What can scientists infer about the period of very early Earth from the fossilized remains of trees found under a lake?

Answers

Answer:There is a theory that terrestrial plants evolved from aquatic plants through a process of natural selection. Thus, by finding fossils of plants under the river, scientists may conclude that this theory is correct and that these fossils represent the ancestors of terrestrial plants.

The emergence of plants that survive on earth is a very important milestone for the planet, it is believed that these plants have evolved from green algae called Chlorophyta that have survived in marshy areas that had alternating periods of flooding and drought.Then the discovery of these fossils, through scientific experiments may conclude that the theory is correct

Explanation:

Answer:

The fossil record is the record of life on earth preserved in rock as fossils. The fossil record provides evidence of where types of plants and animals lived, how long they lived, how they died, and how they changed. It also tells us about Earth’s early environment and how it changed. The fossil record helps determine the age of rock formations by looking at how deep the fossils are buried in the rock. When a fossil is found above another fossil in a rock formation, the deeper fossil are considered older.

____ The DNA “rezips,” reforming the original complementary cross-strand

____ The DNA and messenger RNA strands separate from one another and the
RNA leaves the nucleus
____ Helicase “unzips” the DNA-RNA hybrid
____ RNA polymerase joins the new RNA nucleotides into a single strand
____ Helicase “unzips” the DNA, opening the two strands of the double helix
____ Free RNA nucleotides make complementary pairs between their own
nitrogenous bases and the attached bases of the single DNA template
strand.

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.

False

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.

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.

I hope that helps.

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.

Environmental agencies throughout the world believe that humans have forced Earth out of its natural cycle. Consider the choices below as possible sources of empirical evidence for anthropogenic climate change. Which choice does not support this view?

Answers

Answer:

Human activities increases the concentration of oxygen in the atmosphere.

Explanation:

Human is not responsible for the balance of oxygen gas in the atmosphere because human takes oxygen from the environment for the production of energy in the process of respiration. Plants are the key factor for maintaining the oxygen concentration in the atmosphere. Human activities are the main reason of increasing carbon-dioxide and other harmful gases in the atmosphere and increases the air pollution and change in climate occurs.

B.

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.
