Answer:
The main cause of earthquake is the motion of tectonic plates which occurs due to friction.
Explanation:
The tectonic plates moves slowly inside the earth crust but the edges of these plates stuck with each other due to friction that occurs during their contact. When these two plates detached from each other, the force of friction converts in a form of wave energy which can be observed in the form of earthquake. Divergent, convergent, and transform are the three types of plate boundaries which are responsible for earthquake.
Answer:
D) The plates smash together with no subduction

How did the death of chestnut tree result in the growth of the ecosystem
Answer:
add nutrients to the soil.
Explanation:
The death of chestnut tree result in the growth of the ecosystem because when the chestnut tree dies, the decomposers such as fungi and bacteria start feeding on the dead tree and as a result nitrogenous waste is produced mixed with soil which is the essential nutrient for the plants. These nitrogenous waste is used by the plants to make amino acids and as a result the growth of an ecosystem occurs.
A particular protein (Vac8) found in yeast has this N-terminal sequence, Met-Gly-Ser-Ser-Cys.... The corresponding DNA sequence in the coding strand is 5' ATG GGC TCA TCG TGC.... If the DNA sequence is mutated to 5' CTG GGC TCA TCG TGC..., what will happen to this VAC8 gene? (in RNA, CUG codes for Leu)
Answer:
The protein will not be synthesized because this point mutation produces the loss of the start codon (substitution of Met by Leu).
Explanation:
The mutations are changes in the DNA sequence that have diverse effects on protein synthesis. A mutation in the start AUG codon may lead to the reduction and even the elimination of protein synthesis. In consequence, this type of point mutation is usually referred to as 'start-loss mutation'.

You are now taking a ride on the Magic School Bus with Ms. Frizzle. This bus is magic because it can go anywhere within the body. Today’s lesson is on Central Dogma. Ms. Frizzle takes your class directly to the nucleus to start your field trip. Since this trip is about the central dogma, what three major cellular process will be involved? Where will you bus be going within the cell during each of these processes? For each process, describe in your own words and in general what is going on?
Answer:
See the answer below
Explanation:
The trip will involve a bit of stoppage inside the nucleus during which replication and transcription will take place before proceeding to the cytoplasm where synthesized mRNA will become translated into protein.
The central dogma refers to a series of processes during which genetic information in the DNA of a cell is encoded and expressed in living cells. The 3 major steps involved in these processes are:
1. Replication
2. Transcription
3. Translation
Replication involves the synthesis of a double-stranded DNA molecule from a template of another double-stranded DNA molecule within the nucleus. In order words, replication is a process during which a DNA molecule reproduces itself. Each of the strands of the DNA acts as a template for the synthesis of another new strand. Eventually, 2 new double-strand DNA molecules are formed each consisting of one old strand and one new strand.
During transcription, the information contained in deoxyribonucleic acids is encoded and transcribed into another molecule known as the messenger ribonucleic acid. This process happens in the nucleus of the cell.
After transcription and processing of the mRNA produced, the resulting mRNA is then transported to the cytoplasm where, together with the ribosome and transfer RNA, the encoded information becomes translated into protein. Each of the genetic codes in the mRNA is translated to their respective amino acids and the amino acids are linked together by peptide bonds to form a protein.

Answer: The attachment listed some cell organelles,although there isn't a specific question on then but am going to be defining each of them and state their functions as well.
1. The Nucleus; The is command centre of the cell, it is made up of nuleolus, chromosomes, nucleoplasm,nuclear envelope and nuclear lamina.
it contains the genetic/hereditary materials that the cell is made up of.
The Nucleus plays a great role in the control of growth and development of the cell.
The nucleus also coordinates some of the the activities of the cell like cell division and protein synthesis.
2. Cytoplasm; The cytoplasm is one of the cell organelles,it is the liquid portion of the cell,it consists of cell contents between the plasma and the cell membrane. The fluid cytoplasmic material is where many cell organelles are found/suspended fluid. Most activities carried out by the cell occurs in the cytoplasm.
3. Endoplasmic Reticulum; The Endoplasmic Reticulum is one of the cell organelles that have the structure of a network of flattened sacs and tubules and play a crucial role in plant and animal cell. Rough endoplasmic reticulum has ribosomes attached to the cytoplasmic side of the membrane and the smooth endoplasmic reticulum lacks attached ribosomes in them thus giving it the smooth appearance.
The Endoplasmic Reticulum functions in the production, processing, and transport of proteins and in and out of the cell and also the production of lipids.
4. Golgi Body; One of the plant organelles that plays a role in the sorting and organizing the proteins produced and processed by the Endoplasmic Reticulum. these proteins are sorted and packed in vessicles to be used by the body.
5. Mitochondria; (a double membrane organelle). It is otherwise known as the powerhouse of the cell,it produce/generate energy in the form of ATP needed for cellular respiration. These energy produced is used for other cellular metabolic activities.
6. Lysosome (Animal) Chloroplast (Plant); Lysosomes are found in most animal cells, they function by digesting good and garbage,they contains acids that aids this function in the stomach of the cell and when the lysosome is diseased or explodes,the cell stops functioning.
The Chloroplast on the other hand is found in the cells of plants and algae,they play a crucial broke in photosynthesis by capturing the energy from the sun and turning the captured energy into usable forms like sugar,glucose and other organic molecules.
7. Cell Membrane; The cell membrane is the cell organelle that forms a boundary between the cell and the sorounding environment.
The cell membrane as well controls the movement of cellular materials in and out of the cell.
8. Nucleolus; The nucleolus is one of the cell organelles where ribosomes are made. The ribosomes are small grain-shaped organelles that make protein and they are found in the surface of rough Endoplasmic Reticulum. Nucleolus are small and round in structure and are found in the nucleus,
9. Vacoule (Plant Cells) Centrioles (Animal Cells); The vacoule is a storage chamber(reservoir) for wanted and unwanted materials in the cell, the vacoule is found within the cytoplasm and it is enclosed by a membrane that typically contains fluid.
The centrioles on the part of the animal cell is a cell organelle that has a structure of a two hollow cylinders,ring of microtubules next to each other(the centrosome).the centrioles are located just outside the nucleus of the cell.
Centrioles function by producing the mitotic spindles for cell division, and also assisting to pull chromosome pairs apart to opposite end of the cell during cell division.
10. Cell Wall; A protective semi permeable rigid outer layer of nonliving material that surrounds the cells of plants and some other organisms.
The cell wall houses the organelles of the plant cell.
The cell wall functions by giving the cell strength and structure,it's semi permeable nature filters and selectively allows certain materials in and out of the cell.

Explanation:
If evolution is based upon there being genetic diversity between generations, how does the lack of genetic differences existing between daughter cells created via mitosis impact the theory of evolution
Answer:
See the answer below
Explanation:
If evolution is based upon genetic diversity, it means that evolution in organisms that only reproduce by mitotic division will depend largely on the frequency of random mutation of genes.
The only way that genetic diversity can occur between daughter cells formed from mitosis is if mutation takes place. Mutation general means a sudden change to the gene sequence of an organism.
Without mutation, evolution in mitotic organisms will be non-existence because there are no new genes or alleles being introduced into the gene pool.
How do catalyst work?
Answer:
Catalysts increase the reaction rate of a chemical reaction, allowing it to use less energy to start a chemical reaction and doesn't change the chemical properties or formulas.
Explanation:
What is a substrate? a molecule that acts as a catalyst a place where the reaction occurs a place on the product where the enzyme fits a reactant that is catalyzed by an enzyme
Answer:
a reactant that is catalyzed by an enzyme
Explanation:
Reactants are often referrred to as substrates as those are what enzymes mostly act upon to create products or some desired consequence
Option (d). a reactant that is catalyzed by an enzyme is called the substrate.
SubstrateA substrate exists as a molecule on which an enzyme acts. Enzymes catalyze chemical reactions that concern substrate, where the substrate binds to the enzyme's active site, and an enzyme-substrate complex is created. By action of the enzyme, the substrate exists transformed into a product, released from the active site, and free to obtain another substrate.
Enzyme catalysis exists as the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes exist in proteins, and most such processes are chemical reactions. Within the enzyme, naturally, catalysis happens at a localized site, called the active site.
The reactant in an enzyme-catalyzed reaction is named a substrate.
Because enzymes can expand reaction rates by enormous factors (up to 1017 times the uncatalyzed rate) and tend to be very precise, typically producing only a single product in quantitative yield, they exist the focus of active research.
Hence, Option (d). a reactant that is catalyzed by an enzyme is called the substrate.

In Pennsylvania, wolves have been extinct for many years. They used to feed on white-tailed deer, but not that the wolves are gone, the population of white-tailed deer has exploded. This means that this community:______
a. Was under top down control
b. Was under bottom up control
c. Lacks a fundamental niche for wolves
d. Lacks a fundamental niche for deer
Answer:
The correct answer is a: The community was under top-down control
Explanation:
Top-down control refers to scenarios where superior predators control the structure and dynamic of an ecosystem. These systems are affected by the presence/absence of the superior predator influences all the lower links in the trophic chain.
In the exposed example wolves, that are considered to be the top predators, affected the white-tailed deer populations being the cause of its decrease. As wolves used to feed on white-tailed deer, they kept these populations under control, but once the wolves got extinct, the deer population increased again. Probably, this explosion in the deer´s population also affected its lower link in the trophic chain.

The central (Haversian) canal that runs through the core of each osteon is the site of ________. adipose tissue and nerve fibers cartilage and interstitial lamellae blood vessels yellow marrow and spicules
Answer:
Blood vessels and nerve fibers
Explanation:
The Haversian canal serves as the bone tissues and it runs through the core of each osteon. The osteon surrounds the Haversian canal and contain structures called lamellae.
These lamella are made largely of collagen fibers and also various network of rich blood vessels and cells which produces blood cells in the body. Nerve cells which helps in the relay of impulses are also present. The rich contents of the bone gives it its strength and durability.
Answer:
The correct answer is: blood vessels and nerve fibers.
Explanation:
Haversian Canals are a group of tubes that are located in the more peripheral region of the bone, known as the cortical bone. The cortical bone is hard and compact and is composed of several concentric layers of bone cells (osteocytes and osteoblasts) that circle around a haversian canal, which contains capillaries and nerve fibers. This structure is called an osteon.
Haversian Canals are very important for the correct functioning of the bone, as they give the cells their needed blood supply and innervation.
