The light-independent reactions use stored chemical energy from the light-dependent reactions in order to fix carbondioxide gas and create a product that can be converted into glucose.
Define the process of photosynthesis?Photosynthesis is that kind of process in which green plants and organisms prepare their own food in the presence of sunlight to neutralize the reaction.
The process of photosynthesis takes place in two stages one stage is known as a light-dependent reaction while the other stage is known as a light-independent reaction.
ATP Synthase:
The ATP synthase is also known as a mitochondrial enzyme which is localized inside the inner membrane, where it catalyzes the synthesis of ATP from ADP and phosphate.
Calvin Cycle:
The process of the chemical reaction is performed by the plants for the reduction of carbon dioxide and other compounds into glucose.
Electron Transport Chain:
The electron transport chain is that chain in which a series of four protein complexes couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation.
Photosystem 1:
In this system, the proteins are responsible for the precise arrangement of cofactors and determining redox properties of the electron transfer centers.
Photosystem 2:
First of all the photosystem 2 precise arrangement of cofactors and determine the redox properties of the electron transfer centers.

What are some evidences that support evolution?
some evidences that support evolution are: anatomy, molecular biology, biogeography, fossils, & direct observation. Genes, which are passed from parent to kid during reproduction, express themselves in these traits.
Evolution is the gradual change in the hereditary characteristics of biological populations over many generations. Genetic recombination and mutation are the usual causes of variation within a population. Genetic drift and natural selection, two evolutionary processes that might lead to particular traits becoming more or less dominant in a population, are likely to occur in this variation. This is how evolution works. Heritable traits emerge over multiple generations in response to shifting evolutionary factors that determine whether a trait is prevalent or rare within a population.

Capillary action, which allows plant sap to flow through a tree, is the result of cohesion between water molecules. True False
Capillary action happens in light of the fact that water is tacky, on account of the powers of attachment (water particles like to remain nearby) and bond (water atoms are drawn in and stick to different substances).
The development of water particles in the plant body is because of the cement powers between the water atoms and surfaces of the root and stems. The durable powers present between the water particles keep them intact and back off their transportation.
Since water particles like to remain together (attachment) and like to adhere to the walls of the containers of cellulose (bond), they ascend the cylinders as far as possible from the roots to the leaves. Water then, at that point, dissipates from the leaves, assisting with drawing up additional water from the roots. This interaction is called hairlike activity.

What are the conclusion from Mendelian experiment?
Mendel gathered his data for tens of thousands of plants before coming to the conclusion that the traits might be divided into expressed and latent features. These traits were described by him as being dominant and recessive, respectively. In a hybridization, dominant features are those that are passed on unaltered.
The three laws of dominance, independent assortment, and segregation serve as a summary of all the findings of Mendel's experiment. He proposed that each gene be passed down to the organisms twice, once from each parent. In their gametes, organisms only share one copy of each gene. In his opinion, traits are discretely inherited from each parent, one at a time.

Of the following routes of administration, which will produce the fastest onset of effects? O Intramuscular injection. O Inhalation. O Using a rectal suppository. O Rubbing it on the head.
Intravenous injection is the most effective approach for quickly and accurately distributing a certain amount throughout the body. It is also used for irritating solutions that would cause pain and tissue damage if supplied by subcutaneous or intramuscular injection.
Intravenous therapy (IV therapy) is a medical practice that involves injecting fluids, medicines, and nutrients directly into a patient's vein. Intravenous administration is extensively used for rehydration or to provide nutrients to people who are unable or unwilling to swallow food or drink by mouth due to reduced mental states or other causes.
It can also be used to administer medications or other types of medical therapy, such as blood products or electrolytes, to balance electrolytes. Attempts to administer intravenous therapy date back to the 1400s, but the practice did not become widespread until the 1900s, after protocols for safe and successful use were developed.

The similar bone structure of different organisms and different its function is due to common ancestor. Homology similarity of the structure and physiology of different species of organisms due to their descent from a common evolutionary ancestor so we can say that these structural similarities are an example of homology.
Why are most point mutations harmless?
Most point mutations are harmless because the majority of the genetic code is non-coding, meaning that it does not contain instructions for making proteins.
Point mutations that occur in non-coding regions of the DNA will not affect the function of the proteins that are produced, and therefore, will not cause any harm.
Additionally, point mutations that occur in coding regions can sometimes result in a change in the amino acid sequence of a protein, but the change may not be significant enough to alter the protein's function. For example, a point mutation that changes one amino acid in a protein's sequence may not disrupt the protein's structure or function. This is known as a silent mutation.
Furthermore, some point mutations can even be beneficial by providing a selective advantage. For example, a point mutation that changes a codon for an amino acid to one that codes for a different amino acid but still allows the protein to function properly.

What is the genetic basis behind the appearance and gender of calico cats?
The gene for "orange or black coat" is on the X chromosome, so if "orange" and "black" are active in different cells, female cats can have both colors of calico cat's coat. Yes, because male cats only have one X. The chromosome is her only one of these colors.
The calico, or more specifically tortoiseshell, pattern of cats is observed in female (or rarely male XXY) cats with different alleles at the coat color locus on the X chromosome. One of the X chromosomes carries alleles for black fur pigment and the other for orange fur pigment. Random inactivation of one of the X chromosomes causes orange and black spots on the cat's coat. Males with a single X chromosome have either orange or black fur, depending on which allele they possess. Calico cats have large white spots along with orange or black spots on their fur due to an autosomal gene that causes white spots.

Which set of conditions would most likely cause a change in gene frequency in a population that reproduces sexually
Small population size is most likely to result in changes in allele frequencies in a population. So, the correct option is (B).
The relative frequency of an allele (gene variant) at a specific locus in a population, expressed as a fraction or percentage, is known as allele frequency or gene frequency. It is the proportion of all chromosomes in the population that carry that allele divided by the entire population or sample size. Microevolution is the change in allele frequencies that happens within a population over time.

if a cell contained three pairs of homologoues (n=3, 2n=6) how many configurations are possible?
Twice the number of chromosomes in a haploid cell (n).
How many chromosomal combinations are feasible in the gametes of a 2n 6 cell?The number of potential chromosomal pairings in gametes is 2n (two to the ‘n’ power, where ‘n’ is the number of chromosomes in the haploid set). So, for 2n = 4, n = 2, and gamete number = 22 = 4, the answer is 4. Furthermore, for 2n = 6, n = 3, and gamete number = 23, the answer is 8.
As a result, an organism with cells 2n=6 is diploid and contains 6 chromosomes in total. In other words, this creature contains three chromosomal pairs. We will use the formula nCr = n! / r! * (n – r)! to compute combinations, where n represents the total number of things and r indicates the number of items picked at a time.

Where is the most ATP produced in cellular respiration ?
The majority of ATP created during cellular respiration is used in the electron transport chain (oxidative phosphorylation).
Cellular respiration is the mechanism by which glucose molecules are broken down into [tex]CO_2[/tex] and [tex]H_2O[/tex] to provide energy from Adenosine Triphosphate (ATP). Additionally, cellular respiration often occurs in an organism's cells by turning the metabolic energy contained in foods into adenosine triphosphate. Additionally, it occurs in three steps, which are the TCA cycle, electron transport, and glycolysis (Oxidative phosphorylation). As a result, the stage of aerobic cellular respiration that produces the most ATPs is called oxidative phosphorylation.
Normally, ATP releases energy by dismantling any weak phosphate cells that may be present. The energy that is released as the phosphate cell disintegrates is then put to use. ADP is created after ATP.

What are the 3 events in meiosis that contribute to genetic variation ?
Crossing over, Independent assortment, and Random fertilization are the three meiotic events that affect genetic variation.
Crossing over: A process known as crossing over occurs when homologous chromosomes couple up and exchange genetic material during prophase I. Genetic variety is the outcome of this, which causes the development of chromosomes with novel gene combinations.
Independent assortment: The chromosomes arrange at random along the cell equator during metaphase I. This indicates that there is an equal likelihood for each pair of homologous chromosomes to be found in either daughter cell. Genetic variety results from the varied chromosomal arrangements in each daughter cell as a result.
Random fertilization: During fertilization, sperm and egg cells combine to form a zygote. Since sperm and egg cells are produced through meiosis, each one carries a unique combination of chromosomes.
