Answer:

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.

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.​

Answers

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.

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.

Answers

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.

____ Free RNA nucleotides make complementary pairs between their own

Answers

Answer:

6, 5, 4, 2, 1, 3

Explanation:

Transcription refers to the process of the formation of RNA molecules from DNA molecules using DNA strands as a template.

Only one strand out of two DNA strands is involved in the process and the strand is known as coding strand which runs in the direction of 5' to 3'.

The process of transcription takes place in the following sequence:

1. Helicase enzyme binds to the DNA and unzips the two strands of DNA. This opens the helices of the DNA and the DNA gets open.

2. RNA polymerase binds to the promoter attached to the DNA and forms the single strand.

3. The RNA  nucleotides form complementary base pairs with the DNA and the RNA strand. A new complementary strand is made using complementary base pairing.

4. DNA helicase unzips the DNA and RNA hybrid.

5. The DNA and RNA get separated and the mRNA molecule formed in the nucleus exits the nucleus.

6. The two-strand of DNA is again joined via complementary base-pairing rule.

Independent assortment is the exchange of genetic material between
homologous chromosomes.
True Or False

Answers

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.

Which trend in hominid evolution can be supported by fossil evidence?
Walking upright
Use of tools
Increased intelligence
Decorating cave walls

Answers

Walking upright.

You can make a case for all of them, but for three of them indirectly.

But the answer, I think, is walking upright.


You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.

Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.

D.

Answers

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.
