well as abnormal numbers of chromosomes.
It is possible for cancer cells to detach from the primary tumor and migrate through the circulatory or lymphatic systems to other parts of the body, where they can then form new tumors after emerging from the blood or lymph vessels. This process is known as metastasis. Cancer is a disease that is created when cells divide without control and spread into the tissues that are in close proximity to them.

Cindy/was diagnosed with anemia recently, because her physician found that her blood contains a lower count of red blood cells than normal. 4 A) What is anemia's immediate impact on gas exchange?
Answer:
The correct answer would be - a decrease in the numbers of RBCs will lead to a decrease in the ability for gas exchange in a person.
Explanation:
In the case of anemia, there would be a decrease in the number of RBCs that might be due to increased destruction of these cells, or low production of RBCs, that transporting oxygen and carbon dioxide affects the ability for gas exchange in an individual.
RBCs carry and transport oxygen to various body parts and then carry back carbon dioxide from different parts of the body to the lungs for gaseous exchange but with less number of RBCs leads to impair or decreased gas exchange in the case of anemia.
