Most of the weathering of Cleopatra’s Needle is caused by ____.
Question 16 options:
hydrolysis
chemical weathering
oxidation
frost wedging
Answer:
chemical weathering
Explanation:
The Cleopatra's Needle is a monument in New York. Its origin actually lies in Egypt, and it has been in Egypt for over 3,000 years, but it has been sent to New York as a gift for the United States by the Egyptians. While the monument already was partially damaged by weathering in the desert in Egypt, the weathering increased significantly ones the monument was brought in New York. The chemical weathering in New York has been much stronger, with constant acid rains and freeze-thaw cycles doing a lot of damage to the red granite by which the monument is made off. A plan has been made to preserve it, as its surface has been totally damaged, with the hieroglyphs nowhere to be found.
Which of the following best describes the main purpose of the combined processes of glycolysis and cellular respiration?1 breaking down ATP, so that ADP and P can be reused2. producing complex molecules from chemical building blocks3 the breakdown of glucose to carbon dioxide and water4 transforming the energy in glucose and related molecules in a chemical form that cells can use for work5 catabolism of sugars and related compounds
Answer:
4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work
Explanation:
Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.
The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.
Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.
Which enzyme breaks the hydrogen bonds during replication?
The enzyme known as helicase plays a pivotal role in the process of DNA replication by effectively breaking the hydrogen bonds that exist between the two complementary strands of DNA.
Explanation:Helicase, a vital enzyme in DNA replication, assumes the crucial task of unwinding the DNA double helix. Its primary function is to disrupt the hydrogen bonds, which are responsible for holding the two strands of DNA together. As these bonds are severed, the DNA strands separate, providing access to the genetic information they contain. This initial unwinding step is essential for DNA replication to proceed accurately and efficiently.

The enzyme responsible for breaking hydrogen bonds during DNA replication is DNA helicase. It unwinds the double-stranded DNA, separating the strands for replication.
During DNA replication, the enzyme responsible for breaking the hydrogen bonds between the complementary nitrogenous bases is called DNA helicase. DNA helicase plays a crucial role in the unwinding of the double-stranded DNA molecule. It functions by traveling along the DNA double helix, using energy from ATP hydrolysis to separate the two strands by disrupting the hydrogen bonds that hold the base pairs together.
As DNA replication progresses, the leading and lagging strands are exposed, making them accessible for the replication process. DNA polymerases can then synthesize new complementary strands on each of the separated parent strands. This process ensures the accurate duplication of genetic information by unwinding and separating the DNA strands and allowing them to serve as templates for the synthesis of new DNA molecules.

Which of the following describes a phenomenon that occurs when we observe plants that wilt?
A. The xylem releases all its water.
B. The stomata close, cutting off transpiration and gas exchange.
C. The roots begin to rot, causing them to no longer uptake water.
D. The plant begins absorbing oxygen and releasing carbon dioxide into the atmosphere.
Answer:
A: The xylem releases all it's water
Explanation:
This is so because wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The rate of loss of water from the plant is greater than the absorption of water in the plant.

Which of the following would be a body response when stepping outside without a coat on a snowy day?
A. Blood vessels in the skin narrow and contract.
B. More liquid is transported by the body to the skin for insulation.
C. Sebaceous glands secrete more sebum.
D. Blood vessels in the skin expand
Answer:
A. Blood vessels in the skin narrow and contract.
Explanation:
If we will step outside without a coat on a snowy day then our blood vessels in the skin will become narrow and contract. It is a mechanism to conserve heat within our body in cold weather. If the blood vessels in the skin will become narrow and contract then less blood will flow in the blood vessels, this phenomenon is known as vasoconstriction. The blood of our body is warm but the exposure to the cold weather will cause the heat of the blood to dissipate into the environment. But constricted blood vessels will have less blood and hence heat loss is minimized which keeps the internal temperature of the body as normal even if outside environment is cold.
Answer:
A. Blood vessels in the skin narrow and contract.

Answer:
D. only about 1.5% of the oxygen carried in dissolved form is correct answer.
Explanation:
Plasma is a component of blood, it has many functions in our body like fighting against diseases, clotting the blood.
In the plasma, the quantity of oxygen in solution is about 1.5% of the oxygen carried in dissolved form and 98.5% of the oxygen is bound to hemoglobin.
Thus option (D) only about 1.5% of the oxygen carried in dissolved form is correct.
In the plasma, only 1.5% of the oxygen is carried in dissolved form. Most oxygen is carried by hemoglobin in red blood cells.
Explanation:In the plasma, the quantity of oxygen in solution is generally quite small. The correct answer is D. only about 1.5% of the oxygen carried is in dissolved form. Most of the oxygen in the blood is actually carried by hemoglobin, a protein found in red blood cells. Hemoglobin binds to oxygen in areas of high oxygen concentration, such as in the lungs, and releases it in areas of lower concentration, such as in the body's tissues. Only a small fraction of the oxygen — about 1.5% — is dissolved directly into the plasma.

Tall height is dominant to short height in pea plants. You have a tall pea plant that you cross with a short pea plant. What is the genotype of the tall parent if some of the offspring are short? The tall parent was homozygous dominant and the offspring were all homozygous dominant The tall parent was homozygous dominant There is not enough information to answer this question. The tall parent was heterozygous The offspring were all homozygous dominan
Answer:
The tall parent was heterozygous
Explanation:
If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.

General steps of the Scientific Method, in order:
1. Observe
2. Ask questions
3. Make a hypothesis
Final answer:
The scientific method is a structured approach to inquiry that includes steps such as making observations, asking questions, conducting research, forming hypotheses, testing these hypotheses, analyzing data, drawing conclusions, and communicating results.
Explanation:
The scientific method is a systematic approach to research and problem-solving in science. It follows a specific series of steps to ensure that conclusions are based on systematically gathered and analyzed evidence. The general steps, in order, are as follows:
Make observations: This is the process of gathering information about phenomena or systems of interest to prompt further investigation.Formulate a question: Based on initial observations, a specific question that seeks to explain the phenomena is posed.Conduct research: Investigate existing sources to understand what is already known about the subject or problem.Form a hypothesis: Develop a testable prediction that provides a possible answer to the research question.Test the hypothesis: Conduct experiments or collect data to test the validity of the hypothesis.Analyze the data: Look at the results to determine if they support or refute the hypothesis.Draw conclusions: Based on the data analysis, decide whether the hypothesis was correct. If the hypothesis is incorrect, consider alternative explanations.Communicate results: Share findings with others through publication, presentations, or other forms of dissemination.The scientific method is an iterative process, meaning that these steps are often repeated to refine hypotheses and increase the understanding of the subject matter.
