The reptile is evolving over millions of years.
Answer:
This will reduce the average temperature of the planet and lessen the catastrophic effects of climate change.
Explanation:
Renewable resources do not emit greenhouse gases making them the cleanest, the most sustainable solution to prevent environmental degradation. If humans slowly transition to an energy system that is based on renewable technology, this will have a very positive economic consequences as well for economist foresee an increase in well-being and in employment and less cost while allowing development today without risking the future generations.
Answer:
A) the concentration of calcium ions in the sarcoplasm of a resting muscle
Explanation:
Sarcoplasmic reticulum is a system of the membranous sac that is present around each myofibril and is filled with calcium ions. When muscles are in the resting stage, calcium ions are stored in the sarcoplasmic reticulum.
As the muscle action potential triggers change in voltage-gated calcium ion channels of the sarcoplasmic reticulum, the channels are opened to release the calcium ions in the sarcoplasm. Increased calcium ion levels in sarcoplasm make the muscle fibers to contract.
Removal of acetylcholine from the synaptic cleft ends the production of muscle action potential and calcium ions are moved back from the sarcoplasmic reticulum.
Hence, lower levels of calcium ions are maintained in sarcoplasm when the muscles are in the resting stage.
The law of segregation is the Mendel’s laws or principles
explain that traits are passed from parents to offspring individually instead
of as pairs, groups or sets. So the correct option is option “C” as far as the
given question is concerned. This is a law or principle which states that
during the formation of gametes, two copies of each heredity factors separate
out so that the new offspring can get one factor of both the parents. This law
was the first law in this direction.
