The nuclear equation shows the transmutation of a form of radon into polonium and an alpha particle. In one tho two sentences, explain whether or not the reaction is balanced.
Answers
The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

Answers
Answer:
Heredity,Genetics
Explanation:
Heredity is the passing of traits from generation to generation while Genetics is the scientific study of traits being passed from generation to generation.
Traits are the defining characteristics that are passed from generation to generation, and genetics is a branch of science to study heredity.
What is genetics?Genetics is the branch of science to study heredity and evolution, how genes originate and what changes occur over time.
Genes are segments of DNA upon chromosome code for protein, in the genetics gene is the major area of study. How a gene can be transferred from parents to a daughter and lead to heredity can be studied.
Heredity depends on the gene responsible for a particular trait and character, during evolution, there would be changes occur at the genetic level which leads to variation among species.
Therefore heredity is to pass traits, and the scientific study of it is genetics.

Section 3: For at least one of the sub-problems, propose two solutions based on the information from the lesson and your additional research. In the rationale column, explain how your solution restores the stability and biodiversity of your selected ecosystem.
Answers
Removal of invasive species and growing more vegetation can restore the stability and biodiversity of ecosystem.
These two solutions restores the stability and biodiversity of the selected ecosystem because invasive species can capture more resources as compared to local species which leads to the extinction of local species.
While on the other hand, growing more vegetation provides more food to the organisms which ultimately increases the biodiversity of the ecosystem so we can conclude that removal of invasive species and growing more vegetation are the solutions to bring ecosystem in a stable condition.

Why do fossils that paleontologists find represent only a partial picture of life in the past?
Answers
Answer:
Because we cannot see some animals properly like jellyfish as their tissue is too soft, and feathers or for can often not make an imprint on fossils.
Explanation:
Answer:
Fossils: They are remains of animals or plants in the past that were somehow preserved and buried under the earth's crust.
One fossil can only give us a glimpse into the history of the time that particular animal or plant lived or breathed on the earth. For example, a fossil remains of a particular species of dinosaur would only provide information of the time when that species lived on earth and other information related to that particular time. Fossil remains of dinosaurs would not give us information on the time during the ice age or any other time in history.Explanation:
The study of various fossils can give us information about the development and evolution of living organisms over time but there are limitations to it.It may happen if we compare the fossil remains of an organism that existed billions of years ago we may find a time gap where there is no fossil evidence found so it creates a loop in information.Also, the process of fossilization is complex and long. Many species of the past became extinct without fossilization so we can never get information related to those extinct species.Thus, because of this reason we can say that fossils don't provide us with complete information about the past.For more information:

Interferons (IFNs) — the body's first line of antiviral defense — are cytokines that are secreted by host cells in reaction to virus infection. by using inducing the expression of hundreds of IFN-inspired genes, numerous of that have antiviral capabilities, IFNs block virus replication at many ranges.

Where in the cell would you expect to find the greatest activity of the pyruvate dehydrogenase complex?
Answers
Answer:
Mithochondria
Explanation:
In eukaryotes, the pyruvate dehydrogenase complex, like the enzymes for citric acid cycle and oxidation of fatty acids, is located in the mitochondrion, where is associated with the surface of the inner membrane facing the matrix.
In the cell, mitochondria are the place where it expects to find the greatest activity of the pyruvate dehydrogenase complex.
What is the pyruvate dehydrogenase complex?The three-enzyme complex known as the pyruvate dehydrogenase complex (PDC) is responsible for pyruvate carbonylation, which converts pyruvate to acetyl-CoA.
This complex connects the glycolysis metabolic pathway to the citric acid cycle by allowing acetyl-CoA to be used to perform cellular respiration.
The enzyme pyruvate dehydrogenase catalyzes the reaction between pyruvate and a lipoamide, which yields acetylated dihydrolipoamide and carbon dioxide. The process requires the coenzyme thiamine pyrophosphate.
Therefore, the site where you find the greatest activity of the pyruvate dehydrogenase complex is mitochondria.
