Answer: Pretty sure its B
Explanation: When lithospheric plates move apart, it is called a divergent boundary. Mid-Ocean Ridges are found at divergent boundaries.
The other options don't make any sense as the answer.
Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
Answer:
Nervous stimulus action for muscle contraction
Explanation:
Nerve stimulation is sent to the sarcolemma, which are motor nerves at the neuromuscular junction (junction between the terminal part of a motor axon with a motor plate), after which nerve endings implant in the sarcolemma and form plaque on the surface of muscle fibers, which in turn transmit stimulus to the musculature.
Then, an electrical current (from the stimuli) is generated, it propagates through the muscle cell membrane, reaches the cytoplasm and triggers the muscle contraction mechanism.
Except the c) sweat gland
Epiphyseal plate is the structure within a bone that contains cartilage
cells that divide and increase the size of the bone until adulthood.
The epiphyseal plate, also known as epiphysial plate,or physis, or growth plate, is a hyaline cartilage plate in the metaphysis at each end of a long bone or diaphysis. The plate is found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line<span>.</span>
