You have already learned about the formation of metamorphic, sedimentary, and igneous rocks. Use what you know to construct an explanation about how you think melted rock deep within Earth could change over time and one day look like the image on this page.
The solid Earth (the mantle and crust) is made of rock. You may have noticed that there are many kinds of rocks, from the soft sandy rocks that form the cliffs at Scripps beach to the hard rocks that form the mountains to the East of San Diego. Geologists have developed a way of classifying the various rocks and understand fairly well where they come from and where they go. There are three general types of rocks, those that form from melt (igneous rocks), those that are deposited from air or water (sedimentary rocks), and those that have formed by "cooking" or otherwise altering another rock (metamorphic rocks). Sedimentary rocks form by breaking down other kinds of rocks into small particles and washing or blowing them away; metamorphic rocks form from other rocks and igneous rocks form by melting other rocks. Thus rocks are always changing form and are as part of a giant cycle of renewal. This cycle is called the Rock Cycle.

How can each copy of DNA at the end of replication be compared?
A. Each copy is identical to each other
B. Each copy is different from each other
C. They are 90% similar
D. They are 50% similar
Answer:
At the end of DNA replication, each copy is identical to each other (option A).
Explanation:
The concept of DNA replication implies that, from an original molecule, two identical molecules are obtained.
DNA replication is based on a semi-conservative model, since the double strand is separated, and each strand serves as a mold for the synthesis of a new strand. At the end of the replication, two identical DNA molecules will be obtained, each consisting of an original strand and a new one.
The best evidence that the replication process results in two identical molecules is that, otherwise, an individual's genetic information could vary, which does not happen.
The other options are not correct because:
B. The copies cannot be different.
C and D. They are 100% identical, not partially (50 or 90%) similar.

What is the level of organization?The level of an organization defines the relationship starting from simple to complex arrangements. It starts with the most simple and small order and further goes up to the complex and largest structures.
The molecules are the smallest structures after an atom that combines to form a cell. The cell is the fundamental unit that combines together to make a tissue that further forms an organ. The different organs combinedly form an organ system and finally an organism.
Therefore, the molecule is the simplest and the organism is the most complex.

if genes are on different chromosomes, the law of independent assortment states that -
gene pairs always stay together
half an organism's gametes have one allele per pair
gene pairs segregate randomly and independently of each other.
one allele is always dominant
Answer:
Gene pairs segregate randomly and independently of each other.
Explanation:
Genes are the basic units of hereditary and are located on chromosomes. According to Gregor Mendel's law of independent assortment which states that the alleles of two (or more) different genes are sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele the same gamete receives for another gene.
For example, in a the pea plants used by Mendel in his studies, the genes for seed shape and flower color were inherited independent of each other by the offspring of the parent pea plants. Therefore, Mendel concluded that the inheritance of each trait was independent of the other.
Answer:
gene pairs segregate randomly and independently of each other
Explanation:
According to the Law of Independent Assortment, if two genes are on different chromosomes, then the alleles for these genes separate independently of each other during the formation of eggs or sperm.
This means that genes separate independently of one another. This explanation most closely matches C) gene pairs segregate randomly and independently of each other.

Fully explain how cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.
Cellular respiration is a metabolic process called cellular respiration that converts glucose to ATP.
What is cellular respiration?Cellular respiration has the processes: Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the phases of cellular respiration.
A glucose molecule gradually decomposes into carbon dioxide and water during cellular respiration. In the process of transforming glucose, some ATP is directly created.
But far more ATP is later created through a procedure known as oxidative phosphorylation. The electron transport chain, a collection of proteins enmeshed in the inner membrane of the mitochondrion, is what drives oxidative phosphorylation.
Therefore, Cellular respiration is a metabolic procedure by which glucose is changed into ATP.

Which of the following correctly explains the difference between mitosis and meiosis?
Answer:
Below is a definition of the distinction between mitosis as well as meiosis.
Explanation:
Mitosis:
The genetic information (DNA) in something like a cell throughout mitosis has been duplicated as well as split evenly into two cells. An orderly sequence of circumstances known as the cell cycle moves through it's dividing cell.Meiosis:
Meiosis seems to be the mechanism whereby the gametes throughout sexually reproducing individuals are produced. Gametes have been formed in gender gonads and just like the new cells, constitute two complete sets of chromosomes.If you construct a model that places a cell with an internal salt concentration of 0.02 M in an aqueous solution that has a salt concentration of 0.015 M, what would cause the cell to lose internal pressure?
a. Active transport of water against the gradient
b. Diffusion of water with the pressure gradient
c. Osmosis of water flowing from where the solute is least concentrated
d. Passive transport of water with the gradient
A model that places a cell with an internal salt concentration of 0.02 M in an aqueous solution that has a salt concentration of 0.015 M would be because of the Active transport of water against the gradient. It is transported from the condition of high osmolarity to a solution of lower osmolarity.
What is active transport ?Active transport is the process which is helped up by the active ions and active channels that help to maintain the balance and transportation of molecules in the membrane.
The concentration mentioned in the equation is the concentration that is like the concentration of higher osmolarity and the flow will continue to the concentration of lower osmolarity across the semi permeable membrane. Water is transported against its concentration gradient.
Diffusion is the movement of higher concentration to the lower concentration through a semi permeable membrane. Osmosis is opposite to it.

Scientists have evidence that Glossopteris was found in what is now India, Antarctica, Australia, and Madagascar. What does this tell you about the position of the continents 225 million years ago?
Answer:
these continents were joined as a single landmass
Explanation:
Alfred Wegener proposed the 'Continental Drift Hypothesis' which stated continents were joined into a single great landmass called Pangaea. Pangea was a supercontinent that was assembled during the late Paleozoic and early Mesozoic eras, from about 330 to 200 million years ago. During the early Mesozoic, Pangea began to separate into continents observed today. It is for that reason that the same fossils can be found in very different geographic-climatic regions, evidencing that in the past continents were joined into larger landmasses.

During metaphase 1, the chromosomes line up in the middle of the cell. The way the chromosomes line up is ________ , or independent. This independent alignment results in different possible arrangements or assortments of chromosomes during metaphase. This in turn results in different __________ of chromosomes in _____
cells. During sexual reproduction, the traits that are determined by the genes on these chromosomes are passed on from parents to offspring.
Answer:
During metaphase 1, the chromosomes line up in the middle of the cell. The way the chromosomes line up is random, or independent. This independent alignment results in different possible arrangements or assortments of chromosomes during metaphase. This in turn results in different sets of chromosomes in daughter cells. During sexual reproduction, the traits that are determined by the genes on these chromosomes are passed on from parents to offspring.
Explanation:
In metaphase, the typical chromosome is formed by two chromatids joined by a centromere. Each chromatid is composed of a sequence of chromatin ringlets domains. During metaphase I, fibers of the spindle apparatus capture chromosomes and take them toward the center of the cell, to the metaphase plate. Each chromosome of the pair joins with a microtubule of only one of the spindle poles, so the two equivalent chromosomes join the fibers of opposites poles.
The homologous pairs of chromosomes get aligned in the metaphase plate for their posterior separation in anaphase I. When they align in the center of the cell, their orientation is random.

How are influenza viruses classified?
by their type of movement
by their protein structure
by their genetic material
by their different shapes
Answer: They are classified by subtypes based on the properties of their hemagglutinin (H) and neuraminidase (N) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers.
1.There movement: People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
2. There protein structure: The influenza viruses are classified into types A, B, and C on the basis of their core proteins. Type A viruses are further subdivided according to their envelope glycoproteins with haemagglutinin (HA) or neuraminidase (NA) activity.
3. There genetic material: by subtypes based on the properties of their hemagglutinin (H) and neuraminidase (N) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers – e.g., A(H1N1), A(H3N2)
