Identify cell structures used for direct contact in animal cells

1 answer:

3 0

<span>The answer is synapse and dendrite

</span><span>A synapse is a structure that allows a neuron (which is one type of animal cells) to pass an electrical or chemical signal to another neuron. That second neuron will then target a certain cell, causing a stimulus in the cell. This permits a direct contact between the cells.
</span>
<span> Dendrites are extensions of a neuron that recieve the signal and propagate it to the rest of the neuron.</span>

Answer:

Activation energy.

Explanation:

Activation energy may be defined as the minimum amount of energy required for the conversion of the reactant to the product. The reaction must have least activation energy to convert the reactant into product.

The reactant must pass this activation energy to convert them into the product. Catalysts are used in the reaction to lowers this activation energy and increases the rate of the chemical energy. The activation energy acts as the thermodynamic barrier that hinders the conversion of substrate into product.

Thus, the correct answer is option (A).

What a Stem Cells?

Stem cells are the body's raw materials- cells from which all other cells with specialized functions are generated.

What are specialized cells?

Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle.

What are unspecialized cells?

An unspecialized cell that can give rise to one or more different types of specialized cells, such as blood cells and nerve cells.

Do you think stem cell research should be allowed?

By watching stem cells mature into cells in bones, heart muscle, nerves, and other organs and tissue, researchers and doctors may better understand how diseases and conditions develop.

<h2>The Protein Structure</h2>

Explanation:

Protein structure is the three dimensional game plan of particles in an amino corrosive chain atom.
Proteins are polymers explicitly polypeptides framed from groupings of amino acids, the monomers of the polymer.By show, a chain under 30 amino acids is regularly distinguished as a peptide, rather than of a protein.
All proteins have primary, auxiliary and tertiary structures yet quaternary structures possibly emerge when a protein is comprised of at least two polypeptide chains.
The collapsing of proteins is additionally determined and fortified by the arrangement of numerous bonds between various pieces of the chain.
Connective tissues for the most part have barely any cells and extensive extracellular filaments including collagen and elastin.
Collagen is the absolute most abundant protein in the creature body and establishes roughly 25–35% of the entire body content.
