Many autotrophs make food through the
process of photosynthesis, in which light energy from the sun is changed
to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
Answer: A) Two atoms share electrons so they can fill their outer shells
Explanation: A covalent bond is a type of bond formed by sharing equal number of electrons between two non-metal atoms so that both of them can attain a stable octet or duplet structure of noble gases.
In covalent bonding, there is no loss or gain of electrons between atoms. For example, the formation of chlorine molecule, chlorine atom has seven electrons in its outermost shell, remaining one electron to attain an octet structure of noble gases. Two chlorine atoms share one pair of electron, each chlorine atom donating one electron to form a pair so that each atom in the chlorine molecule attains an octet structure..
Answer:
Mitosis is the process of cell division to make more cells, meiosis is the process of sperm and egg cells dividing to make a baby.
Explanation:
Answer:
Gap junctions.
Explanation:
Gap junctions may be defined as the intercellular connection present between the cells of the animals. They are made of the connexons and present in all cells of the body except skeletal muscles.
The small molecules and ions can easily pass through the gap junctions. The neighbouring cells can pass the molecules and communicates with each other through the gap junctions. They are known as macula communicans. Invertebrates have the gap junction made of innexin.
Thus, the answer is gap junctions.
