Answer:
A) Decreases;increase
Explanation:
When there are high levels of carbon dioxide in the respiratory system, the blood pH level decreases, causing respiratory rate to increase.
This condition is acidosis because not enough CO2 escapes lungs hence CO2 accumulates and decreases pH of blood, making it more acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing to increase the amount of carbon dioxide exhaled to bring our body to the ideal pH.
Do you think that climate change has been presented to you as doom and gloom throughout your life? Explain.
Answer:
I believe that climate change is one of the most serious problems of young generations. At the current pace of greenhouse gas production global warming will increase exponentially, which will result in rising sea levels, certain animal species going extinct. Deforestation also severely adds to this problem as wood is a finite resource on Earth and the more trees we destroy the less oxygen there is relative to the amount of carbon dioxide in the atmosphere. This will continue to weaken the ozone layer which could result in catastrophe from sun flares or radiation. I do believe that in the near future drastic measures will be taken to prevent these events.

Sarah adds 10 g of baking soda to 100 g of vinegar. The mixture begins 20
to bubble. When the bubbling stops, Sarah finds the mass of the resulting
mixture. She determines its mass is 105 g. The data she collected is in the
table. Does this follow the law of conservation of mass? Explain.
Answer:
Yes, the reaction between baking soda and vinegar follows the law of conservation of mass.
Explanation:
The table and data was not attached to the question.
When baking soda and vinegar are mixed together, a chemical reaction occur resulting to release of gas (carbon dioxide gas)
Law of conservation of mass states that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.
That is mass of reactant = mass of product = 100g + 10g = 110g
Sarah got 105g as product because a gas of mass 5g was released during the reaction.
Sarah found the mass of the resulting
mixture without including the mass of the released gas.
A way to account for the mass of the gas is if the experiment is done in a closed system like zip lock bag to collect and account for the mass of the gas.
When this is done, the law of conservation of mass would be proven.

Mutations in genes cause
A. Variation
B. Competition
C. Reproduction
Answer:
Hello There the Correct answer is A. Variations.
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Explanation:
Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.
Answer:
The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.
The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.
The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.
Explanation:
The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.
In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.

Which best defines the population growth rate?
A. a. (birth rate + immigration) - (death rate + emigration)
B.(birth rate + fertility rate) - (death rate )
C.birth rate - death rate
Answer:
A a(birth rate+immigration)-(death rate)
A. (birth rate + immigration) - (death rate + emigration) best defines the population growth.
What is population growth?Population expansion is the term used to describe the increase in human population. Most of human history was marked by a rather stable population. However, innovation and industrialization made energy, food, water, and medical care more reliable and accessible.
The human population has grown dramatically over the last century. It has mostly accomplished this by producing copious amounts of food and figuring out how to deal with sickness. There may have been only a million people on the planet when mankind first developed agriculture ten thousand years ago.
Despite the fact that every demographic pyramid is different, most fall into one of three categories: expansive (young and rising), constrictive (elderly and shrinking), or stagnant (little or no population growth).

How would permeability change if types of channels in a neuron change?
Answer:
Explanation:
How the resting membrane potential is established in a neuron. ... Ions move down their gradients via channels, leading to a separation of charge that ... through brief, controlled changes in the permeability of their cell membrane to particular ... If you did this, you would measure an electrical potential difference, or voltage, ...
Membrane permeability is affected by temperature, the type of solute present, and the degree of cell hydration. Increasing the temperature makes the membrane more unstable and very fluid. Lowering the temperature slows the speed of the membrane.
Does the permeability change during the action potential?Action potentials, the main electrical signal produced by nerve cells, reflect changes in membrane permeability to specific ions.
The important point is that increasing Na + permeability causes more depolarization, resulting in the opening of more Na + channels and further depolarization of the membrane potential.
Membrane permeability to water and solute has been shown to depend on temperature, the osmotic pressure of the medium, the type of solute present, the degree of cell hydration, and the presence or absence of ice.
