Only one of the two factors that control a trait is expressed when both types of factors are present best describes Mendel's law of dominance. Thus option D is correct.
what is Mendel's law?
According to Mendel’s Law of Dominance When an organism is mixture of heterogeneous trait, it expresses allele which are dominant, here the dominant trait always masks the recessive trait.
The trait is present in the form of two allele and one allele is dominant over the other allele which is recessive.
The dominant allele contributes exclusively to the phenotype of the offspring and Dominance can also be described as when one of the two alleles is non-functional means it does not produce a functional protein.
The recessive trait will be expressed only when both the allele are present in homozygous form from both parents.
Thus option D is correct.

Answer:
D bc it was on one of my test
Explanation:
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.

Sally
Sally thinks that the plants get food from the soil and that plants use their roots to take in the food they need for energy. She is worried that her plant will use up the soil in the Microworld and will run out what it needs for food.
Tanya
Tanya thinks that plants make their own food using air, water, and light. She thinks that as long as her Microworld is in the sun, the plant will have what it needs for food.
Richard
Richard also thinks that plants make their own food using air, water, and light. However, he is worried that there is not enough water or air in the bottle for his plant and that the plant will run out of what it needs to make food before the end of the project.

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.

Assume that producers in an ecosystem have 1,000,000 kilocalories of energy. How much energy is available to primary
consumers?
5. Which trophic level has the greatest biomass?
Therefore, according to this question, if it is assumed that that producers in an ecosystem have 1,000,000 kilocalories of energy; 10/100 × 1,000,000 = 100,000 kilocalories of energy will be available to primary consumers.
WHAT IS BIOMASS:The total biomass of an organism in each trophic level decreases going up. This is due to the lesser energy transferred from one trophic level to the next. As the trophic level increases, lower energy is available to convert into biomass. Hence, the higher the trophic level, the lower the biomass.Therefore, if this is the case, the producers at the first trophic level will contain the greatest biomass which will decrease as the food chain progresses upwards.
