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.

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.
Directional selection only occurs in response to naturally occurring events.
Please select the best answer from the choices provided
Тrue
False
Answer:
False
Explanation:
Directional selection is a force in nature that causes a population to evolve towards one end of a trait spectrum. This change happens gradually and is hard to notice over a short period of time. This change is consistent and constant.
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.

Which form of nitrogen is most abundant on earth? N2 (Atmospheric Nitrogen) NH3 (Ammonia) NO2- (Nitrite) NO3- (Nitrate)
Answer:
N2 (Atmospheric Nitrogen)
Explanation:
Nitrogen is a chemical element positioned as 7 on the periodic table. Nitrogen is found as a gas in the atmosphere (N2) and constitutes the most part of the air making it the most abundant gas on Earth.
Atmospheric nitrogen (N2) is the most abundant of its form found on Earth. It can be converted to its compound form e.g. nitrates (a plant usable form) by lightning and some bacteria in the soil.

Which would a microscope be LEAST useful in studying?
A. spider
B. amoeba
C. bacterium
D. paramecium
Answer:
A
Explanation:
spiders can be seen with the naked eye
Answer:
A
Explanation:
A spider is large enough to see and observe without a microscope. Bacteria, amoeba and paramecium are all very tiny, and can’t be seen with just our eyes. To see these things, we would need a microscope. Therefore, a microscope would be the least useful when studying A: a spider.

What characteristic makes a social group eusocial?
Answer:
Eusociality (from Greek εὖ eu "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non.
Explanation:
Answer: Eusociality (from Greek εὖ eu "nice" good and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non.
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.
