Sleep is important for the body because it gives your body time to regain energy. People who sleep more tend to also have a better memory. Without sleep, both your body and mind become weaker and it becomes difficult to do everyday tasks.
All of those words are a form of pollution except for recycle. The differences are that they are different forms of pollution and they cause the ozone layer to weaken in addition they are causing global warming
Answer:
C. Bone fusion
B. Skull sutures
Explanation:
When lacking information about the age of a specimen, you can apply different techniques using the skeleton to find out the approximate age of the individual.
Usually, teeth are useful in determining the age of the specimens. But in some species, age determination through these structures is not easy. It requires laboratory elements and a high degree of precision.
Another way to determine the age of an individual is by analyzing the fusion degree of different bones.
Let us think about the skull of an animal or a person. It is composed of many bones that fit all together in a perfect way. Each bone is closely related to the adjacent ones and is usually involved in the same functions -feeding, breathing, hearing, among others-. The limits between these bones are the <u>suture lines</u>.
In the early post-natal stages, these bones are free. They fit all together, but they are not fused. But with time, they begin a fusion process that completes in adulthood. This fusion process occurs in the sutures.
As a general pattern, groups of bones with the same function get fused at the same time. Each group develops and fuses in a particular chronological sequence and is related to the adaptation to the environment and the biological habits.
The degree of fusion of the suture is a reliable indicator to differentiate age stages.
Answer:
B. sarcoplasmic reticulum ; sarcoplasm
Explanation:
A neural signal is the electrical trigger for calcium release from sarcoplasmic reticulum into the sarcoplasm. Electrical signals, called action potentials, travel along the neuron's axon connecting to individual muscle fibers at a neuromuscular junction. Neuron action potentials cause the release of neurotransmitters from the synaptic terminal into the synaptic cleft, where they can diffuse across the synaptic cleft and bind to a receptor molecule on the motor end plate.
