Answer:</h2>
Removal of the tarnish from the silver is a <u>physical change</u>.
<h2>
Explanation:</h2>
The type of change which doesn't produce any new substance is called as physical change. Tarnish refers to the thin black layer that is formed on the silver. Formation of tarnish is chemical change as due to oxidation a black color layer is formed.
On the other hand, removal of tarnish from silver is considered as physical change as no new product is formed and only we are obtaining the silver in its pure form.
Answer:
The correct answer would be mitosis or M phase.
Mitosis or M phase is the phase of the cell cycle during which the actual division of the cell takes place that is, the division of nuclear content. It is also termed as karyokinesis.
It is primarily divided into four stages:
- Prophase
- Metaphase
- Anaphase
- Telophase.
It results in the equal distribution of chromosomes into two daughter cells.
It is followed by cytokinesis by which cytoplasmic content is equally divided into the two daughter cells.
The bands of circular muscle structures that are located at the cuttlefish skin are most likely responsible for the changes of its outer covering. In addition, the colour cells that are present on the cuttlefish skin were estimated to be about 10 million which is why it was coined "the chameleons of the sea."
Answer;
A. leaf to mouse
Explanation;
-Considering the fact that the amount of energy at each trophic level reduces as it moves through an ecosystem from the lowest trophic level which happens to be producers (plants). And about 10 percent of this energy at any trophic level is transferred to the next level since the rest is lost largely through metabolic processes as heat.
-It means that the lower the trophic level the higher the energy obtained, for instance from producers to primary consumers, more energy is passed since it is the first passage of energy.
Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.
