Predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein instead of free in the
culture.
Answer:
Since the cell membrane is semi-permeable, the likelihood of substance L entering the cell attached to a large protein is lower than that of substance L free in the culture. Substance L enters the cell membrane through active transport, but the cell membrane may block the larger protein, thus blocking substance L, if it is attached to the large protein.

In snapdragons, flower color is determined by a gene with two alleles. Red flower color (R) shows incomplete dominance over the gene for white flower color (R'). A scientist is observing the genes and genotype of a snapdragon population. Which observation provides evidence that the population is evolving?
A) The alleles R and R' have unequal frequency in the population.
B) The population is decreasing, and the allele frequencies remain the same.
C) The allele R' is becoming more common in the population.
D) The population is increasing, and the allele frequencies remain the same.
Answer:
C) The allele R' is becoming more common in the population.
The observation from this experiment provides the evidence that the population is evolving and the allele R' is becoming more common in the population. Thus, the correct option is C.
What is Incomplete dominance?Incomplete dominance is the form of gene interaction which results from a cross in which each of the parental contribution is genetically unique and the allele gives rise to progeny whose phenotype is intermediate of the two parental genotypes and phenotypes. Incomplete dominance is also referred to as semi-dominance or partial dominance. It is an exception of the Mendel's law of dominance.
From the observation made in the experiment, it can be said that the allele R' which is responsible for white colored flowers in the plant are becoming more common in the population.
Therefore, the correct option is C.

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.
Directional selection only occurs in response to naturally occurring events.

The diagram below shows the Moon's orbit around Earth. Letters A, B, C, and D represent four positions in the Moon's orbit.
What is the approximate length of time it takes the Moon to travel from position A to position C?
1 day
14 days
28 days
31 days
Answer:
14 days is the correct answer. Since it takes 27(approx) days to complete one revolution of the earth and will take (27/2=14) days to complete half of the revolution I.e. A to C.
The orbit of the Moon around Earth is shown in the diagram below. Four locations in the Moon's orbit are represented by the letters A, B, C, and D.
How long does it typically take the Moon to move from position A to position C?
The Moon takes 28 days to go from location A to position C, which is a rough estimate. The Moon is at perigee, or its closest point to Earth, at position A. The Moon is at its apogee, or furthest point from Earth, at location C. Even though the Moon's orbital speed varies, it does take about 28 days to go from perigee to apogee. The Earth's orbit around the Sun and the Moon's orbit are both inclined.
This indicates a tilt between the orbital planes of the Earth and the Moon. The Moon's location with relation to the Sun consequently shifts throughout time. The Moon appears to "wax" and "wane" in the night sky because of this. The 28-day synodic period of the Moon accounts for the Moon's shifting positions with respect to the Sun.
Therefore, it may be concluded that it takes the Moon 28 days to roughly travel from place A to position C. This is due to the Moon's relatively slow orbital motion, which takes around 28 days to complete from perigee to apogee and from one place in relation to the Sun to another.

Explanation:
Independent assortment is the exchange of genetic material between
homologous chromosomes.
True Or False
Answer:
False
Explanation:
According to Gregor Mendel in his law of INDEPENDENT ASSORTMENT, independent assortment of genes is a phenomenon whereby the segregation of the alleles of one gene into gametes occurs independently of the alleles of another gene i.e. their segregation does not affect/influence one another. Independent assortment occurs in the Metaphase 1 of meiosis 1, where homologous chromosomes randomly align at the equator of the cell. This random orientation of homologous chromosomes determines which chromosome will separate into which gamete.
According to the question, the exchange of genetic material between homologous chromosomes is termed CROSSING-OVER. Crossing over or Recombination occurs during the Prophase I state of meiosis I, where non-sister chromatids of homologous chromosomes exchange a portion of their gene.
Hence, the answer is false because the exchange of genetic material between homologous chromosomes is crossing-over.

While Congress has the power to create new laws, they can be vetoed by the President. In addition, the Executive Branch must enforce these laws. What two
different constitutional principles are demonstrated by these relationships?
Select one:
A
checks and balances and separation of powers
B.
separation of powers and eminent domain
C
federal supremacy and due process
D.
separation of powers and quartering of troops
Answer:
A, Checks and balances and separation of powers.
Explanation:
Answer:
The correct answer is:
checks and balances and separation of powers
Explanation:
The system of checks and balances refers to instances in which the powers of the branches of government overlap, such as the Executive and the Legislative branch both having some power over the acts passed by Congress. Separation of Powers refers to instances in which separate branches have completely separate responsibilities, as in creating, interpreting, and enforcing the laws. Both of these doctrines are in place to ensure no branch gains too much power.
