New, inheritable characteristics can result from the recombination of genes during meiosis and <span>mutations in the genes found in sex cells. The correct option among all the options that are given in the question is the first option. I hope that this is the answer that has actually come to your desired help.</span>
Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.
Circle should be on number 13 because three chromosomes means that there’s a disability or abnormality.

Some of the key terms in community ecology are Intraspecific Interaction, interspecific interaction, competitive exclusion, mutualism.
<h3>
What is community ecology?</h3>
- Community ecology aims to provide solutions to these and other community-related concerns.
- An ecological community is a collection of organisms that coexist or may coexist in a given area. Communities are connected by a shared environment and a web of relationships between the many species.
- An ever-expanding and comprehensive area of ecology is community ecology. Ecologists look at the variables that affect species distribution, community structure, and biodiversity. Interactions with the abiotic environment and the wide variety of interactions that take place between species are two examples of these elements.
- The foundation of the majority of community ecology study is species interactions, such as competition, predation, herbivory, parasitism, and mutualism.
