The virus needs to speak the molecular language of cells. This is how he manages to dominate and enslave them so that they become factories for new viruses, producing the proteins that the infectious agent requires to assemble its descendants. If this conversation is not fine-tuned, even if the virus has the key and enters, it is doomed to failure.
Why does a virus lethal to us not infect animals?For a virus to be able to enter a cell, it must have the right key. And this key, which are the proteins on the surface of viruses, has to enter the correct lock, the receptors that are on the cell membrane. Cells are actually houses with many different doors and locks. Some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.
With this information, we can conclude that some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

b-1), c-3), d-4), e-2), f-5),
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.

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.

What muscular tubes, not supported by cartilage, help regulate airflow into and out of the lungs?
A. trachea
B. diaphragm
C. alevoli
D. bronchioles
Bronchioles are small, muscular tubes in the respiratory system that help regulate airflow. The correct option is B.
Bronchioles help regulate the airflow by contracting and relaxing their smooth muscles, allowing for adjustments in the amount of air entering and exiting the lungs
Their muscular walls can constrict or dilate, allowing the body to adjust the volume of air reaching different parts of the lungs based on factors like physical activity or oxygen demands. This regulation ensures efficient gas exchange and helps maintain optimal respiratory function.
Unlike the trachea and larger airways, bronchioles lack cartilage support, which gives them the flexibility to respond to the body's respiratory needs.
