Answer:
is supported by the orderly reinnervation of the frog optic tectum by regenerating retinal ganglion cells
Explanation:
In vertebrates, the optic tectum represents the major part of the midbrain (mesencephalon), which is involved in the development of motor skills such as body movement, eye movement, vision, hearing, etc. In lower vertebrates such as, for example, frogs, the primary target of the optic nerve fibers (i.e., retinal ganglion cells) is the optic tectum, which is responsible for the visually guided behavior. Roger Sperry was a neurobiologist and pioneer brain researcher who won the Nobel Prize in Medicine for his investigations in neuroscience and experimental neurology. In 1940, R. Sperry made different experiments involving the visual system of frogs and he observed that when optic fibers are damaged they grow back to their original localization in the optic tectum in order to re-establish the original set of neural networks. From this observation, R. Sperry proposed his chemoaffinity hypothesis, which states that neurons have individual identification tags that specify synaptic networks.
2. Coastlines are continually eroded by what
process? sc.6.E.6.2
A longshore currents
B parallel shore currents
C shortshore currents
D perpendicular shore currents
???????????
Coastlines are continually eroded by longshore currents, which are currents that flow parallel to the shoreline. These currents can be caused by the wind and waves, and they can transport sediment (such as sand and gravel) along the coast. As the sediment is moved and deposited, it can cause the coastline to change shape and erode over time.
Answer:
Explanation:
Coastlines are continually eroded by longshore currents.
Longshore currents are ocean currents that flow parallel to the shoreline. They are created when waves approach the shore at an angle, and the water is deflected by the friction of the bottom and the shape of the coastline. The resulting current flows parallel to the shore, and can cause erosion of the coastline over time.
Parallel shore currents and shortshore currents are not correct terms. Perpendicular shore currents are not a natural phenomenon and do not occur in the real world.

what are herbivorous plants?
Answer:
What is herbivory?
Herbivory is the act of eating plants. Herbivory occurs above and below ground. Herbivores may eat any part of the plant above the soil including leaves, stems, flowers, fruit and any part of the plant below the soil including roots and tubers.
What are herbivores plants?
Plants that are parasites can still be considered herbivores. A parasite is an organism that lives on or in another organism and gets its nutrients from it. Parasitic plants get their nutrients from other plants, called host plants.

describe the climate in coastal area near a warm ocean current
Answer:
The climate in coastal areas near a warm ocean current has higher temperatures as its moving away from the equator. The warm ocean currents cold water sinks which then allows light warm water to flow to the opposite direction usually away from the equator.

The climate in coastal area near a warm current will warm and rainy. The coastal regions will be maintained in a moderate temperature by warm current
What is warm ocean current?
Warm currents are heat transferring wind flowing from ocean parallel to the tropical and sub-tropical regions. Warm ocean current results in summer rainfall in the surrounding areas.
North Atlantic drift and Canary currents are examples of warm ocean currents. They are responsible to bring a moderate temperature level in coastal areas.
Warm ocean currents may sometimes mix with cold currents creating foggy weather in the near areas. Thus cold and dry climate may result in that areas.
Therefore, in general, warm ocean currents make the surrounding coastal areas in a moderate temperature with summer rainfall.

9 ¿Cuál es la similitud entre una marea muerta y una marea de primavera?
Answer (in English):
Both Spring and Neap tides occur twice each month. Spring tides occur twice each lunar month all year not regarding what season it is. Neap tides, which also occur twice a month, occur when the sun and moon are at right angles of each other.
En Espanol:
Tanto las mareas vivas como las mareas muertas ocurren dos veces al mes. Las mareas de primavera ocurren dos veces cada mes lunar durante todo el año sin importar en qué estación se encuentre. Las mareas muertas, que también ocurren dos veces al mes, ocurren cuando el sol y la luna están en ángulos rectos entre sí.
What is the end result of mitosis?
A) one cell with two identical copies of DNA
B) two cells with different copies of DNA
C) one cell with two different copies of DNA
Answer:
A) one cell with two identical copies of DNA
Explanation:
The end result of mitosis is one cell with two identical copies of DNA.
Answer: A) one cell with two identical copies of DNA
Explanation: Mitosis is a process of cell division that occurs in somatic cells (non-reproductive cells). It involves a series of steps that result in the formation of two identical daughter cells.
During mitosis, the parent cell undergoes several stages: prophase, metaphase, anaphase, and telophase. In prophase, the DNA condenses into visible chromosomes, and the nuclear membrane begins to break down. In metaphase, the chromosomes align in the middle of the cell. In anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, in telophase, the nuclear membranes reform around each set of chromosomes, and the cell begins to divide.
At the end of mitosis, each daughter cell contains the same number and type of chromosomes as the parent cell. This means that each daughter cell has an identical copy of the parent cell's DNA. The division of the cytoplasm then occurs in a process called cytokinesis, resulting in two separate daughter cells.

Which substances are needed for cellular respiration?
Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration. (10 points)
Chemical reactions that simulate cellular respiration follow the Law of Conservation of Matter when they are balanced. Six carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms are the same number of atoms as the reactants. C₆H₁₂0₆+60₂ — 6C0₂+6H₂0 .
What is cellular respiration?Through the process of cellular respiration, organisms mix oxygen with food molecules, directing the chemical energy contained in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste. Foods are broken down by organisms that do not require oxygen in a process known as fermentation.
What are atoms?A chemical element is uniquely defined by its atoms, which are small units of a substance. An atom is made up of a core nucleus and one or more negatively charged electrons that orbit it. The positively charged, comparatively hefty protons and neutrons that make up the nucleus may be present. The fundamental building components of matter are atoms. Atoms make up anything that has mass and occupies space.

Explained the effects of the use of antibodies in the control of a disease
Answer:
An antibody, also known as an immunoglobulin, is a large Y-shaped protein produced by B- cells and used by the immune system to identify and neutralize foreign objects such as bacteria and viruses.
Each tip of the “Y” of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision.
Though the general structure of antibodies is very similar, a small region at the tip of the protein is extremely variable, allowing millions of antibodies with different antigen binding sites to exist. This region is known as the hypervariable region.
Five isotypes of antibodies are found in different locations and perform different specific functions.
The base of the Y plays a role in modulating immune cell activity. This region is called the Fc region, and phagocytes may bind to it to initiate phagocytosis.
Antibodies that bind to surface antigens on a bacterium attract the first component of the complement cascade with their Fc region and initiate activation of the classical complement system.
