Differences Between Pteridophytes and Seed Plants

Pteridophytes don't produce cones, flowers, or fruit, unlike these seed plants. Instead, Pteridophytes produce spores. Spores are living, single-celled structures that are essential to the life cycle of many plants.

Biological classification is important because it allows scientists to study organisms in a ___ way​
puteri [66]

Answer:

Systematic.

Explanation:

Biological classification is important because it allows scientists to study organisms in a systematic way​.

In Science, this biological classification of living organisms based on similarities or characteristics such as eyes, number of legs, etc., is generally referred to as taxonomy.

Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.

Hence, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.

Vlad1618 [11]

Answer:

C-An action potential reaches the presynaptic membrane.

E-Sodium channels on the motor end plate open.

A-Sodium enters the muscle fiber, creating an end-plate potential.

B-Neurotransmitter is released into the synaptic cleft.

D-Neurotransmitter binds to a receptor on the postsynaptic membrane.

Explanation:

In the neuromuscular junction, there is a presynaptic membrane, a postsynaptic membrane, and between these two, there is a gap called the synaptic cleft.

First, an action potential reaches the presynaptic membrane, causing the opening of sodium channels and the entering of Sodium ions to the muscle fiber creating an endplate potential. As a consequence of this, the neurotransmitters contained in vesicles travel down up to the presynaptic membrane, where they release their content into the synaptic cleft. Then, the neurotransmitters bind to the receptors in the ion channels of the postsynaptic terminal. This causes the opening of the ion channels and a rush of ion Sodium to the inside of the postsynaptic membrane, creating an action potential that will travel from cell to cell.
