Society is like a biological organism, with each organ dependent on the others for survival is true.
The dominant-recessive link between the C and c alleles can be used to explain this outcome. Each offspring of two heterozygous dogs (C/c) has a 50% chance of getting either the dominant C allele from one parent or the recessive c allele from the other. In this instance, the smooth-haired puppy (c/c) expressed the smooth hair phenotype due to inheriting two copies of the recessive c allele.
The genotype of the parents can be deduced from the phenotype of the offspring, but without additional genetic testing, it is not possible to know the precise combination of alleles that each parent contributed to the offspring.

after taking a bite of pizza, sensory receptors are stimulated in your mouth. what is the order of information flow that results?
Correct order of information flow is :Stimulation of sensory receptors → impulse sent to CNS → sensation → perception.
A significant job of sensory receptors is to assist us with finding out about the environment around us, or about the condition of our inner environment. Various kinds of upgrades from shifting sources are gotten and changed into the electrochemical signs of the sensory system. This cycle is called tactile transduction. This happens when a boost is identified by a receptor which creates a reviewed expected in a tactile neuron.
On the off chance that sufficient, the evaluated potential makes the tactile neuron produce an activity potential that is transferred into the focal sensory system (CNS), where it is coordinated with other tangible data — and in some cases higher mental capabilities — to turn into a cognizant view of that upgrade. The focal incorporation may then prompt an engine reaction.

which of these associations is incorrect? question 4 options: sclerenchyma cells-cell division stomata-gas exchange sieve-tube cells-sugar transport epidermal cells-protection xylem cells-water transport
Among these, Sclerenchyma cells-cell division is incorrect. As sclerenchyma is a form of plant permanent tissue. Cell division is lost in permanent tissues.
The Sclerenchyma is responsible for the structural support of the plant. Scleral tissue is part of the three types of terrestrial tissue present in plant systems. Dural tissue does not divide and becomes dead cells as it matures. These dead cells are high in lignin and unable to follow Cell division. So this is the wrong cell to function mapping.
Sieve tubes are responsible for transporting nutrients around the plant, so sugar molecules pass as part of the phloem. Xylem transports water throughout the plant system. Stomata serve as pores through which gas exchange takes place between the atmosphere and plant cells. Epidermal cells form the outer covering structure that helps protect the internal structure of the plant.

which events are thought to have played an important role in the evolution of eukaryotic cells? select all that apply.
All of the mentioned events are thought to have played an important role in the evolution of eukaryotic cells.
Eukaryotic cell evolution is thought to have been influenced by a number of key events, including the following:
1. Theory of endosymbiosis: The most widely accepted explanation for how eukaryotic cells came to be is this one. It asserts that symbiotic interactions between primitive prokaryotic cells like bacteria and archaea led to the development of eukaryotic cells. The first mitochondria, which are the organelles that are in charge of cellular respiration, were formed when one of these bacteria was taken over by another and evolved.
2. Diversification and duplication of chromosomes: In comparison to prokaryotic cells, eukaryotic cells have significantly more complex multiple linear chromosomes. Multiple rounds of chromosomal duplication and diversification are thought to have led to this complexity.
3. Nuclear envelope development: Eukaryotic cells are distinguished by the nuclear envelope, which separates the nucleus from the cytoplasm. It is thought that this structure evolved to protect the chromosomes and control how materials move between the nucleus and cytoplasm.

3. what is the main purpose for fermentation reactions?multiple choice 3create alcohol as a nutrient for further processingproduce carbon dioxideregenerate nad molecules for glycolysisproduce more atp per glucose than glycolysis alone
Fermentation reactions are used to regenerate NAD molecules for glycolysis, resulting in more ATP per glucose and creating alcohol as a nutrient and carbon dioxide as a byproduct.
What is fermentation?Fermentation is the metabolic process through which sugars and other organic substrates are converted into acids, alcohols, and other compounds. It is an old method of producing beer, wine, bread, yoghurt, and other foods. Yeast or bacteria convert sugar into carbon dioxide, alcohol, or acids during fermentation. Fermentation products might differ based on the type of organism and the conditions under which it is cultivated.
Fermentation processes are mostly used to renew NAD molecules for glycolysis. When glucose is broken down by glycolysis, two molecules of NAD+ are used. These two molecules must be regenerated in order for glycolysis to proceed. This is accomplished by fermentation processes that convert NADH back into NAD+. This permits glycolysis to continue, resulting in more ATP per glucose produced than by glycolysis alone. Furthermore, certain fermentation activities release carbon dioxide as a byproduct while producing alcohol as a nutrient for further processing.

the base composition of a double-stranded dna molecule is 27% adenine. what percentage of this molecule is the base guanine?
The percentage of base guanine in a double-stranded DNA molecule having 27% adenine will be 23% according to the Chargaff's rule.
DNA stand for Deoxyribonucleic acid. It is a genetic material formed of sugar, phosphate group and nitrogenous bases. The nitrogenous bases are of 4 types: adenine(A), guanine(G), cytosine (C) and thymine (T). The adenine bonds with thymine and the guanine bonds with cytosine.
Chargaff rule says that the sum of A and G is equal to the sum of C and T. Also it stated that the percentage of A and T are same in a DNA strand and similarly the percentage of G and C are equal because they bond with each other. Thus, if adenine is 27% then guanine will also be 27% making a total 54%. Thus remaining 46% is half guanine and half cytosine.

When Mendel crossed the pollen from a plant with green pods with a plant with yellow seed pods and observed that all of the offspring had green seed pods, he concluded that green seed pods were dominant over yellow seed pods.
This observation led Mendel to develop his theory of inheritance, which is now known as Mendel's laws of inheritance. Mendel's laws state that traits are passed from parent to offspring as discrete units, now known as genes, and that one form of a gene (allele) can dominate over another.
In this case, the green seed pod allele was dominant over the yellow seed pod allele, which means that when the two alleles were present together, the green seed pod trait was expressed.
Mendel's experiments with pea plants helped to lay the foundation for the field of genetics, which is the study of how traits are passed from one generation to the next. The laws of inheritance that Mendel discovered are still used today to explain the transmission of traits in organisms, including humans.

Gametes contain only half the genetic material of the organism, and when two gametes combine during fertilization, the two halves combine to form a complete genome. Gametes are essential for sexual reproduction, and the process of combining gametes to form a new organism is called fertilization. During fertilization, the egg cell and sperm cell fuse together to form a single cell called a zygote, which will then develop into an embryo.
