Yes sort of organisms millions of years ago break down into oil which could be small organisms
Answer:
a and b
Explanation:
The growth of adipose tissue in newborns is directly linked to the fact that they do not have proper body temperature control, so fat acts as a thermal insulator in order to maintain a constant temperature, also, breast milk density can also influence baby fat gain.
For the first six months the baby still has a lot of fluid retention and so it may give the impression that he is getting fatter, but after the first six months until the end of the first year, the baby tends to lose this fluid, decreasing on average 10% of body weight.
<u>Girls</u> in adolescence and pre-adolescence have a tendency to gain weight due to the enormous hormonal load they receive at puberty, as well as other factors such as poor diet.
The same does not happen as often in <u>boys</u> because a good part tends to have a "leap" growth in puberty, favoring weight loss. The process of fattening in teenage boys is more associated with sedentary practices and consumption of junk food.
Answer:
The correct answers are: Synaptic Active Zones, Exocytosis.
Explanation:
- An impulse after travelling along the dendrites, cell body and axon of a neuron reaches the axon endings in the form of an action potential (signal transmitted by the activation of voltage gated sodium and potassium channels present on the plasma membrane of the neurons).
- At the axon ending or the pre-synaptic region, the action potential triggers the opening of the voltage dependent calcium channels, that promotes the influx of calcium ions into the pre-synaptic region of the neuron.
- This process triggers the fusion of the neuro-transmitter carrying vesicles with the plasma membrane in the pre-synaptic region of the neuron.
- As a result of fusion the neurotransmitter is released into the synaptic cleft.
- At the pre-synaptic region of the neuron, there is a huge concentration of neuro-transmitter carrying vesicles which remain adhered to proteins called CAZ (cytomatrix at the active zone) proteins. These proteins help the neurotransmitter carrying vesicles to remain tethered or docked to the pre-synaptic membrane in the axon terminal of the neuron. They together form the Synaptic Active Zone.
- In response to calcium ion influx these proteins help the neurotransmitter carrying vesicles to fuse with the plasma membrane in the pre-synaptic region of the neural axon and release the neurotransmitter into the synaptic cleft.
- The process of fusion of the neurotransmitter carrying vesicles with the plasma membrane in the pre-synaptic region of the neural axon followed by the release of the neurotransmitter into the synaptic cleft is known as Exocytosis.
This kind of evolution where both species are evolving in response to one another is called coevolution.
