Answer:
can lead to natural selection
Explanation:
<h2>
</h2><h2>
Unequal reproductive success<em> _can lead to natural selection_____.</em></h2>
This is because if there is unequal reproductive success then one of the organisms is <em>better suited for reproducing, surviving, and passing down their genes to their offspring</em> rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where <em>i</em><u><em>ndividuals better suited for their environment produce more and have better survivality. </em></u>
So overtime, the organism which is weaker (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in a way "<u>Nature selected"</u><u> </u>the better fit organism.
Answer:
Family is the answer
Explanation:
Mature woman have a lot of responsibilities on there shoulder, th house, the kids, the budget planning, job work etc. They just can't have a single minute to waste upon, they have to handle so many things, and they do that all with single hand. They make things perfect and that takes a lot of their time, after doing this all daily chores even Jesus wouldn't have energy to do anything, so how do you expect any human. Woman plays a very responsible role from beginning of the day to night.
Myofibrils are the building blocks or contractile unit of each muscle fiber. The tiniest functional unit of skeletal muscle, the sarcomere, is found in the myofibrils and is made up of protein filaments: actin (thin) and myosin (thick).
Answer:
Neurons are in charge of receiving stimuli from the environment, transforming them into nervous excitations and transmitting them to the nerve centers, where they organize themselves to give a response.The cycle of depolarization and hyperpolarization of the membrane and return to the resting membrane potential is called the action potential, an all-or-nothing reaction that can occur at rates of up to 1,000 pulses / second. Membrane depolarization that occurs as voltage gate Na + channels open at one point on an axon passively spreads a short distance and triggers the opening of adjacent channels, resulting in the generation of another action potential. In this way the depolarization wave, or nerve impulse, is conducted along the axon.
Explanation:
Neurons are highly specialized cells whose central function consists in the generation and transmission of signals, in order to communicate with the other neurons of the nervous system and with the outside of the organism. They are made up of three parts: the cell body, the dendrites, and the axon. Dendrites are extensions of the cell body with short, tubular branches, through which each neuron receives signals from other neurons. These signals are added or averaged, and in the event that the total intensity of the received stimulus is greater than a certain threshold, the neuron will generate and emit an electrical response signal. This signal will be sent through the axon, which will transmit the information to other neurons through chemical exchange. The axon divides near the end into thin branches that contact other neurons. The point of contact is called the synapse. At the synapse, there is a gap between the two cells called the synaptic cleft. The synapse is produced by the release of chemicals from the presynaptic neuron that excites the postsynaptic, transmitting the informational code. The arrival of an impulse at the end of a nerve fiber causes a chemical compound, a transmitter substance, to be released, which excites the neighboring neuron. The same neuron may have inhibitory and excitatory connections with different neurons, for which it will need to produce different chemicals that act as transmitters. A neuron receives and integrates multiple stimulations through the synapses, those received by the dendrites are added to those received in the soma so that the electrical potential of the cell membrane ends up exceeding the threshold and originates a nerve impulse in the area of the axonal cone. Nerve impulses are electrical signals generated by the spike trigger sites (axon cones) of a neuron as a result of membrane depolarization, which are conducted along the axon to its termination. The transmission of impulses from the endings of a neuron to another neuron, a muscle cell or a gland occurs at the level of the synapses.
