C) Sprout every year, year after year
Explanation:
A perennial plant or simply perennial is a plant that lives more than two years. Some sources cite perennial plants being plants that live more than three years. The term is often used to differentiate a plant from shorter-lived annuals and biennials.
Answer:
A. Calcium would be transported to the sarcoplasmic reticulum therefore contractions would cease.
Explanation:
A muscle fibre will stop contraction immediately ATP is used up. Also, muscle contraction will end as soon as the information from the motor neuron stops. This repolarizes the sarcolemma and T-tubules, thereby closing the voltage-gated calcium channels in the sarcoplasmic reticulum. Calcium ions are then pumped back into the sarcoplasmic reticulum, in order for tropomyosin to cover the binding sites on the actin strands again.

animals that Haeckel recognized but microscopic organisms such as Bacteria, Archaea and protozoa, as well.</span>
<span>vacuoles are those cell which help in storage of water and minerals.
plant have one vacuoles in plant cell but animal have abundant of small vacuoles cell. If there are no vacuoles there would be no reserves of food minerals, water, minerals etc in cells.</span>
The answer is; Jane would be right.
The atom was discovered be more of empty space. The mass of an atom is mainly attributed to the mass of the nucleus which occupies a very small fraction of the size of the atom. The nucleus is Located in the center surrounded by orbiting electrons.
The Geiger–Marsden experiment, where alpha particles are accelerated onto a thin aluminum foil proved this theory by Ernest Rutherford. Some of the particles were deflected by the foil and this was attributed to the dense nucleus of the aluminum atoms in the foil. The other particles passed through because most of the atoms are made of empty space.
