Answer:
The dna of every eukaryotic cell is stored in one or morechromosomes located in the nucleus
Explanation:
The nueclear compartment has 46 chromosomes each consisting of a long DNA molecule combined with proteins called histones (chromatin). When certain sectors of DNA are translated to generate RNA, these molecules leave the nucleus to begin protein synthesis.
Answer:
It is a hypothesis that explains the origin of evolutionary reversions.
Explanation:
A phylogenetic tree may indicate that genes required for forming anatomical structures such as wings are not completely lost and they are activated many times during the evolution.
Answer:
<u>The process of photosynthesis occurs in the chloroplast</u>. Photosynthesis can be described as a process in which plants convert water and carbon dioxide into glucose and oxygen. Oxygen is the by-product of the reaction. The energy for this reaction is taken by the chloroplast by trapping light energy of the Sun.
The reaction for photosynthesis can be written as:
6CO2 + 6H2O → C6H12O6 + 6O2
<u>The process of cellular respiration takes place in the mitochondria.</u> Respiration can be described as a process in which glucose and oxygen get converted into carbon dioxide and water. Energy is released by this process which is used for many cellular activities. Hence, mitochondria is known as the powerhouse of a cell.
The reaction of cellular respiration can be summed up as:
C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
Both, these processes provide energy for the working of cells.
Answer:
If <u>bacterial plague</u> (a.k.a. dental plague) accumulates around the teeth over a period of time, periodontal disease may result.
