The theory of evolution can be proved by the comparison of DNA genetic sequences of organisms.
<u>Explanation:</u>
The evolution can be proved by following
- Homologous organs - they are organs that have similar basic structure but perform different functions. example: Human, Bird.
- Analogous organs-they are organs that perform same function but have different structure or basic design. example: Bird and insect.
- Fossils- the remains of dead animals and plants.
Dead organisms get decomposed by microbes, due to the absence of oxygen and moisture some body parts does not decompose.
The soft parts of body gets decomposed hard parts take time to decompose and get covered by sea, at these deep levels the decomposition stops and the hard parts remain preserved called fossils.
That is an ionic bond.
Ionic bonds are the type of bonds where there is transfer of an electron from one atom to another. The electron is removed from one atom and attached to another.
An example is salt, which is composed of two elements namely sodium and chlorine. Sodium readily gives up one its electrons and chlorine readily accepts it. Before sodium loses the electron, it has a positive charge and after the electron is gone it becomes negatively charged.
Chlorine on the other hand is positively charged before accepting the electron but after it does so, it becomes negatively charged.
These opposite charges attract the two elements together to form a relatively strong ionic bond.
A good title would be "The Cell Membrane: _____" and then insert what type of cell it is in the blank.
Answer:
No
Explanation:
Only what state it is in, soild, liquid or gas. Particals never change duering this.
metabolism takes place in stages because large free energy changes cannot occur in living organisms.
The group of chemical processes that allow organisms to continue to live is known as metabolism. Which compounds an organism will find nutritive and which toxic depends on the metabolic system of that organism. Because they enable organisms to drive desired events that need energy and won't happen on their own by linking them to spontaneous reactions that release energy, enzymes are essential to metabolism.
An animal or plant that is so little that you must use a microscope to view it is considered to be an organism. Not every chemical that is naturally found in living things is safe. Any organic, living system that performs as a separate unit is considered an organism in biology. Cells make up every living thing.
