Answer: Widespread damage to mitochondria causes cells to die because they can no longer produce enough energy. Indeed, mitochondria themselves unleash the enzymes responsible for cell death.

What is an observational study? How is it different from a controlled experiment?
Answer:
Observational study is when you observe your subject and take more notes rather that writing down quantitative data. Meanwhile, a controlled experiment is more quantitative.

what is the molarity
Answer:
Hope its help you
if wrong then sry
Answer:
Explanation:
the number of moles of solute per liter of solution. molar concentration
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution. Explanation: To get the molarity, you divide the moles of solute by the liters of solution. Molarity=moles of solute liters of solution. For example, a 0.25 mol/L NaOH solution contains 0.25 mol of sodium hydroxide in every litre of solution.

Explain the strengths and weaknesses of Lamarck's theory of evolution.
There is no experimental proof of the lamarckism. New organs are not formed in organisms by their wish or requirement. 3.It is not necessary that an the acquired characters transmit into new
Answer:
Weaknesses are traits may stay around for longer that what their needed and Strengths are we adapt to our needs.
Explanation:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.

Explain the difference between independent variables, dependent variables, and control variables.
Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.

Which of the following will most likely decrease genetic diversity?
А increased reproduction
B selective breeding
C mutations
D immigration
Selective breeding dangers reduced genetic diversity can result in certain insects or diseases attacking, which could be quite devastating. Thus, option B is correct.
What is the cause of selective breeding in genetic diversity?Selective breeding can contribute to a large reduction in the genetic diversity of farmed populations, endangering long-term evolutionary progress and limiting populations' ability to adjust to environmental changes.
Unknowingly selecting uncommon illness genes as part of a desirable characteristic might cause difficulties with particular organisms, such as the high prevalence of deafness in Dalmatian dogs.
Genetic diversity is typically reduced by selective breeding, since only a few individuals are employed to produce enormous numbers of offspring. The population's survivability may be impacted by this.
Therefore, selective breeding will most likely decrease genetic diversity.

Describe how the mutation has effected the protein coded by this gene?
Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition.

Answer:
Mucous membranes
Explanation:
The epidermis (external) and mucous membranes (internal) represent the first non-specific barriers that act against invading pathogens and harmful substances. The mucous membranes separate the external environment surrounding the mucous cells from the body's internal environment. These membranes are considered as selectively permeable barriers that act to prohibit the passage of pathogenic microorganisms (e.g., bacteria) and harmful agents (toxic chemical substances).
Which of the following is NOT a common element in the human body? Select all that apply.
Answer:
Helium and carbon dioxide
The elements that are not common in human body are carbon dioxide and helium. The correct options are B and E.
What are elements?A chemical element is a type of atom with a specific number of protons in its nucleus, including the pure substance made up entirely of that species.
Chemical elements, unlike chemical compounds, cannot be broken down into simpler substances by any chemical reaction.
The human body is made up of only six components: oxygen, hydrogen, nitrogen, carbon, calcium, as well as phosphorus.
Sulfur, potassium, sodium, chlorine, and magnesium make up about 0.85% of the remaining mass. All 11 of these elements are necessary.
Carbon dioxide and helium are elements that are not found in the human body.
Thus, the correct options are B and E.

Answer:
3/4 (3 out of 4) of the genotypes are deaf. 3/4 is also equal to 75%. So 75% of the offspring produced will be deaf.
Explanation:
The way the punnet squares work is the top allele on the left combines with the left allele on the top, the top allele on the left is combined with the top allele on the right, the bottom allele on the left is combined with the top allele on the left, the bottom allele on the left is combined with the top allele on the right.

This model shows the process of protein synthesis including transcription and translation. What is the best explanation for what is
occurring at the arrow (translation)?
Answer: The answer is C
Explanation:
During the process of protein synthesis, the best explanation for what is occurring at the arrow is as follows:
The codon on the mRNA pairs with the anticodon on the tRNA which transfers amino acids into the proper sequence to form a protein.What is Protein synthesis?Protein synthesis may be defined as a biological process through which cells make proteins in order to accomplish metabolic functions that facilitate the survival of living organisms. The process of protein synthesis terminates with the help of two stages. They are as follows:
Transcription.Translation.Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. While the process of translation acquired the transfer of genetic instructions from the mRNA to the sequence of amino acids in order to form proteins. This takes place in the cytoplasm of the cell.
