50. The flow chart below shows how a metamorphic rock can change into a
sedimentary rock. Which of these processes would be the correct label to
replace the question mark?
Metamorphic rock
Sediment
Sedimentary rock
Erosion
?
A) Cooling
B) Deposition
C) Melting
D) weathering
Answer:
The process that would be the correct label to replace the question mark in this question is:
B) Deposition
Explanation:
Deposition takes place after erosion of sedimentary rock. At this stage, the eroded sedimentary rocks build up under high pressure heat, wind, ice, water, and other natural forces to originate the rock formation cycle once again. Naturally, after deposition, the igneous rocks, which have then layered up sedimentary rocks to become metamorphic rocks.
Why the Carbon must be cycled through the carbon cycle?
Answer:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
In your experiment, you found the following offspring only:Tall green: 626 offspring.Tall yellow: 313 offspring.Short green: 309 offspring.Stay with your original hypothesis/assumption, test it using chi2 test and analyze the result (whether you want to reject the hypothesis and why).(6p)
Complete question:
1. You found a new species of garden pea and have decided to repeat Mendel’s experiments. You have obtained two true-breeding pea plants that are tall (T) with yellow pods (g), and short (t) with green pods (G), respectively. Capital letters indicate dominant traits.
a. What is the genotype and phenotype of the F1 generation? (2p)
b. You allowed self-fertilization in F1 generation and obtained F2 generation. Using Punnett square to obtain the phenotypes, genotypes and their respective ratios. (4p)
2. If you obtained 1248 offspring in the F2 generation in Question 1, calculate how many offspring of each phenotypic class you would expect to have. (4p)
3. When you finish questions 1 and 2, under what assumption/hypothesis did you perform your analysis/calculation? Is there an alternative assumption/hypothesis, which may result in a different conclusion? If yes, what is the alternative assumption/hypothesis and what kind of offspring and in what numbers do you expect to obtain? (4p)
4. You only need to answer A or B to get this 6p. Please indicate which question you are answering. In your experiment, you found the following offspring only: Tall green: 626 offspring. Tall yellow: 313 offspring. Short green: 309 offspring.
A: If you stay with your original hypothesis/assumption, test it using chi2 test and analyze the result (whether you want to reject the hypothesis and why).
B: If you believe that the alternative hypothesis fits better with your data, test it using chi2 test and analyze the result (whether you want to accept the hypothesis and why).

which term describes a pure substance that made up of only one type of atom
Answer:
Element
Explanation:
In chemistry, two substances are referred to as PURE SUBSTANCES. One of the pure substances is ELEMENT and the other is compound. An element is a pure substance that contains only one type of atom.
In an element, only one type of atom makes up the structure. For example, H2 (hydrogen) and O2 are examples of elements because they contain only hydrogen and oxygen atoms respectively

Even though chestnuts can regrow from their roots, this does not usually happen because
there are few root systems left in the forest.
chestnuts grow in regions prone to fires.
most forestry professionals no longer want to grow chestnuts.
new growth is stricken with the blight before it has the chance to mature.
Answer: New growth is stricken with the blight before it has the chance to mature.
Explanation:
American Chestnut trees can indeed regrow from their roots but due to the devastating effect of the chestnut blight, they have been unable to do this since the blight spread across the country.
The blight was introduced when Chinese chestnut trees were imported into the U.S. in the 20th century. It killed off most of the chestnut trees in the U.S. and attacks the tree again when it grows to around 6 meters bringing it down to its roots. This is why the American Chestnut is considered endangered.

Several examples of antisense RNA regulating translation in bacterial cells have been discovered. Molecular geneticists have also used antisense RNA to artificially control transcription in both bacterial and eukaryotic genes. To inhibit the transcription of a bacterial gene with antisense RNA, what sequence might the antisense RNA contain
Answer:
An antisense sequence with complementary to the target mRNA encoded by the gene of interest
Explanation:
An antisense sequence is usually a short RNA sequence specifically designed in the laboratory to bind by complementary to the DNA/RNA sequence of interest (usually a target mRNA) whose expression is desired to be inhibited. When an antisense bind to its target mRNA, the antisense sequence acts to block translation, thereby inhibiting protein synthesis. Moreover, it has been shown that the double-stranded antisense-RNA complexes may also increase the susceptibility of the target sequence to RNase H digestion.

Which of the following is a true statement? Physical property change is always better than chemical property change.
o Physical and chemical propery change can happen at the same time.
Chemical property change is better than physical property change.
Answer:
the second one
Explanation:
Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Since the chemical identity of the matter in question is unchanged, this process represents a physical change.
Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the reactants and products are different.
none are better, depending on for what

explain the following type of respiration with diagram in toad:
1..Buccal respiration
2..Cutaneous respiration
3.. Pulmonary respiration
Answer:
1.Buccal pumping is "breathing with one's cheeks": a method of ventilation used in respiration in which the animal moves the floor of its mouth in a rhythmic manner that is externally apparent.
2.Cutaneous respiration, or cutaneous gas exchange, is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs.
3.Pulmonary ventilation is commonly referred to as breathing. It is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation.
