Answer:
Glucose
Explanation:
Because of the following factors, glucose serves as the brain's primary energy source. Glucose may be easily catabolized to provide energy to the brain since it cannot tolerate interruptions in energy flow. Since the brain cannot store calories, a quick supply of chemicals that can provide energy is essential for the brain's smooth operation. In this situation, blood can easily transfer glucose. Although fatty acids provide a source of energy for the rest of the body, they are unable to cross the blood-brain barrier because they are bound to blood albumin in blood plasma. These justifications explain why glucose serves as the brain's main source of energy. Ketone bodies could be the secondary source.

What is Genetic material?Genetic material may be defined as any substance found in the cells of plants, animals, microbial or other origins that hold genetic information and that departs it from one generation to the next.
In 1944, Avery and others concluded that the transforming material was pure DNA, not protein or RNA.
These investigators found that DNA extracted from a virulent strain of the bacterium Pneumococcus genetically transformed an avirulent strain of the organism into a virulent form.

What is a neuron?
Neurons are nerve cells that transmit nerve impulses.
These cells are formed in general by a cellular body, dendrites, and an axon.
The cellular body is called somaDendrites are cytoplasmic extensions that receive stimuli from other cells, The axon is a long formation capable of conducting electrochemical signals.There is a directly proportional relationship between the axon diameter and the conduction velocity. Mielinized fibers are thick and their conduction velocities are very fast.
The conduction velocity increases substantially in myelinated fibers because of the high concentrations of sodium channels in the Ranvier nodes, which are not myelinated areas and the diameter of the axon becomes thinner.
Every neuron forms connections with other neurons known as synapsis. As it happens in every synapsis between neurons when a presynaptic neuron sends information, a neurotransmitter is released.
Neurotrasmitters are chemical substances that travel through the synaptic cleft to the junctional area of the other neuron and bind to its receptors in the postsynaptic membrane.
The binding neurotransmitter-receptor produces a depolarization of the cell called an excitatory postsynaptic potential.
An action potential is initiated and spreads to the rest of the membrane depolarizing it.
B. Dendrites ⇒ 1) Receives information from another neuron's axon terminal through the Synapse. Sends messages to the soma.
C. Myelin Sheath ⇒ 3) Insulating substance that protects the axon and speeds up the transmission of the messages.
D. Nodes of Ranvier ⇒ 4) Gaps in the myelin sheath.

What occurs during a solar eclipse?
Earth is closest to the Sun.
There are small tides across Earth.
The moon’s shadow falls on Earth.
The moon is covered in Earth’s shadow.
Answer:
the Moon's shadow falls on Earth
Explanation:
The phenomenon in which the moon's shadow fall on earth or the earth casts its shadow on the moon is known as eclipse. During solar eclipse, moon's shadow falls on the earth. During lunar eclipse, earth's shadow falls on the moon.
٩ʕ◕౪◕ʔو
During a solar eclipse, the moon's shadow falls on Earth. Therefore, option (C) is correct.
When the Moon lines up between the Earth and the Sun, the Moon's shadow falls on the surface of the Earth. This is called a solar eclipse. This can only happen during a new moon, when the three stellar bodies are lined up in a straight line. During a cosmic event called an eclipse, the moon moves in relation to the Sun.
This causes the moon to block the Sun's light, which makes some parts of Earth temporarily darker or completely dark. Solar eclipses can be broken down into three different types: partial, annular, and total. These three types are determined by where the moon is in relation to the Sun and how big it seems to be. A solar eclipse takes place in the area where the moon's shade covers the sun. Therefore, option (C) is correct.

If you were given a cube of modeling clay, how would you shape it to have the greatest surface area-to- volume ratio?
To have the greatest surface area to volume ratio, it would be best to flatten the clay and create numerous projections.
The quantity of surface area per unit volume of an object or collection of objects is known as the surface-area-to-volume ratio (also known as the surface-to-volume ratio or abbreviated as SA:V). A cell's volume increases proportionately more than its surface area as its size decreases. As a result, the surface area to volume ratio is higher for smaller objects. For cells, a high surface area to volume ratio is crucial. There is more plasma membrane compared to the interior of the cell when surface area exceeds volume. This makes it feasible for materials to be moved into, out of, and around the cell as effectively as possible.The fact that a surface area must be sufficient to hold the volume helps to explain why most cells are tiny in size.

During germination, starch stored in the cotyledons is broken down .
describe how the breaking down of starch occurs.
Answer:
During germination, starch is degraded by the combined actions of several hydrolytic enzymes such as α-amylase, β-amylase, and α-glucosidase to provide energy for the embryo.
Enzymes hydrolyze starch into simpler sugars during germination, providing a source of energy for seedling growth.
Plant seeds convert their cotyledons' starch into sugars during germination. The seedling needs energy until it can photosynthesise and manufacture its own nutrition. Amylases digest starch. Amylases hydrolyze starch into glucose and maltose. Starch hydrolysis disrupts glycosidic connections between glucose molecules by adding water molecules.
The seedling can easily transfer and convert glucose and maltose into energy through cellular respiration. This energy powers metabolic processes and development when the seedling emerges from the seed coat and grows roots and branches. The plant converts stored starch into sugars to give energy during early development before photosynthesis takes over.
